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"


"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"

An interim analysis will be performed by an Independent Data and Safety Monitoring Board ("DSMB"

The Company is not making any express or implied claims that its product has the ability to eliminate or cure COVID-19 (SARS-2 Coronavirus) at this time.
Scientific Rationale of Bucillamine for COVID-19
Preclinical and clinical studies have demonstrated that reactive oxygen species contribute to the destruction and programmed cell death of pulmonary epithelial cells.1 N-acetyl-cysteine (NAC) has been shown to significantly attenuate clinical symptoms in respiratory viral infections in animals and humans, primarily via donation of thiols to increase antioxidant activity of cellular glutathione2,3,4,5. Bucillamine (N-(mercapto-2-methylpropionyl)-l-cysteine) has a well-known safety profile and is prescribed in the treatment of rheumatoid arthritis in Japan and South Korea for over 30 years. Bucillamine, a cysteine derivative with two thiol groups, has been shown to be 16 times more potent as a thiol donor in vivo than NAC 6. The drug is non-toxic with high cellular permeability. The basis of the clinical study will analyze if Bucillamine has the potential, via increasing glutathione activity and other anti-inflammatory activity, to lessen the destructive consequences of SARS-CoV2 infection in the lungs and attenuate the clinical course of COVID-19.
