Dova Pharma sNDA for Doptelet in ITP

Share

FDA has accepted a Dova Pharmaceuticals supplemental NDA for Doptelet (avatrombopag) for a new indication — treating chronic immune thrombocytopenia (ITP) in patients who have had an insufficient response to a previous treatment. ITP is an autoimmune bleeding disorder characterized by thrombocytopenia (low platelets level). The second generation, orally administered thrombopoietin receptor agonist was originally approved in May for treating thrombocytopenia in adult patients with chronic liver disease who are scheduled to undergo a procedure. The agency has set a user fee review action target date of 6/30/2019.


The submission is supported by safety and efficacy data from one pivotal randomized, placebo-controlled Phase 3 clinical trial in the target indication that met its primary and first secondary endpoints. “Data from all 24 studies in the avatrombopag clinical development program support the safety and tolerability of avatrombopag across multiple indications,” the company says.
