About Alzheimer's Disease and Amyloid Hypothesis
Alzheimer’s disease (AD) is a devastating, irreversible and ultimately fatal disease that progressively destroys neurons in the brain, leading to a deterioration of cognitive function. The symptoms include loss of memory that progresses into behavioral changes, alterations in thinking and reasoning skills that interfere with daily activities, and dementia. AD is the most common cause of dementia, accounting for approximately 50-75 percent of the estimated 35 million dementia cases globally.
About 5.4 million people in the United States are currently living with AD.
There are currently no disease-modifying treatments available for AD, and treatment options are limited to providing symptomatic improvements with only modest and short-term effects.
While the exact cause of AD remains unknown, the current prevailing hypothesis asserts that AD occurs due to the accumulation of beta amyloid proteins in the brain. Beta amyloid precursor protein site cleaving enzyme (BACE) is believed to be a key enzyme in the production of beta amyloid peptide, which contributes to the formation of plaques in the brain. Evidence suggests that inhibiting BACE decreases the production of beta amyloid and may therefore reduce amyloid plaque formation and modify disease progression.
About Merck’s BACE Inhibitor Development Program and MK-8931
Merck is advancing several innovative programs in Alzheimer's disease, including candidates designed to modify disease progression as well as improve symptom control. Merck's lead candidate in disease modification is MK-8931, an investigational oral BACE inhibitor.
Results of Phase I clinical studies demonstrated that MK-8931 can reduce levels of beta amyloid in cerebral spinal fluid (CSF) by greater than 90 percent in healthy volunteers and people with AD without dose-limiting side effects. Based on these results, Merck is conducting a global, multi-center Phase II/III clinical trial, EPOCH, to evaluate the safety and efficacy of MK-8931 versus placebo in patients with mild-to-moderate AD and has plans to initiate a trial in prodromal subjects.

In December 2012, Merck and GE Healthcare announced a clinical study collaboration, license and supply agreement for use of [
F]Flutemetamol, an investigational positron emission tomography (PET) imaging agent, to support development of MK-8931.
