Azura Ophthalmics Secures Grant to Evaluate AZR-MD-001 for Improved Vision Quality Related to Contact Lens Discomfort
August 17, 2022
Funding awarded by Brandon BioCatalyst’s CUREator
Azura Ophthalmics Ltd. (Azura), a clinical-stage biopharmaceutical company developing a new therapeutic class of Ophthalmic Keratolytics for ocular surface diseases, today announced that the company was awarded a grant from CUREator, Australia’s national biomedical incubator managed by Brandon BioCatalyst. The grant will support Azura’s two-stage study evaluating the safety, tolerability and efficacy of the company’s lead clinical candidate, AZR-MD-001, in patients with contact lens discomfort (CLD) who show evidence of Meibomian gland dysfunction (MGD).
“We are excited to be awarded this CUREator grant and believe it further serves to validate our differentiated approach of combining ophthalmologic and dermatologic solutions to exploit the properties of keratolytics to treat the root cause of contact lens discomfort and other ocular surface indications,” said Marc Gleeson, CEO of Azura Ophthalmics. “Meibomian gland dysfunction is the primary cause of CLD and is directly implicated in the eye dryness and discomfort millions of contact lens wearers experience.”
Fiona Stapleton, Scientia Professor, School of Optometry and Vision Science at University of New South Wales Sydney, commented, “We are pleased Azura has been awarded this grant and look forward to continuing our collaborative evaluation of AZR-MD-001 for CLD. Our pilot study met its primary endpoints by showing statistically significant improvements in multiple measures of Meibomian gland secretion and patients’ ability to wear contact lenses as desired.”
Background on AZR-MD-001 in patients with CLD
It is estimated there are 140 million contact lens wearers worldwide and over 44 million wearers in the U.S. alone. Up to 51% of lens wearers ‘‘drop out’’ of contact lens wear citing CLD as the primary reason for discontinuation.1
Azura evaluated AZR-MD-001 ointment (1.0%) as a potential treatment for CLD in an early pilot study: SOVS2019-070 (the ECLIPTIC study). Significant improvements over baseline were observed in meibum gland secretion score (MGS) and number of meibomian glands yielding liquid secretion (MGYLS) following treatment with AZR-MD-001 for 3 months (p < 0.0086 and p < 0.0151, respectively). Analyses from the University of New South Wales (UNSW) conducted by Professor Fiona Stapleton found that AZR-MD-001 showed a statistically significant improvement over baseline in CLDEQ-8 score at 1 and 4 months (p<0.01) and an improvement in the visual symptoms subscale (frequency and severity of fluctuating vision) of the CLDEQ-8 (p=0.02) for the same periods.2 This impact of AZR-MD-001 on visual function was also found in an integrated Phase 2a analysis across four studies conducted by Azura in patients with MGD. Results from the integrated analyses indicated significant drug effects on the Visual Function subscale of the Ocular Surface Disease Index (OSDI).
The significant impact of AZR-MD-001 on visual function observed across the studies is hypothesized to be the result of increasing meibum release and/or production. Increasing meibum release and/or production strengthens the lipid layer of the tear film which in turn should increase the stability of the precorneal tear film. Since the precorneal tear film is the first major refractive surface in the eye, this should stabilize visual quality and could explain the observed improvements in vision-related patient-reported outcomes.
About Meibomian Gland Dysfunction
Meibomian gland dysfunction (MGD) is a chronic and progressive condition associated with blockage of the meibomian glands and alteration in the quality of expressed meibum. It is the leading cause of Dry Eye Disease (DED) and contact lens discomfort (CLD).3,4 MGD is commonly characterized by terminal duct obstruction and/or qualitative/quantitative changes in the glandular secretion.5 There are no approved prescription pharmaceutical agents that specifically treat these glandular changes. If left untreated, MGD will alter the tear film, resulting in damage to the front of the eye and severe discomfort from associated ocular surface diseases.
About Contact Lens Discomfort
Contact lens discomfort (CLD) is a condition where lens wearers experience pain and irritation, causing them to reduce their lens-wearing time or completely stop wearing them. The use of contact lenses can stress the tear film, resulting in instability and alterations of the lipid layer, and can cause symptoms to unexpectedly manifest in patients with mild MGD who are otherwise asymptomatic.6 There are currently no approved pharmacologic treatments for (CLD) and there are no treatments available that can significantly improve the debilitating symptoms associated with CLD such as blurred, fluctuating vision and discomfort.
Azura’s lead clinical-stage drug candidate, AZR-MD-001, is a topical ointment that has been developed to yield properties ideal for ophthalmic use. The formulation is applied to the lower lid margin twice a week before bedtime.
AZR-MD-001 leverages Selenium Sulfide (SeS2) as the active ingredient. SeS2 has been identified to be an ideal candidate for treating Meibomian gland dysfunction (MGD) due to its multi-mechanism of action targeting the pathophysiology of MGD. It breaks down the bonds between abnormal keratin proteins to soften the blockage, slows down the production of keratin to prevent future blockages and increases the quantity of lipid produced by the meibomian glands.
AZR-MD-001 is currently being studied in a Phase 2 trial to evaluate the safety, tolerability and efficacy of the study drug in patients with MGD and Evaporative Dry Eye Disease (DED). Azura expects to report topline data in the fourth quarter of 2022.
