The embodiments described herein relate generally to the field of ophthalmic therapies and more particularly to the use of a microneedle for delivery and/or removal of a substance, such as a fluid therapeutic agent into and/or from ocular tissues for treatment of the eye.
Although needles have been used in transdermal and intraocular drug delivery, there remains a need for improved microneedle devices and methods, particularly for delivery of substances (e.g., drugs) into the targeted regions of the eye. Many inflammatory and proliferative diseases in the posterior region of the eye require long term pharmacological treatment. Examples of such diseases include macular degeneration, diabetic retinopathy, and uveitis. It is often difficult to deliver effective doses of a drug to the posterior region of the eye using conventional delivery methods such as topical application, which has poor efficacy, and systemic administration, which often causes significant side effects. For example, while eye drops are useful in treating conditions affecting the exterior surface of the eye or tissues at the front of the eye, the eye drops are not significantly carried to the back of the eye, as may be desired for the treatment of some of the retinal diseases listed above.
Although there have been advances in the past decade regarding the utilization of ocular injection and systemically delivered substances for the treatment of ocular disorders, obstacles still exist. For example, direct injection into the eye (e.g., into a portion of the sclera and/or the vitreous) using conventional 27 gauge or 30 gauge needles and syringes can be effective but often requires professional training and raises safety concerns. Moreover, the anatomy of the eye can make insertion of a conventional 27 gauge or 30 gauge needle into ocular tissue challenging. For example, the eye has a lower modulus of elasticity than skin, and thus will deform more readily in response to an applied force compared to deformation of the skin in response to the same applied force. Accordingly, conventional needles that are designed to pierce skin or other tissue may not be suitable for piercing ocular tissue.
In addition, many known methods of direct injection of a drug into the eye include inserting a needle or a cannula at an acute angle relative to a surface of the eye, which can make controlling the depth of insertion challenging. For example, some such methods include controlling the angular orientation of the needle such that the injected substance exits the needle at a particular locations. Moreover, some known methods of injecting substances into ocular tissue include using complicated visualization system or sensors to control the placement of the needle or cannula.
Moreover, in some instances, such as when treating intraocular tumors, tumors seeds and/or precancerous tissue within the vitreous can be spread through the passageway defined by the insertion of the needle (i.e., a needle tract), which can increase the risk of complications from the tumor. Thus, known methods that result in multiple needle tracts, needle tracts having a large diameter and/or length can result in increased risk of complications.
In some instances, the relative size of the anatomy of the eye can present challenges to treatment of ocular disease. For example, in the treatment of retinoblastoma in pediatric cases, the target insertion site of a needle (e.g., the ciliary body) is significantly smaller than a corresponding target insertion site in an adult case. In such instances, the precise placement of the needle can present a challenge for physicians, resulting in an increased chance of tissue damage and an increase in cost of the procedure. In addition, the anatomy of the eye in pediatric cases can be such that a standard 27 gauge or 30 gauge needle is too large, making insertion to a desired depth into ocular tissue a challenge.
Thus, a need exists for improved methods and devices for delivering substances to ocular tissue.
Devices and methods described herein relate generally to intraocular treatment and more particularly to the use of microneedles for treatment of ocular tissue. In some embodiments, a microneedle has a proximal end portion and a distal end portion and defines a lumen. The proximal end portion is configured to be coupled to a cartridge to place the lumen in fluid communication with the cartridge. The proximal end portion includes a base surface that is configured to be placed in contact with a surface of a target tissue. The distal end portion of the microneedle includes a beveled surface. The beveled surface defines a first bevel angle and a second bevel angle different from the first bevel angle.
In some embodiments, a microneedle has a proximal end portion and a distal end portion and defines a lumen. The proximal end portion is configured to be coupled to a cartridge to place the lumen in fluid communication with the cartridge. The proximal end portion includes a base surface configured to contact a surface of a target tissue. The distal end portion includes a beveled surface defining a tip angle of less than about 20 degrees and a ratio of a bevel height to a bevel width of less than about 2.5.
In some embodiments, a method for delivering a substance to a target tissue of an eye includes inserting a microneedle into an eye such that a distal edge defined by a beveled surface of the microneedle does not extend through the choroid of the eye. The beveled surface of the microneedle defines a tip angle of less than about 20 degrees. The beveled surface has a height such that an opening defined by the beveled surface is within at least one of a suprachoroidal space or a lower portion of the sclera. A substance is conveyed from a cartridge coupled to a proximal end portion of the microneedle into the suprachoroidal space via the opening defined by the beveled surface
In some embodiments, a microneedle for ocular drug delivery and/or ocular tumor removal includes a beveled surface. The beveled surface of the microneedle defines a tip angle of less than about 20 degrees and a ratio of a bevel height to a bevel width of less than about 2.5. The beveled microneedle, in one embodiment, allows for accurate and reproducible drug delivery to the suprachoroidal space (SCS) of the eye. In other embodiments, the beveled microneedle is used in a pediatric ocular drug delivery methods to deliver one or more drugs to the vitreous of a pediatric eye. Advantageously, the beveled microneedle, when used in the pediatric eye, minimizes the length of the needle tract, thereby minimizing the opportunity for a tumor cell(s) to re-seed in the needle tract.
In some embodiments, a microneedle has a proximal end portion and a distal end portion and defines a lumen. The proximal end portion is configured to be coupled to a cartridge to place the lumen in fluid communication with the cartridge. The proximal end portion includes a base surface that is configured to be placed in contact with a surface of a target tissue. The distal end portion of the microneedle includes a beveled surface. The beveled surface defines a first bevel angle and a second bevel angle different from the first bevel angle. In some embodiments, the first bevel angle is less than the second bevel angle. In some embodiments, the first bevel angle is less than about 20 degrees and the second bevel angle is less than about 30 degrees.
In some embodiments, a microneedle has a proximal end portion and a distal end portion and defines a lumen. The proximal end portion is configured to be coupled to a cartridge to place the lumen in fluid communication with the cartridge. The proximal end portion includes a base surface that is configured to be placed in contact with a surface of a target tissue. The distal end portion of the microneedle includes a beveled surface. The beveled surface defines a tip angle of less than about 20 degrees and a ratio of a bevel height to a bevel width of less than about 2.5.
In some embodiments, a hollow microneedle and/or microneedle assembly for delivery of a drug to an eye is provided. In some embodiments, the hollow microneedle includes a distal end portion and a shaft extending from a cartridge housing. The needle can be disposed within a needle cap prior to use. A distal end of the microneedle includes a bevel that corresponds, at least partially, to a target location within the eye. The cartridge housing can receive a cartridge containing a therapeutic agent. In some embodiments, the microneedle is configured to allow the entire shaft or substantially the entire shaft of the microneedle to be inserted into the eye such that the distal end portion of the microneedle is disposed within the target location (e.g., the suprachoroidal space) of the eye.
In some embodiments, a microneedle for delivery of a drug to a pediatric eye is provided. The microneedle may be a hollow microneedle, or a solid microneedle. In some embodiments, the microneedle includes a bevel and a shaft extending from a base, and defines a lumen. The microneedle is configured to facilitate the insertion of the entire shaft or substantially the entire shaft of the microneedle into the pediatric eye such that a drug formulation can be deposited, injected and/or infused in the vitreous of the pediatric eye without damaging the lens or retina.
In some embodiments, a method for delivering a substance to a target tissue of an eye includes inserting a microneedle into an eye such that a distal edge defined by a beveled surface of the microneedle does not extend through the choroid of the eye. The beveled surface of the microneedle defines a tip angle of less than about 20 degrees. The beveled surface has a height such that an opening defined by the beveled surface is within at least one of a suprachoroidal space or a lower portion of the sclera. A substance is conveyed from a cartridge coupled to a proximal end portion of the microneedle into the suprachoroidal space via the opening defined by the beveled surface.
In some embodiments, a method for delivering a drug to the suprachoroidal space of an eye includes inserting a distal end of a hollow microneedle into the sclera, wherein the entire shaft or substantially the entire shaft of the microneedle is inserted into the eye at an angle of approximately 90 degrees. Upon insertion, a drug is conveyed, injected and/or infused through the microneedle, through the sclera, and into the suprachoroidal space without damaging the lens, retina, or other ocular tissue.
In some embodiments, a method for delivering a drug to the suprachoroidal space of an eye includes inserting a distal end of a hollow microneedle into the sclera, wherein the entire shaft or substantially the entire shaft of the microneedle is inserted into the eye at an angle of approximately 90 degrees. Upon insertion, a drug is infused through the microneedle, through the sclera, and into the suprachoroidal space without damaging the lens, retina, or other ocular tissue. In a further embodiment, the microneedle, when inserted into the eye for suprachoroidal drug delivery, does not puncture the choroid.
In some embodiments, a method for delivering a drug to the vitreous of a pediatric eye includes inserting the distal end of any of the microneedles described herein through the ciliary body of the pediatric eye, wherein the entire shaft or substantially the entire shaft of the microneedle is inserted into the eye at an angle of approximately 90 degrees. A drug is then injected and/or infused through the lumen of the microneedle into the vitreous.
In some embodiments, a method for delivering a drug to the suprachoroidal space of an eye is provided. In some embodiments, the method comprises inserting a distal end of a hollow microneedle into the sclera or suprachoroidal space, wherein the entire shaft or substantially the entire shaft of the microneedle is inserted into the eye at an angle of approximately 90 degrees. Upon insertion, a drug is injected and/or infused through the microneedle into the suprachoroidal space without damaging the lens, retina, and/or other ocular tissue.
In some embodiments, a method for treating retinoblastoma includes inserting a distal end of a microneedle defining a lumen through the ciliary body of the human eye, wherein the entire shaft or substantially the entire shaft of the microneedle is inserted into the eye, and infusing a topotecan formulation through the microneedle and into the vitreous of the eye.
In some embodiments, the methods provided herein are used to deliver a growth factor to the vitreous of the eye, for example, a pediatric eye. In some embodiments, the growth factor is vascular endothelial growth factor (VEGF). In other embodiments, the drug delivered with the methods provided herein is a VEGF inhibitor. In some embodiments, the VEGF inhibitor is an antibody, e.g., bevacizumab. In still other embodiments, both VEGF and a VEGF inhibitor are delivered to the vitreous of a pediatric eye via any of the methods and microneedles described herein. In a further embodiment, the length of the microneedle is such that the entire shaft or substantially the entire shaft of the microneedle is inserted into the eye without damaging the lens or retina, or other ocular substructures.
In some embodiments, a method for decreasing the tumor size of an intraocular tumor in a patient includes infusing a topotecan formulation into an eye having one or more intraocular tumors, such as, for example, a retinoblastoma tumor. The topotecan formulation is infused using at least one microneedle provided herein. In some instances, the patient in need thereof is a pediatric patient. In one embodiment, the drug (e.g., a chemotherapeutic agent such as topotecan) is infused into the eye in an hourly, daily, or weekly dosing regimen. In one embodiment, the drug is infused into the eye once weekly. In a further embodiment, the drug is infused into the eye once weekly for two, three, four, five, or six weeks. In another embodiment, the drug is infused into the eye once weekly for three weeks. In another embodiment, the drug is infused into the eye at a dosage of about 10 μg, e.g., in a 50 μL, volume. In one embodiment, the tumor area is reduced to a greater extent in comparison to the reduction in tumor area that occurs when topotecan is infused using a 30 gauge needle.
In another aspect, a method for extraction of a biological tissue, fluid, or molecular sample from the vitreous, sclera or corneal stroma of a patient's eye (e.g., a pediatric eye) using any of the microneedles described herein is provided. In a further embodiment, the biological sample is a cancer cell or cells, for example, a retinoblastoma cell or cells. In a further embodiment, the extraction of the biological sample does not result in the accumulation of the biological tissue, fluid, or molecule in the needle tract. In another embodiment, the extraction of the biological sample results in less accumulation of the biological tissue, fluid, or molecule in comparison to the accumulation of the biological tissue, fluid, or molecule in the needle tract that occurs when the biological sample is extracted using a 27 gauge or 30 gauge needle.
In another embodiment, provided herein are methods for decreasing the number of vitreous seeds of an intraocular tumor in a patient, e.g., a retinoblastoma tumor. In a further embodiment, the number of vitreous tumor seeds in the patient is reduced to a greater extent compared to the reduction in the number of vitreous tumor seeds that are present after infusion of topotecan using a 30 gauge needle. In even a further embodiment, the patient is a pediatric patient.
In some embodiments, a microneedle, such as those described herein, is configured to be at least partially inserted into the sclera to deliver a therapeutic agent to a target region of the eye (e.g., the suprachoroidal space). The microneedles described herein include a bevel, which in comparison with bevels of standard needles, allows for ease of penetration into the sclera and/or suprachoroidal space with minimal collateral damage. The microneedles define a narrow lumen (e.g., greater than or equal to 30 gauge, 32 gauge, 34 gauge, 36 gauge, etc.) that can allow for suprachoroidal drug delivery while minimizing the diameter of the needle tract caused by the insertion of the microneedle. The lumen, the configuration of multiple bevel angles and the bevel aspect ratio of the microneedles described herein are distinct from the bevel included in standard 27 gauge and 30 gauge needles. Moreover, the entire shaft (or substantially the entire shaft) of the microneedle can be inserted into the eye using the methods provided herein, allowing for less uncertainty and less variability in drug delivery. In one embodiment, the microneedle has a length of about 4 mm compared to, for example, a length of about 10 mm for a 27 gauge and/or 30 gauge needle. In such embodiments, the size of the microneedle can be more appropriate for insertion into the pediatric eye than the size of a 27 gauge and/or 30 gauge needle.
In some embodiments, a microneedle defines a lumen and includes a distal end portion and a shaft extending from a cartridge housing. The microneedle can be disposed within a needle cap prior to use. The cartridge housing can receive a cartridge containing a therapeutic agent. The arrangement of the cartridge housing and the microneedle can allow the entire shaft or substantially the entire shaft of the microneedle to be inserted into the eye. In some embodiments, the arrangement of the distal end portion of the microneedle can correspond to a target tissue of the eye. For example, in some instances, the entire shaft or substantially the entire shaft can be inserted into the eye such that the distal end portion of the microneedle is disposed within the sclera or suprachoroidal space of the eye without damaging other ocular tissues. In some instances, the lumen of the microneedle defines a flow path through which a drug formulation is conveyed and/or infused when the microneedle is disposed within the sclera or the suprachoroidal space. For example, in some instances, the distal end portion of the microneedle can be inserted into a target region in or near the sclera. The relatively expandable suprachoroidal space can have a smaller resistance to flow than the relatively incompressible surrounding tissue. Thus, as a drug formulation is conveyed and/or infused into the target region, the drug formulation can naturally flow into and expand the suprachoroidal space. As a result, the drug formulation can be conveyed to an anterior region of the eye (e.g., the choroid, retina, etc.) without surgically accessing (e.g., cutting) the target region.
In some embodiments, the microneedle is hollow and defines a narrow lumen. The narrow lumen (e.g., greater than or equal to 32 gauge) of the microneedle can allow for drug delivery to the posterior segment of the eye, for example, to the vitreous, as well as aspiration of cellular material from the eye. The microneedle is much smaller than standard 27 gauge and 30 gauge needles which are now commonly used for intraocular injection. Moreover, the entire shaft (or substantially the entire shaft) of the microneedle is inserted into the eye in the methods provided herein, allowing for less uncertainty and less variability in drug delivery. Such embodiments can be particularly useful in pediatric patients, as the eyes have a very short ciliary body (e.g., as described herein with reference to Table 1 below). The embodiments described herein can achieve greater reproducibility in drug delivery and reduce the risk of damage to the lens and/or retina when compared to conventional needles.
In some embodiments, a method includes inserting a hollow microneedle into an eye of a patient at an insertion site; the microneedle has a tip end that defines an opening. Upon insertion, a triamcinolone composition (e.g., triamcinolone particles) is delivered over a period of time through the inserted microneedle and into the suprachoroidal space of the eye. During the time period the delivered drug formulation flows within the suprachoroidal space away from the insertion site. In some embodiments, the composition comprises triamcinolone or triamcinolone acetonide nanoparticles or microparticles. In some embodiments, the microparticles in the composition have a D50 of 2 μm or less and/or a D90 of less than 10 μm.
In yet another aspect, a method for delivering a drug into the vitreous of an eye is provided. In some embodiments, the method includes inserting a distal end of a microneedle into a vitreous of a human eye, e.g., a pediatric eye, wherein the entire shaft, or substantially the entire shaft of the microneedle is inserted into the eye. The distal end of the microneedle includes a bevel that corresponds, at least partially, to a target location within the eye. The microneedle defines a lumen configured to provide a flow path for a drug when the microneedle is disposed within the vitreous. The method further includes removing the microneedle after a desired amount of drug is delivered.
In some embodiments, a method for drug delivery to the pediatric eye is provided. The method includes inserting a microneedle into the pediatric eye, so that the entire shaft or substantially the entire shaft of the microneedle is inserted into the pediatric eye during drug delivery. In this regard, the user (e.g., a doctor, nurse, etc.) of the device is not required to determine the depth of insertion of the device, which allows for greater reproducibility in drug delivery methods and/or cellular aspiration methods. Moreover, the bevel structure (e.g., bevel length and bevel angle) of the devices presented herein eliminate or substantially reduce damage to the lens and retina when inserting the device through the ciliary body and into the vitreous of the eye.
As used in this specification, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, the term “a member” is intended to mean a single member or a combination of members, “a material” is intended to mean one or more materials, or a combination thereof.
As used herein, the words “proximal” and “distal” refer to the direction closer to and away from, respectively, an operator (e.g., surgeon, physician, nurse, technician, etc.) who would insert the medical device into the patient, with the tip-end (i.e., distal end) of the device inserted inside a patient's body first. Thus, for example, the end of a microneedle described herein first inserted inside the patient's body would be the distal end, while the opposite end of the microneedle (e.g., the end of the medical device being manipulated by the operator) would be the proximal end of the microneedle.
As used herein, a “set” can refer to multiple features or a singular feature with multiple parts. For example, when referring to set of walls, the set of walls can be considered as one wall with distinct portions, or the set of walls can be considered as multiple walls.
As used herein, the terms “about” and “approximately” generally mean plus or minus 10% of the value stated. For example, about 0.5 would include 0.45 and 0.55, about 10 would include 9 to 11, about 1000 would include 900 to 1100.
The embodiments and methods described herein can be used to treat, deliver substances to and/or aspirate substances from, various target tissues in the eye. For reference,
As used herein, the term “suprachoroidal space,” which is synonymous with suprachoroid, or suprachoroidia, describes the space (or volume) and/or potential space (or potential volume) in the region of the eye 10 disposed between the sclera 20 and choroid 28. This region primarily is composed of closely packed layers of long pigmented processes derived from each of the two adjacent tissues; however, a space can develop in this region as a result of fluid or other material buildup in the suprachoroidal space and the adjacent tissues. The suprachoroidal space can be expanded by fluid buildup because of some disease state in the eye or as a result of some trauma or surgical intervention. In some embodiments, the fluid buildup is intentionally created by the delivery, injection and/or infusion of a drug formulation into the suprachoroid to create and/or expand further the suprachoroidal space 36 (i.e., by disposing a drug formulation therein). This volume may serve as a pathway for uveoscleral outflow (i.e., a natural process of the eye moving fluid from one region of the eye to the other through) and may become a space in instances of choroidal detachment from the sclera.
The dashed line in
The cartridge housing 130 can be coupled to and/or receive the cartridge 140 such that at least a portion of the cartridge 140 is disposed within the cartridge housing 130. The cartridge 140 can be any suitable device configured to house or contain a drug formulation (e.g., a prophylactic agent, a therapeutic agent, a diagnostic agent or any of the formulations described herein). More specifically, the cartridge 140 can include a set of walls that define an inner volume within which a drug formulation is disposed. The cartridge 140 can be moved between a first configuration and a second configuration to expel the drug formulation disposed within the inner volume. For example, in some embodiments, the cartridge 140 can be a prefilled syringe or the like.
In use, the delivery member 110 can be inserted into, for example, an ocular tissue such that at least a portion of the delivery member 110 is disposed within the sclera or suprachoroidal space of the eye. With the delivery member 110 disposed within the eye, the cartridge 140 can be moved within the inner volume of and/or relative to the cartridge housing 130 to place the inner volume of the cartridge 140 in fluid communication with the lumen defined by the delivery member 110. After the cartridge 140 is placed in fluid communication with the delivery member 110, the cartridge 140 can be moved from the first configuration to the second configuration to expel the drug formulation (contained within the inner volume) through the lumen of the delivery member 110. Thus, in this manner, the delivery device 100 can deliver a drug formulation to the suprachoroidal space of the eye and the drug formulation can flow within the suprachoroidal space to be delivered to, for example, the posterior region of the eye. In other embodiments, the delivery device 100 can deliver a drug formulation to any suitable location.
As shown in
The microneedle 210 can be any suitable device that is configured to puncture, a target tissue of a patient. For example, the microneedle 210 can be any of the microneedles described herein configured to puncture ocular tissue. In some embodiments, the microneedle 210 can be a 30 gauge microneedle, a 32 gauge microneedle or a 34 gauge microneedle. In some embodiments, the shape and/or size of the microneedle 210 can correspond with at least a portion of a target tissue. For example, in some embodiments, the length of the microneedle 210 can correspond with a portion of ocular tissue such that when the microneedle 210 is inserted into the ocular tissue, a portion of the microneedle 210 is disposed within the sclera or suprachoroidal space of the eye. In other embodiments, a bevel geometry (e.g., bevel angle, bevel height, bevel aspect ratio or the like) of the microneedle 210 is shaped such that the distal tip of the microneedle 210 can easily pierce the target tissue and the opening (not shown) of the microneedle 210 can be maintained within a desired region during an injection event.
The microneedle 210 defines a lumen 214 that extends through a proximal end portion 211 and a distal end portion 212 of the microneedle 210. The distal end portion 212 of the microneedle 210 can include a bevel or a sharpened tip configured to puncture, pierce and/or separate a target tissue of a patient (e.g., ocular tissue), as described in further detail herein. The proximal end portion 211 of the microneedle 210 is physically and fluidically coupled to the cartridge housing 230. In some embodiments, the microneedle 210 and the cartridge housing 230 can be monolithically or unitarily formed. In other embodiments, the microneedle 210 can be physically coupled to the cartridge housing 230 via a press fit, a friction fit, a threaded coupling, an adhesive, and/or any other suitable coupling means. In this manner, the lumen 214 defined by the microneedle 210 can be placed in fluid communication with an inner volume 233 defined by the cartridge housing 230, as described in further detail herein.
The cartridge housing 230 has a proximal end portion 231 and a distal end portion 232. The distal end portion 232 is physically and fluidically coupled to the microneedle 210, as described above. The proximal end portion 231 can be configured to receive and/or be coupled to the cartridge 240. More specifically, at least a portion of the cartridge 240 can be inserted through an opening 235 defined by the proximal end portion 231 of the cartridge housing 230 such that at least a portion of the cartridge 240 is disposed within the inner volume 233 of the cartridge housing 230.
The cartridge 240 includes a cartridge body 241 and a plunger 245. The cartridge body 241 has a proximal end portion 242 and a distal end portion 243 and defines an inner volume 244. The proximal end portion 242 of the cartridge body 241 is substantially open such that the cartridge body 241 can movably receive at least a portion of the plunger 245. More specifically, at least a portion of the plunger 245 is disposed within the inner volume 244 and can be moved between a first position (e.g., a proximal position) and a second position (e.g., a distal position). The plunger 245 includes a seal member 246 that forms a friction fit with one or more surfaces of the cartridge body 241 that define the inner volume 244. In this manner, the seal member 246 and the cartridge body 241 can form a substantially fluid-tight seal that substantially isolates a portion of the inner volume 244 that is distal to the seal member 246 from a portion of the inner volume 244 that is proximal to the seal member 246, as described in further detail herein.
In some embodiments, the distal end portion 243 of the cartridge body 241 can be at least temporarily closed (e.g., at least temporarily fluidically sealed). In this manner, the inner volume 244 (e.g., the portion of the inner volume 244 between the seal member 246 and the distal end portion 243) of the cartridge body 241 is fluidically isolated from a volume outside of the cartridge body 241. The inner volume 244 of the cartridge body 241 can further house or contain a drug formulation of the compositions described herein (e.g., a prophylactic agent, a therapeutic agent, or a diagnostic agent). More specifically, the drug formulation is disposed within the inner volume 244 of the cartridge body 241 in a distal position relative to the seal member 246. Thus, the drug formulation contained within the inner volume 244 is substantially fluidically isolated from a volume outside of the container body 241. In some embodiments, the inner volume 244 can contain a drug formulation with a volume of about 0.5 mL or less, for example about 0.1 mL to about 0.5 mL. In other embodiments, the inner volume 244 can contain a drug formulation with a volume of about 0.1 mL. In still other embodiments, the inner volume 244 can contain a drug formulation with a volume greater the about 0.5 mL.
In some embodiments, the distal end portion 243 of the cartridge body 241 can be moved between a first configuration (e.g., a closed or sealed configuration) and a second configuration (e.g., an open configuration). Expanding further, the distal end portion 243 of the container body 241 can include a surface that can be deformed (e.g., punctured, broken, opened, or otherwise reconfigured) to expel the drug formulation contained with the inner volume 244 of the cartridge body 241. For example, in some embodiments, the cartridge 240 can be inserted into the cartridge housing 230 such that the deformable surface of the distal end portion 243 of the cartridge body 241 is placed in contact with the proximal end portion 211 of the microneedle 210. In such embodiments, the proximal end portion 211 of the microneedle 210 can extend from a surface of the cartridge housing 230 that defines the inner volume 233 such that when the cartridge 240 is disposed within the inner volume 233, the proximal end portion of the microneedle 210 pierces, breaks, or otherwise reconfigures the deformable portion of the cartridge body 241. In this manner, the lumen 214 defined by the microneedle 210 can be placed in fluid communication with the inner volume 244 defined by the cartridge body 241. Therefore, when the plunger 245 is moved from its first position to its second position relative to the cartridge body 241, the drug formulation contained within the inner volume 244 of the cartridge body 241 can be expelled through the lumen 214 defined by the microneedle 210.
In other embodiments, however, the distal end portion 243 of the cartridge body 241 can be fluidically coupled to the microneedle 210. In this manner, the inner volume 244 (e.g., the portion of the inner volume 244 between the seal member 246 and the distal end portion 243) of the cartridge body 241 is fluidically coupled to a volume outside of the cartridge body 241 via the microneedle 210. For example, in some embodiments the distal end portion 243 can be devoid of a deformable portion or seal (e.g., a crimp seal), and in use the proximal end portion of the microneedle 210 need not pierce, break, or otherwise a surface prior to use.
In use, a user (e.g., a doctor, technician, nurse, physician, ophthalmologist, etc.) can remove the cap 250 to expose at least a portion of the microneedle 210 and can manipulate the infusion device 200 to insert the microneedle 210 into, for example, an ocular tissue. As described above, the length and/or the shape of the distal end portion 212 of the microneedle 210 (including, for example, a beveled surface) at least partially corresponds with the target tissue (e.g., the eye) such that the distal end portion 212 of the microneedle 210 is disposed within a lower portion of the sclera and/or the suprachoroidal space of the eye after being inserted. More specifically, the distal end portion 212 of the microneedle 210 is configured to pierce the sclera of the eye and be disposed within the sclera and/or suprachoroidal space without substantially piercing the choroid of the eye.
With the microneedle 210 disposed within the eye, the cartridge 240 can be moved within the inner volume 233 of the cartridge housing 230 to place the inner volume 244 of the cartridge body 241 in fluid communication with the lumen 214 defined by the microneedle 210. For example, in some embodiments, the proximal end portion 211 of the microneedle 210 can pierce or otherwise reconfigure the proximal end portion 211 to move the deformable surface from a sealed configuration to an unsealed or open configuration. Thus, the inner volume 244 of the cartridge body 241 is placed in fluid communication with the lumen 214 defined by the microneedle 210.
After the inner volume 244 of the cartridge body 241 is placed in fluid communication with the microneedle 210, the cartridge 240 can be moved from a first configuration (e.g., where the plunger 245 is disposed in its first position relative to the cartridge body 241) to a second configuration (e.g., where the plunger 245 is disposed in its second position relative to the cartridge body 241). With the seal member 246 forming a substantially fluid-tight or leak-proof seal (e.g., a substantially hermetic seal) with an inner surface of the cartridge body 241, the movement of the plunger 245 to its second position expels the drug formulation (contained within the inner volume 244) through the lumen 214 of the microneedle 210. Thus, the medicament delivery device 200 can deliver the drug formulation to the suprachoroidal space of the eye and the drug formulation can flow within the suprachoroidal space to be delivered to, for example, the posterior region of the eye.
Although the proximal end portion 211 of the microneedle 210 is described above as piercing or otherwise reconfiguring the deformable surface of the distal end portion 243 of the cartridge body 241, in other embodiments, the microneedle 210 need not physically contact the cartridge body 241. For example, in some embodiments, the distal end portion 243 of the cartridge body 241 can be in its closed configuration (e.g., undeformed configuration) when the plunger 245 is moved relative to the cartridge body 241. In such embodiments, the movement of the plunger 245 can increase the pressure within the inner volume 244 and the increase in pressure can move the deformable surface of the distal end portion 243 to its open configuration (e.g., deformed configuration). For example, the increase in pressure can open a valve or break (e.g., rupture) the deformable surface. Thus, the inner volume 244 can be placed in fluid communication with the lumen 214 of the microneedle 210 and the medicament delivery device 200 can deliver the drug formulation to the target tissue.
Although the microneedle 210 is described above as being inserted such that the distal end portion 212 is at least partially disposed in the suprachoroidal space, in other instances, the microneedle 210 can be inserted into various other regions of ocular tissue. For example, in some instances, a the microneedle 210 can be inserted through the ciliary body to dispose, at least partially, the distal end portion 212 of the microneedle 210 in the vitreous of, for example, a pediatric eye, as described in further detail herein.
Although not shown in
In other embodiments, the microneedle 310 can have a shaft length H′ suitable for use in treatment of other portions of the eye, such as, the vitreous. For example, in some embodiments, the microneedle 310 can have a shaft length H′ of about 1 mm to about 3 mm. In another embodiments, the microneedle 310 can have a shaft length H′ from about 2.5 mm to about 5.5 mm. In yet another embodiment, the microneedle 310 can have a shaft length H′ from about 3 mm to about 4 mm.
The walls 313 define a lumen 314 that extends through the proximal end portion 311 and the distal end portion 312. The proximal end portion 311 includes a base (or hub) 319 and/or can be coupled to (e.g., physically and/or fluidically) any suitable medical device. For example, in some embodiments, the proximal end portion 311 can be physically and fluidically coupled to the cartridge housing 230, as described above with reference to
The distal end portion 312 of the microneedle 310 defines an opening 315 configured to place the lumen 314 in fluid communication with a volume substantially outside the microneedle 310. The distal end portion 312 includes a bevel 316 (also referred to herein as “beveled surface”) with a distal edge 317 and a proximal edge 318. Similarly stated, the distal end portion 312 includes a surface (i.e., the bevel 316) that is slanted, sloped, angled and/or inclined from an outer surface of the walls 313. Said another way, the beveled surface 316 intersects the outer surface of the walls 313 at one or more angles to define one or more sharp edges (e.g., the distal edge 317 and/or the proximal edge 318), as defined herein. This arrangement allows the distal end portion 312 of the microneedle to pierce, separate and/or deform the target tissue to facilitate penetration of the shaft microneedle 310 therethrough. Similarly stated, the sharp distal edge 317 is configured to pierce the target tissue, such as ocular tissue, to facilitate defining a passageway within the target tissue to the desired location (e.g., the suprachoroidal space and/or the vitreous, as described in further detail herein).
As shown in
For example, in some embodiments, the height H1 and/or H′1 of the bevel 316 can be about 500 μm or less, about 450 μm or less, about 400 μm or less, about 350 μm or less, about 300 μm or less, about 250 μm or less, about 200 μm or less, about 150 μm or less, or about 100 μm or less. In other embodiments, the height H1 and/or H′1 of the bevel 316 is from about 50 μm to about 500 μm, from about 100 μm to about 500 μm, from about 150 μm to about 500 μm, from about 200 μm to about 500 μm, from about 250 μm to about 500 μm, from about 300 μm to about 500 μm, from about 50 μm to about 400 μm, from about 100 μm to about 400 μm, or from about 150 μm to about 400 μm. In some embodiments, the height H1 and/or H′1 of the bevel 316 can be about 485 μm. In still other embodiments, the height H1 and/or H′1 of the bevel 316 can be about 500 μm to about 1 mm. In another embodiment, the height H1 and/or H′1 of the bevel 316 is from about 600 μm to about 1 mm, from about 700 μm to about 1 mm, from about 800 μm to about 1 mm, from about 900 μm to about 1 mm, and/or any fraction there between.
While characterized above by the height H1 and/or H′1 of the bevel 316, in other embodiments, the microneedle 310 can be characterized by a bevel angle, or more particularly, a tip angle relative to an axis defined by the lumen 314. In some embodiments, the tip angle can be selected to facilitate insertion of the microneedle 310 within the desired type of tissue (e.g., ocular tissue). Similarly stated, in some embodiments, the tip angle can be selected to provide a sufficient “sharpness” such that the microneedle 310 can be inserted into the eye (e.g., the sclera) while minimizing the deformation of the eye resulting from the force of insertion. For example, in some embodiments, the bevel angle can be less than about 0.1 degree. In other embodiments, the bevel angle can be from approximately 0.1 degree to approximately 1 degree. In still other embodiments, the bevel angle can be from approximately 1 degree to approximately 5 degrees, including any fraction of a degree there between. In some embodiments, the microneedle 310 has a bevel angle from about 0.1 degree to about 30 degrees or from about 1 degree to about 25 degrees or from about 2 degrees to about 20 degrees or from about 10 degrees to about 20 degrees. In some embodiments, the tip angle can be less than about 18 degrees, 15 degrees or 12 degrees.
In yet other embodiments, the microneedle 310 can be characterized by the bevel height H1 (or H′1) to width W1 ratio, (i.e., the bevel aspect ratio). In some embodiments, the bevel width W1 corresponds with an outer diameter of the microneedle 310. In other embodiments, the bevel width W1 can be associated with a diameter that is smaller than the outer diameter of the microneedle 310 (e.g., the microneedle 310 can have an outer diameter that is tapered from the proximal end portion 311 to the distal end portion 3212). In some embodiments, the bevel width W1 is from about 50 μm to about 500 μm, from about 50 μm to about 400 μm, from about 100 μm to about 400 μm, from about 200 μm to about 400 μm, from about 200 μm to about 320 μm, or from about 100 μm to about 250 μm. As such, the microneedle 310 can have a bevel aspect ratio (height:width) is about 0.25:1, about 0.5:1, about 0.75:1, about 1:1, about 1.5:1, about 2:1, about 2.2:1, about 2.5:1 or about 3:1.
In this manner, the arrangement of the bevel 316 (e.g., the bevel can be such that the distal edge 317 is sufficiently sharp such as to pierce a target tissue and penetrate into sclera, the suprachoroidal space or the vitreous without (I) substantially causing the target tissue to elastically deform or (ii) damaging internal structures of the eye (e.g., the lens, retina, choroid, etc.). Similarly stated, the arrangement of the bevel 316 can be such that the distal edge 317 is sufficiently sharp such that prior to piercing the target tissue, the distal edge 317 does not substantially bend, compress, deform, or otherwise move the target tissue. Thus, the accuracy of insertion relative to the target tissue is increased and a potential for damaging surrounding tissue is minimized.
As described above, the microneedle 310 has a shaft length H′. The shaft length H′ of the microneedle 310 is defined as the length from the distal edge 317 to the hub or base surface 319. In the drug delivery methods provided herein, the entire shaft length H′ or substantially the entire shaft length H′ of the microneedle 310 can be inserted into the eye. In this regard, the user need not determine the depth of insertion. The shaft length H′ is such that when the microneedle 310 inserted through, for example, the ciliary body, the risk of piercing the lens or retina is greatly minimized or eliminated. Similarly, the shaft length H′ is such that when the microneedle 310 is inserted through the sclera at about the ocular hemisphere (described above), the risk of piercing the choroid and/or retina is greatly minimized or eliminated. In this regard, the microneedles provided herein achieve greater reproducibility, and eliminate or substantially reduce uncertainty associated with drug delivery methods to the eye (e.g., to the suprachoroidal space and/or to the vitreous). The shaft length can be tailored depending on the age of the patient and the desired tissue for drug delivery or aspiration.
While the bevel 316 included in the microneedle 310 is shown in
The walls 413 of the microneedle 410 define a lumen 414 extending through the proximal end portion 411 and the distal end portion 412. Furthermore, the walls 413 can have and/or can define a width W2 associated with an outer diameter and/or a beveled surface 416 of the microneedle 410, as described in further detail herein. The proximal end portion 411 can be substantially similar in form and function as the proximal end portion 311 included in the microneedle 310 described above with reference to
As shown
In some embodiments, the height H2 of the bevel can be about 500 μm to about 1 mm. In another embodiment, the height H2 of the bevel 416 is about 500 μm or less, about 450 μm or less, about 400 μm or less, about 350 μm or less, about 300 μm or less, about 250 μm or less, about 200 μm or less, about 150 μm or less, or about 100 μm or less. In other embodiments, the height H2 of the bevel 416 is from about 50 μm to about 500 μm, from about 100 μm to about 500 μm, from about 150 μm to about 500 μm, from about 200 μm to about 500 μm, from about 250 μm to about 500 μm, from about 300 μm to about 500 μm, from about 50 μm to about 400 μm, from about 100 μm to about 400 μm, or from about 150 μm to about 400 μm. The bevel height H2 can be any bevel height that prevents piercing of the lens, retina, or choroid when the distal end 412 of the microneedle 410 is inserted through the sclera, and the entire shaft length H″ or substantially the entire shaft length H″ of the microneedle 410 is inserted into the eye.
As described above, the microneedle 410 has the width W2. In some embodiments, the width W2 can be from about 50 μm to about 500 μm, from about 50 μm to about 400 μm, from about 100 μm to about 400 μm, from about 200 μm to about 400 μm, or from about 100 μm to about 250 μm. In some embodiments, the microneedle 410 can be characterized by, for example, a bevel height H2 to width W2 ratio (i.e., a bevel aspect ratio (height:width)). In some embodiments, the microneedle 410 can have a bevel aspect ratio that is about 0.25:1, about 0.5:1, about 0.75:1, about 1:1, about 1.5:1, about 2:1, about 2.2:1, about 2.5:1, or about 3:1. In some embodiments, the microneedle 410 can have a bevel aspect ratio that is less than about 3.0:1, about 2.5:1, about 2.2:1, about 2.0:1 or about 1.5:1.
As shown in
In some embodiments, the second bevel angle Θ2 can be from about 20 degrees to about 30 degrees, or from about 20 degrees to about 45 degrees, or from about 20 degrees to about 60 degrees, or from about 20 degrees to about 75 degrees, or from about 20 degrees to about 90 degrees. In other embodiments, the second bevel angle Θ2 can be less than 20 degrees yet still larger than the first bevel angle Θ1. In some embodiments, the second bevel angle Θ2 can be greater than about 30 degrees. In some embodiments, the second bevel angle Θ2 can be between about 30 degrees and about 45 degrees. In other embodiments, the second bevel angle Θ2 can be between about 45 degrees and about 90 degrees.
As a result, arrangement of the bevel 416 at or near the distal edge 417 can define a radius of curvature that is substantially larger than the arrangement of the bevel 416 at or near the proximal edge 418. In this manner, the bevel 416 and more particularly, the distal edge 417, can be sufficiently sharp (as described above), while the second portion of the bevel 417 can be configured to maintain the structural rigidity of the distal end portion 412 of the microneedle 410 and/or maintain the bevel height H2 at or below a desired value. For example, the first bevel angle Θ1 can be below a desired angle such that a thickness of the first portion 420 of the walls 413 is sufficiently thin to pierce ocular tissue without substantially bending, curving, deforming, and/or otherwise moving the ocular tissue prior to insertion. Conversely, the second bevel angle Θ2 can be increased (e.g., relative to the first bevel angle Θ1) to an extent such that a thickness of the second portion 421 of the walls 413 is sufficiently thick to maintain the structural rigidity of the distal end portion 412 of the microneedle 410 and/or such that the bevel height H2 is at or below a desired value.
As shown in
Although the microneedle 410 is shown in
In some embodiments, the distal end portion 512 of the microneedle 510 can be cut or formed in a plane that is different from (e.g., substantially orthogonal to) the plane in which the bevel 516 is profiled (e.g., as shown in
While the bevels 416 and 516 are shown as forming a substantially smooth curve or continuous surface, in other embodiments, a microneedle can include a bevel that is formed from any number of planes or segments (e.g., a three facet or a four facet bevel). For example,
The walls 613 define a lumen 614 extending through the proximal end portion 611 and the distal end portion 612. The proximal end portion 611 can be substantially similar in form and function as the proximal end portion 311 included in the microneedle 310 described above with reference to
The distal end portion 612 of the microneedle 610 includes a bevel or beveled surface 616 having a distal edge 617 and a proximal edge 618. Similarly stated, the distal end portion 612 includes a surface (i.e., the bevel 316) that is slanted, sloped, angled and/or inclined from an outer surface of the walls 613. Said another way, the beveled surface 616 intersects the outer surface of the walls 613 at one or more angles to define one or more sharp edges (e.g., the distal edge 617 and/or the proximal edge 618), as defined herein. This arrangement allows the distal end portion 612 of the microneedle to pierce, separate and/or deform the target tissue to facilitate penetration of the shaft microneedle 610 therethrough. Similarly stated, the sharp distal edge 617 is configured to pierce the target tissue, such as ocular tissue, to facilitate defining a passageway within the target tissue to the desired location (e.g., the suprachoroidal space and/or the vitreous, as described herein).
While not shown in
In some embodiments, the microneedle 610 comprises multiple facets (also referred to as segments). For example, as shown in
In some embodiments, the segments X1, X2, X3, and X4 can be substantially similar in length to each other. In other embodiments, the segments X1, X2, X3, and X4 can be substantially different lengths. Furthermore, the segments X1, X2, X3, and X4 can be configured to be substantially tangential to a radius of curvature (not shown) of the bevel 616. Therefore, as shown in
In some embodiments, the first segment X1 defines a first bevel angle Θ′1 (e.g., a tip angle or distal angle) and another segment (e.g., segment X4) defines a second bevel angle Θ′2 (e.g., a proximal angle or an inside angle). In some embodiments, the first bevel angle Θ′1 can be smaller than the second bevel angle Θ′2. For example, in some embodiments, the first bevel angle Θ′1 and/or the second bevel angle Θ′2 can be any angle or within any range of angles described above with reference to the microneedle 410. As a result, arrangement of the bevel 616 at or near the distal edge 617 can be sufficiently sharp (as described herein), while the portion of the bevel 617 at or near the proximal edge 618 can be configured to maintain the structural rigidity of the microneedle 610 and/or maintain the bevel height H3 at or below a desired value. For example, the first bevel angle Θ′1 can be such that a thickness of a first portion of the walls 613 is sufficiently thin to pierce ocular tissue without substantially bending, curving, deforming, and/or otherwise moving the ocular tissue prior to insertion. Conversely, the second bevel angle Θ′2 can be larger than the first bevel angle Θ′1 to maintain the bevel height H3 and/or the bevel aspect ratio (H3:W3) at or below any of the values specified herein.
In this manner, the height H3 can be such that when the microneedle is disposed within the sclera, the opening (not shown in

In some embodiments, the microneedle can have a shaft length (not identified in
The walls 713 define a lumen 714 extending through the proximal end portion 711 and the distal end portion 712. The walls 713 have a thickness t1 and define an outer diameter d1 of the microneedle 710 and an inner diameter d2 of the microneedle 710. In some embodiments, the outer diameter d1 of the microneedle 710 is 30 gauge, 32 gauge, 34 gauge or 36 gauge. In some embodiments, the outer diameter d1 can be from about 50 μm to about 500 μm, from about 50 μm to about 400 μm, from about 100 μm to about 400 μm, from about 200 μm to about 400 μm, or from about 100 μm to about 250 μm. In some embodiments, the inner diameter d2 can be at least partially associated with a particle size of a drug to be conveyed therethrough. For example, in some embodiments, the inner diameter d2 can be about 5 times the average particle size of a drug that is to be conveyed therethrough. In some embodiments, the inner diameter d2 can be between about 100 μm and about 130 μm. In other embodiments, the inner diameter d2 can be between about 110 μm and about 120 μm. In still other embodiments, the inner diameter d2 can be less than 100 μm. In yet other embodiments, the inner diameter d2 can be greater than 130 μm. The opening 715 defined by the distal end portion 712 has a diameter d3 that is configured to be substantially greater than the inner diameter d2 and substantially less than the outer diameter d1.
While the bevel 716 is shown in
The walls 813 define a lumen 814 extending through the proximal end portion 811 and the distal end portion 812. The walls 813 have a thickness t1 and define an outer diameter d1 of the microneedle 810 and an inner diameter d2 of the microneedle 810. In some embodiments, the outer diameter d1 of the microneedle 810 is 30 gauge, 32 gauge, 34 gauge or 36 gauge. The opening 815 defined by the curvilinear bevel 816 has a length l1 that is configured to be greater than the inner diameter d2 and less than the outer diameter d1.

In some embodiments, a method of delivering a drug formulation to target ocular tissue includes inserting the microneedle 1010 into the sclera 20 of the eye 10 and advancing the microneedle 1010 through the sclera 20 such that the entire or substantially the entire shaft length (H′ or H″) of the microneedle 1010 between a proximal end portion 1011 and a distal end portion 1012 is disposed in the eye 10 (as shown in
As shown in
Moreover, the distal end portion 1012 of the microneedle 1010 includes a beveled surface, which can be similar to any of the beveled surfaces described herein. In particular, the beveled surface is configured such that the distal end opening (not identified) of the microneedle 1010 is at a desired location of the sclera 20 and/or suprachoroidal space 36. Thus, in some embodiments, the bevel height and/or the bevel aspect ratio is such that when the distal edge 1017 is disposed within the suprachoroidal space and/or adjacent the choroid, the opening does not extend outside of the lower portion 20a of the sclera 20. The lower portion 20a of the sclera 20 can include the lower half of the sclera 20, third of the sclera 20, or quarter of the sclera 20. More particularly, because the microneedle 1010 can be inserted into the ocular tissue at an angle that is between about 80 degrees and about 100 degrees relative to a tangential surface of the insertion site of the eye, the circumferential angular orientation (i.e., the angle of rotation about the axis of the microneedle) need not be controlled.
With the distal end portion 1012 of the microneedle 1010 disposed in the lower portion 20a of the sclera 20 and/or the suprachoroidal space 36, in one embodiment, the method further includes delivering a drug formulation through a lumen 1014 defined by the microneedle 1010 and into the lower portion 20a of the sclera 20 and/or the suprachoroidal space 36. More specifically, with the distal end portion 1012 of the microneedle 1010 disposed in the lower portion 20a of the sclera and/or the suprachoroidal space 36, the cartridge 1040 can be moved within the cartridge housing 1030, as described in detail with reference to
With the distal end portion 1012 of the microneedle 1010 disposed within the lower portion 20a of the sclera 20 and/or the suprachoroidal space 36, the drug formulation can be expelled from the lumen 1014 of the microneedle 1010 to substantially expand a volume of the suprachoroidal space 36, as described above. In this manner, the drug can flow circumferentially within the suprachoroidal space 36 to be delivered to, for example, the posterior region of the eye 10, as indicated by the arrows CC in
Although
Some of the microneedles and methods described herein can be used to deliver a drug to the suprachoroidal space of the eye. Injection may be performed by inserting the microneedle anterior to, at, or posterior to, the equator of the eye. For example, in some embodiments, the microneedle is inserted approximately 0.3 mm to 0.6 mm posterior to the limbus. In the methods provided herein, the entire shaft of the microneedle or substantially the entire shaft of the microneedle is inserted into the eye without damaging the retina or lens.
In some embodiments, the eye is a pediatric eye. In the methods described herein, the entire microneedle shaft length or substantially the entire microneedle shaft length (H′ or H″, see

Provided herein are methods for treating retinoblastoma in a patient in need thereof, and in particular, a pediatric patient in need thereof. Retinoblastoma is one of the most common primary intraocular tumor in children and one of the five most common childhood cancers. There is approximately 1 child born with retinoblastoma in 18,000 live births in the United States. A retinoblastoma tumor may be heritable and bilateral, resulting from a second mutation in developing retinal cells in an infant who harbors a germline mutation in the retinoblastoma gene. The tumor may grow within the retina and develop neovascularization, extending toward the vitreous (endophytic growth pattern), toward the choroid (exophytic growth pattern), a combination of both, or diffusely infiltrate the retina. Retinoblastoma often forms spheroids of tumor and invades the avascular vitreous, in a process known as vitreous seeding. Therefore, a type of therapy which will locally deliver chemotherapeutic agents, including to vitreous tumor seeds, is desirable.
Intra-arterial chemotherapy (IAC) has been utilized via radiologic guided trans-arterial cannulization of the ophthalmic artery. More recently, trans-arterial chemotherapy of retinoblastoma using a microcatheter has been employed; however, this method requires multiple injections and is associated with risks such as stroke. Moreover, the technique has been shown to be ineffective in approximately ⅓ of cases. Reasons for failure of chemoreduction and IAC include most importantly failure to control vitreous seeds, followed by resistant well differentiated tumor, intraretinal tumor and subretinal tumor. Although a recent preliminary study showed evidence of retinoblastoma tumor control, including control of vitreous seeds with intravitreal injections of methotrexate using a 30 gauge needle, there are risks of seeding the tumor when utilizing a 30 gauge needle (Kivela et al. Intravitreal methotrexate for retinoblastoma. Ophthalmology 2011; 118, 1689-6; Karcioglu et al. Tumor seeding in ocular fine needle aspiration biopsy. Ophthalmology 1985; 92, 1763-1767). Accordingly, a local delivery method that reduces or eliminates the risks of tumor seeding is desirable in the field of retinoblastoma treatment and therapy.
In some embodiments, a method for treating retinoblastoma is provided, comprising inserting at least one microneedle into the vitreous of the eye of the patient (e.g., a pediatric patient), and delivering, injecting and/or infusing a drug formulation into the vitreous of the eye through the microneedle. In a further embodiment, the drug formulation comprises an effective amount of a topoisomerase inhibitor, e.g., topotecan. Any of the microneedle embodiments described herein can be configured to deliver an effective amount of a suitable medicament for the treatment of retinoblastoma, or other ocular cancer. For example, any of the embodiments described herein can deliver vincristine, paclitaxel, cisplatin, carboplatin, teniposide, etoposide, cyclophosphamide, ifosfamide, doxorubicin, idrubicin, topotecan, and/or any other suitable medicament. In one embodiment, topotecan is delivered to the vitreous with one of the methods described herein. In some instances, the patient is a pediatric patient.
In one embodiment, provided herein are methods for decreasing the size of an intraocular retinoblastoma tumor. In one embodiment, the method comprises infusing an effective amount of topotecan into an eye of the patient, wherein the eye comprises one or more retinoblastoma tumors, and the effective amount of topotecan is infused into the vitreous through the at least one microneedle. In a further embodiment, the patient is a pediatric patient. In one embodiment, the drug is infused into the vitreous according to an hourly, daily, or weekly dosing regimen. In one embodiment, the drug is infused into the eye once weekly. In a further embodiment, the drug is infused into the eye once weekly for two, three, four, five, or six weeks. In a further embodiment, the drug is infused into the eye once weekly for three weeks.
The dosage of topotecan can vary, as appreciated by those of skill in the art. For example, in one embodiment, the topotecan is administered at a dose of between about 1 μg/50 μL and about 100 μg/50 μL per dose. In a further embodiment, topotecan is administered at a dosage of about 1 μg, about 5 μg, about 10 μg, about 20 μg, about 50 μg, about 75 μg, or about 100 μg. In a further embodiment, topotecan is administered at a dose of about 10 μg. In one embodiment, when the microneedle is used to infuse topotecan, the tumor area is reduced to a greater extent in comparison to the reduction in tumor area that occurs when the same dosage and dosing regimen of topotecan is infused into the vitreous using a 30 gauge needle.
In another embodiment, when the microneedle is used to infuse topotecan or other chemotherapeutic agent, the number of vitreous tumor seeds is reduced to a greater extent compared to the reduction in the number of vitreous tumor seeds that are present after infusion of topotecan using a 30 gauge needle under the same dosing regimen.
In one embodiment, the method comprises inserting a microneedle through the ciliary body of the pediatric eye wherein the entire shaft or substantially the entire shaft of the microneedle is inserted into the eye, and infusing a drug into the vitreous. In a further embodiment, the eye is a pediatric eye.
For example, in one embodiment, a method for treating an intraocular tumor in a child is provided (see
In this manner, the arrangement of any of the embodiments described above with reference to
In some embodiments, the microneedle 1110 is configured such that the tract produced by the insertion of the microneedle 1110 is sufficiently small so that tumor (e.g., retinoblastoma) seeds within the vitreous 30 cannot substantially move within the tract. Therefore, the risk of seeding (e.g., spreading) the tumor is greatly reduced if not eliminated all together. Furthermore, the microneedle 1110 is fabricated such that the amount of damage to surrounding tissue (e.g., the lens 18 or retina 34) due to the insertion of the microneedle 1110 is substantially reduced or eliminated. For example, in some embodiments, the microneedle 1110 can include a bevel of the types shown and described herein, which can contribute to and/or result in a reduced needle tract.

While the embodiments and methods herein describe delivering a medicament to a target tissue, in other embodiments, the embodiments described herein can be configured to facilitate a biopsy or other aspiration procedure. Some biopsy techniques include creation of a scleral flap and suturing of the scleral flap, two procedures that put the eye at risk for perforation and tumor seeding. In some instances, fine needle aspiration biopsy of the tumor with commercially available 27 and 30 gauge needles and methods can still result in tumor seeding. This tumor seeding increases the risk for metastasis and mortality from the tumor. Therefore, in some instances, a microneedle can be inserted into the eye in order to extract a biological tissue, fluid, or molecule from the sclera or corneal stroma.
In other instances, a microneedle can be inserted into the vitreous of an eye to core a target tissue such as, for example, a tumor. In some instances, the tumor is a retinoblastoma. The arrangement of the embodiments described herein can be such that the extraction of the biological tissue, fluid, or molecule sample results in less accumulation of the biological tissue, fluid, or molecule in comparison to the accumulation of the biological tissue, fluid, or molecule in the needle tract that occurs following a extraction of a biological tissue, fluid, or molecule sample using a 30 gauge needle. For example, in some embodiments, a retinoblastoma is extracted from an eye and less retinoblastoma seeds accumulate in the needle tract in comparison to extraction of retinoblastoma using a 30 gauge needle. In one embodiment, retinoblastoma cells are not present in the needle tract following extraction of a retinoblastoma tumor, or portion thereof, using one of the microneedles described herein.
Any of the embodiments described herein can be used in any suitable system and/or with any suitable method for administration of a fluid drug formulation to, or withdrawal of fluid from, one or more biological tissues. For example,
As shown, in some embodiments, the inner volume 1233 can include two fluid drug formulations 1238 and 1239 for injection into the eye. Although not shown, in other embodiments, more than two or less than two fluid drug formulations can be disposed in the inner volume 1233. In some instances, the first fluid drug formulation 1238 can have a different viscosity than the second fluid drug formulation 1239, such that the fluid drug formulations can be injected in series through the lumen 1214 and out the opening 1215 of the microneedle into the biological tissue. In one embodiment, the first fluid drug formulation 1238 has a greater viscosity than that of the second fluid drug formulation 1239 such that the second fluid drug formulation 1239 facilitates delivery of the first fluid drug formulation 1238 to the target biological tissue.
Any of the embodiments described herein can be included in any suitable infusion and/or aspiration system. For example,
The pressure feedback control systems 1360 can be used to monitor and control the pressure being applied to the drug housing 1330 during the insertion process, thereby monitoring and controlling the position of the microneedle 1310 in the biological tissue. In one embodiment, the pressure feedback control system 1360 is used to monitor and control the pressure being applied to the plunger 1345 during the injection process. In another embodiment, the pressure feedback control system 1360 is used for combinations of the foregoing. For example, injection into the suprachoroidal space generally requires a lower pressure than injection into the sclera. Thus, the pressure feedback control system 1360 can be utilized to facilitate placement of the microneedle 1310 and injection of the fluid drug formulation into the desired target biological tissue (e.g., by injecting some nominal amount of fluid to determine the position and proper placement of the microneedle).
Although not shown, any other type of control system or combination thereof can be used to control the transport of drug formulation or biological fluid through the hollow microneedle 1310. For instance, in one embodiment, the system 1360 can include a micropump, a microvalve, and a positioner, with a microprocessor programmed to control a pump or valve to control the rate of delivery of a drug formulation through the microneedle 1310 and into the ocular tissue. The flow through a microneedle 1310 may be driven by diffusion, capillary action, mechanical displacement, electrosmosis, electrophoresis, convection, or other driving forces. Devices and microneedle designs can be tailored using known pumps and other devices to utilize these drivers. In one embodiment, the system 1360 can further include an iontophoretic apparatus, similar to that described in U.S. Pat. No. 6,319,240 to Beck (the disclosure of which is incorporated herein by reference in its entirety), for enhancing the delivery of the drug formulation to the ocular tissue. In another embodiment, the system 1360 can further include a flowmeter or other means to monitor flow through the microneedle 1310 and to coordinate use of the pumps and valves.
The flow of drug formulation or biological fluid can be regulated using various valves or gates known in the art. The valve may be one which can be selectively and repeatedly opened and closed, or it may be a single-use type, such as a fracturable barrier. Other valves or gates used in the system 1360 can be activated thermally, electrochemically, mechanically, or magnetically to selectively initiate, modulate, or stop the flow of material through the microneedle 1310. In one embodiment, the flow is controlled with a rate-limiting membrane acting as the valve.
Any of the embodiments described herein can be included in any suitable kit and/or packaging. In some embodiments, portions of a kit can be packaged together or separately. For example,
In some embodiments, any number of microneedles can be stored in, for example, an array or the like. For example,
Any of the embodiments described herein can be used in any suitable method for administering a drug into an eye of a patient. In some embodiments, a method can include inserting a microneedle into an outer tissue of the eye and a inserting a fluid drug formulation through the channel of the microneedle and into the outer tissue of the eye. The outer tissue includes but is not limited to the sclera, cornea, corneal stroma, choroid, suprachoroidal space, conjunctiva, subconjunctival space, and subretinal space. The microneedle systems can also be used to deliver drug to tissues and sites proximal to the outer tissue, including trabecular meshwork, ciliary body, aqueous humour or vitreous humour. In some embodiments, the fluid drug formulation released from the microneedle into the outer tissue subsequently spreads to one or more tissues proximal to the outer tissue. For example, the fluid drug formulation may subsequently spread to the trabecular meshwork, the inter photo receptor space between the rod and cone outer segments and/or the pigment epithelium, the aqueous humour or vitreous humour, or the ciliary muscle. As used herein, the term “spread” refers to transport or movement of the fluid away from the initial site of injection, where the movement may occur due to one or more forces, including diffusion. In other embodiments, the fluid drug formulation remains substantially at the site of injection and does not substantially spread to other tissues at the time of injection. In such embodiments, there may be subsequent movement of the drug from the site of injection after the injection.
In some embodiments, a method can further include using a pressure-guided feedback system to determine the location of the opening of the microneedle in the eye and/or for controlling the fluid drug formulation infusion. For example, the method can include a pressure-guided feedback system including measuring (i) the pressure applied to the microneedle during its insertion into the eye and/or (ii) the pressure of the fluid drug formulation during its infusion into the sclera, cornea, corneal stroma, choroid, suprachoroidal space, conjunctiva, or subretinal space. In an embodiment, a drop in the pressure resisting infusion of the fluid drug formulation is used to signal that the microneedle is inserted an amount effective to place the opening of the microneedle in fluid communication with the suprachoroidal space.
In another aspect, a method can include aspirating a fluid from an eye of a patient. The method can include inserting at least one hollow microneedle into the tissue of the eye at an insertion site, and aspirating fluid from the insertion site into the at least one microneedle. For example, the at least one hollow microneedle may be inserted into the sclera of the eye at an insertion site to remove fluid from the suprachoroidal space. Aspiration of fluid from the eye can be particularly advantageous prior to surgical intervention to determine appropriate therapeutic treatment. For example, in an embodiment the aspiration and analysis of fluid from the suprachoroidal space of a patient may be desirable prior to conducting retinal reattachment surgery to identify appropriate cytokine and/or inflammatory mediators for individual treatment prior to reattachment of the retina. As another example, the at least one hollow microneedle can be inserted into the cornea of the eye at an insertion site to remove fluid from the cornea and/or from the anterior chamber.
As described above with reference to the microneedles 410, 610 and 1010, the beveled surface can have a height such that when the microneedle is inserted into the eye, the beveled surface is within at least one of a suprachoroidal space or a lower portion of the sclera (see e.g.,
With the proximal end portion of the microneedle operably coupled to, for example, a medicament delivery device, a substance is conveyed from a cartridge coupled to the proximal end portion of the microneedle and into the suprachoroidal space via the opening defined by the beveled surface, at 1692. More specifically, the cartridge (e.g., the cartridge 240 included in the medicament delivery device 200 of
The embodiments described herein are further illustrated by reference to the following examples. However, it should be noted that these examples, like the embodiments described above, are illustrative and are not to be construed as restricting the scope of the embodiments in any way.
The delivery of substances to the eye and the inhibition of the growth of retinoblastoma cells using the microneedles described herein compared to standard needles was evaluated.
Human cadaver eyes were used to compare 30 gauge standard needle (
The number of cells that are allowed passage and that survived with the use of 34 gauge microneedles, in comparison to 26 or 30 gauge standard needles, was assessed. WERI human retinoblastoma (WERI-Rb) cells were aspirated and injected into culture media. At days 0, 2, 4, 6, 8, and 10 after aspiration and re-plating, the WERI-Rb cells that were viable were counted in triplicate. As shown in
The baffle 1876 was inserted into the microneedle 1810, which allows for drug to pass through via the channels present in the baffle 1876. In order to assess the spread of retinoblastoma cells from needles, human WERI-Rb cells were aspirated and re-plated into 96 well plates using a standard 34 gauge, a standard 34 gauge with a baffle, the microneedle 1710, and the microneedle 1810 with the baffle 1876. The least amount of retinoblastoma cell growth occurred with the microneedle 1810 with the baffle 1876, followed by the 34 gauge needle with baffle, the microneedle 1710, and finally the 34 gauge needle (
An experiment was conducted in order to assess whether microneedles are suitable for targeted drug delivery to vitreous seeds in a rabbit retinoblastoma model. New Zealand white rabbits received subretinal injections of retinoblastoma cells, which resulted in the establishment of tumors in the subretinal space near the optic nerve and in the vitreous (Kang and Grossniklaus, J Biomed Biotech 2011, Article ID 394730). In this model, similar to human retinoblastoma, vitreous seeds of viable tumor are present (indicated in
Either a 30 gauge needle or a microneedle with baffle was used to aspirate retinoblastoma tumors in enucleated eyes. An enucleated eye and a schematic depiction of the 30 gauge needle and the microneedle are shown in the left panel of
Following aspiration, enucleated eyes were prepared and sectioned, and sections were stained with hematoxylin-eosin. As shown in
New Zealand white rabbits received subretinal injections of retinoblastoma cells in order to establish tumors in the subretinal space near the optic nerve and in the vitreous space, as described above in Example 3. Fifty μL of PBS (control), 5 μg/50 uL of topotecan (“low dose”), or 10 μg/50 uL of topotecan (“high dose”) were injected once weekly for three weeks into the eye. Injections were conducted via insertion of a microneedle at the pars plana up to the microneedle hub.
In order to enumerate vitreous seeds before and after topotecan treatment, fundus examination was conducted just prior to the first injection and one week after the third injection. Vitreous seeds were graded as a 1 plus (+) if seeds filled less than one third of the vitreous; 2 plus (++) if seeds filled one third to two thirds of the vitreous; and 3 plus (+++) if seeds filled the entire vitreous (i.e., two thirds of the vitreous up to the entire vitreous). Scores of +, ++, and +++ were expressed as scores of 1, 2, and 3, respectively, and the scores for rabbits in each group were averaged. As shown in
One week after the third injection of topotecan, animals were euthanized and eyes were removed. All enucleated eyes were fixed in 10% formalin, dehydrated in increasing concentrations of alcohol, and cleared in xylene. Serial sections of 8 microns were prepared, and every third slide was stained with hematoxylin-eosin. Five sections with the largest tumor area in each eye were photographed at 40× magnification (DP10; Olympus, Tokyo, Japan). Tumor size was determined with ImageJ software (developed by Wayne Rasband, National Institutes of Health, Bethesda, Md.) and expressed as tumor area in mm2. As shown in
Although the embodiments have been described above as being used with a given set of drug formulations to treat specific ocular diseases, the embodiments described herein can be used with any suitable drug formulation to treat any suitable ocular disease. Non-limiting examples of ocular diseases include uveitis, glaucoma, diabetic macular edema or retinopathy, macular degeneration, retinoblastoma, and genetic diseases. The methods described herein are particularly useful for the local delivery of drugs that need to be administered to the posterior region of the eye, for example the retinochoroidal tissue, macula, and optic nerve in the posterior segment of the eye. In one embodiment, the delivery methods and devices described herein may be used in gene-based therapy applications. For example, the methods may administer a fluid drug formulation into the suprachoroidal space to deliver select DNA, RNA, or oligonucleotides to targeted ocular tissues.
The microneedles can be used to target delivery to specific tissues or regions within the eye or in neighboring tissue. In various embodiments, the methods may be designed for drug delivery specifically to the sclera, the choroid, the Brach's membrane, the retinal pigment epithelium, the subretinal space, the retina, the macula, the optic disk, the optic nerve, the ciliary body, the trabecular meshwork, the aqueous humor, the vitreous humor, and other ocular tissue or neighboring tissue in need of treatment.
A wide range of drugs may be formulated for delivery to ocular tissues with the present microneedle devices and methods. Moreover, any of the delivery devices and/or methods described herein can involve, include and/or contain any of the drugs described herein. For example, in some embodiments, the cartridge 240 or any other cartridge or medicament container described herein can contain any of the drugs and/or formulations described herein. As used herein, the term “drug” refers to any prophylactic, therapeutic, or diagnostic agent (e.g., a contrast agent). The drug may be selected from suitable proteins, peptides and fragments thereof, which can be naturally occurring, synthesized or recombinantly produced. Representative examples of types of drugs for delivery to ocular tissues include antibodies, anti-viral agents, chemotherapeutic agents (e.g., topoisomerase inhibitors), analgesics, anesthetics, aptamers, antihistamines, anti-inflammatory agents, and anti-neoplastic agents. In one embodiment, the drug is triamcinolone or triamcinolone acetonide.
The term “antibody” is intended to refer broadly to any immunologic binding agent such as IgG, IgM, IgA, IgD and IgE. An antibody can be monoclonal or polyclonal, and in one embodiment, is a humanized antibody. The term “antibody” is also used to refer to any antibody-like molecule that has an antigen binding region, and includes antibody fragments such as Fab′, Fab, F(ab′)2, single domain antibodies (DABs), Fv, scFv (single chain Fv), and engineering multivalent antibody fragments such as dibodies, tribodies and multibodies. The techniques for preparing and using various antibody-based constructs and fragments are well known in the art (see, e.g., Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory, 1988; incorporated herein by reference).

Accordingly, the methods of the present invention include administrating via IVT one or more of the drugs listed above in combination with one or more drugs disclosed herein administered into the suprachoroidal space using the microneedle device described herein.
In one embodiment, the drug is formulated for storage and delivery via the microneedle device described herein. The “drug formulation” is a formulation of a drug, which typically includes one or more pharmaceutically acceptable excipient materials known in the art. The term “excipient” refers to any non-active ingredient of the formulation intended to facilitate handling, stability, dispersibility, wettability, release kinetics, and/or injection of the drug. In one embodiment, the excipient may include or consist of water or saline.
In one embodiment, the fluid drug formulation includes microparticles or nanoparticles, either of which includes at least one drug. Desirably, the microparticles or nanoparticles provide for the controlled release of drug into the ocular tissue. As used herein, the term “microparticle” encompasses microspheres, microcapsules, microparticles, and beads, having a number average diameter of 1 to 100 μm, most preferably 1 to 25 μm. The term “nanoparticles” are particles having a number average diameter of 1 to 1000 nm. Microparticles may or may not be spherical in shape. “Microcapsules” are defined as microparticles having an outer shell surrounding a core of another material. The core can be liquid, gel, solid, gas, or a combination thereof. In one case, the microcapsule may be a “microbubble” having an outer shell surrounding a core of gas, wherein the drug is disposed on the surface of the outer shell, in the outer shell itself, or in the core. (Microbubbles may be respond to acoustic vibrations as known in the art for diagnosis or to burst the microbubble to release its payload at/into a select ocular tissue site.) “Microspheres” can be solid spheres, can be porous and include a sponge-like or honeycomb structure formed by pores or voids in a matrix material or shell, or can include multiple discrete voids in a matrix material or shell. The microparticle or nanoparticles may further include a matrix material. The shell or matrix material may be a polymer, amino acid, saccharide, or other material known in the art of microencapsulation.
The drug-containing microparticles or nanoparticles may be suspended in an aqueous or non-aqueous liquid vehicle. The liquid vehicle may be a pharmaceutically acceptable aqueous solution, and optionally may further include a surfactant. The microparticles or nanoparticles of drug themselves may include an excipient material, such as a polymer, a polysaccharide, a surfactant, etc., which are known in the art to control the kinetics of drug release from particles.
In one embodiment, the fluid drug formulation further includes an agent effective to degrade collagen or GAG fibers in the sclera, which may enhance penetration/release of the drug into the ocular tissues. This agent may be, for example, an enzyme, such a hyaluronidase, a collagenase, or a combination thereof. In a variation of this method, the enzyme is administered to the ocular tissue in a separate step from—preceding or following—infusion of the drug. The enzyme and drug are administered at the same site.
In another embodiment, the drug formulation is one which undergoes a phase change upon administration. For instance, a liquid drug formulation may be injected through hollow microneedles into the suprachoroidal space, where it then gels and the drug diffuses out from the gel for controlled release.
The embodiments described herein can be formed or constructed of one or more biocompatible materials. For example, any of the microneedles shown and described herein can be constructed of a substantially rigid material such that the microneedle does not substantially deform when used according to the methods described herein. Examples of suitable biocompatible materials include metals, glasses, ceramics, polymers, and/or nanotubes (e.g., carbon nanotubes). Examples of suitable metals include pharmaceutical grade stainless steel, gold, titanium, nickel, iron, platinum, tin, chromium, copper, and alloys thereof. The polymer may be biodegradable or non-biodegradable. Examples of suitable biodegradable polymers include polylactides, polyglycolides, polylactide-co-glycolides (PLGA), polyanhydrides, polyorthoesters, polyetheresters, polycaprolactones, polyesteramides, poly(butyric acid), poly(valeric acid), polyurethanes and copolymers and blends thereof. Examples of non-biodegradable polymers include nylons, polyesters, polycarbonates, polyacrylates, polymers of ethylene-vinyl acetates and other acyl substituted cellulose acetates, non-degradable polyurethanes, polystyrenes, polyvinyl chloride, polyvinyl fluoride, poly(vinyl imidazole), chlorosulphonate polyolefins, polyethylene oxide, blends and copolymers thereof.
The microneedles described herein can be fabricated by a variety of methods. For example, in some embodiments, the hollow microneedle is fabricated using a laser or similar optical energy source. In one example, a microneedle and/or microcannula may be cut using a laser to represent the desired microneedle length. The laser may also be use to shape single or multiple tip openings. Single or multiple cuts may be performed on a single microcannula to shape the desired microneedle structure. In one example, the microcannula may be made of metal such as stainless steel and cut using a laser with a wavelength in the infrared region of the light spectrum (0.7-300 μm). Further refinement may be performed using metal electropolishing techniques familiar to those in the field. In another embodiment, the microneedle length and optional bevel can be formed by a physical grinding process, which, for example, may include grinding a metal cannula against a moving abrasive surface. The fabrication process may further include precision grinding, micro-bead jet blasting and/or ultrasonic cleaning to form the shape of the desired precise tip of the microneedle.
While various embodiments have been described above, it should be understood that they have been presented by way of example only, and not limitation. Where methods described above indicate certain events occurring in certain order, the ordering of certain events may be modified. Additionally, certain of the events may be performed concurrently in a parallel process when possible, as well as performed sequentially as described above
Where schematics and/or embodiments described above indicate certain components arranged in certain orientations or positions, the arrangement of components may be modified. Similarly, where methods and/or events described above indicate certain events and/or procedures occurring in certain order, the ordering of certain events and/or procedures may be modified. While the embodiments have been particularly shown and described, it will be understood that various changes in form and details may be made.
For example, although the microneedles are shown and described herein as being substantially linear (i.e., having a linear center line) and being substantially rigid, in other embodiments a microneedle, such as, for example, the microneedles 310, 410 and 610 can be curved and/or can define a substantially curved lumen therethrough. In yet other embodiments, any of the microneedles described herein (e.g., the microneedles 310, 410 and 610) can be flexible.
Although various embodiments have been described as having particular features and/or combinations of components, other embodiments are possible having a combination of any features and/or components from any of embodiments as discussed above.
For example, although the microneedles 310, 410, 510 and 610 can have the diameters and wall thickness as specified by the microneedle 710 shown and described above. Moreover, any of the microneedles described herein can have a variable-thickness wall, similar to that shown in the microneedle 910.
