Meta-Analysis of Paediatric Patients with Central Precocious Puberty Treated with Intramuscular Triptorelin 11.25 mg 3-Month Prolonged-Release Formulation .
OBJECTIVE
A meta-analysis was undertaken to assess the effect of triptorelin 11.25 mg 3-month prolonged-release formulation in central precocious puberty (CPP).


METHODS
All available clinical studies with triptorelin 11.25 mg were included. The primary outcome was the proportion of children with suppressed luteinising hormone (LH) response (peak LH ≤3 IU/L) to the gonadotrophin-releasing hormone (GnRH) test 3 months after triptorelin 11.25 mg injection. Secondary outcomes included: the proportion with suppressed peak LH response at 6 months and the proportion with suppressed peak follicle-stimulating hormone (FSH) response (≤3 IU/L), suppressed oestradiol (≤20 pmol/L) in girls or suppressed testosterone (≤30 ng/dL) in boys at 3 months.


RESULTS
153 children (13 boys, 140 girls) were included. The proportion with a suppressed peak LH response to the GnRH test was 87.6% (95% CI: 81.3-92.4, p < 0.0001, for a proportion >70%) and 92.8% (95% CI: 87.5-96.4, p < 0.0001, for a proportion >70%) at 3 and 6 months, respectively. FSH peak, oestradiol, and testosterone were suppressed in 86.7% (95% CI: 79.1-92.4), 97.1% (95% CI: 91.6-99.4), and 72.7% (95% CI: 39.0-94.0) of children at 3 months, respectively.


CONCLUSIONS
Triptorelin 11.25 mg 3-month formulation is efficacious in suppressing LH peak and other gonadal hormones and in slowing the progression of CPP in children. .
