Signing Ceremony of Exclusive Commercial Collaboration between Belief BioMed and Takeda China


Dr. Xiao Xiao, Co-founder, Chairman and Chief Science Officer of Belief BioMed, said, “Belief BioMed focuses on the cutting-edge gene therapy field, with our product pipeline covering a wide range of rare and common diseases, striving to fill a large number of unmet clinical needs. BBM-H901 is one of the blockbuster products independently developed and produced by Belief BioMed, and it is the first adeno-associated virus (AAV)-based therapy under registrational clinical trials for the treatment of hemophilia B in China. We are very pleased to have announced this collaboration with Takeda China during the 2023 INTERNATIONAL BIOPHARMA INDUSTRY WEEK, and we believe that combining Belief BioMed’s solid clinical development capabilities and Takeda China’s strong commercialization experiences, together we will accelerate the accessibility of this innovative drug and work together to bring more innovative treatment solutions to the patients in China.”

Hemophilia B is a genetic disorder caused by the deficiency of factor IX (FIX), and it is marked by repeated, spontaneous bleeding episodes within joints, muscles, and soft tissues, often enduring for prolonged periods. Left unmanaged, it can culminate in joint deformity, muscle atrophy, and, in severe cases, fatal outcomes. In China, there are an estimated 3,800 registered cases of patients with hemophilia B1. Presently, patients with hemophilia B in China face multiple challenges, including limited treatment options and a lack of standardized diagnostic and therapeutic procedures. Most patients rely on prothrombin complex concentrate (PCC) as a replacement therapy, despite the risk of exposure to infection, together with inconvenient administration. Furthermore, due to low adoption rate and insufficient dosage of treatment, joint bleeds and joint deformity are commonly observed in patients with moderate-to-severe hemophilia B. Consequently, there is a pressing unmet need for medical care among these patients.


BBM-H901 is a gene therapy, independently developed and produced by Belief BioMed. It is administered intravenously to introduce the human factor Ⅸ (FⅨ) gene into the body of hemophilia B patient, thereby improving and maintaining the levels of coagulation factors in the patient's body for a long time, and in order to achieve the prevention of bleeding. It is also the first AVV-based therapy under registrational clinical trials for the treatment of hemophilia B in China. At present, the dosing to subjects in Phase III registration clinical trial has been successfully completed2. In 2022, the results of clinical studies related to BBM-H901 were successively published in two prestigious international journals, i.e. The Lancet Haematology and New England Journal of Medicine. In the same year, BBM-H901 was granted Breakthrough Therapy Designation (BTD) by China Center for Drug Evaluation (CDE), NMPA.


The clinical study published in The Lancet Hematology (NCT04135300) is an investigator-initiated, single-center, single-arm clinical trial designed to evaluate the safety and efficacy of a single intravenous infusion of BBM-H901. According to their findings, patients with hemophilia B over 18 years of age with FIX residual levels ≤2IU/ dl who received BBM-H901 injection at 58 weeks of follow-up showed: The median annual bleeding rate was reduced from 12 to 0 (p=0.0092), the median number of target joints was reduced from 1.5 to 0 (p=0.0031), and the median annual infusions of factor IX were reduced from 53.5 to 0 (p<0.0001). There were no serious adverse events during follow-up, and no grade 3-4 adverse events. Grade 1-2 adverse events associated with BBM-H901 included fever (1 case [10%]) and elevated aminotransferase (1 case [10%])3.


The collaboration with Belief BioMed is an important milestone that will further enrich our existing product portfolios. “By combining the R&D technology of Belief BioMed with Takeda China's extensive experience and expertise in commercialization, we can accelerate the pace of bringing breakthrough gene therapies to more patients”, Sean Shan, Senior Vice President of Takeda Pharmaceutical Company and President of Takeda, said. “The local advanced gene therapy technology as that developed by Belief BioMed is emerging rapidly day by day, and we are convinced that China's pharmaceutical innovation will fast integrate into the world in the future and become the innovation source of global biomedical technology.”
