CNS Pharmaceuticals Announces Independent University Research Confirms Active Compound in WP1122 Completely Prevents Coronavirus Replication In Vitro; WP1122 is Subject to Development Agreement with WPD Pharmaceuticals

HOUSTON, April 13, 2020 /PRNewswire/ -- CNS Pharmaceuticals, Inc. (NASDAQ: CNSP) ("CNS" or the "Company"), a biotechnology company specializing in the development of novel treatments for brain tumors, announced that independent research by the University of Frankfurt found 2-deoxy-D-glucose ("2-DG") to reduce replication of SARS-CoV-2, the virus that causes COVID-19, by 100% in in vitro testing.

Researchers at the University of Frankfurt disclosed the findings in their article submitted to NatureResearch on March 11, 2020 (Bojkova, D et al; DOI: 10.21203/rs.3.rs-17218/v1) (https://www.researchsquare.com/article/rs-17218/v1). The authors reported that inhibiting glycolysis with non-toxic concentrations of 2-DG completely prevented SARS-CoV–2 replication in Caco–2 cells.  Glycolysis is a process by which cells convert glucose into energy and infected (host) cells are induced by viruses to dramatically increase their dependence on glycolysis. 2-DG inhibits glycolysis because, although it appears to cells to be glucose, it is in fact a decoy that cannot be converted into energy.

As previously announced, CNS entered into an agreement with WPD Pharmaceuticals Inc. (CSE: WBIO), for the development of several preclinical drug candidates including WP1122. WP1122, which is being tested on a range of viruses including the coronavirus SARS-CoV-2, is a prodrug of the glucose decoy called 2-deoxy-D-glucose, or 2-DG. While the free form of 2-DG is rapidly metabolized and ineffective within minutes of entering the body, WP1122 has a much longer half-life, potentially enabling it to deliver quantities adequate for a therapeutic effect. WPD Pharmaceuticals previously licensed rights to a portfolio of drug candidates, including WP1122, from Moleculin Biotech, Inc. for certain territories.

"We are extremely encouraged by this breakthrough discovery of WP1122's potential efficacy in fighting COVID-19," commented John M. Climaco, CEO of CNS Pharmaceuticals. "We believe these findings represent a significant catalyst and incentive to expedite the development of WP1122. We look forward to working closely with WPD Pharmaceuticals to continue the advancement of the WP1122 program toward a potential life-saving treatment for this deadly disease, the death toll from which is nearly 100,000 lives worldwide this year and climbing every hour."

Under the CNS Agreement, WPD will receive a portion of the development costs from CNS for WP1122 and other drug candidates for antiviral indications, and CNS will receive certain economic rights. WPD received an upfront cash payment of $225,000 and CNS has committed to a milestone payment of $775,000 upon the successful completion of a Phase 2 study. In return for the funding, CNS is entitled to receive 50% of the net sales, less WPD's license costs, of resulting commercial products in WPD's licensed territories, other than Poland. Those territories include 29 countries in Europe and Asia, including Russia.
