Key clinical point: Once-daily treatment with oral avatrombopag significantly reduced the need for platelet transfusion and rescue therapy for up to 7 days after patients with chronic liver disease and thrombocytopenia underwent scheduled procedures.
Major finding: In the ADAPT-1 trial, 66% of patients in the 60-mg arm met this primary endpoint, as did 88% of patients who received 40 mg for less severe thrombocytopenia versus 23% and 38% of the placebo arms, respectively (P less than .001 for each comparison). In the ADAPT-2 trial, 69% of the 60-mg group met the primary endpoint, as did 88% of the 40-mg group versus 35% and 33% of the respective placebo groups (P less than .001 for each comparison).
Study details: ADAPT-1 and ADAPT-2, international, randomized, double-blind, placebo-controlled, phase III trials.
