A Phase 1 Study of IM-1021 in Participants With Advanced Cancer

IM-1021-101 is a 2-part Phase 1 first-in-human (FIH), open-label, multicenter dose escalation and expansion study designed to determine the safety, tolerability, pharmacokinetics (PK), and preliminary anti-tumor activity of the ROR1 directed antibody-drug conjugate (ADC) IM-1021. IM-1021 will be administered to participants with advanced B-cell lymphomas and advanced solid tumors. Part A of the study is a dose escalation phase to evaluate safety and tolerability of IM-1021 and to determine recommended doses for further development. IM-1021 will be administered intravenously on an intermittent basis. The safety and tolerability of escalating doses of IM-1021 will be evaluated. Alternative dosing schedules may also be evaluated. Part B of the study is an expansion phase to further evaluate safety and tolerability of IM-1021 at candidate recommended doses in indication specific cohorts of participants. The safety and preliminary efficacy endpoints of this study will inform a preliminary risk-benefit assessment of IM-1021 in this patient population.
