Tizona Initiates Clinical Development of TTX-080 in Advanced Cancers
-IND Cleared by US FDA with Study Enrollment to Begin in Q3 2020
-First Anti-HLA-G Antibody into the Clinic
SOUTH SAN FRANCISCO, Calif., June 25, 2020 — Tizona Therapeutics, Inc., a privately held, clinical stage company developing first-in-class cancer immunotherapies, announced today that its Investigational New Drug (IND) application for TTX-080, a novel antibody targeting HLA-G, has been cleared by the U.S. Food and Drug Administration (FDA). The first clinical study of TTX-080 will be initiated in advanced cancers in Q3 2020.
TTX-080, discovered at Tizona, is the first anti-HLA-G antibody to enter clinical development. HLA-G is normally expressed at the maternal-fetal interface and certain other sites of immune privilege. In cancer, its expression is used as an immune evasion strategy. By blocking the interaction of HLA-G with its receptors, TTX-080 prevents the suppression of both innate and adaptive immune activity and has the potential to enhance anti-tumor responses. Tizona plans to evaluate TTX-080 as both a monotherapy and in combination therapy in advanced cancers in a Phase 1 clinical trial.
“We are excited to begin clinical development of TTX-080, our second investigational first-in-class cancer immunotherapy,” said Scott Clarke, Chief Executive Officer, Tizona. “This represents an important expansion of our efforts to develop truly novel therapeutics and takes us a step forward on our mission to bring transformational medicines to people with cancer.”
