Dova Pharmaceuticals Announces Availability of DOPTELET® in the United States

DURHAM, N.C., May 31, 2018 (GLOBE NEWSWIRE) -- Dova Pharmaceuticals, Inc. (NASDAQ:DOVA) today announced the availability of DOPTELET in the United States for the treatment of thrombocytopenia in adult patients with chronic liver disease (CLD) who are scheduled to undergo a procedure. DOPTELET was approved by the U.S. Food and Drug Administration (FDA) on May 21, 2018.

“Dova is proud to launch our first commercial product in the United States, with DOPTELET being the first orally administered treatment option for thrombocytopenia in patients with chronic liver disease,” said Alex C. Sapir, President and Chief Executive Officer. “We remain committed to ensuring access to DOPTELET through Dova 1Source, our physician and patient reimbursement support center.”

DOPTELET can now be ordered for patients through a network of Specialty Pharmacies. The Wholesale Acquisition Cost (WAC) for DOPTELET is $9,000 for the 40mg daily dose and $13,500 for the 60mg daily dose. At launch, through Dova 1Source, Dova will be providing a host of reimbursement support programs so that no eligible patient is denied DOPTELET for financial reasons.

About Thrombocytopenia in Chronic Liver Disease

Thrombocytopenia, a reduction in the number of platelets in the blood, is a common complication in patients with CLD, with the extent of thrombocytopenia often worsening with the severity of liver disease. TPO, the principal physiologic regulator of platelet production, is made in the liver and stimulates bone marrow production of platelets, which are critical blood components for controlling bleeding. As a result of damage to the liver in patients with CLD, TPO production is reduced, which consequently results in decreased platelet production and thrombocytopenia.

There are approximately 70,000 patients with CLD that have a platelet count of less than 50,000/µL. These patients typically require 1 to 3 invasive diagnostic and therapeutic procedures per year; each of these procedures carry a risk of bleeding. If not effectively treated, thrombocytopenia can lead to serious uncontrolled bleeding, resulting in prolonged hospitalizations and other post-procedure complications.


DOPTELET (avatrombopag) is a second generation, once daily, orally administered TPO receptor agonist approved for the treatment of thrombocytopenia in adult patients with CLD who are scheduled to undergo a procedure. DOPTELET is designed to mimic the effects of TPO, the primary regulator of normal platelet production.

Two global Phase 3, double-blind, placebo-controlled trials (ADAPT-1 [N=231] and ADAPT-2 [N=204]), conducted in adults with thrombocytopenia (platelet count of less than 50,000/µL) and CLD, supported FDA approval. Patients were assigned to either 40 mg or 60 mg of avatrombopag daily for 5 days based on their Baseline platelet counts (40 to <50,000/mL or <40,000/mL, respectively). Avatrombopag was shown to be superior to placebo in increasing the proportion of patients not requiring platelet transfusions or rescue procedures for bleeding up to 7 days following a scheduled procedure in both trials in both the 40 mg (ADAPT-1, 88% vs. 38%, p <0.0001; ADAPT-2, 88% vs. 33%; p<0.0001), and 60 mg (ADAPT-1, 66% vs. 23%, p <0.0001; ADAPT-2, 69% vs. 35%; p=0.0006) treatment groups. Avatrombopag was also superior to placebo at the two secondary efficacy endpoints in each trial. In the avatrombopag treatment groups, there was an increased proportion of patients achieving the target platelet count of ≥50,000/mL on Procedure Day, and a greater magnitude of the change in mean platelet count from Baseline to Procedure Day; all treatment differences between the avatrombopag and placebo treatment groups were highly statistically significant with p values <0.0001. The most common adverse reactions with avatrombopag included pyrexia, abdominal pain, nausea, headache, fatigue, and edema peripheral. Portal vein thromboses have been reported in patients with CLD and in patients receiving TPO receptor agonists. One treatment-emergent event of portal vein thrombosis was reported in the ADAPT trials in an avatrombopag-treated patient.

Dova has also submitted a marketing authorization application (MAA) to the European Medicines Agency (EMA) for DOPTELET for the treatment of patients with thrombocytopenia and CLD scheduled to undergo a procedure and plans to submit a supplemental NDA to FDA for the treatment of chronic immune thrombocytopenia purpura (ITP) in the second half of 2018. Work is also ongoing for evaluation of DOPTELET in the treatment of chemotherapy-induced thrombocytopenia (CIT) and for the treatment of thrombocytopenia in patients undergoing more invasive surgical procedures. Dova holds the worldwide intellectual property rights to avatrombopag for all current and future indications.

Indication and Important Safety Information


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



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.




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