Clinical Field Study

Study results demonstrated a significantly higher proportion of inappetent dogs that received ENTYCE® (capromorelin oral solution) had an increase in appetite compared to dogs that received placebo in a large population of client-owned dogs with reduced appetite of varying etiologies.1

Study Design

  • Blinded, placebo-controlled, multi-site study
  • 244 client-owned dogs enrolled, 2:1 randomization
  • Inappetence from a variety of causes
  • 3 mg/kg once daily oral liquid for 4 days
  • All dogs enrolled in the study were evaluated for adverse reactions throughout the course of the study

 Primary Endpoint: Owner Appetite Assessment

  • Success Rate on day 4

*A dog was considered a treatment success if the owner answered that their dog’s appetite was increased in response to the question, “Do you feel that during the study (over the 4 ± 1 days of treatment) your dog’s appetite was increased, no change or decreased?”
**Treatment success was defined as an increase in total score ? 5 from day 0 to day 3 ± 1 (scoring scale 5-25)

Laboratory Effectiveness Study

The results of this study in healthy beagle dogs demonstrated a significant increase in mean (SD) food consumption for dogs treated with ENTYCE® (capromorelin oral solution) compared to dogs that received placebo over four days of treatment.2

Study Design

  • Randomized, masked, placebo-controlled study
  • 24 lab beagle dogs enrolled; 1:1 randomization
  • 3 mg/kg once-daily oral liquid for 4 days
  • Dogs observed for clinical signs throughout course of study
  • Physical exams completed prior to and end of treatment
  • Blood drawn before and after treatment for evaluation of serum chemistry and hematology parameters
