Clinical Field Study

The results of this study demonstrated ENTYCE® (capromorelin oral solution) to be well-tolerated in a large population of client-owned dogs with varying ages and breeds with concomitant medications and clinical conditions.1 Capromorelin related events were mild with some adverse events consistent with a restored appetite.

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

*The following adverse reactions were reported in <1% of dogs that were administered ENTYCE, increased fecal volume, increased gut sounds and polyuria.

12-Month Safety Study

Study results demonstrated that capromorelin was well-tolerated in healthy beagles at daily doses up to 40 mg/kg (17.5x the labeled dose) for 12 months, supporting a wide safety margin for use in dogs. Minimal toxicity was observed across multiple body systems when capromorelin was administered at doses substantially higher than the labeled dose over an extended period.2

Study Design

  • Beagle dogs (n=32) received either oral placebo or 0.3, 7, or 40 mg/kg capromorelin oral solution administered once-daily for 12 consecutive months
  • Safety was evaluated by physical examinations, including electrocardiogram (ECG), ophthalmic examinations and comprehensive clinical pathology
