Sensoril(Ashwaganhda)for Bipolar Disorder

March 14, 2016 updated by: K.N. Roy Chengappa, University of Pittsburgh

Sensoril® (Ashwagandha) - A Standardized Extract From a Medicinal Plant - (Withania Somnifera) for Cognitive Enhancement in Persons With Bipolar Disorder: A Parallel Group, Randomized Double Blind, and Placebo Controlled Study

The investigators hypothesis is that oral Sensoril® (as compared to placebo) will enhance cognitive abilities (specifically measures of attention, executive function, working memory, and visuospatial ability) in persons with bipolar disorder. Secondarily, the investigators hypothesize there will be secondary improvements in residual mood/anxiety symptoms, and metabolic indices, if impaired (fasting blood glucose and lipids).

The investigators aim to test these hypotheses by conducting a randomized, placebo controlled, add on treatment trial of Sensoril® (added to existing mood stabilizer treatment) recruiting 60 subjects with DSM IV-TR bipolar disorder for a period of 8 weeks. Measures of cognition, psychopathology and laboratory indices will be utilized for evaluating primary and secondary outcomes, along with safety assessments.

Study Overview

Detailed Description

OBJECTIVE:

To evaluate if Sensoril® treatment of persons with bipolar illness will improve their cognitive performance and if it will improve residual mood/anxiety symptoms and impaired metabolic indices.

RESEARCH PLAN:

We will conduct a randomized, placebo controlled, add on treatment trial of Sensoril® (added to ongoing prescribed pharmacological mood stabilizer) for a period of 8 weeks. Measures of cognition, psychopathology and laboratory indices will be utilized for evaluating primary and secondary outcomes, along with safety assessments.

METHODS:

Up to Seventy-six subjects with DSM IV bipolar I disorder will be recruited from Western Psychiatric Institute and Clinic. Using a 1:1 randomization, subjects who sign an informed consent document will be randomized to receive Sensoril® or placebo.

It is expected that 16 of the 76 subjects may not meet inclusion/exclusion criteria, leaving 60 consenting adults (18 to 65 years) with DSM IV-TR Bipolar Disorder who will be assessed for euthymia (Young Mania Rating Scale Score of less than or equal to 10, Montgomery Asberg Depression Rating Scale Score of less than or equal to 10) over the period of 4 weeks while receiving stable doses of their current mood stabilizer. They will also be assessed for cognitive dysfunction (attention/executive function, immediate and declarative memory, psychomotor performance) using Cogtest - a proprietary neuropsychological battery of tests. These subjects will be characterized for normal pre-morbid IQ, no ECT treatment in past 6 months, no alcohol or substance dependence in past 6 months, mini-mental state score of 23 or more.

Sensoril® (or placebo) will be administered using random assignment at a dose of 250mg/day, increasing to a dose of 500mg/day by the second week. The dose of 500mg (or 250mg if tolerability is an issue) will be continued fora total of 8 weeks. Sensoril® is not known to have interactions with psychotropic drugs, but mood-stabilizer levels will be monitored at the beginning and end of the study. The principal investigator has worked with a New Jersey based company (Natreon, Inc.) to obtain an IND from the FDA for Sensoril® treatment of cognitive dysfunction in persons with Bipolar disorder (IND #102616).

Standard psychopathology rating scales will be administered to evaluate impact if any on residual symptoms of bipolar disorder. Laboratory indices (glucose/lipids) will be evaluated at baseline and end of study. Safety will be assessed through a comprehensive health assessment, including medical history, and evaluation of laboratory measures. Any adverse effects will be assessed by asking questions at each visit, and if necessary, follow up via telephone contact or bringing subjects in for assessments outside the scheduled visits.

SIGNIFICANCE:

Cognitive dysfunction can seriously hinder improved functional outcomes in persons with bipolar disorder. If this short term intervention with Sensoril® shows promise, more definitive studies using adequate powered sample sizes, and of longer duration can be conducted. If improvements in cognitive problems are linked to improved functional outcomes using such supplemental treatments, an important therapeutic milestone in bipolar disorder will have been achieved.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Digit-Span Score at 8 Weeks
Time Frame: 8 week treatment

Cognition was assessed using tests developed by The Cognition Group-(TCG); London, UK; and Delaware, USA. Testing procedures and consistency was assured by the same staff-patient dyad, and a TCG staff person had previously trained the research staff (Chengappa et al, 2012). A comprehensive cognitive battery was assessed. Details of these cognitive tests are available at http://www.cogtest.com, and are also described in other studies (Harvey et al, 2007, Lindenmayer et al, 2011, Chengappa et al, 2012). However, the results for Digit span which assesses short term or working memory are presented.

The raw scores for "digit span" ranges from a minimum of 2 to a maximum of 8. The Digit Span test measures working memory and the longer the span the better the cognition therefore the higher score is the better outcome.

Time Frame: Baseline and 8 weeks treatment
Manic symptoms were measured using the Young Mania Rating Scale (YMRS). Minimum score = 0, Maximum score = 60. Higher scores on YMRS indicate worse functioning.

Time Frame: Baseline and 8 week treatment
Symptoms of anxiety were measured using the Hamilton Anxiety Rating Scale (HARS). Minimum score = 0, Maximum score = 60. Higher scores on HARS indicate worse functioning
