Study summary

This study is conducted in the United States of America (USA). The aim of this observational study is to collect data concerning the treatment outcomes and safety for children and adults who are prescribed Norditropin®. Specific objectives include: 1) developing models defining the relationship of Norditropin dose to changes in insulin-like growth factor (IGF-I) and treatment outcomes, accounting for independent factors such as age, gender and puberty and 2) determining the relative predictive values of peak growth hormone (GH) and IGF-I levels and other factors before treatment to clinical outcomes.

Study population

Patients from both general and specialty practice settings, existing and new users of growth hormones, who have been deemed appropriate to receive Norditropin® as part of routine out-patient care by the prescribing physician.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • obtained
  • Children or adult patients treated with Norditropin® for an appropriate condition as prescribed by their physician

Exclusion criteria

Exclusion Criteria:

  • Patients not being treated with Norditropin®
  • Patients who have discontinued treatment with Norditropin®
  • Known or suspected allergy to Norditropin® or related products
  • for somatropin treatment consistent with the Prescribing Information for Norditropin®
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

What researchers measure

Primary outcomes

  1. Change in height, measured as the height standard deviation score (HSDS), from the measurement made by the physician at study entry to the most recent clinic observation, end of GH treatment, de-registration, or change of clinic.

    Time frame: measurement made by physician at study entry, annually, or more frequently at physician discretion during the study.

  2. Change in waist/hip circumference ratio for adult patients

    Time frame: measurement made by physician at study entry, annually, or more frequently at physician discretion during the study

Secondary outcomes

  1. Short-term: Height, Height velocity, Height velocity standard deviation score (SDS), predicted adult height, height SDS for bone age, Proportion achieving height SDS > -2 at end of observational duration period

    Time frame: measurement made by physician at study entry, annually, or more frequently at physician discretion during the study.

  2. Final Height (or Adult height), Final Height SDS, near-adult height, near-adult height SDS, Final Height - Target Height, Final height - predicted adult height, height age

    Time frame: measurement made by physician at study entry, annually, or more frequently at physician discretion during the study.

  3. Final Height SDS - Target Height SDS, Final height SDS - predicted adult height SDS

    Time frame: measurement made by physician at study entry, annually, or more frequently at physician discretion during the study.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jun 2002 to primary completion in Sep 2016, 171 months.

Of 30 observational studies under Dwarfism, Pituitary, half reached primary completion within 85 months of starting (the median), counting those still running; a quarter within 54 and three quarters within 102. This study's 171 months is above that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 12, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
