Brief Summary:

The prevalence of methicillin resistant Staphylococcus aureus (MRSA) respiratory infection in Cystic Fibrosis (CF) has increased dramatically over the last decade. Evidence suggests that persistent infection with MRSA may result in an increased rate of decline in Forced Expiratory Volume (FEV)1 and shortened survival. Currently there are no conclusive studies demonstrating an effective aggressive treatment protocol for persistent MRSA respiratory infection in CF. Data demonstrating an effective and safe method of clearing persistent MRSA infection are needed.

The purpose of this study is to evaluate the safety and efficacy of a 28-day course of vancomycin for inhalation, 250 mg twice a day, (in combination with oral antibiotics) in eliminating MRSA from the respiratory tract of individuals with CF and persistent MRSA infection. Subjects will be assigned in a 1:1 ratio to either vancomycin for inhalation (250 mg twice a day) or taste matched placebo and will be followed for 3 additional months. In addition, both groups will receive oral rifampin, a second oral antibiotic (TMP-SMX or doxycycline, protocol determined), mupirocin intranasal cream and chlorhexidine body washes. Forty patients with persistent respiratory tract MRSA infection will be enrolled in this trial.

Primary Outcome Measures :
  1. Number of Patients MRSA Free by Induced Sputum Respiratory Tract Culture [ Time Frame: Day 58 (Visit 5), approximately 1 month after completion of the MRSA treatment protocol ]
    The hypothesis for our primary outcome is that the aggressive treatment arm will result in significantly greater eradication of persistent MRSA from the respiratory tract of CF adolescents and adults on day 58 (1 month after completion of therapy) compared to the placebo/standard treatment arm. Our primary outcome will be comparing the proportion of CF patients in the treatment arm who have a negative induced sputum MRSA culture at Day 58 to the proportion of patients in the placebo arm who have a negative induced sputum MRSA culture at Day 58.


Secondary Outcome Measures :
  1. Percentage of Patients MRSA Free by Induced Sputum Respiratory Tract Culture [ Time Frame: Day 29 ]
    Percentage of patients MRSA free by induced sputum respiratory tract culture one day after completion of four-week eradication protocol (Day 29) in intervention arm vs standard treatment arm

  2. Change in Forced Expiratory Volume (FEV1)% Predicted From Baseline to Day 58 [ Time Frame: Baseline, Day 58 ]
    Change in Forced Expiratory Volume (FEV1)% predicted from baseline to day number 58

  3. Time to First CF Exacerbation [ Time Frame: Day 1 to Day 118 ]
    Time to First CF Exacerbation using a standardized exacerbation definition from Day 1 to Day 118

  4. Total Number of Pulmonary Exacerbations [ Time Frame: Days 58 and 118 ]
    Total Number of Pulmonary Exacerbations using a standardized exacerbation definition at Days 58 and Days 118 in treatment vs. standard care group

  5. Change if FEV1% Predicted From Screening [ Time Frame: Days 29, 58, and 118 ]
    Change in FEV1% predicted from Screening at Days 29, 58, and 118 in treatment vs. standard care group

  6. Change in Patient Reported Quality of Life (CFQ-R)(Respiratory) [ Time Frame: Days 29 and 58 ]
    Change in Patient Reported Quality of Life (CFQ-R)(respiratory) from baseline to Days 29 and 58. CFQ-R stands for Cystic Fibrosis Quality of Life Measure, Respiratory Domain. Overall range of absolute score 0 to +80. Higher score means better quality of life. Positive change in score means improvement in quality of life. Minimally clinically significant difference: +/- 4.0 units.

  7. Development of Antibiotic Resistance [ Time Frame: Day 58 (Visit 5) ]
    Number of patients with newly developed MRSA resistance to vancomycin, TMP/SMX, doxycycline, or rifampin.

  2. Confirmed diagnosis of CF based on the following criteria:

    positive sweat chloride > 60 mEq/liter (by pilocarpine iontophoresis) and/or a genotype with two identifiable mutations consistent with CF or abnormal Nasal Potential Difference (NPD), and one or more clinical features consistent with the CF phenotype.

  3. Written informed consent (and assent when applicable) obtained from subject or subject's legal representative and ability for subject to comply with the requirements of the study.
  4. Two positive MRSA respiratory cultures in the last two years at least six months apart, plus a positive MRSA respiratory culture at Screening Visit and Run-in (Day -14) Visit.
  5. At least 50% of respiratory cultures from the time of the first MRSA culture (in the last two years) have been positive for MRSA.
  6. Forced Expiratory Volume (FEV)1 > 40% of predicted normal for age, gender, and height at Screening, for subjects 18 years of age or older..
  7. FEV1> 60% of predicted normal for age, gender, and height at Screening, for subjects 12--17 years of old.
  8. Females of childbearing potential must agree to practice one highly effective method of birth control, including abstinence. Note: highly effective methods of birth control are those, alone or in combination, that result in a failure rate less than 1% per year when used consistently and correctly. Female patients who utilize hormonal contraceptives as a birth control method must have used the same method for at least 3 months before study dosing. If the patient is using a hormonal form of contraception, patients will be required to also use barrier contraceptives as rifampin can affect the reliability of hormone therapy. Barrier contraceptives such as male condom or diaphragm are acceptable if used in combination with spermicides

  2. Individuals on chronic continuous inhaled antibiotics without interruption who are not willing to substitute vancomycin or placebo for their scheduled inhaled antibiotic during days 0-28 of the study (every other month inhaled antibiotics are acceptable)
  3. Use of oral or inhaled anti-MRSA drugs within two weeks of the Screening Visit.
  4. History of intolerance to inhaled vancomycin or inhaled albuterol.
  5. History of intolerance to rifampin or both TMP/SMX and doxycycline.
  6. Resistance to rifampin or both TMP/SMX and doxycycline at Screening.

  10. Serum hematology or chemistry results which in the judgment of the investigator would interfere with completion of the study.
  11. History of or listed for solid organ or hematological transplantation
  12. History of sputum culture with non-tuberculous Mycobacteria in the last 6 months.
  13. History of sputum culture with Burkholderia Cepacia in the last year.

  16. Administration of any investigational drug or device within 28 days of Screening or within 6 half-lives of the investigational drug (whichever is longer).
  17. Patients on inhaled antibiotics must have been on the same regimen for the 4 months prior to screening
