FDA Accepts Accord’s Herceptin Biosimilar BLA
FDA has accepted for review an Accord BioPharma BLA for HLX02, a proposed trastuzumab (Roche’s Herceptin) biosimilar for adjuvant treatment of HER2-overexpressing breast cancer, the treatment of HER2-overexpressing metastatic breast cancer, and the treatment of HER2-overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma.
The submission, according to Accord, is based on “robust structural and functional analytical comparison data using multiple orthogonal techniques and head-to-head clinical studies between HLX02 and the reference trastuzumab, including comparative analytical studies, nonclinical studies, a Phase 1 PK similarity study and a global multicentric phase 3 safety, efficacy and immunogenicity study in relevant patient populations, which compared HLX02 to the reference trastuzumab.” Data reportedly demonstrated that HLX02 and reference trastuzumab are similar in quality, safety, and efficacy.
HLX02 was first developed by Accord’s China-based business partner Shanghai Henlius. In 2021, Henlius granted Accord BioPharma the exclusive rights to develop and commercialize HLX02 in the U.S. and Canada.
