Primary Outcome Measures:
  • Responder status at visits 9 (week 4) and 14 (week 7), where responder is defined as a patient who has achieved an IGF-1 level above the mid-point of the age-related normal range.

Secondary Outcome Measures:
  • Change in PD and glycemic control [ Time Frame: At weeks 4 and 7 ]
  • Change in PK concentrations.
  • ALT, AST greater than 3.0 times ULN at any visit
  • Anti-hGH and anti PHA-794428 antibody production
  • Change in body weight [ Time Frame: At week 4 and follow-up ]
  • Injection site reactions

Estimated Enrollment: 136
Study Start Date: July 2006
Study Completion Date: December 2007
Primary Completion Date: December 2007 (Final data collection date for primary outcome measure)
Detailed Description:
The study terminated on 10-Dec-2007. Pfizer's decision to terminate the program was due to cases of injection-site lipoatrophy that were reported in the clinical Phase 2 studies after a single injection of PHA 794428.
