The recent FDA clearance of the IND application for the Phase 2 OASIS trial to evaluate TNX-102 SL in acute stress reaction (ASR) and potential progression to acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) represents a significant stride in the field of psychopharmacology. The focus on early intervention post-trauma is a paradigm shift from the traditional management of PTSD, which often involves delayed treatment after symptom establishment. Early pharmacological intervention could potentially alter the trajectory of stress-related psychopathology, leading to improved long-term outcomes for trauma survivors.

From a research perspective, the use of TNX-102 SL, a sublingual formulation designed to improve sleep quality—a core issue in stress-related disorders—highlights the importance of addressing sleep disturbances as a gateway to mitigating broader neuropsychiatric sequelae. The trial's design, leveraging the AURORA initiative's extensive data collection, enables a more nuanced understanding of the interplay between trauma, sleep and stress disorders. The outcomes of this trial could have significant implications for the standard of care in both civilian and military trauma response, potentially reducing the long-term societal and economic burden of PTSD.

The economic implications of the OASIS trial are multifaceted. On one hand, the potential for TNX-102 SL to prevent the progression from ASR to ASD and PTSD could translate into substantial healthcare savings by reducing the need for long-term mental health services, medication and the associated indirect costs such as lost productivity and disability claims. On the other hand, the initial investment by the Department of Defense and collaborations with tech companies indicate a strong interest in not only the therapeutic potential but also the economic viability of early intervention strategies.

Moreover, the burden of trauma-related disorders on the healthcare system is immense, with emergency department visits for trauma exposures reaching tens of millions annually in the U.S. alone. If TNX-102 SL proves effective, it could lead to a paradigm shift in the acute management of trauma, potentially becoming a standard treatment protocol in emergency departments nationwide. This would create a significant market for Tonix Pharmaceuticals, affecting stock valuations and investor interest in the company and its pipeline.

The pharmaceutical industry closely monitors the progression of drugs like TNX-102 SL through clinical trials due to the potential market expansion and competitive advantage they can offer. Tonix Pharmaceuticals' collaboration with UNC and support from the DoD and NIH underscores the drug's perceived potential. The success of TNX-102 SL in trials could lead to an increase in Tonix's market share within the neuropsychiatric treatment space, particularly for trauma-related conditions.

Investors will be interested in the trial's progress, as positive results could lead to an increase in the company's stock value. The unique positioning of TNX-102 SL, targeting the immediate aftermath of trauma, sets it apart from other treatments that focus on chronic management. The trial's outcome will be a key driver of Tonix's credibility and could attract partnerships or acquisition interest from larger pharmaceutical companies seeking to expand their mental health portfolios.

Bedtime TNX-102 SL improves sleep quality in PTSD and is also being developed for the management of fibromyalgia for which NDA preparation is ongoing

Investigator-Initiated OASIS Trial at UNC is a Phase 2 180-patient, randomized, placebo-controlled trial in acute trauma patients following motor vehicle collisions

One-third of emergency department visits in the U.S. (40-50 million patients per year) involve evaluation after trauma exposures

CHATHAM, N.J., Feb. 12, 2024 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug (IND) application for the Phase 2 investigator-initiated OASIS trial to evaluate TNX-102 SL1 in reducing the severity of acute stress reaction (ASR) and the frequency of acute stress disorder (ASD) and posttraumatic stress disorder (PTSD). The trial is sponsored by The University of North Carolina (UNC) Institute for Trauma Recovery and supported by a $3 million grant from the U.S. Department of Defense (DoD).

“No medication is currently available at or near the point-of-care to treat patients suffering from traumatic events and support long-term health,” said Seth Lederman, M.D., Chief Executive Officer of Tonix. “There is an unmet need for treating ASR after traumatic events such as civilian motor vehicle collisions or warfighter experiences in forward bases or in theater. Previous trials of TNX-102 SL in PTSD suggested activity on sleep and stress related symptoms in the first several weeks of treatment.2,3 The study is motivated 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.”

The Optimizing Acute Stress Reaction Interventions with TNX-102 SL (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 will 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 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.

“This innovative clinical trial and partnership will help address the need for safe and effective therapies to treat acute trauma,” said Samuel McLean, M.D., Professor of Psychiatry and Emergency Medicine at the UNC School of Medicine at UNC, School of Medicine, and lead principal investigator of the proposed study. “ASR and posttraumatic stress symptoms are common among civilian motor vehicle collision survivors. The AURORA initiative, which has collected thousands of data points from motor vehicle collisions, has allowed us to better investigate the correlation between motor vehicle collisions and the emergence of acute stress disorder or PTSD symptoms. In OASIS, we will test a pharmacological intervention in the immediate aftermath of trauma that has potential for fast relief of stress symptoms, improvement in coping and functioning, and preclusion of escalation to more severe conditions, ASD in the short term and PTSD thereafter.”

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 emergency department 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
