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 elacestrant, palbociclib, abemaciclib, ribociclib. The registry lists allocation as randomized. Breast cancer is not only the leading cause of cancer in women, but also the leading cause of cancer deaths in women.
They plan to enroll about 174 people at 3 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
