Biomarker Bulletin: August 23, 2011

Reading time: 2 – 4 minutes

Biomarker Bulletin is an occasionally recurring update of news focused on biomarkers aggregated at BiomarkerCommons.org. Biomarkers are physical, functional or biochemical indicators of normal physiological or disease processes. The individualization of disease management — personalized medicine — is dependent on developing biomarkers that promote specific clinical domains, including early detection, risk, diagnosis, prognosis and predicted response to therapy.

• Biomarker Commons Named World Companion Diagnostics Summit Media Partner

  Diagnostics used to select patients for treatment with a particular therapeutic or determine what and/or how treatment will be administered have been termed companion diagnostics. Companion diagnostics hold great promise for personalized medicine. A companion diagnostic is a biomarker(s) used in a specific context that provides biological and/or clinical information that enables better decision making about the development and use of a potential therapeutic. Given the significance of companion diagnostics, I’m proud to announce Biomarker Commons’ first media partnership with the 4th World Companion Diagnostics Summit.

• Personalized Medicine or Patient-centered Care?

  Personalized medicine is a term used in science and medicine that holds significant promise of administering medicines specifically tailored to an individual’s genome or metabolism. However, an editorial published yesterday in the Canadian Medical Association Journal (CMAJ) suggests that the term creates an image for the public that is completely opposite of science and technology and sets up unrealistic expectations.

• FDA, EMA Seek Input on Companion Diagnostics, Genomic Biomarkers

  Regulators in the U.S. and Europe have each posted requests for public comment on issues affecting the development of medicines by drug companies.

• FDA Issues New Guidelines on Clinical and Nonclinical Genomic Biomarkers

  The U.S. Food and Drug Administration (FDA) has issued new guidelines on biomarkers related to drug or biotechnology product development. The guidance was developed within the Efficacy Working Group of the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH).

• Neuroimaging Identifies an Endophenotype and Candidate Biomarker for Autism

  In response to facial expression of emotional, a similar pattern of brain activity is observed in both people with autism and their unaffected siblings. Researchers from the University of Cambridge recently used functional magnetic resonance imaging (fMRI), a specialized MRI scan used to measure the change in blood flow related to neural activity in the brain, to show that reduced activity in areas of the brain associated with empathy and face processing is a candidate biomarker for familial risk of autism. The findings were published online recently in the journal Translational Psychiatry.
