Citius Pharmaceuticals, Inc. holds approximately 90% of publicly traded Citius Oncology, Inc.

Shares of Citius Oncology, Inc. anticipated to begin trading on Nasdaq under the ticker "CTOR" on August 13, 2024

CRANFORD, N.J., Aug. 12, 2024 /PRNewswire/ -- Citius Pharmaceuticals, Inc. ("Citius Pharma" 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 it has completed the previously announced merger of its oncology subsidiary with TenX Keane Acquisition ("TenX") (Nasdaq: TENK), a publicly traded special purpose acquisition company. The combined company will operate as Citius Oncology, Inc. ("Citius Oncology") and is expected to begin trading on August 13, 2024 on the Nasdaq stock exchange under the ticker symbol CTOR.

"This transaction is a significant milestone, providing us greater financial and strategic flexibility to advance our late-stage assets. We believe a publicly traded Citius Oncology offers a unique pure play investment opportunity and is better positioned to unlock the value of LYMPHIR, which was approved by the FDA last week. With this transaction, we look forward to launching LYMPHIR, facilitating future growth initiatives, and exploring additional potential oncology assets. It is our intention to distribute of a portion of our shares of Citius Oncology to Citius Pharma shareholders in the future," stated Leonard Mazur, Chairman and CEO of Citius Pharma and Citius Oncology.

"This transaction also enables Citius Pharma to focus on growing and unlocking the value of other assets in its portfolio, including our novel Mino-Lok antibiotic lock solution which recently achieved primary and secondary endpoints in a Phase 3 Trial and is now another step closer to entering a $1.8 billion market," added Mazur.

As it has in the past, Citius Oncology will operate under a shared services agreement with Citius Pharma for the services of several key members of the Citius Pharma team, led by Leonard Mazur, Chief Executive Officer, Jaime Bartushak, Chief Financial Officer and Dr. Myron Czuczman, Chief Medical Officer. Myron Holubiak will serve as Executive Vice Chairman of the Citius Oncology Board of Directors.

About Citius Oncology, Inc.

Citius Oncology will serve as a platform to develop and commercialize novel targeted oncology therapies. In August 2024, its primary asset, LYMPHIR, was approved by the FDA for the treatment of adults with relapsed or refractory CTCL who had had at least one prior systemic therapy. Management estimates the initial market for LYMPHIR currently exceeds $400 million, is growing, and is underserved by existing therapies. Robust intellectual property protections that span orphan drug designation, complex technology, trade secrets and pending patents for immuno-oncology use as a combination therapy with checkpoint inhibitors would further support Citius Oncology's competitive positioning. Citius Oncology is a publicly traded subsidiary of Citius Pharmaceuticals. For more information, please visit

About LYMPHIR (denileukin diftitox-cxdl)

LYMPHIR is a specially engineered IL-2- diphtheria toxin fusion protein made using recombinant DNA technology. It works by targeting cells that have IL-2 receptors with a toxin derived from diphtheria bacteria. Once inside the cell, this toxin stops the cell from making proteins, which leads to cell death. LYMPHIR has two main effects. It directly kills tumor cells by binding to the IL-2 receptors and internalizing the diphtheria toxin directly into the tumor cells, causing them to die. Additionally, it boosts the body's immune response by reducing the number of regulatory T-cells (Tregs) that suppress the immune system, thereby enhancing the body's ability to fight the tumor. LYMPHIR is unique as the only IL-2 receptor targeted CTCL therapy, offering a novel option to patients cycling through multiple treatments.

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 Pharma acquired an exclusive license with rights to develop and commercialize LYMPHIR in all markets except for Japan and certain parts of Asia. In August 2024, LYMPHIR was approved by the FDA for the treatment of adults with relapsed or refractory CTCL who had had at least one prior systemic therapy.

Additional value-creating opportunities in larger markets include potential indications in peripheral T-cell lymphoma or as a combination therapy with CAR-T and PD-1 inhibitors, and in markets outside the U.S. Currently, two investigator-initiated trials are underway to explore LYMPHIR's potential as an immuno-oncology combination therapy.
