Biomarkers: Why Are They Important?

Biomarkers: Why Are They Important?

Biomarkers are body features that can be measured. There is, therefore, your blood pressure is a biomarker. For medicine in general, bio-markers are very important. We are all accustomed to see the doctor and get our test results – X-ray results or CAT scans – rightly and even imaging – and those are bio-markers that show how the body is doing, and they are measurable.


Biomarkers are essential for the development of drugs; they are very critical because during clinical trials we need to measure the effects of research medication on people. And the way we do this is to examine how biomarkers are affected. Therefore it is important for us to be able to measure all that we wish to know about the impact of research drugs on people with a wide range of biomarkers.

There are many problems in drug development today and the main problem is the failure rate. Even drugs which passed the entire preclinical process and underwent all types of animal testing and all types of testing, once they get into people, may have a chance of actually entering the market of less than 1 in 10.

During this development, nine out of 10 may fail. And we must do better if we are going to speed up the availability of treatment, if we are going to reduce and not increase the cost of drug development, and if we actually have a lot of innovators in this area of drug development.

We need a whole new generation of biomarkers to improve the success rate and the efficiency of the development of drugs and to tell developers early if they have toxicity or can not really work and to learn what will happen at an earlier date. And so the biomarkers are still to be developed.
