Titles & IDs
Public title
A randomised cross over pilot study of inhaled tobramycin as a treatment option for hospitalised patients with cystic fibrosis versus standard treatment of intravenous tobramycin
Scientific title
Is inhaled tobramycin as effective as intravenous tobramycin and potentially less toxic for treating acute exacerbations of lung infection in those patients with cystic fibrosis (CF) who are chronically colonised with Pseudomonas aeruginosa?

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Each participant will receive either IV tobramycin at the dose they received on their last admisson (usually 7-10mg/kg) once daily for 14 days or they will receive inhaled tobramycin at a dose of 300mg twice a day for 14 days. Once thier treatment has been completed they will cease these medications and will receive the other arm of the study on their next admission. Their admissions must be a minimum of 6 weeks apart.
Intervention code [1] 3461 0
Treatment: Drugs
Comparator / control treatment
Intravenous tobramycin will be given for 14 days at the same dose as their previous admission. Therapeutic drug monitoring will be carried out to ensure adequate levels are being achieved without increasing the risk of toxicity. On their next admisson they will receive inhaled tobramycin
Control group
Active

Outcomes
Primary outcome [1] 4818 0
Improvement in lung function which will be measured using spirometry. Forced Expiratory Volume in 1 second (FEV1) expressed as % predicted will be compared.
Timepoint [1] 4818 0
Pre-treatment (either in clinic before they are admitted or on their first day of admission), on the last day of their treatment, next clinic appointment (usually 6 weeks after the end of treatment)
Primary outcome [2] 4819 0
Time until need next admission needed by the patient for treatment of an exacerbation of their lung infection
Timepoint [2] 4819 0
Time until their next admission will be recorded in weeks until they are re-admitted for an exacerbation of their lung infection
Primary outcome [3] 4820 0
Alteration in renal function will be measured using urine beta2-microglobulin and serum creatinine (which will also be used to measure creatinine clearance by using equations)
Timepoint [3] 4820 0
Bloods will be taken before they receive their first dose of antibiotics on day 1 of their admission, bloods will also be taken on day 8 of their admission. Urine samples will be taken on the first day of their admission and on day 14 of their admission and then at their next clinic appointment (usually 6 weeks after the end of treatment)
Secondary outcome [1] 8140 0
Weight
Timepoint [1] 8140 0
They will be weighed on day one and day 14 of their admission and then again at their next clinic appointment (usually 6 weeks after the end of treatment)
Secondary outcome [2] 8141 0
Patients perception of how they are feeling using a quality of life questionnaire
Timepoint [2] 8141 0
This will be administered on day 1 and day 14 of their treatment
Secondary outcome [3] 8142 0
Presence or changes in antibiotic resistance patterns to Pseudomonas aeruginosa by sending sputum samples to microbiology were they will test the cultures for sensitivities
Timepoint [3] 8142 0
On day 1 of their admission(unless a sample was collected in clinic before they were admitted), on day 14 of their treatment and at their next clinic appointment (usually 6 weeks after the end of treatment)
