The European Medicines Agency (EMA) has accepted for review Mylan's marketing authorisation application (MAA) for a proposed biosimilar Trastuzumab, MYL-1401O, to treat certain human epidermal growth factor receptor 2 (HER2)-positive breast and gastric cancers.
Co-developed under the partnership between Mylan and India-based Biocon, Trastuzumab is indicated for the treatment of certain HER2-positive early stage and metastatic breast cancer, as well as HER2-positive metastatic gastric cancer.
Mylan noted that nearly two million women are diagnosed with breast cancer every year, with HER2-positive breast cancer being an aggressive form of breast cancer.
The MAA has been submitted based on analytical, functional and pre-clinical data, as well as results from the pharmacokinetics (PK) and confirmatory efficacy / safety global clinical trials for Trastuzumab.
Additionally, the filing includes data from the Heritage study, a Phase III double-blind, randomised clinical trial that evaluated comparative efficacy and safety of the proposed biosimilar, MYL-1401O, versus branded trastuzumab.
Mylan president Rajiv Malik said: "The acceptance of our regulatory submission of our proposed biosimilar Trastuzumab in Europe is another example of the strong progress we continue to make across our broad biosimilars portfolio.
