New FDA Approvals: FDA Approved Citius’ Lymphir for CTCL

Aug. 7: The FDA approved Citius Pharmaceuticals, Inc.’s Lymphir (denileukin diftitox-cxdl) for the treatment of relapsed or refractory cutaneous T-cell lymphoma (CTCL) after at least one systemic therapy. The immunotherapy is the only CTCL treatment that targets the interleukin-2 (IL-2) receptor found in T-cell lymphomas and regulatory T cells (Tregs). The rare disease is a chronic non-Hodkin lymphoma that primarily affects the skin. The drug is a reformulation of Ontak (denileukin diftitox), which was on the U.S. market from 2008 to 2014, when it was voluntarily withdrawn “to enable manufacturing improvements.” The FDA gave the therapy orphan drug designation. The recommended dose is 9 mcg/kg per day based on actual body weight via a 60-minute intravenous infusion on days one through five of a 21-day cycle. The company says it expects to launch the agent within the next five months.
