Trial 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.
An Open Label, Multicenter, Dose Escalation and Expansion, Phase 1 Study to Evaluate Safety, Pharmacokinetics, and Preliminary Anti-Tumor Activity of RO7121661, a PD-1/TIM-3 Bispecific Antibody, in Patients With Advanced and/or Metastatic Solid Tumors
Eligibility Criteria
General Inclusion Criteria:

Additional Specific Inclusion Criteria for Participants with Melanoma:
- Histologically confirmed, unresectable stage III or stage IV melanoma
- Previously treated with approved anti-programmed death-ligand 1 (PD-L1)/anti-programmed death-1 (PD-1) agents with or without approved anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) therapy and up to one additional treatment regimen
