Three-times-weekly Versus Daily Growth Hormone (GH) Treatment in naïve GH-deficient Children (GH 3 wk dose)

October 25, 2017 updated by: Carla Giordano, University of Palermo

More Favorable Metabolic Impact of Three-times-weekly Versus Daily Growth Hormone (GH) Treatment in naïve GH-deficient Children

Growth hormone (GH) treatment in patients with GH deficiency (GHD) is commonly administered daily, although the pulsatile GH secretion is unlikely to be achieved and this regimen is often not complied. The auxological effect of three injections per week (TIW) regimen is controversial, while the metabolic effects were never evaluated in children. The objective of this study was to evaluate whether two different regimens of weekly injections could lead to similar auxological and metabolic effects in children with GHD.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Thirty-two children with growth hormone (GH) deficiency (25 males, mean age 10.5 ± 2.2 yr) were randomly assigned to receive daily (group A, No 16) or three injections per week (group B, No 16) GH therapy for 12 months.

Auxological parameters, insulin-like growth factor-I (IGF-I), glucose and insulin during an oral glucose tolerance test, glycosylated hemoglobin, lipid profile, the oral disposition index (DIo), the homeostasis model assessment estimate of insulin resistance (Homa-IR), the quantitative insulin sensitivity check index (QUICKI) and the insulin sensitivity index (ISI) were evaluated in the two groups of patients.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

6 years to 12 years (Child)

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: group A
Sixteen growth hormone (GH) deficiency children were assigned to receive daily growth hormone therapy for 12 months. The investigators used an initial weekly dose of 0.175 mg/kg (corresponding to the daily dose of 0.025 mg/Kg) of GH with a gradual increase every 6 months in order to always maintain the insulin growth factor (IGF)-I levels in the normal range. In detail, from months 1 to 6 the investigators used the mean weekly dose of 0.175 mg/kg and from months 6 to 12 the mean weekly dose of 0.20 mg/kg.
Drug: Growth Hormone
Active Comparator: group B
Sixteen growth hormone (GH) deficiency children were assigned to receive three time weekly growth hormone therapy for 12 months. The investigators used an initial weekly dose of 0.175 mg/kg (corresponding to the daily dose of 0.025 mg/Kg) of GH with a gradual increase every 6 months in order to always maintain the insulin growth factor (IGF)-I levels in the normal range. In detail, from months 1 to 6 the investigators used the mean weekly dose of 0.175 mg/kg and from months 6 to 12 the mean weekly dose of 0.20 mg/kg.
