SORRENTO THERAPEUTICS AND VIRALCLEAR ENTER INTO AGREEMENT TO EXPLORE THE COMBINATION OF ANTIBODY AND ANTIVIRAL ASSETS AGAINST COVID-19

Westport, CT, Sept. 30, 2020 (GLOBE NEWSWIRE) --

• Sorrento to initiate testing with a selection of its agents in combination with ViralClear’s anti-viral compound for possible synergistic anti-viral effect against SARS-CoV-2 in the preclinical model of Golden Syrian hamster.
  
• ViralClear to contribute its oral antiviral merimepodib (IMPDH inhibitor) which is currently in a Phase 2 trial in combination with remdesivir to treat COVID-19.
• Sorrento to initially make available STI-1400 neutralizing antibody candidate for testing.
  

ViralClear Pharmaceuticals, Inc. (Nasdaq BSGM) and Sorrento Therapeutics, Inc. (Nasdaq: SRNE, “Sorrento”) announced the companies are exploring the synergistic potential of small molecules and antibodies combination therapies against COVID-19.

In general, multi-modal approaches are considered the most likely to succeed anti-viral strategies. Even with highly effective stand-alone therapies, a synergistic combination can be pursued to help reduce the effective dose needed of each individual agent and aim to ensure maximum effect.

The agreement between ViralClear Pharmaceuticals, Inc. (Parent company BioSig Technologies, Inc. Nasdaq: BSGM), and Sorrento Therapeutics will allow for testing of merimepodib with neutralizing antibodies in the Golden Syrian hamster model of COVID-19.

The study will look for synergy at the effective doses between the two drugs already in human clinical trials and will try to specifically demonstrate that the combined benefits in strengthening and accelerating viral clearance exceed what each drug could deliver by itself.

Pending the outcome of these studies, the results might be presented to the FDA to support the initiation of a human clinical trial of the drug combination.

About ViralClear Pharmaceuticals and Merimepodib
BioSig’s Technologies, Inc (Nasdaq: BSGM  www.biosig.com) subsidiary, ViralClear Pharmaceuticals, Inc. (ViralClear), is seeking to develop a novel pharmaceutical called merimepodib to treat patients with COVID-19. Merimepodib is intended to be orally administered, and has demonstrated broad-spectrum in vitro antiviral activity, including strong activity against SARS-CoV-2 in cell cultures. Merimepodib was previously in development as a treatment for chronic hepatitis C and psoriasis by Vertex Pharmaceuticals Incorporated (Vertex), with 12 clinical trials (7 in phase 1 and 5 in phase 2) with over 400 subjects and patients and an extensive preclinical safety package was completed. A manuscript titled, “The IMPDH inhibitor merimepodib provided in combination with the adenosine analogue Remdesivir reduces SARS-CoV-2 replication to undetectable levels in vitro”, was submitted to an online peer-reviewed life sciences journal. This manuscript is authored by Natalya Bukreyeva, Rachel A. Sattler, Emily K. Mantlo, John T. Manning, Cheng Huang and Slobodan Paessler of the UTMB Galveston National Laboratory and Dr. Jerome Zeldis of ViralClear as a corresponding author. This article highlights pre-clinical data generated under contract with Galveston National Laboratory at The University of Texas Medical Branch.
