Bicara Therapeutics to Present Preclinical Data from Clinical-Stage Bifunctional Antibody Program, BCA101, at AACR Annual Meeting 2023

Bicara Therapeutics, a clinical-stage biotechnology company developing dual-action biologics to elicit a potent and durable immune response, today announced that it will present preclinical data supporting the ongoing clinical development of the lead investigational candidate BCA101, a bifunctional antibody designed to sequester the immunosuppressive TGF-? in the tumor microenvironment (TME) of EGFR+ tumors, at the upcoming American Association for Cancer Research (AACR) Annual Meeting 2023, being held April 14-19, 2023 in Orlando, Florida.

"The preclinical data that will be presented at AACR supports the mechanism of action (MOA) of BCA101, which has demonstrated promising efficacy and a positive safety profile in an ongoing Phase 1/1b clinical trial. Data from in vitro and in vivo studies provides further evidence of BCA101's potential, as a monotherapy and in combination with anti-PD-1, to induce durable anti-tumor responses in various tumor types, including head and neck cancer, our lead indication," said Rachel Salazar, SVP of R&D Strategy and Operations of Bicara Therapeutics. "We are also pleased to highlight our collaboration with researchers at the Belfer Center for Applied Cancer Science at Dana-Farber Cancer Institute to elucidate the effects of BCA101 on the tumor microenvironment of patients enrolled in the ongoing Ph1/1b clinical trial and highlight the important role of TGF-? neutralization in creating the conditions for an enhanced immune response."
