DRUG TRIALS SNAPSHOT SUMMARY:
What is the drug for?
KEVZARA is used to treat adult patients with moderately to severely active rheumatoid arthritis (RA) after at least one other medicine called a disease modifying anti-rheumatic drug (DMARD) has been used and did not work well or could not be tolerated.
How is this drug used?
KEVZARA is given as an injection under the skin (subcutaneous injection) once every two weeks.
What are the benefits of this drug?
In the clinical trials, a greater proportion of patients who received KEVZARA achieved an improvement in the signs and symptoms of RA in comparison to patients who received a placebo.
Were there any differences in how well the drug worked in clinical trials among sex, race and age?
- Sex: KEVZARA worked similarly in men and women.
- Race: Most of the patients were White. Differences in how well the drug worked among races could not be determined because of the small number of patients in other races.
- Age: KEVZARA worked similarly in patients above and below age 65.
What are the possible side effects?
KEVZARA may cause life threatening infections. Other serious side effects include low neutrophil (white blood cells that help the body fight off infections) count, low platelet (blood cells that promote blood clotting) count, increased certain liver function tests, increased cholesterol, stomach or intestine tears and allergic reactions.
The most common side effects are low neutrophil count, increased certain liver function tests, injection site erythema, upper respiratory infections and urinary tract infections.
Were there any differences in side effects among sex, race and age?
- Sex: The occurrence of side effects was similar in men and women.
- Race: Most of the patients were White. Differences in the occurrence of side among races could not be determined because of the small number of patients in other races.
- Age: The occurrence of side effects was similar in participants above and below age 65.
WHO WAS IN THE CLINICAL TRIALS?
Who participated in the clinical trials?
The FDA approved KEVZARA based primarily on evidence from two clinical trials of 1740 patients with moderate to severe RA who had an inadequate response or intolerance to one or more DMARDs. The trials were conducted in the United States, Europe, Asia, Australia, and Latin and South America.
Figure 1 summarizes how many men and women were in the clinical trials.

How were the trials designed?
There were two trials that established the benefits and side effects of KEVZARA. Trials enrolled patients with moderately to severely active RA who had an inadequate response or intolerance to one or more DMARDs (Trial 1) or one or more TNF-inhibitors (Trial 2).
In Trial 1, patients taking methotrexate were randomly assigned to receive either KEVZARA (150 mg or 200 mg) or placebo every two weeks for 52 weeks. Neither the patients nor the health care providers knew which injection was being given until after the trial was completed.
In Trial 2, patients taking conventional DMARDS (methotrexate, sulfasalazine, leflunomide, and/or hydroxychloroquine) were randomly assigned to receive either KEVZARA (150 mg or 200 mg) or placebo every two weeks for 24 weeks. Neither the patients nor the health care providers knew which injection was being given until after the trial was completed.
The benefit of KEVZARA was measured by comparing the proportion of patients treated with KEVZARA who achieved an American College of Rheumatology 20 (ACR20) response at Week 24 to the proportion of patients treated with placebo who achieved an ACR20 response. ACR20 response is based on standardized criteria used to assess the benefit of arthritis medications on signs and symptoms of RA, such as improvement in the number of tender and swollen joints.
GLOSSARY
CLINICAL TRIAL: Voluntary research studies conducted in people and designed to answer specific questions about the safety or effectiveness of drugs, vaccines, other therapies, or new ways of using existing treatments.
COMPARATOR: A previously available treatment or placebo used in clinical trials that is compared to the actual drug being tested.
EFFICACY: How well the drug achieves the desired response when it is taken as described in a controlled clinical setting, such as during a clinical trial.
PLACEBO: An inactive substance or “sugar pill” that looks the same as, and is given the same way as, an active drug or treatment being tested. The effects of the active drug or treatment are compared to the effects of the placebo.
SUBGROUP: A subset of the population studied in a clinical trial. Demographic subsets include sex, race, and age groups.
