TENK TenX Keane Acquisition

Citius Pharmaceuticals, Inc. (“Citius Pharma” or the “Company”) (Nasdaq: CTXR), a biopharmaceutical company developing and commercializing first-in-class critical care products, and TenX Keane Acquisition (“TenX”) (NASDAQ: TENKU), a publicly traded special purpose acquisition company (SPAC), today announced that they have entered into a definitive agreement, dated October 23, 2023, for a proposed merger of TenX and Citius Pharma’s wholly owned oncology subsidiary that will continue as a public company listed on the Nasdaq exchange. The newly combined public company will be named Citius Oncology, Inc. (“Citius Oncology”). Upon closing, pursuant to the terms of the merger agreement, Citius Pharma would receive 67.5 million shares in Citius Oncology at $10 per share and retain majority ownership of approximately 90%. The transaction has been approved by the Board of Directors of both companies and is expected to close in the first half of 2024.

CITIUS ONCOLOGY OVERVIEW

Citius Oncology will serve as a platform to develop and commercialize novel targeted oncology therapies. The company is seeking approval from the U.S. Food and Drug Administration (FDA) of LYMPHIR for an orphan indication in the treatment of persistent or recurrent cutaneous T-cell lymphoma (CTCL), a rare form of non-Hodgkin lymphoma. Management estimates the initial market for LYMPHIR currently exceeds $400 million, is growing and is underserved by existing therapies. If approved, LYMPHIR would be unique as the only IL-2 receptor targeted CTCL therapy, offering a novel option to patients cycling through multiple treatments. 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.

Preparations are underway for a Biologics License Application (BLA) resubmission in early 2024. If approved, LYMPHIR could be commercially available as early as the second half of 2024 for the treatment of CTCL. 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.

The transaction is expected to provide Citius Oncology with improved access to the public equity markets and thereby facilitate the commercialization of LYMPHIR and position the company to explore additional value creating opportunities more fully.

CITIUS PHARMA AND TENX COMMENTS

“We believe this transaction will allow us to unlock the value of LYMPHIR, and solidly position Citius Pharma to advance our diversified pipeline. This transaction will enable Citius Oncology, with access to the broader capital markets, to better support the successful commercialization of LYMPHIR, if approved, and explore additional potential targeted oncology therapies. Our majority ownership position and shared services agreement ensures that the Citius Pharma management team will remain fully engaged with the development and commercialization efforts at Citius Oncology. As previously announced, the Company is in the process of formulating a plan of distribution of a portion of the shares of Citius Oncology to its shareholders. At Citius Pharma, we intend to focus on completing the Mino-Lok trial and continuing to evaluate next steps with our Halo-Lido program,” stated Leonard Mazur, Chairman and CEO of Citius Pharma.

“We are very pleased to announce the proposed merger with Citius Oncology,” said Mr. Xiaofeng Yuan, Chairman and CEO of TenX. “After undertaking a comprehensive process with external advisors to explore and evaluate numerous potential business combination targets, our board and management team believe that this transaction with Citius Oncology represents the best opportunity to create substantial value for our stockholders. This business combination, if consummated, will result in TenX investors owning an equity stake in a company that is focused on developing and commercializing LYMPHIR to improve the lives of patients with CTCL and additional potential upside from combinations with other drugs as immuno-oncology therapies with even larger addressable markets. We are thrilled to support Citius Oncology at an inflection point in its development and to provide an avenue for Citius to expeditiously meet its development milestones.”

THE PROPOSED MERGER AGREEMENT

Pursuant to the proposed agreement, TenX will acquire Citius Pharma’s wholly owned subsidiary via a merger, with the newly combined publicly traded company to be named Citius Oncology, Inc. In the transaction, all shares of Citius Pharma’s wholly owned subsidiary would be converted into the right to receive common stock of Citius Oncology. As a result, upon closing, Citius Pharma would receive 67.5 million shares of common stock of Citius Oncology which, at an implied value of $10.00 per share, would be $675 million in equity of Citius Oncology, before fees and expenses. As part of the transaction, Citius Pharma will contribute $10 million in cash to Citius Oncology. An additional 12.75 million existing options will be assumed by Citius Oncology.

At closing, any cash remaining in TenX’s trust account along with the cash provided by Citius Pharma will be contributed to Citius Oncology to support ongoing operations and planned commercialization efforts. References to available cash from the TenX trust account and retained transaction proceeds are subject to any redemptions by the public stockholders of TenX and payment of transaction fees and expenses.

Upon closing, Citius Oncology will operate under a shared services agreement with Citius Pharma, with fees payable quarterly to 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.

The transaction, which has been unanimously approved by both Boards of Directors of Citius Pharma and TenX, is subject to approval by stockholders of TenX and other customary closing conditions. Citius Pharma, as the sole holder of Citius Oncology common stock, has approved the transaction. The proposed business combination is expected to be completed in the first half of 2024.

About Citius Oncology, Inc.

Citius Oncology is a late-stage pharmaceutical company focused on developing and commercializing targeted oncology therapies. Its strategy centers on achieving a market leading position by advancing innovative therapies with reduced development and clinical risks, and leveraging competitive advantages supported by intellectual property and regulatory exclusivity protection. This includes new formulations of previously approved drugs with substantial existing safety and efficacy data or expanded indications for approved therapies.

Citius Oncology’s lead product candidate is LYMPHIR, an engineered IL-2 diphtheria toxin fusion protein, for the treatment of patients with persistent or recurrent CTCL, a rare form of non-Hodgkin lymphoma. Management believes the market for LYMPHIR for CTCL, estimated to exceed $400 million, is attractive, growing and underserved by existing treatments. On July 28, 2023, the FDA issued a complete response letter (CRL) in response to the LYMPHIR BLA. The FDA is requiring enhanced product testing and additional controls agreed to with the FDA during the market application review. There were no concerns relating to the safety and efficacy of the clinical data package submitted with the BLA, or the proposed prescribing information. In September 2023, Citius Pharma announced that the FDA has agreed with the plans to address the requirements outlined in the CRL. This guidance has clarified the path forward in completing the necessary activities to support the resubmission of the BLA for LYMPHIR. The BLA resubmission is anticipated in early 2024.

Citius Oncology was founded in August 2021 as Citius Acquisition Corp., a Delaware corporation and wholly owned subsidiary of Citius Pharma and began operations in April 2022. The corporate name was changed to Citius Oncology, Inc. in May 2023.
