The study will investigate the efficacy, safety and pharmacokinetics of triptorelin 22.5 mg 6-month formulation in 44 patients suffering from central precocious puberty. The null hypothesis of the study is that the proportion of patients achieving luteinizing hormone (LH) suppression to prepubertal levels at Month 6 is 80%.

Primary Outcome Measures:
  • Percentage of children with LH suppression to prepubertal levels at Month 6. [ Time Frame: Month 6 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Percentage of children with LH, FSH, estradiol/testosterone suppression to prepubertal levels and triptorelin serum levels at Months 1, 2 ,3 ,6 ,9 and 12. Incidence of adverse events, changes in growth and sexual maturation. [ Time Frame: Each visit throughout the study ] [ Designated as safety issue: No ]

Enrollment: 44
Study Start Date: April 2012
Study Completion Date: July 2014
Primary Completion Date: August 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Triptorelin 6 months
Single arm study: 2 injections of 6-month formulation of Triptorelin
Drug: Triptorelin 22.5 mg
2 IM injections at Day 1 and Day 169
Other Name: Trelstar 22.5 mg

Detailed Description:

Two injections of the triptorelin 6-month formulation will be administered by the intramuscular route at an interval of 24 weeks. The total study duration per patients will be 12 months (48 weeks).


Ages Eligible for Study:   2 Years to 9 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion criteria:

  1. Onset of development of sex characteristics before 8 and 9 years in girls and boys, respectively (breast development in girls or testicular enlargement in boys according to the Tanner method), and candidate to receive at least 12 months of GnRH agonist therapy after study entry.
  2. Aged 2-8 years inclusive (i.e. < 9 years) for girls and 2-9 years inclusive (i.e. < 10 years) for boys at initiation of triptorelin treatment.
  3. Initiation of triptorelin treatment at the latest 18 months after onset of the first signs of precocious puberty.
  4. Difference (Δ) bone age (Greulich and Pyle method) - chronological age ≥ 1 year.
  5. Pubertal-type LH response 30 minutes following a GnRH agonist stimulation test before treatment initiation (leuprolide acetate 20 μg/kg SC) ≥ 6 IU/L.
  6. Clinical evidence of puberty, defined as Tanner Staging ≥ 2 for breast development for girls and testicular volume ≥ 4 mL (cc) for boys.
  7. Informed consent signed by one parent or both parents (as per local requirements), by the liable parent or by the legal guardian (when applicable); assent signed by the child if ≥ 7 years.

Non-inclusion criteria:

  1. Gonadotropin-independent (peripheral) precocious puberty: extra pituitary secretion of gonadotropins or gonadotropin-independent gonadal or adrenal sex steroid secretion.
  2. Non-progressing isolated premature thelarche.
  3. Presence of an unstable intracranial tumour or an intracranial tumour requiring neurosurgery or cerebral irradiation. Patients with hamartomas not requiring surgery are eligible.
  4. Evidence of renal (creatinine > 2 x ULN) or hepatic impairment (bilirubin or ASAT > 3 x ULN).
  5. Any other condition or chronic illness or treatment possibly interfering with growth or other study endpoints (e.g. chronic steroid use [except mild topical steroids], renal failure, diabetes, moderate to severe scoliosis, previously treated intracranial tumour).
  6. Prior or current therapy with a GnRH agonist, medroxyprogesterone acetate, growth hormone or insulin-like growth factor-1 (IGF 1).
  7. Major medical or psychiatric illness that could interfere with study visits.
  8. Diagnosis of short stature, i.e. > 2.25 SD below the mean height for age.
  9. Positive pregnancy test.
  10. Known hypersensibility to any of the test materials or related compounds.
  11. Use of anticoagulants (heparin and coumarin derivatives).
