Sanofi announced that The European Commission has granted marketing authorization for Cablivi™ (caplacizumab) for the treatment of adults experiencing an episode of acquired thrombotic thrombocytopenic purpura (aTTP), a rare blood-clotting disorder.

Cablivi is the first therapeutic specifically indicated for the treatment of aTTP. aTTP is a life-threatening, autoimmune-based blood clotting disorder characterized by extensive clot formation in small blood vessels throughout the body, leading to severe thrombocytopenia (very low platelet count), microangiopathic hemolytic anemia (loss of red blood cells through destruction), ischemia (restricted blood supply to parts of the body) and widespread organ damage especially in the brain and heart.

Cablivi was developed by Ablynx, a Sanofi company. Sanofi Genzyme, the specialty care global business unit of Sanofi, will work with relevant local authorities to make Cablivi available to patients in need in countries across Europe.

Cablivi is the company’s first Nanobody®-based medicine to receive approval and the first newly approved product that will be part of Sanofi Genzyme’s Rare Blood Disorders franchise. Earlier this year, Sanofi acquired Bioverativ which has treatments for hemophilia A and B.

Caplacizumab is a bivalent anti-vWF Nanobody that received Orphan Drug Designation in Europe and the United States in 2009, in Switzerland in 2017 and in Japan in 2018. Caplacizumab blocks the interaction of ultralarge von Willebrand Factor (vWF) multimers with platelets and, therefore, has an immediate effect on platelet adhesion and the ensuing formation and accumulation of the micro-clots that cause the severe thrombocytopenia, tissue ischemia and organ dysfunction in aTTP.

The approval of Cablivi in the EU is based on the Phase II TITAN and Phase III HERCULES studies in 220 adult patients with aTTP. The efficacy and safety of caplacizumab in addition to standard-of-care treatment, daily PEX and immunosuppression, were demonstrated in these studies.
