Study of Recombinant Human Insulin-Like Growth Factor I in Patients With Severe Insulin Resistance

PROTOCOL OUTLINE: This is an open label study. Patients receive the first dose of subcutaneous recombinant human insulin-like growth factor I (rhIGF-I) on day 7. Patients receive rhIGF-I twice daily 15-30 minutes before breakfast and dinner, and are hospitalized for the first week of therapy. Patients return for an outpatient exam on day 19 of rhIGF-I therapy. Approximately 30 days into the therapy, patients are readmitted to the clinical center for repeat screening tests. Patients then receive maintenance therapy of rhIGF-I for up to 6-12 months. A washout period follows the maintenance therapy phase. Patients are followed weekly, biweekly, or monthly depending on blood glucose response of patients off rhIGF-I therapy. Weekly phone contact with study coordinator is mandatory during this time.
