Sermorelin – Forschung

Überwiegend Mechanismus / Beobachtung

14 begutachtete Studien

Was die Evidenz sagt

Überwiegend Mechanismus / Beobachtung

Die meisten Studien zu Sermorelin sind mechanistisch oder beobachtend statt RCTs, die einen klinischen Effekt messen — betrachte die Ergebnisse als vorläufig.

Die meiste Evidenz stammt aus mittelwertigen randomisierten Studien, veröffentlicht 1986–2005 mit einer typischen Studiengröße von 19 Teilnehmenden.

Basierend auf 14 Studien · 10 RCTs · 214 Teilnehmende insgesamt

6Open-Labeln=110 · medium study1996

Einfach gesagt: GHRH administered as a once daily dose of 30 micrograms/kg GHRH-(1-29), s.c., was effective in increasing height velocity in GH-deficient children.

Thorner M, Rochiccioli P, Colle M, Lanes R, et al. · J Clin Endocrinol Metab (1996)

Multicenter open-label study of 110 previously untreated prepubertal GH-deficient children given 30 µg/kg/day GHRH(1-29) sc at bedtime for up to 1 year
Mean height velocity rose from 4.1 cm/yr at baseline to 7.2 cm/yr at 12 months; 74% rated good responders at 6 months
No adverse changes in glucose or excessive IGF-1 generation; overall well tolerated

7RCTn=32 · small study2005

Einfach gesagt: Administration of PEG-GHRH generated a clear increase in circulating GH compared with placebo... Some impairment of glucose tolerance was observed in the elderly following repeated administration.

Munafo A, Nguyen TX, Papasouliotis O, Lécuelle H, et al. · Eur J Endocrinol (2005)

Phase I randomized placebo-controlled trial of a PEGylated GHRH (designed to extend the short GHRH(1-29) half-life) in 12 young men and 20 elderly men/women
Subcutaneous dosing raised circulating GH and IGF-1 vs placebo; injection-site reactions were mild and transient
Repeated dosing in the elderly impaired glucose tolerance — a relevant safety signal for GH-axis stimulation

8Übersicht1986

Einfach gesagt: Several analogues of GHRH have been shown to be safe, sensitive and specific stimuli to GH release.

Grossman A, Savage MO, Besser GM. · Clin Endocrinol Metab (1986)

Review of GHRH biology: the active C-terminal-shortened derivatives (including the 29-residue fragment) retain GH-releasing activity
Exogenous GHRH specifically increases circulating GH and may increase growth long-term
Many children with GH deficiency respond to intravenous GHRH with an acute rise in serum GH

9RCTn=8 · very small study1995

Einfach gesagt: Peak GH levels in response to GHRH1-29NH2, GHRP-2 and the combined... administrations were observed between 20 and 45 minutes.

Tiulpakov AN, Brook CG, Pringle PJ, Peterkova VA. · Clin Endocrinol (Oxf) (1995)

Randomized crossover pharmacodynamic study in 8 healthy adult men comparing GHRH(1-29)NH2, GHRP-2, and their combination (each 1 µg/kg iv)
GHRH(1-29) produced a clear GH peak at 20-45 minutes, though lower than GHRP-2 or the combination
Characterizes the magnitude and time-course of the GH response to GHRH(1-29) in healthy adults

10RCTn=19 · very small study1997

Einfach gesagt: The use of GHRH or its analogs may be an alternative mode for restoring the GH-IGF-I axis in aging individuals.

Khorram O, Laughlin GA, Yen SS. · J Clin Endocrinol Metab (1997)

Single-blind, randomized, placebo-controlled 5-month trial in 19 adults aged 55-71, self-injecting [Nle27]GHRH(1-29)-NH2 10 µg/kg nightly
Tested whether restoring the GH/IGF-1 axis in aging is feasible with a GHRH analog rather than recombinant GH
Frames the aging/'anti-aging' question as a hypothesis about GH-axis restoration — not a demonstration of clinical anti-aging benefit

11RCTn=10 · very small study2000

Einfach gesagt: Significantly lower peak and area under the curve (AUC) GH concentrations occurred in the irradiated group.

Achermann JC, Brook CG, Hindmarsh PC. · Eur J Endocrinol (2000)

Randomized controlled study comparing GHRH(1-29)NH2 dose-response (0.05, 0.15, 1.0 µg/kg iv) in 5 post-cranial-irradiation GH-insufficient adults vs 5 matched controls
Irradiated patients had significantly lower peak and AUC GH responses at clinically relevant doses
Refines the diagnostic use of GHRH(1-29) and the pathophysiology of post-radiotherapy GH insufficiency

12Open-Labeln=16 · very small study1988

Einfach gesagt: Growth hormone remains the treatment of choice in growth hormone insufficiency.

Smith PJ, Brook CG. · Arch Dis Child (1988)

16 prepubertal GH-insufficient children treated with subcutaneous GHRH (1-40 and 1-29) for ~9 months each
73% (GHRH 1-40) and 63% (GHRH 1-29) showed a growth response; double the GHRH 1-29 dose was needed to match pulsatile GHRH 1-40
Response to conventional GH treatment was significantly better than GHRH, and height velocity improved when children were switched to GH

13RCTn=19 · very small study1997

Einfach gesagt: Restoration of this axis in age-advanced individuals, by the administration of GHRH, may enhance immune cell function.

Khorram O, Yeung M, Vu L, Yen SS. · J Clin Endocrinol Metab (1997)

Single-blind randomized placebo-controlled 5-month trial in 19 elderly adults given [Nle27]GHRH(1-29)-NH2 10 µg/kg nightly

Explored an immune-restoration hypothesis tied to GH/IGF-1 axis support in aging

14Open-Label1986

Einfach gesagt: It is proposed that GRF testing could provide a useful additional tool in the diagnosis of hGH deficiency.

Ranke MB. · Acta Paediatr Scand Suppl (1986)

Early clinical experience with synthetic GHRH(1-29) (GRF) in healthy volunteers and children with various disorders
Healthy subjects secreted GH up to ~40 ng/ml; GH-deficient children showed much lower responses than non-deficient children
Low false-positive rate supported GHRH testing as a diagnostic tool for GH deficiency
