Dexanabinol is the Company’s first neuroprotective agent. Dexanabinol does not bind to either of the known cannabinoid receptors. Its pharmacological activity is related to its ability to inhibit NMDA receptors and to block COX-2, cytokines and chemokine activation thereby acting as an anti-inflammatory and neuroprotective agent. Dexanabinol completed a Phase IIa clinical trial as an agent to prevent cognitive impairment following cardiac surgery. The potential of dexanabinol to treat other neuroinflammatory indications is under investigation.
Contrasting Dexanabinol With CBD Oil
CBD oil is great for many different things and the receptors are abundant in the brain.
There is no THC in most products that are advertised as CBD juices.
In November 2004, the Company announced the results of the double-blind, placebo controlled Phase IIa trial of dexanabinol as a preventive agent against cognitive impairment (CI) following coronary artery bypass graft (CABG) surgery. In this study, 202 patients aged 60 years or older with no clinical evidence of neurological or psychiatric symptoms and with no evidence of existing dementia undergoing elective CABG surgery were enrolled at six medical centers in Israel. Patients were given a single dose of either 150 mg dexanabinol or placebo just before surgery. Primary and secondary efficacy parameters were assessed for each patient at six weeks and three months post-surgery and compared to baseline pre-surgery scores. The primary endpoint was the effect of dexanabinol compared to placebo on reduction of post-CABG cognitive impairment as measured by five computerized tests plus the Stroop test and analyzed by multiple analysis of variance (MANOVA).
This is different from cannabidiol(CBD) in many ways.
First of all, we need a lot of terpenes in order to form a complete CBD profile in the human organism- average CBD oils just won’t cut it.
The trial did not achieve its primary statistical endpoint of detecting a statistical difference in the five composite cognitive test domains plus the Stroop test analyzed simultaneously by MANOVA (p=0.37). The power of the MANOVA, however, was substantially reduced by incomplete test data for 39 patients at three months. In a univariate output of the primary analysis, a trend toward significance was found in the Stroop test results. Further analysis using all available data revealed a trend toward significance at six weeks and at three months, the Stroop test achieved a statistically and clinically relevant difference when compared to placebo (p=0.01). This test showed that dexanabinol preserved higher integrative decision -making function when compared to placebo at three months post-surgery. The Stroop test is a test of selective attention and interference susceptibility. These skills have implications for the performance of everyday tasks that involve focused attention, cognitive impulse control, and decision-making. Improvements in the Stroop test by the dexanabinol-treated patients over the placebo-treated patients may reflect a preservation of the brain’s higher cognitive functions and learning mechanisms that can be vulnerable to effects from surgery. The data showed dexanabinol was safe and well tolerated in this study.
