A Pilot Trial of Curcumin Effects on Cognition in Schizophrenia

Status Terminated

Clinical Trial Summary

This is an 8-week randomized, double-blind, placebo-controlled, parallel, fixed-dose pilot clinical trial of curcumin for the treatment of cognitive impairment in schizophrenia.The primary aim of this pilot trial is to provide an effect size estimate for the efficacy of curcumin in improving cognitive functioning in schizophrenia. Secondary goals are to determine the effect of curcumin over time on negative and positive symptoms, in association with inflammatory markers.

Clinical Trial Description

This is an 8-week randomized, double-blind, placebo-controlled, parallel, fixed-dose pilot clinical trial of curcumin for the treatment of cognitive impairment in schizophrenia. Cognitive impairment and persistent negative symptoms are the core dimensions of schizophrenia; however current antipsychotic treatment fails to address this issue. Evidence suggests cognitive impairment is not only limited to patients with late-stage schizophrenia. High rates of cognitive impairment in patients with first episode psychosis indicate that cognitive impairment is not solely a consequence of long-term antipsychotic treatment, but rather is an enduring problem over the course of schizophrenia. Likewise, negative symptoms persist throughout its entire course, and are associated with poor overall functioning. Currently, there are no pharmacological agents that specifically aim to treat cognitive functioning and persistent negative symptoms; therefore, there is growing interest in the development of effective treatments for this unmet need.

The primary aim of this pilot trial is to provide an effect size estimate for the efficacy of curcumin in improving cognitive functioning in schizophrenia. Secondary goals are to determine the effect of curcumin over time on negative and positive symptoms, in association with inflammatory markers. Eligible participants will be randomized to curcumin (n=20) or placebo (n=20) in a 1:1 ratio. A commercially available surface-controlled water soluble form of 600mg curcumin (10% formulation) or matching placebo capsules will be administered three times a day for a total of 8 weeks. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
