Registration Number
NCT05536141
Lead Sponsor

Brief Summary

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

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

Key

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.
