Takeda gets ADZYNMA FDA approval for cTTP treatment: A new era in rare disease therapy


Takeda has achieved a monumental milestone in rare disease therapy with the U.S. Food and Drug Administration’s approval of ADZYNMA (ADAMTS13, recombinant-krhn) for the treatment of congenital thrombotic thrombocytopenic purpura (cTTP). This approval marks ADZYNMA as the first and only FDA-approved recombinant ADAMTS13 protein, addressing a critical unmet medical need in people with cTTP by replacing the deficient ADAMTS13 enzyme.

A New Hope for cTTP Patients

cTTP is an ultra-rare, life-threatening blood clotting disorder linked to a deficiency in the ADAMTS13 enzyme. It manifests in severe symptoms like thrombocytopenia and microangiopathic hemolytic anemia. Historically, acute TTP events had a mortality rate of over 90% when left untreated. The introduction of ADZYNMA brings new hope to patients and the medical community, offering a targeted and effective treatment option.

Clinical Trial Success and Efficacy

The FDA’s approval of ADZYNMA was grounded in comprehensive evidence from a randomized, controlled, open-label Phase 3 trial and a continuation trial. The trials demonstrated that patients receiving ADZYNMA prophylactically experienced significantly fewer acute and subacute TTP events compared to those on plasma-based therapies. This finding underlines the drug’s efficacy in preventing life-threatening complications associated with cTTP.
