Revive Therapeutics Submits Updated Briefing Package in Support of Upcoming Type C Meeting Granted by FDA for Amended Protocol Agreement of Phase 3 Clinical Study for Bucillamine in the Treatment of COVID-19
Revive Therapeutics Ltd. (OTCQB: RVVTF) has submitted an updated briefing package to the FDA for its Phase 3 clinical trial of bucillamine as a treatment for COVID-19. This submission includes revised primary and efficacy endpoints, following the FDA's agreement on a Type C meeting request. The trial aims to assess bucillamine's impact on clinical symptoms by comparing patients' conditions at baseline and Day 14. The FDA's response is expected by March 7, 2023. Revive is focusing on outpatient management of mild to moderate COVID-19 cases, with bucillamine potentially mitigating disease burden through its anti-inflammatory and antiviral properties.
- Updated FDA briefing package submitted for Phase 3 trial of bucillamine.
- FDA granted Type C meeting request to discuss revised protocol endpoints.
- Proposed primary efficacy endpoint aims to assess symptom improvement by Day 14.
- No specific clinical results or data from the Phase 3 trial have been disclosed.
- The effectiveness of bucillamine compared to placebo remains to be determined.
TORONTO, Jan. 19, 2023 (GLOBE NEWSWIRE) -- Revive Therapeutics Ltd. (“Revive” or the “Company”) (OTCQB: RVVTF) (CSE: RVV) (FRANKFURT: 31R), a specialty life sciences company focused on the research and development of therapeutics for medical needs and rare disorders, announces today that it has submitted the updated briefing package to the U.S. Food & Drug Administration (“FDA”) to include the rationale for the proposed primary and efficacy endpoints for the amended protocol in the treatment of COVID-19 and supporting new information and independent published studies, including the most recent published study, titled “Omicron Spike Protein Is Vulnerable to Reduction.”
As recently reported by the Company, the FDA has granted the Company’s Type C meeting request to obtain agreement on the revised protocol endpoints for the Company’s Phase 3 clinical trial (the “Study”) (NCT04504734) to evaluate the safety and efficacy of bucillamine, an oral drug with anti-inflammatory and antiviral properties, in patients with mild to moderate COVID-19. The goal date for the FDA to provide its written responses is March 7, 2023.
The Company previously submitted to the FDA the Study’s amended protocol with the new primary efficacy endpoint, specifically, assessing the difference in the proportion of participants with improvement in at least two COVID-19 related clinical symptoms on or before Day 14 compared with baseline between bucillamine versus placebo. Additional secondary endpoints are considered, including the time to the polymerase chain reaction resolution, clinical outcome (death or hospitalization), disease severity, supplemental oxygen use, and progression of COVID-19.
Should the FDA agree with the Company’s proposed primary and secondary endpoints or a version that the FDA recommends, the Company will incorporate these endpoints into the amended Study protocol. Once the amended Study protocol is agreed upon, the Data Safety Monitoring Board (“DSMB”) will then review the completed Post-Dose selection data of approximately 500 subjects in the context of the new protocol endpoints. The DSMB may recommend continuing the Study if there is a trend toward achieving statistical significance, halting the Study early due to statistical significance likely not going to be met, or halting the Study early due to positive efficacy showing statistical significance. In the latter case, the Company would request a meeting with the FDA to determine the appropriate next steps toward obtaining potential regulatory approval.
The Company’s proposed new primary efficacy endpoints are due in part to the evolving and current state of COVID-19, where many patients with COVID-19 are either asymptomatic or experience mild to moderate illness and could be managed in the outpatient setting. Patients who would have been at increased risk for progression to severe COVID-19 or require hospitalization during the various variant surges are now being managed less aggressively as outpatients, with close follow-up and monitoring for clinical changes. Based on bucillamine’s proposed mode of action, it is believed that the speed of symptom resolution and reduced viral shedding, if given promptly, could help mitigate the disease burden globally. Thus, the Company believes that comparing the pre-treatment baseline disease to the observed improvement in the severity of clinical symptoms at Day 14 in the enrolled Study population will provide a reasonable estimation of the efficacy of bucillamine on clinically meaningful aspects of the disease. Symptoms such as, but not limited to, fever or chills, cough, shortness of breath or difficulty breathing, heart rate, fatigue, muscle or body aches, headache, loss of taste or smell, sore throat, congestion or runny nose, nausea or vomiting, and diarrhea have clinical relevance.
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.
