(Nasdaq: TNXP), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced topline results from the Phase 2 proof-of-concept double-blind, randomized, multi-center, placebo-controlled UPLIFT study of TNX-601 ER* (tianeptine hemioxalate extended-release tablets) in patients with major depressive disorder (MDD). The primary efficacy endpoint of change from baseline in depression severity, as measured by the Montgomery-Åsberg Depression Rating Scale (MADRS) total score, did not achieve clinical or statistical significance. “Based on these efficacy results, we are discontinuing development of TNX-601 ER. We look forward to topline results from our Phase 2 study of TNX-1900 in chronic migraine in early December and topline results from our Phase 3 potential NDA-enabling study of TNX-102 SL in fibromyalgia in late December,” said Seth Lederman, M.D., President and Chief Executive Officer of Tonix Pharmaceuticals. “We would like to thank the patients, their families, and all the investigators and researchers who participated in the Phase 2 UPLIFT study.” In the Phase 2 UPLIFT study, TNX-601 ER was orally administered as monotherapy once a day to 132 patients who, upon entering the study, met a DSM-5 diagnosis of moderate-to-severe depression with a duration for the current major depressive episode of at least 12 weeks. Efficacy was assessed using the MADRS to measure any potential change in patients’ depression severity from baseline. In the study, TNX-601 ER was generally well-tolerated with a favorable safety profile. There was one serious adverse event (SAE) experienced in the placebo group, and two SAEs in the active treatment group deemed possibly related to study drug, both of which resolved without sequelae.
