Trastzumab Deruxtecan Versus SOC in Recurrent Ovarian That Progressed on Prior PARP Inhibitor Therapy
Ovarian, fallopian tube, and peritoneal cancers are often diagnosed at an advanced stage, requiring chemotherapy. Recently, the standard treatment, platinum-based chemotherapy plus PARP inhibitors, has extended disease-free survival (PFS). However, most patients eventually develop resistance to PARP inhibitors and become unresponsive to conventional treatments.
