CHATHAM, N.J., June 03, 2024 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals, Inc. (Nasdaq: TNXP) (Tonix or the Company), a fully-integrated biopharmaceutical company with marketed products and a pipeline of development candidates, presented new data from the Phase 3 RESILIENT trial of Tonmya (TNX-102 SL, cyclobenzaprine HCl sublingual tablets) for the management of fibromyalgia in an oral presentation at the American Society of Clinical Psychopharmacology (ASCP) Annual Meeting on May 29, 2024 in Miami Beach, Fla. A copy of the presentation is available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com.
In the oral presentation titled, “Effects of Bedtime TNX-102 SL (Sublingual Cyclobenzaprine HCl) on Mood and Anxiety Symptoms in Fibromyalgia: Results of the Phase 3 RESILIENT Trial,” Seth Lederman, MD, Chief Executive Officer, presented new data suggesting activity for improvement in depressive symptoms with Tonmya.
Depression was frequent among patients enrolled in the RESILIENT trial: ~47% reported experiencing depression within the past 6 months upon fibromyalgia diagnosis and ~25% of the intent-to-treat (ITT) population had experienced a lifetime major depressive episode (MDE). The effect of Tonmya on depressive symptoms was studied using the Beck Depression Inventory-II (BDI-II). Patients started with a baseline mean (standard deviation) for placebo of 10.0 (6.72) and Tonmya of 9.6 (6.32). The BDI-II score separated at Week 2 with a nominal p-value of <0.01. By Week 14, the total BDI-II score in the TNX-102 SL group improved over placebo with a nominal p-value of 0.005 and an effect size of 0.27.
Dr. Lederman said, “Although pain is the prototypic symptom in fibromyalgia and the validated FDA endpoint for the approval of a new drug, depression severity is also a prominent factor in the quality of life for fibromyalgia sufferers. In one study, depressive symptoms had a higher correlation with impaired quality of life than any other symptom, including pain frequency and intensity.2 The improvement in depression observed in the Phase 3 RESILIENT was particularly striking since the mean entry score of 10 reflects mild depression. Others have struggled to show benefits of traditional antidepressants in mild depression and consequently many antidepressants have been studied in moderate or severely depressed patients and the benefits of such drugs for patients with mild depression have been inferred.”
Dr. Lederman continued, “In addition to the BDI-II score, in post hoc analyses several individual items on the Fibromyalgia Impact Questionnaire-Revised (FIQR) also improved in the Tonmya-treated group, including : depression (p < 0.001), anxiety (p = 0.001), sensitivity (p = 0.020), memory problems (p = 0.001) and energy (p < 0.001), for which these p-values were not corrected for multiplicity. Together these findings indicate that Tonmya has broad-spectrum activity against fibromyalgia symptoms and may improve fibromyalgia at the syndromal level.”
In the RESILIENT trial, as previously reported, Tonmya improved overall daily pain (p=0.00005), the pre-specified primary endpoint, making it the second Phase 3 study of Tonmya in the management of fibromyalgia to reach statistical significance on the pre-specified primary endpoint. Tonmya also demonstrated statistically significant and clinically meaningful results in all six pre-specified key secondary endpoints including those related to improving sleep quality, reducing fatigue, and improving patient global ratings and overall fibromyalgia symptoms and function.”
In the RESILIENT trial, there were no new safety signals, low rates of systemic adverse events, and a favorable tolerability profile.
Tonix remains on track to submit an NDA to the U.S. Food and Drug Administration (FDA) in the second half of 2024 for Tonmya for the management of fibromyalgia and has scheduled a Type B pre-NDA meeting with FDA for the second quarter of 2024.
