E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main research question is to find out whether it is possible to carry out a randomised study looking at whether sertraline alone or cognitive behavioural therapy alone or a combination of both sertraline and cognitive behavioural therapy is better in treating obsessive compulsive disorder (OCD). The study will look at what obstacles there are in recruiting into a large trial, the practicality of delivering treatment and the acceptability to patients. Symptom changes, quality of life changes and resource use will also be assessed. |
|
E.2.2 | Secondary objectives of the trial |
Outcome measures will be evaluated. The variation in the Y-BOCS (a specific questionnaire looking at obsessions and compulsions to assess OCD severity) both within and between the three treatment arms will be evaluated. The following outcomes will also be evaluated to assess the influence on patient selection and on the change in Y-BOCS score. This will help inform the need for adjusted and stratified analysis within the large trial. The endpoints will be evaluated to enable appropriate estimation of sample size required for a full-scale trial. -Clinical Global Impression (CGI) Symptom Scale and CGI Improvement Scale (a scale to assess the clinical state of the patient) -Sheehan Disability Scale (a scale to look at how symptoms affect your life) -The Autistic Quotient (a questionnaire looking at autistic traits) -The Montgomery Asberg Depression Rating Scale -CANTAB: Stop signal reaction time; ID-ED; Affective go-no-go; Cambridge gamble task (computerised tasks to look at cogn |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome for the study is to assess the feasibility to inform a larger clinical trial. This will be done by evaluating the number of patients willing to be randomised, evaluating the differences in methods of identifying patients, investigating premature discontinuation rates, evaluating tolerability across treatment arms and assessing resource use and quality of life. Outcome measures will also be evaluated to estimate the sample size required for a large trial. For the outcome measures the primary endpoint is to estimate the variation in the Y-BOCS both within and between the three treatment arms. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The Y-BOCS will be completed at screening, baseline, week 2, week 4, week 8, week 16, week 32 and week 52.
The trial management group will evaluate the progress (patient recruitment, discontinuation rates, tolerability) of the trial on an ongoing basis. |
|
E.5.2 | Secondary end point(s) |
The following outcome measures will be evaluated to assess the influence on patient selection and on the change in Y-BOCS score which will help inform the need for adjusted and stratified analysis within the large trial. -Clinical Global Impression (CGI) Symptom Scale and CGI Improvement Scale -Sheehan Disability Scale -The Autistic Quotient -The Montgomery Asberg Depression Rating Scale -CANTAB: Stop signal reaction time; ID-ED; Affective go-no-go; Cambridge gamble task -CSRI -EQ-5D |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
The SDS and MADRS will be evaluated at baseline, week 2, week 4, week 8, week 16, week 32 and week 52. The CGI symptom scale and AQ will be evaluated only a baseline. The EQ-5D, CSRI and CANTAB will be evaluated at baseline, week 16 and 52. The CGI improvement scale will be evaluated at weeks 2,4, 8, 16, 32 and 52. |
