A Safety, Pharmacokinetic and Pharmacodynamic Study of ACP-001 (TransCon hGH) in Adults With Growth Hormone Deficiency

A Phase 2, Multiple Dose, Open-Label, Parallel-Group, Active Controlled, Safety, Tolerability, Pharmacokinetic and Pharmacodynamic Study of ACP-001 in Adult Patients With Growth Hormone Deficiency

This study investigates the safety, tolerability, pharmacokinetic profile (PK), and pharmacodynamic response (PD) of three different doses of ACP-001 given once-a-week compared to one dose-level of an approved daily human growth hormone product over a period of 4 weeks (4 weekly administrations versus 28 daily administrations) in adults with Growth Hormone Deficiency.

Inclusion Criteria:

• Male or female between 20 to 70 years
• Body Mass Index (BMI, kg/m2) of 19.0 to 36.0 kg/m2, both inclusive

• Participation in another interventional clinical study involving an investigational compound within 3 months prior to enrolment in this study or participation in another interventional clinical study involving an investigational compound during this study.
• Subjects who are unable to comply with the requirements of the study or who in the opinion of the investigator should not participate in the study.
• History or presence of alcohol abuse or drug abuse.
