FDA assigns Prescription Drug User Fee Act (PDUFA) target action date of August 13, 2024
CRANFORD, NJ, USA I March 18, 2024 I Citius Pharmaceuticals, Inc. (“Citius” or the “Company”) (Nasdaq: CTXR), a late-stage biopharmaceutical company dedicated to the development and commercialization of first-in-class critical care products today announced that the U.S. Food and Drug Administration (FDA) has accepted the resubmission of the Company’s Biologics License Application (BLA) for LYMPHIR™ (denileukin diftitox), an IL-2-based immunotherapy for the treatment of patients with relapsed or refractory cutaneous T-cell lymphoma (CTCL) after at least one prior systemic therapy. The FDA has assigned a PDUFA goal date of August 13, 2024.
“The acceptance of the BLA resubmission reflects the completeness of our response to the enhanced product testing and additional controls highlighted by the FDA in their July 2023 CRL. No concerns relating to safety or efficacy were noted in the letter, and we remain confident in the robustness of the clinical data package included with the initial BLA submission,” stated Leonard Mazur, Chairman and CEO of Citius.
“We believe there remains a critical unmet need for an additional viable treatment option for patients with relapsed or refractory CTCL as current therapies are non-curative. We are grateful for the FDA’s vital support for rare disease drug development as we work to expand treatment options for patients with cutaneous T-cell lymphoma. We look forward to the FDA’s decision and the potential benefit LYMPHIR may provide patients with relapsed or refractory CTCL,” added Mazur.
The BLA is supported by a pivotal Phase 3 study (NCT01871727). The resubmission follows dialog with the FDA resulting from a Complete Response Letter (CRL) received on July 28, 2023. Citius believes it has addressed enhanced product testing and additional manufacturing controls noted in the letter. There were no safety or efficacy issues cited and no additional trials required.
About LYMPHIR™ (denileukin diftitox-cxdl)
LYMPHIR 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. In 2011 and 2013, the FDA granted orphan drug designation to LYMPHIR for the treatment of PTCL and CTCL, respectively. In 2021, denileukin diftitox received regulatory approval in Japan for the treatment of CTCL and peripheral T-cell lymphoma (PTCL). Subsequently, in 2021, Citius acquired an exclusive license with rights to develop and commercialize LYMPHIR in all markets except for Japan and certain parts of Asia.
About Cutaneous T-cell Lymphoma
Cutaneous T-cell lymphoma is a type of cutaneous non-Hodgkin lymphoma (NHL) that comes in a variety of forms and is the most common type of cutaneous lymphoma. In CTCL, T-cells, a type of lymphocyte that plays a role in the immune system, become cancerous and develop into skin lesions, leading to a decrease in the quality of life of patients with this disease due to severe pain and pruritus. Mycosis Fungoides (MF) and Sézary Syndrome (SS) comprise the majority of CTCL cases. Depending on the type of CTCL, the disease may progress slowly and can take anywhere from several years to upwards of ten to potentially reach tumor stage. However, once the disease reaches this stage, the cancer is highly malignant and can spread to the lymph nodes and internal organs, resulting in a poor prognosis. Given the duration of the disease, patients typically cycle through multiple agents to control disease progression. CTCL affects men twice as often as women and is typically first diagnosed in patients between the ages of 50 and 60 years of age. Other than allogeneic stem cell transplantation, for which only a small fraction of patients qualify, there is currently no curative therapy for advanced CTCL.
About Citius Pharmaceuticals, Inc.
Citius Pharma is a late-stage biopharmaceutical company dedicated to the development and commercialization of first-in-class critical care products. The Company’s diversified pipeline includes two late-stage product candidates. At the end of 2023, Citius completed enrollment in a Phase 3 Pivotal superiority trial of Mino-Lok®, an antibiotic lock solution to salvage catheters in patients with catheter-related bloodstream infections. A Biologics License Application for LYMPHIR™, a novel IL-2R immunotherapy for an initial indication in the treatment of cutaneous T-cell lymphoma, is currently under review by the FDA with August 13, 2024 assigned as the PDUFA target action date. Citius previously announced plans to form Citius Oncology, a standalone publicly traded company with LYMPHIR as its primary asset. LYMPHIR received orphan drug designation by the FDA for the treatment of CTCL and PTCL. In addition, Citius completed enrollment in its Phase 2b trial of CITI-002 (Halo-Lido), a topical formulation for the relief of hemorrhoids. For more information, please visit www.citiuspharma.com.
