WHITEHOUSE STATION, N.J. & AUSTIN, Texas -- March 13, 2013

Merck (NYSE: MRK), known as MSD outside the United States and Canada, and
Luminex Corporation (NASDAQ:LMNX) have signed a collaboration and license
agreement to develop a companion diagnostic device that will be evaluated to
help screen patients for recruitment into Merck's clinical development program
for MK-8931, a novel oral beta amyloid precursor protein site cleaving enzyme
(BACE) inhibitor and Merck's lead investigational candidate for Alzheimer's
disease (AD). Financial terms were not disclosed.

“Evaluation of biomarkers that may provide an indicator of disease onset and
enable earlier diagnosis is an important goal toward facilitating early
intervention and potentially improving the treatment of Alzheimer’s disease,”
said Darryle D. Schoepp, Ph.D., senior vice president, head of Neuroscience
and Ophthalmology at Merck Research Laboratories. “We look forward to working
with Luminex to advance our ongoing clinical development program for MK-8931.”

Luminex will be responsible for development, regulatory submission and
commercialization of the candidate companion diagnostic device, which will
employ Luminex’s xMAP® Technology to measure concentrations of two candidate
biomarkers (Aβ42 and t-tau) in cerebrospinal fluid (CSF) samples from patients
with mild cognitive impairment (MCI). The candidate device will be evaluated
as a means to identify subjects with MCI who have a higher risk of developing
AD to support patient selection for Merck’s therapeutic BACE inhibitor
clinical program.

“This collaboration has the potential to deliver a novel companion diagnostic
to identify patients at increased risk of developing Alzheimer’s disease,”
added Patrick J. Balthrop, president and CEO of Luminex. “We are pleased to
leverage our technologies and development capabilities and look forward to
expanding our activity into the companion diagnostic segment of personalized

The accumulation of beta amyloid in the brain is a key pathological
characteristic related to AD. Recent clinical evidence supports the hypothesis
that the measurement of the investigational biomarkers Aβ42 and t-tau in CSF
may be useful in identifying patients at greater risk of developing AD.
Currently, AD is diagnosed by clinical examination (i.e., medical history;
physical, neurological, psychiatric and neuropsychological exams; and Magnetic
Resonance Imaging [MRI] or Computed Tomography [CT] scan). An AD diagnosis can
only be confirmed by histopathological identification of core features,
including beta amyloid deposits and plaques, in post-mortem brain samples.

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.^1,2 About 5.4 million people in
the United States are currently living with AD.^3 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

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. Information is also available at

In December 2012, Merck and GE Healthcare announced a clinical study
collaboration, license and supply agreement for use of [^18F]Flutemetamol, an
investigational positron emission tomography (PET) imaging agent, to support
development of MK-8931.
