Height velocity improved, as did height standard deviation.By year 3, patients were a mean of 1.25 SDs below expected height – a significant improvement over baseline.All subjects received one injection per month for 5 months.Cohort A comprised 21 men and women aged 35 years or older, who took 0.6 mg/kg per month.The first 12 months of the study consisted of dose-ranging trials, with initial doses of 5 mg/kg each month, then 2.5 mg/kg twice a month, and then 1.15 mg/kg weekly.During the last 2 years of the study, all children were taking 3.5 mg/kg, once a month.Other adverse events were headache, extremity pain, arthralgia, and musculoskeletal pain.Although the numbers were small overall, reports did increase after all the children were switched to the 3.5-mg/kg dose.
