Item 8.01

Provisional Patent Filing

On August 18, 2020 Oncotelic, Inc. (“Oncotelic”), a wholly-owned subsidiary of Mateon Therapeutics, Inc. (“Mateon” or the “Company”), filed a provisional patent application on the method of use and composition of matter for second generation COVID-19 vaccine leveraging on OT-101 as adjuvant. To avoid the two potential issues wiith 1st generation vaccine against COVID-19, we will be combining the 1st generation COVID-19 DNA vaccine with a TGF-β inhibitor (OT-101) to stimulate a strong immune response while suppressing the IgA class switching that could aggravate the disease through Kawasaki reaction- IgA vasculitis. The company is aggressively pursuing the development of this 2nd generation COVID-19 vaccine expecting that the 1st generation vaccines would not be fully effective and may not be sufficient to counter the current pandemic.

Mateon Therapeutics, Inc., formerly OXiGENE, Inc., is a biopharmaceutical company. The Company is focused on the development of vascular disrupting agents (VDAs) for the treatment of cancer. The Company is engaged in developing two clinical stage investigational drugs: VDAs-CA4P and OXi4503. Its lead compound is CA4P, which is also known as combretastatin A4-phosphate, fosbretabulin tromethamine, fosbretabulin and ZYBRESTAT. VDAs selectively targets the vasculature of cancer tumors and obstructs a tumor’s blood supply without disrupting the blood supply to normal tissues. VDAs are in a class of drugs called vascular targeted therapies (VTTs), which also includes anti-angiogenic agents (AAs). CA4P is a reversible tubulin binding agent that selectively targets the endothelial cells that make up the blood vessel walls in solid tumors. The Company is pursuing the development of a product candidate, OXi4503, which is a dual-mechanism VDA.
