About this study

Official title: Humatrope Treatment to Final Height in Turner's Syndrome

A randomized, controlled trial in girls with Turner syndrome at least 7 years old and younger than 13 at study entry, to determine the efficacy and safety of Humatrope (somatropin) treatment in promoting linear growth to final height.

Read the detailed description

A randomized, controlled trial of Humatrope (somatropin) treatment in girls with Turner syndrome at least 7 years old and younger than 13 at study entry.

Core study objectives are to determine the efficacy of Humatrope in promoting linear growth to final height in girls with Turner syndrome, and to assess the safety of this treatment. Core study completion criteria (protocol final height) are that the patient has both a height velocity < 2 cm per year and a bone age of 14 years or greater.

Addendum 1 provides the option of Humatrope treatment to patients who were randomized to the Control arm of the Core study and who discontinued from the study on or after December 19, 1997.

Addendum 2 objectives are: 1) to collect true final height data; 2) to evaluate hearing, tympanic membrane function and other specific areas of interest with respect to the safety of growth hormone therapy in Turner syndrome; 3) to evaluate pancreatic beta cell function (glucose metabolism) in patients previously enrolled in the Core study.

Addendum 3 objective is to determine the parental origin of the retained X chromosome of an appropriate subset of patients currently or previously enrolled in the Core study, and to determine whether this parental origin holds any predictive value for spontaneous growth or for response to growth hormone therapy.

What is being measured

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

  1. Height Standard Deviation Score (SDS) (National Center for Health Statistics [NCHS]), Change From Baseline to Last Measurement, As Randomized Population

    Value analyzed is change from baseline to the most mature height measurement available. The terms Standard Deviation Score (SDS) and National Center for Health Statistics (NCHS) were defined in baseline characteristics. Greater height SDS values indicate greater height; positive values of change from baseline indicate increased height.

    Measured: Baseline, and end of 4-year addendum

  2. Height Standard Deviation Score (SDS) (National Center for Health Statistics [NCHS]), Last Measurement After Attainment of Final Height

    SDS report the number of standard deviations from the mean for age and sex for an individual measurement (normal range: -2 to +2 SDS). Height SDS [NCHS] uses the NCHS US general female population reference height values for age (Kuczmarski RJ et al. 2000) as the population mean and standard deviation. Calculation of Height SDS is provided in Height SDS [Lyon] description (Baseline). Since data reported by Kuczmarski RJ et al provides US general female population standards, values of Height SDS [NCHS] for untreated patients with Turner syndrome tend to be below zero e.g, -2.0 to -4.0 SDS.

    Measured: at completion of core study, or at end of 4-year addendum

Secondary outcomes (16)
  1. Height Standard Deviation Score (SDS) (National Center for Health Statistics [NCHS]), Change From Baseline, As-Treated Population

    Value analyzed is change from baseline to the most mature height measurement available. The terms Standard Deviation Score (SDS) and National Center for Health Statistics (NCHS) were defined in baseline characteristics. Greater height SDS values indicate greater height; positive values of change from baseline indicate increased height.

    Measured: every 3 months during core study, and at start and end of 4-year addendum

  2. Height (Centimeters [cm])

    Most mature measurement available, at or after attainment of Final Height.

    Measured: every 3 months during core study, and at start and end of 4-year addendum

  3. Number of Participants With an Abnormal Pure Tone Audiometry, Audiologist Assessment

    Measured: at completion of core study or beginning of addendum

  4. Number of Participants With Abnormal Speech Audiometry, Audiologist Assessment

    Measured: at completion of core study or beginning of addendum

  5. Number of Participants With Abnormal Impedance Tympanometry, Audiologist Assessment

    Measured: at completion of core study or beginning of addendum

  6. Number of Participants With Hearing Loss, Audiologist Assessment

    Sensorineural Hearing Loss (SNHL)=air conduction threshold >20 dB HL and air-bone gap ≤10 dB HL; Conductive Hearing Loss (CHL)= air conduction threshold >20 dB HL, bone conduction threshold ≤20 dB HL and air-bone gap >10 dB HL; Mixed Hearing Loss (MHL) = evidence of SNHL as defined above and CHL as defined above, in the same ear; Unspecified Hearing Loss (UHL)= abnormal hearing with none of SNHL, CHL, or MHL present.

    Measured: at completion of core study or beginning of addendum

    Change from core study baseline to addendum 2 maximum.

    Measured: At core study baseline, and at end of 4-year addendum

  8. Maximum Fasting Glucose Value

    Maximum measured value over addendum. In special cases an additional measurement is taken at 2 years.

    Measured: At start and through end of 4-year addendum (up to an additional 2 years)

  9. Number of Participants With Any Abnormal Fasting Glucose Value

    Indicates if patient had any measured value exceeding threshold of normality at any visit during addendum. Abnormal Fasting Glucose=Fasting Glucose >=100 milligrams per deciliter (mg/dL).

  11. Number of Participants With Any Abnormal Fasting Insulin Value

    Indicates if patient had any measured value exceeding threshold of normality at any visit during addendum. Abnormal Fasting Insulin = Fasting Insulin >=35 micro International Units per milliliter (uIU/mL).

    Measured: At start and through end of 4-year addendum

  12. Minimum Fasting Glucose/Insulin Ratio Values

    Minimum measured value over addendum. In special cases an additional measurement is taken at 2 years.

    Measured: At start and through end of 4-year addendum (up to an additional 2 years)

  13. Number of Participants With Any Abnormal Fasting Glucose/Insulin Ratio Value

    Indicates if patient had any measured value below threshold of normality at any visit during addendum. Abnormal Fasting Glucose/Insulin Ratio = Fasting Glucose/Insulin Ratio <=4.5 milligrams per 10^-4 Units (mg/10^-4U).

    Measured: At start and through end of 4-year addendum

  14. Glycosylated Hemoglobin, Change From Baseline

    Change from core study baseline to addendum 2 maximum.

A Phase 3 study testing Somatropin, Ethinyl estradiol and Medroxyprogesterone acetate in people with Turner Syndrome, run by Eli Lilly and Company at 14 sites in Canada.

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 5 inclusion and 3 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 27 Jan 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 sites in Canada. 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 27 Jan 2010). 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?

Height Standard Deviation Score (SDS) (National Center for Health Statistics [NCHS]), Change From Baseline to Last Measurement, As Randomized Population (time frame: Baseline, and end of 4-year addendum). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00191113, which also lists 5 linked publications.

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.
