NCT05681299

Brief Summary

This is a randomized, placebo-controlled, cross-over study with 4 arms. Healthy and GH deficient adults ages 18-45 years will be studied. Arms will consist of 21-day treatment periods and be separated by 8-week washout periods. Subjects will receive, in random order: i) GH alone, ii) GH with liraglutide, iii) liraglutide alone and iv) placebo. Each phase of the study will consist of a 7-day baseline period including 2 days of testing and 21 days on therapy with visits on days 2, 7, 14 and 21. Testing before, during and at the completion of each arm will include blood sampling and assessments of insulin resistance, energy expenditure and body composition.

Outcome Measures

Primary Outcomes (2)

  • AgRP change in GH vs. placebo arms

    Difference in percent change in morning fasting level of AgRP (agouti-related peptide) in plasma in GH vs. placebo arms.

    Baseline to weeks 1, 2, 3 of each study arm.

  • AgRP change in GH vs. GH + liraglutide arms

    Difference in percent change in morning fasting level of AgRP in plasma in GH vs. GH+liraglutide arms.

    Baseline to weeks 1, 2, 3 of each study arm.

Secondary Outcomes (2)

  • AgRP change in GH arm

    Baseline to week 1,2, 3 of study arm.

  • AgRP change in liraglutide vs. placebo arms

    Baseline to weeks 1,2, 3 of each study arm

Study Arms (4)

Growth hormone

ACTIVE COMPARATOR

GH will be administered as one nightly subcutaneous self-injection at 11pm at a dose of 0.03 mg/kg/day in healthy and 0.5 mg in male and 0.6 mg in female GHD subjects. Injections will be performed from the night of day 0 to the night of day 20.

Drug: growth hormone

Liraglutide

ACTIVE COMPARATOR

Liraglutide will be administered by subcutaneous injection taken by subjects beginning at a dose at 0.6 mg nightly from 9-11 pm and escalated in 0.6 mg increments weekly as tolerated to a final dose of 1.8 mg nightly. Injections will be performed from the night of day 0 to the night of day 20.

Drug: liraglutide

Growth hormone and liraglutide
