Detailed Description:

With development and progression of chronic kidney disease (CKD) to end stage renal disease (ESRD), malnutrition becomes an increasingly severe problem. This is thought to occur from two mechanisms: decreased appetite secondary to uremia and development of a catabolic inflammatory milieu. Patients experience decreased muscle mass and functional activity associated with increased morbidity and mortality. Many therapies to improve poor nutritional state have been used with little success. Growth hormone (GH) and insulin like growth hormone (IGF-1) improve muscle mass, quality of life, nutritional parameters, immune and physical functions but must be given parenterally and are limited by expense and patient compliance. Recently, the endogenous GH receptor secretagogue (GHRS) ghrelin has been shown to raise endogenous GH and improve food intake but must be given parenterally and is not available. The experimental drug MK-0677, a synthetic GHRS, ghrelin mimetic, which is given orally, has recently been shown to increase IGF-1 and muscle mass in the elderly. Its effects in CKD and ESRD are unknown. We will study the effects of MK-0677 on renal patients. Specifically, we hope to show that the drug increases IGF-1 in renal patients, and has similar effects to exogenous GH and IGF-1. Subjects will be ESRD hemodialysis patients. This protocol is an investigator-initiated, randomized, double-blind crossover, placebo-controlled pilot study. The study's primary outcome is IGF-1 levels for subjects. Secondary outcomes will be levels of cytokines, esterase, leptin, insulin, ghrelin, TNF-alpha, CRPs, IL-1, IL-6, IL-10, and adiponectin.

(The previous use, or current use, of a topical or inhaled corticosteroid is allowed.)
  • Currently taking or previously on an anabolic steroid or growth hormone at any dose, or for any duration, during the 12 months prior to study entry.

  • Any of the following disorders within 6 months prior to baseline:

    1. Acute coronary syndrome (e.g., myocardial infarction or unstable angina)
    2. Coronary artery intervention (e.g., coronary bypass graft [CABG], percutaneous transluminal coronary angioplasty [PTCA]).
    3. Stroke or transient ischemic neurological disorder (e.g. transient ischemic attack [TIA])
  • New or worsening signs or symptoms of coronary heart disease within the 3 months prior to baseline.

  • Active carpal tunnel syndrome
  • Patient is, in the opinion of the investigator, mentally or legally incapacitated such that informed consent cannot be obtained or such that adherence to the study procedures and dosing regimens is questionable.
  • Patient is, at study entry, a regular user (including "recreational use") of illicit drugs or had a recent history (within the last 5 years) of drug or alcohol abuse.
  • Patient plans to relocate or change to a different dialysis center during the study, rendering follow-up per protocol, impractical.
