About ABCL635

ABCL635 is a potential first-in-class antibody drug for the non-hormonal treatment of moderate-to-severe VMS, commonly known as hot flashes, due to menopause. ABCL635 specifically targets NK3R, a clinically validated G protein-coupled receptor (GPCR) expressed on KNDy neurons in the infundibular nucleus of the hypothalamus. ABCL635 is the first program from AbCellera’s GPCR and ion channel platform to advance into the pipeline, entering the clinic in July 2025. Additional details are available at www.abcellera.com/pipeline.

The Phase 2 trial of ABCL635 (NCT07118891) is a multicenter, randomized, double-blind, placebo-controlled trial with approximately 80 postmenopausal women designed to evaluate the efficacy of ABCL635 in reducing the frequency and severity of moderate-to-severe VMS.
