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 Serabelisib, Sapanisertib, or Fulvestrant. The registry lists allocation as randomized. The study is a Phase 1b/2, multi-center, open-label, dose escalation trial evaluating the safety and preliminary how well it works of sapanisertib and serabelisib (PIKTOR) with fulvestrant and/or other anticancer therapies in participants with HR+/HER2- advanced/metastatic breast cancer.
They plan to enroll about 32 people at 7 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
