Primary outcomes1

Outcomes the sponsor listed as primary.

  1. Number of Participants With Adverse Events (AEs)

    Time frame · From first dose of study drug up to approximately 2 years

    Registry description

    An AE was defined as any untoward medical occurrence that develops or worsens in severity during the conduct of a clinical study and does not necessarily have a causal relationship to the study drug. SAEs included death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, or an important medical event that jeopardized the participant and required medical intervention to prevent 1 of the outcomes listed in this definition. A summary of serious and non-serious AEs regardless of causality is located in 'Reported Adverse Events module'.

Secondary outcomes(6)
  1. Average Dose Level During Titration/Maintenance

    Time frame · Up to Month 12

    Registry description

    Total average dose received by a participant during titration/maintenance has been reported.

  2. Number of Participants With Dose Adjustments

    Time frame · Months 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12

    Registry description

    The number of participants with a dose adjustment (titrated up/down) at each month are summarized.

  3. Number of Participants Who Were Anti-drug Antibody (ADA) Positive

    Time frame · Up to approximately 2 years

  4. Number of Participants With Positive Neutralizing Antibodies (NABs)

    Time frame · Up to approximately 2 years

  5. Change From Baseline in Mean Insulin-like Growth Factor 1 (IGF-I) Standard Deviation Score (SDS) at Specified Timepoints During Maintenance Period

    Time frame · Baseline, Month 2 Day 1, Month 2 Day 8, Month 3 Day 1, Month 3 Day 8, Month 4 Day 1, Month 4 Day 8, Month 5 Day 1, Month 5 Day 8, Month 6 Day 1, Month 6 Day 8, Month 7 Day 1, Month 7 Day 8, Month 8 Day 1, Month 8 Day 8, Month 10 Day 1, and Month 10 Day 8

    Registry description

    Changes in the IGF-I levels were assessed as Standard Deviation Scores (SDS). The SDS was calculated as the actual value of IGF-I minus mean reference value of IGF-1 divided by reference standard deviation of IGF-I. The mean and the standard deviation (SD) vary depending on the age and sex of the participant. Change in IGF-I level (SDS) at specified timepoints from baseline was assessed. A higher score reflects a better outcome.

  6. Mean Insulin-like Growth Factor-binding Protein 3 (IGFBP-3) SDS During Maintenance Period

    Time frame · Baseline up to Month 12

SomavaratanParticipants received once-monthly SC somavaratan per Protocol Version 1.0. The dosing regimen was then modified in Protocol Version 2.0 to twice-monthly SC somavaratan. Doses were titrated to each participant's individual IGF-I responses based on the IGF-I level 7 days postdose until a maintenance dose was achieved. Maintenance dose was defined as an IGF-I value between 0 and 2.0 SDS for two consecutive 7-day postdose time points (Day 8, peak level). Participants who received somavaratan once-monthly in this study or in a previous somavaratan study (15VR7), had their dose decreased by half (minimum dose of 20 mg, 40 mg for women on estrogen, rounded down to the nearest even number) and were titrated based on IGF-I level at Day 8. New participants enrolling in this study received a starting dose of 20 mg twice-monthly (40 mg for women on estrogen) and were titrated based on IGF-I level at Day 8. Maintenance doses were adjusted further based on PD data at the discretion of the Investigator or Medical Monitor. The maximum allowable dose of somavaratan was 250.0 mg.0 / 365 / 3630 / 36
