This study evaluates the safety and effect of a drug called LOXO-783 (alone or combined with other medicines such as Fulvestrant or Abemaciclib) in patients with advanced breast cancer or other solid tumors. It enrolls adult patients whose tumor carries a PIK3CA H1047R mutation. The study is in Phase 1; it is currently active but not recruiting participants.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
