MATEON ANNOUNCES POSITIVE INTERIM RESULTS FROM ARTI-19 CLINICAL TRIAL EVALUATING COVID-19 THERAPEUTIC


AGOURA HILLS, California, Jan. 13, 2021 (GLOBE NEWSWIRE) -- Mateon Therapeutics, Inc. (OTCQB: MATN) (“Mateon”), a leading developer of TGF-β therapeutics for oncology and COVID-19, reported positive interim results from its ARTI-19 clinical trial evaluating ARTIVedaTM against COVID-19.

“These interim results suggest that ARTIVeda is a well-tolerated and effective treatment for COVID-19 that produces a faster recovery time when compared to Standard of Care alone,” said Dr. Vuong Trieu, Chairman and CEO of Mateon.

ARTIVeda is Mateon’s lead Ayurvedic drug against COVID-19 in India and is being developed by Mateon in partnership with Windlas Biotech Private Limited (India). ARTI-19 India is being conducted by Windlas as part of Mateon’s global effort to deploy ARTIVeda across India, Africa, and Latin America. These interim results are based on 60 randomized patients (out of 114 randomized to date) across 3 sites in India:

  • No adverse events were reported that required discontinuation of treatment
  • A majority of the 60 patients who received ARTIVeda plus Standard of Care (SOC) recovered faster than those who received SOC alone, with SOC defined as treatment with Remdesivir, Ivermectin, Dexamethasone, Heparin, as well as Paracetamol, B complex, Vitamin-C, and Zinc.
  • The median time to asymptomatic WHO scale of 1 was 5 days for ARTIVeda plus SOC as compared to 14 days for SOC alone. The differences were statistically significant meaning unlikely to happen by chance.
  • The trend was more pronounced with higher initial disease status. Log rank statistics: WHO-scale 2,3,4: p= 0.0369 /RR = 1.476 (0.8957-2.433), WHO-scale 3,4: p= 0.026/ RR = 1.581 (0.9094-2.747), WHO-scale 4: p= 0.0043/ RR = 2.038 (0.9961-4.168). RR = rate ratio for recovery.

The ARTI-19 India trial is slated to complete enrollment of 120 randomized patients by end of January, 2021, with final data available 6-8 weeks thereafter. Upon completion of the trial, it is Mateon’s objective to file for Emergency Use Authorization (EUA) with regulatory authorities around the world, including India, the United States, and the United Kingdom; discussions regarding EUA with several of these authorities have commenced.

ARTIVeda combines Mateon’s TGF beta platform and ethnobiology drug knowledge for rapid development and deployment of the drug product against the COVID-19 pandemic. More detailed information about the trial, including more comprehensive data, will be available in a forthcoming report.

Windlas is a prominent global CDMO (contract development and manufacturing organization) that also manufactures, markets and distributes its own branded products (allopathic, nutraceutical and AYUSH formulations) through its “affordable generics platform” spanning over 950 wholesalers across India. Windlas products are sold in markets across the globe in India, USA, Sri Lanka, Vietnam, Thailand, Myanmar, and Africa.

Saran Saund, Chief Business Officer and GM of the AI division of Mateon, commented, “Now that we have clinical support for the efficacy of ARTIVedaTM against COVID-19, we will look to deploying the drug across multiple countries in an effort to stop this pandemic.”

Dr. Suhas Kshirsagar, Director of the Ayurvedic Healing and Integrative Wellness Clinic and advisor to Mateon on ARTIVeda commented, “This positive interim analysis of ARTI-19 further supports our integration of Ayurvedic healing and modern clinical sciences for rapid response to emerging pandemic. I look forward to working with the team at Mateon and Windlas for the successful deployment of this drug. The product, ARTIVedaTM, is a formulated plant extract of the indigenous plant Artemisia, known in Sanskrit texts as Damanaka. ARTIVedaTM is the first Ayurvedic drug against COVID-19 through TGF-β inhibition.”

Dr. Wanjun Chen, Chief of the Mucosal Immunology Section at NIDCR (USA) and advisor to Mateon on this trial commented, “The clinical effectiveness of ARTIVedaTM - a known TGF-beta inhibitor- against COVID-19, validated our concept reported previously by Chen et al., 2020/ Uckun et al. 2020. As it stands ARTIVedaTM with its inhibition of TGF-beta has the potential of treating COVID-19 through inhibition of myriads of pathological responses to the TGF-beta surge due to COVID-19.”

About ARTIVedaTM

The product, ARTIVedaTM, is a formulated plant extract of the indigenous plant Artemisia, known in Sanskrit texts as Damanaka. ARTIVedaTM is the first Ayurvedic drug against COVID-19 through TGF-β inhibition. ARTIVedaTM is expected to be effective through the entire infection cycle. The active component of ARTIVedaTM has been identified as artemisinin. Through proprietary GMP quality extraction and manufacturing processes, the Artemisia extract was rendered active against SARS-CoV-2 with robust Safety Index (SI) greater than 100 (ratio of nonspecific cell kill versus viral kill). Other extracts have SI <10. Testing was performed at the US NIAID core viral laboratory. The product is protected by a patent portfolio of over 15 international patents by Mateon’s R&D. The mechanism of action against COVID-19 has been confirmed in 5 key peer reviewed international scientific/medical publications. ARTIVedaTM is designed to target multiple viral threats including COVID-19 by suppressing both viral replication and clinical symptoms that arise from viral infection. A phase IV trial looking at ARTIVedaTM in COVID-19 is ongoing in India and globally. We are looking to leverage ex-US data for the commercialization of the product in the US. We are expecting the product to be a cost effective prophylactic suitable for global deployment.
