You may not be if
2. Alpha-fetoprotein (AFP)-producing gastric cancer (GC): Histologically confirmed GC with AFP \> 20 ng/mL in blood or tumor tissue positive for AFP by a validated immunohistochemistry (IHC) assay based on local or central testing.
3. Germ cell tumors: Histologically confirmed germ cell tumors including extragonadal yolk sac tumors (e.g., located in the mediastinum, vagina, brain, retroperitoneum), and non-dysgerminomas for which no further curative systemic treatment options exist.
4. Glypican-3 (GPC3)-positive squamous non-small cell lung cancer (NSCLC): Histologically confirmed GPC3-positive squamous NSCLC with prior exposure to a checkpoint inhibitor (CPI).
2. At least one evaluable lesion for dose escalation, and at least one measurable lesion for safety expansion, as defined by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
3. Eastern Cooperative Oncology Group (ECOG) Performance Status ≤ 1.
4. Adequate organ function as defined in the protocol.
5. Provision of tumor tissue samples is required for specified parts of the study.
1. Prior therapy directed against glypican-3 (GPC3) or the T-cell costimulatory receptor 4-1BB (CD137).
2. Active leptomeningeal disease or uncontrolled/untreated brain metastases.
3. Active autoimmune disease or a history of autoimmune disease with potential for relapse.
4. Any malignancy diagnosed ≤ 2 years before the first dose of study drug(s), except: The cancer type under investigation in this study, or Locally recurring malignancies previously treated with curative intent.
5. Requirement for systemic corticosteroids (\> 10 mg/day prednisone or equivalent) or other immunosuppressive therapy within 14 days prior to the first dose of study drug(s).
6. Certain comorbidities involving the lungs, heart, bleeding conditions, or active infections, as defined in the protocol.
