Biomarkers for Alzheimer's disease can be trusted in clinical trials

15.11.2007
The best-established biomarkers for Alzheimer's disease have a low natural variation over two years. The results speak for the inclusion of these biomarkers in clinical trials of novel drugs against Alzheimer's disease.

The results are presented by researchers at the Sahlgrenska Academy at Göteborg University, Sweden, in the November 2007 issue of the Journal of Alzheimer's Disease.

"We show that the best-established diagnostic biomarkers for Alzheimer's disease stay at basically the same level during two years in patients with early Alzheimer's disease. This means that the biomarkers could be useful for detecting even minor biochemical changes induced by treatment in the clinical trials of novel drugs against Alzheimer's," says Henrik Zetterberg, Associate Professor at the Sahlgrenska Academy.

Dr Zetterberg and colleagues analyzed cerebrospinal fluid from more than 80 patients with mild cognitive impairment. Some of these patients developed full-blown Alzheimer's disease. The measured levels of the tau and amyloid-B proteins were compared in samples drawn from the same patients two years apart.

"If a novel drug candidate actually stops or slows down the neurodegenerative disease process in Alzheimer's disease, we should expect a normalized tau concentration in cerebrospinal fluid in patients on active treatment. Such a change should be readily detectable also in a small and inexpensive pilot study, given the low intra-individual variation in biomarker levels over time that was detected in our study," Dr Zetterberg says.

Alzheimer's disease is an age-related brain-damaging disorder that results in progressive cognitive impairment and death. Three decades of progress have resulted in a profound understanding of the molecular mechanisms underlying the disease. In the past 10 years, this knowledge has translated into a range of targets for therapy, the most promising of which is amyloid-B.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
