About this study

Official title: A Phase IV, Multicenter, Open-Label Study of the Immunogenicity of Nutropin AQ® V1.1 [Somatropin (rDNA Origin) Injection] Administered Daily to Naïve Growth Hormone-Deficient Children (iSTUDY)

This is a Phase IV, multicenter, open-label, single-arm study of somatropin (rDNA origin) (Nutropin AQ v1.1) in pre-pubertal children with growth hormone deficiency (GHD) naïve to prior recombinant human growth hormone (rhGH) treatment. The study is designed to characterize the immunogenicity profile of somatropin (rDNA origin) injection when administered daily subcutaneously for 12 months. The clinical impact of immunogenicity will also be assessed.

Being tested
Somatropin
Medical subject headings
Dwarfism, Pituitary

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • SomatropinDrug

    Also called Nutropin AQ v1.1

    Somatropin will be administered as SC injections at a dose of up to 0.043 mg/kg/day. The dose may be adjusted for a change in body weight of at least (plus [+]/minus [-]) 2 kilograms (kg) from baseline at the Month 6 study visit or for a change in insulin-growth factor-1 (IGF-1), as per investigator assessment.

Study groups in NCT02311894
Study groupRoleWhat they receive
SomatropinExperimentalChildren will receive daily SC injections of somatropin at a dose of up to 0.043 milligrams per kilogram per day (mg/kg/day) for 1 year.
Receives: Drug: Somatropin

What is being measured

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

  1. Percentage of Participants Who Develop Anti-GH Antibodies After Treatment With Nutropin AQ v1.1

    Participants who were tested positive to anti-GH antibody after initiation of study treatment.

    Measured: Baseline up to 1 year

Secondary outcomes (5)
  1. Percentage of Participants Who Exhibit Functional Growth Attenuation

    Growth attenuation is defined as initial growth response greater than pretreatment velocity followed by reduction in growth response to below the pretreatment velocity in the subsequent 6- to 12-month treatment period or reaching ≤ 2 cm per year.

    Measured: Baseline up to 1 year

  2. Percentage of Participants With Neutralizing Antibodies

    Among participants who developed positive anti-GH antibody post-baseline, participants who were tested positive to neutralizing anti-GH antibody during study participation.

    Measured: Baseline up to 1 year

  3. Annualized Growth Velocity at Months 6 and 12 (Change From Baseline)

    Annualized growth velocity is defined as (height - baseline height) / (date of height assessment - date of baseline)*365.25. Results are presented according to anti-GH antibody status (positive included all participants that were anti-GH antibody positive at least once post-baseline visit and anti-GH antibody negative population included all participants that were anti-GH antibody negative at all post-baseline visits).

    Measured: Months 6, 12

  4. Height Standard Deviation Score (SDS) at Months 6 and 12 (Change From Baseline)

    Height Standard Deviation Score (SDS) allows for the comparison of a participants height to that of others in the same age group. Therefore, the average height for that age group will have the SDS of 0. In this study, the starting Height SDS score was ≤ -1.5 (≤ 5th percentile). Results are presented according to anti-GH antibody status (positive included all participants that were anti-GH antibody positive at least once post-baseline visit and anti-GH antibody negative population included all participants that were anti-GH antibody negative at all post-baseline visits.

    Measured: Months 6, 12

  5. Percentage of Participants With Adverse Events

    Among participants who received at least one dose of study drug, those who reported at least one adverse event during study participation.

    Measured: Baseline up to 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Somatropin in people with Growth Hormone Deficiency, run by Genentech, Inc. at 33 sites in United States.

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 6 inclusion and 15 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 8 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 33 sites in United States. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 15 Nov 2018). 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?

Percentage of Participants Who Develop Anti-GH Antibodies After Treatment With Nutropin AQ v1.1 (time frame: Baseline up to 1 year). 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 8 Jan 2019.
