Brief Summary:
This will be the first clinical study of the development of PHA-794428 in a pediatric population. Since differences in PK and/or PD response may occur between adult and pediatric subjects, it is deemed appropriate to first conduct an exploratory single dose study in pediatric patients to assess safety and tolerability in this patient population. In addition this will add pediatric data to facilitate the prediction of the optimal therapeutic dose to be tested in repeated dose phase 2b trials in children, using PK/PD modeling

Condition or disease Intervention/treatment Phase
Growth Hormone Deficiency Drug: PHA-794428 Phase 2

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.
