RECOVERY COVID-19 Phase 3 Trial to Evaluate Regeneron's REGN-COV2 Investigational Antibody Cocktail in the UK
One of the world's largest efforts to find effective COVID-19 treatments will evaluate the impact of REGN-COV2 on mortality, hospital stays, and the need for ventilation
"The world urgently needs new medicines to combat COVID-19, and well-designed trials to evaluate new treatment options will quickly help us learn which are most effective," said
REGN-COV2 is the first specifically designed COVID-19 therapy being evaluated by RECOVERY. It was selected in part based on its emerging safety profile in humans, pre-clinical data showing it could protect against viral escape mutations, and prevention and treatment studies in non-human primates showing it reduced the amount of virus and associated damage in the lungs. REGN-COV2 is currently being studied in two Phase 2/3 clinical trials for the treatment of COVID-19 and in a Phase 3 trial for the prevention of COVID-19 in household contacts of infected individuals.
"We are very grateful to the patients who have already taken part in the trial and to those who will participate in this next phase of RECOVERY. We would not be able to find the best treatments without their support and that of the thousands of hospital and research staff who are working with us."
The open-label RECOVERY trial will assess the impact of adding REGN-COV2 to the usual standard-of-care on all-cause mortality 28 days after randomization. Other endpoints include the impact on hospital stay and the need for ventilation. It is anticipated that at least 2,000 patients will be randomly allocated to receive REGN-COV2 plus usual standard-of-care, and results will be compared with at least 2,000 patients who receive standard-of-care on its own. Usual standard-of-care varies by local hospital.
The trial is being coordinated by researchers at the
About the Trial
The RECOVERY trial is conducted by the registered clinical trials units in the
The trial involves many thousands of doctors, nurses, pharmacists, and research administrators at 176 hospitals across the whole of the
The inclusion of convalescent plasma in the RECOVERY trial was announced in June. The trial will compare adding convalescent plasma (plasma taken from patients who have recovered from COVID-19) to usual standard-of-care versus standard-of-care on its own.
REGN-COV2 comprises two monoclonal antibodies (REGN10933 and REGN10987) and was designed specifically by Regeneron scientists to block infectivity of SARS-CoV-2, the virus that causes COVID-19. They 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.
An Independent Data Monitoring Committee is monitoring all Regeneron-led REGN-COV2 Phase 2 and 3 trials, and all trials continue to enroll patients.
REGN-COV2's development and manufacturing has been funded in part by the
Regeneron is accelerating and improving the traditional drug development process through our proprietary VelociSuite technologies, such as VelocImmune®, which uses unique genetically-humanized mice to produce optimized fully-human antibodies and bispecific antibodies, and through ambitious research initiatives such as the Regeneron Genetics Center, which is conducting one of the largest genetics sequencing efforts in the world.
