Overview
The purpose of this study is to find out if ZW251, an antibody-drug conjugate targeting glypican-3 (GPC3), is safe and can treat participants with advanced cancers, including hepatocellular carcinoma (HCC), squamous cell non-small cell lung cancer (NSCLC), or germ cell tumors (GCT).
Description
Part 1 (dose escalation) of the study will evaluate the safety and tolerability of ZW251 in HCC, squamous cell NSCLC, and GCT. Part 2 (dose optimization) of the study will further assess safety and potential anti-tumor activity of the ZW251 established recommended doses in HCC.
Eligibility
Inclusion Criteria:
- Pathologically or cytologically confirmed diagnosis of HCC with evidence of locally advanced (unresectable, and ineligible for transplant) and/or metastatic disease. Noninvasive methods may be used to confirm diagnosis
- Pathologically or cytologically confirmed diagnosis of squamous cell NSCLC with evidence of locally advanced (unresectable) and/or metastatic disease
- Pathologically or cytologically confirmed diagnosis of GCT with evidence of yolk sac and/or choriocarcinoma predominant component and locally advanced (unresectable) and/or metastatic disease
- Measurable disease per RECIST v1.1
- Eastern Cooperative Oncology Group (ECOG) Performance Status score of 0 or 1
- Liver function status of Child-Pugh Class A (for HCC only)
- Adequate organ function
Exclusion Criteria:
- Known additional malignancy that is progressing or that has required active treatment within the last year
- History of hepatic encephalopathy within the past 6 months or requirement for medications to control encephalopathy
- Participants with HCC experiencing main portal vein tumor invasion require sponsor approval for enrollment
- Known gastrointestinal bleeding within 3 months
- Acute or chronic uncontrolled renal disease, pancreatitis, or non-malignant liver disease
