Has The Controversy Around Falsified Alzheimer's Research Impacted The Path To Finding The Cure?

demonstrated that Alzheimer?s disease is associated with the production and buildup of amyloid deposits in the brain.

Despite treating what researchers believed to be a root cause of Alzheimer?s, aducanumab did not demonstrate the ability to impact clinical symptoms or outcomes such as worsening of cognitive abilities or dementia.

What Was The Problem With The Alzheimer?s Study?

Earlier this year, in an article published in Science, Dr. Matthew Schragg suggested that research in one of the primary studies on how amyloid deposits are associated with Alzheimer?s disease used falsified evidence.

The study in question was published in 2006 and has been cited in over 2,200 scientific papers since then. Its title, ?A specific amyloid-beta protein assembly in the brain impairs memory,? left little to the imagination. For the next 1? decades, this article would be one of the foundational resources for the amyloid hypothesis and Alzheimer?s research.

Unfortunately, Schragg?s discovery of potential image manipulation in the 2006 study suggests that Sylvain Lesn? and the rest of the researchers involved in the study may have altered images to make them support their hypothesis.

In response to Schragg?s observation, science integrity consultant Dr. Elisabeth Bik said that the 2006 study in question led to a significant amount of wasted research money and effort and has generated a lot of false hope for patients. Although the final determination on the value of targeting amyloid is still up for some debate, there is no doubt that the data led to an over emphasis on research on the amyloid hypothesis to the detriment of other approaches.

While there are currently drugs like Donepezil, produced by Pfizer Inc. (NYSE: PFE) and Eisai Co. Ltd. (OTCMKTS: ESALY), that helps some of the symptoms associated with dementia, there is still no cure for dementia to date.

Where Does Alzheimer?s Research Go From Here?

Biotech companies are researching alternative Alzheimer?s treatments that do not revolve around the research on amyloid deposits as the root of Alzheimer?s. These companies are opening up new and promising targets (pathways) to treating the disease that hadn?t been pursued in the past given the potentially flawed belief that amyloid deposits were the cause of the disease.

One such company is NervGen Pharma Corp. (TSX-V: NGEN) (OTCQX: NGENF). NervGen?s technology is focused on mechanisms to repair damage to the brain and spinal cord. When there is damage to the nervous system, whether by injury or disease, there is a build-up of a class of chemicals called chondroitin sulfate proteoglycans (CSPGs). CSPGs play a key role in inhibiting the brain's own natural repair mechanisms. NervGen has developed a molecule, called NVG-291, that interferes with the inhibitory effects of the CSPGs, and that promotes the brain?s repair mechanisms, with some very dramatic results seen in preclinical disease models such as spinal cord injury and stroke.

Of particular relevance to Alzheimer?s is research that has found an association between CSPGs and progression of the disease. The study looked at the levels of CSPGs in the brain in healthy aged subjects, patients with mild cognitive impairment, and patients with Alzheimer?s disease and found that the highest levels of CSPGs in the brain were found in Alzheimer?s patients, and the lowest levels were found in the healthy aged subjects.

Some preclinical studies have found that breaking down CSPG deposits may help improve Alzheimer?s symptoms. Other studies have suggested that by removing the cellular receptor that CSPGs bind to, a protein known as tyrosine phosphatase sigma, may help improve cognitive function for Alzheimer?s patients.

In response to these studies, NervGen says it developed NVG-291 to relieve the inhibitory effects of CSPGs, improving the function of neurons and strengthening the connection between neurons.

While falsified data in major Alzheimer?s research is a legitimate cause for confusion and anger, it should not impact the tenacity with which researchers are looking for the cure. As NervGen CEO Paul Brennan put it, ?The findings of image manipulation has no relationship at all with the science supporting the use of NVG-291 in Alzheimer?s disease, and in fact, it underlines the importance of taking a diversified approach to trying to solve it.?
