Primary Outcome Measures:
  • Change in the serum Insulin-like growth factor-I (IGF-I)concentration from baseline [ Time Frame: Months 1 thru 11 ] [ Designated as safety issue: No ]
  • Number of patients with abnormal GH stimulation tests [ Time Frame: Baseline ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change from baseline in waist circumference [ Time Frame: Month 12 ] [ Designated as safety issue: No ]
  • Age and gender specific optimal doses of GH replacement [ Time Frame: Months 1 thru 11 ] [ Designated as safety issue: No ]
  • Change in Quality of Life-Adult Growth Hormone Deficiency Assessment [ Time Frame: Months 1 thru 12 ] [ Designated as safety issue: No ]
  • Assessment of adverse events [ Time Frame: Months 1 thru 12 ] [ Designated as safety issue: No ]
  • Serum prolactin, thyroid stimulating hormone, free thyroxine serum, cortisol, adrenocorticotropic hormone, luteinizing hormone, follicle stimulating hormone, estradiol, and testosterone to assess degree of other anterior pituitary hormone deficiencies [ Time Frame: Baseline ] [ Designated as safety issue: No ]
  • Change from baseline in Glasgow Outcome Score [ Time Frame: Month 12 ] [ Designated as safety issue: No ]
  • Change in Quality of Life-Mini-Mental scores [ Time Frame: Months 1 thru 12 ] [ Designated as safety issue: No ]

Estimated Enrollment: 100
Study Start Date: November 2002
Study Completion Date: November 2003
Arms Assigned Interventions
Experimental: 1 Genetic: somatropin
Somatropin will be administered as a daily subcutaneous injection; Fixed doses starting with 0.1 mg/day in patients older than 55 years or patients weighing less than 50 kg; all other patients: 0.1 mg/day or 0.2 mg/day (these doses should all be lower than 0.04 mg/kg/week); all patients starting at 0.1 mg/day will have their dose progressively increased in 0.1 mg/day increments to a maximum clinically- and pharmacologically- tolerated plateau dose; all patients starting at 0.2 mg/day will increase in 0.2 mg/day increments; all incremented dose changes will occur at monthly intervals based on IGF-I levels; treatment will continue for 12 months

Detailed Description:
The study was terminated on October 9, 2003. The reason cited for the termination was due to poor patient recruitment and therefore not enough data could be collected to provide comprehensive analysis for reporting of results. No safety or efficacy issues were reported to cause the termination of the study.

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Documented GHD
