The invention provides methods, compositions, and kits containing a pharmaceutical composition, for treating meibomian gland dysfunction, dry eye disease, and related disorders.
Functioning meibomian glands play a critical role in maintaining optimal ocular surface conditions. One common disorder observed in patients by eye care professionals, including ophthalmologists and optometrists, is meibomian gland dysfunction. Meibomian gland dysfunction typically features meibomian glands that either hyposecrete or are obstructed. Meibomian gland dysfunction has historically been treated on a chronic basis through either mechanical therapy (e.g., eyelid hygiene, eyelid massage, or eyelid compression/expression) alone or in combination with topical or systemic antibiotics or topical immunosuppressants such as steroids or cyclosporine. The need exists for meibomian gland dysfunction therapies that are more effective and/or have reduced adverse side effects.
Dry Eye Disease (DED) is a relatively common condition characterized by inadequate tear film protection of the cornea. DED often causes ocular discomfort, a degradation in visual performance (reading speed, contrast sensitivity), and a loss of productivity. Many millions of people worldwide suffer from DED, with it being more frequently diagnosed in aging patient populations. Currently available options for treating DED are limited and costly.
The present invention addresses the need for improved therapies for meibomian gland dysfunction, dry eye disease, and related disorders and provides other related advantages.
The invention provides methods, compositions, and kits containing a pharmaceutical composition, for treating meibomian gland dysfunction, dry eye disease, and related disorders. The pharmaceutical composition contains (i) an ethylene-propylene-styrene copolymer and (ii) optionally one or more of a butylene-ethylene-styrene copolymer, mineral oil, an antioxidant and one or more pharmaceutically acceptable carriers and/or excipients. Preferably, the pharmaceutical composition contains an ethylene-propylene-styrene copolymer, a butylene-ethylene-styrene copolymer, mineral oil, and an antioxidant. The pharmaceutical composition is preferably in the form of a gel and is topically administered to the eyelid margin of the patient's eye. Without limiting the scope of patients that achieve benefits from the therapy, it has been observed that patients having non-inflammatory meibomian gland dysfunction respond particularly well to treatment using the pharmaceutical composition administered twice per day. Exemplary aspects and embodiments of the invention are described below.
One aspect of the invention provides a method of treating meibomian gland dysfunction. The method consists of topically administering to the eyelid margin of a patient in need thereof a therapeutically effective amount of a pharmaceutical composition to treat the meibomian gland dysfunction, wherein the pharmaceutical composition consists of: (a) an ethylene-propylene-styrene copolymer; (b) optionally a butylene-ethylene-styrene copolymer; (c) optionally mineral oil; (d) optionally an antioxidant; and (e) optionally one or more pharmaceutically acceptable carriers and/or excipients. Additional pharmaceutical compositions for use in the method are described in the detailed description, along with additional features and benefits of the method.
Another aspect of the invention provides a method of treating dry eye disease. The method consists of topically administering to the eyelid margin of a patient in need thereof a therapeutically effective amount of a pharmaceutical composition to treat the dry eye disease, wherein the pharmaceutical composition consists of: (a) an ethylene-propylene-styrene copolymer; (b) optionally a butylene-ethylene-styrene copolymer; (c) optionally mineral oil; (d) optionally an antioxidant; and (e) optionally one or more pharmaceutically acceptable carriers and/or excipients. Additional pharmaceutical compositions for use in the method are described in the detailed description, along with additional features and benefits of the method.
The above methods may be further characterized according to, for example, features of the pharmaceutical composition, patients to receive treatment, the dose of the pharmaceutical composition, the frequency of administration of the pharmaceutical composition, and results produced by the method. In certain embodiments, the patient has evaporative dry eye disease.

The invention provides methods, compositions, and kits containing a pharmaceutical composition, for treating meibomian gland dysfunction, dry eye disease, and related disorders. The pharmaceutical composition contains (i) an ethylene-propylene-styrene copolymer and (ii) optionally one or more of a butylene-ethylene-styrene copolymer, mineral oil, an antioxidant and one or more pharmaceutically acceptable carriers and/or excipients. Preferably, the pharmaceutical composition contains an ethylene-propylene-styrene copolymer, a butylene-ethylene-styrene copolymer, mineral oil, and an antioxidant. The pharmaceutical composition is preferably in the form of a gel and is topically administered to the eyelid margin of the patient's eye. Without limiting the scope of patients that achieve benefits from the therapy, it has been observed that patients having non-inflammatory meibomian gland dysfunction respond particularly well to treatment using the pharmaceutical composition administered twice per day. Various aspects of the invention are set forth below in sections; however, aspects of the invention described in one particular section are not to be limited to any particular section.
To facilitate an understanding of the present invention, a number of terms and phrases are defined below.
The terms “a,” “an” and “the” as used herein mean “one or more” and include the plural unless the context is inappropriate.
As used herein, the term “non-inflammatory meibomian gland dysfunction” refers to meibomian gland dysfunction where there is no substantial amount of inflammation in the patient's meibomian glands. Non-inflammatory meibomian gland dysfunction can be assessed, for example, by measuring the concentration of matrix metalloproteinase-9 (MMP-9) in the patient's tear film. A MMP-9 tear film concentration less than about 35 ng/mL is generally indicative of no substantial amount of inflammation in the patient's meibomian glands. More preferably, a MMP-9 tear film concentration less than about 30, 25, 20, 15, 10, or 5 ng/mL is generally indicative of no substantial amount of inflammation in the patient's meibomian glands. Visual indicators of inflammation of the meibomian glands may also be used to determine if the patient has a substantial amount of inflammation in their meibomian glands.
As used herein, the term “patient” refers to organisms to be treated by the methods of the present invention. Such organisms preferably include, but are not limited to, mammals (e.g., murines, simians, equines, bovines, porcines, canines, felines, and the like), and most preferably includes humans.
As used herein, the term “effective amount” refers to the amount of a compound sufficient to effect beneficial or desired results. Unless specified otherwise, an effective amount can be administered in one or more administrations, applications or dosages and is not intended to be limited to a particular formulation or administration route. As used herein, the term “treating” includes any effect, e.g., lessening, reducing, modulating, ameliorating or eliminating, that results in the improvement of the condition, disease, disorder, and the like, or ameliorating a symptom thereof.
As used herein, the term “pharmaceutically acceptable carrier” refers to any of the standard insert pharmaceutical carriers. Exemplary pharmaceutically acceptable carriers include, for example, water, isotonic saline, phosphate buffered saline solution, cellulose, Ringer's solution, corn starch, potato starch, lactose, glycose, and sucrose.

The pharmaceutical composition desirably displays non-Newtonian physical properties. That is, the pharmaceutical composition is a non-Newtonian fluid. Such non-Newtonian physical properties provide superior residence time on the eyelid margin when the pharmaceutical composition is applied to the eyelid margin. Such non-Newtonian physical properties also minimize exposure of the cornea surface to the pharmaceutical composition when the pharmaceutical composition is applied to the eyelid margin.
A desired non-Newtonian physical property is where the pharmaceutical composition undergoes a reduction in viscosity due to mechanical forces imposed on the pharmaceutical composition due to the patient blinking their eye.
Viscosity of the pharmaceutical composition can be measured a different shear rates. For example, in certain embodiments, at a shear rate of 6 (1/s), the pharmaceutical composition has a viscosity in the range of from about 1,000 cP to about 45,000 cP, from about 3,000 cP to about 30,000 cP, from about 3,000 cP to about 25,000 cP, from about 3,000 cP to about 20,000 cP, from about 3,000 cP to about 15,000 cP, from about 5,000 cP to about 30,000 cP, from about 5,000 cP to about 25,000 cP, from about 5,000 cP to about 20,000 cP, from about 5,000 cP to about 15,000 cP, from about 6,000 cP to about 20,000 cP.

In certain embodiments, the pharmaceutical composition is topically administered to the eyelid margin of the patient to form a strip having a width of about one-quarter inches. In certain embodiments, the pharmaceutical composition is topically administered across the full margin of the eyelid.
When administering the pharmaceutical composition to the eyelid margin, one embodiment is for the patient to pull down the lower eyelid and look up, then use their finger to apply the pharmaceutical composition (e.g., a pea sized amount of pharmaceutical composition) to the inside of the lower eyelid, between the lower eyelid and the eye. The patient may optionally apply the pharmaceutical composition as a thin ribbon on the lower eyelid close to their nose (inner canthus) and direct outward without touching the eyelash or the eye. The ribbon of the pharmaceutical composition is desirably deposited on the inside lining of the lower eyelid.
Application of the pharmaceutical composition to the eyelid margin desirably brings the pharmaceutical composition into contact with one or more of the tarsal conjunctiva, conjunctival fornix, bulbar conjunctiva, or conjunctival sac. This disclosure provides methods where, in lieu of applying the pharmaceutical composition as a strip across the eyelid margin, the pharmaceutical composition is administered directly to one or more of the tarsal conjunctiva, conjunctival fornix, bulbar conjunctiva, or conjunctival sac.

A pharmaceutical composition for use in topical application to patients was prepared according to the procedures described below.
General Procedure: Mineral oil was mixed with the polymeric hydrocarbon gelling agent sold under the tradename VERSAGEL® M-750, which is a mixture of ethylene-propylene-styrene copolymer, butylene-ethylene-styrene copolymer, butylated-hydroxytoluene, and mineral oil. The polymeric hydrocarbon gelling agent sold under the tradename VERSAGEL® M-750 contained (i) ethylene-propylene-styrene copolymer (having a weight-average molecular weight of about 200,000 g/mol) in an amount within the range of 2.5% to 10% (w/w), (ii) butylene-ethylene-styrene copolymer (having a weight-average molecular weight of about 100,000 g/mol) in an amount within the range of 0.1% to 2.5% (w/w), (iii) butylated-hydroxytoluene in an amount <0.5% (w/w), and (iv) mineral oil (e.g., having a weight-average molecular weight in the range of 230-700 g/mol). A description of the pharmaceutical composition prepared is described in Table 1 below.
The pharmaceutical composition was subjected to sterilization, and then packaged in lacquer-lined aluminum tubes with a nasal tip and a low density polyethylene cap closure.
In a clinical study, human subjects suffering from meibomian gland dysfunction were treated by topical administration of a Test Pharmaceutical Composition to the eyelid margin of the subject. Subjects were evaluated for improvement. Experimental procedures for the clinical study are provided below, along with results from the clinical study.
Human subjects suffering from inflamed meibomian gland dysfunction that met enrollment criteria were enrolled in the study. Test Pharmaceutical Composition (also referred to as Investigational Product (IP)) was administered to both eyes twice daily (i.e., BID) during the study. Each dose of IP was delivered using a fingertip, as an instillation of approximately ¼ inch strip (equivalent to approximately 50 μL drop) in each eye. IP was instilled to full eyelid margin. Subjects were instructed to wash hands thoroughly prior to administration of IP. Following administration of the IP, subjects were allowed to blot or clean the lower eyelid skin, if necessary.
At Visit 1 (Screening) informed consent was obtained from subjects and eligibility was determined. After the screening assessment, eligible subjects entered into a 2-week run-in period, during which IP BID was instilled in each eye.
At Visit 2 (Baseline) eligibility was reconfirmed and subjects began daily BID administration of IP for twelve weeks. At Visit 3 (Week 2), Visit 4 (Week 4), Visit 5 (Week 8), and Visit 6 (Week 12) subjects attend clinic visits where efficacy and safety evaluations were performed. Subjects who discontinued before Visit 6 underwent Visit 6 evaluations (at the Early Termination visit).
At Visit 7 (Week 16) Post-Treatment Follow-up Visit, efficacy and safety evaluations were performed.
IP was supplied as a sterile ointment packaged in a 5 gm lacquer-lined aluminum tube with a nasal tip and a low density polyethylene cap closure. Composition of the IP is set forth in Table 2.
The polymeric hydrocarbon gelling agent commercially available under the tradename VERSAGEL® M-750 is a mixture of ethylene-propylene-styrene copolymer, butylene-ethylene-styrene copolymer, butylated-hydroxytoluene, and mineral oil, wherein the ethylene-propylene-styrene copolymer (having a weight-average molecular weight of about 200,000 g/mol) was present in an amount within the range of 2.5% to 10% (w/w), the butylene-ethylene-styrene copolymer (having a weight-average molecular weight of about 100,000 g/mol) was present in an amount within the range of 0.1% to 2.5% (w/w), the butylated-hydroxytoluene was present in an amount <0.5% (w/w), and the remainder was mineral oil (e.g., having a weight-average molecular weight in the range of 230-700 g/mol). The IP was prepared based on procedures described in Example 1, whereby the polymeric hydrocarbon gelling agent commercially available under the tradename VERSAGEL® M-750 was mixed with mineral oil (USP Mineral Oil, having a specific gravity from 0.845 to 0.905 and a kinematic viscosity of not less than 34.5 centistokes at 40° C.) and the resulting mixture subjected to sterilization to produce IP having the composition set forth in Table 2.
At Visit 1, (Day −14/Screening), subjects received their first dose of IP which was self-administered in the clinic under the supervision of the Dedicated Dosing Coordinator. IP was instilled to the full eyelid margin. Subjects were instructed to wash hands thoroughly prior to administration of IP. (Following administration of the IP, subjects were allowed to blot or clean the lower eyelid skin, if necessary.)
They then received one tube of IP from a general supply to take home for self-administration. The tube of IP was returned to the site at Visit 2 (Day 1).
At Visit 2, subjects were assigned a kit containing six tubes of IP. The first dose of IP was self-administered in the clinic by the subject under the supervision of the Dedicated Dosing Coordinator. Subjects then received one tube of IP from their assigned kit to take home for self-administration. Subjects were instructed to apply IP to the full eyelid margin and to wash hands thoroughly prior to administration of IP as was the same at Visit 1.
Subjects were instructed to return the used tube of IP at Visit 3 and at Visit 3 will receive one new tube of IP which is returned at Visit 4. At Visits 4 and 5, subjects received two new tubes of IP at each visit which were returned at Visits 5 and 6, respectively.
At Visit 1, subjects self-administer the first dose of IP in the clinic under the supervision of the Dedicated Dosing Coordinator. Subjects then self-administer additional doses of investigational product during the remainder of the run-in period. At Visit 2, subjects self-administer their first dose of IP under the supervision of the Dedicated Dosing Coordinator. Subjects then self-administer additional doses of IP during the remainder of the study. Visits were to be scheduled in the morning to allow subjects to receive the two daily doses 8 to 12 hours apart, with the AM dose occurring in the clinic for Visit 2/Day 1±2 days.
Subjects were asked to instill the first daily dose upon awakening and then the second daily dose approximately 8 to 12 hours later. The two daily doses are described as “Morning (AM) Dose” and “Evening (PM) Dose.”
Following Visit 2, clinic visits were scheduled prior to the subject administration of their morning dose if possible. If the subject did take a dose, the visit was to be scheduled at least 2 hours following the morning dose to prevent the subject from being evaluated with residual investigational product on the eyelids.
The following primary efficacy endpoints were used to evaluate effect of the IP:
Secondary endpoints of the study include:
Safety endpoints of the study include:
At Visit 1, individuals of any gender or any race were eligible for study participation if they:
In order for subjects to be eligible at Visit 1 they may not:
The study eye was the eye with the eyelid at Visit 2, having the worst (higher) score defined as the sum of the following two severity scores for the clinical signs of Meibomian Gland Disease (Note, the study eye and eyelid must have met qualifying eligibility criteria at Visit 1 and Visit 2):
If both eyes, and eyelids, had the same score, then the right eye and upper eyelid was selected.
At the Visit 2, an eligible subject must continue to meet all clinical inclusion/exclusion criteria as defined above. Subjects must meet all criteria from Visit 1 and inflamed MGD criteria in the same qualifying eye and/or qualifying eyelid as in Visit 1. Further, subjects must be 80% compliant with respect to dosing of run-in IP and diary completion.
The absence or presence of evaporative DED in the study eye was noted. A clinical diagnosis of evaporative DED in the study eye, was defined as meeting the following criteria at Visit 2 (Baseline):
Visit assessments were performed in the order suggested in both eyes.
The following was performed/assessed in the order suggested below and in both eyes:
Visit 2 occurs 14 (±2) days after Visit 1 (Screening). The following was performed/assessed in both eyes:
This visit occurs on Day 15 as calculated from Visit 2: Day 1, and the following was performed in both eyes:
This visit occurs on Day 29 as calculated from Visit 2: Day 1, and the following was performed in both eyes:
This visit occurs on Day 57 as calculated from Visit 2: Day 1, and the following was performed in both eyes:
This visit occurs on Day 85 as calculated from Visit 2: Day 1, and the following was performed in both eyes:
This visit occurs on Day 113 as calculated from Visit 6 (End of Treatment), and the following was performed in both eyes:
The subject may be discharged from the study at this visit.
Any visits or procedures performed beyond those specified within the protocol were to be documented.
In the event of termination prior to Visit 6, every attempt was made to ensure that all the following Visit 6 assessments were performed in both eyes at the Early Termination Visit prior to discharge from the study:
Include subject withdrawal criteria (i.e., terminating investigational product treatment/trial treatment).
I. Subject Withdrawal and/or Discontinuation
Any subject who wished to discontinue IP use or withdraw from participation in the study for any reason was entitled to do so without obligation. The Investigator could also discontinue any subject from investigational product use or from study participation, if deemed necessary.
Efficacy assessments included the following:
The SANDE questionnaire was assessed at each visit. The subject was asked the following questions regarding the frequency and severity of their dry eye symptoms:
Subjects were asked the following questions regarding their current symptoms (unrelated to study drug instillation) at each visit. The subject is asked to subjectively rate each ocular symptom (OU) by placing a vertical mark on the horizontal line to indicate the level of discomfort. 0 corresponds to “No Symptoms” and 100 corresponds to “Severe Symptoms”
Subjects were asked to record each day the following information related to administration of investigational product:
Symptom Flare Question: Each evening, the subject was asked to respond to the following question:
Tear osmolarity was collected at each visit at a subset of clinical sites. Tear osmolarity is an objective measurement of the salinity and its concentration in an individual's tears. The mean tear osmolarity score is obtained at each visit.
FCS was assessed at each visit. The five areas of the cornea were scored by the investigator according to the scoring system shown in
The Schirmer test was conducted on unanesthetized eyes at Visits 1, 2, 6, and 7. A 35 mm×5 mm filter paper strip was used to measure the amount of tears that are produced over 5 minutes. The strip was placed in the lower eyelid margin without the use of a preplaced ophthalmic anesthetic drop. After 5 minutes, the strip was removed and the amount of wetting is measured in millimeters.
The MMP-9 point of care assessment was conducted at Visit 1 and Visit 6. The Quidel InflammaDry test system was used to assess the tear film for the presence of MMP-9. The sample is obtained, and the test performed according to package instructions.
TFBUT was measured at each visit. To measure TFBUT, fluorescein was instilled into the subject's tear film, the subject was allowed to blink once or twice to disperse the fluorescein, and the subject was then asked not to blink while the tear film is observed under a broad beam of cobalt blue illumination using a slit-lamp. The TFBUT is recorded as the number of seconds that elapse between the last blink and the appearance of the first dry spot in the tear film. A TFBUT under 10 seconds is considered abnormal.
9. Investigator-Rated Assessment of Objective Signs Including Change from Baseline for Five Individual Severity Scores
The investigator rated the bilateral severity of the subject's MGD signs at each visit according to the following classification:
Safety parameters included:
See Section O. Adverse Event Definitions
BCVA was conducted at each visit. Visual acuity testing should precede any examination requiring contact with the eye or instillation of study dyes, as is detailed in the order of assessments for each Visit in Section 5.1. Logarithm of the Minimal Angle of Resolution (Log MAR) visual acuity must be assessed using an ETDRS or modified ETDRS chart. Visual acuity testing is performed with best correction using subject's own corrective lenses (spectacles only) or pinhole refraction.
An ETDRS or modified ETDRS chart may be used. If a Lighthouse chart is used (24.5″ by 25″; either reflectance or retro-illuminated), the subject must view the chart from a distance of exactly 4 meters (13.1 feet). If smaller reproductions (18″ by 18″, e.g., Prevent Blindness) are used, the subject viewing distance is exactly 10 feet. Reflectance wall charts are frontally illuminated (60 watt bulb or a well-lit room).
The subject is positioned according to the elevation of the chart (either seated or standing) so that the chart is at a comfortable viewing angle. The right eye is tested first. The subject should attempt to read each letter, line-by-line, left to right, beginning with line 1 at the top of the chart. The subject is told that the chart has letters only, no numbers. If the subject reads a number, he or she is reminded that the chart contains no numbers, and the examiner should then request a letter instead of the number. The subject is asked to read slowly, about 1 letter per second, to achieve the best identification of each letter. He/she is not to proceed to the next letter until he/she has given a definite response. If the subject changes a response before he has read aloud the next letter, then the change must be accepted.
Maximum effort is made to identify each letter on the chart; the subject is encouraged to guess. When it becomes evident that no further meaningful readings can be made, the examiner should stop the test. The number of letters missed or read incorrectly is noted.
In order to provide standardized and well-controlled assessments of visual acuity during the study, the same lighting conditions must be used consistently throughout the study.
The biomicroscopy exam was performed at each visit. It was performed with the slit lamp using a beam width and intensity that provide optimal evaluation of the anterior segment. This procedure is performed in the same manner for all subjects observed at the Investigator's site.
IOP measurements were performed utilizing Goldmann applanation tonometry according to the Investigator's standard procedure. All pressures are recorded in mmHg.
Dilated ophthalmoscopy includes assessment of the optic nerve head for pallor and cupping (cup to disc ratio), and was performed at Visit 1 and Visit 6. After the ophthalmoscopy procedure, the Investigator determined if findings are within normal limits or are abnormal. For abnormal findings at Visit 1, the Investigator determined whether or not the abnormality would exclude subject from study participation.
