Seth Lederman, MD is a physician,[1] scientist and specialty pharmaceuticals entrepreneur. He is a co-founder and the current President and Chairman[2][3] of Tonix Pharmaceuticals,[4] a specialty pharmaceutical product development and commercialization company.

Biography

Lederman earned his Bachelor's degree in Chemistry from Princeton University where he graduated cum laude in 1979.[5] He completed his M.D. from Columbia University in 1983[6] and continued his training at the Columbia Presbyterian Medical Center until 1986. Lederman became instructor at Columbia in 1985, Assistant Professor in 1988 and Associate Professor with tenure in 1996. In 2015 he took a leave from Columbia.

As Assistant Professor at Columbia, Dr. Lederman discovered the CD40-Ligand (CD154) and elucidated the molecular basis of T cell helper function. Dr. Lederman’s work on the CD40-Ligand (CD154) led to the development of therapeutic candidates for autoimmune diseases and organ transplant rejection in collaboration with Biogen and UCB/CellTech.[2] He also collaborated with Professor David Baltimore in identifying and functionally characterizing the CD40 signaling molecule, TRAF-3.[7] Dr. Lederman’s “early work on HIV contributed to the understanding of how the V3 loop of HIV gp120 was involved in fusion with CD4 cell membranes, an early and essential event in viral entry and infection”.[8]

Lederman founded Targent Pharmaceuticals, which sold levoleucovorin to Spectrum Pharmaceuticals, who market it as Fusilev. Fusilev is approved for the treatment of advanced colorectal cancer and for methotrexate rescue. Lederman co-founded and served as a managing partner of Konanda Pharma Partners and Konanda Pharma Fund I, LP, and its wholly owned operating companies, Validus and Fontus Pharmaceuticals Inc. Validus acquired Fontus and markets Equetro (carbamazepine – Extended Release), Marplan (isocarboxazid) and Rocaltrol (calcitriol).[2]

Tonix Pharmaceuticals

As of April 2016, Tonix had approximately twenty-five employees. Lederman is a co-founder and current CEO;.[4] Bradley Saenger, CPA and Bruce Daugherty, PhD hold positions of CFO and CSO, respectively.[3] Founded in 2007 and based in New York City,[3] the company specializes in developing next generation medicines for central nervous system disorders. Among the current projects of the company is the development of TNX-102 SL (cyclobenzaprine HCl, 2.8 mg tablets for sublingual administration) for the management of fibromyalgia and for the treatment of post-traumatic stress disorder. TNX-102 SL is currently being tested in a Phase 3 study (the AFFIRM Trial) for fibromyalgia and in a Phase 2 study (the AtEase Trial) for PTSD. In addition, TNX-301 (disulfiram 250 mg/selegiline 4 mg tablets), is in preclinical development. The company was listed on the NASDAQ exchange in 2013 under the symbol TNXP.[4][9] In addition to corporate headquarters in New York City, the company has facilities in La Jolla, CA; San Jose, CA; Montreal, Quebec, Canada and Dublin, Ireland.
