The IDMC also recommends continuation of enrollment in the REGN-COV2 outpatient trial
TARRYTOWN, NY, USA I October 30, 2020 I Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) received today a recommendation from the independent data monitoring committee (IDMC) for the REGN-COV2 antibody cocktail treatment trials for COVID-19 that the current hospitalized patient trial be modified. Specifically, based on a potential safety signal and an unfavorable risk/benefit profile at this time, the IDMC recommends further enrollment of patients requiring high-flow oxygen or mechanical ventilation be placed on hold pending collection and analysis of further data on patients already enrolled. The IDMC also recommends continuing enrollment of hospitalized patients requiring either no or low-flow oxygen as the risk/benefit remains acceptable in these cohorts. Finally, the IDMC recommends continuation of the outpatient trial without modification.
Regeneron remains blinded to the data and is implementing the IDMC recommendations. Regeneron is also informing the U.S. Food and Drug Administration, which is currently evaluating REGN-COV2 for a potential Emergency Use Authorization in mild-to-moderate outpatients at high risk for poor outcomes. Regeneron is also sharing the recommendation with the independent committee monitoring the RECOVERY trial in the UK, which is evaluating REGN-COV2 in hospitalized patients.
About the REGN-COV2 Trial in Hospitalized Patients
The trial is designed to enroll patients in four independently randomized cohorts:
- Cohort 1: patients on low-flow oxygen
- Cohort 1A: patients not requiring oxygen
- Cohort 2: patients on high-flow oxygen
- Cohort 3: patients on mechanical ventilation
REGN-COV2 is a combination of two monoclonal antibodies (REGN10933 and REGN10987) and was designed specifically to block infectivity of SARS-CoV-2, the virus that causes COVID-19.
To develop REGN-COV2, Regeneron scientists evaluated thousands of fully-human antibodies produced by the company's VelocImmune® mice, which have been genetically modified to have a human immune system, as well as antibodies identified from humans who have recovered from COVID-19. The two potent, virus-neutralizing antibodies that form REGN-COV2 bind non-competitively to the critical receptor binding domain of the virus's spike protein, which diminishes the ability of mutant viruses to escape treatment and protects against spike variants that have arisen in the human population, as detailed in Science.
REGN-COV2's development and manufacturing has been funded in part with federal funds from the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the U.S. Department of Health and Human Services under OT number: HHSO100201700020C. Regeneron has partnered with Roche to increase the global supply of REGN-COV2 beginning in 2021. If REGN-COV2 proves safe and effective in clinical trials and regulatory approvals are granted, Regeneron will manufacture and distribute it in the U.S. and Roche will develop, manufacture and distribute it outside the U.S.
