A Study of the Effectiveness and Safety of Risperidone to Augment SSRI Therapy in Patients With Treatment-resistant Depression

May 17, 2011 updated by: Johnson & Johnson Pharmaceutical Research & Development, L.L.C.

A Study to Evaluate the Efficacy, Safety and Maintenance Effect of Risperidone Augmentation of SSRI Monotherapy in Young and Older Adult Patients With Unipolar Treatment-Resistant Depression

The purpose of this study is to evaluate the effectiveness and safety of risperidone to augment SSRI therapy in patients with treatment-resistant depression and to demonstrate the long-term maintenance effect of risperidone as augmentation therapy compared with placebo augmentation in these patients.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Treatment strategies for treatment-resistant depression (TRD) involve either switching to another antidepressant, augmenting the first-line treatment with various pharmacologic agents, or switching to a different medication in combination with another agent. This study includes 2 phases: an open-label treatment phase and a double-blind maintenance phase, during which neither the patient nor the physician knows whether risperidone or placebo is administered. The open-label phase has an initial period of 6 weeks during which patients with TRD receive only citalopram, a selective serotonin reuptake inhibitor (SSRI). Risperidone is then added to the treatment regimen for 4 weeks to evaluate its short-term effect in augmenting the therapy. The double-blind phase last for 6 months and evaluates the relapse prevention of continued risperidone augmentation therapy compared with placebo augmentation of the SSRI. Targeted daily doses of citalopram and risperidone are adjusted for younger adults (18 to 54 years of age) and older adults (55 to 85 years of age). Assessments of effectiveness include the Montgomery-Asberg Depression Rating Scale (MADRS); Hamilton Rating Scale of Depression (HAM-D); Clinical Global Impression of Severity (CGI-S); response rate, determined by the proportion of patients showing >=50% improvement on MADRS total score; and relapse, evaluated by changes in CGI or HAM-D scores. Safety evaluations include the incidence of adverse events throughout the study, vital signs (pulse and blood pressure) and weight, and clinical laboratory tests (hematology, biochemistry, urinalysis) at specified intervals. The study hypothesis is that risperidone augmentation of SSRI therapy will show significant improvement in symptoms of depression compared with SSRI monotherapy and that risperidone augmentation will show better time-to-relapse than placebo augmentation in patients with TRD. Once daily, oral tablets of risperidone (0.25 milligram[mg], 0.5mg, 1.0mg, and 2.0mg), citalopram (20mg and 40mg) or placebo. Risperidone for 30 weeks; 0.25-2.0mg for younger adults, 0.25-1.0mg for older adults. Citalopram for 36 weeks; 20-60 mg for younger adults; 20-40 mg for older adults.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
258

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Change from baseline in Montgomery-Asberg Depression Rating Scale (MADRS) total score at end of treatment; time to relapse

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Response rate, determined from >=50% improvement from baseline at MADRS total score; change from baseline in Hamilton Rating Scale of Depression (HAM-D) and Clinical Global Impression (CGI) scale; incidence of adverse events throughout study.
