SHANGHAI,?June 21, 2019?/PRNewswire/ -- Henlius, a leading biotech company in?China?developing both biosimilar and innovative biologics, announced today that the European Medicines Agency (EMA) has officially accepted to review the Marketing Authorization Application (MAA) of its trastuzumab biosimilar HLX02. The European rights of this product have been out-licensed to its business partner Accord Healthcare. HLX02 is indicated for human epidermal growth factor receptor 2-positive (HER2+) early-stagebreast cancer, HER2+ metastatic breast cancer, and untreated HER2+ metastatic gastric and gastroesophageal junction (GEJ) cancer. The New Drug Application (NDA) of HLX02, a biosimilar of a classical targeted therapy for cancers, has been accepted for review by the National Medical Products Administration (NMPA) in?China. The acceptance for review by the EMA demonstrates that the "China-developed" biosimilar has entered the global stage with the hope to benefit patients globally. "We are very pleased to receive the EMA acceptance to review of our trastuzumab biosimilar HLX02 MAA submission," said Dr.?Scott Liu, co-Founder, President and CEO at Henlius. "It shows that our clinical, medical, regulatory affairs and quality system capabilities have been internationally recognized. We plan to work closely with EMA on this HLX02 MAA and hope to benefit HER2+ cancer patients globally with its high-quality and affordability." The Phase 3 study aimed for head-to-head similarity evaluation in efficacy, safety and immunogenicity profiles between HLX02 and reference trastuzumab sourced from the European Union (EU) in 649 previously untreated patients with HER2+ metastatic breast cancer in mainland?China,?Ukraine,?Poland?and?the Philippines. The Phase 1 study has successfully demonstrated the equivalence in pharmacokinetics and safety profiles between HLX02 and reference trastuzumab sourced from both EU and?China. Apart from the R&D and innovation efforts, Henlius is also actively creating new business models and expanding its global presence. The acceptance of the regulatory submission of trastuzumab biosimilar HLX02 MAA in?Europe?is another example of strong progress Henlius continues to make across the robust biosimilars portfolio. The acceptance of HLX02 MAA review marks a key milestone for the collaboration between Henlius and its partner Accord. In?June 2018, Henlius signed the licensing and supply agreements with Accord.
