• Size of ongoing Phase 2 trial of merimepodib in combination with remdesivir increased from 40 to 80 subjects, with focus on hospitalized patients requiring non-invasive ventilation/high flow oxygen devices
• Added 2 new Principal Investigators for the ongoing Phase 2 trial expanding the total number of locations to 10
• Contract Manufacturing Organization (CMO) appointed to manufacture Phase 3 supplies of merimepodib oral solution
• Merimepodib monotherapy trial to be conducted in the outpatient setting after current combination trial completes

BioSig Technologies, Inc. (Nasdaq: BSGM) (“BioSig” or the “Company”) and its majority owned subsidiary, ViralClear Pharmaceuticals, Inc.  (ViralClear), today conducted an investor update call on Viral Clear’s merimepodib drug development program for the treatment of COVID-19.

The size of the ongoing randomized, double-blind, placebo-controlled Phase 2 trial of merimepodib in combination with remdesivir is being increased from 40 to 80 subjects.  When the trial was first initiated, it was thought that COVID-19 patients with National Institute of Allergy and Infectious Disease (NIAID) 8-point ordinal scores of 3 and 4 (i.e., hospitalized patients who require non-invasive ventilation and patients who require high flow oxygen devices and supplemental oxygen, respectively) would have similar outcomes in terms of their disease.  However, based on a review of blinded data from the ongoing trial, subjects with scores of 3 and 4 are showing distinct differences.  All subjects who were admitted with a score of 4 have had an uneventful course of disease and were rapidly discharged from the hospital due to improvement in clinical condition.  The subjects who were admitted with a score of 3 fared differently: one group of subjects improved and were discharged from the hospital and are doing well at long-term follow-up, while others have not improved. 

Based on the above and the small numbers of subjects in each NIAID group, ViralClear decided to increase the enrollment in the current study to 80 subjects, with a focus on subjects with an NIAID score of 3 at entry.  The decision to increase the subject number in the trial was also based on advice from industry experts and discussions with government agencies and non-governmental organizations.  Once additional subjects are enrolled and further clinical data is obtained, the team will discuss with the FDA the appropriate size for a Phase 3 trial. 

Two additional Principal Investigators were added to the ongoing Phase 2 trial to improve the enrollment rate, increasing the total number of locations to 10.   

ViralClear has contracted with a US-based Contract Manufacturing Organization (CMO) to manufacture the registration stability batches [required for the New Drug Application (NDA) filing] of the merimepodib oral solutions (drug product) that will also serve as clinical trial supplies for the Phase 3 trial.  In July 2020, Viralclear previously announced an agreement with another US-based CMO, AMRI, to produce the registration stability batches of the merimepodib (active pharmaceutical ingredient).

The merimepodib monotherapy trial to be conducted in the outpatient setting will be initiated after the completion of the current Phase 2 combination trial.  The Emergency Use Authorizations (EUAs) for remdesivir and convalescent plasma, as well as the increasing use of dexamethasone as a standard of care in hospitalized COVID-19 patients, has precluded an evaluation of merimepodib monotherapy in this setting (i.e., hospitalized patients).

About Merimepodib and ViralClear
BioSig’s Technologies, Inc (Nasdaq: BSGM) 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.
