FDA approves Doptelet for liver disease patients undergoing procedures


Doptelet (avatrombopag) is the first drug to be approved by the Food and Drug Administration for thrombocytopenia in adults with chronic liver disease who are scheduled to undergo a medical or dental procedure, the FDA announced in a statement.

“Patients with chronic liver disease who have low platelet counts and require a procedure are at increased risk of bleeding,” said Richard Pazdur, MD, director of the FDA’s Oncology Center of Excellence and acting director of the Office of Hematology and Oncology Products in the FDA’s Center for Drug Evaluation and Research. “Doptelet was demonstrated to safely increase the platelet count. This drug may decrease or eliminate the need for platelet transfusions, which are associated with risk of infection and other adverse reactions.”

Thrombocytopenia can lead to serious or life-threatening bleeding during invasive procedures. Patients with significant thrombocytopenia typically receive platelet transfusions immediately prior to such procedures.

The safety and efficacy of two different doses of Doptelet administered orally over 5 days, as compared with placebo, was studied in the ADAPT trials (ADAPT-1 and ADAPT-2) involving 435 patients with chronic liver disease and severe thrombocytopenia who were scheduled to undergo a procedure that would typically require platelet transfusion. At both dose levels of Doptelet, a higher proportion of patients had increased platelet counts and did not require platelet transfusion or any rescue therapy on the day of the procedure and up to 7 days following the procedure as compared with those treated with placebo.

The most common side effects reported by clinical trial participants who received Doptelet were fever, stomach (abdominal) pain, nausea, headache, fatigue and edema in the hands or feet. People with chronic liver disease and people with certain blood clotting conditions may have an increased risk of developing blood clots when taking Doptelet, the FDA said in a press release announcing the approval.

The FDA granted the Doptelet approval to AkaRx.
