May 21st, 2018: DOPTELET receives FDA approval THE FIRST THERAPEUTIC AGENT FOR THE TREATMENT OF THROMBOCYTOPENIA IN ADULT PATIENTS WITH CHRONIC LIVER DISEASE PRIOR TO PLANNED PROCEDURES 5
DOPTELET Indication Indication: DOPTELET (avatrombopag) is a thrombopoietin receptor agonist indicated for the treatment of thrombocytopenia in adult patients with chronic liver disease who are scheduled to undergo a procedure. 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 Most common adverse reactions ( 3%) are: pyrexia, abdominal pain, nausea, headache, fatigue, and edema peripheral.
