Mateon Enters into Merger Agreement with Oncotelic

Forms Late Clinical-Stage Cancer Immunotherapy Company Focusing on TGF-β RNA Therapeutics

SOUTH SAN FRANCISCO, Calif. and AGOURA HILLS, Calif., April 18, 2019 (GLOBE NEWSWIRE) -- Mateon Therapeutics, Inc. (OTCQB:MATN) and Oncotelic Inc., a privately-held, late clinical-stage cancer immunotherapy company, announced today that they have entered into a definitive agreement with respect to a merger, creating a publicly traded immuno-oncology company with a robust pipeline of first in class TGF-β immunotherapies for late stage cancers such as gliomas, pancreatic cancer and melanoma.

/EIN News/ -- “We believe that the merger of Oncotelic and Mateon will create a combined company that can generate shareholder value through a promising pipeline of next generation immunotherapies targeting several significant cancer markets where there is a paucity of therapeutic options and lack of an effective immunotherapy protocol,” said Vuong Trieu, Ph.D., Co-Founder, Chairman and Chief Executive Officer of Oncotelic. “We chose Mateon due to the synergies between the two organizations’ pipelines, including the natural synergy of Mateon’s CA4P necrotic cell death product candidate and Oncotelic’s proprietary self-immunization protocol (SIP) platform, particularly our TGF-β inhibitor OT-101.”

“Our priority has been to continue our mission to help patients and to provide meaningful value to our stockholders," said William D. Schwieterman, M.D., Mateon’s President and Chief Executive Officer. “After a review of their pipeline, and a thorough consideration of potential strategic alternatives, we have concluded that a merger with Oncotelic, which has multiple late clinical-stage product candidates in areas of unmet medical need, offers our best opportunity to create such value. I look forward to completing this merger expeditiously and working with the full Oncotelic team as clinical trial milestones occur in 2019 and beyond.”

SIP® Platform

Oncotelic’s SIP® Platform is based on novel and proprietary sequential treatment of cancers with OT-101, an antisense against TGF-β2 combined sequentially with widely used chemotherapies. This sequential treatment has resulted in many instances in patients’ self-immunization against their own tumors, resulting in robust response and survival.  In some cases, this was curative. The use of OT-101 has lifted the immunosuppression in local tumor environment allowing for effective initial priming of the immune response. The subsequent chemotherapy-released neoantigens have served as a boost to bolster the immune system against the tumors. Judicious placement of immune expanders such as IL-2 and/or checkpoint inhibitors within the immunization protocol is expected to have dramatic impact on survival.

Growing Product Pipeline

Oncotelic is developing OT-101 in combination with chemotherapy for the treatment of gliomas and pancreatic cancers.  Oncotelic plans to initiate several Phase 3 registration trials for OT-101 in multiple cancer indications, including gliomas and pancreatic cancers.

During phase 2 clinical trials in gliomas (Study G004) and pancreatic cancer, melanoma, and colorectal cancers (Study P001), meaningful clinical benefits were observed with favorable safety profiles. These clinical benefits included long term survival as well as tumor reduction. These findings have been presented at recent scientific conferences recently and are available for viewing at www.oncotelic.com.

Merger Terms

In the transaction, Mateon will issue 41,000,033 shares of common stock and 193,713 shares of newly designated Series A preferred stock to Oncotelic shareholders. Each share of Series A preferred stock will be convertible into 1,000 shares of common stock, and will be automatically converted into common stock following stockholder approval of additional authorized shares of common stock or a reverse split. Assuming the conversion of all preferred shares, current Oncotelic stockholders would own 85% of the combined company, and current Mateon stockholders will own 15%.

In addition to their ownership position in the newly combined company, Mateon stockholders of record as of the business day immediately preceding the closing date of the merger will receive a contingent value right (CVR) related to Mateon’s drug candidates OXi4503 and CA4P. CVR holders are entitled to receive 75% of the net proceeds in excess of $0.5 million from a sale of assets relating to these two drug candidates for a four-year period following the merger. The CVRs will not be registered to trade on any stock exchange, and new discoveries related to these drug candidates are not subject to payment obligations under the CVR.

The merger is subject to customary conditions to closing including the approval by Oncotelic’s shareholders.  Approval is expected within one business day, and the merger is expected to close on or about April 22, 2019.

In connection with the merger agreement, the company has entered into a series of bridge financing agreements for the issuance of debentures with a face amount of up to $1.2 million. The first tranche of convertible debentures with a face value of $600,000 is expected to fund shortly following the closing of the merger. A second tranche of convertible debentures, also aggregating $600,000, is available if requested by the company. The debentures will be issued at a discount of 10% and convertible into common stock at a fixed price of $0.10 per share for six months, if not repaid by the company. The company can repay the debentures in accordance with a sliding schedule of premiums over a six month period, after which the debentures are convertible into common stock at a discount to the stock price at the time of conversion.

  • Chief Executive Officer - Vuong Trieu, PhD, Co-Founder, Chairman, CEO of Oncotelic
  • Chief Medical Officer - Fatih Uckun, MD, PhD

About Oncotelic, Inc.

Oncotelic is a privately held cancer immunotherapy company dedicated to the development of first in class in self-immunization protocol (SIP©) as a durable cure for difficult to treat cancers. This therapeutic cancer vaccine has broad-spectrum applicability for multiple cancer types and does not require extraction of the tumor and isolation of the antigen for immunization- a lengthy/laborious process with limited clinical effectiveness. It showed promising clinical activity in phase 2 trials for the treatment of gliomas and pancreatic cancers. The company aims to translate its unique insights spanning more than three decades with original work at Genetic Therapy Inc using adenovirus as RNA therapeutics to the current deployment of antisense as RNA therapeutics for diseases caused by TGF-beta overexpression including cancer. The founding team of Oncotelic was part of the team who developed Abraxane® as chemotherapeutic agents for breast, lung, melanoma, and pancreatic cancer. Abraxane® was approved in 2005 and has $1B in sales annually.  The team later on led the development and commercialization of Cynviloq®, a next-generation Abraxane.  Cynviloq® was acquired by NantPharma. Oncotelic intends to leverage its deep expertise in oncology and RNA therapeutic drug development to promote the eventual cure and eradication of cancers.
