Anti-Tau Therapies

Maryam Beigi, MD, Clinical Trial Physician; Associate Director of Kagan Clinical Trials ProgramBy: Maryam Beigi, MD

Alzheimer’s Disease is leading cause of dementia worldwide, and its prevalence is expected to double in the next 20 years. Clinical presentations include loss of memory, language or visual processing abilities, as well as neuropsychiatric symptoms such as apathy, depression, anxiety, agitation, and psychosis.

At autopsy, the brains of patients who lived with Alzheimer’s disease contain amyloid-beta plaques outside of cells and tau neurofibrillary tangles (NFT) inside of cells, along with extensive loss of neuronal synapses.

Scientists have postulated that these two proteins (amyloid-beta and tau), either alone or in combination cause disease initiation and progression. In our last newsletter I described the formation of amyloid-beta from the amyloid precursor protein (APP). The process of amyloid beta deposition in the brain starts 15-20 years before a person becomes symptomatic. Once symptoms of Alzheimer’s begin, the tau protein begins to aggregate at an accelerated pace.

Tau is a protein that binds to the highways within neurons for transportation of molecules. These highways can extend over a thousand times the size of the cell body. Tau supports the skeleton that holds these highways together inside neurons. Excess chemical modifications of tau (i.e. phosphorylation) are thought to cause the breakdown and collapse of the cellular skeleton, impairment of transportation of molecules, and ultimately loss of synapses and neurons and progression clinically to dementia (Fig. 1).

Recently, the focus of treatment discovery has shifted to tau, and many therapeutic interventions are currently undergoing research and development. Some of these therapies include tau vaccines, monoclonal antibodies against tau, and small pieces of DNA that can lower tau expression. Most of these therapeutics are in phase 2 trials and have shown to be safe, pending their efficacy in preventing or slowing progression of cognitive decline.

At UCLA we are starting a new trial with a monoclonal anti-tau antibody called the Autonomy study, which is sponsored by Janssen Research & Development, LLC. This is a double-blind, placebo-controlled phase 2 study for two years that includes monthly infusions. Participants should be in prodromal (Mild Cognitive Impairment) or early stages of Alzheimer’s disease.

Alzheimer’s Association Facts and Figures 2022: Special Report on Mild Cognitive Impairment

Monica Moore, Community Health Program Manager By: Monica Moore, MSG

Every year the Alzheimer’s Association releases an annual report on the state of Alzheimer’s disease and other related dementias. The report discusses prevalence, mortality and morbidity, as well as caregiving, the professional workforce, health care and long-term care relating to Alzheimer’s. The purpose of this report is to raise awareness of Alzheimer’s disease and the societal impact of dementia. The 2022 report was released in March and included a special report on Mild Cognitive Impairment (MCI).

Alzheimer's Association, Facts and Figures 2022, More than 6 million Americans are living with Alzheimer's

The number of people in America with Alzheimer’s disease is climbing and is currently at 6.5 million. This number is projected to increase as the US population over the age of 65 continues to grow, mostly due to the aging of the baby boom population. Age is the greatest risk factor for developing dementia, and the report states that 5.0% of people age 65 to 74, 13.1% of people age 75 to 84, and 33.2% of people age 85 and older have dementia due to Alzheimer’s disease. While the development of Alzheimer’s disease is typically associated with those over the age of 65, it is estimated that about 200,000 Americans under the age of 65 have what is known as younger-onset dementia. These numbers show the societal health crisis that is looming due to Alzheimer’s disease.

Mild Cognitive Impairment

The progression into Alzheimer’s disease is gradual. The changes in the brain that cause dementia-type symptoms often begin 20-30 years before diagnosis and occur while people are working, raising families, and going about their day. Yet, as the pathological changes occur in the brain, individuals may begin to experience problems with their thinking, remembering, reasoning, etc. This stage of cognitive loss is called Mild Cognitive Impairment (MCI). The cognitive changes are noticeable to the person with MCI as well as close relations, but may not be noticeable by others. These changes may be small and may not necessarily affect one’s ability to carry out daily activities and can sometimes be thought of as a normal part of aging. Yet, MCI is not normal and can be caused by a number of factors, one of them being Alzheimer’s disease. The varying causes of MCI, lack of accessible biomarker testing, and an underreporting of symptoms of MCI, makes diagnosis of MCI challenging.

MCI is more common than most people believe, as it is estimated that 1 in 7 Americans over the age of 60 can be classified as having MCI, but not all of them will develop Alzheimer’s disease. The report states that an estimated 10-15% of people with MCI will go on to develop dementia each year, most of which will be dementia of the Alzheimer’s type, yet some patients never experience further cognitive decline and others revert to normal cognition. As with dementia, one’s greatest risk factor for MCI is age, yet medication interactions, depression, sleep apnea, and a number of other conditions and lifestyle habits can be also be factors. Advancements in biomarker research, physician access to biomarker tests, and physician training can provide further insight into who will not progress into dementia, who will, and how interventions can prevent progression.

While MCI may be a familiar term at the Easton Center, the report states that only 18% (less than 1 in 5) Americans are familiar with this term and understand its meaning. Awareness and understanding of MCI was low across all racial and ethnic groups surveyed for this report. More than half of the survey participants believed that the cognitive loss associated with MCI is a normal part of aging. This lack of awareness prevents early evaluation and early intervention. Adding to the struggles for proper diagnosis, the report states that one third of primary care physicians (PCPs) were not comfortable diagnosing MCI and even more so for MCI due Alzheimer’s disease (50%). The PCPs believe that it is important to assess for MCI and to diagnose it but did not feel comfortable because of the lack of specialists and because limited treatment options exist.

Currently an FDA approved medication for MCI does not exist, but lifestyle modifications and medication interventions could reduce the chance of MCI developing into dementia. Accurate diagnosis of MCI due to Alzheimer’s disease can provide patients with the opportunity to participate in clinical trials aimed at intervention which could lead to an FDA approved treatment.

In order to properly care for those with MCI due to Alzheimer’s disease we need a stronger medical workforce properly trained in Alzheimer’s and dementia diagnosis and care. The 2022 Facts and Figures Report had an interesting section, on just this, entitled: Workforce.

Alzheimer's Association, Facts and Figures 2022, 1 in 3 seniors dies with Alzheimer's dementia

As mentioned previously, the rates of Alzheimer’s disease are increasing and therefore an unprecedented demand will be placed upon our medical system to provide care for this population. Yet, neurologists, geriatricians, psychiatrists, nurses, and other medical professionals trained in dementia care are in short supply. According to the 2022 report, the United States will have to nearly triple the number of specialists who were practicing in 2021 to effectively care for the approximately 10% of those 65 and older who are projected to have Alzheimer's dementia in 2050. This shortage is a direct barrier to early diagnosis, care, treatment and support services.

The UCLA Easton Center is setting up a program to train primary care physicians to recognize early stages of dementia through a dementia screening toolkit, available in Spanish and English. We will also work together with the Alzheimer’s Association through programs such as Project ECHO (Extension for Community Healthcare Outcomes) to help alleviate the stress on medical specialists.

The report also discusses the important and often neglected role of the caregiver, the effect that health care coverage has on patients and their families, and the role COVID-19 played on dementia care and mortality.
