Description

[0001] METHODS AND COMPOSITIONS FOR OCULAR APPLICATION CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to U.S. Provisional Application No. 63 / 737,187, filed December 20, 2024, the entire contents of which are hereby incorporated by reference.

[0002] TECHNICAL FIELD

[0003] This disclosure relates to ophthalmological compositions comprising etiprednol, for treatment of ocular inflammatory conditions, dry eye diseases, and abnormal corneal neovascularization, and methods for using the compositions.

[0004] BACKGROUND

[0005] Millions of people worldwide suffer from vision changes, discomfort, or symptoms related to ocular inflammatory conditions, dry eye diseases, and abnormal corneal neovascularization. Conventional steroids can sometimes relieve the symptoms of these diseases and may also provide effective treatment; however, conventional steroids can cause side effects, including, in some cases, systemic effects. In addition, steroids can be difficult to formulate for ocular delivery. There are limited treatments available for many of these eye diseases. Thus, there is a need for a widely available and effective treatment to help relieve these conditions and symptoms.

[0006] SUMMARY

[0007] This disclosure relates to compositions for ophthalmological use, comprising etiprednol, or a derivative, analogue, racemic mixture, or diastereomer or enantiomer thereof, and methods using the compositions, such as methods for treating or slowing the progression of, or reducing one or more symptoms of, an ocular condition in a subject such as, e.g., ocular inflammatory condition, dry eye disease, or abnormal corneal neovascularization. This disclosure is based in part on a surprising realization that the compositions described herein, containing etiprednol, can provide similar therapeutic effectiveness as compared to conventional corticosteroids, while also limiting the side effects and systemic effects as compared to conventional corticosteroids, and the surprising realization that etiprednol can be formulated in a manner that is stable and effective for ocular delivery.

[0008] Glucocorticosteroids are potent drugs that are usually effective against inflammatory diseases of the body, due to their anti-inflammatory action. However, such conventional glucocorticosteroids bring side effects, especially when administered chronically. Locally-delivered glucocrticosteroids also bring unwanted side effects, both locally, and systemically. Attempts to avoid the unwanted side effects have brought development of so-call "soft steroids", which are more easily metabolized into inactive metabolites, thus making it possible to limit the drug effects to locally administered sites. These are delivered close to their site of action and quickly metabolized to reduce systemic exposure and limit unwanted side effects. One example of a first generation soft steroid is loteprednol, which has previously been used in ocular treatment. However, despite the soft nature of this steroid, loteprednol still presents safety concerns around systemic and unwanted side effects. For example, the FDA-approved ocular use of loteprednol is limited to 14 days due to the safety concerns.

[0009] Etiprednol, developed for asthma treatment, is a second generation soft steroid and is a softer steroid than loteprednol. However, with this very soft steroid, comes challenges, including whether the etiprednol is too soft to exhibit therapeutic activity, as well as whether etiprednol is too labile to be formulated for certain delivery routes, such as ocular delivery, and whether etiprednol is too easily metabolized in an ocular environment so as to lose efficacy in that environment. The Applicant has surprisingly found that etiprednol is safe to use in the eye, and exhibits lower side effect potential than loteprednol and other steroids. Applicant has further surprisingly found that, despite the very soft nature of etiprednol, it is indeed active and effective in treating the ocular conditions described herein. Applicant has further surprisingly found that etiprednol can be formulated in a stable composition for ocular delivery and preferentially delivered transcomeally, despite the instability and labile nature of etiprednol.

[0010] This disclosure provides compositions comprising etiprednol. In some optional instances, this disclosure provides compositions comprising etiprednol and a semifluorinated alkane (SFA) compound, and, optionally, an additive selected from paraffin, medium chain triglycerides (MCT), propylene glycol diacetate (PGD), a semi-fluorinated alkyl alcohol (SFAOH), a hydroxyalkyl ester of an aliphatic fatty acid, a hydroxyacid alkyl ester, an alkyl ester of a fatty acid, phenethyl alcohol, ethanol, isopropanol, glycerol, propylene glycol, propylene glycol dilaurate, polyethylene glycol, n-butanol, and combinations thereof, and methods for making and using the compositions. The compositions described herein can provide efficacy with improved reduction in side effects and systemic effects as compared to conventional corticosteroid treatments. The compositions can also provide stable delivery of etiprednol, and, in some instances, selective transcorneal delivery of etiprednol. In some instances, the etiprednol in the composition can be chemically stable for at least 1 month, at least 2 months, at least 3 months, at least 6 months, at least 9 months, at least 1 year, at least 18 months, at least 2 years or longer.

[0244] Example 2: Etiprednol in a dry eye disease (DED) model

[0245] Etiprednol dicloacetate is tested in a murine DED model as described in De Paiva 2006 to determine its ability to improve DED.

[0246] Model establishment:

[0247] Dry eye is induced in C57BL / 6 mice, aged 6 to 8 weeks, by subcutaneous injection of 0.5 mg / 0.2 mL scopolamine hydrobromide (Sigma- Aldrich, St. Louis, MO) in alternating hindquarters administered four times a day (8 AM, 11 AM, 2 PM, and 5 PM) and by exposure to an air draft and less than 40% ambient humidity for 18 hours per day, as previously reported.

[0248] Treatments:

[0249] • Normal untreated control (no dry eye induction and no topical treatment);

[0250] • DED control (dry eye induced and received no eye drops);

[0251] • Saline control (dry eye induced and received saline eye drops, 1 pl / eye bilaterally, 4 time / day);

[0252] • Etiprednol dicloacetate (dry eye induced and received saline eye drops, 1 pl / eye bilaterally, 4 time / day)

[0253] Measurements:

[0254] After two weeks of treatment, the corneal permeability and smoothness scores are assessed as described by De Paiva 2006 and Pflugfelder 2005.

[0255] Example 3: Etiprednol dicloacetate in a corneal neovascularization model Etiprednol dicloacetate is tested in a rabbit corneal neovascularization model as described in Ribeiro 2012 to determine its ability to suppress corneal neovascularization.

[0256] Model establishment:

[0257] The inflammatory corneal angiogenesis model is induced by punctual alkaline cauterization as described (Ribeiro 2012). After the animals are anesthetized, eyelids are held apart with a blepharostat, exposing almost the entire corneal surface and the upper limbal area. The rabbits are submitted to a punctual cauterization on the top periphery of the right cornea with the aid of a microscope, using a magnification of 16-X by using a circular piece of filter paper (3 mm diameter), previously soaked in a solution of sodium hydroxide (NaOH) 1 M for 30 s (excess solution is blotted away with gauze). The filter paper is left for 2 min at approximately 1 mm from the conjunctival limbal tissue in the 12-o’clock position near the insertion of the upper rectus muscle. The eye is subsequently rinsed with 5 ml sodium chloride at 0.9% solution to remove excess NaOH. The technique produced a 3.5-mm-wide, homogeneous and circular cauterization site with well-defined borders. The animals are returned to their cages only after complete emergence from anesthesia.

[0258] Treatments:

[0259] The rabbits are randomly allocated to three treatment groups: a vehicle group, consisting of 6 rabbits that are treated with 1 drop (40 μl) of the vehicle eyedrop, instilled in the conjunctival sac 3 times per day; a positive control group, consisting of 6 rabbits that are treated with topical instillation of 1 drop (40 μl) of loteprednol etabonate (LE) 0.5% eyedrop 3 times per day; a Etiprednol dicloacetate group, composed of 6 rabbits that are treated with 1 drop (40 μl) of Etiprednol dicloacetate 0.5% in the conjunctival sac 3 times per day. Treatments are initiated on the day of cauterization (day zero) and continued for 21 days.

[0260] Measurements:

[0261] On days 3, 9, 15 and 21, digital photos of the eyes are obtained, and the vascular area on cornea is measured with the ImageJ software.

[0262] Example 4: Ocular Pharmacokinetics of Etiprednol Dicloacetate

[0263] The ocular pharmacokinetics of Etiprednol Dicloacetate and Loteprednol Carbonate are evaluated via a single topical ocular dosing of 0.25% Etiprednol Dicloacetate and 0.25% Loteprednol Carbonate in rabbits.

[0264] Rabbits are randomly assigned to two treatment groups. After gentle shaking, a single 12 microliter drop of either 0.25% Etiprednol Dicloacetate or 0.25% Loteprednol Carbonate formulation is administered to both eyes of each rabbit. At each of the following time points, 0.083, 0.25, 0.5, 1, 2, 4, 8, and 24 hour post dosing, three rabbits from each treatment group are euthanized by intravenous barbiturate overdose and plasma samples are obtained. Both eyes from each rabbit are harvested, and samples are collected from aqueous humor, vitreous humor, cornea, conjunctiva, iris / ciliary body, retina / choroid and sclera. All samples are assayed using liquid chromatography-tandem mass spectrometry (LC-MS / MS). The analysis for each matrix is performed separately and tissue-specific standard curves are generated separately for both formulations.

[0265] Plasma and aqueous humor samples are diluted with control plasma or aqueous humor, respectively, and analyzed directly. Ocular tissue samples are weighted, homogenized, and diluted with methanol prior to analysis. The lower limit of quantitation is 0.4 ng / (g or mL).

[0266] Example 5: Stability of Etiprednol in Exemplary

[0267] Various formulations of Etiprednol were prepared as described in Example 1 above. Concentration of Etiprednol was determined and recorded on Day 0. The compositions were then divided and placed into storage at three different storage temperatures. The concentration of Etiprednol was determined after 1 month, 2 months, 3, months, 6 months, 9 months, and 12 months.
