Summary
Following positive preclinical data, Kazia is expanding its ongoing triple-negative breast cancer trial to include HR+/HER2- patients. The study will evaluate paxalisib combined with fulvestrant and palbociclib, targeting a critical gap in treatment for the most common breast cancer subtype.
