FORE Biotherapeutics to Present Two Plixorafenib Abstracts at the American Association for Cancer Research Annual Meeting 2025

PHILADELPHIA--(BUSINESS WIRE)--FORE Biotherapeutics, a registration stage biotherapeutics company dedicated to developing targeted therapies to treat patients with cancer, today announced two plixorafenib abstracts have been selected for poster presentation at the American Association for Cancer Research (AACR) Annual Meeting 2025, taking place April 25-30 in Chicago.

The first poster features important results showing that circulating tumor DNA (ctDNA) accurately detects BRAF mutations from tumor biopsies and may be a surrogate marker for monitoring disease. The ctDNA results are from plixorafenib-treated patients and were an exploratory endpoint from a previously completed Phase 1/2a study. The second poster highlights the study design for the recently commenced Phase 2 FORTE basket study evaluating plixorafenib in patients with various types of BRAF-mutated tumors.

“Plixorafenib’s unique paradox breaking mechanism of action in tumors with BRAF alterations underscores its potential to redefine the standard of care for a patient population that has long been underserved and underpenetrated due to the limitations of current agents,” said William Hinshaw, Chief Executive Officer of Fore. “We are excited to share these compelling data with the medical community at AACR this year. We believe these results continue to support plixorafenib’s favorable product profile as a differentiated molecule and a potential best in class agent in the treatment of BRAF-driven tumors.”
