A Dose Escalation and Expansion Study of Lomvastomig, a PD-1/TIM-3 Bispecific Antibody, in Participants With Advanced and/or Metastatic Solid Tumors
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.

Who may be able to participate
The sponsor separates these requirements into two groups. You do not need to interpret them alone—use them to guide a conversation with the study team.
- General Inclusion Criteria:
- Part A: Patient must have histologically or cytologically confirmed advanced and/or metastatic solid tumor malignancies for which standard curative or palliative measures do not exist, are no longer effective, or are not acceptable to the patient
- Eastern Cooperative Oncology Group Performance Status 0-1
- Measurable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST v1.1)
- Fresh biopsies may be required
- Negative HIV, hepatitis B, or hepatitis C test result
- Women of childbearing potential and male participants must agree to remain abstinent or use contraceptive methods as defined by the protocol 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 Additional Specific Inclusion Criteria for Participants with Non-small Cell Lung Cancer (NSCLC) who Previously Received Treatment for Metastatic Disease:
- Histologically confirmed advanced NSCLC
- Previously treated with approved PD-L1/PD-1 inhibitors and platinum-based chemotherapy
- Not more than 2 prior lines of treatment for metastatic disease are allowed prior to enrolling to the study
- Participants must have experienced initial clinical benefit (stable disease or better) from most recent checkpoint inhibitor (CPI) therapy

- Histologically confirmed advanced NSCLC
- Tumor PD-L1 expression as determined by immunohistochemistry assay of archival tumor tissue or tissue obtained at screening Additional Specific Inclusion Criteria for Participants with Small Cell Lung Cancer (SCLC):
- Histologically confirmed SCLC
- Participants may have had prior chemotherapy, radiation therapy, or declined approved therapies for SCLC Additional Specific Inclusion Criteria for Participants with Esophageal Squamous Cell Carcinoma (ESCC):
- Participants whose major lesion was histologically confirmed as squamous cell carcinoma or adenosquamous cell carcinoma of the esophagus
- Patients who have previously received not more than 1 prior line of treatment for metastatic disease prior to enrolling to the study
