Clinical Results

FDA Approval

The FDA approval of Egaten was based on the following:

An open label, randomized trial, conducted in Vietnam compared the efficacy of triclabendazole (two 10 mg/kg doses given 12 hours apart with food) to oral artesunate (4 mg/kg, given once daily for 10 days). One hundred patients (age range: 9-74 years) with acute symptomatic fascioliasis were randomized, 50 in each treatment group. At 3 months after treatment, 92% and 76% of patients in the triclabendazole and artesunate arms respectively, reported no clinical symptoms.

The clinical development program of triclabendazole for the treatment of fascioliasis included 6 nonrandomized, open label studies performed in Cuba, Bolivia, Peru, Chile, and Iran in a total of 245 adult and pediatric patients with stool-confirmed fascioliasis. All studies were similar in design. The studied triclabendazole doses ranged from 5 mg/kg to 20 mg/kg administered on days 1-3. Cure was defined as absence of Fasciola eggs in the stool based on the Kato-Katz method at Day 60 in patients who were positive at baseline. Across these studies, there was a finding of a dose response. Specifically, the Day 60 cure rate was highest for the 20 mg/kg dose, which was given in 2 divided doses, followed by cure rates of 88%, 80% and 50% in the 15 mg/kg, 10 mg/kg, and 5 mg/kg dose groups, respectively. The 5 mg/kg, 10 mg/kg, and 15 mg/kg dosing regimens are not approved.
