Boundless has identified a novel kinesin target ("Kinesin") essential to ecDNA segregation and inheritance in cancer cells, but non-essential in healthy cells. Boundless is developing BBI-940, a potentially first-in-class, oral, selective, Kinesin degrader, which is the subject of the ongoing first-in-human KOMODO-1 (Kinesin Oral Molecular Degrader for Oncology) clinical trial (NCT07408089) in patients with advanced or metastatic estrogen receptor-positive, HER2-negative (ER+/HER2-) breast cancer or triple-negative breast cancer of the luminal androgen receptor subtype (TNBC-LAR).
Details of the presentation are as follows:
Title: Selective degradation of a novel kinesin as a potential therapeutic strategy addressing high-risk extrachromosomal DNA (ecDNA) positive cancers, including breast cancer
Abstract Presentation Number: LB361
Session Title: Late-Breaking Research: Experimental and Molecular Therapeutics 3
Session Date and Time: Tuesday, April 21, 2026, 2:00 PM – 5:00 PM PT
Location: Poster Section 53
