23ANDME HOLDING CO. 23andMe Holding Co. announced that two abstracts on 23ME-00610, a first-in-class anti-CD200R1 antibody, have been accepted for poster presentations at the 2024 ASCO Annual Meeting, taking place May 31 - June 4 in Chicago. 23andMe will present clinical data, including preliminary efficacy and exploratory biomarker analyses, for the neuroendocrine and ovarian cancer patient cohorts in the Phase 2a portion of its ongoing Phase 1/2a clinical trial.
23andMe scientists discovered the target for 23ME-00610 through the company?s proprietary database of human genetic and health information. 23andMe has more than 15 million genotyped customers, roughly 80% of whom consent to participate in research. By analyzing de-identified, aggregate genetic and health data from consented research participants, 23andMe identified genetic variants of CD200R1, CD200, and DOK2, the downstream signaling protein, associated with higher risks of immune disease and lower risks of cancer, pinpointing CD200R1 as a promising immuno-oncology target.
Additional preclinical data validated the CD200-CD200R1 pathway as an immune checkpoint, and potential target for reversing immune tolerance in cancer as a monotherapy, or in combination with other therapies. Clinical data from the dose escalation cohort of patients with advanced solid tumors has shown 23ME-00610 has favorable pharmacokinetics (PK) for dosing once every three weeks, expected on-target pharmacologic activity, and a promising safety and tolerability profile at the preliminary recommended phase 2 dose of 1400 mg.
