Interventions
- DrugSomatropin
Participants (n=172) will be randomized in a 1:1 ratio to rhGH (n=86) versus placebo (n=86) for six months, stratified by participating site. Both study participants and the study team will be blinded to treatment assignment. All participants will complete in-clinic follow-ups at Days 14, 40, 65, and 90 (3 months) and at day 180 (6 months). The primary outcome will be the mean difference in QoL-AGHDA scores between treatment arms at 6 months follow-up. Patients will discontinue the study intervention at 6 months, and will be followed-up two weeks subsequent, in order to assure patient safety and wellness, and to ensure maximal facilitation of patient transition back into routine care.
