Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Lonapegsomatropin
Other interventions - Placebo
Treatment: Drugs - Somatropin

Experimental: Lonapegsomatropin - Lonapegsomatropin administered once-weekly by subcutaneous injection

Placebo comparator: Placebo - Placebo for Lonapegsomatropin administered once-weekly by subcutaneous injection

Active comparator: Somatropin - Somatropin administered once-daily by subcutaneous injection


Treatment: Drugs: Lonapegsomatropin
Due to the different hGH dose requirements, depending on subject's age and concomitant use of oral estrogen, this trial has 3 dosing groups per arm, followed by gradual increasing dose titration to a target maintenance dose.

Other interventions: Placebo
The placebo for lonapegsomatropin drug product will contain the same excipients as lonapegsomatropin drug product but does not contain lonapegsomatropin itself. The placebo solution will be administered by SC injection via syringe and needle. Due to the different hGH dose requirements, depending on subject's age and concomitant use of oral estrogen, this trial has 3 dosing groups and the placebo will receive the same dose volume as if they would have been randomized to once-weekly lonapegsomatropin.

Treatment: Drugs: Somatropin
Somatropin solution is provided in a pre-filled pen intended for daily subcutaneous injection. Due to the different hGH dose requirements, depending on subject's age and concomitant use of oral estrogen, this trial has 3 dosing groups per arm, followed by gradual increasing dose titration to a target maintenance dose.

A. For all countries except Japan: Subjects must satisfy at least one of the following criteria:
1. Insulin tolerance test: peak GH =5 ng/mL
2. Glucagon stimulation test according to body mass index (BMI)

* i. BMI =30 kg/m2: peak GH =3 ng/mL
* ii. BMI >30 kg/m2: peak GH =1 ng/mL

5. Growth hormone releasing hormone (GHRH) + arginine test according to BMI:

* i. BMI <25 kg/m2, peak GH <11 ng/mL
* ii. BMI =25-=30 kg/m2, peak GH <8 ng/mL
* iii. BMI >30 kg/m2, peak GH <4 ng/mL

B. For Japan only: Subjects with AGHD and deficiency of at least one non-GH pituitary hormones need to satisfy one of the following GH stimulation tests. Subjects with GHD and evidence of intracranial structure disorder need to satisfy at least 2 of the following stimulation tests:
1. Insulin tolerance test: peak GH =1.8 ng/mL
2. Glucagon test: peak GH =1.8 ng/mL

3. IGF-1 SDS = -1.0 at screening as measured by central laboratory.
4. hGH treatment naïve or no exposure to hGH therapy or GH secretagogue for at least 12 months prior to screening.
5. For subjects on hormone replacement therapies for any hormone deficiencies other than GH (e.g., adrenal, thyroid, estrogen, testosterone) must be on adequate and stable doses for =6 weeks prior to and throughout screening.
6. For subjects not on glucocorticoid replacement therapy, documentation of adequate adrenal function at screening defined.
7. For males not on testosterone replacement therapy: morning (6:00 - 10:00AM) total testosterone within normal limits for age.
