About this study

Official title: Evaluation of the Adult Height Gain With Growth Hormone Treatment in Children With Congenital Adrenal Hyperplasia (CDAH), Using the OPALE Prediction Model

Congenital adrenal hyperplasia (CAH) is a genetic rare disease, which alters the adrenal production of gluco and mineralo corticoids. The treatment consists in supplementing children using hydrocortisone. Despite care for these children has improve substantially across decades, short adult height still remains an important consequence of the disease. About 20 % of patients have an AH below 2 standard deviations compared to their expected height.

In the OPALE model study, the investigators have collected data from a cohort of 496 French patients, born between 1970 and 1991 and with a known genotype. Using their age, sex, growth, disease, bone maturation and pubertal data, they have built a model which allows to predict their AH using data available at 8 years of age. This model has shown that the currently used formula to calculate the predicted AH (Bayley Pineau's method) is not applicable to children with CAH.

In this project, the investigators plan to use the prediction model to compare the AH in patients who have received GH treatment to their predicted AH using the model.

The hypothesis is that GH improves the AH in such patients. Existing cohorts have shown improved growth celerity, and growth expectation using the Bayley-Pineau formula), but this has not been shown on the actual AH.

This study will allow to reinforce the investigators' hypothesis.

What is being measured

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

  1. Adult height (AH) gain

    Difference between AH predicted by the OPALE model, and observed AH defined as (i) the height recorded after age 20 in boys or 18 in girls; (ii) the height recorded when bone age (BA) is ≥ 18 years in boys and 16 years in girls (99.6% of AH) (10); or (iii) the height measured after growth velocity drop to ≤ 1 cm/year

    Measured: up to 18 years

Secondary outcomes (1)
  1. Number of treatment withdrawal due to adverse events

    Safety

    Measured: up to 6 years of GH treatment

Questions about this trial

What is this clinical trial studying?

An observational study of Adrenal Hyperplasia, Congenital, run by Hospices Civils de Lyon at 1 site 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 1 inclusion and 1 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 22 May 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Adult height (AH) gain (time frame: up to 18 years). 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 22 May 2017.
