The Effect of GHRH Therapy on Myocardial Structure & Function in

Status Completed

Clinical Trial Summary

PP1- The purpose of this study is to determine whether giving more of the hormone produced by everyone called growth hormone releasing hormone (GHRH) can improve heart function in individuals with congestive heart failure. You must be 50 years old or older, have a diagnosis of congestive heart failure, and have a high likelihood of having lower than normal growth hormone effect. GHRH is approved by the US FDA for treatment in children with growth hormone deficiency because GHRH stimulates Growth Hormone (GH). Its use for treatment of congestive heart failure in adults is investigational.

Growth hormone releasing hormone is a hormone produced in the brain. We will be using synthetic hormone made in the laboratory. It is identical to the hormone in the brain.

Many older people, due to aging have low levels of growth hormone. The aim of this study is to find out whether restoring growth hormone levels to the levels found in younger individuals and then maintaining those levels for 12 weeks will help strengthen heard muscles in older persons with congestive heart failure.

Clinical Trial Description

PP1- The overall purpose of this study is to evaluate the effects of Growth Hormone Releasing Hormone (GHRH) on cardiac structure and function in subjects aged 50 years and older with a diagnosis of congestive heart failure in a single blinded (to the subject) randomized treatment/placebo study design. They will receive 12 weeks of drug or placebo, 6 weeks of washout, and 12 weeks of placebo or drug- whichever they didn't receive in the first 12 weeks. The hypotheses are: 1)normal aging is associated with evidence of declining somatotrophic activity exemplified by IGF-1 levels; 2) GHRH can raise levels of Growth hormone and IGF-1 in elderly individuals in a dose dependent fashion with minimal deleterious side effects; 3) GHRH will produce measurable increments in myocardial performance and structure and demonstrated growth of peripheral musculature; 4) the combination of these benefits will result in better quality of life due to the improvement of overall cardiac function. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
