Novo Nordisk is pleased to announce that the US Food and Drug Administration (FDA) has approved TRETTENĀ® (Coagulation Factor XIII A-Subunit [Recombinant]) for the routine prophylaxis of bleeding in people with congenital factor XIII (FXIII) A-subunit deficiency, one of the rarest inherited bleeding disorders. TRETTENĀ® is the only recombinant treatment for the disease. Patients with congenital FXIII A-subunit deficiency have a lifelong susceptibility towards bleeding, including spontaneous bleeding into the brain called intracranial hemorrhage, which, if not treated, could be life-threatening.1 TRETTENĀ® has been proven safe and effective and will offer patients once-monthly dosing with a short infusion time.

The FDA approved TRETTENĀ® based on results from a clinical program that demonstrated the safety and efficacy of TRETTENĀ®. The phase 3 trial that included 41 patients showed that when compared with a historic control group of individuals who did not receive routine FXIII infusions, preventive treatment with monthly 35 IU/kg TRETTENĀ® injections significantly decreased the number of bleeding episodes that required treatment.

The approval of TRETTENĀ® is another example of Novo Nordiskā€™s commitment to bringing new treatment options to people living with rare bleeding disorders. At this time, we anticipate TRETTENĀ® will be available in early 2014.

We are providing this information to you in the event patients or caregivers contact you with questions about TRETTENĀ®.
