BEBT-209, a primary CDK4 selective inhibitor, for the treatment of HR+/HER2- advanced breast cancer (BECTOP1): a phase 1, multicentre, open-label study. (PubMed, Breast) - "BEBT-209 was a primary CDK4 selective inhibitor and showed an acceptable safety profile and dose-dependent plasma exposure. The results highlight the potential of combination treatments as compelling options, particularly in combination with fulvestrant."

Efficacy and safety of BEBT-209, a primary CDK4 inhibitor, in combination with gemcitabine and carboplatin for metastatic triple-negative breast cancer. (ASCO 2025) - P2 | "Antibody-drug conjugates (ADCs), such as sacituzumab govitecan (SG), demonstrate limited efficacy, achieving a 31% objective response rate (ORR) and mPFS of 4.8 months in the ASCENT trial. BEBT-209 in combination with GC demonstrates promising efficacy and a favorable safety profile in mTNBC patients with early relapse or prior systemic therapy. The observed improvements in ORR and PFS compared to current standards of care highlight the potential of BEBT-209 as a breakthrough therapy for this aggressive disease. A global Phase III trial is planned to further validate these findings."
