Takeda Priority BLA for Clotting Disorder
FDA has accepted for priority review a Takeda BLA for TAK-755, an enzyme replacement therapy for treating congenital thrombotic thrombocytopenic purpura, an ADAMTS13 deficiency disorder. The ultra-rare clotting disorder is caused by a deficiency in ADAMTS13 protease, the company says, adding that the mortality rate, if left untreated, is greater than 90%. Currently, there are no therapies specifically approved for prophylactic treatment, it says.
The BLA is based on data from a Phase 3 trial designed to evaluate the clinical benefit of TAK-755 across multiple clinically relevant endpoints, compared to plasma-based therapies. Interim results show that TAK-755 reduced the incidence of thrombocytopenia events by 60% compared to plasma-based therapy, Takeda says. “The proportion of subjects experiencing adverse events determined to be related to the treatment was substantially lower among subjects during treatment with TAK-755 (8.9%) compared to plasma-based therapies (47.7%),” it adds.
