China National Medical Products Administration Approves DOPTELET® (avatrombopag) for the treatment of thrombocytopenia in adult patients with chronic liver disease who are scheduled to undergo a procedure

DURHAM, N.C., April 30, 2020 /PRNewswire/ -- AkaRx, Inc., a wholly owned subsidiary of Dova Pharmaceuticals, Inc, a Swedish Orphan Biovitrum AB (publ) (Sobi™) company, today announced DOPTELET^® (avatrombopag) has been granted approval from the China National Medical Products Administration (NMPA) for the treatment of thrombocytopenia in adult patients with chronic liver disease (CLD) who are scheduled to undergo a procedure (i.e., the CLD indication).

"We are pleased DOPTELET is now approved in China for the treatment of thrombocytopenia in patients with CLD ahead of a planned procedure, a routine consequence of the disease," said Mahmood Ladha, President and Head of Dova. "Receiving the approval for DOPTELET from the China NMPA marks another significant milestone for Dova and our growing leadership in the global treatment of thrombocytopenia. DOPTELET is the first treatment for this indication approved in China, offering patients a safe and effective orally-administered alternative to platelet transfusions for increasing platelet counts to the target level."

The approval was based on safety and efficacy data from two global Phase 3, double-blind, placebo-controlled trials, conducted in adults with severe thrombocytopenia (platelet count of less than 50,000/µL) and CLD. Both studies showed DOPTELET to be superior to placebo, in both the 40 mg and 60 mg treatment groups, in increasing the proportion of patients not requiring platelet transfusions or rescue procedures for bleeding up to 7 days following a scheduled procedure. DOPTELET was also shown to be superior to placebo in both secondary efficacy endpoints in each trial, i.e., the proportion of patients achieving a platelet count equal to or greater than 50,000/µL and the magnitude of the change in platelet counts from baseline to procedure day.

DOPTELET has received marketing approval for the CLD indication from the U.S. Food and Drug Administration (FDA) and the European Medicines Agency. DOPTELET is also approved by the FDA for the treatment of thrombocytopenia in adult patients with chronic immune thrombocytopenia (ITP) who have had an insufficient response to a previous treatment. Jiangsu Wanbang Pharmaceutical Marketing and Distribution Co., Ltd., a subsidiary of Shanghai Fosun Pharmaceutical Industrial Development Co., Ltd, has exclusive rights to distribute DOPTELET in China under a marketing and distribution agreement with AkaRx, Inc.

Indication and Important Safety Information (as approved in China)

INDICATION

DOPTELET (avatrombopag) is indicated for the treatment of thrombocytopenia in adult patients with chronic liver disease who are scheduled to undergo a procedure.

SELECTED IMPORTANT SAFETY INFORMATION

Warnings and Precautions

DOPTELET is a thrombopoietin (TPO) receptor agonist and TPO receptor agonists have been associated with thrombotic and thromboembolic complications in patients with chronic liver disease. Portal vein thrombosis has been reported in patients with chronic liver disease treated with TPO receptor agonists. In the ADAPT-1 and ADAPT-2 clinical trials, there was 1 treatment- emergent event of portal vein thrombosis in a patient (n=1/430) with chronic liver disease and thrombocytopenia treated with DOPTELET. Consider the potential increased thrombotic risk when administering DOPTELET to patients with known risk factors for thromboembolism, including genetic prothrombotic conditions (Factor V Leiden, Prothrombin 20210A, Antithrombin deficiency or Protein C or S deficiency).

DOPTELET should not be administered to patients with chronic liver disease in an attempt to normalize platelet counts.

Contraindications: None

Adverse Reactions

The most common adverse reactions (≥3%) were: pyrexia, abdominal pain, nausea, headache, fatigue, and edema peripheral.
