[{"type":"text","content":"Prescription Drug User Fee Act (PDUFA) target action date is September 28, 2023 \nCRANFORD, N.J., Dec. 1, 2022 /PRNewswire/ -- Citius Pharmaceuticals, Inc. (\"Citius\" or the \"Company\") (Nasdaq: CTXR), a late-stage biopharmaceutical company developing and commercializing first-in-class critical care products, today announced that the U.S. Food and Drug Administration (FDA) has accepted the Company's Biologics License Application (BLA) for denileukin diftitox (\"I/ONTAK\" or \"E7777\"), an engineered IL-2-diphtheria toxin fusion protein for the treatment of patients with persistent or recurrent cutaneous T-cell lymphoma (CTCL). I/ONTAK is a purified and more bioactive formulation of previously FDA-approved ONTAKĀ®. The PDUFA target action date is September 28, 2023. The BLA is supported by a pivotal Phase 3 study (NCT01871727). \n\"The acceptance of the previously announced BLA submission for I/ONTAK is another important regulatory milestone for our oncology program. With an anticipated PDUFA date of September 28, 2023, we look forward to the potential approval of this therapeutic for patients with persistent or recurrent cutaneous T-cell lymphoma, a rare disease for which patients with advanced disease have limited treatment options,\" stated Leonard Mazur, Chairman and CEO of Citius.\nAbout I/ONTAK\nI/ONTAK is a recombinant fusion protein that combines the interleukin-2 (IL-2) receptor binding domain with diphtheria toxin fragments. The agent specifically binds to IL-2 receptors on the cell surface, causing diphtheria toxin fragments that have entered cells to inhibit protein synthesis. I/ONTAK, a purified version of denileukin diftitox, is a reformulation of previously FDA-approved oncology treatment ONTAK. ONTAK was marketed in the U.S. from 1999 to 2014, when it was voluntarily withdrawn from the market. Manufacturing improvements resulted in a new formulation which maintains the same amino acid sequence but features improved purity and bioactivity. The new formulation received regulatory approval in Japan in 2021 for the treatment of CTCL and peripheral T-cell lymphoma (PTCL). In 2011 and 2013, the FDA granted orphan drug designation to I/ONTAK for the treatment of PTCL and CTCL, respectively.\nAbout Cutaneous T-cell Lymphoma\nCutaneous T-cell lymphoma is a type of cutaneous non-Hodgkin lymphoma (NHL) that comes in a varie...
