Study Endpoints

Primary Endpoints

Change From Baseline in Height-Standard Deviation Score (H-SDS) of Recombinant Human Growth Hormone (r-hGH) Treated Subjects at Year 3
Baseline (Month 0), Year 3

Height was calculated in standardized units expressed as the standard deviation score (SDS), where SDS = (x - m)/sigma, in which x represents the height variable measured by sex and age, and m and sigma are the statistical parameters (mean and standard deviation) for the Sempe reference population. The reference population was the historical cohort consisting of non-treated subjects with Hypochondroplasia (HCH). SDS indicated how many standard deviations higher (in case of positive SDS) or lower (in case of negative SDS) a participant's value was relative to the mean of the reference population. The scores were centered around zero. Negative score indicated smaller height for the respective age/gender.

Frequently asked questions about Recombinant human growth hormone

What is recombinant human growth hormone used for in hypochondroplasia?

Recombinant human growth hormone is being studied for use in hypochondroplasia, a rare genetic condition affecting bone growth. It is intended to improve growth in children with this condition, with treatment lasting at least three years or until near final height is reached.

Who makes recombinant human growth hormone?

Recombinant human growth hormone is developed by Merck & Company, Inc., a pharmaceutical company traded on the New York Stock Exchange under the ticker symbol MRK.

What phase is recombinant human growth hormone in?

Recombinant human growth hormone is in Phase 2 clinical development for hypochondroplasia. It is an investigational therapy, meaning it has not yet been approved by regulatory authorities and is still being evaluated in clinical trials.

What clinical trials is recombinant human growth hormone in?

Recombinant human growth hormone has been studied in one completed Phase 2 clinical trial, identified as NCT01111019. This trial evaluated the efficacy and safety of the drug in children with hypochondroplasia in France, enrolling 19 participants aged 3 years and older.

Is recombinant human growth hormone the same as Saizen?

Yes, recombinant human growth hormone is also known as Saizen. The clinical trial NCT01111019 specifically evaluated the Saizen brand of recombinant human growth hormone in children with hypochondroplasia.
