(10/27/16)- We at therubins received the following request that is looking for qualified volunteers for a clinical trial that is seeking to find some answers in connection with Alzheimer’s disease:
“What if we could slow the progression of Alzheimer’s
disease with better sleep?
Recent research suggests there may be a link between sleep, cognitive dysfunction, and Alzheimer’s disease. ReCOGNITION is a research study testing whether an investigational medication, which has sleep promoting effects, can help to slow cognitive deterioration, or improve cognitive function.
We need people to participate in this research study who:
Are between 60 to 85 years of age
Have been diagnosed with mild dementia due to Alzheimer’s disease
Do not have an alternative cause for dementia other than Alzheimer’s disease
Have a caregiver who stays under the same roof at least 3 nights a week and is willing to attend all study visits

Qualified participants will be seen by a doctor and receive all study-related exams, care and medications at no cost. Compensation may be available. This study is sponsored by Neurim Pharmaceuticals (1991) Ltd.”
(10/28/13)- Government officials announced a $33.2 million grant as part of its national Alzheimer’s plan that will help finance a clinical trial to test a treatment on people 60 to 75 years of age who have no symptoms of the disease, but do have two copies of a gene known to greatly increase the risk of getting the disease.
The project will be led by Dr. Eric M Reiman and
Dr. Pierre N. Tariot of the Banner Alzheimer’s
Institute in Phoenix, Az. The clinical trial will take place mostly in the
States on 650 patients who have two copies of the gene ApoE4.
Studies have shown that more than half the people with two ApoE4 genes will develop Alzheimer’s, compared with about one-fourth of people with one copy and 10 percent
(10/27/13)- A protein that is
increased by endurance exercise has been isolated and given to non-exercising
mice, in which it turned on genes that promote brain health and encourage the
growth of new nerves involved in learning and memory, report scientists from
the Dana-Farber Cancer Institute and Harvard Medical School.
The findings, reported in the journal Cell Metabolism, help explain the well-known capacity of endurance exercise to improve cognitive function, particularly in older people. If the protein can be made in a stable form and developed into a drug, it might lead to improved therapies for cognitive decline in older people and slow the toll of neurodegenerative diseases such Alzheimer's and Parkinson's, according to the investigators.
"What is exciting is that a natural substance can be given in the bloodstream that can mimic some of the effects of endurance exercise on the brain," said Bruce Spiegelman, PhD, of Dana-Farber and HMS. He is co-senior author of the publication with Michael E. Greenberg, PhD, chair of neurobiology at HMS.
The Spiegelman group previously reported that the protein, called FNDC5, is produced by muscular exertion and is released into the bloodstream as a variant called irisin. In the new research, endurance exercise -- mice voluntarily running on a wheel for 30 days -- increased the activity of a metabolic regulatory molecule, PGC-1α, in muscles, which spurred a rise in FNDC5 protein. The increase of FNDC5 in turn boosted the expression of a brain-health protein, BDNF (brain-derived neurotrophic protein) in the dentate gyrus of the hippocampus, a part of the brain involved in learning and memory.
It has been found that exercise stimulates BDNF in the hippocampus, one of only two areas of the adult brain that can generate new nerve cells. BDNF promotes development of new nerves and synapses -- connections between nerves that allow learning and memory to be stored -- and helps preserve the survival of brain cells.
How exercise raises BDNF activity in the brain wasn't known; the new findings linking exercise, PGC-1α, FNDC5 and BDNF provide a molecular pathway for the effect, although Spiegelman and his colleagues suggest there are probably others.
Having shown that FNDC5 is a molecular link between exercise and increased BDNF in the brain, the scientists asked whether artificially increasing FNDC5 in the absence of exercise would have the same effect. They used a harmless virus to deliver the protein to mice through the bloodstream, in hopes the FNDC5 could reach the brain and raise BDNF activity. Seven days later, they examined the mouse brains and observed a significant increase in BDNF in the hippocampus.
"Perhaps the most exciting result overall is that peripheral deliver of FNDC5 with adenoviral vectors is sufficient to induce central expression of Bdnf and other genes with potential neuroprotective functions or those involved in learning and memory," the authors said. Spiegelman cautioned that further research is needed to determine whether giving FNDC5 actually improves cognitive function in the animals. The scientists also aren't sure whether the protein that got into the brain is FNDC5 itself, or irisin, or perhaps another variant of the protein.
Spiegelman said that development of irisin as a drug will require creating a more stable form of the protein.
(4/12/13)- The conclusion of a study of the cost of dementia conducted by the Rand Corporation was that it was costing between $157 billion and $215 billion a year in medical care and other costs, such as lost wages for caregivers.
The results of the study were published in a recent edition of the New England Journal of Medicine. The researchers examined a group of more than 10,000 adults age 71 and older who were enrolled in a large national representative study called the Health and Retirement Study. It was estimated that 14.7% of those in the sample were afflicted with dementia.
The Alzheimer Association estimates that there are presently 5.4 million American who are suffering from this malady.
The direct medical cost of treating dementia is estimated at $109 billion in 2010, compared to $102 billion for those who suffer from heart disease and $72 billion for those with cancer.
(2/7/13)- According to the U.S. National Institutes of Health's ClinicalTrials.gov website, there are currently 139,372 clinical studies being conducted throughout 182 countries as of Jan. 28, 2013.
The number of registered clinical studies has increased by an average of 28% annually since the year 2000. According to Pharmaceutical Research Manufacturers of America, the pharmaceutical companies lobbying organization, $49 billion was spent last year on researching more than 2,900 compounds.
(5/21/12)- Can Alzheimer's Disease be prevented before it takes its dreaded toll? A $100 million trial, funded by a combination of the federal government, academic researchers, charitable foundations and the drug maker Genentech Inc., which is a subsidiary of Roche Holding AG are going to try and find out.
The drug that will be used for the test is an injectable one named crenezumab. The drug is currently being tested in two clinical trials in this country, Canada and western Europe with people with mild to moderate symptoms to see if it can reduce cognitive decline or amyloid accumulation, with Genentech sponsoring these studies.
The trial will be financed with $16 million form the National Institutes of Health, $15 million from private donors through the Banner Institute and about $65 million from Genentech.
It is hoped that crenezumab will help to break up the clustering of amyloid plaques in the brain. It has not been found to have any negative effects on the brain.
About 300 of the participants in the study will come from Medelin, Columbia because they come from an extended family with a specific genetic mutation, so that they begin to show signs of the disease at 45, and full dementia at 51.
The drug trial is part of the federal government's first national plan to address Alzheimer's Disease (The National Plan to Address Alzheimer's Disease), and it was unveiled by Kathleen Sebelius, the secretary for health and human services.
The trial will start in 2013, and the patients will be treated for up to 5 years.
The NIH also made a $7.9 million grant for a study testing the effectiveness of an insulin spray in treating patients in the early stages of the disease.
(9/14/10)- A recent email from one of our readers asked the question about the essential steps in a medical (clinical) evaluation. We consulted the Centers for Disease Control and Prevention Toolkit for Health Care Professionals and came up with the following:
A detailed patient history, including a review of
A thorough physical examination.
A mental status screening.
A minimum battery of laboratory screening tests including:
Alanine aminotranferase or aspartate transaminase serum level.
Albumin and rheumatoid factor.
Blood urea nitrogen.
Complete blood count with leukocyte differential.
Thyroid function tests.
Other test may be included if the treating physician is looking for specific factors in arriving at a differential diagnosis
(8/26/10)- Eli Lilly & Co. announced that it was halting development of its experimental Alzheimer's disease drug semagacestat, after studies showed it was worsening the patients' conditions, and was associated with an increased risk of skin cancer.
Lilly has another experimental AD drug candidate, solanezumab, in late stage development that is not affected by this decision,
Thus, although the news recently concerned being able to determine whether or not an individual is going to be afflicted with the disease through a spinal tap, the battle to find a cure for the disease continues to baffle the scientific community
Semagacestat is a gamma secretase inhibitor that was designed to work by blocking an enzyme in the brain that causes the formation of amyloid plaque. It was designed to deal with patients who had mild-to-moderate Alzheimer's
The interim analysis found that cognition and ability to complete daily activities in patients taking the drug worsened to a greater degree than those taking a placebo. The patients taking semagacestat also had a higher rate of skin cancer.
(7/25/10)-In a study conducted by researchers at the Massachusetts Institute of Technology, that was funded by an American Parkinson Disease Association fellowship and grants from the National Institutes of Health and the Paul E. Glenn Foundation, which backs research on the biology of aging, it was shown that by working on the gene, SIRT1, in the brains of mice, it was possible to reduce their erosion of memory and learning ability.
The gene.regulates the production of a class of proteins known as sirtuin 1. Mice with a model of Alzheimer's disease that were genetically engineered to produce more sirtuin 1 retained both memory and learning ability as they aged
Mice without the enhanced sirtuin capability, and those engineered to produce no sirtuin 1 at all, showed steep declines in learning ability and memory as they aged. SIRT1 has been described at the "longevity gene". Studies have shown that a highly calorie-restricted diet can turn on the gene and thereby increase longevity in everything from yeast to mice
The question remains however as to whether or not there is a connection between
SIRT1 and Alzheimer's disease
(6/13/10)- In attempting a new approach at getting to the bottom of Alzheimer's disease, 5 of the major drug companies have agreed to pool their data as to the results of their failed clinical trials. Data from 4,000 patients involved in 11 failed AD clinical trials are now publicly available for all to see.
The drug companies involved in this project are Johnson & Johnson, GlaxoSmithKline PLC, Astra-Zeneca PLC, Sanofi-Aventis and Abbott Laboratories.
The coalition intends to create a similar pooled database for Parkinson's disease and tuberculosis in the future.
FDA Deputy Commissioner Joshua Sharfstein said, "I think the FDA recognizes that one thing that can accelerate drug development is sharing information that is relevant to a disease."
(10/27/08)-A biomarker is a term for something present in the body which can indicate disease, such as a certain protein or molecule. The Nottingham team will be identifying biomarkers by looking at proteins in the blood of Alzheimer's patients compared to a control group of healthy older people.
The researchers at The University of Nottingham hit upon the idea of using biomarkers as a means of diagnosis and will be involved in collecting the samples in conjunction with collaborators in the UK and EU, while the samples will be tested using technology based at Nottingham Trent University.
Researchers from Nottingham's two universities are joining forces to develop a simple blood test to diagnose Alzheimer's disease. The Ł200,000 study, funded by the leading charity the Alzheimer's Research Trust, will aim to find out whether 'biomarkers' in blood could be used to identify someone with Alzheimer's.
(6/22/08) Would you bet on a drug that has a thirty percent chance of reaching the market? Apparently, many stock investors had this idea on Tuesday, June 17, when the stock of the pharmaceutical company, Wyeth, rose 4.83 percent on a potential product for treating Alzheimer’s disease. The drug is bapineuzumab, "one of 23 paths that Wyeth is exploring under its so-called war on Alzheimer’s" (NY Times June 18, C2). Phase 3 stage of this drug evaluation started in Dec. 2007. It is a multicentered, randomized, double-blind, placebo-controlled, parallel-group, efficacy and safety trial in patients with mild to moderate Alzheimer’s disease who are apolipoprotein E4 non-carriers. The study is expected to be completed in Dec. 2010

(5/21/07)- The Alzheimer’s disease Cooperative study (ADCS) has received $52 million over 6 years to test drugs for their effectiveness in slowing down the progression or treating the symptoms of AD. The ADCS is a consortium of centers that will be conducting clinical trials, with the University of California, San Diego (UCSD) coordinating the work done at 70 centers in the United States and Canada. Richard J. Hodes, Director of National Institute on Aging (NIA), is quoted as saying: "We have learned a great deal from basic and observational research about how Alzheimer’s and other neurodegenerative diseases develop. The consortium’s work will translate this knowledge in clinical trials of interventions that target the mechanisms underlying AD."
The ADCS was established in 1991 bringing together leading researchers to carry out clinical trials for promising new therapies for AD. Investigators in the consortium have done studies on vitamin E, selegiline, estrogen, NSAIDs and donepezil. There are also ongoing studies of statins, high dose folate/B6/B12 supplements, and valproate to determine whether these compounds can either slow decline or help delay symptoms that emerge in AD patients. They will now do trials with docosahexaenoic acid (DHA), an omega-3 fatty acid, intravenous immunoglobulin (IVIg), lithium and also study alternative ways for the very elderly to take part in research studies.
The principal investigator at UCSD is Leon Thal, MD, chair of the Department of Neuroscience. For more information about thesestudies check www.nia.nih.gov/Alzheimers/Researchinformation/ClinicalTrials

(8/04/06)- Insulin Sensitizer Rosiglitazone (Avandia) and APOE4 in Alzheimer’s Disease
According to the Clinical Trials.gov site (viewed Aug. 1, 2006), GlaxoSmithKline is set to launch a study of Rosiglitazone (Extended Release Tablets) as adjunctive therapy for subjects with mild to moderate Alzheimer’s disease (Clinical Trials. Gov Identifier NCT00348309). The study will be a randomized, double-blind, placebo control, parallel assignment efficacy study to investigate the efficacy of rosiglitazone (Rosiglitazone is sold under the brand name Avandia) as adjunctive therapy to donepezil on cognition and overall clinical response in APOE e4-stratified subjects with mild to moderate Alzheimer’s disease. They expect to enroll 1392 subjects at a number of sites throughout the USA.
In the publication CNS Drugs 2003,17(1):27-45, G. S. Watson and S. Craft (Geriatric Research, Education and Clinical Center, Veterans Affairs Puget Sound Health Care System, Seattle WA) reviewed evidence suggesting that insulin resistance plays a role in the pathophysiology and clinical symptoms of Alzheimer disease. Based on this evidence, these researchers proposed that the treatment of insulin resistance may reduce the risk or retard the development of Alzheimer’s disease. This has lead to investigators looking at the role of insulin sensitizers as a treatment. Insulin resistance refers to clinical condition in which the biologic response to insulin is diminished to below normal levels.
"University of Buffalo endocrinologists, led by Paresh Dandona, M.D., professor of medicine and head of the Division
of Endocrinology in the UB School of Medicine and Biomedical Sciences, have
been studying the anti-inflammatory properties of insulin and insulin
sensitizers and their potential use in treatment and prevention of
atherosclerosis, one of the leading causes of heart attacks.
Atherosclerosis, or hardening of the arteries, begins as an inflammation of the blood-vessel wall. Persons with diabetes are at increased risk of developing atherosclerosis and heart disease. Dandona’s lab has shown in research with a small group of obese non-diabetic volunteers that rosiglitazone decreased the levels of oxygen free radicals, which can begin the inflammation cascade by injuring blood-vessel linings. The drug also decreased the levels of several blood markers of inflammation." (Information accessed Aug. 2, 2006 at www.innovations-report.de/html/berichte/medizin_gesunheit/bericht-10622.htm)
Alzheimer’s disease patients treated with rosiglitazone maleate, an insulin sensitizer and mitochondrial stimulator appear to have improved cognition. (See: M.E. Risner et al, "Efficacy of rosiglitazone in a genetically defined population with mild to moderate Alzheimer’s disease, Pharmacogenomics J. (in press) 2006 and S. Ye et al., "Apolipoprotein (apo) E4 enhances amyloid ß peptide production in cultured neuronal cells: APOE structure as a potential therapeutic target." Proc Natl Acad Sci 2005; 102:18700-5.)
The scientific community is hard at work looking at the properties and function of APOE. They now know that APOE plays a basic role in the transport of lipids in the body as well as in the repair of neurons. Human APOE is 299 amino acids long and its gene is found on chromosome 19. The three variants of APOE are called alleles-ApoE2, ApoE3, ApoE4. The latter allele is considered a major risk factor for Alzheimer’s disease. Robert Mahley and Xadong Huang writing in The Scientist, 2006; 20(4):49-54 believe "that apoE4 works in concert with a variety of insults or so-called second hits to lead to neuropathology".
These three alleles differ only at two positions, 112 and 158. The differences result in different biophysical properties that likely contribute to the finding that ApoE4 imposes malfunctioning cell machinery leading to pathology. It appears to "enhance amyloid beta production, potentiate amyloid beta-induced lysomal leakage and apoptosis, and enhance neuron-specific proteolysis (the directed degradation (digestion) of proteins by cellular enzymes called proteases or by intramolecular digestion, ed. insert) resulting in translocation of neurotoxic apoE4 fragments into the cytosol (the internal fluid of the cell, and a portion of cell metabolism occurs here, ed. insert) where they are associated with cytoskeletal disruption and mitochondrial dysfunction". (The Scientist. ibid) The goal of those researchers looking at a drug therapy for Alzheimer’s disease is to convert the apoE4 to apoE3-like molecule. If this could be done, the apoE3 allele is not neuropathologically detrimental, thus reducing the risk of developing Alzheimer’s disease. The question remains whether rosiglitazone is a promise of a cure for one of our most debilitating ills. Meanwhile, research continues on many different fronts to deal with Alzheimer’s disease, that, as the elderly population increases, is looming as a large health crisis in the near future.

As the population ages, it has been predicted that more individuals will develop Alzheimer’s disease. Alzheimer's disease ranks as the eighth-leading cause of death in the U.S., and accounted for 44,507 deaths in 1999. It is estimated that Alzheimer’s disease costs society about $33 billion annually, with average lifetime cost per individual at about $174,000.
In 1999, the United States government will spend approximately $400 million for research, which works out to $1 for every $250 the disease now costs. This money mainly goes for clinical trials designed to find new and better medications to deal with the symptoms related to the disease, and hopefully to cure the disease.

Outreach and Promotion Specialist
Alzheimer's Disease Education and Referral Center
Dear Mr. Rubin -
Thanks so much for your inquiry about Alzheimer's disease clinical trials. I had a chance to look at your Web site which is terrific!
Since we talked, the Healthy Aging and Memory Study has completed recruitment and is no longer seeking volunteers.
The Homocysteine study is not yet underway - the study sites are in process of gaining approval from their Institutional Review Boards (IRBs). The name of the study is "VITAL" (VITamins to slow ALzheimer's) and it will seek to discover whether lowering homocysteine with
high-dose supplements of folate, B6, and B12 will slow cognitive decline in people with AD. Paul Aisen, MD, of Georgetown University is directing the study. Approximately 40 sites will enroll a total of 400 volunteers age 55 or older with mild to moderate AD for this 18-month trial.
You are signed up for our e-mail alert service and will receive an e-mail when any new trials are recruiting participants. You can also check back on our Web site at www.alzheimers.org.
Thanks again for your interest and for spreading the word! Please let me know if I can be of any further assistance.

ADAPT, PREPARE and PREADVISE mentioned in the chart below are sponsored by the National Institute on Aging. The National Center for Complimentary and Alternative Medicine is sponsoring the GEM study at the National Institute of Health.
ADAPT (AD anti-inflammatory Prevention Trial)
People 70+ who have not been diagnosed with AD but have a relative who had the disease
PREPARE ( Preventing Postmenopausal Memory Loss and AD with Replacement Estrogens)
1 877 DELAY-AD
PREADVISE (Prevention of AD by Vitamin E and Selenium)
Men 60 to 90 years of age
GEM ( Ginkgo Evaluation of Memory)
People 75+ with dementia
Closed to new participants
The Danish pharmaceutical company Lundbeck LUN.CP said its drug Memantine for treatment of Alzheimer's disease was recommended for approval by a European Union committee. Forest Labs has the marketing rights in the U.S. Memantine is the first drug to do clinical trials in patients with severe Alzheimer's although it is not likely to be more effective than the current Alzheimer drugs on the market. The drug is not expected to be on the U.S. market for approximately two years.
Elan and Wyeth-Ayerst Labs (a division of American Home Products) announced
that it has suspended patient dosing in it Phase 2A study of AN-1792, which we
discuss in Study Number 2 below. The study has been suspended and the drug will
not be going forward in development because four patients were reported to have
signs of inflammation of the Central Nervous System (CNS).
The December 21, 2001 issue of Nature indicated that researchers using a transgenic mouse model of Alzheimer's disease were able to demonstrate that accumulation of amyloid-beta protein deposits correlated with cognitive decline. They showed that a vaccine could reduce the amyloid-beta protein deposits and reduce impairments in learning and memory. This sounds like good news, but for many in the scientific community, there still is a question of whether it is the amyloid-beta plaques that cause dementia. Some researchers are focusing in on two separate Alzheimer disease genes located on chromosome 10 that play a part in regulating amyloid-beta levels.
A number of our readers have asked us about volunteering for studies being
done with possible new AD medications. We recently received the following
e-mails outlining two current studies that are recruiting subjects. There are
phone numbers listed where you could check it out for yourself, since we make
no recommendations in connection with the studies.

Study Number 2-This study has been suspended and will not be going forward.
PROTOCOL NUMBER :IA0030
BRIEF TITLE: Randomized Safety, Tolerability and Pilot Efficacy of AN-1792 in Alzheimer's Disease
DESCRIPTION FOR THE PUBLIC
The study enrolled approximately 375 patients with mild to moderate Alzheimer's disease at investigational sites in the United States and Europe. Patients received either AN-1792 or placebo, and were evaluated using standard clinical assessments of cognition and memory as well as experimental surrogate markers of Alzheimer's disease pathology. The goal of the study was to evaluate the clinical impact of eliciting an immune response (formation of antibodies) to the A-beta peptide in patients with Alzheimer's disease. As we discussed above this study has been stopped because of problems that have developed in some of the patients who received the drug.
SPONSORING AGENCY: Elan Pharmaceuticals, Wyeth-Ayerst
CONTACT PERSON: Elan Pharmaceuticals 888-635-9987 (US), 800-898-3736 (International)
Data was presented at the World Congress of Neurology, based on a 12-month study of Reminyl (R) (galantamine hydrobromide) that the drug which has been approved for treatment of mild to moderate Alzheimer's disease, also may be effective in treating dementia in individuals with cerebrovascular disease. Reminyl is comarketed by Shire Pharamaceutical and Johnson & Johnson. Janssen Pharmaceutical Products announced that the FDA has approved a new oral solution formulation of its Alzheimer's disease therapy Reminyl. It may prove valuable to those patients who have difficulty swallowing pills.
The FDA has granted approval to Johnson & Johnson for its drug Reminyl to treat mild-to-moderate cases of Alzheimer's disease. According to a company spokesman the drug will be available to the public starting in May 2001. Its price will be about the same as 2 other medications now being used to treat Alzheimer's disease. The other 2 drugs are Aricept, sold by Pfizer, Inc., and Exelon sold by Novartis AG of Switzerland. Reminyl was shown to be effective in improving or helping to stabilize patients' ability to think and perform daily tasks of living. The test group used to evaluate the drug consisted of 2,650 subjects. Side effects reported in connection with taking the drug included nausea, vomiting, anorexia, diarrhea and weight loss. The Janssen Research Foundation, a subsidiary of Johnson & Johnson developed the drug, under a co-development and licensing agreement with Shire Pharmaceuticals Group PLC.
The May 10, 2000 issue of JAMA (an American Medical Association publication) column titled "The World in Medicine" discussed a "promising" new drug for Alzheimer’s disease treatment. The drug, Galantamine Hydrobromide, marketed as Reminyl, is for treatment of mild to moderate cases of Alzheimer’s disease. The European studies indicated that 24 mg/d is the dosage that is most effective, improving scores on the Alzheimer’s Disease Assessment Scale in memory, language, orientation and other aspects of cognition over a one year period.
Galantamine is classified as Acetylcholinesterase inhibitors. It also appears to act on nicotine receptors in the brain. Both the acetylcholine and nicotine receptors have been suggested as areas related to cognitive impairment.
It remains to be seen whether this drug is any better than those already on the market in the USA. It does not pretend to be a cure for Alzheimer’s disease, but may retard the cognitive decline.
Researchers are still trying to pin down the process of memory impairment in the brain. Neurotransmission in the brain is a complex phenomenon, involving different receptor sites. Different mechanisms of action may precipitate different profiles of AD and call for different forms of treatment. The hallmarks of Alzheimer’s disease involve extensive amyloid plaque formation, neuritic dystrophy, synaptic loss and gliosis. These pathological and biochemical changes are the target of drug treatment. It is not yet known what causes these pathologic changes, although genetics and age are risk factors and theories abound.
Media reports have been suggesting that a "vaccine" is on the way which is being developed by Elan Corporation. Please note that research is only in the first clinical trial phase of development to make people immune to beta-amyloid plaque formation. This month's issue of the journal Nature reports on a study performed by scientists at Massachusetts General Hospital in Boston and Elan Corp of Dublin. The brains of mice with genetically induced Alzheimer's disease were injected with an antibody known to attack beta-amyloid, a plaque that normally builds up and clogs the brains of people with Alzheimer's disease. A protein injection melted away the brain-clogging beta-amyloid plaque. The literature indicates that you can have beta-amyloid plaque formation and not have symptoms of AD and that plaque formation is a ubiquitous phenomenon in human beings. It will be many years before this vaccine becomes available to the public and then, only if it passes all phases of drug development and long-term clinical use. Some scientists believe that the beta-amyloid buildup is merely a symptom of Alzheimer's disease and that therapies aimed at clearing them up will not cure the underlying disease.
To keep our readers informed, we present a further list of drugs in clinical trails. These drugs are based on the theory that stimulating the cholinergic, muscurinic or nicotinic synapses could alter the progression of the disease. Most are aimed at palliative treatment. Presently, cholinesterase inhibitors are the only approved pharmaceutical treatment of AD. Cholinesterase inhibitors block acetylcholinesterase, preserving acetylcholine for a longer period of time, thus preserving brain cell communication. The most common adverse events of this class of drugs involve the gastrointestinal tract: nausea, vomiting and diarrhea. Physicians will lower the dose when these affects show up, until the individual becomes tolerant and then building the dose up again. The drugs listed below may have a wider range of adverse effects and are not available for treatment of AD in the USA.
