About Us

Tonix is a biopharmaceutical company focused on bringing novel therapeutics and diagnostics to prevent and treat central nervous system disorders, immunology conditions, infectious diseases, and rare diseases.

At Tonix, we are focused on identifying and developing candidates that have the promise to treat and prevent human disease and alleviate suffering. Through our own development, in-licensing, collaborations and acquisitions we are curating an innovative and effective portfolio that targets the relief of pain and attenuates infection. Currently, our pipeline is primarily comprised 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. Our infectious disease portfolio includes a live virus vaccine platform, and a potential treatment for Long COVID. We are progressing small molecules and biologics to treat pain, neurologic, psychiatric and addiction conditions through our CNS portfolio.

Central Nervous System

Tonix’s lead CNS candidate, TNX-102 SL1 (sublingual formulation of cyclobenzaprine) is in mid-Phase 3 development for the management of fibromyalgia, a disorder characterized by chronic musculoskeletal pain, sleep deprivation, fatigue and mood changes. Tonix reported positive results from a Phase 3 study of TNX-102 SL in fibromyalgia in December 2020. TNX-102 SL is also being developed for Long COVID.


Tonix’s immunology portfolio includes TNX-1500, an anti-CD40L humanized monoclonal antibody, in development for organ transplant rejection as well as other autoimmune conditions. On the immuno-oncology front, TNX-1700 is in development for gastric and colorectal cancers.

Infectious Disease

Tonix’s lead infectious disease product candidate, TNX-8012, is a live horsepox virus vaccine for percutaneous administration  in development to protect against smallpox and monkeypox. Tonix will continue work on this live virus vector technology as a platform for rapid response to new pathogens.


Rare Disease

TNX-2900, Tonix’s proprietary potentiated intranasal oxytocin, is in development for the treatment of Prader-Willi syndrome (PWS), the most common genetic cause of life-threatening childhood obesity. TNX-2900 has been granted Orphan Drug Designation (ODD) in the US by the FDA for the treatment of PWS.
