FDA OKs Shionogi NDA for Mulpleta for Thrombocytopenia
FDA has approved a Shionogi NDA for Mulpleta (lusutrombopag), a once-daily, orally administered, small molecule thrombopoietin (TPO) receptor agonist for treating thrombocytopenia in adult patients with chronic liver disease who are scheduled to undergo a procedure. Approval was based on safety and efficacy data from two Phase 3 clinical trials, L-PLUS 1 and L-PLUS 2, in which Mulpleta met primary and secondary endpoints, the company says. Lusutrombopag interacts with the transmembrane domain of human TPO receptors expressed on megakaryocytes to induce the proliferation and differentiation of megakaryocytic progenitor cells from hematopoietic stem cells and megakaryocyte maturation.
