Brief Summary:
This is a first-in-human, open-label, multicenter, Phase I multiple-ascending dose (MAD) study of single agent lomvastomig (RO7121661), an anti PD-1 (programmed death-1) and TIM-3 (T-cell immunoglobulin and mucin domain 3) bispecific antibody, for participants with advanced and/or metastatic solid tumors. The study consists of 2 parts: Dose Escalation (Part A) and Expansion (Parts B1, B2, B3, B4, and B5). The Dose Escalation part will be conducted first to determine the maximum tolerated dose (MTD) and/or recommended dose for expansion (RDE) based on safety, tolerability, pharmacokinetic, and/or the pharmacodynamic profile of escalating doses of lomvastomig. The Expansion part will enroll tumor-specific cohorts to evaluate anti-tumor activity of the MTD and/or RDE of lomvastomig from Part A (Q2W) and to confirm safety and tolerability in participants with selected tumor types.
