Plain English summary of protocol

Background and study aims
Carbamazepine is a drug used to treat epileptic seizures and nerve pain. The aim of this study is to test if this drug or its components can bind to proteins within the body and can create allergic reactions for people who are genetically prone to such reactions. We aim to find out the levels of the drug carbamazepine and its components following a single dose of carbamazepine.

Who can participate?
Healthy men aged between 18 and 55 years.

What does the study involve?
Participants will be asked to attend the clinical research unit at the Royal Liverpool Hospital. They will screened for suitability to take part in the study. If suitable they will be asked to return for another visit where they will be prescribed a single dose of carbamazepine. Before taking this dose they will be asked to provide a blood sample and then blood samples will be taken at regular intervals up to 72 hours after taking the drug. Urine samples will also be taken during the 72 hours.

What are the possible benefits and risks of participating?
There will be no direct benefits to participants. The risks of participating include pain and bruising associated with blood sampling. We will minimise this risk as only healthcare professionals trained in taking blood samples will be allowed to perform these procedures.

Where is the study run from?
The Royal Liverpool University Hospital (UK).

When is the study starting and how long is it expected to run for?
August 2013 to December 2013.

Who is funding the study?
Medical Research Council (MRC) (UK).
