CRANFORD, NJ, USA I September 28, 2022 I 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 Company has submitted a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) for denileukin diftitox (I/ONTAK), 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 ONTAK®. The BLA is supported by a pivotal Phase 3 study (NCT01871727). Results of the study were consistent with the prior FDA-approved formulation.
“The treatment of advanced cutaneous T-cell lymphoma remains a complex and challenging unmet medical need. Each year, thousands of patients are diagnosed with CTCL, a debilitating orphan disease with no single standard of care. Patients are often treated with multiple alternate therapies. Citius is proud to advance the only potential CTCL therapeutic with a mechanism of action that delivers a cytotoxic protein by binding to the IL-2 receptors found in malignant T-cells and immunosuppressive T-regulatory cells. We look forward to continuing to engage with the FDA as they review our BLA and bringing this treatment option to patients, if approved,” stated Leonard Mazur, Chairman and CEO of Citius. “The BLA filing for denileukin diftitox marks the first of our pipeline candidates to be submitted for FDA approval.”
About I/ONTAK
I/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 ONTAK was marketed in the U.S. from 1999 to 2014, when it was voluntarily withdrawn from the market.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 (ODD) to I/ONTAK for the treatment of PTCL and CTCL, respectively.
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 systemic 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. Approximately 3,000 new cases are reported in the United States every year, with an estimated 30,000 – 40,000 individuals living with the disease.
About Citius Pharmaceuticals, Inc.
Citius is a late-stage biopharmaceutical company dedicated to the development and commercialization of first-in-class critical care products, with a focus on oncology, anti-infectives in adjunct cancer care, unique prescription products, and stem cell therapies. The Company’s diversified pipeline includes two late-stage product candidates, Mino-Lok®, an antibiotic lock solution for the treatment of patients with catheter-related bloodstream infections (CRBSIs), which is currently enrolling patients in a Phase 3 Pivotal superiority trial, and I/ONTAK (E7777), a novel IL-2R immunotherapy for an initial indication in cutaneous T-cell lymphoma (CTCL), for which a BLA has been submitted. Mino-Lok® was granted Fast Track designation by the U.S. Food and Drug Administration (FDA). I/ONTAK has received orphan drug designation by the FDA for the treatment of CTCL and peripheral T-cell lymphoma (PTCL). In the first half of 2022, Citius initiated a Phase 2b trial for Halo-Lido, a topical formulation for the relief of hemorrhoids. The Company anticipates completing enrollment in the Halo-Lido trial by the end of 2022. For more information, please visit www.citiuspharma.com.
