About this study

Official title: Phase III, Multicentre, Non-comparative, Open and Single Stage Study to Assess the Efficacy and Safety of Pamoate of Triptorelin 11.25 MG in Children With Precocious Puberty

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.

Being tested
Triptorelin pamoate 11.25mg (Decapeptyl® SR)
Medical subject headings

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With a GnRH-stimulated LH Level ≤3 IU/L

    Measured: 3 months after the first injection of triptorelin pamoate 11.25 mg

Secondary outcomes (14)
  1. Number of Participants Whose Intravenous (i.v.) GnRH-stimulated LH Response Was ≤3 IU/L

    Measured: Month 6

  2. Follicle Stimulating Hormone (FSH) Level Following GnRH Test

    Measured: Screening, month 3 and 6

  3. Basal FSH Level

    Measured: Month 0, 1, 2, 3, 4, 5, and 6

  4. Basal LH Level

    Measured: Month 0, 1, 2, 3, 4, 5 and 6

  5. Number of Girls With Oestradiol Levels ≤ 20 pg/ml

    Measured: Month 0, 1, 2, 3, 4, 5 and 6

  6. Testosterone Level

    Measured: Month 0, 3 and 6

  7. Number of Girls With Inhibin B Levels < 6 pg/ml

    Measured: Month 0, 3 and 6

  8. Change From Screening in Pubertal Stage (Tanner Method) at Month 6

    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'.

    Measured: Between screening and month 6

  9. Height Standard Deviation Score (SDS)

    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.

    Measured: Month 0, 3 and 6

  10. Body Mass Index (BMI) SDS

    Measured: Month 0, 3 and 6

  11. Change From Baseline in Growth Velocity (GV) SDS at Month 6

    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.

    Measured: Baseline and month 6

  12. Difference Between Bone Age and Chronological Age

    Bone age was defined according to Greulich and Pyle method. Chronological age was calculated using the date of birth.

    Measured: Month 0 and 6

  13. Uterine Length

    Measured: Month 0, 3 and 6

  14. Triptorelin Plasma Levels

    Measured: Month 1, 2, 3, 4, 5 and 6

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Triptorelin pamoate 11.25mg (Decapeptyl® SR) in people with Precocious Puberty, run by Ipsen at 18 sites in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 Dec 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

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). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Oct 2022.
