Cocrystal Pharma Announces the Publication by Collaborators of Positive Data Demonstrating Potent In Vitro Inhibition Against Coronavirus in Science Translational Medicine Journal

– Cocrystal has two exclusive licenses for the coronavirus protease inhibitors described in the publication –

– Cocrystal is currently further conducting preclinical studies of these coronavirus protease inhibitors (3CL) –

BOTHELL, WA, Aug. 04, 2020 (GLOBE NEWSWIRE) -- (NASDAQ: COCP), (“Cocrystal” or the “Company”), a clinical stage biotechnology company discovering and developing novel antiviral therapeutics, today announced the publication of preclinical animal studies of coronavirus antiviral compounds in the renowned medical journal, .

The manuscript titled, “,” was published online in the 3 August 2020 Science Translational Medicine Journal. Authors of the published manuscript were Athri D. Rathnayake, Jian Zheng, Yunjeong Kim, Krishani Dinali Perera, Samantha Mackin, David Meyerholz, Maithri M. Kashipathy, Kevin P. Battaile, Scott Lovell, Stanley Perlman, William C. Groutas, Kyeong-Ok Chang.

Data presented in the publication is included in the Company’s two exclusive license agreements with Kansas State University Research Foundation (“KSURF”) for .

“Our license agreement with KSURF has continued to exhibit the potential and broad utility of our platform to address the SARS-CoV-2 virus responsible for the COVID-19 worldwide pandemic. To have this compelling data included in the prestigious publication, Science Translational Medicine, is a testament to the potential of these inhibitors to treat COVID-19. The publication supports the quality and importance of the work performed by the group of co-authors,” commented Dr. Gary Wilcox, Chairman and Chief Executive Officer of Cocrystal.

Under the license agreements with KSURF, Cocrystal has been granted an exclusive, royalty-bearing right and license to certain antiviral compounds for humans and small molecule therapeutic inhibitors against coronaviruses, picornaviruses and caliciviruses covered by patent rights controlled by KSURF. Cocrystal intends to continue development of these antiviral compounds for coronavirus. These licenses significantly expand and further advance the Company's COVID-19 program by providing more targeted and potent compounds.

“We are incredibly enthusiastic with the positive preclinical data and the solid foundation we believe these inhibitors provide for advancing development of SARS-CoV-2 treatment,” added Dr. Sam Lee, President of Cocrystal. “The potent activity and the effectiveness of the mechanism of action demonstrated by these coronavirus protease inhibitors is very encouraging. Of utmost interest was the activity seen from a select number of compounds in the study series which were shown to be effective in vitro against SARS-CoV-2. In addition, we continue applying our proprietary platform technology to further optimize properties of lead molecules and are also exploring multiple routes of administration of these COVID-19 antivirals. These findings bolster our belief in the broad-spectrum capabilities and demonstrated proof-of-concept therapeutic efficacy of these inhibitors against human and animal coronaviruses.”

Cocrystal initiated its preclinical studies of COVID-19 inhibitors received from KSURF during Q2 2020. The Company has also recently identified additional inhibitors using its proprietary platform technology and anticipates the selection of its lead preclinical molecule by year end.

About Coronavirus Disease 2019 (COVID-19)

COVID-19 is caused by a coronavirus called SARS-CoV-2. Coronaviruses are a large family of viruses that are common in people and many different species of animals, including camels, cattle, cats, and bats. Rarely, animal coronaviruses can infect people and then spread between people. This occurred with MERS-CoV and SARS-CoV, and now with the virus that causes COVID-19.

The virus that causes COVID-19 is thought to spread mainly from person to person, mainly through respiratory droplets produced when an infected person coughs or sneezes. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Spread is more likely when people are in close contact with one another (within about 6 feet).

COVID-19 seems to be spreading easily and sustainably in the community (“community spread”) in many affected geographic areas. Community spread means people have been infected with the virus in an area, including some who are not sure how or where they became infected.
