Teijin Pharma Launches Revcovi®, Japan’s First Drug for ADA Deficiency

Tokyo, Japan --- Teijin Pharma Limited, the core company of the Teijin Group's healthcare business, announced today that it has launched Revcovi 2.4 mg for intramuscular injection [Elapegademase (Genetical Recombination)], effective immediately. Revcovi 2.4 mg, Japan's first drug for Adenosine deaminase (ADA) deficiency, is an enzyme replacement therapy that is expected to improve ADA activity and the immune system of ADA-deficiency patients.


ADA, an ultra-rare disease caused by a lack of ADA activity due to gene mutations, leads to infections and impaired growth resulting from severe combined immunodeficiency. The first-line treatment option for ADA deficiency is hematopoietic stem cell transplantation, and other options include administration of ADA for enzyme replacement therapy to improve immune functions.


Teijin Pharma concluded an exclusive development and marketing agreement with Leadiant Biosciences Limited (formerly known as Sigma-Tau Pharma Ltd.) in 2014, back when no drug for ADA enzyme replacement therapy had been approved. Marketing approval for the indication of ADA deficiency was received from Japan's Ministry of Health, Labor and Welfare (MHLW) this past March.


Going forward, Teijin Pharma will market Revcovi 2.4 mg to contribute to the quality of life of ADA-deficiency patients.
