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 TAR-210, Mitomycin C, or Gemcitabine. The registry lists allocation as randomized. The main purpose of this study is to compare the disease-free survival (the length of time after randomization that a participant survives without any signs or symptoms of the cancer returning, or progressing) between Bacillus Calmette-Guérin (BCG) treated participants receiving treatment with TAR-210 versus investigator's choice of intravesical chemotherapy for treatment of high-risk non-muscle-invasive bladder cancer (HR-NMIBC).
They plan to enroll about 220 people at 115 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.

Interventions: TAR-210, Mitomycin C, Gemcitabine
