What this phase means
Phase 1: the first tests in people. The main question is safety and dose, not whether it cures the condition. Groups are small. Side effects are watched closely.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are casdatifan, Cabozantinib, or Zimberelimab. The registry lists allocation as randomized. This study wants to measure the whether it is safe and how hard side effects are to live with 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 this drug alone and casdatifan in combination with cabozantinib or zimberelimab or zimberelimab and ipilimumab in participants with ccRCC in the dose expansion stage.
They plan to enroll about 362 people at 21 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
