Top-Line Results from First of Two Planned Clinical Trials Based on Tear RASP Levels Expected by the End of 2020
New Drug Application Submission for Reproxalap in Dry Eye Disease Expected by the End of 2021
Based on Current Operating Plans, Current Cash Expected to Support Operations into 2022, Consistent with Prior Guidance
Aldeyra Therapeutics, Inc. (Nasdaq: ALDX) (Aldeyra), a clinical-stage biotechnology company focused on the development of novel therapies with the potential to improve the lives of patients with immune-mediated diseases, today announced development plans to support a New Drug Application (NDA) for the novel investigational reactive aldehyde species (RASP) inhibitor reproxalap in dry eye disease. Based on U.S. Food and Drug Administration (FDA) meeting minutes, Aldeyra intends to initiate two clinical trials to assess the activity of reproxalap in reducing tear levels of RASP, pro-inflammatory mediators recently accepted by the FDA as an objective sign of dry eye disease.
Top-line results from the first of the RASP trials are expected by the end of 2020, pending potential disruptions due to the COVID-19 pandemic. In addition, a safety trial in dry eye disease patients is expected to be initiated in the fourth quarter of 2020. NDA submission is expected in late 2021.
"Aldeyra’s written meeting minutes with the FDA confirming the use of RASP as an objective sign for the treatment of dry eye disease is a positive step in the regulatory science of novel treatments for ocular surface disease," stated Gary D. Novack, Ph.D., Professor of Ophthalmology at the School of Medicine at University of California, Davis, President of PharmaLogic Development, Inc., and Chair of the Tear Film and Ocular Surface Society DEWS (Dry Eye Workshop) II Clinical Trial Design Group. "RASP assessment is a measurement of the mechanism of action of reproxalap, and represents a potentially important biomarker-based approach. This announcement comes in a context where we have few biomarkers in pharmacotherapy for ocular diseases, and no regulatory-based biomarkers in the treatment of ocular surface disease."
Assessment of RASP in the two planned trials is expected after single and multiple doses of drug over two days. Investigational new drug reproxalap covalently binds RASP via a series of reactions that occur rapidly in vitro, and statistically reduced RASP levels in the tears of dry eye patients in a Phase 2a clinical trial.
Aldeyra also reiterated financial guidance that, based on current operating plans, cash, cash equivalents, and marketable securities are sufficient to support operations into 2022, including completion of the two planned RASP trials and the company’s second Phase 3 clinical trial in allergic conjunctivitis, the INVIGORATE Trial.
"With only one drug approved in the United States for the treatment of the symptoms and signs of dry eye disease, the need for therapeutic options with new mechanisms of action is substantial," stated Todd C. Brady, M.D., Ph.D., President and Chief Executive Officer of Aldeyra. "Reproxalap is a first-in-class investigational RASP inhibitor that, in the Phase 3 RENEW-1 Trial, demonstrated potential rapid and broad symptom control we believe is an important commercial differentiator."
RASP (reactive aldehyde species) are pre-cytokine pro-inflammatory mediators that are elevated in the tears of patients with dry eye disease,1 and correlate with dry eye disease symptoms and signs.2 RASP covalently bind to cellular biomolecules, altering molecular function and activating numerous pro-inflammatory pathways implicated in human disease.
Reproxalap is a novel investigational small-molecule immune-modulating covalent inhibitor of RASP in development as a topically administered ophthalmic solution for dry eye disease and allergic conjunctivitis. The mechanism of action of reproxalap has been validated with the demonstration of statistically significant and clinically relevant activity in multiple late-phase clinical trials.
About Aldeyra Therapeutics
Aldeyra Therapeutics is a clinical-stage biotechnology company focused on the development of novel therapies with the potential to improve the lives of patients with immune-mediated diseases. Two of the company’s lead compounds, reproxalap and ADX-629, target reactive aldehyde species (RASP), which are elevated in ocular and systemic inflammatory disease, leading to elevated levels of cytokine release via activation of a broad array of inflammatory factors, including NF-κB, inflammasomes, and Scavenger Receptor A. Reproxalap is being evaluated in Phase 3 clinical trials in patients with dry eye disease and allergic conjunctivitis. The company’s clinical pipeline also includes ADX-2191, a dihydrofolate reductase inhibitor in Phase 3 testing for proliferative vitreoretinopathy, and ADX-1612, a chaperome inhibitor in Phase 2 testing for COVID-19 and ovarian cancer.
