Study type
Interventional
Description of intervention(s) / exposure
Single ascending dose study of safety, tolerability and pharmacokinetics of Capromorelin.
Three single ascending oral doses (20, 50 and 100 mg) at least one week apart administered to each of two groups (spinal cord injured and able-bodied).
Participants only progressed to a higher dose after successfully tolerating the prior dose at the lower level.

No known adverse events. Monitoring of vital signs, physical examination and laboratory test assessment.
Timepoint [2] 292711 0
Immediately following each doseup to 24 hours, then at 1 week and 3 weeks after final dose.
Secondary outcome [1] 309536 0
Pharmacokinetic behaviour.
Assessed by monitoring of plasma levels of the parent drug analysed by a validated liquid chromatography tandem mass spectrometry assay.
Timepoint [1] 309536 0
At each dose level one week apart using a full pharmacokinetic blood sampling profile base on reported plasma half-life of the drug. Sampling from an indwelling catheter in the cubital vein at -30 mins (pre-dose) and at +20 mins, +30 mins, +40m mins, +1 hr, +1.5 hr, +2 hr, +2.5 hr, +3 hr, +3.5 hr, +4 hr, +5 hr, +6 hr, +7 hr, +8 hr and +12 hr post dose.

Statistical methods / analysis
No power calculations were conducted. A target of n=10 per group was chosen as a reasonable number to start a preliminary study. Rationale being that it was expected to be achievable with the limited nature of the SCI population from which to draw participants and it was sufficient to provide simple comparative statistics. The number of participants per group was deliberately limited with consideration also given to the impact of the intensive blood sampling required for pharmacokinetic analyses.
Non-compartmental pharmacokinetic analyses were performed.
As were parametric statistical analyses for group comparison by analysis of variance.

Summary
Brief summary
Capromorelin (CP424391) is a ghrelin receptor agonist which shows evidence of promoting defecation and may be of use in spinal cord injury (SCI) patients to promote bowel movements. The purpose of the study was to evaluate the safety profile, tolerability, pharmacokinetics and pharmacodynamics following single oral doses of 20, 50 and 100 mg of Capromorelin in SCI and in able-bodied participants.
