Friday, April 14, 2023

Tonix is a clinical-stage biopharmaceutical company focused on discovering, licensing, acquiring and developing therapeutics and diagnostics to treat and prevent human disease and alleviate suffering. Tonix’s portfolio is composed of immunology, rare disease, infectious disease, and central nervous system (CNS) product candidates. Tonix’s immunology portfolio includes biologics to address organ transplant rejection, autoimmunity and cancer, including TNX-15001 which is a humanized monoclonal antibody targeting CD40-ligand being developed for the prevention of allograft and xenograft rejection and for the treatment of autoimmune diseases. A Phase 1 study of TNX-1500 is expected to be initiated in the second half of 2022. Tonix’s rare disease portfolio includes TNX-29002 for the treatment of Prader-Willi syndrome. TNX-2900 has been granted Orphan-Drug Designation by the FDA. Tonix’s infectious disease pipeline includes a vaccine in development to prevent smallpox and monkeypox called TNX-8013, next-generation vaccines to prevent COVID-19, and an antiviral to treat COVID-19. Tonix’s lead vaccine candidates for COVID-19 are TNX-1840 and TNX-18504, which are live virus vaccines based on Tonix’s recombinant pox vaccine (RPV) platform. TNX-35005 (sangivamycin, i.v. solution) is a small molecule antiviral drug to treat acute COVID-19 and is in the pre-IND stage of development. TNX-102 SL6, (cyclobenzaprine HCl sublingual tablets), is a small molecule drug being developed to treat Long COVID, a chronic post-acute COVID-19 condition. Tonix expects to initiate a Phase 2 study in Long COVID in the second quarter of 2022. The Company’s CNS portfolio includes both small molecules and biologics to treat pain, neurologic, psychiatric and addiction conditions. Tonix’s lead CNS candidate, TNX-102 SL, is in mid-Phase 3 development for the management of fibromyalgia with a new Phase 3 study launched in the second quarter of 2022. Finally, TNX-13007 is a biologic designed to treat cocaine intoxication that is expected to start a Phase 2 trial in the second quarter of 2022. TNX-1300 has been granted Breakthrough Therapy Designation by the FDA.

Interim Analysis Cancelled For Two Trials. Tonix announced that it has eliminated the interim analyses for the Phase 3 RESILIENT trial testing TNX-102 SL in fibromyalgia and the Phase 2 PREVENTION trial testing TNX-601 in chronic migraine. Both trials were due to report interim analyses in 2Q23, and both trials will continue treatment with top-line results expected in 4Q23 as planned.  These interim results were not important drivers for the stock, and we expect little to no impact from their elimination.

Elimination Of The Interim Analysis Eliminates The Statistical Penalty. Clinical trials that include interim analysis have a “statistical penalty” for analyzing data before the conclusion of the trial. This often requires the final analysis to reach higher levels of statistical significance or show benefits of the drug in larger patient populations. By eliminating the interim analysis in its trials, Tonix can reduce the target enrollment for the PREVENTION trial from 300 to about 150 patients. This reduces the cost and time for the trial.
