ClinicalTrials.gov Identifier:
NCT00564850
First received: November 27, 2007
Last updated: February 9, 2012
Last verified: February 2012
  Purpose

The purpose of the study is to assess the efficacy of triptorelin 11.25 mg pamoate in the delay of premature onset of puberty in girls less than 9 years and boys less than 10 years. This is measured by assessing the proportion of children who have a suppressed Luteinizing Hormone (LH) response to Gonadotropin Releasing Hormone (GnRH) test performed 3 months after injection with triptorelin 11.25 mg.

Primary Outcome Measures:
  • Number of Participants With a GnRH-stimulated LH Level ≤3 IU/L [ Time Frame: 3 months after the first injection of triptorelin pamoate 11.25 mg ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Number of Participants Whose Intravenous (i.v.) GnRH-stimulated LH Response Was ≤3 IU/L [ Time Frame: Month 6 ] [ Designated as safety issue: No ]
  • Follicle Stimulating Hormone (FSH) Level Following GnRH Test [ Time Frame: Screening, month 3 and 6 ] [ Designated as safety issue: No ]
  • Basal FSH Level [ Time Frame: Month 0, 1, 2, 3, 4, 5, and 6 ] [ Designated as safety issue: No ]
  • Basal LH Level [ Time Frame: Month 0, 1, 2, 3, 4, 5 and 6 ] [ Designated as safety issue: No ]
  • Number of Girls With Oestradiol Levels ≤ 20 pg/ml [ Time Frame: Month 0, 1, 2, 3, 4, 5 and 6 ] [ Designated as safety issue: No ]
  • Testosterone Level [ Time Frame: Month 0, 3 and 6 ] [ Designated as safety issue: No ]
  • Number of Girls With Inhibin B Levels < 6 pg/ml [ Time Frame: Month 0, 3 and 6 ] [ Designated as safety issue: No ]
  • Change From Screening in Pubertal Stage (Tanner Method) at Month 6 [ Time Frame: Between screening and month 6 ] [ Designated as safety issue: No ]
    Pubertal stage (graded from 1 to 5 for penis and breast development, graded from 1 to 6 for pubic hair development) according to the Tanner method was collected. A low stage (i.e. 1) corresponds to a pre-pubertal stage and a high stage (i.e. 5 or 6) to an adult stage. Any increase of grade was defined as 'increased' and no change in grade or a reduced grade was defined as 'stabilised or reduced'.

  • Height Standard Deviation Score (SDS) [ Time Frame: Month 0, 3 and 6 ] [ Designated as safety issue: No ]
    Standard deviation (SD) is a standard term used in growth studies and represents Standard Deviations calculated as the patient value minus the mean divided by the standard deviation. Standard Deviation Scores vary depending on the age and sex of the child.

  • Body Mass Index (BMI) SDS [ Time Frame: Month 0, 3 and 6 ] [ Designated as safety issue: No ]
  • Change From Baseline in Growth Velocity (GV) SDS at Month 6 [ Time Frame: Baseline and month 6 ] [ Designated as safety issue: No ]

    Change from baseline of GV was calculated as: GV at month 6 - GV at baseline. GV SDS was calculated using SAS algorithm.

    Growth velocity during the study was calculated using the two height measures as: GV = (Height at baseline - Height at screening)*365/delay between two height measures.


  • Difference Between Bone Age and Chronological Age [ Time Frame: Month 0 and 6 ] [ Designated as safety issue: No ]
    Bone age was defined according to Greulich and Pyle method. Chronological age was calculated using the date of birth.

  • Uterine Length [ Time Frame: Month 0, 3 and 6 ] [ Designated as safety issue: No ]
  • Triptorelin Plasma Levels [ Time Frame: Month 1, 2, 3, 4, 5 and 6 ] [ Designated as safety issue: No ]
