Trial Design

2 Treatment Groups


This trial requires 200 total participants across 2 different treatment groups

This trial involves 2 different treatments. 18-F-Flortaucipir is the primary treatment being studied. Participants will all receive the same treatment. There is no placebo group. The treatments being tested are in Phase 4 and have been shown to be safe and effective in humans.

18F-Flortaucipir and 11C-Pittsburgh compound-B radioligands will be used for experimental PET imaging of beta-amyloid and neurofibrillary tau pathology
ControlNo treatment in the control group

What are common treatments for alzheimer disease?

Add answer

This meta-analysis suggests that there is no difference in efficacy for these five drug classes in Alzheimer disease or other dementias versus placebo. In addition, some of these treatments may be harmful. The benefit of most agents in this group does not appear to outweigh the risk of serious cardiovascular events. Further research is needed to assess cardiovascular risks and to consider alternative, alternative or combination treatments with known potential for greater benefits.

What causes alzheimer disease?

Add answer

There are several contributing factors to AD, and the exact causes remain a mystery. It is often simplified to a chemical imbalance in the brain, but the cause may also be due to underlying degenerative brain disorders, hormonal malfunctions, or infection. Understanding the causes behind AD can assist in research to find a cure for the disease.\n

How many people get alzheimer disease a year in the United States?

Add answer

Almost 1.1 million people in the US have Alzheimer's disease with an annual incidence of about 2 cases per 100,000 population. In addition, up to 8,000 people may be living with the disease at any one time. theme:

What are the signs of alzheimer disease?

Add answer

Signs of Alzheimer's include behavioural changes such as loss of personal and social interests, loss of motivation, and behavioural changes such as disorientation and deficits in memory. As for behavioural changes, apathy is also a symptom of Alzheimer's disease. Many doctors are unfamiliar with Alzheimer's, and do not recognise behavioural changes as a symptom of Alzheimer's.

Unverified Answer

Can alzheimer disease be cured?

Add answer

There is no cure for Alzheimer's disease. Treatment options can be effective for improving life expectancy and may reduce dementia symptom burden in some patients. Some treatments for dementia may improve Alzheimer's disease and reduce the risk of death.

What is alzheimer disease?

Add answer

Alzheimer's disease is a complex disorder leading to many psychiatric manifestations, in particular cognitive impairment, psychotic symptoms and behavioural disorders. The core characteristic of the disease is the loss of cholinergic neurons. The pathology is multifactorial and likely to have genetic and environmental components. The disease is progressive and often insidious, typically with a marked loss of cognitive function in people over 80 years.

Has 18-f-flortaucipir proven to be more effective than a placebo?

Add answer

Although [18F]T807 was superior to a placebo group at 3 months after single injection when it was used for imaging of brain regions affected in AD, [18F]T807 was not superior at 2 years with respect to delaying dementia onset and dementia severity compared with a placebo group.

Unverified Answer

What is the average age someone gets alzheimer disease?

Add answer

Researchers from the University of Edinburgh are working to provide a more precise assessment of the average age someone gets Alzheimer disease. Their study of family members suggests that many people who develop Alzheimer's disease have a family member who has had the condition longer and at a younger age. Current approaches to determining age at onset have relied on retrospective interviews and questionnaires, which lack precision. A detailed, comprehensive investigation of families with an affected member might shed new light on the ways in which mutations in the gene APOE can affect the disease.

Does 18-f-flortaucipir improve quality of life for those with alzheimer disease?

Add answer

18F-flortaucipir PET may have applications in AD. However, at least in studies with the sample size that were used (n=22), there was no significant relationship between the change in a specific cognitive domain (e.g., memory, executive function, etc.) and changes on the total cognitive and QoL domains. Given the relationship between cognition and QoL, further studies at large with a larger sample are warranted to tease out associations between the two variables.

Unverified Answer

What does 18-f-flortaucipir usually treat?

Add answer

18F-florbetapir PET scans can help treat patients after (18)F-florbetapir administration to determine if they have Alzheimer disease or if they have early changes consistent with Alzheimer's disease.

What is the latest research for alzheimer disease?

Add answer

Recent research indicates that the most promising discoveries in Alzheimer disease relate to biomarkers and imaging. To the best of his knowledge, he is not seeing any medication to treat AD. There are great strides to making dementia drug therapies more effective as well as less costly. Research is also showing that a medication that's used for anemia has been shown to be an excellent candidate for treatment of Alzheimer's disease. It has been demonstrated to reduce amyloid in the brain and decrease a peptide that destroys the synapses that normally help to keep memory functions in place. Studies show that the amyloid beta peptides can become more abundant in the brains of older individuals than the levels found in younger individuals.

Unverified Answer

Have there been other clinical trials involving 18-f-flortaucipir?

Add answer

Since [18F]f-fluorodoxyltricycline [18F]FDG-PET was applied in only 2 clinical trials, it is possible that [18F]f-fluorodoxyltricycline would have a potential use in the diagnosis of various neurological disorders, especially neurodegenerative disorders. Future directions of research on [18F]f-floridoxypyline and [18F]fluorodeoxyglucose are expected.
