Historic Approval for Breast Cancer Treatment

Shanghai Henlius Biotech (2696.HK) and Organon (NYSE: OGN) announced April 29, 2026, that the European Commission has granted marketing authorization for POHERDY® (pertuzumab) 420 mg/14 mL injection, making it the first approved biosimilar to PERJETA® (pertuzumab) in Europe.

The approval encompasses all indications of the reference product, positioning POHERDY as a potentially more accessible treatment option for patients with HER2-positive breast cancer across European markets.

EMA and MHRA are the agencies to watch. Regulatory relevance reads medium for pharmaceutical intelligence. Teams should track submission types, designations, and guidance shifts that could move approval timelines.

Market Impact and Patient Access

This regulatory milestone represents a significant development in the European biosimilar landscape. Pertuzumab, originally developed as PERJETA, is a critical component in treating HER2-positive breast cancer, often used in combination with trastuzumab and chemotherapy.

The introduction of POHERDY could substantially reduce treatment costs while maintaining therapeutic efficacy, potentially expanding patient access to this essential oncology medication. Healthcare systems across Europe may benefit from increased competition in the pertuzumab market.
