Tonix Pharmaceuticals Launches Pivotal MDD Study for TNX-102 SL
- Study Initiation: On June 29, 2026, Tonix Pharmaceuticals announced the enrollment of the first patient in the HORIZON study, evaluating TNX-102 SL (5.6 mg) as a first-line monotherapy for major depressive disorder (MDD), with approximately 360 patients expected to be recruited across 30 sites in the U.S., demonstrating the company's commitment to expanding its presence in mental health.
- Clinical Objectives: The primary endpoint of the study is the change from baseline in the MADRS total score at Week 6, aimed at validating the efficacy of TNX-102 SL in improving depressive symptoms and sleep quality, reflecting Tonix's focus on new therapies amid challenges with tolerability and adherence in existing treatments.
- Market Demand: With over 21 million adults in the U.S. experiencing a major depressive episode each year, there is an urgent need for new effective treatments; the development of TNX-102 SL not only addresses this market gap but also has the potential to improve patient quality of life and reduce suicide risk.
- Drug Characteristics: TNX-102 SL is a novel sublingual tablet formulation that enables rapid absorption and reduces the production of active metabolites, featuring a multifaceted mechanism of action targeting neuronal receptors that influence sleep quality, indicating promising applications in MDD and other related conditions.

Raymond James Initiates Strong Buy Ratings for Tonix and MapLight
- Strong Buy Ratings: Raymond James has initiated coverage on Tonix Pharmaceuticals (TNXP) and MapLight Therapeutics (MPLT), assigning price targets of $26 and $46 per share respectively, with expectations that upcoming catalysts will drive stock price increases.

- Commercial Update Anticipation: Fauth expects Tonix to release its first commercial update on Tonmya in Q2 2026, which is the first FDA-approved fibromyalgia therapy in over 15 years, projecting peak sales of $400M to $500M, thereby providing a supportive floor for TNXP shares.
- MapLight Catalyst: MapLight's ML-007C-MA, targeting schizophrenia and Alzheimer's disease psychosis, is expected to have its mid-stage trial results released in mid-August, with the analyst suggesting that this readout is skewed to the upside and could emerge as a significant value driver for the company.
