Study Endpoints

Primary Endpoints

Cohort A: Percentage of Participants Who Have a Symptomatic RT-qPCR Confirmed SARS-CoV-2 Infection (Broad-term) During the EAP
Up to 1 month

Symptomatic SARS-CoV-2 infection (broad-term) is defined as a positive central lab SARS-CoV-2 RT-qPCR result (either NP, nasal or saliva) associated with signs and symptoms with the onset date occurring within 14 days of a positive RT-qPCR during the EAP. Percentage estimated by Logistic Regression.

Cohort B: Percentage of Participants Who Subsequently Develop Signs and Symptoms (Broad-Term) Within 14 Days of a Positive RT-qPCR at Baseline or During the EAP
Up to 14 Days

The percentage of participants was estimated by using the logistic regression model with fixed categorical effects of treatment group, age group (age in years:\>=12 to=50), and region (US vs ex-US).

Cohort A and Cohort B: Number of Participants With at Least One Treatment-emergent Adverse Event (TEAEs) and Severity of TEAEs
Up to 8 months

Secondary Endpoints

Cohort A and Cohort B: Percentage of Participants With High Viral Load in Nasopharyngeal (NP) Swab Samples During the EAP
Up to 1 month
Cohort A: Number of Weeks of Symptomatic RT-qPCR Confirmed SARS-CoV-2 Infection (Broad Term) During the EAP
Up to 1 month
Cohort A and Cohort B: Number of Weeks of High Viral Load in NP Swab Samples During the EAP

Frequently asked questions about REGN10933+ REGN10987

What is REGN10933+REGN10987 used for?

REGN10933+REGN10987 is an investigational combination of two monoclonal antibodies being studied for the prevention and treatment of COVID-19. It has been evaluated in clinical trials for hospitalized adult patients with COVID-19, for prevention of SARS-CoV-2 infection in healthy adults and adolescents who are household contacts of infected individuals, and in healthy adult volunteers.

What does REGN10933+REGN10987 target?

REGN10933+REGN10987 targets the spike (S) protein of SARS-CoV-2, the virus that causes COVID-19. The combination consists of two anti-spike monoclonal antibodies designed to bind to the spike protein and potentially neutralize the virus.

Who makes REGN10933+REGN10987?

REGN10933+REGN10987 is being developed by Regeneron Pharmaceuticals, Inc., a biopharmaceutical company traded on the Nasdaq under the ticker symbol REGN. The company has conducted multiple clinical trials to evaluate the safety and efficacy of this antibody combination for COVID-19.

What phase is REGN10933+REGN10987 in?

REGN10933+REGN10987 has completed Phase 1, Phase 2, and Phase 3 clinical trials. The trials include a Phase 3 study for prevention of SARS-CoV-2 infection in healthy adults and adolescents, and a Phase 1/2/3 study for hospitalized adult patients with COVID-19. All trials are completed.

What clinical trials is REGN10933+REGN10987 in?

REGN10933+REGN10987 has been studied in four completed clinical trials. NCT04426695 evaluated its efficacy in hospitalized adults with COVID-19. NCT04452318 assessed its efficacy for prevention of SARS-CoV-2 infection in healthy household contacts. NCT04519437 studied safety, tolerability, and pharmacokinetics in healthy volunteers. NCT04666441 evaluated virologic efficacy in adult outpatients with SARS-CoV-2 infection.

Is REGN10933+REGN10987 the same as REGN10933 and REGN10987?

REGN10933+REGN10987 is a combination of two monoclonal antibodies, REGN10933 and REGN10987, administered together. The combination is sometimes referred to by the individual component names, but in clinical trials it is studied as a fixed combination product.
