Dr. Rosenberg Will Lead Clinical Development of Tonix’s Vaccine and Antiviral Programs

CHATHAM, N.J., Jan. 04, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced the appointment of Zeil Rosenberg, M.D., M.P.H. as its new Executive Vice President, Medical. In this role, Dr. Rosenberg will be responsible for leading Tonix’s clinical development efforts for vaccines and antivirals. Dr. Rosenberg will be based in the Company’s Chatham, N.J. headquarters, and as part of his role will oversee the clinical development of Tonix’s vaccine for smallpox and monkeypox, TNX-801, the vaccine for COVID-19, TNX-1850, and the antiviral anti-SARS-CoV-2 spike protein monoclonal antibodies, TNX-3600 and TNX-3800, to protect immunocompromised individuals from severe COVID-19.

“We are pleased to welcome Dr. Rosenberg to Tonix’s clinical team to lead the development of our infectious disease programs at a time when Tonix continues to make meaningful progress in the clinical development of multiple programs within its robust pipeline,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals.

“Dr. Rosenberg brings to our team expertise as an infectious disease drug developer and we are fortunate to have someone with Dr. Rosenberg’s skills, vision and operational expertise join at a pivotal time in the evolution of our infectious disease product portfolio, with our vaccine candidate for monkeypox, TNX-801, expected to enter clinical testing in 2023, and TNX-3600 and TNX-3800 moving ahead in pre-clinical development to address the need for anti-SARS-CoV-2 monoclonal antibodies for immune-compromised individuals,” said Gregory Sullivan, M.D., Chief Medical Officer of Tonix Pharmaceuticals. “At Becton, Dickinson and Company (BD), Dr. Rosenberg worked on the development of the BD Bifurcated Needle, a safety-engineered improved bifurcated needle device for the percutaneous administration of live virus vaccinia vaccines, as well as BD VaxiNet™, a data monitoring system to improve patient safety in smallpox vaccine mass immunization efforts, which we believe have direct relevance to our recombinant poxvirus (RPV) platform.”

“I am thrilled to join Tonix’s executive management team and lead the clinical development of its infectious disease portfolio,” said Dr. Rosenberg. “I look forward to working together with the talented Tonix team to advance the Company’s portfolio of promising vaccines and antiviral therapies and help bring them to as many appropriate patients as possible.”

Dr. Rosenberg was most recently at PPD, part of Thermo Fisher Scientific, serving as Executive Director, Biotech and as Therapeutic Area Head for Vaccines at its Accelerated Enrollment Solutions Group, where he provided leadership on multiple successful COVID-19 vaccine clinical trials. At BD he was Worldwide Business Leader and Medical Director for Immunization, and was Vice President for Medical Affairs at Admera Health, a medical diagnostics company focused on precision medicine. He was key to the launch of a global public private partnership, including UNICEF and WHO, to help eliminate maternal and neonatal tetanus through immunization, resulting in the significant reduction of neonatal mortality. He served as National Immunization Advisor to the Indonesian Ministry of Health in Jakarta, sponsored by the U.S. Agency for International Development (USAID), and as Chief Technical Officer for Immunization at USAID, Washington, D.C.

Dr. Rosenberg received his B.A. with Honors and Distinction at Stanford University, earned his M.D. at the University of California, San Francisco and completed his internship and residency at Mount Sinai and Cornell University Medical College, respectively. He holds a Masters of Public Health from Columbia University. Dr. Rosenberg is an elected Fellow of both the American College of Preventive Medicine and the New York Academy of Medicine, and Specialty Fellow of the American Academy of Pediatrics.
