What this phase means
Phase 3: this treatment already looked useful in smaller studies. Now it is tested in a large group, often against standard care or a dummy treatment, to see if it should be approved.
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 Placebo. The registry lists allocation as randomized. The purpose of the study is to measure the progression-free survival (PFS) of casdatifan versus dummy treatment (placebo) when each is given in combination with cabozantinib for patients who received anti-PD-1 or anti-PD-L1 therapy as part of the most recent regimen (either adjuvant this drug alone or first-line in combination with anti-CTLA-4 or VEGFR-TKI), with no more than 1 prior regimen in the metastatic setting.
They plan to enroll about 720 people at 188 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
