Risperidone vs. Olanzapine as add-on Treatment in Treatment Resistant Depression

Detailed Description
Overview of Study Design
This is a Canadian, multicentre, double blind, comparator trial in 42 patients with TRD. TRD is defined as the failure to respond adequately to two successive courses of different antidepressants at an adequate dose (at least fluoxetine 20 mg, citalopram 20 mg, paroxetine 20 mg, sertraline 100 mg, fluvoxamine 150 mg, venlafaxine 225 mg)) for at least 4 weeks. All subjects, at entry to the study will be currently not responding to treatment of at least 4 weeks duration of a serotonin re-uptake inhibitor (SSRI) or a selective nor-epinephrine and serotonin re-uptake inhibitor (SNRI). Non-response is defined as a score of 3 ("minimal improvement") or worse on the Clinical global Impression of Improvement .
The objective is to assess the appropriateness of the trial design and to determine sample size requirements for future controlled trials. In addition the efficacy and safety of oral doses of risperidone (.5-3 mg/day) and olanzapine (2.5-15 mg.day) as add-on therapy to any SSRI or SNRI in treatment resistant depression will be evaluated. Subjects meeting the screening criteria will enter a 6-week trial with risperidone or olanzapine added on to the current SSRI or SNRI therapy.
A medical/ psychiatric history, HAM-D-29 (only the first 17 items will be used for outcome), MADRS and HAM-A will be obtained at screening. At subsequent visits HAM-D, HAM-A, and MADRS will be performed and adverse events (spontaneous and using the CASES checklist) and concomitant medications will be collected.
Recruitment:
Subjects will drawn from two sources:
- Outpatients currently attending the clinic at the sites. These subjects will already be in treatment or may have been referred from the local communities of the clinics involved in this study for consultation. Should these subjects drop out or once they have completed the study they will receive the treatment as usual at each site.
- Advertisements. Advertisements will be placed in local media (radio, television, newspaper) identifying the nature of the study and providing a contact number. These advertisements will be approved by the local IRB's prior to posting.

Description
Inclusion Criteria:
Subjects who meet all of the following criteria are eligible for this trial:
- Male or female out-patients;
- Aged between 18 and 65 years (extremes included);
- Subjects suffering from a current episode of non-psychotic, unipolar depression as determined by the depression section of the SCID-IV.
- Subjects with treatment resistant depression defined as failure to respond to two successive courses of monotherapy given in adequate doses for a minimum of 4 weeks with different antidepressants (the current course of antidepressant can be considered to second failed course) and;
- Subjects currently taking a SSRI or a SNRI for at least 4 weeks, at adequate dosage and not responding, as defined by a score of 3 or more on the CGI-I. and no dose change for 2 weeks prior to entry.
- A minimum score of 16 on the 17 item HAM-D
- Ability to provide informed consent.
Exclusion Criteria:
Subjects meeting one or more of the following criteria cannot be selected:
- Subjects who are actively suicidal as determined by a score of 3 on the suicide item on the HAM-D or in the opinion of the treating physician;
- Other current (active symptomatology within the last 2 months) Axis I DSM IV diagnosis other than nicotine or caffeine dependence or other than an Anxiety disorder.
- Use of disallowed concomitant therapy; or other psychotropic medication except occasional benzodiazepines. (See "Rescue Medication");
- History of alcohol or drug abuse or dependence, within 3 months of entry into the trial);
- Seizure disorder requiring medication;
- Active medical condition that requires urgent attention or that would contra-indicate the use of risperidone or olanzapine. For example stable thyroid disease or asthma would be acceptable, whereas acute hepatitis would not;
- Participation in an investigational drug trial within 30 days prior to the start of the trial
- Known sensitivity to risperidone, olanzapine or the antidepressant;
- History of neuroleptic malignant syndrome (NMS);
- Subjects who are at imminent risk of injury to self or others, or causing significant damage to property, as judged by the investigator;
- Female subjects who are pregnant or breast-feeding;
- Female subject of childbearing potential without adequate contraception (sterilization, barrier, IUD, oral contraceptives, intramuscular or subdermal administration of depot-progestagens);
15. Previous exposure to risperidone or olanzapine during the current episode.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Risperidone
Commence at 0.5 mg once daily Increase, blindly, to 1 mg and then by 1 mg at discretion of clinicians through weeks 1-4 to a maximum of 3 mg.
|
Risperidone will commence at 0.5 mg per day in a single daily dose given once in the evening.
Clinicians will have the option, at each visit of increasing the risperidone dose to a maximum of 3 mg/day based on subject response and tolerability (please see Titration Recommendations below).
|
Experimental: Olanzapine
Commence at 2.5 mg once daily Increase to 5.0 mg, blindly, and then by 5 mg at the discretion of the clinician through weeks 1 - 4 to a maximum of 15 mg
|
Olanzapine will commence at 2.5 mg per day in a single daily dose given once in the evening.
Clinicians will have the option, at each visit, of increasing the olanzapine dose to a maximum of 15 mg/day based on subject response and tolerability.
