IRB approves phase III trial of bucillamine in COVID-19.- Revive Therapeutics

Revive Therapeutics announced that the Company’s Phase III clinical trial protocol to evaluate the safety and efficacy of bucillamine in patients with mild-moderate COVID-19 received approval from the independent Institutional Review Board ("IRB") at Advarra, a premier IRB services company in North America. The Phase III confirmatory clinical study titled, “A Multi-Center, Randomized, Double-Blind, Placebo-Controlled Study of Bucillamine in Patients with Mild-Moderate COVID-19”, will enroll up to 1,000 patients that will be randomized 1:1:1 to receive Bucillamine 100 mg three times a day (“TID”), Bucillamine 200 mg TID or placebo TID for up to 14 days. The primary objective is to compare the frequency of hospitalization or death in patients with mild-moderate COVID-19 receiving Bucillamine therapy with those receiving placebo. The primary endpoint is the proportion of patients meeting a composite endpoint of hospitalization or death from the time of the first dose through Day 28 following randomization. Efficacy will be assessed by comparing clinical outcomes (death or hospitalization), disease severity using the 8-category NIAID COVID ordinal scale, supplemental oxygen use, and progression of COVID-19 between patients receiving standard-of-care plus Bucillamine (high dose and/or low dose) and patients receiving standard-of-care plus placebo. Safety will be assessed by reported pre-treatment adverse events and treatment-emergent adverse events (including serious adverse events and adverse events of special interest), laboratory values (hematology and serum chemistry), vital signs (heart rate, respiratory rate, and temperature), and peripheral oxygen saturation. An interim analysis will be performed by an Independent Data and Safety Monitoring Board (“DSMB”) after 210 patients have been treated and followed up for 28 days after randomization. The better performing Bucillamine dose at the interim analysis will be selected and patients will then be randomized 2:1 to the selected Bucillamine dose or placebo. Additional interim analyses will be performed after 400, 600, and 800 patients have reached this same post-treatment timepoint. The independent DSMB will actively monitor interim data for the ongoing safety of patients and will recommend continuation, stopping or changes to the conduct of the study based on the interim analysis reports.
