The results from this research partnership, if promising, will determine further studies to facilitate FDA and Health Canada approvals for the use of Bucillamine in nerve agents or organophosphate pesticide poisoning. Also, the Company may explore the potential of Bucillamine for traumatic brain injury caused by concussive or explosive forces.

The research project is expected to be completed by June 2024.

Long COVID

The CDC estimates that 7.5 percent of U.S. adults have long COVID symptoms¹. David Cutler, PhD, a professor of economics at Harvard University, estimates in a recent research disclosure that the total economic cost of long COVID could be as much as $3.7 trillion².

Currently, the Company is exploring the use of Bucillamine as a potential treatment for long COVID. The Company is advancing the clinical development of Bucillamine by leveraging the published research and data from its previous Phase 3 clinical trial (the “Study”) in preparing a regulatory and clinical package that includes a proposed Phase 2 clinical study for long COVID to present to the FDA and international health regulatory authorities.

The Phase 2 study protocol has been completed, and the Company is preparing its submission to the FDA. It expects to submit it by the end of March 2024. The proposed Phase 2 clinical study is expected to be approved by the FDA in Q2-2024.

As a background, on July 6, 2023, the Company announced the results of its Study evaluating the safety and efficacy of oral Bucillamine in patients with mild to moderate COVID-19. Under the Study’s primary endpoint, the proportion of patients meeting a composite endpoint of hospitalization or death from time of first dose through Day 28 following randomization, there were no deaths and four hospitalizations, of which three were from the placebo arm and one from the Bucillamine low dose group (300mg/day). No hospitalizations occurred in the Bucillamine large dose group (600mg/day). The Company evaluated certain Study endpoints, including the COVID-19 clinical symptoms data (i.e. cough, fever, heart rate, and oxygen saturation). Based on preliminary analyses, the data demonstrated that for patients with oxygen saturation <96% at baseline, Bucillamine had a 29.1% improvement over placebo in time to normal oxygen saturation (SpO2). Additional analyses of the Study data may suggest Bucillamine’s potential for long COVID.
