"Boundless remains committed to delivering new therapeutic options to patients with high unmet need oncogene amplified cancers," said Zachary Hornby, President and CEO of Boundless Bio. "We look forward to providing a clinical data update on our BBI-355 program later this year. Additionally, we expect to nominate a development candidate for our novel Kinesin program by mid-year, with plans to submit an IND in the first half of 2026."

Research and Development Highlights and Upcoming Milestones

BBI-355, a novel, oral, potent CHK1 inhibitor designed to target replication stress in oncogene-amplified cancers


Enrollment is ongoing in the Phase 1/2 POTENTIATE trial. Preliminary clinical proof-of-concept safety and antitumor activity data are expected in the second half of 2025.

Novel Kinesin program targeting ecDNA segregation and inheritance


Boundless expects to nominate a development candidate for its preclinical program targeting a previously undrugged kinesin by mid-2025, with an investigational new drug (IND) submission planned for the first half of 2026.

Recent Data Presentations


Preclinical data from studies conducted with Boundless’s ribonucleotide reductase (RNR) inhibitor, BBI-825, were presented in an oral session at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting. These data suggest that the combination of BBI-825 with mutant-specific, pan, and multi-RAS targeting inhibitors delayed or prevented acquired resistance in colorectal cancer preclinical models. Boundless continues to preclinically evaluate BBI-825 in various treatment settings.
