About this study

Official title: Chronic Effect of Brahmi on Cognition Performance and Anxiety in Healthy Indian Adults and Exploration of Pharmacokinetic Properties of Brahmi Components in Healthy Adult Males.

The Indian Ayurvedic herb Brahmi (Bacopa monniera) has been used to improve cognitive functions in Indian sub-continent for many years and previous intervention studies have shown positive effects of Brahmi on cognitive performance in adults. However, the studies are conducted on various fractions and extracts and there is high likelihood of variability of composition amongst the fractions/extracts tested in these studies. Furthermore, although the findings of the previous studies overlap to some extent, they are not consistent and there is a need to replicate these findings.

Further, even though Brahmi has been studied for its chemical composition and its therapeutic benefits as a whole, there are still severe gaps with respect to the complete composition of the Brahmi plant or its extracts. No published data exist on the Pharmacokinetics (PK) properties of Brahmi components. Hitherto, the evidence and the mechanistic details are still speculative and the biological activity is still phenomenological. Because of this severe knowledge gap, this study will try to repeat the findings on cognitive performance and at the same time also explore the plasma levels of its components in order to initiate the understanding of ADME aspects and its linkages to the biological effect.

Read the detailed description

The study is proposed to be a randomised, double blind, placebo-controlled study with parallel groups. The duration of the study will be 12 weeks.

For cognition and Anxiety part, each selected subject will be paying 4 visits to clinical site for the whole study. Screening/selection will be done on visit 1, baseline on visit 2 and post-intervention assessment on visit 3. Subjects will be asked to appear for an interview before the investigators once more within one month of completion of intervention to take care of issues, if any. This will be 4th and last visit.

Each subject will be assessed at baseline (Week 1, Day 1); while post intervention assessment will be carried out immediately on the completion of the 12 weeks. Considering the 84 days duration of the study, + 3 days for the intervention period will be acceptable. The exact intervention duration will be documented in days for each subject.

On each of the two measurement days (baseline and post intervention), the same test battery will be administered by the same examiner. The outcome measures of this battery include Verbal Learning and Memory, Information Processing, Attention and Interference and Anxiety. The test battery will be administered in English.

On each of the measurement day the subject will spend a maximum of 1½ hours at the clinical site. Subjects will be examined in the morning at approximately the same time during both measurement days to keep conditions constant across the subjects and for baseline and post intervention assessments.

Each subject participating in Pharmacokinetics (PK) part, will pay 6 visits. Visit 1 will be screening, Visit 2,3 and 4 for initial blood withdrawal and visit 5 will post intervention blood sampling. Subjects will be asked to appear for an interview before the investigators once more within one month of completion of intervention to take care of issues, if any, which will be visit 6.

Blood sampling will be done at 0,1,2,4,8,24,48 hours and one sample at the endo of 12 weeks intervention.

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 6 inclusion and 14 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 4 Jun 2015. 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 India. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?

Change in Delayed recall from Baseline at day 0 to post intervention at day 84 (time frame: "0" (baseline) day and "84" day (Post Intervention)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 4 Jun 2015.
