$RVVTF (copy) FRESS DD - A week ago we noticed that Revive is EXPANDING The Bucillamine trial to Canada for CV-19 follow the sign post people this means the drug is doing its thing in the USA phase 3 trial
“We would like to welcome Dr. Moody as a medical and clinical advisor to our team and we look forward to his contributions in our ongoing FDA Phase 3 clinical study as well as expanding our COVID-19 studies in Canada,”

Scientific Rationale for the Investigation of Bucillamine to Treat Infectious Diseases, including COVID-19
Current antiviral interventions for influenza have exhibited modest efficacy, especially in improving mortality in at-risk populations, such as the elderly.1,2 Novel antivirals have been plagued by poor oral bioavailability and lack of efficacy when not delivered early.1 This is because these drugs mostly act to prevent the early processes of virus binding to cells or viral replication.2 Thiols, particularly N-acetylcysteine (NAC), with antioxidant and reducing activity have been investigated as effective therapies that abrogate the potential for influenza to cause severe disease.3,4,5 Restoration of glutathione, the major intracellular thiol antioxidant, is a critical functional activity of NAC.6 Reactive oxygen species (ROS) generation during influenza virus infection aggravate destructive inflammation and programmed death of epithelial cells.7 Studies in human cells and animal models have shown that NAC works to prevent acute lung injury caused by influenza virus infection through inhibition of these ROS-mediated mechanisms.4,7 NAC has been investigated clinically and found to significantly attenuate clinical symptoms associated with influenza infection, especially in elderly at-risk patients.5 While NAC is easily taken up by cells and has low toxicity, clinical efficacy has required long-term and high-dose administration because of modest relative potency, limiting its clinical applicability.
Bucillamine (N-(mercapto-2-methylpropionyl)-l-cysteine), which has a well-known safety profile and is prescribed in the treatment of rheumatoid arthritis in Japan and South Korea for over 30 years, is a cysteine derivative with 2 thiol groups that is 16-fold more potent than NAC as a thiol donor in vivo, giving it vastly superior function in restoring glutathione and therefore greater potential to prevent acute lung injury during influenza infection.8 Bucillamine has also been shown to prevent oxidative and reperfusion injury in heart and liver tissues8 and is highly cell permeable for efficient delivery into cells.8,9 Bucillamine has unrealized potential for the treatment of influenza with both proven safety and proven mechanism of action similar to that of NAC, but with much higher potency, mitigating the previous obstacles to using thiols therapeutically. It is also reasonable to hypothesize that similar processes related to ROS are involved in acute lung injury during nCov-19 infection, justifying the investigation of bucillamine as an intervention for COVID-19.
Revive Therapeutics Announces IRB Approval of US Expanded Access Treatment Program (Compassionate Use) for Bucillamine in COVID-19
The EAP for compassionate use provides physicians with access to Bucillamine under Revive’s existing Investigational New Drug (“IND”) application for COVID-19. According to the FDA, expanded access is a potential pathway for a patient with an immediately life-threatening condition or serious disease or condition to gain access to an investigational medical product for treatment outside of clinical trials when no comparable or satisfactory alternative therapy options are available.
