Submission of Biological License Application (BLA) planned for the second half of 2022
CRANFORD, NJ , July 12, 2022 /PRNewswire/ — Citius Pharmaceuticals, Inc. (“Citius” or the “Company”) (Nasdaq: CTXR), a late-stage biopharmaceutical company developing and commercializing first-class critical care products, today announced Today that the Company held a pre-BLA Type B meeting with the U.S. Food and Drug Administration (FDA) to discuss I/ONTAK (denileukin diftitox), an IL-2-diphtheria toxin fusion protein designed for the treatment of patients with persistent or recurrent cutaneous T-cell lymphoma (CTL). I/ONTAK is a purified and more bioactive formulation of ONTAK previously approved by the FDA®. The pre-BLA meeting was held with representatives from the FDA’s Center for Drug Evaluation and Research (CDER).
The purpose of the pre-BLA meeting with the FDA was to discuss the content and acceptability of the company’s planned BLA for I/ONTAK. The briefing document provided to the FDA included a review of clinical and non-clinical studies and minutes of previous meetings with the FDA.
“We appreciate the continued guidance from the FDA on the path to developing a more purified formulation of ONTAK. Based on feedback from the FDA pre-BLA meeting, we intend to move forward. forward with our planned BLA submission for I/ONTAK in the second half of 2022. We look forward to our continued engagement with the FDA as we advance this program to provide CTCL patients with a potential new treatment option,” said declared Leonard MazurChairman and CEO of Citius.
I/ONTAK is a recombinant fusion protein that combines the interleukin-2 (IL-2) receptor binding domain with diphtheria toxin fragments. The agent binds specifically to IL-2 receptors on the cell surface, causing inhibition of protein synthesis by diphtheria toxin fragments that have entered the cells. I/ONTAK, a purified version of the denileukin diftitox, is a reformulation of the previously FDA-approved oncology treatment ONTAK. ONTAK was marketed in the United States from 1999 until 2014, when it was voluntarily withdrawn from the market. Manufacturing improvements have resulted in a new formulation, which retains the same amino acid sequence but features improved purity and bioactivity. The new formulation received regulatory approval in Japan for the treatment of CTCL and PTCL. In 2011 and 2013, the FDA granted Orphan Drug Designation (ODD) to I/ONTAK for the treatment of PTCL and CTCL, respectively, making it potentially eligible for seven years of market exclusivity after approval for each indication.
About cutaneous T-cell lymphoma
Cutaneous T-cell lymphoma is a type of cutaneous non-Hodgkin’s lymphoma (NHL) that comes in various 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) represent the majority of cases of CTCL. Depending on the type of CTCL, the disease can progress slowly and can take from several years to more than ten years to potentially reach the tumor stage. However, once the disease reaches this stage, the cancer is highly malignant and can spread to lymph nodes and internal organs, resulting in a poor prognosis. Given the duration of the disease, patients typically use multiple systemic agents to control disease progression. CTCL affects men twice as often as women and is usually first diagnosed in patients between the ages of 50 and 60. Other than allogeneic stem cell transplantation, for which only a small fraction of patients are eligible, there is currently no cure for advanced CTCL. About 3,000 new cases are reported in United States each year, with around 30,000 to 40,000 people living with the disease.
