  Purpose
Cystic fibrosis (CF) is a lethal genetic condition that affects 30,000 children and adults in the United States. Although CF management has improved substantially over the past two decades, there is still no cure and most patients with CF die before reaching their 50th birthday, largely due to lung failure. There is growing evidence that excess lung and blood inflammation that occurs in response to infections in the lungs cause CF patients to be sicker. Simvastatin is a drug that is used to lower cholesterol, but many researchers have found that this drug may also treat blood and lung inflammation. In this study, we will determine whether or not simvastatin can treat blood and lung inflammation in patients with CF and most importantly determine whether or not it can make these patients feel better and have better lung function.

Primary Outcome Measures:
  • C-reactive protein [ Time Frame: 12 weeks ]
    The difference in the change in plasma C-reactive protein concentrations from baseline to 12 weeks of treatment between those randomized to simvastatin 40 mg/d and those randomized to placebo


Secondary Outcome Measures:
  • Changes in forced expiratory volume in one second (FEV1) [ Time Frame: 12 weeks ]
    The differences in the above parameters over 12 weeks between those assigned to simvastatin 40 mg/d and those assigned to placebo.

  • Changes in exacerbation rates [ Time Frame: 12 weeks ]
    The differences in the above parameters over 12 weeks between those assigned to simvastatin 40 mg/d and those assigned to placebo.

  • Changes in blood pro-inflammatory markers such as IL-6, TNF, IL-1beta, LPS, LBP, sCD14, EndoCAB, SP-D, CCL-18) [ Time Frame: 12 weeks ]
    The differences in the above parameters over 12 weeks between those assigned to simvastatin 40 mg/d and those assigned to placebo.

Detailed Description:

Study Objectives

  1. To determine the effect of 12 weeks of 40 mg once daily simvastatin on general inflammatory molecules, IL-6 and CRP in the blood of CF patients.
  2. To determine the effect of simvastatin on LPS-related pathway molecules in the blood.
  3. To determine the effect of simvastatin on inflammatory pneumo-proteins in the blood.
  4. To determine exacerbation and safety data on statins in preparation for a large phase III trial of statins in CF.

Study Endpoints

The primary endpoint will be the quantitative changes in serum levels of CRP.

Secondary endpoints will include:

  1. blood biomarkers IL6, LPS related proteins, LPS, LBP, sCD14 and EndoCAb, and pneumoproteins, SPD and CCL18; and molecules such as TNF-α and IL-1beta;
  2. changes in FEV1 over 12 weeks ; and
  3. exacerbations over 12 weeks
