STaph Aureus Resistance-Treat Early and Repeat (STAR-TER) (STAR-TER)
Cystic Fibrosis
About this trial
This is an interventional treatment trial for Cystic Fibrosis focused on measuring Methicillin-resistant Staphylococcus aureus (MRSA), Early infection, Treatment, Forced Expiratory Volume in 1 Second (FEV1)
Eligibility Criteria
Inclusion Criteria:
- Male or female ≥ 2 and ≤ 45 years of age at the Screening Visit.
Documentation of a CF diagnosis as evidenced by one or more clinical features consistent with the CF phenotype and one or more of the following criteria:
- sweat chloride ≥ 60 milliequivalents/liter by quantitative pilocarpine iontophoresis test (QPIT)
- two well-characterized mutations in the cystic fibrosis transmembrane conductive regulator (CFTR) gene
- abnormal nasal potential difference(NPD) (change in NPD in response to a low chloride solution and isoproteronol of less than -5 mV)
First OR early MRSA colonization defined as:
- First MRSA colonization: first documented isolation of MRSA from respiratory tract occurred ≤ 6 months prior to screening
- Early MRSA colonization: MRSA was previously isolated from the respiratory tract ≤ 2 times over the past 3.5 years, but this was followed by at least 1 year of documented negative cultures for MRSA
- MRSA is available to the central laboratory - either the incident MRSA isolate from the clinic visit or the subject is MRSA positive at the screening visit
- Clinically stable with no significant changes in health status within the 14 days prior to screening
- 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
Exclusion Criteria:
- Received antibiotics with activity against MRSA within 28 days prior to screening
- Use of an investigational agent within 28 days prior to screening
- For subjects ≥ 6 years of age: FEV1 at screening < 25% of predicted for age based on the Wang (males < 18 years, females < 16 years) or Hankinson (males ≥ 18 years, females ≥ 16 years) standardized equations
- MRSA from the screening culture or the most recent clinical care visit within 6 months prior to screening resistant to TMP/SMX
- History of intolerance to topical chlorhexidine or mupirocin
- History of intolerance to both TMP/SMX and minocycline
- < 8 years of age and allergic or intolerant to TMP/SMX
- ≥ 8 years of age and allergic or intolerant to TMP/SMX and MRSA isolate (from screening or clinical care visit)is resistant to minocycline
- For females of child bearing potential: pregnant, breastfeeding, or unwilling to use barrier contraception through Day 42 of the study
Subjects with history of abnormal renal function will need screening labs showing normal function Abnormal renal function is defined as estimated creatinine clearance <50 mL/min using the:
- Bedside Schwartz Equation for subjects <18 years of age, and
- Levey Glomerular filtration rate (GFR) Equation for subjects ≥ 18 years of age.
- Subjects with a history of abnormal liver function will need to have screening labs showing normal transaminases. Liver dysfunction is defined as ≥3x upper limit of normal (ULN), of serum aspartate transaminase (AST) or serum alanine transaminase (ALT) or abnormal synthetic function
- History of solid organ or hematological transplantation
- Presence of a condition or abnormality that in the opinion of the Investigator would compromise the safety of the patient or the quality of the data.

Arms of the Study
Arm 1
Experimental
Treatment
Subjects are treated with one oral antibiotic, one topical antibiotic, an oral rinse, and instructed to use environmental decontamination techniques. Trimethoprim Sulfamethoxazole (TMP/SMX) is the primary oral antibiotic to be used. Subjects with allergy or intolerance to TMP_SMX will use minocycline as an alternative antibiotic. Topical antibiotics are nasal Mupirocin, and the oral rinse/gurgle with 0.12% chlorhexidine gluconate.
