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 R-DXd, Bevacizumab, or Carboplatin. The registry lists allocation as randomized. Researchers are looking for new ways to treat advanced, high-grade ovarian cancer (OC).
They plan to enroll about 646 people at 7 sites. Taking part typically means taking a study drug (or dummy pill), an infusion or injection of a biologic plus check-ins.
