Plain English Summary
Background and study aims
Fluoxetine is an effective and safe drug which has been successfully used for many years to relieve depression. There is now also evidence from small trials that fluoxetine might have other effects on the brain e.g. generation of new brain cells, which might help patients make a better recovery from the physical effects of their stroke. For example, a recent small trial from France suggested that fluoxetine might improve the recovery of strength in stroke patients with residual arm weakness. The aim of this trial is to find out whether fluoxetine, given for 6 months, improves recovery if started in stroke patients who are between 2 and 15 days after their stroke.
Who can participate?
Stroke patients who had a stroke between 2 and 15 days previously can participate, providing they are at least 18 years of age, have had a brain scan that is compatible with a stroke (either due to a bleed or a blood clot in the brain), and still have some residual problems caused by the stroke e.g. weakness in the arm or leg. Stroke patients cannot participate if they are taking medication that might interact with fluoxetine, e.g. a selective serotonin reuptake inhibitor (a type of antidepressant), or if they have had seizures in the past or if they are seriously ill with other medical problems.
What does the study involve?
Researchers will collect information about the type of stroke the patients have had. Then, half the patients will be randomly allocated to fluoxetine capsules for 6 months, and the other half to an identical 'placebo' capsule for 6 months. At hospital discharge, or at 1 month for patients who did not require hospital admission, the researchers will check whether participants are still taking the trial capsules and whether they have experienced any adverse effects. At 3 months, the researchers will contact the participants to check whether they are still taking the capsules, and ask about adverse effects. At six and 12 months after recruitment, participants will be asked to complete questionnaires about their overall recovery from the stroke, and about common problems after stroke e.g. weakness in limbs, memory problems, problems with speech, low mood. These questionnaires can be completed on paper, via the secure trial website or by telephone. If patients cannot complete the forms themselves, their next of kin or carer will be asked to do this. General practitioners will also be contacted at 6 months and 12 months to enquire about any medical problems and use of health care resources e.g. attendance at hospital, new medications. Patients' involvement will end 12 months after recruitment. The researchers will collect data on long-term recovery through national statistics.
What are the possible benefits and risks of participating?
If fluoxetine improves recovery from stroke, those patients allocated fluoxetine may have benefited. However, fluoxetine may have side effects and it may not improve recovery from stroke.
Where is the study run from?
University of Edinburgh and NHS Lothian (UK)
When is the study starting and how long is it expected to run for?
The study will start recruiting patients in July 2012, and will recruit for about four years. Patients will be followed up for 1 year. The study is likely to end in October 2017.
