FDA expands Doptelet approval to ITP patients with thrombocytopenia


The Food and Drug Administration has approved a supplemental New Drug Application expanding the indication of avatrombopag (Doptelet) to include treatment of thrombocytopenia in adults with chronic immune thrombocytopenia (ITP) with insufficient response to previous therapy, according to Dova Pharmaceuticals.

FDA approval was based on results of a phase 3 trial in which a majority of patients who received avatrombopag achieved a platelet count of at least 50,000 per mcg after 8 days of therapy. In addition, efficacy was superior to patients in the placebo group in the maintenance of platelet counts during the 6-month treatment period.

Avatrombopag – an oral, thrombopoietin receptor agonist administered with food – was previously indicated for the treatment of chronic liver disease in adult patients who are scheduled to undergo a procedure. The most common adverse reactions in patients with ITP include headache, fatigue, contusion, epistaxis, upper respiratory tract infection, arthralgia, gingival bleeding, petechiae, and nasopharyngitis.
