Remarks

December 17, 2019 The FDA granted accelerated approval to fam-trastuzumab deruxtecan-nxki for patients with unresectable or metastatic HER2-positive breast cancer who have received two or more prior anti-HER2-based regimens in the metastatic setting.

January 15, 2021 FDA has approved Enhertu (fam-trastuzumab deruxtecan-nxki) for adult patients with locally advanced or metastatic HER2-positive gastric or gastroesophageal adenocarcinoma who have received a prior trastuzumab-based regimen.

September 9, 2022 FDA approved Enhertu (fam-trastuzumab-deruxtecan-nxki) for unresectable or metastatic HER2-low breast cancer. Enhertu is a specifically engineered HER2-directed antibody drug conjugate.

September 9, 2022 FDA granted accelerated approval to Enhertu (fam-trastuzumab deruxtecan-nxki) for adult patients with unresectable or metastatic NSCLC whose tumors have activating HER2 mutations, as detected by an FDA-approved test, and who have received a prior systemic therapy.

April 5, 2024 FDA granted accelerated approval to fam-trastuzumab deruxtecan-nxki (Enhertu) for adult patients with unresectable or metastatic HER2-positive (IHC3+) solid tumors who have received prior systemic treatment and have no satisfactory alternative treatment options.

January 31, 2025 FDA approved trastuzumab deruxtecan for the treatment of adult patients with unresectable or metastatic hormone receptor-positive, HER2-low (IHC 1+ or IHC 2+/ISH-) or HER2-ultralow (IHC 0 with membrane staining) breast cancer, as determined by the FDA approved test, that has progressed on one or more endocrine therapies in the metastatic setting.

On May 15, 2026, the Food and Drug Administration (FDA) approved fam-trastuzumab deruxtecan-nxki (T-DXd, Enhertu,) for two separate indications in adults with HER2-positive early-stage breast cancer. The first indication is for T-DXd followed by a taxane, trastuzumab, and pertuzumab (THP), for the neoadjuvant treatment of adult patients with HER2-positive (IHC 3+ or ISH+) Stage II or III breast cancer, as determined by an FDA-authorized test. The second indication is for T-DXd for the adjuvant treatment of adult patients with HER2-positive (IHC 3+ or ISH+) breast cancer who have residual invasive disease following neoadjuvant treatment with trastuzumab (with or without pertuzumab) and taxane-based treatment.
