Effect of Oral Intake of Bacopa Monneiri on Vascular Oxidative Stress — Bacoxy_I  

Cardiovascular Diseases Clinical Trial

Official title: Interventional, Open-label Study of the Effect of an Aquaporin-1 Inhibitor, the Bacopaside II Contained in Bacopa-400® , on Oxidative Stress in Healthy Volunteers: BacOxy_I Study

Status Completed

Clinical Trial Summary

Bacoxy_I study aims to evaluate the efficacy of a standardized Bacopa monnieri extract, Bacopa-400®, on vascular oxidative stress.

Clinical Trial Description

The Bacopa-400® is a standardized extract of a plant called Bacopa Monnieri, which mainly grows in India and neighboring countries. The virtues of this plant, also called Brahmi, have been used in Ayurvedic medicine for millennia in the treatment of chronic neurological diseases accompanied by cognitive impairment and memory disorders, as well as for stress management. Several companies have subsequently improved the preparation of standardized extracts of Bacopa Monnieri. Bacopa-400® from the Belgian firm Deba Pharma™ was selected because it adheres to good manufacturing practices (GMP). Currently, there are over 289 studies listed regarding the positive role of Bacopa monnieri in cognitive functions in both young and elderly subjects. Furthermore, no major side effects have been reported following the use of this plant extract in acute or chronic administration in hundreds of people of all ages.

Bacopa monnieri plant contains several bacosides, including the Bacopaside II a specific inhibitor of the water channel Aquaporin 1 (AQP1). AQP1 is part of the aquaporin family responsible for bidirectional transmembrane water transport. It is the most abundant aquaporin in mammalian cardiovascular tissue, present in myocardial cells, endothelial cells, and red blood cells. AQP1, more than a water channel, is also a peroxiporin able to facilitate the passage of hydrogen peroxide (H2O2), involved in oxidative stress.

In previous work, the Pharmacology and Therapeutics (FATH) department from UCLouvain (Brussels) discovered the protective effect of Bacopaside II on cardiovascular oxidative stress. Through a series of experiments, it was demonstrated that Bacopaside II dose dependently attenuates the passage of H2O2 into cardiac myocytes, thus preventing hypertrophy induced by neurohormones. Additionally, in murine models, oral administration of Bacopa monnieri extract attenuated cardiac hypertrophy triggered by hypertrophic stimuli. This cardiac protection occurs through inhibition of AQP1.

Based on this premises, a clinical investigation was undertaken to explore the potential of Bacopa-400® in attenuating vascular oxidative stress among healthy volunteers. This interventional, open-label and monocentric comprised two groups. Group A received a daily dose of 400 mg and Group B a daily dose of 800 mg over a 6-week period, followed by a 4-week observation period after the cessation of treatment.

The primary objective of this study was to assess the impact of Bacopa-400® on oxidative stress in healthy individuals and determine the optimal dosage for maximal efficacy. Furthermore, the study analyzed the incidence, severity, and frequency of adverse events, including suspected unexpected serious adverse events (SUSAR). ;
