New Genetic Tests play stronger role in targeting therapy
>Rod Raynovich Final for GEN 9/2/2008
Amidst the gloom and doom of the credit meltdown , biotech stocks offer a bright outlook as they are the best performing sector in 2008 and medical diagnostics is even hotter. Returns of 25% + are achievable YTD. The “Medical Genetics” subgroup is in the #1 position based on 6 month stock price performance among 197 companies according to September 2008 IBD (Investor’s Business Daily) data. I reviewed the molecular diagnostics sector in September 2006 and now with recent scientific and commercial developments in genetic testing and pharmacogenomics the technology will have a major long term impact on drug therapy.
A brief history:
- Back in the dark ages of biotechnology and molecular biology-the Seventies-several drug companies pursued the obvious synergy of diagnosis and therapy. Roche, SmithKline (now GSK), Abbott and JNJ and others had diagnostic divisions. Even Lilly jumped into the fray by buying Hybritech in the eighties at inflated prices as monoclonal antibodies were hot. The implied synergy faded as the biopharm a boom took hold in the eighties with ample financing for pure plays such as Amgen and Genentech.
- Meanwhile big pharma went off looking for multibillion dollar blockbusters to sell direct to the consumer (DTC) like Lipitor, Nexium and Plavix. Fast forward-now generics are a big threat so follow the science and money back to orphan drugs and diagnostics.
- In the late nineties, the field of genomics exploded with the mapping of the human genome. That megatheme produced the biotech stock market bubble of 1999 lead by Human Genome Sciences . However the idea that genes could be patented or that the genetic information would accelerate development of new drugs proved to be overly simplistic as the pace of new drug approvals has even slowed since then.
- Currently genomics tools have evolved to the clinical stage and will leverage the previous investment in genomics over the longer term.
New platform technologies and scientific breakthroughs applying vast amounts of genomic data have brought diagnostics to the forefront with the cogent idea that better diagnostics based on genetic information brings cost effective more targeted therapies.
Affymetrix and Illumina created innovative array based products that enabled high speed analysis of DNA,RNA and proteins as tools for disease research, drug development and molecular tests. These gene sequencing tools are being applied at an earlier stage betting that drug discovery can be made more productive by focusing on the genetic make-up of the patient population with the big promise of “personalized medicine”.
Genetic tests can optimize drug therapy for example the FDA recently approved a HER-2 test called SPOT-Light (InvitroGen) that can be used to identify breast cancer patients who are candidates for treatment with Herceptin (Roche). At a recent ASCO Meeting data was presented showing the importance of testing for the K-ras gene to assess the clinical benefit of Erbutux for metastatic colorectal cancer. The term “companion diagnostic” is being used to describe a test that is used to better define a patient’s need or clinical out come from a specific drug.
Of all the larger integrated healthcare companies, Roche has best executed the synergies of molecular diagnostics and biopharmaceuticals and is positioned well for the future with products in oncology and infectious disease. Their genetic tests include CYP450 for drug metabolism and HER-2 for information supportive with tamoxifen (Herceptin) therapy. Roche recently acquired Ventana Medical Systems a diagnostic system for anatomic pathology for about $3.5B.

The Luminex CF cystic fibrosis kit is on the market and a newborn screening panel is expected by Q4 2008.The Company recently announced that Abbott will distribute their xTAG Respiratory Viral Panel that can detect 12 viruses and subtypes. In the pharmaco genomics area a CytochromeP450 genotyping test is in development for drug metabolism assessment. Tyson Foods is their partner for food safety and animal health.
SQNM is one of the hottest genetic testing stocks of 2008 going from 5 in March to 22 in August. The Company translates genomic information into potential clinical utility with its MassARRAY DNA analysis platform beginning with its SEQureDx, technology for prenatal non-invasive, SNP-based genetic analysis starting with Down’s Syndrome. The test isolates and analyzes circulating fetal nucleic acid from a maternal blood sample and can be performed early in pregnancy. Clinical testing is underway.. The Company �s current revenue stream is primarily for MassARRAY iPlex Gold platform for SNP genotyping or sub-whole genome study applications.
Among the other SNP-based tests in the clinical pipeline include chromosomal disorders , and Prenatal tests for RhDisease, Autism and thalassemias. Molecular Diagnostic tests will be partnered and the menu includes cancer, HPV, Lupus and chronic kidney failure. APMA submission for RhD is estimated sometime in 2009.The Company already has a gang of bankers, hedge funds, analysts and traders who are enthusiastic about the stock especially for the Down Syndrome and other prenatal tests with potential in the “multibillion dollar range worldwide”according to the Company. Most of the current sales are for DNA analysis tools and revenue estimates are in the $50M range for 2008 with losses at 70 cents per share.
A new wave of molecular diagnostics platform companies are enter the commercial stage with technologies that translate genetic information to actionable clinical outcomes not only for cancer and infectious disease but cardiovascular and infectious disease and diabetes:

A recent short survey by Burrill and Co. and ChangeWave Research concluded that consumers are reluctant to undergo genetic test s for early warning about devastating illnesses. A “Personalized Medicine Meeting” will be held by Burrill in November 2008. Look to the American Society for Human Genetics on November 11-15 for additional scientific news on the sector.
According to Kalorama Information the Molecular Diagnostics market exceeds $3.2B Worldwide with breakthrough tests for infectious disease. SNP testing alone is approaching $1B. The market is forecasted to reach $5.4B by 2012 but $1.2B of this will be for blood screening. Bruce Cranna, analyst with Leerink Swann has coverage of Genomic Health and Nanophase among other s and estimates the current market for Inherited Diseases at $250M.From my perspective the growth should exceed current forecasts due to novel genomics platforms that create clinical utility and the importance of these tests to targeting therapy and overall decision support to physicians. Also the market data may not be capturing gene testing services so the estimates are probably low.
The application of genomic based diagnostics will have a major impact on therapies and there will be a shift in R&D investment from drugs to diagnostics.
Existing drivers for growth in the genomic testing market are:
- Need for molecular diagnostics in drug selection for cancer therapy is growing.
- More SNP’s tests advance to clinical diagnostic s utility e.g. CF and RhD.
- Pharmacogenomic studies show greater clinical utility for example response to Warfarin therapy that can be predicted by identifying alleles of the VKORC1 gene target.
- Drug discovery and development applies genomic tools and biomarkers earlier creating more “companion diagnostics”.
- Diagnostic testing becomes increasingly cost effective such as routine screening of newborns for Cystic Fibrosis.
- “Direct to Consumer” gene tests that identify disease risk factors although the field is at an early stage and lacking large scale clinical data .So called gene scans are still controversial.
