Zongertinib, sold under the brand name Hernexeos, is an anti-cancer medication used for the treatment of non-small cell lung cancer.[1][2] Zongertinib is a kinase inhibitor of human epidermal growth factor receptor 2 (HER2).[1][3][4] It is taken by mouth.[1]

Zongertinib was approved for medical use in the United States in August 2025.[5]

Medical uses

Zongertinib is indicated for the treatment of adults with unresectable or metastatic non-squamous non-small cell lung cancer whose tumors have HER2 (ERBB2) tyrosine kinase domain activating mutations, as detected by an FDA-approved test, and who have received prior systemic therapy.[1][5]

Adverse effects

The US Food and Drug Administration prescribing information includes warnings and precautions for hepatotoxicity, left ventricular dysfunction, interstitial lung disease/pneumonitis, and embryo-fetal toxicity.[1][5]

History

Efficacy was evaluated in participants with unresectable or metastatic, non-squamous non-small cell lung cancer with HER2 (ERBB2) TKD mutations who had received prior systemic therapy and received zongertinib in Beamion LUNG-1 (NCT04886804), an open-label, multi-center, multi-cohort trial.[5] The major efficacy outcome measures were objective response rate (ORR) and duration of response (DOR) determined by blinded independent central review per RECIST v1.1.[5]

The US Food and Drug Administration granted the application for zongertinib priority review, breakthrough therapy, and fast track designations.[5]

Society and culture

Zongertinib was approved for medical use in the United States in August 2025.[2][6]
