Efficiently Creating Value with Innovative Science

Press Release

Aug 04, 2020

AGOURA HILLS, Calif., Aug. 04, 2020 (GLOBE NEWSWIRE) -- Mateon Therapeutics (OTCQB: MATN), a leading developer of TGF-β therapeutics, will be working together with Abiogenesis to initiate ARTI-19 randomized, controlled, multi-site India clinical study of Artemisinin against COVID-19. This is part of the company’s humanitarian effort to fund the global, multi-country, observational trial to address the pandemic with Artemisinin. Given the known safety profile and the widespread availability of Artemisinin the company anticipates that clinical development of Artemisinin can be accelerated to effectively deal with the current COVID-19 pandemic.

The company is inviting nonprofits such as non-government organizations to participate in this trial if they have the logistics to participate in observational trials and to distribute the Artemisinin in their home countries. The trial is expected to accrue a minimum of 3,000 patients. At present the company is engaged in India, Africa and Latin America.

This study is designed to evaluate the safety, tolerability, and effectiveness of Artemisinin when used in combination with standard of care (SoC) in mild and moderate COVID-19 patients. Artemisinin is an anti-viral agent with demonstrated activity against SARS-CoV-2 in-vitro comparable to remdesivir, however, with higher safety index. By targeting the host protein, TGF-β, Artemisinin avoids resistance mutations which could render vaccine and/or therapeutics against viral protein(s) ineffective.

Pawan Bhusari, CEO, Abiogenesis, stated: “The COVID-19 pandemic is the greatest health challenge for India where the healthcare system is underserved. Abiogenesis is proud to collaborate with Mateon to develop a possible treatment for this virus. The discovery of Artemisinin as a potential anti-viral agent is particularly important since this program has the potential to address the pandemic effectively because it is based on a product that is readily available. We are thrilled to support Mateon in India with our domain expertise in clinical research to potentially develop a treatment that could be instrumental in treating patients with COVID-19.”

About Artemisinin

Artemisinin can target multiple viral threats including COVID-19 by suppressing both viral replication and clinical symptoms that arise from viral infection. Viral replication cannot occur without TGF-β. Artemisinin, purified from a plant Artemisia annua, is able to inhibit TGF-β activity and is able to neutralize SARS-CoV-2 (COVID-19) in vitro at an EC50 of 0.45 ug/ml (Mateon’s test result at Utah State University), and a Safety Index of 140, which is better than remdesivir and chloroquine. The unpurified herb extract has no anti-viral activity. Artemisinin also has been reported to have antiviral activities against hepatitis B and C viruses, human herpes viruses, HIV-1, influenza virus A, and bovine viral diarrhea virus in the low micromolar range. TGF-β surge and cytokine storm cannot occur without TGF-β. Clinical consequences related to the TGF-β surge, including ARDS and cytokine storm, are suppressed by targeting TGF-β with Artemisinin. Indeed, TGF-β knockout mice that are genetically TGF-β deficient, have been shown to be resistant to the influenza virus. In the clinic, Artemisinin exhibits early efficacy signals against COVID-19. To date, 25 effective cases have been reported, with an average time of negative nucleic acid conversion of 4 days, and a negative conversion rate of 10 days after nucleic acid detection reached 96%. No serious adverse reactions were seen. After treatment, the patient's chest image examination showed that the inflammation in the lungs was relieved and the symptoms were significantly improved. Because it targets a host protein- TGF-β that plays a pivotal role in ARDS pathophysiology (and not a virus-intrinsic target), Artemisinin does not promote the development of drug-resistant viral mutations.
