On 27 February 2025, the European Medicines Agency’s (EMA’s) Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion, recommending a change to the terms of the marketing authorisation for the medicinal product trastuzumab deruxtecan (Enhertu).
The marketing authorisation holder for this medicinal product is Daiichi Sankyo Europe GmbH.
The CHMP adopted an extension to an existing indication to include treatment of adults with unresectable or metastatic HR-positive HER2-low or -ultralow breast cancer.
The full indications for Enhertu will therefore be as follows (new indication in bold):
Breast cancer
- HER2-positive breast cancer
Enhertu as monotherapy is indicated for the treatment of adult patients with unresectable or metastatic HER2-positive breast cancer who have received one or more prior anti-HER2-based regimens.
- HER2-low and HER2-ultralow breast cancer
Enhertu as monotherapy is indicated for the treatment of adult patients with unresectable or metastatic
- hormone receptor (HR)-positive, HER2-low or HER2-ultralow breast cancer who have received at least one endocrine therapy in the metastatic setting and who are not considered suitable for endocrine therapy as the next line of treatment.
- HER2-low breast cancer who have received prior chemotherapy in the metastatic setting or developed disease recurrence during or within 6 months of completing adjuvant chemotherapy.
Non-small cell lung cancer (NSCLC)
Enhertu as monotherapy is indicated for the treatment of adult patients with advanced NSCLC whose tumours have an activating HER2 (ERBB2) mutation and who require systemic therapy following platinum-based chemotherapy with or without immunotherapy.
Gastric cancer
Enhertu as monotherapy is indicated for the treatment of adult patients with advanced HER2-positive gastric or gastro-oesophageal junction adenocarcinoma who have received a prior trastuzumab-based regimen.
Detailed recommendations for the use of this product will be described in the updated summary of product characteristics, which will be published on the EMA website in all official European Union languages after a decision on this change to the marketing authorisation has been granted by the European Commission.
Summaries of positive opinion are published without prejudice to the Commission decision, which will normally be issued 67 days from adoption of the opinion
