A new DRUG TRIALS SNAPSHOT is now available
Drug Trial Snapshot: XERAVA
XERAVA is a drug for the treatment of complicated intra-abdominal infections caused by bacteria in patients 18 years and older. It should be used only when the infection is caused by bacteria that are sensitive to XERAVA. Complicated intra-abdominal infections are serious infections that extend beyond the digestive organs into the intra-abdominal cavity and require treatment in the hospital.
A healthcare provider injects XERAVA directly into the bloodstream through a needle in the vein. This is known as an intravenous, or IV infusion. It takes about 60 minutes to receive an XERAVA infusion. XERAVA is given once every 12 hours for a total of 4 to 14 days. The amount of drug used depends on the patient’s weight

DRUG TRIALS SNAPSHOT SUMMARY:
What is the drug for?
XERAVA is a drug for the treatment of complicated intra-abdominal infections caused by bacteria in patients 18 years and older. It should be used only when the infection is caused by bacteria that are sensitive to XERAVA.
Complicated intra-abdominal infections are serious infections that extend beyond the digestive organs into the intra-abdominal cavity and require treatment in the hospital.
How is this drug used?
A healthcare provider injects XERAVA directly into the bloodstream through a needle in the vein. This is known as an intravenous, or IV infusion. It takes about 60 minutes to receive an XERAVA infusion.
XERAVA is given once every 12 hours for a total of 4 to 14 days.
The amount of drug used depends on the patient’s weight.
What are the benefits of this drug?
The benefit of XERAVA in patients with complicated intra-abdominal infections was similar to ertapenem and meropenem (medications used to treat complicated intra-abdominal infections).
Were there any differences in how well the drug worked in clinical trials among sex, race and age?
- Sex: XERAVA worked similarly in men and women.
- Race: The majority of patients in the trial 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: XERAVA worked similarly in patients younger and older than 65 years of age.
What are the possible side effects?
XERAVA may cause serious side effects, including severe allergic reactions, and a severe form of diarrhea caused by Clostridium difficile bacterium.
XERAVA like other antibacterial medications called tetracyclines may stain teeth, and cause thinning of the outer protective layer of teeth and decreased bone growth in the children up to 8 years old.
The most common side effects are infusion-site reactions, nausea, and vomiting.
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: The majority of patients in the trial were White. Differences in the occurrence of side effects 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 patients younger and older than 65 years of age.
WHO WAS IN THE STUDIES?
Who participated in the clinical trials?
The FDA approved XERAVA based on evidence primarily from two clinical trials (Trial 1/NCT01844856 and Trial 2/NCT02784704) of 1037 patients with complicated intra-abdominal infections. The trials were conducted in Europe, South Africa, and the United States.
The safety population is presented below. Demographics of the patients who provided data for evaluation of benefit (efficacy population) are presented in Table 7, under the MORE INFO section.
Figure 1 summarizes how many men and women were in the clinical trials used to evaluate safety.

FDA Review
How were the trials designed?
The benefit and side effects of XERAVA were evaluated in two clinical trials. The trials enrolled adult patients hospitalized with complicated intra-abdominal infections that required surgery or drainage.
In Trial 1, patients were assigned to XERAVA every 12 hours by intravenous infusion or ertapenem (a medication to treat complicated intra-abdominal infections) every 24 hours by intravenous infusion. In Trial 2, patients were assigned to XERAVA every 12 hours by intravenous infusion or meropenem (a medication to treat complicated intra-abdominal infections) every 8 hours by intravenous infusion. Treatment was for 4 to 14 days. Neither the patients nor the investigators knew which treatment was being given until after the trial was completed.
Patients were evaluated for clinical cure 25 to 31 days after treatment assignment. Clinical cure meant that either signs and symptoms of the infection were absent or that signs and symptoms of the infection were significantly improved. The benefit of XERAVA was assessed by comparing the clinical cure in patients treated with XERAVA to the clinical cure in patients treated with ertapenem or meropenem.
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.
