Plain English Summary

Background and study aims
Cystic fibrosis is a genetic condition where the lungs and digestive system gets clogged with thick sticky mucus. Many children with cystic fibrosis (CF) have treatment with an antibiotic called tobramycin given straight into the blood stream (called intravenous or IV). This helps treat their lung infections, but it can sometimes cause kidney problems. We think that giving a medicine called rosuvastatin at the same time as tobramycin could help protect the kidneys from damage and make it safer to give tobramycin. To help us find out whether this is true or not, we are doing a research study called a clinical trial in children with CF getting IV tobramycin where half of the children taking part also get rosuvastatin, and the other half do not.

Who can participate?
Children aged 10 to 18 years with cystic fibrosis.

What does the study involve?
At the first visit each child will be randomly allocated to their treatment group for the study. There is an equal chance of being in either group. One group will take a rosuvastatin tablet each day they are having IV tobramycin, and the other group will just have their IV tobramycin as normal. Each child will be in the study for about 6 weeks and will normally have five visits as part of the study. As much as possible we will do the study visits and blood tests at the same time as they would normally have them. However, the study will usually mean having two more blood tests and visits than normal, and we will take a little more blood than usual each time. There will be study visits on the day of starting IV tobramycin, on three further occasions during the course of treatment (usually 14 days), and 4 weeks after completing treatment. In addition, daily urine samples will be collected during the course of tobramycin.

What are the possible benefits and risks of participating?
Like any medicine, rosuvastatin can have side effects. Rarely, it can have serious effects on the liver or muscles. These, and other possible side effects, will be explained to potential participants before agreeing to the study. We will monitor each child very closely for any side effects during the study. If the study shows that rosuvastatin does protect the kidneys, then there may be a benefit to the children who take part, and the study may help children and young people in the future. However, we will not be able to continue prescribing rosuvastatin at the end of the study, even if they have benefitted from it.

Where is the study run from?
The study is run by the University of Liverpool and University College London, and will be recruiting participants at the following hospitals in the UK: Alder Hey Children’s Hospital, Liverpool, Great Ormond Street Hospital, Nottingham Children’s Hospital, and Bristol Royal Hospital for Children.

When is the study starting and how long is it expected to run for?
October 2014 to September 2016.

Who is funding the study?
The JP Moulton Charitable Foundation (UK).

Topic: Children; Subtopic: All Diagnoses; Disease: All Diseases


Patients will be randomised equally to either receive rosuvastatin 10 mg once daily or no intervention (control), throughout a course of treatment with IV tobramycin (usually lasting 14 days).

Study visits will be conducted on the day of starting IV tobramycin, on three further occasions during the course of treatment (usually 14 days), and 4 weeks after completing treatment. In addition, daily urine samples will be collected during the course of tobramycin.

Intervention type



Phase II

Drug names

Primary outcome measure

Mean fold-change in urinary KIM-1; Timepoint(s): Urinary KIM-1 measured daily during tobramycin exposure. This will be assessed using the difference in mean fold-change in urinary KIM-1 from baseline to peak concentration during exposure to tobramycin between the rosuvastatin-treated arm and control arm.
