Immunome, Inc. (Nasdaq: IMNM), a biotechnology company focused on developing first-in-class and best-in-class targeted cancer therapies, today announced that the first patient has been dosed in the Phase 1, first-in-human trial of IM-1021, a ROR1-targeted ADC.

“Immunome is developing differentiated ADCs that we believe can greatly benefit cancer patients,” said Bob Lechleider, M.D., Chief Medical Officer at Immunome. “The dosing of our first patient with IM-1021 advances that mission, as we work to establish safety and explore efficacy of IM-1021 in patients with high unmet need in B-cell lymphomas and solid tumors.”

IM-1021 is an optimized, ROR1-targeted ADC that incorporates Immunome’s proprietary TOP1 inhibitor, HC74. The Phase 1 trial is an open-label, multicenter dose escalation and expansion study designed to determine the safety, tolerability, pharmacokinetics, and preliminary anti-tumor activity of IM-1021. The study is expected to include participants with advanced B-cell lymphomas and advanced solid tumors.
