Plain English Summary
Background and study aims
People with borderline personality disorder have poor mental health and may experience sudden and distressing changes in mood. No medication is currently licensed to help people with borderline personality disorder and treatment options for patients are therefore limited. Lamotrigine is a mood stabiliser which has been successfully used to help people with mood disorders. The aim of this study is to test whether adding lamotrigine to usual treatment for people with borderline personality disorder improves mental health and is a cost-effective use of resources.
Who can participate?
People aged 18 or over who are in contact with mental health services in England and have a diagnosis of borderline personality disorder.
What does the study involve?
All those who take part in the study receive a full assessment of their mental health, social functioning and use of healthcare services before their entry into the study. All those who take part in the study have three follow-up assessments, 12, 24 and 52 weeks after their entry into the study. Half the study participants are prescribed lamotrigine and the other half are prescribed a placebo (dummy) which is identical in appearance to the lamotigine but does not contain any active drug. All people in the study continue to have access to services including other drug treatments.
What are the possible benefits and risks of participating?
There will be no immediate direct benefit to those taking part, but study participants will be helping make sure that in the future people with borderline personality disorder receive better treatment. There are no risks from taking the part other than people who receive lamotrigine may experience side effects from taking this medication.
Where is the study run from?
The study is run from the Centre for Mental Health at Imperial College London in collaboration with University of Nottingham, Tees, Esk & Wear Valleys NHS Foundation Trust, Kings College London, Central and North West London NHS Foundation Trust, Oxleas NHS Foundation Trust, and Nottinghamshire Healthcare NHS Trust
When is the study starting and how long is it expected to run for?
We will start to recruit study participants in early 2013. Recruitment is due to end in 2015 and the results of the study are due to be published at the end of 2017. Each study participant will be followed-up for at least one year, but the study may be extended for a further period to examine the longer-term impact of the use of lamotrigine on mental health of people with borderline personality disorder.

| Scientific title | The clinical and cost effectiveness of lamotrigine for people with borderline personality disorder: a randomised controlled trial |
| Study acronym | LABILE |
| Study hypothesis | The main aims of the study are: 1. To test whether adding lamotrigine to usual care for adults with borderline personality disorder (BPD) improves mental health over a 52 week period, in comparison to a placebo control. 2. To examine whether the addition of lamotrigine to usual care for adults with BPD improves social functioning and quality of life, reduces the incidence of suicidal behaviour, and lowers the amount of antipsychotic and other psychotropic medication that people are prescribed, in comparison to a placebo control. 3. To compare the incidence of side effects among those prescribed lamotrigine in addition to usual care for adults with BPD, in comparison to a placebo control. 4. To examine the cost, cost-utility and cost-effectiveness of adding lamotrigine to usual care for adults with BPD, in comparison to a placebo control. The primary hypothesis is that the addition of lamotrigine to usual treatment of people with borderline personality disorder who are in contact with mental health services will reduce symptoms of their disorder measured at 12 months using the Zanarini Rating Scale for Borderline Personality Disorder.
