IMPORTANT SAFETY INFORMATION FOR DOPTELET
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 or chronic immune thrombocytopenia. Portal vein thrombosis has been reported in patients with chronic liver disease, and thromboembolic events (arterial and venous) have been reported in patients with chronic immune thrombocytopenia treated with TPO receptor agonists.
In clinical trials, 0.2% (1/430) of patients with chronic liver disease treated with DOPTELET developed a treatment-emergent event of portal vein thrombosis. In clinical trials in patients with chronic immune thrombocytopenia, 7% (9/128) of patients treated with DOPTELET developed a thromboembolic event.
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 or chronic immune thrombocytopenia in an attempt to normalize platelet counts. Follow the dosing guidelines to achieve target platelet counts.
The most common adverse reactions (≥3%) in patients with chronic liver disease were: pyrexia, abdominal pain, nausea, headache, fatigue, and peripheral edema.
The most common adverse reactions (≥10%) in patients with chronic immune thrombocytopenia were: headache, fatigue, contusion, epistaxis, upper respiratory tract infection, arthralgia, gingival bleeding, petechiae, and nasopharyngitis.
