ARTIShield ™/ARTIVedaTM- an Ethnobiology Drug

Mateon is pursuing several avenues with respect to the development and commercialization of ARTIShield in the treatment of COVID-19. ARTIShield is Ayurveda - Dvipaantara Damanaka - and is labeled as a capsule containing Artemisia Powder 500mg. It is a demonstration of how Ethnobiology can be used to drive drug development against emerging pandemics.

The classical pharmaceutical regulatory pathways have failed to provide fast-track to treatment and vaccines. Government resources have concentrated on a few candidates most of which have failed. The Ayurvedic medicine route is proving to be an accelerated pathway to deploy a well-known, abundantly available and cost effective Ayurvedic medicine that is safe and being proven in-vitro and large-scale clinical trial to be effective.

ARTIShield /ARTIVeda - Commercialization in India 

Mateon announced that ARTIShield /ARTIVeda has been approved for manufacture and marketing by the Ministry of AYUSH (Ayurveda, Yoga and Naturopathy, Unani, Siddha and Homoeopathy) in India for the treatment of various symptoms including fever and inflammation, which can be associated with COVID-19. ARTIShield is in co-development with Windlas Biotech Pvt. Ltd., Mateon’s commercial partner for India and is designed to be a readily available and cost-effective agent to combat COVID-19. ARTIVeda is the tradename for India and ArtiShieldTM is the tradename for outside of India. Mateon expects sales will commence in India before year end.

ARTI-19 Multi-national Phase IV Trial, Currently in India

Mateon announced the enrollment of its first patient in a Phase IV study ARTI-19, “A Prospective, Randomized, Multi-center, Open label, Interventional Study to Evaluate the Safety and Efficacy of Artemisinin 500 mg capsule in Treatment of Adult Subjects with COVID-19”. This trial will compare the efficacy of oral doses with standard-of-care (SOC) versus SOC alone. This is a global study with India to contribute at least 300 patients to the total aggregate of 3000 patients. We expect preliminary top-line data for ARTI-19 sometime between Q420 and Q121.

About OT-101

OT-101 is an antisense against the host TGF-β protein required for viral replication and its overexpression likely to cause the wide range of clinical symptoms associated with COVID-19 including Kawasaki syndrome (Fatih M. Uckun, Vuong Trieu. Targeting Transforming Growth Factor-beta for Treatment of COVID-19-associated Kawasaki Disease in Children. Clin Res Pediatr 2020; 3(1): 1-3) and acute respiratory distress syndrome (ARDS) (Fatih M. Uckun, Larn Hwang, Vuong Trieu. Selectively targeting TGF-β with Trabedersen/OT-101 in treatment of evolving and mild ARDS in COVID-19. Clin. Invest. (Lond.) 2020; 10(2), 167-176. DOI: 10.4172/ Clinical-Investigation.1000166.).

TGF-β is elevated in COVID-19 (Xiong Y. et al. Transcriptomic characteristics of bronchoalveolar lavage fluid and peripheral blood mononuclear cells in COVID-19 patients. Emerging Microbes & infections 2020; 9:1, 761-770, DOI: 10.1080/22221751.2020.1747363. Agrati C. et al. Expansion of myeloid-derived suppressor cells in patients with severe coronavirus disease (COVID-19). Cell Death & Differentiation 2020; https://doi.org/10.1038/s41418-020-0572-6.).

OT-101 is also being developed as an adjuvant for second generation COVID-19 vaccine. To avoid the two potential issues with 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 sufficiently protective to counter the current pandemic.

The development of OT-101 is important given the failure of other drugs leaving dexamethasone as the only clinically proven effective drug against COVID-19.

About Mateon Therapeutics

Mateon was created by the recent reverse merger with Oncotelic, which became a wholly owned subsidiary of Mateon, thereby creating an immuno-oncology company dedicated to the development of first in class RNA therapeutics as well as small molecule drugs against cancer and infectious diseases. OT-101, the lead immuno-oncology drug candidate of Mateon/Oncotelic, is a first-in-class anti-TGF-βRNA therapeutic that exhibited single agent activity in some relapsed/refractory cancer patients in clinical trial settings. OT-101 also has activity against SARS-CoV-2. Mateon/Oncotelic is seeking to leverage its deep expertise in oncology drug development to improve treatment outcomes and survival of cancer patients with a special emphasis on rare pediatric cancers. Mateon has rare pediatric designation for DIPG (OT-101), melanoma (CA4P), and AML (OXi4503).
