About this study

Official title: An Long Term Trial on Effectiveness and Safety of Atypical Antipsychotic Agents in Augmenting SSRI-Refractory Obsessive-Compulsive Disorder

Objective: Although atypical antipsychotic drugs (AAPDs) have been found effective in the augmentation of serotonin reuptake inhibitors (SRIs) for treatment-resistant obsessive-compulsive disorder (OCD) in short terms trials, there are few data on the effectiveness and safety of these agents in clinical settings over the long term.

Method: Subjects (n=46) who responded to selective SRIs (SSRIs) in an initial 12-week trial were continued on SRI-monotherapy plus cognitive-behavioral therapy (CBT) for one year. Subjects (n=44) who failed to respond to SSRIs were randomly assigned to one of 3 AAPDs such as risperidone and were consecutively treated using SSRI+AAPD combined with CBT for a year.

Read the detailed description

More recently, second-generation atypical antipsychotic drugs (AAPD) that modulate both 5-HT and DA function, such as risperidone (RIS), olanzapine (OLZ) and quetiapine (QET), have been found effective in the augmentation of SSRIs for treatment-resistant OCD.

Nevertheless, the AAPDs have been associated with common and serious adverse effects, such as body weight (BW) gain and metabolic dysregulation. Metabolic dysregulation includes glucoregulatory dysfunction and dyslipidemia. Indeed, studies of some AAPD in SSRI-refractory OCD patients have similarly reported significant BW gain. AAPD-induced BW gain may influence patients' adherence to medication and places them at risk for a broad range of medical problems.

Most work on AAPDs in treatment-refractory OCD has been conducted in the form of short-term efficacy studies. There have been fewer studies of the effectiveness, safety, and tolerability of these agents in the context of a clinic where CBT is also provided, and where treatment is continued for a significant period of time. In the current effectiveness study, we sought to examine the response of SSRI-refractory patients to augmentation with AAPDs, comparing adverse events in such compared to a control group of SSRI responders.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • atypical antipsychotic drugDrug

    For SSRI-refractory group, either atypical antipsychotic such as mean doses of RIS (3.1±1.9mg/day), of OLZ (5.1±3.2mg/day), and of QET (60.0±37.3mg/day) was added on ongoing SSRI(Paroxetine, Fluvoxamine).

  • exposure response preventionBehavioural

    After at least 12 weeks from treatment initiation, cognitive-behavioral therapy (CBT) using exposure and response prevention was added with psychoeducational interventions and behavioral analysis.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing atypical antipsychotic drug and exposure response prevention in people with SSRI-Refractory Obsessive-Compulsive Disorder, run by Osaka City University at 1 site in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Mar 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Yale-Brown Obsessive-Compulsive Scale (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00854919, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Mar 2009.
