Latest Developments in Global HER2 Tyrosine Kinase Inhibitor Drugs Market

• In March 2025, the U.S. Food and Drug Administration (FDA) granted orphan drug designation to Nerlynx (neratinib) for the treatment of HER2‑positive breast cancer patients with brain metastases, highlighting expanded clinical focus on unmet needs in advanced disease settings. Neratinib is already approved for extended adjuvant therapy in early HER2‑positive breast cancer and is being evaluated in combination therapies to further improve outcomes in patients with metastatic disease, reflecting its evolving clinical role in targeted HER2 inhibition
• In August 2025, the FDA granted accelerated approval to zongertinib (marketed as Hernexeos), the first orally administered HER2‑selective tyrosine kinase inhibitor for adults with unresectable or metastatic non‑squamous non‑small cell lung cancer (NSCLC) harboring HER2 TKD activating mutations. This approval, based on data from the Beamion LUNG‑1 trial demonstrating strong objective response rates and durable responses, marks a significant expansion of HER2 TKI use beyond breast cancer into difficult‑to‑treat lung cancer subtypes
• In October 2025, Pfizer announced positive topline results from the Phase 3 HER2CLIMB‑05 trial of TUKYSA (tucatinib) as part of first‑line maintenance therapy in HER2‑positive metastatic breast cancer, showing a statistically significant improvement in progression‑free survival when added to standard maintenance regimens. These results underscore the continued clinical refinement of HER2 TKI therapies and their integration into earlier lines of treatment to extend disease control for patients
