GHRP-6 in growth hormone deficiency and growth-hormone secretagogue pharmacology — evidence extract
The Institute's graded assessment of GHRP-6 for growth hormone deficiency and growth-hormone secretagogue pharmacology, with the contributing trials and the domain-by-domain certainty reasoning.
§1Evidence extract: Growth hormone deficiency and growth-hormone secretagogue pharmacology
§1.1Question and anchor outcome
- Population
- Insufficient endogenous growth-hormone secretion, or the pharmacological stimulation of the growth-hormone axis, assessed here principally through provocative testing and IGF-1 response.
- Intervention
- GHRP-6, subcutaneous or intravenous
- Comparator
- As used in each contributing trial; reported per trial rather than pooled across comparator types
- Anchor outcome
- Peak stimulated growth hormone
Additional outcomes the Institute extracts for this indication: Change in IGF-1 and IGFBP-3; Body composition by DXA; Glucose tolerance.
§1.2Contributing trials
Table 1. Trials contributing to the assessment of GHRP-6 in growth hormone deficiency and growth-hormone secretagogue pharmacology.
| Trial | Phase | Design | Randomised | Duration | Year |
|---|---|---|---|---|---|
| GHRP6-PH1-GH | 1 | Phase 1 ascending dose | — | Single dose | 1995 |
§1.3Certainty assessment
Table 2. Reasoning recorded against each certainty domain.
| Domain | Rating | Reasoning |
|---|---|---|
| Risk of bias | No concern | No serious concern identified in this domain. |
| Inconsistency | No concern | No serious concern identified in this domain. |
| Indirectness | No concern | No serious concern identified in this domain. |
| Imprecision | No concern | No serious concern identified in this domain. |
| Publication bias | Very serious | The evidence base is small, recent and wholly sponsor-generated. |
| Overall rating: Low certainty. Confidence in the effect estimate is limited. The true effect may be substantially different from the estimate. | ||
