Condition

Growth Hormone Deficiency

Growth hormone deficiency occurs when the pituitary gland makes too little growth hormone, which drives growth in children and helps adults maintain muscle, bone and metabolism. The strongest evidence is for macimorelin, an oral test that trials found identified adult cases with accuracy comparable to the standard insulin tolerance test. CJC-1295 raised growth hormone levels in healthy adults, but that evidence is moderate and measured hormone levels rather than patient outcomes.

Macimorelin (Macrilen): outcomes studied for Growth Hormone Deficiency
GradeOutcomeEffectSizeStudiesPeopleStudies list
Diagnostic Safety

No hypoglycemia risk unlike ITT. Well-tolerated single oral dose. Contraindicated only with strong CYP3A4 inhibitors. Can be used in patients where ITT is contraindicated (elderly, cardiovascular disease, seizure history).

GH Deficiency Diagnosis

Phase 3: 82-87% sensitivity, 92-96% specificity for AGHD diagnosis. Optimal GH cutoff 2.7-5.1 ng/mL. Accuracy comparable to insulin tolerance test (ITT). First FDA-approved oral GH stimulation test.

Improves (the measure goes up)Large effect11 studies
GH Stimulation Response

Robust GH release in healthy subjects. Peak response at 30-90 minutes. Reproducible test with low inter- and intra-individual variability. Blunted response (<5.1 ng/mL) indicates GH deficiency.
