Tonix Pharmaceuticals Presented Data from Two Posters on TNX-102 SL for Reduction of Acute Stress Reaction and Prevention of PTSD and One Poster for Wound Healing at the 2024 Military Health System Research Symposium (MHSRS)

Rhea-AI Summary

Tonix Pharmaceuticals (TNXP) presented data on TNX-102 SL for acute stress reaction (ASR) and PTSD prevention at the 2024 Military Health System Research Symposium. An investigator-initiated Phase 2 trial to evaluate TNX-102 SL's potential to reduce ASR severity and prevent PTSD is expected to begin in Q3 2024. The OASIS trial will enroll about 180 trauma survivors at emergency departments, randomizing them to receive TNX-102 SL or placebo for two weeks after motor vehicle collisions.

TNX-102 SL showed effects on sleep and PTSD symptoms in previous military-related PTSD trials. The company believes early intervention with TNX-102 SL could reduce ASR symptoms and prevent PTSD development. Tonix also presented data on an automated high-throughput assay for screening wound healing therapeutics.

Medical Research Analyst

This news highlights Tonix Pharmaceuticals' progress in developing TNX-102 SL for acute stress reaction (ASR) and PTSD prevention. The upcoming OASIS trial, set to begin in Q3 2024, is particularly noteworthy. It will test TNX-102 SL's efficacy in reducing ASR severity and preventing PTSD when administered within 24 hours of trauma.

The potential impact is significant, as currently no medication is approved for immediate post-trauma treatment. Previous trials have shown TNX-102 SL's positive effects on sleep quality and PTSD symptoms, which could be important in preventing long-term psychological issues. The $40 million AURORA initiative provides a strong foundation for this research.

However, investors should note that while promising, the drug is still in clinical trials. FDA approval, if achieved, would likely be years away. The market potential is substantial, given that 60% of men and 50% of women experience trauma in their lives, but competition and regulatory hurdles remain significant factors to consider.

Financial Analyst

Tonix Pharmaceuticals' focus on TNX-102 SL for ASR and PTSD prevention represents a potentially lucrative market opportunity. The lack of approved medications in this space could position Tonix as a first-mover if successful. The company's recent $34 million contract with the DoD for a separate antiviral agent (TNX-4200) demonstrates its ability to secure government funding, which could be a positive indicator for future collaborations.

However, investors should be cautious. Tonix's financial position and burn rate are important factors to consider, especially given the long development timelines in pharmaceuticals. The company's diversified pipeline, including fibromyalgia and cocaine intoxication treatments, may provide some risk mitigation. The recent acquisition of commercial products (Zembrace SymTouch and Tosymra) could potentially generate revenue to support R&D efforts.

Overall, while the news is positive, it's important to balance the long-term potential against the near-term financial realities and risks inherent in drug development.

Investigator-initiated Phase 2 trial to evaluate TNX-102 SL’s potential to reduce severity of acute stress reaction (ASR) and frequency of acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) expected to begin third quarter 2024

Currently, no medication approved at or near point-of-care to treat patients suffering from traumatic events and support their long-term health

CHATHAM, N.J., Aug. 29, 2024 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a fully-integrated biopharmaceutical company with marketed products and a pipeline of development candidates, presented clinical data on? acute stress reaction and prevention of PTSD data of TNX-102 SL in two poster presentations and presented preclinical data demonstrating automated high-throughput assay enabling screening for therapeutics to accelerate wound healing in a third poster presentation at the 2024 Military Health System Research Symposium (MHSRS), held August 26-29, 2024, in Kissimmee, Fla. Copies of the Company’s posters, titled:

“Two Clinical Trials of Bedtime Sublingual Cyclobenzaprine (TNX-102 SL) in Military-Related Posttraumatic Stress Disorder (PTSD) Provide Rationale to Study TNX-102 SL in the Aftermath of Trauma to Reduce Acute Stress Disorder (ASD) and Prevent PTSD”;

“Development of the AURORA Platform Trial Network to Test Interventions to Reduce Acute Stress Reaction Symptoms, and Illustration of Use Testing Sublingual Cyclobenzaprine TNX-102 SL”;

“Integrating Automated High-Throughput Scratch Assay and Cell Painting for Comprehensive Analysis of Cell Migration and Wound Healing”, are available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com.

TNX-102 SL is being evaluated for the reduction in severity of acute stress reaction (ASR) and the frequency of acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) when administered within 24 hours of trauma event. In two double-blind, randomized clinical trials of military-related PTSD, TNX-102 SL showed effects on sleep and PTSD symptoms in two and four weeks of treatment¹. Supportive data on the effects of TNX-102 SL on reducing PTSD symptoms suggest early intervention immediately after trauma using TNX-102 SL has the potential to reduce ASR/ASD symptoms which are similar to those of PTSD^2,3. TNX-102 SL has been well-tolerated with no recognized liability for tolerance or abuse. Data from these trials support testing of TNX-102 SL within 24 hours of index trauma for effects on acute stress reaction (ASR) symptoms and the incidence of PTSD. In the U.S. Department of Defense-funded Optimizing Acute Stress Reaction Interventions (OASIS) trial conducted by the University of North Carolina under an investigator-initiated investigational new drug (IND) application, 14 days of bedtime TNX-102 SL will be dosed and tested in the immediate aftermath of motor vehicle collision. The study will test the potential for TNX-102 SL to target trauma-related sleep disturbance and its ability to facilitate recovery from ASR and to prevent PTSD. The results may ultimately provide military personnel with a new treatment option that, when administered in the early aftermath of a traumatic event to individuals with ASR symptoms, improves warfighter function.

“In previous trials, TNX-102 SL has been shown to improve sleep quality in PTSD and increased activity on sleep and stress-related symptoms in the first several weeks of treatment after a trauma event”, said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Since sleep disturbance plays a critical role in the development and maintenance of PTSD, sleep improvements may reorient the trajectory of posttraumatic pathology from acute trauma towards early recovery. The OASIS study is driven by the observation that the symptoms of ASR and PTSD are similar and by the hypothesis that TNX-102 SL’s effect on sleep quality may reduce ASR symptoms, potentially providing military personnel, veterans, and civilians with a new treatment option that, when administered in the early aftermath of a traumatic event, improves recovery, job performance, and quality of life.”

The investigator-initiated OASIS trial will examine the safety and efficacy of TNX-102 SL to reduce adverse posttraumatic neuropsychiatric sequelae among patients presenting to the emergency department (ED) after a motor vehicle collision. The trial plans to enroll approximately 180 trauma survivors at ED study sites around the U.S. Participants will be randomized in the ED to receive a two-week course of either TNX-102 SL 5.6 mg or placebo. The first participant for the OASIS trial is expected to enroll in the third quarter of 2024.

The OASIS trial will build upon a foundation of knowledge and infrastructure developed through the UNC-led, $40 million AURORA initiative. AURORA is a major national research initiative to improve the understanding, prevention and recovery of individuals who experience a traumatic event. AURORA is supported by funding from the National Institutes of Health (NIH), leading brain health nonprofit One Mind, private foundations, and partnerships with leading tech companies, such as Mindstrong Health and Verily Life Sciences, the healthcare arm of Alphabet, the parent company of Google.

Acute and chronic stress disorders can affect both civilian and military populations. According to the National Center for PTSD, in the U.S. about 60% of men and 50% of women experience at least one trauma in their lives.⁴ In the U.S. alone, one-third of ED visits (40-50 million patients per year) involve evaluation after trauma exposures, and in a 2014 study involving 3,157 US veterans, 87% reported exposure to at least one potentially traumatic event during their service.⁵ Moreover, as many as 500,000 U.S. troops who served in wars between 2001 and 2015 were diagnosed with PTSD.⁶

The third poster, titled “Integrating Automated High-Throughput Scratch Assay and Cell Painting for Comprehensive Analysis of Cell Migration and Wound Healing”, demonstrated optimization of a highly efficient scratch-wound assay development method. The scratch-wound assay, commonly used to study wound healing, has limitations that the study addresses by introducing an automated miniaturized high-throughput wound healing assay, enabling mass screening and identification of novel therapies for wound-healing. The screening technology was merged with cell-painting to allow discovery of morphological characteristics to identify mechanism of action of drugs for wound healing.
