Study Endpoints

Primary Endpoints

Percent Change From Baseline in CRP Levels at Day 4 in Participants With Serum IL-6 Level Greater Than the ULN (Phase 2)
Baseline and Day 4

Percent Change from Baseline in C-Reactive Protein (CRP) Levels at Day 4 in Participants with Serum Interleukin 6 (IL-6) Level Greater than the Upper Limit of Normal (ULN) Least Squares (LS) means estimate of percent change from baseline at Day 4 (raw scale) for each treatment group is based on the Analysis of Covariance (ANCOVA) model. It is defined as anti-log of the estimate of dependent variable minus 1, i.e., (exp\[ln(CRP at day 4/Baseline CRP)\]-1. Negative numbers imply improvement in CRP.

Percentage of Participants With at Least a 1-point Improvement in Clinical Status From Baseline to Day 22 Using the 7-point Ordinal Scale in Participants With Critical COVID-19 Receiving Mechanical Ventilation at Baseline (Phase 3 Cohort 1)
Day 22

The ordinal scale is an assessment of the clinical status of a participant. The 7-point ordinal scale is as follows: 1\. Death; 2. Hospitalized, requiring invasive mechanical ventilation or extracorporeal membrane oxygenation (ECMO); 3. Hospitalized, requiring non-invasive ventilation or high flow oxygen devices; 4. Hospitalized, requiring supplemental oxygen; 5. Hospitalized, not requiring supplemental oxygen - requiring ongoing medical care (COVID-19 related or otherwise); 6. Hospitalized, not requiring supplemental oxygen - no longer requires ongoing medical care; 7. Not hospitalized; higher score = less severity

PD parameters
baseline through week 4

Pharmacodynamic (PD) parameters, what a drug does to the body, will be collected from baseline through week 4: * the time to nadir (or peak) * change from baseline * area under the curve (AUC)

Frequently asked questions about Sarilumab

What is Sarilumab used for?

Sarilumab is an investigational drug being studied for COVID-19 and rheumatoid arthritis. In COVID-19, it is being evaluated in hospitalized patients. For rheumatoid arthritis, it has been studied in adults. It is currently in Phase 2 clinical development for these indications.

What does Sarilumab target?

Sarilumab targets the IL6R, which is the interleukin-6 receptor. It acts as an antagonist, meaning it blocks the activity of this receptor. By targeting IL6R, Sarilumab is designed to modulate inflammatory pathways involved in conditions like rheumatoid arthritis and COVID-19.

Who makes Sarilumab?

Sarilumab is developed by Regeneron Pharmaceuticals, Inc., a biopharmaceutical company. Regeneron's stock is traded under the ticker symbol REGN. The company is conducting clinical trials to evaluate Sarilumab's safety and efficacy in various patient populations.

What phase is Sarilumab in?

Sarilumab is in Phase 2 clinical development. It has completed a Phase 2 trial in hospitalized patients with COVID-19, which enrolled 1,912 participants. The drug is investigational and has not been approved by regulatory authorities for any indication.

What clinical trials is Sarilumab in?

Sarilumab has been studied in clinical trials including NCT04315298, a Phase 2 trial in hospitalized patients with COVID-19, and NCT02097524, a Phase 1 trial in adults with rheumatoid arthritis. Both trials are completed. The COVID-19 trial enrolled 1,912 participants in the United States.

Is Sarilumab the same as Kevzara?

Sarilumab is also known by the brand name Kevzara. It is a biologic drug that targets the IL6 receptor. In clinical trials, it has been evaluated for rheumatoid arthritis and COVID-19, with studies conducted in the United States.
