1000 Genomes, Clan Genomics and Cancer Biomarkers

The publication of human genome blueprint in 2000 was a great block party, summer Olympics coming to town, but the next morning saw most revelers picking up their drunken selves and going back to their old day jobs.  Some kept the flames burning by taking up more and more sequencing of whatever came their way labeled as a model organism.  The human genome blueprint was like a great idea which won a patent but still needed a lot of development work to morph into a cool product.

Post-human genome project

The launching of the 1000 Genomes Project in January 2008 was a true effort to translate the human genome blueprint into something that can really impact clinical practice and health care on a national scale.  The 1000 Genome Project was designed to sequence and catalog genetic variations from different ethnic groups across the globe.  The results of the pilot phase were published in Nature last year.

Shaping Cancer Diagnosis: Looking at the Horizon of Next Generation Sequencing and Targeted Resequencing

Two articles in this week's issue of Genetic Engineering & Biotechnology News reviewed recent trends in the next-generation sequencing and targeted resequencing technologies.  These advances are expected to further impact cancer diagnostics and treatment decision-making.

GNE Video: Understanding Biomarkers

Friday Grand Rounds are back, a day early because Jeff just flew in and can't wait to tell us all about Biomarkers. 

The Four Percent Lung Cancer Solution

A small group of lung cancer patients, who carry EML4-ALK marker in their tumor genome, can now look forward to a cancer-free future, thanks to a new drug crizotinib being developed by Pfizer.  This group of patients are generally nonsmokers or had given up smoking long ago, but still have the misfortune of coming down with lung cancer. 

Webinar Report: Impact of Next Generation/Whole-Genome Sequencing on Companion Diagnostics

Biomarkers are increasingly part of pharmaceutical and clinical strategy.  By some estimates, the success rate of FDA approval of new cancer drugs is 75% if mechanism-of-action and predictive or prognostic biomarkers are clearly defined, whereas it is 25% without the biomarker information.  However, identifying new biomarkers for companion diagnosis (CDx) remains a challenge—the identification of KRAS-type biomarkers is rare, there is a double regulatory hurdle and revenue issues hamper pharmaceutical investment in this area.  Whole-genome sequencing is an important tool in the discovery of biomarkers. 

Diagnostic Trailblazers in San Diego Advancing CDx, PGx and PM Goals in Cancer

Yesterday, I attended a half day symposium on companion diagnostics (CDx) efforts in San Diego which was organized by the SABPA Science & Technology Forum.  CDx is the identification and detection of biomarkers to predict whether a drug will work or not in a given patient.  Two successful marketed products are HercepTest (marketed by Dako) for Herceptin and KRAS tests for Erbitux and Vectibix.  San Diego biotech has a rich history and deep investments in diagnostics.  This was reflected in the lineup of various talks.
