Latest Developments in Global Oral HER Pathway Targeted Drugs Market

• In January 2025, the U.S. Food and Drug Administration (FDA) approved datopotamab deruxtecan (Datroway) for medical use in the United States and later in the European Union, expanding its indications to include locally advanced or metastatic non-small cell lung cancer (NSCLC) with prior EGFR-directed therapy and platinum-based chemotherapy. This approval highlighted the growing role of antibody-drug conjugates that target HER pathway-related mechanisms in oncology and underscored increasing regulatory support for oral and targeted treatment options in diverse tumor types
• In August 2025, the FDA granted accelerated approval to zongertinib (Hernexeos), an oral HER2-selective tyrosine kinase inhibitor developed by Boehringer Ingelheim, for adults with unresectable or metastatic non-squamous NSCLC harboring HER2 tyrosine kinase domain mutations. This marked a significant milestone as the first orally administered HER2-targeted kinase inhibitor approved for this specific genetic subgroup of lung cancer patients, offering a more targeted and potentially less toxic therapy option compared with broader-acting agents
• In September 2025, the FDA approved imlunestrant (Inluriyo), a novel oral selective estrogen receptor degrader (SERD), for postmenopausal women and men with ER-positive, HER2-negative metastatic breast cancer harboring ESR1 mutations after progression on endocrine therapy. Although not exclusively a HER-targeted drug, its approval represents the expanding landscape of oral targeted therapies influencing treatment strategies in cancer subtypes where HER pathway interactions and receptor cross-talk play clinical roles
• In April 2025, in clinical development and regulatory progression, CAR-T and ADC-combination studies involving disitamab vedotin (RC48) gained attention for HER2-targeted therapy across multiple indications, including breast cancer and urothelial carcinoma. Although originally approved in China for HER2-positive gastric cancer in 2021, its ongoing combination trials with immune checkpoint inhibitors in other solid tumors highlight ongoing expansion and optimization of HER2-directed oral and related targeted drug regimens globally
