SHANGHAI, China & JERSEY CITY, NJ – April 29, 2026 – Shanghai Henlius Biotech, Inc. (2696.HK), and Organon (NYSE: OGN) today announced the European Commission (EC) has granted marketing authorization for POHERDY® (pertuzumab) 420 mg/14 mL injection for intravenous use, the first and only approved biosimilar to PERJETA (pertuzumab) in Europe, for all indications of the reference product.1
“As the first, and currently the only, pertuzumab biosimilar in Europe, the EC’s approval of POHERDY marks an important milestone in expanding access to treatments for patients with certain HER2-positive breast cancers, particularly as breast cancer is the most commonly diagnosed cancer among women and the leading cause of cancer related deaths among women in the European Union,” said Joe Azzinaro, Vice President, Global Commercial Lead Biosimilars, at Organon.2,3 “Organon’s growing global portfolio of biosimilars reinforces our ongoing commitment to supporting the sustainability of health care systems while advancing women’s health through access to quality medicines.”3,4
“Building on POHERDY’s FDA approval in the United States as the country’s first pertuzumab biosimilar, this EU approval further expands our growing portfolio of approved biosimilar medicines in markets around the world and is a testament to our strong collaboration with Organon,” said Ping Cao, Chief Business Development Officer and Senior Vice President of Henlius. “Guided by our commitment to scientific excellence and product quality, we are working to expand access to additional treatment options for the benefit of patients and the health care system.”
In Europe, POHERDY is indicated in combination with trastuzumab and docetaxel for the treatment of adults with HER2-positive metastatic or locally recurrent unresectable breast cancer, who have not received prior anti-HER2 therapy or chemotherapy for metastatic disease. POHERDY is also indicated for use in combination with trastuzumab and chemotherapy as (i) neoadjuvant treatment of adults with HER2-positive, locally advanced, inflammatory, or early stage breast cancer at high risk of recurrence and (ii) adjuvant treatment of adults with HER2-positive early breast cancer at high risk of recurrence.
POHERDY was approved based on the review of a comprehensive data package, which included structural and functional analytical data, clinical pharmacokinetic data, and comparative clinical studies demonstrating that POHERDY is a biological medicine highly similar to the reference product based on a totality of evidence, including analytical, pharmacokinetic, efficacy, safety, and immunogenicity data (the intrinsic ability of proteins and other biological medicines to cause an immune response).5
In 2022, Henlius entered into a license and supply agreement with Organon, granting Organon the exclusive commercialization rights to several biosimilars, including POHERDY. The agreement covers exclusive global commercialization rights except for China.6
