| Company to Host Conference Call Today, December 7, 2022, at 5:00 PM ET CORAL GABLES, Fla., Dec. 7, 2022 /PRNewswire/ -- Relmada Therapeutics Inc. (Nasdaq: RLMD), a late-stage biotechnology company addressing diseases of the central nervous system (CNS), today announced results of the RELIANCE I study (REL-1017-301), evaluating REL-1017 as an adjunctive treatment for Major Depressive Disorder (MDD). The same factors that negatively affected the previously announced results from the RELIANCE III study, a limited number of high enrolling sites with unplausible placebo response, also affected RELIANCE I and the study did not achieve its primary endpoint, which was a statistically significant improvement in depression symptoms compared to placebo as measured by the Montgomery-Asberg Depression Rating Scale (MADRS) on Day 28. RELIANCE I evaluated the use of REL-1017 in addition to a standard antidepressant for patients who had inadequate response to at least one and up to three standard antidepressant therapies.
In the study, the REL-1017 treatment arm (n= 113) showed a MADRS reduction of 15.1 points at Day 28 versus 12.9 points for the placebo arm (n=114), which is a clinically meaningful difference of 2.2 points on the MADRS, as well as a statistically significant difference in the response rate, with a response rate of 27.2% on placebo vs 39.8% in the REL1017 arm (p<0.05). As was observed in the monotherapy study RELIANCE III (Study 303), implausible results were again observed in two of the same high enrolling RELIANCE I (Study 301) study centers, where placebo dramatically outperformed REL-1017. While the patient population in RELIANCE I was different than RELIANCE III in that subjects enrolled should already have been diagnosed with depression and did not respond adequately to at least one, and up to three courses of antidepressant therapy, a limited number of the same high enrolling centers had implausible rapid and sustained placebo response rates that outperformed REL1017. In a post-hoc analysis of RELIANCE 1 (301 Study) that excluded the same two high enrolling centers that showed implausible placebo response in both REL-1017 studies, the REL-1017 treatment arm (n=97) showed a MADRS reduction of 16.7 points at Day 28 versus 12.6 points for the placebo arm (n=88), a 4.1 point difference, with a p<0.02. A second post-hoc confirmatory analysis, using the well-established band-pass method (Merlo-Pich et al, 2010¹), that excludes patients from those centers with implausible responses in the placebo arm (centers with a placebo response less than 3% from baseline and more than 33% from baseline) showed a robust difference between REL-1017 and placebo. REL-1017, as it did in RELIANCE III, demonstrated very favorable tolerability and safety in RELIANCE I, again confirming the results of Phase 1 and Phase 2 studies (Fava et al, 2022²), with no opioid-like effects, no withdrawal effects, and no psychotomimetic effects. Relmada continues to enroll patients in RELIANCE II, the second ongoing Phase 3, two-arm, placebo-controlled, pivotal study evaluating REL-1017 as a potential adjunctive treatment for MDD. Based on the results of RELIANCE I and RELIANCE III, Relmada is applying several protocol and operational changes to RELIANCE II and making certain improvements to how the trial is being conducted. The RELIANCE development program also includes RELIANCE-OLS, a long-term open-label safety study that is evaluating rollover participants from all three pivotal studies, as well as de novo participants. Conference Call and Webcast Information Relmada will host a conference call and webcast presentation today, December 7, 2022, at 5:00 PM Eastern Time to discuss the study results, which can be accessed with the information below: Wednesday, December 7, 2022, at 5:00 PM ET Domestic: 1-877-407-0792 The subsequent archived recording will be available on the Investors section of the Relmada website at www.relmada.com.

About REL-1017 REL-1017, a new chemical entity (NCE) and novel NMDA receptor (NMDAR) channel blocker that preferentially targets hyperactive channels while maintaining physiological glutamatergic neurotransmission, is currently in late-stage development for the treatment of major depressive disorder (MDD). The ongoing Reliance Clinical Research Program is designed to evaluate the potential for REL-1017 as a rapid-acting, oral, once-daily antidepressant treatment. In a Phase 2 trial, REL-1017 demonstrated rapid, robust, and sustained antidepressant effects with statistically significant improvements compared to placebo. The Phase 2 study also showed a favorable pharmacokinetic, safety, and tolerability profile of REL-1017 consistent with results observed in previously completed Phase 1 studies.
