FDA, approved lusutrombopag (Mulpleta, Shionogi Inc.) for thrombocytopenia in adults with chronic liver disease who are scheduled to undergo a medical or dental procedure.
Approval was based on two randomized, double-blind, placebo-controlled trials (L-PLUS 1 and L-PLUS 2, NCT02389621) involving 312 patients with chronic liver disease and severe thrombocytopenia who were undergoing an invasive procedure and had a platelet count less than 50 x 109/L. Patients were randomized 1:1 to receive 3 mg of lusutrombopag or placebo once daily for up to 7 days.
In L-PLUS 1, 78% of patients (38/49) receiving lusutrombopag required no platelet transfusion prior to the primary invasive procedure, compared with 13% (6/48) who received placebo (95% CI for treatment difference: 49%, 79%; p<0.0001). In L-PLUS 2, 65% (70/108) of patients who received lusutrombopag required no platelet transfusion prior to the primary invasive procedure or rescue therapy for bleeding from randomization through 7 days after the procedure, compared with 29% (31/107) receiving placebo (95% CI for treatment difference: 25%, 49%; p<0.0001).
The most common adverse reaction in ≥ 3% of patients was headache.
The recommended lusutrombopag dosage is 3 mg orally once daily with or without food for 7 days.
FDA granted this application priority review and fast track designation. A description of FDA expedited programs is in the Guidance for Industry: Expedited Programs for Serious Conditions-Drugs and Biologics.
