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 relugolix + ARPI, Intermittent- Relugolix or androgen deprivation therapy (ADT) + ARPI, or relugolix or androgen deprivation therapy (ADT) + ARPI. The registry lists allocation as randomized. This study wants to evaluate intermittent relugolix + androgen receptor pathway inhibitor (ARPI) in patients with metastatic hormone-sensitive prostate cancer (mHSPC) achieving optimal PSA response.
They plan to enroll about 160 people at Salt Lake City. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
