Crossover Study to Assess the Safety and Pharmacokinetic of Pegylated Somatropin(PEG Somatropin) in GHD Children (Phase 1)

June 13, 2012 updated by: GeneScience Pharmaceuticals Co., Ltd.

A Phase 1, Open-Label, Single and Multiple Dose Study to Assess the Safety and Pharmacokinetics of Pegylated Somatropin(PEG Somatropin) in GHD Children

The purpose of the phase 1 study is to assess the safety and pharmacokinetics of PEG somatropin, which administered once per week, compared with the daily used somatropin, and to evaluate the safety and possibility to replace daily used somatropin.

Study Overview

Status

Status

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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

4 years to 10 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
pharmacokinetics parameter
Time Frame: Somatropin AQ: predose(0),1,2,3,4,6,8,10,12,16,20,24 hours post-dose. PEG somatropin: predose (0),2,4,8,12,18,24,36,48,72,96,120,144,168 hours post-dose
Cmax, AUC during the time interval for the first dose and last dose, Half-Life(t1/2), Apparent body clearance(CL), Mean residence time(MRT),steady-state volume of distribution(Vss)
Somatropin AQ: predose(0),1,2,3,4,6,8,10,12,16,20,24 hours post-dose. PEG somatropin: predose (0),2,4,8,12,18,24,36,48,72,96,120,144,168 hours post-dose

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
IGF-1, IGFBP-3
Time Frame: Day I to Day 7 in each treatment period (33 time points) for daily used somatropin, Day I to Day 42 in each treatment period (35 time points) for PEG somatropin
Day I to Day 7 in each treatment period (33 time points) for daily used somatropin, Day I to Day 42 in each treatment period (35 time points) for PEG somatropin

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
