E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To find best treatment for children and adolescents with OCD who are partial- or non-responders to Cognitive Behavioural Therapy (CBT). CBT (14 session) is the treatment of choice in pediatric OCD. About a third of the patients are non- or partial responders. Non- or partial responders to CBT are randomised (Step 2) to either continued CBT or to Sertraline (with continued CBT support) to find an optimal treatment strategy: an increased "dose" of CBT or medication with Sertraline together with CBT-support. No study has studied SSRI effectiveness in CBT non- or partial responders.

|
E.2.2 | Secondary objectives of the trial |
To identify predictors, moderators and mediators of good and non- or partial Sertraline- respectively CBT response in non- or partial pediatric OCD CBT responders (step2). |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Molecular genetic aspects of Obsessive Compulsive Disorder (OCD) and OCD treatment response: Objective: to identify genetic markers that (1) are characteristic of pediatric OCD patients (trio-design); (2) identify genetic markers that are characteristic of CBT responders and CBT non- or partial responders; (3) identify genetic markers that are characteristic of Sertraline responders respectively non-responders to CBT non- or partial responders.
Magnetkameraundersökning av glutamat/glutamin-koncentrationen i hjärnan vid tvångstillstånd (OCD: Objective: to investigate functional brain abnormalities in pediatric OCD using Magnet resonance spectroscopy (MRS) in parts of the Cortici-Strtiatal. Thamalic-Cortical loops that are believed to be the one where the brain substrate of the OCD symptoms are situated. MRS can be used to identify glutamat concentration of the various parts of this functional loop. Also, substances that are associated with the vitality of components in the loop can be guaged.
Backgroundsfactors and outcome in pediatric OCD: Objective to study various correlates and possible backgroundsfactors in pediatric OCD. Also, evaluating various scales and interviews used in pediatric OCD. The study stated 1/1 2001 and we have published several papers and the naturalistic outcome at 6 and 12 months of a five year cohort.

E.3 | Principal inclusion criteria |
Obsessive Compulsive Disorder according to DSM IV of moderate-severe type in patients aged 7-17. Severity as defined by Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) Scores of 16 or above. All patients included in step 2, involving Sertralin have failed an adequate trial of CBT for 14 sessions (in step 1), i.e. that CY-BOCS scores are still 16 or above.All co-morbidities are allowed except as defined below. |
|
E.4 | Principal exclusion criteria |
patient has been treated with CBT or Sertraline in the last year for OCD. Other psychiatric disorder with higher treatment priority (e.g. acute psychosis, suicidality in major depression, severe Anorexia nervosa). Mental retardation, Autism and Asperger's syndrome. Patient and/or parent does not understand or can speak the language. Comorbidity with ADHD, bipolar disorder etc are allowed if the patient is stabilised on the appropriate drug for at least 3 months. |
|
E.5 End points |
E.5.1 | Primary end point(s) |
CYBOCS scores at 8 weeks and 3 months after inclusion in step 2 respectively step 3. Responder is defined as the patient having reduced their CYBOCS scores to 11-15 points. Excellent response is defined as CY-BOCS scores of 10 or below. Responders will be followed up for up to 36 months (at +6, +12, +24 and +36 months) using the CY-BOCS and the stability of the treatment gains can thus be established. The Clinical Global Impression (CGI) and Clinical global Improvement (CGIimp) will be used at the same timepoints. |

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
Dr Pål Zeiner M.D., Ph.D. , BUP, Drammen, Norway is the trial monitor with full access to data and powers to stop the trial. He is not part of the NordLOTS study or NordLOTS steering group.
If the trial monitor finds that any treatment (i.e. CBT or Sertraline) in step 2 is inferior to the other and no sub-groups have markedly better response in either form of therapy, then the monitor is to stop the trial. |
