A Phase 1 Study of AB521 Monotherapy and Combination Therapies in Renal Cell Carcinoma and Other Solid Tumors
Purpose
The purpose of this study is to evaluate the safety and tolerability of: - casdatifan when taken alone in participants with advanced solid tumor malignancies and clear cell renal cell carcinoma (ccRCC) during the dose escalation stage; and - casdatifan monotherapy and casdatifan in combination with cabozantinib or zimberelimab in participants with ccRCC in the dose expansion stage
Conditions
- Clear Cell Renal Cell Carcinoma
- Solid Tumors
Eligibility
- Eligible Ages
- Over 18 Years
- Eligible Genders
- All
- Accepts Healthy Volunteers
- No
Inclusion Criteria
- Must have at least one measurable lesion per RECIST guidance - Eastern Cooperative Oncology Group (ECOG) performance status score of ≤ 1 - Disease-specific criteria for dose escalation: - Participants may have any pathologically confirmed solid tumor type where no other treatment options are available - Creatinine clearance ≥ 40 mL/min Disease-specific criteria for dose-expansion: - Histologically confirmed ccRCC - Creatinine clearance ≥ 40 mL/min
Exclusion Criteria
- Use of any live vaccines against infectious diseases (eg, influenza, varicella) within 4 weeks (28 days) of initiation of investigational product - Has any other clinically significant cardiac, respiratory, or other medical or psychiatric condition that might interfere with a participant's participation in the clinical study or make the administration of investigational product hazardous - History of trauma or major surgery within 28 days prior to the first dose of investigational product - For all expansion cohorts: prior treatment with an hypoxia inducible factor (HIF)-2α inhibitor. For the casdatifan + cabozantinib combination cohort, any prior treatment with cabozantinib - Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial Note: Other protocol defined Inclusion/Exclusion criteria may apply.
