• Trastuzumab deruxtecan (T-DXd) shows promise across breast, gynecologic, gastrointestinal, lung, and genitourinary cancers, targeting HER2-positive, -mutated, and -amplified diseases.
• In gynecologic cancers, the DESTINY-PanTumor02 trial demonstrated significant response rates with T-DXd in endometrial, cervical, and ovarian cancers, particularly in HER2 IHC3+ patients.
• T-DXd has received FDA approval for HER2-mutant NSCLC and HER2-positive solid tumors, marking advancements in targeted therapies for previously hard-to-treat cancers.
• Clinical trials like DESTINY-Breast03 and DESTINY-Gastric01 support T-DXd's efficacy, showing improved PFS and OS compared to standard treatments in breast and gastric cancers.
