Incyte Pulling Parsaclisib NDA

Share

Incyte says that after discussions with FDA, it has made a business decision to withdraw its NDA for parsaclisib to treat patients with relapsed or refractory follicular lymphoma, marginal zone lymphoma, and mantle cell lymphoma. The company says its decision followed discussions with FDA about confirmatory studies needed to support an accelerated approval. Incyte says it determined the studies could not be completed within a period that would support the investment. It says the withdrawal of the NDA is not related to any changes in the drug’s safety or efficacy.

Parsaclisib is described as a potent, highly selective, next-generation investigational novel oral inhibitor of phosphatidylinositol 3-kinase delta. It is currently under evaluation as a monotherapy in Phase 2 trials to treat non-Hodgkin lymphomas and in a Phase 3 study for autoimmune hemolytic anemia, Incyte says. The company says pivotal trials of parsaclisib in combination with ruxolitinib to treat patients with myelofibrosis also are underway.
