Two selected reports cover intravenous ipamorelin in bowel-surgery patients and pharmacology in healthy men. Other routes, combinations and proposed uses are outside these findings.12

Bottom line from this bounded source set

The postoperative-ileus trial found no statistically significant improvement in its key or secondary efficacy analyses. The healthy-volunteer study measured growth hormone responses, which do not establish clinical benefit.12

Reviewed study record

Postoperative ileus: a placebo-controlled phase 2 trial

Design

A multicenter blinded randomized placebo-controlled study assessed recovery after bowel resection.1

Population

The trial enrolled 117 adults; 114 were included in its safety and modified intent-to-treat populations.1

Outcomes reported

Time to a tolerated solid meal was not significantly different between groups. Treatment-emergent adverse events occurred in 87.5% with ipamorelin and 94.8% with placebo.1

Limitations

The study was small and included varied underlying conditions. A nonsignificant result does not prove equivalence, and these postoperative findings do not establish safety for other uses or routes.1

Reviewed study record

Healthy-volunteer pharmacokinetics and hormone response

Design

An escalating-exposure study modeled drug concentrations and growth hormone responses.2

Population

The report describes eight healthy men at each of five exposure levels.2

Outcomes reported

The study observed an episode of growth hormone release and substantial between-person variability in pharmacodynamic responses.2

Limitations

The endpoints were pharmacology and hormone measurements, not clinical benefits. The abstract does not provide enough adverse-event detail for a safety conclusion.2
