Study Overview

Status

Status

Indicates the current recruitment status or the expanded access 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

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

3 years and older (ADULT, OLDER_ADULT, CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Before starting treatment, according to the medical history, clinical symptoms and signs, GH stimulation test and imaging examination, patients are diagnosed as GHD.
  • According to the height statistical data of Chinese children's physique development in nine cities in 2005, height is lower than the third percentile of growth curve of normal children with the same age and gender.
  • Height velocity (HV) ≤5.0 cm/yr.
  • GH stimulation test with two different mechanisms affirms that GH peak concentration of patients' plasma <10.0ng/ml.
  • Bone age (BA) ≤9 years in girls and ≤10 years in boys, at least 1 year less than his/her chronological age (CA).
  • Be in preadolescence (Tanner stage 1) and have a CA ≧ 3 years.
  • Receive no prior GH treatment within 6 months.
  • Sign informed consent.

Exclusion Criteria:

  • People with abnormal liver or kidney function (ALT> 2 times the upper limit of normal value, Cr> the upper limit of normal value).
  • Patients positive for hepatitis B core antigen (HBc), hepatitis B surface antigen (HBsAg) or hepatitis B e antigen (HBeAg).
  • People with known highly allergic constitution or allergy to the drug of the study.
  • People with severe cardiopulmonary, hematological and malignant tumors diseases or general infection and immune deficiency.
  • Potential tumor patients (family history).
  • Diabetic.
  • Abnormal growth and development, such as Turner syndrome, constitutional delay of growth and puberty, Laron syndrome, growth hormone receptor deficiency, girls of growth retardation without excluding abnormal chromosome.
  • Subjects took part in other clinical trial study within 3 months.
  • Other conditions which in the opinion of the investigator preclude enrollment into the study.
