What this phase means
Phase 2: researchers already know a roughly safe dose (from phase 1). This stage asks whether the treatment actually helps the condition, and watches side effects more 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 Biospecimen Collection, Computed Tomography, or Cystoscopy. The registry lists allocation as na. This phase II trial tests the effect of giving pembrolizumab in combination with radiation therapy after chemotherapy in preventing surgery to remove the bladder in patients with muscle invasive bladder cancer.
They plan to enroll about 111 people at 182 sites. Taking part typically means an infusion or injection of a biologic, a procedure as part of the study plus check-ins.
