E.2.1 | Main objective of the trial |
The primary objective is to test the hypothesis that, after at least 16 weeks of daily administration (4 for titration, 12 of relatively stable dose, 4 of which at fixed doses, (Study Period 1), risperidone given orally in a dose of 0.25 – 3.0 mg/d depending on body weight (eq. to approximately 0.01 – 0.04 mg/kg/d) is superior to placebo in preventing relapse of symptoms of CD, as assessed through a 12 week, double-blind discontinuation trial (Study Period 2) of children and adolescents not developmentally delayed/mentally retarded, and measured by comparison with mean change from the double-blind baseline to endpoint on the Nisonger Child Behavior Rating Form (CBRF) - Typical IQ Version-ODD/CD disruptive behavior (DBD) Composite Total score (Aman et al., 2008) using investigator-ratings based on all available information.
|
|
E.2.2 | Secondary objectives of the trial |
To establish the long-term efficacy of treatment with risperidone, measuring mean change from the double-blind baseline to endpoint on the pivotal (Nisonger) scale between risperidone and placebo.
To test the effect of risperidone compared to placebo on various behavioural domains following seven months of daily administration of risperidone assessed in a 12‐week, double‐blind discontinuation trial.
To compare changes (impairment) in neurocognitive function following risperidone, assessed in both the 16 weeks open label and the 12-week, double-blind discontinuation trial.
To assess the effect of risperidone compared to placebo on comorbid ADHD symptoms following seven months of daily administration of risperidone assessed in a 12-week, double-blind discontinuation trial.
To compare safety and tolerability results for risperidone and placebo in children and adolescents with CD over 12 weeks of double-blind treatment.

A Randomized Double-Blind, Placebo-Controlled Study of Risperidone in the Treatment of DSM-IV-TR Conduct Disorder in Children and Adolescents.
Date 01-04-2012
The primary objective of this study is to test the hypothesis that risperidone given orally in a dose of 0.25 – 3.0 mg/d depending on body weight (eq. to approximately 0.01 – 0.04 mg/kg/d) for 12 weeks is superior to placebo in reducing disruptive behavioural symptoms associated with DSM-IV-TR defined Conduct Disorder (CD) in the treatment of in- and outpatient children and adolescents (5;0 - < 17;9 y.) not developmentally delayed/mentally retarded, as measured by last-observation-carried-forward (LOCF) mean change from baseline to endpoint on the pivotal scale, the Nisonger Child Behavior Rating Form (CBRF) - Typical IQ Version-ODD/CD disruptive behavior (DBD) Composite Total score (Aman et al., 2008) using investigator-ratings based on all available information. |

E.3 | Principal inclusion criteria |
Patients are eligible to be included in the study only if they meet all of the inclusion criteria below.
[1] Patients (male or female) must be at least 5 years of age, and not more than 17 years and 5 months of age at Visit 1.
[2] Patients must meet DSM-IV-TR diagnostic criteria for DSM-IV CD (312.xx) as confirmed by the Kiddie-SADS, Conduct Disorder Module (Kaufman et al., 1996).
[3] Patients must have an IQ of > 85, measured by 4 subtests (2 verbal plus 2 performance tests) from the Wechsler IQ Scales, (e.g. WISC; WAIS; assessed within < 2 y. before or at study entry), e.g. vocabulary, similarities, block design, and matrix reasoning (cf. Crawford et al., 2010). Age- and country-specific adaptations may be used (detailed instructions may be provided in a respective extra document)
[4] Patients must score ≥ 27 on the Nisonger CBR Form, ODD/CD Disruptive Behavior Composite (D-Total) at baseline (Visit 1 or 2).
[5] Patients must score ≥ 4 (“moderately ill” or “markedly ill”) on the CGI-S rating scale at both baseline measures (visit 1 and 2).
[6] Patients must have a body weight comprised between 5th and 95th percentile based on WHO Body Mass Index for age-sex specific charts, at study entry.
[7] Patients must be able to swallow the study drug.
[8] Patients must have venous access sufficient to allow blood sampling and are compliant with blood draws as per protocol.
[9] If the patient is a female with child-bearing potential, she must test negative for pregnancy (based on a urine pregnancy test) at the time of enrollment and agree to use a reliable method of birth control. Adequate contraception includes: oral contraceptives, intraueterine devices; double barrier method (diaphragm or condom plus spermicide, Norplant™ or Depot Provera™).
[10] Laboratory results, including serum chemistries, hematology and urinalysis, show no significant abnormalities (significant would include laboratory deviations requiring acute medical intervention or further medical evaluation) and there is no clinical information that, in the judgment of a physician, should preclude a patient’s participation at study entry.
[11] All patients must have an ECG at Visit 1 or 2. Results must be available prior to dispensing drug at Visit 3. If an ECG shows any severe abnormality, the patient must be excluded from the study. Patients with other abnormalities may be included at the discretion of the investigator.
[12] Educational level and degree of understanding so that the patients and parents (or legal representative) can communicate suitably with the investigator and study coordinator.
[13] Subjects’ parents/legal guardians must provide and sign informed consent documents; patients must provide informed consent, and sign consent or assent documents if capable, according to the legal requirements in the very country. A reliable person (primary caregiver, parent) must be available to ensure compliance with study procedures throughout the course of the study.
[14] Patients meeting criteria for comorbid ADHD (as to the clinical judgement of the investigator) will not be excluded from study participation.
|
|
E.4 | Principal exclusion criteria |
A patient will be excluded from the study if he or she meets any exclusion criterion described below.
[1] An immediate family member of the patient is professionally affiliated to the investigator site. Immediate family is defined as a spouse, parent, child, or sibling, whether biological or legally adopted.
[2] Has previously completed or withdrawn from this study or has been previously identified as being a non-responder or intolerant of risperidone.
[3] Has been treated within 14 days before Visit 1 with a drug that has not received regulatory approval for any indication at the time of study entry, or has participated in any investigational drug trial within six months prior to baseline (visit 1).
[4] Has a current (within 6 months of the start of the study) or lifetime DSM-IV diagnosis of schizophrenia-related disorders, schizophrenia, bipolar disorder, major depressive disorder or a current substance dependence disorder (given the nature of the study population substance misuse or abuse is not exlusionary), pervasive developmental disorder (autistic disorder or Asperger disorder).
[5] In the clinical judgment of the investigator, currently meets criteria for a primary psychiatric disorder, e.g., Anxiety Disorder, Depressive Disorder, Tic Disorder or Tourette’s Syndrome (comorbid ADHD is permitted, cf. Incl. criteria section).
[6] Starts any psychotropic medication, including health-food supplements that the investigator feels could have central nervous system activity (for example, St. John’s Wort, melatonin), during the course of the study, or is taking any other excluded concomitant medication(s) specified in Section 5.7). (An ongoing long-term medication, e.g., to treat a comorbid disorder such as ADHD, is permitted as long as compound and dose are not changed throughout the course of the study).
[7] Has a history of hypersensitivity to neuroleptics, of tardive dyskinesia, or neuroleptic malignant syndrome.
[8] Has any acute or unstable medical condition, physiological condition, clinically significant laboratory, or ECG results that, in the opinion of the investigator, would compromise participation in the study.
[9] Has a known or suspected seizure disorder.
[10] Female patients who are pregnant or breastfeeding.
[11] Patients with a history of severe allergies to more than 1 class of medications or multiple adverse drug reactions.

E.5 End points |
E.5.1 | Primary end point(s) |
Clinical response is defined as > 25 % reduction from baseline score on the Nisonger CBRF-TIQ D-Total subscale at endpoint (based on a personal communication of the scale author, Dr. Michael Aman, June 2010) and a score of 1 or 2 (“much” or very much” improved) on the CGI-Improvement scale.
The primary efficacy measure will be comparison of the number of days from randomization to relapse for each treatment group using the Kaplan-Meier product limit estimator. Relapse is defined as a deterioration of > 2 points on the CGI-Severity scale and a 25% increase in the score on the Nisonger CBRF-TIQ D-Total compared to start of Study Period II (average of Visits 7 an 8), for at least two consecutive visits, 6–8 days apart (Reyes et al., 2006).
The Clinical Global Impressions-Severity (CGI-S) is a single-item rating of the clinician’s assessment of the severity of symptoms in relation to the clinician’s total experience with CD patients (Guy, 1976; NIMH, 1985). Severity is rated on a 7-point scale (1 = normal, not at all ill; 7 = among the most extremely ill subjects).
Relapse is defined also as a CGI-S worsening of > than 2 points.
