DRUG TRIALS SNAPSHOT SUMMARY:
What is the drug for?
EGATEN is used to treat fascioliasis in patients 6 years of age and older.
Fascioliasis is an infectious disease caused by the parasitic flatworms Fasciola hepatica and gigantica, also known as liver flukes. The initial infection is characterized by fever, abdominal pain, and increase elevation in liver enzymes. Over months to years, the disease may become chronic with occasional pain in the abdomen, jaundice, anemia, and blockage of bile ducts where adult flukes live. During this phase, parasite eggs are present in the stool.
How is this drug used?
EGATEN is a tablet taken by mouth in two divided doses 12 hours apart. The total dose is determined by the patient’s weight.
What are the benefits of this drug?
In clinical trials, more than 90% of patients treated with EGATEN were cured of their clinical symptoms or no longer had parasite eggs in their stool.
Were there any differences in how well the drug worked in clinical trials among sex, race and age?
- Sex: EGATEN works similarly in males and females.
- Race: Data not collected.
- Age: EGATEN works similarly among tested age groups.
What are the possible side effects?
EGATEN may cause heart rhythm problems (QT prolongation) especially in those who have underlying heart rhythm problems or who take drugs that alter heart rhythm. The most common side effects of EGATEN are pain in the abdomen, sweating, nausea, decreased appetite and headache.
Were there any differences in side effects among sex, race and age?
- Sex: The occurrence of side effects was similar in males and females.
- Race: Data not collected.
- Age: The majority of patients were less than 65 years of age; therefore, differences in side effects between younger and older age group (geriatric) could not be determined.
WHO WAS IN THE CLINICAL TRIALS?
Who participated in the clinical trials?
The FDA approved EGATEN based primarily on evidence from 9 clinical trials of 466 patients with fascioliasis. Because these were old trials and not conducted under FDA authority, some demographic data were incomplete.
Six trials were conducted between 1989 and 1992 in Iran, Bolivia, Peru, Cuba, and Chile under the World Health Organization authority.
The FDA also considered data from 3 published trials conducted under local authorities: the first one was conducted from 2004-2005 in Vietnam, second from 2007-2010 in Egypt and the third one from 2001-2006 in Peru.
Figure 1 summarizes by sex how patients were in the combined nine clinical trials.

How were the trials designed?
There were nine trials that provided data for assessment of benefit and side effects of EGATEN.
The six trials done under WHO authority enrolled patients with fascioliasis as documented by the presence of parasite eggs in the stool. Patients received various doses of EGATEN. The treatment lasted one to three days. Both patients and investigators knew which treatment was given. The benefit of EGATEN was evaluated after 60 days by counting the number of patients who no longer had parasite eggs in their stool.
The trial conducted in Vietnam enrolled patients who had symptoms of fascioliasis. Half of the patients received EGATEN and half received a drug called artesunate which is used to treat another parasitic disease. EGATEN was given twice for one day and artesunate once a day for 10 days. Both patients and the investigators knew which treatment was given. The benefit of EGATEN was evaluated 90 days after the treatment by counting the number of patients who did not have symptoms.
The two additional trials provided supportive evidence for EGATEN.
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.
