Patent Application

The present invention relates to the treatment or prevention of a disease or disorder using a drug in the form of micro- or nanoparticles in suspension, in combination with a hyaluronidase.
It is often desirable to keep the blood plasma concentration of a drug above a minimum level in order for the drug to provide an effective treatment or prevention of a disease or disorder. At blood plasma concentrations lower than the minimum blood plasma level, the drug may no longer be effective.
The time interval between administrations of a drug may be selected to alter the blood plasma levels of the drug and its metabolites. The time interval may be short (e.g. one day) where the drug reaches the blood plasma quickly and does not remain in the blood plasma for a long time period, or the time interval may be long (e.g. six months) where slower release into the blood plasma or slower clearance from the blood plasma means that the blood plasma levels of the drug are sufficiently high for a long time period.
Because of their pharmacokinetic properties and the need to keep blood plasma levels above a minimum level, many drugs require frequent administration, often at high doses. The number and/or volume of the dosage forms containing the drug that needs to be administered is commonly referred to as the “pill burden”. While a high pill burden may enable the blood plasma level to be kept suitably high, it is undesirable for many reasons.
For example, a high pill burden requires a high frequency of intake and often large volumes of the dosage form need to be stored and transported. For drugs administered by subcutaneous or intramuscular injection, patient tolerability is an additional concern, certainly when large volumes are injected. For example, administration by subcutaneous or intramuscular injection can result in irritation, inflammation, swelling, acute pain and/or redness and bruising during and after injection at the injection site (injection site reactions). Subcutaneous and intramuscular injections may also be associated with the manifestation of a bump at the surface of the skin at the injection site. Such effects are generally exaggerated by a high injection volume. Such a bump may reveal that the subject concerned received a high volume injection and may hence reveal that the subject is receiving an intervention for a disease or disorder.
Therefore, there is a need to provide drug formulations that allow the blood plasma level of the administered drug to remain above the minimum level for treatment or prevention, thus allowing intermittent administration at longer time periods, and which are well tolerated, which in turn improves patient compliance. There is also a need for this method to be non-visible to the outside world. Areas of interest include but are not limited to the treatment of human immunodeficiency virus (HIV) infection, and the treatment of cancer.
In a first aspect there is provided a method for the treatment or prevention of a disease or disorder in a subject in need thereof, the method comprising administering to the subject a drug effective in the treatment or prevention of the disease or disorder in the form of micro- or nanoparticles in suspension by intramuscular injection or subcutaneous injection, wherein the drug is administered in combination with a hyaluronidase that is administered by intramuscular injection or subcutaneous injection, and wherein the drug and the hyaluronidase are administered intermittently at a time interval of about three months to about two years.
In a second aspect there is provided a drug and a hyaluronidase for use in therapy, wherein the drug is in the form of micro- or nanoparticles in suspension, wherein the drug and hyaluronidase are administered by intramuscular injection or subcutaneous injection, and wherein the drug and hyaluronidase are administered intermittently at a time interval of about three months to about two years.
In a third aspect there is provided products containing a drug and a hyaluronidase as a combined preparation for simultaneous or sequential use in therapy by intramuscular injection or subcutaneous injection, wherein the drug is in the form of micro- or nanoparticles in suspension, and wherein the drug and the hyaluronidase are administered intermittently at a time interval of about three months to about two years.
In a fourth aspect there is provided a kit of parts comprising a drug and a hyaluronidase for simultaneous or sequential use in therapy by intramuscular injection or subcutaneous injection, wherein the drug is in the form of micro- or nanoparticles in suspension, and wherein the drug and the hyaluronidase are administered intermittently at a time interval of about three months to about two years.
In a fifth aspect there is provided a drug in the form of micro- or nanoparticles in suspension for use in therapy by intramuscular or subcutaneous injection, wherein the drug is administered in combination with a hyaluronidase that is administered by intramuscular injection or subcutaneous injection, and wherein the drug and the hyaluronidase are administered intermittently at a time interval of about three months to about two years.
In a sixth aspect there is provided use of a drug for the manufacture of a medicament for use in the treatment of a disease or disorder in a subject, wherein the drug is in the form of micro- or nanoparticles in suspension and is administered in combination with a hyaluronidase, wherein the drug and the hyaluronidase are administered to the subject by subcutaneous or intramuscular injection, and wherein the drug and the hyaluronidase are administered intermittently at a time interval of about three months to about two years.
Administration of the drug with a hyaluronidase improves patient tolerability for subcutaneous or intramuscular injection administration routes compared with subcutaneous or intramuscular injection administration of the drug alone, in particular when large volumes are injected. The hyaluronidase may facilitate a more rapid administration of the drug as it may lower the resistance of the tissue against which the drug suspension is delivered. The hyaluronidase may reduce leakage of the drug from the site of injection by decreasing the tissue backpressure. The hyaluronidase may also allow for delivery of larger volumes in patients with less subcutaneous tissue (or lower body mass index). The hyaluronidase may allow the use of a shorter needle.
In addition, it has surprisingly been found that an extended, sustained or prolonged release of a drug into the blood plasma achieved by intramuscular injection or subcutaneous injection of a suspension of micro- or nanoparticles can be maintained when the drug is administered by intramuscular injection or subcutaneous injection with a hyaluronidase as defined herein. As discussed in more detail below in the section titled “Hyaluronidase”, hyaluronidases are used for increasing the dispersion and absorption of injected active pharmaceutical ingredients. In view of this, it is surprising that the inventors have demonstrated that administration of a hyaluronidase with a drug maintains an extended, sustained or prolonged release of drug into the bloodstream.
The invention will be described, by way of example only, with reference to the accompanying figures.
These figures are explained further in the “Examples” section.
This application has been drafted in sections to aid readability. However, this does not mean that each section is to be read in isolation. To the contrary, unless otherwise specified, each section is to be read with cross-referencing to the other sections, i.e. taking the entire application as a whole. No artificial separation of embodiments is intended, unless explicitly stated.
Thus, all of the embodiments described herein relating to the first aspect of the invention apply equally to, i.e. are also disclosed in relation to/combination with, the other aspects described herein.
The Drug(s) Used in the Invention
The drug used in the invention as described herein is in suspension. Preferably, the drug used in the invention is in the form of micro- or nanoparticles in suspension, i.e. a suspension of the drug, wherein the drug is in the form of microparticles or nanoparticles, in particular microparticles or nanoparticles of the drug suspended in a pharmaceutically acceptable carrier, such as for example a pharmaceutically acceptable aqueous carrier. For the avoidance of doubt, the drug described herein is not the hyaluronidase described herein.
The skilled person would understand that the size of the micro- or nanoparticles should be below a maximum size above which administration by subcutaneous or intramuscular injection becomes impaired or is even no longer possible. The maximum size depends for example on the limitations imposed by the needle diameter or by adverse reactions of the body to large particles, or both.
In a preferred embodiment, the drug is in the form of nanoparticles.
In an embodiment, the micro- or nanoparticles described herein have an average effective particle size of less than about 20 μm. In an embodiment, the micro- or nanoparticles have an average effective particle size of less than about 10 μm. In an embodiment, the micro- or nanoparticles have an average effective particle size of less than about 5 μm. In an embodiment, the micro- or nanoparticles have an average effective particle size of less than about 1 μm. In an embodiment, the micro- or nanoparticles have an average effective particle size of less than about 500 nm.
In another embodiment, the micro- or nanoparticles described herein have an average effective particle size of from about 25 nm to about 20 μm. In another embodiment, the micro- or nanoparticles have an average effective particle size of from about 25 nm to about 10 μm (e.g. about 200 nm to about 10 μm). In another embodiment, the micro- or nanoparticles have an average effective particle size of from about 25 nm to about 5 μm (e.g. about 200 nm to about 5 μm). In another embodiment, the micro- or nanoparticles have an average effective particle size of from about 25 nm to about 1 μm. In another embodiment, the micro- or nanoparticles have an average effective particle size of from about 25 nm to about 500 nm, e.g. about 100 nm to about 300 nm.
When the drug is rilpivirine or a pharmaceutically acceptable salt thereof the micro- or nanoparticles preferably have an average effective particle size of from about 100 nm to about 300 nm, for example about 150 nm to about 250 nm or about 180 nm to about 220 nm, e.g. about 200 nm.
The term “average effective particle size” as used herein refers to the volume-based median particle diameter (Dv50), i.e. the diameter below which 50% by volume of the particle population is found.
The average effective particle sizes, i.e. the volume-based median particle diameter, as used herein are determined by routine laser diffraction techniques, e.g. in accordance with ISO 13320:2009.
Laser diffraction relies on the principle that a particle will scatter light at an angle that varies depending on the size the particle and a collection of particles will produce a pattern of scattered light defined by intensity and angle that can be correlated to a particle size distribution. A number of laser diffraction instruments are commercially available for the rapid and reliable determination of particle size distributions. For example, particle size distribution may be measured by the conventional Malvern Mastersizer™ 3000 particle size analyzer from Malvern Instruments. The Malvern Mastersizer™ 3000 particle size analyzer operates by projecting a helium-neon gas laser beam through a transparent cell containing the particles of interest suspended in an aqueous solution. Light rays which strike the particles are scattered through angles which are inversely proportional to the particle size and a photodetector array measures the intensity of light at several predetermined angles and the measured intensities at different angles are processed by a computer using standard theoretical principles to determine the particle size distribution. Laser diffraction values may be obtained using a wet dispersion of the particles in distilled water.
Other methods that are commonly used in the art to measure volume-based median particle diameters include disc centrifugation, scanning electron microscopy (SEM), sedimentation field flow fractionation and photon correlation spectroscopy.
In an embodiment, the method or use or combination or products or kit of parts as described herein are used in combination with one or more other drugs.
In an embodiment, said one or more other drugs is administered at the same intermittent time interval as the drug and hyaluronidase as described herein, e.g. the drug, hyaluronidase and the other drug are administered intermittently at a time interval of about three months, or of about four months, or of about five months or of about six months or of about seven months or of about eight months or of about ten months or of about eleven months or of about one year or of about one year to about 2 years. In an embodiment the drug, the hyaluronidase and the one or more other drugs are administered simultaneously or sequentially by intramuscular or subcutaneous injection, in particular subcutaneous injection. In an embodiment the drug, the hyaluronidase and the one or more other drugs, are administered simultaneously, in particular by subcutaneous injection. In an embodiment the drug, the hyaluronidase and the one or more other drugs, are administered sequentially, in particular by subcutaneous injection. In an embodiment, the hyaluronidase is administered first followed by sequential administration of the drugs.

The term “drug” includes any substance that is biologically active, for example a compound in free base form or a pharmaceutically acceptable salt thereof, and also encompasses tautomers, solvates (e.g. hydrates) and crystalline or amorphous solid forms thereof, and the like. The term “drug” also includes prodrugs. In an embodiment, the drug is not a biologic. By “biologic” it is meant a virus, therapeutic serum, toxin, antitoxin, vaccine, blood, blood component or derivative, allergenic product, protein, or analogous product, or arsphenamine or derivative of arsphenamine (or any other trivalent organic arsenic compound), applicable to the prevention, treatment, or cure of a disease or condition, for example, of human beings. In an embodiment, the drug is not an antibody. In another embodiment, the drug has a molecular weight (MW) of less than 1000 Da. In another embodiment, the drug has a molecular weight (MW) of less than 1000 Da and is not a biologic.
In an embodiment, the drug is selected from drugs for treatment of chronic and long-term diseases and disorders, for example for treatment of chronic viral infection (such as chronic infection with Varicella-zoster virus, measles virus, HIV, hepatitis B virus, hepatitis C virus, hepatitis D virus or human cytomegalovirus), cancer, psychiatric diseases and disorders, mood disorders (such as bipolar, cyclothymic or depression), diabetes, hypertension, abnormal cholesterol and triglyceride levels, inflammatory disorders (such as allergy, asthma, autoimmune diseases, coeliac disease, hepatitis, inflammatory bowel disease, Crohn disease, gout, myositis, scleroderma, rheumatoid arthritis, lupus vasculitis, ankylosing spondylitis or chronic obstructive pulmonary disease), cystic fibrosis, multiple sclerosis, autoimmune disorders, neurodegenerative disorders (such as Parkinson Disease or Alzheimer disease), chronic pain, inherited metabolic disorders or epilepsy. In a preferred embodiment, the drug is selected from the list consisting of rilpivirine (TMC278), cabotegravir, apalutamide, enzalutamide, and darolutamide, or pharmaceutically acceptable salts thereof.
In an embodiment, the drug is rilpivirine or a pharmaceutically acceptable salt thereof, in particular rilpivirine.
Rilpivirine (4-[[4-[[4-[(1E)-2-cyanoethenyl]-2,6-dimethylphenyl]amino]-2-pyrimidinyl]amino]benzonitrile; TMC278) has the following structural formula:
By “rilpivirine” it is meant rilpivirine having the structural formula shown above, i.e. the free base form.
Pharmaceutically acceptable salts of rilpivirine means those where the counterion is pharmaceutically acceptable. The pharmaceutically acceptable salts are meant to comprise the therapeutically active non-toxic acid addition salt forms which rilpivirine is able to form. These salt forms can conveniently be obtained by treating rilpivirine with such appropriate acids as inorganic acids, for example, hydrohalic acids, e.g. hydrochloric, hydrobromic and the like; sulfuric acid; nitric acid; phosphoric acid and the like; or organic acids, for example, acetic, propanoic, hydroxyacetic, 2-hydroxypropanoic, 2-oxopropanoic, oxalic, malonic, succinic, maleic, fumaric, malic, tartaric, 2-hydroxy-1,2,3-propanetricarboxylic, methanesulfonic, ethanesulfonic, benzenesulfonic, 4-methylbenzene sulfonic, cyclohexanesulfamic, 2-hydroxybenzoic, 4-amino-2-hydroxybenzoic and the like acids.
In an embodiment, the drug described herein is a next-generation anti-androgen. In an embodiment, the drug is apalutamide.
As used herein, the term “next-generation anti-androgen” refers to an agent that exhibits full antagonist activity against a wild-type androgen receptors (AR) polypeptide. Next-generation anti-androgens differ from first-generation anti-androgens in that second-generation anti-androgens act as full antagonists in cells expressing elevated levels of AR, such as for example, in castration resistant prostate cancers (CRPC).
Exemplary next-generation anti-androgens described herein include apalutamide, enzalutamide (CAS No: 915087-33-1), RD162 (CAS No. 915087-27-3) and darolutamide.
In some embodiments, the next-generation anti-androgen described herein binds to an AR polypeptide at or near the ligand binding site of the AR polypeptide.
In some embodiments, an anti-androgen contemplated in the aspects of the invention described herein inhibits AR nuclear translocation, such as darolutamide, DNA binding to androgen response elements, and coactivator recruitment. In some embodiments, an anti-androgen contemplated in the aspects of the invention described herein exhibits no agonist activity in AR-overexpressing prostate cancer cells.
Apalutamide is a next-generation anti-androgen that binds directly to the ligand-binding domain of AR, impairing nuclear translocation, AR binding to DNA and AR target gene modulation, thereby inhibiting tumor growth and promoting apoptosis. Apalutamide binds AR with greater affinity than bicalutamide and induces partial or complete tumor regression in non-castrate hormone-sensitive and bicalutamide-resistant human prostate cancer xenograft models (Clegg et al. Cancer Res. Mar. 15, 2012 72; 1494). Apalutamide lacks the partial agonist activity seen with bicalutamide in the context of AR overexpression.
Darolutamide, BAY1841788 or ODM-201, is an AR antagonist that includes two diastereomers—ORM-16497 and ORM-16555. It has activity against known AR mutants that confer resistance to other second-generation anti-androgens. Darolutamide binds to the AR with high affinity and impairs subsequent androgen-induced nuclear translocation of AR and transcription of AR gene target (Matsubara, N., Mukai, H., Hosono, A. et al. Cancer Chemother Pharmacol (2017) 80: 1063).
In an embodiment, the micro- or nanoparticles have one or more surface modifiers adsorbed to their surface.
The surface modifier may be selected from known organic and inorganic pharmaceutical excipients, including various polymers, low molecular weight oligomers, natural products and surfactants. Particular surface modifiers that may be used in the invention include nonionic and anionic surfactants. Representative examples of surface modifiers include gelatin, casein, lecithin, salts of negatively charged phospholipids or the acid form thereof (such as phosphatidyl glycerol, phosphatidyl inosite, phosphatidyl serine, phosphatic acid, and their salts such as alkali metal salts, e.g. their sodium salts, for example egg phosphatidyl glycerol sodium, such as the product available under the tradename Lipoid™ EPG), gum acacia, stearic acid, benzalkonium chloride, polyoxyethylene alkyl ethers, e.g., macrogol ethers such as cetomacrogol 1000, polyoxyethylene castor oil derivatives; polyoxyethylene stearates, colloidal silicon dioxide, sodium dodecylsulfate, carboxymethylcellulose sodium, bile salts such as sodium taurocholate, sodium desoxytaurocholate, sodium desoxycholate; methylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, magnesium aluminate silicate, polyvinyl alcohol (PVA), poloxamers, such as Pluronic™ F68, F108 and F127 which are block copolymers of ethylene oxide and propylene oxide; tyloxapol; Vitamin E-TGPS (α-tocopheryl polyethylene glycol succinate, in particular α-tocopheryl polyethylene glycol 1000 succinate); poloxamines, such as Tetronic™ 908 (T908) which is a tetrafunctional block copolymer derived from sequential addition of ethylene oxide and propylene oxide to ethylenediamine; dextran; lecithin; dioctyl ester of sodium sulfosuccinic acid such as the products sold under the tradename Aerosol OT™ (AOT); sodium lauryl sulfate (Duponol™ P); alkyl aryl polyether sulfonate available under the tradename Triton™ X-200; polyoxyethylene sorbitan fatty acid esters (Tweens™ 20, 40, 60 and 80); sorbitan esters of fatty acids (Span™ 20, 40, 60 and 80 or Arlacel™ 20, 40, 60 and 80); polyethylene glycols (such as those sold under the tradename Carbowax™ 3550 and 934); sucrose stearate and sucrose distearate mixtures such as the product available under the tradename Crodesta™ F110 or Crodesta™ SL-40; hexyldecyl trimethyl ammonium chloride (CTAC); polyvinylpyrrolidone (PVP). If desired, two or more surface modifiers can be used in combination.

In an embodiment, the drug (which is in the form of micro- or nanoparticles in suspension) is provided in a separate pharmaceutical composition from the hyaluronidase. As discussed further herein (e.g. in the section titled “Use of the drug and hyaluronidase in the invention”), the separate pharmaceutical composition may be administered sequentially with a pharmaceutical composition comprising the hyaluronidase of the invention, or the separate pharmaceutical composition may be admixed with a pharmaceutical composition comprising the hyaluronidase of the invention prior to administration of the resulting admixed pharmaceutical composition.

In another embodiment, the dose to be administered may be calculated on a basis of about 1 g to about 5 g/month Doses for other dosing regimens can readily be calculated by multiplying the monthly dose with the number of months between each administration. For example, in case of a dose of 1 g/month, and in case of a time interval of 6 months between each administration, the dose to be administered in each administration is 6 g.
In an embodiment, the drug is rilpivirine or a pharmaceutically acceptable salt thereof and for the treatment of a disease or disorder, e.g. HIV infection, the dose to be administered may be calculated on a basis of about 300 mg to about 1200 mg/month, or about 450 mg to about 1200 mg/month, or about 450 mg to about 900 mg/month, or about 600 mg to about 900 mg/month, or about 450 mg to about 750 mg/month, or 450 mg/month, or 600 mg/month, or 750 mg/month, or 900 mg/month. Doses for other dosing regimens can readily be calculated by multiplying the monthly dose with the number of months between each administration. For example, in case of a dose of 450 mg/month, and in case of a time interval of 6 months between each administration, the dose to be administered in each administration is 2700 mg. The indicated “mg” corresponds to mg of rilpivirine (i.e. rilpivirine in its free base form). Thus, by way of example, 1 mg of rilpivirine (i.e. rilpivirine in its free base form) corresponds to 1.1 mg of rilpivirine hydrochloride.
In an embodiment, the drug is rilpivirine or a pharmaceutically acceptable salt thereof and for the treatment of a disease or disorder, e.g. HIV infection, the dose to be administered may be calculated on a basis of about 300 mg to about 1200 mg/4 weeks (28 days), or about 450 mg to about 1200 mg/4 weeks (28 days), or about 450 mg to about 900 mg/4 weeks (28 days), or about 600 mg to about 900 mg/4 weeks (28 days), or about 450 mg to about 750 mg/4 weeks (28 days) or 450 mg/4 weeks (28 days), or 600 mg/4 weeks (28 days), or 750 mg/4 weeks (28 days) or 900 mg/4 weeks (28 days). Doses for other dosing regimens can readily be calculated by multiplying the week or day dose with the number of weeks between each administration. For example, in case of a dose of 450 mg/4 weeks (28 days), and in case of a time interval of 24 weeks between each administration, the dose to be administered in each administration is 2700 mg. Or for example, in case of a dose of 750 mg/4 weeks (28 days), and in case of a time interval of 24 weeks between each administration, the dose to be administered in each administration is 4500 mg. The indicated “mg” corresponds to mg of rilpivirine (i.e. rilpivirine in its free base form). Thus, by way of example, 1 mg of rilpivirine (i.e. rilpivirine in its free base form) corresponds to 1.1 mg of rilpivirine hydrochloride.
In an embodiment, for the treatment of HIV infection, each administration of rilpivirine or a pharmaceutically acceptable salt thereof may comprise from about 900 mg to about 28800 mg (e.g. from about 900 mg to about 14400 mg, or from about 900 mg to about 7200 mg, or from about 900 mg to about 3600 mg), preferably from about 1200 mg to about 14400 mg, preferably from about 1350 mg to about 13200 mg, preferably from about 1500 mg to about 12000 mg, (e.g. from about 3000 mg to about 12000 mg), preferably from about 1800 mg to about 10800 mg (e.g. from about 2700 mg to about 10800 mg, or from about 1800 mg to about 3600 mg), most preferably from about 1800 mg to about 7200 mg or from about 2700 mg to about 4500 mg of the rilpivirine or pharmaceutically acceptable salt thereof.

Hyaluronidase
Hyaluronidase is an enzyme that degrades hyaluronic acid (HA) and lowers the viscosity of hyaluronan in the extracellular matrix. Because of this property, it can be used to increase dispersion and absorption of injected active pharmaceutical ingredients. Enzymatic activity of hyaluronidase, including rHuPH20, can be defined by units per mL (U/mL) or by total enzyme activity in a particular formulation (U).
It is generally known that the delivery of hyaluronidases (E.C. 3.2.1.35/36) into the tissue improves the penetration of drugs. Administration of hyaluronidase thus represents a method of increasing the dispersion and improving the absorption of drugs.
The term “hyaluronidase” as used herein means any enzyme that degrades hyaluronic acid and lowers the viscosity of hyaluronan in the extracellular matrix. For the avoidance of doubt, the hyaluronidase described herein is not the drug described herein.
In a preferred embodiment, the hyaluronidase is recombinant hyaluronidase. In a particularly preferred embodiment, the hyaluronidase is recombinant human hyaluronidase, e.g. rHuPH20.

In some embodiments of the invention, the hyaluronidase is a variant of rHuPH20 having an amino acid sequence of rHuPH20 that comprises SEQ ID NO: 2, namely residues 36-482 of wild type human hyaluronidase. In some embodiments of the invention, the hyaluronidase is a variant of rHuPH20 having an amino acid sequence that comprises SEQ ID NO: 3. In some embodiments of the invention, the hyaluronidase is a variant of rHuPH20 having an amino acid sequence that comprises SEQ ID NO: 4. In some embodiments of the invention, the hyaluronidase is a variant of rHuPH20 having an amino acid sequence that comprises SEQ ID NO: 5.

Use of the Drug and Hyaluronidase in the Invention
In a first aspect there is provided a method for the treatment or prevention of a disease or disorder in a subject in need thereof, the method comprising administering to the subject a drug effective in the treatment or prevention of the disease or disorder in the form of micro- or nanoparticles in suspension by intramuscular injection or subcutaneous injection, wherein the drug is administered in combination with a hyaluronidase that is administered by intramuscular injection or subcutaneous injection, and wherein the drugand the hyaluronidase are administered intermittently at a time interval of about three months to about two years.
Thus, the method for treatment or prevention described herein involves administering a drug and a hyaluronidase multiple times, and the time interval between an administration of the drug and the hyaluronidase and a subsequent administration of the drug and the hyaluronidase is about three months to about two years, i.e. the drug and hyaluronidase according to the invention is administered to a subject as described herein, and then after a period of from three months to two years the drug and hyaluronidase according to the invention is administered again to the subject as defined herein.
The terms “is administered” and “are administered” as used herein in relation to the methods for treatment or prevention and uses described herein may encompass the terms “is to be administered” and “are to be administered”, respectively.
In a preferred embodiment, the subject is a human.
The drug and the hyaluronidase may be administered simultaneously or sequentially. In an embodiment, the drug and the hyaluronidase are administered sequentially, i.e. one after the other, preferably within 24 hours of each other, preferably within 1 hour of each other, preferably within 30 minutes of each other, preferably within 10 minutes of each other, more preferably within 5 minutes of each other. Preferably, the hyaluronidase is administered before administration of the drug. In another embodiment, the drug and the hyaluronidase are administered simultaneously.
When the drug and the hyaluronidase are administered sequentially, they are formulated in separate pharmaceutical compositions. These separate pharmaceutical compositions are described further in the sections titled “Drug” and “Hyaluronidase” herein.
When the drug and the hyaluronidase are administered sequentially, they are both administered by the same method, i.e. subcutaneous or intramuscular injection. Further, they are both administered at the same site. By same site it is meant that the injection sites are within 15 cm of each other, within 12 cm of each other, or within 8 cm of each other. Preferably the injection sites are within 10 cm of each other, more preferably within 5 cm of each other, even more preferably within 1 cm of each other. This allows the hyaluronidase to exert its effect in increasing the tolerability of the injection of drug, in particular rilpivirine or pharmaceutically acceptable salt thereof or apalutamide.
When the drug and hyaluronidase are administered simultaneously, they may both be administered at the same site, i.e. simultaneously via the same needle. When the drug and hyaluronidase are administered simultaneously, the drug and hyaluronidase may be provided in combined pharmaceutical composition, i.e. a pharmaceutical composition comprising both the drug and the hyaluronidase. This combined pharmaceutical composition is described further in the sections titled “The drug(s) used in the invention” and “Hyaluronidase” herein. When the drug and hyaluronidase are administered simultaneously, the drug and hyaluronidase may also be provided as separate pharmaceutical compositions which are admixed (i.e. to provide an admixed pharmaceutical formulation) extemporaneously prior to administration.
The combined pharmaceutical composition of the invention is surprisingly stable on storage, i.e. the hyaluronidase is active even after being combined with the drug, extemporaneously prior to administration, e.g. for at least 4 hours at room temperature, or for 24 hours or longer, in particular when stored at 2-8° C.
In an embodiment, the drug and the hyaluronidase are administered at the same injection site sequentially, through the same needle that has not been removed from the injection site, e.g. the skin.
The drug and hyaluronidase of the invention are administered such that the time interval between administrations (i.e. the dosing interval) is about three months to about two years. That is, the drug is administered (e.g. simultaneously or sequentially) with the hyaluronidase and then following a time interval of about three months to about two years the drug is administered (e.g. simultaneously or sequentially) with the hyaluronidase again.
It has been found that the extended, sustained or prolonged release of drugs when administered in the form of micro- or nanoparticles in suspension by intramuscular or subcutaneous injection can be maintained when administering the drug with a hyaluronidase as defined herein. This surprising effect is discussed in detail in Examples 1 and 2.
In an embodiment, the time interval described herein is about three months to about 1.5 years. In an embodiment, the time interval described herein is about two years. In a preferred embodiment, the time interval described herein is about three months to about one year. In another preferred embodiment, the time interval described herein is about three months to about six months. In another preferred embodiment, the time interval described herein is about six months to about 1 year. In another preferred embodiment, the time interval described herein is about three months. In another preferred embodiment, the time interval described herein is about six months. In another preferred embodiment, the time interval described herein is about 1 year.
The drug and the hyaluronidase are administered by subcutaneous injection or intramuscular injection. Preferably, the drug and hyaluronidase are administered by subcutaneous injection (either in the same combined pharmaceutical composition or in separate pharmaceutical compositions).
The drug and the hyaluronidase of the invention are used in a method for the treatment or prevention of a disease or disorder in a subject in need thereof, i.e. they are for use in therapy. The drug is administered in a therapeutically effective amount. By “therapeutically effective amount” it is meant an amount sufficient to provide a therapeutic effect.
In a particular embodiment, the drug and the hyaluronidase are used in a method for the treatment of a disease of disorder, in particular for the treatment of HIV infection or for the treatment of cancer, in a subject in need thereof as described herein, wherein the suspension comprises a pharmaceutically acceptable aqueous carrier in which the drug is suspended in the form of micro- or nanoparticles, and the drug and the hyaluronidase are administered by subcutaneous injection, and preferably wherein a surface modifier, e.g. poloxamer 338 or Tween 20, is adsorbed to the surface of the micro- or nanoparticles.
In an embodiment, the drug and hyaluronidase of the invention are for use in a method for the treatment or prevention of chronic and long-term diseases and disorders, for example for treatment of chronic viral infection (such as chronic infection with Varicella-zoster virus, measles virus, HIV, hepatitis B virus, hepatitis C virus, hepatitis D virus or human cytomegalovirus), cancer, psychiatric diseases and disorders, mood disorders (such as bipolar, cyclothymic or depression), diabetes, hypertension, abnormal cholesterol and triglyceride levels, inflammatory disorders (such as allergy, asthma, autoimmune diseases, coeliac disease, hepatitis, inflammatory bowel disease, Crohn disease, gout, myositis, scleroderma, rheumatoid arthritis, lupus vasculitis, ankylosing spondylitis or chronic obstructive pulmonary disease), cystic fibrosis, multiple sclerosis, autoimmune disorders, neurodegenerative disorders (such as Parkinson Disease or Alzheimer disease), chronic pain, inherited metabolic disorders or epilepsy.
In an embodiment, the drug and hyaluronidase of the invention are for use in the treatment or prevention of HIV infection in a subject, i.e. an embodiment described herein relates to a method for treating or preventing HIV infection in a subject using the drug and hyaluronidase as defined herein. In an embodiment, the HIV is HIV type 1 (HIV-1). When the disease or disorder is HIV infection, the drug is preferably rilpivirine or a pharmaceutically acceptable salt thereof, more preferably rilpivirine,
As used herein the term “treatment of HIV infection” relates to the treatment of a subject infected with HIV. The term “treatment of HIV infection” also relates to the treatment of diseases associated with HIV infection, for example AIDS, or other conditions associated with HIV infection including thrombocytopaenia, Kaposi's sarcoma and infection of the central nervous system characterized by progressive demyelination, resulting in dementia and symptoms such as, progressive dysarthria, ataxia and disorientation, and further conditions where HIV infection has also been associated with, such as peripheral neuropathy, progressive generalized lymphadenopathy (PGL), and AIDS-related complex (ARC).
As used herein the term “prevention of HIV infection” relates to the prevention or avoidance of a subject (who is not infected with HIV) becoming infected with HIV. The source of infection can be various, a material containing HIV, in particular a body fluid that contains HIV such as blood or semen, or another subject who is infected with HIV. Prevention of HIV infection relates to the prevention of the transmission of the virus from the material containing HIV or from the HIV infected individual to an uninfected person, or relates to the prevention of the virus from entering the body of an uninfected person. Transmission of the HIV virus can be by any known cause of HIV transfer such as by sexual transmission or by contact with blood of an infected subject, e.g. medical staff providing care to infected subjects. Transfer of HIV can also occur by contact with HIV infected blood, e.g. when handling blood samples or with blood transfusion. It can also be by contact with infected cells, e.g. when carrying out laboratory experiments with HIV infected cells.
The term “treatment of HIV infection” refers to a treatment by which the viral load of HIV (represented as the number of copies of viral RNA in a specified volume of serum) is reduced. The more effective the treatment, the lower the viral load. Preferably the viral load should be reduced to as low levels as possible, e.g. below about 200 copies/ml, in particular below about 100 copies/ml, more in particular below 50 copies/ml, if possible below the detection limit of the virus. Reductions of viral load of one, two or even three orders of magnitude (e.g. a reduction in the order of about 10 to about 102, or more, such as about 103) are an indication of the effectiveness of the treatment. Another parameter to measure effectiveness of HIV treatment is the CD4 count, which in normal adults ranges from 500 to 1500 cells per μl. Lowered CD4 counts are an indication of HIV infection and once below about 200 cells per μl, AIDS may develop. An increase of CD4 count, e.g. with about 50, 100, 200 or more cells per μl, is also an indication of the effectiveness of anti-HIV treatment. The CD4 count in particular should be increased to a level above about 200 cells per μl, or above about 350 cells per μl. Viral load or CD4 count, or both, can be used to diagnose the degree of HIV infection.
The term “treatment of HIV infection” and similar terms refer to that treatment that lowers the viral load, or increases CD4 count, or both, as described above. The term “prevention of HIV infection” and similar terms refer to that situation where there is a decrease in the relative number of newly infected subjects in a population in contact with a source of HIV infection such as a material containing HIV, or a HIV infected subject. Effective prevention can be measured, for example, by measuring in a mixed population of HIV infected and non-infected individuals, if there is a decrease of the relative number of newly infected individuals, when comparing non-infected individuals treated with a pharmaceutical composition of the invention, and non-treated non-infected individuals. This decrease can be measured by statistical analysis of the numbers of infected and non-infected individuals in a given population over time.
In a particular embodiment, the invention relates to a method for the treatment or prevention of HIV infection, preferably HIV type 1 (HIV-1) infection, in a subject in need thereof, the method comprising administering to the subject rilpivirine or a pharmaceutically acceptable salt thereof in the form of micro- or nanoparticles in suspension, as described herein, in combination with a hyaluronidase, particularly rHuPH20, as described herein, wherein the rilpivirine or pharmaceutically acceptable salt thereof and the hyaluronidase are administered to the subject by intramuscular or subcutaneous injection, preferably subcutaneous injection, and wherein the rilpivirine or pharmaceutically acceptable salt thereof and the hyaluronidase are administered intermittently at a time interval of about three months to about two years, preferably about three months to about six months.

The term “comprising” encompasses “including” as well as “consisting”, e.g. a composition “comprising” X may consist exclusively of X or may include something additional, e.g. X+Y. The term “comprising” used herein also encompasses “consisting essentially of”, e.g. a composition “comprising” X may consist of X and any other components that do not materially affect the essential characteristics of the composition.
The term “about” in relation to a numerical value Y is optional and means, for example, Y±10%.
When a time interval is expressed as a specified number of months, it runs from a given numbered day of a given month to the same numbered day of the month that falls the specified number of months later. Where the same numbered day does not exist in the month that falls the specified number of months later, the time interval runs into the following month for the same number of days it would have run if the same numbered day would exist in the month that falls the specified number of months later.
When a time interval is expressed as a number of years, it runs from a given date of a given year to the same date in the year that falls the specified number of years later. Where the same date does not exist in the year that falls the specified number of years later, the time interval runs for the same number of days it would have run if the same numbered day would exist in the month that falls the specified number of months later. In other words, if the time interval starts on 29th February of a given year but ends in a year where there is no 29th February, the time period ends instead on 1st March in that year.
The term “about” in relation to such a definition means that the time interval may end on a date that is ±10% of the time interval.
In an embodiment, the time interval may start up to 7 days before or after the start of the time interval and end up to 7 days before or after the end of the time interval.
All references cited herein are incorporated by reference in their entirety.
The invention will now be described with reference to the following examples. For the avoidance of doubt, this example does not limit the scope of the invention. Modifications may be made whilst remaining within the scope and spirit of the invention.
This example compares the plasma kinetics after administration of a drug suspension with the plasma kinetics following sequential administration of first a hyaluronidase solution then a drug suspension.
Preparation of Drug and Hyaluronidase Compositions
(a) Suspension of Drug
A 3.380 mL fill of 300 mg/mL suspension of rilpivirine (Dv50=˜200 nm) was prepared in 4R glass vials with the following excipients:
The suspension was prepared as follows:
A buffer solution was prepared by dissolving citric acid monohydrate, sodium dihydrogen phosphate monohydrate, sodium hydroxide and, glucose monohydrate in water for injection in a stainless steel vessel. Poloxamer 338 was added to the buffer solution and mixed until dissolved. A first fraction of the poloxamer 338 buffer solution was passed sequentially through a pre-filter and 2 serially-connected sterile filters into a sterilized stainless steel vessel. The sterile drug substance (micronized irradiated) was aseptically dispersed, via a charging isolator, into the sterile solution. The remaining fraction of poloxamer 338 buffer solution was passed sequentially through a pre-filter and 2 serially-connected sterile filters into the milling vessel to make up the suspension concentrate. During and after addition of the drug substance, the suspension concentrate was mixed to wet and disperse the drug substance.
Milling of the Suspension Concentrate
The suspension concentrate in the milling vessel was aseptically milled by circulating through a sterilized stainless-steel milling chamber, using sterilized zirconia beads as grinding media. During the milling process, the suspension circulated between the milling chamber and the milling vessel by means of a peristaltic pump until the target particle size was achieved.
Dilution of the Suspension Concentrate to Final Concentration
