研究概览
简要总结
This study aims to assess the safety, tolerability and Pharmacokinetics/ Pharmacodynamics (PK/PD) profile of three doses of MOD-4023 on a weekly regime and one dose on an every-other-week regime administered for a period of 4 weeks in Growth Hormone Deficient Adult (GHDA) patients who previously were on a stable r-hGH treatment. An additional extension period of 16 weeks once-weekly administration of MOD-4023 aims to confirm the dose selection for future trials.
详细描述
The study is a phase II, randomized, open-label, parallel, 4 active treatment arms study to evaluate the safety, tolerability and PK/PD profile of MOD-4023 in pre-treated, normalized, GHD adults.
The study is conducted in 2 stages. Stage I is a 4-week treatment period with 4 different dose levels/dosing regimens.
Stage II is a 16-week treatment-extension period in which all the patients will start with the same dose (derived from stage I) and will be dose titrated to maintain IGF-1 levels within the normal range.

结局指标
主要结局
1. Safety and Tolerability
时间窗: Following 4 weeks of MOD-4023 treatment
Adverse events (AE's), vital signs, electrocardiogram (ECG), laboratory tests, local reaction
Maintenance of normal Insulin-like-Growth-Factor-1 (IGF-1)levels in GHDA
时间窗: Following 4 weeks MOD-4023 treatment
The primary efficacy endpoint will be the mean time interval of IGF-I levels that lay within ±1.5 SDS after the last dose administration during stage I (4w treatment) expressed in hours.
次要结局
- Change of IGF-I levels over time expressed in absolute and SDS values(Following 4 and 16 weeks of MOD-4023 treatment)
- Number of IGF-1 normalized patients in stage II(Following 16 weeks of MOD-4023 treatment)
- Change of IGFBP-3 over time expressed in absolute values(Following 4 and 16 weeks of MOD-4023 treatment)
