New hope for hard-to-treat breast cancer: combo therapy enters human trials
NCT ID NCT07336771
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new two-drug combination (JSKN016 plus D-0502) in 60 people with advanced hormone receptor-positive, HER2-negative breast cancer whose disease worsened after standard hormone therapy. The goal is to see if the combination is safe and shrinks tumors. Participants receive the drugs either every 2 or 3 weeks by IV plus a daily pill.
