Aldeyra Therapeutics Announces Top-Line Results from the Phase 3 TRANQUILITY Trial in Dry Eye Disease
Aldeyra Therapeutics, Inc. (Nasdaq: ALDX) (Aldeyra or the Company), a biotechnology company developing novel immune-modulating therapies to treat ocular and systemic diseases, today announced top-line results from the Phase 3 TRANQUILITY Trial of 0.25% reproxalap ophthalmic solution (reproxalap), an investigational product candidate for the treatment of dry eye disease.
Although the primary endpoint of ocular redness was not met in TRANQUILITY, statistical significance (p=0.0001) was achieved for the dry eye disease sign of Schirmer test, a secondary endpoint. Statistical significance (p<0.0001) was also achieved for the post-hoc assessment of Schirmer test responders of ≥10 mm. The Schirmer test has been accepted by the U.S. Food and Drug Administration (FDA) as part of the basis of approval of other dry eye disease products. The primary endpoint of the upcoming Phase 3 TRANQUILITY-2 Trial has been modified such that the endpoint will have been met if either Schirmer test or ocular redness demonstrates stastisical significance. In addition, target enrollment in TRANQUILITY-2 has been increased from 300 to up to 400 patients. Top-line results from TRANQUILITY-2 are expected mid-2022.
“Following the achievement of statistical significance in ocular redness in our recent Phase 2 clinical trial, the achievement of statistical significance of Schirmer test in TRANQUILITY may provide an additional option to satisfy the remaining objective sign requirement for dry eye disease NDA submission,” stated Todd C. Brady, M.D., Ph.D., President and Chief Executive Officer of Aldeyra. “Subject to agreement with the FDA, we believe that the TRANQUILITY results allow for the possibility that, pending the outcome of TRANQUILITY-2, the NDA submission for reproxalap could represent the first time a dry eye disease drug will have qualified for the demonstration of activity for two objective signs.”
Per draft FDA guidance, to be considered for regulatory approval in the United States, a product candidate for the treatment of dry eye disease must demonstrate efficacy in an objective sign in at least two clinical trials and efficacy in a subjective symptom in at least two clinical trials. To satisfy the symptom efficacy requirements, Aldeyra intends to submit two previously completed 12-week adequate and well-controlled symptom trials that pre-specified patient-reported ocular dryness score as a primary endpoint, the Phase 3 RENEW-Part 1 Trial and the Formulation Phase 2 clinical trial. Aldeyra’s recently completed Phase 2 clinical trial achieved the primary endpoint of ocular redness, an approvable sign of dry eye disease. Pending discussion with the FDA and the results of TRANQUILITY-2, Aldeyra may submit two pivotal trials for either ocular redness (Phase 2 and TRANQUILITY-2) or Schirmer test (TRANQUILITY and TRANQUILITY-2), or two trials for both signs (Phase 2, TRANQUILITY, and TRANQUILITY-2) if ocular redness and Schirmer test are achieved in TRANQUILITY-2. Phase 2 and Phase 3 clinical trials can be submitted as pivotal, provided that the trials are adequate and well-controlled.
