Revive Therapeutics Announces IRB Approval for Phase 3 Clinical Trial Protocol for Bucillamine in COVID-19

TORONTO, Aug. 31, 2020 (GLOBE NEWSWIRE) -- Revive Therapeutics Ltd. (“Revive” or the “Company”) (CSE: RVV, USA: RVVTF), a specialty life sciences company focused on the research and development of therapeutics for medical needs and rare disorders, is pleased to announce that the Company’s Phase 3 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.

“With the IRB approval of the Phase 3 study protocol for COVID-19, we can recruit U.S. clinical sites efficiently, allowing us to move forward with providing Bucillamine to patients under our IND that was approved by the FDA last month,” said Michael Frank, Revive’s Chief Executive Officer.

An IRB operates under FDA regulations and is an FDA registered constituted group that has been formally designated to review and monitor biomedical research involving human subjects. In accordance with FDA regulations, an IRB has the authority to approve, require modifications (to secure approval), or disapprove research. The purpose of IRB review is to assure, both in advance and by periodic review, that appropriate steps are taken to protect the rights and welfare of humans participating as subjects in the research. To accomplish this purpose, IRBs use a group process to review research protocols and related materials (e.g., informed consent documents and investigator brochures) to ensure the protection of the rights and welfare of human subjects of research.

About the Phase 3 Confirmatory Clinical Study

The Phase 3 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.
