Frank Nocken: FDA Approves Caplacizumab Therapy for Pediatric Acquired TTP

Frank Nocken, Independent Consultant for Scientific Innovation Management, shared a post on LinkedIn:

” ‘The FDA has approved Cablivi (caplacizumab) for injection to treat pediatric patients aged 12 years and older with acquired thrombotic thrombocytopenic purpura (aTTP), in combination with plasma exchange and immunosuppressive therapy.’

Caplacizumab therapy is nanobody-based and built on small antibody fragments derived from heavy-chain-only antibodies, that targets von Willebrand factor, a protein that plays a central role in platelet adhesion and clot formation in aTTP.

It works by binding to the A1 domain of von Willebrand factor, blocking its interaction with platelets and helping to reduce the microvascular clots that define the disease.’ ”
