(somatrogon-ghla)
A multi-center, randomized, open-label, active-controlled, parallel-group phase 3 study (NCT 02968004) was conducted in 224 treatment-naïve, prepubertal pediatric subjects with growth hormone deficiency (GHD). The primary efficacy endpoint was annualized height velocity at Week 52.
One hundred nine (109) subjects received 0.66 mg/kg/week NGENLA, and 115 subjects received 0.034 mg/kg/day daily somatropin. The subjects age ranged from 3 to 12 years, with a mean of 7.7 years. One hundred sixty-one (71.9%) subjects were male and 63 (28.1%) were female. One hundred sixty-seven (74.6%) subjects were White, 45 (20.1%) subjects were Asian, 2 (0.9%) subjects were Black or African-American, 1 (0.5%) subject was American Indian or Alaska Native, 1 (0.5%) subject was Native Hawaiian or Other Pacific Islander, and for 8 (3.6%) subjects race information was missing; 24 (10.7%) subjects identified as Hispanic or Latino. The subjects had a mean baseline height standard deviation score (SDS) of -2.9.
Treatment with once-weekly NGENLA for 52 weeks resulted in an annualized height velocity of 10.1 cm/year. Patients treated with daily somatropin achieved an annualized height velocity of 9.8 cm/year after 52 weeks of treatment. Refer to Table 3.

The mean height SDS at Week 52 was -1.94 in NGENLA arm and -1.99 in the daily somatropin arm. The mean increase in height SDS from baseline at Week 52 was 0.92 in NGENLA arm and 0.87 in the daily somatropin arm, respectively.
