概览

Oprelvekin is a form of recombinant interleukin-11 used to stimulate production of megakaryocytes and platelets in patients with or at risk of thrombocytopenia after chemotherapy.

作用机制

Oprelvekin binds to the interleukin 11 receptor which leads to a cascade of signal transduction events. Its pharmacological action mimics the biological activity of endogenous IL-11, which is a thrombopoietic growth factor that directly stimulates the proliferation of hematopoietic stem cells and megakaryocyte progenitor cells and induces megakaryocyte maturation resulting in increased platelet production.

适应症

Indicated for the prevention of severe thrombocytopenia and the reduction of the need for platelet transfusions following myelosuppressive chemotherapy in adult patients with nonmyeloid malignancies who are at high risk of severe thrombocytopenia.[Label]

• Severe Thrombocytopenia
