A Phase I, Randomized, Double-blind, Placebo and Active-controlled Study of Single and Multiple Ascending Doses of GenSci134 Injection in Healthy Adults, and a Single Ascending Dose in Patients With Adult Growth Hormone Deficiency

What this Trial Is About

Researchers are evaluating the safety and tolerability of GenSci134, a drug given by subcutaneous injection, in healthy adult volunteers and adults with Growth Hormone Deficiency (AGHD). This study has two parts: the first part involves healthy volunteers in two phases—single and multiple ascending doses—and the second part includes AGHD patients receiving a single ascending dose. The trial aims to assess safety, how the drug acts in the body (pharmacokinetics and pharmacodynamics), immune responses, and other exploratory effects. In the first part, Phase Ia tests single doses of GenSci134 in healthy adult males across seven dose groups with placebo and active controls. Phase Ib evaluates multiple doses in healthy adult males and females in three dose groups. The second part, Phase Ic, studies two dose groups of AGHD patients receiving single doses of GenSci134 compared to active controls. The active comparator is recombinant human growth hormone injection given daily for 28 days. Treatments are given subcutaneously, and the study is randomized and double-blind. Participants will undergo safety assessments including monitoring adverse events for up to three months after dosing. Researchers will collect data on drug absorption, effects on the body, immune response, and tolerability. Healthy volunteers and AGHD patients will be monitored through scheduled visits involving laboratory tests and evaluations to track any side effects and responses to the treatments. The total participation duration varies by study phase and dosing schedule.
