New version of ovarian cancer drug tested for safety and effectiveness
NCT ID NCT07371104
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a new version of the drug olaparib (DWZ2501) works as well as the current version (DWC202510) in women with advanced BRCA-mutated ovarian cancer. About 40 participants will take both versions at different times to compare drug levels and safety. The goal is to confirm the new version is a suitable replacement for ongoing treatment.
