Dr. Todd Brady
Thank you, Josh. Good morning to everyone, and thank you for joining us today. In just a few short weeks, COVID-19 has affected virtually every aspect of our lives. On behalf of everyone at Aldeyra, I want to extend our thoughts to those that have been touched by this devastating illness. Over the past two months, it’s been inspiring to see the selfless commitment of doctors, nurses and other health care professionals working around the clock to extinguish the virus and it’s also been encouraging to witness the collaboration of companies across our industry as they attempt to solve this global health care crisis. Along these lines, I want to thank our own employees for their tireless efforts over the past months regarding our initiatives to treat COVID-19 infection, which I will discuss later in this call. From Aldeyra’s perspective, although, the stay-at-home orders and other government-mandated measures have affected certain of our clinical enrollment time lines, we believe we remain well-positioned to execute on our strategic objectives. As noted in this morning’s press release, we concluded the first quarter with $61.4 million in cash, cash equivalents and marketable securities, and are updating our guidance to extend our projected cash runway into 2022. On our fourth quarter call, we discussed the strategic prioritization of our late-stage ocular disease programs, including our trials in dry eye disease, allergic conjunctivitis and proliferative vitreoretinopathy. Since our fourth quarter call, two events have prompted us to accelerate the development of our systemic disease programs with ADX-629, a first-in-class orally available and irreversible covalent inhibitor of pro-inflammatory RASP. First, was the potential applicability of ADX-629 to mitigate respiratory compromise in patients infected with COVID-19. In preclincal models, ADX-629 and structural analog reproxalap have demonstrated activity in cytokine release syndrome, which is thought to lead to acute respiratory distress and other forms of respiratory compromise that require mechanical intubation in COVID-19 infected patients. Second, in April, we reported positive topline results from our Phase 1 clinical trial of ADX-629. To summarize those findings, ADX-629 was well-tolerated and no treatment adverse events were recorded in the trial at any of the doses tested. Clinically relevant plasma concentrations exceeding known levels of RASP were observed, suggesting that near total RASP inhibition is theoretically possible in plasma and relative to subjects treated with placebo, reduction in the commonly described pro-inflammatory RASP malondialdehyde was observed in drug treated subjects, confirming target engagement. With the success of ADX-629 in Phase 1, we now plan to embark on a comprehensive systemic disease initiative to assess the activity of 629 in three types of severe inflammation, cytokine release syndrome, autoimmune disease and allergy. Our positive Phase 1 data, as mentioned above is supported by strong preclinical evidence, demonstrating that ADX-629 reduced levels of TH1, TH2 and TH17-related cytokines, suggesting potential activity across a broad array of inflammatory diseases. Contingent on FDA review in the third quarter, we plan to initiate a Phase 2 clinical trial of ADX-629 in subjects with COVID-19-associated respiratory compromise. ADX-629, either as a single agent or as an adjunct to other therapies has the potential to reduce levels a broad array of inflammatory cytokines, thereby mitigating respiratory compromise and potentially improving patient outcomes. We are also targeting two Phase 2a clinical trials of ADX-629 for the second half of this year to test the ADX-629 activity in autoimmune and allergic diseases. The first of these planned trials is in patients with psoriasis and autoimmune condition associated with TH1 cytokines. The other planned trial is in patients with atopic asthma, an allergic inflammatory disease associated with TH2 cytokines. Regarding our ocular disease franchise, reproxalap continues to advance toward NDA filing in allergic conjunctivitis and dry eye disease. In dry eye disease, at midyear we have a Type C meeting scheduled with the FDA to review the remaining NDA requirements for reproxalap. Dry eye disease affects approximately 34 million people in the United States and remains inadequately addressed by current therapies. Results from our trials with reproxalap, which include clinically relevant change from baseline in two well-controlled trials, suggest potentially best-in-class rapid onset and broad symptomatic improvement. We plan to update on our clinical development plans in dry eye disease following receipt and review of the FDA feedback. For allergic conjunctivitis, we now expect results from our Phase 3 INVIGORATE trial in the first half of 2021. The timing of trial completion is later than initially planned, primarily due to delays associated with an extended allergy season. As many of you know, allergen chamber trials like INVIGORATE are conducted outside of allergy seasons to avoid the confounding effects of pollen in the environment. Based on the successful Phase 3 ALLEVIATE trial announced last year and assuming continued clinical success and positive regulatory review, reproxalap has the potential to be the first new mechanistic approach in decades for the treatment of allergic conjunctivitis, which affects 66 million patients in the United States, and importantly, is often associated with dry eye disease. As with dry eye disease, we think reproxalap could fill a significant gap in treatment. The current therapeutic landscape of allergic conjunctivitis is generally restricted to antihistamines and corticosteroids. The studies have shown that antihistamines are unsatisfactory for as many as one-third of patients, while chronic use of corticosteroids may lead to potentially serious adverse events. Lack of clinical site availability and staffing due to COVID-19 has delayed patient enrollment in our Phase 3 GUARD trial of ADX-2191 for the prevention of proliferative vitreoretinopathy. We plan to update the enrollment and completion time lines by year-end. At the same time, we are exploring additional indications for ADX-2191, including primary intraocular lymphoma, a rare but serious ocular cancer. With that, I will hand it back over to Josh, who will cover our financial results in detail.
