Boundless Bio Announces Clinical Trial Collaboration & Supply Agreement with Taiho Oncology to Evaluate LYTGOBI + BBI-355 in Patients with FGFR Amplified Solid Tumors

This clinical trial collaboration and supply agreement with Taiho marks an important step in the continued execution of our clinical strategy and the next step in realizing the transformative potential of BBI-355, which we believe is the first ecDNA-directed therapy in development for patients with cancer that harbor oncogene amplifications on ecDNA,” said Zachary Hornby, President and Chief Executive Officer of Boundless Bio. “FGFR inhibitors given as monotherapy have to date demonstrated less clinical benefit in patients with cancer harboring FGFR amplifications than in patients with other FGFR driver alteration types. We believe that BBI-355, when combined with Taiho’s futibatinib, has the potential to demonstrate meaningful anti-tumor activity for patients with cancer and FGFR amplifications. We look forward to assessing this novel combination in our ongoing Phase 1/2 POTENTIATE trial.”
