Gene patenting -- steep cost for health care and patientsMay 08, 2007The drug trastuzumab (Herceptin) is used to treat HER2-positive breast cancer (a type of breast cancer that overexpresses the HER2 gene and accounts for about 25% of all breast cancers). Trastuzumab therapy improves the chances of survival; however, it has deleterious side effects and is expensive. Thus, it is important to accurately determine the patient's HER2 status. The challenge is to develop a testing strategy that is both accurate and economical. A false-negative test result can mean a woman will not receive a life-prolonging drug, and a false-positive result can lead to unnecessary, expensive drug treatment. In this systematic review, Dendukuri and colleagues compared the cost-effectiveness of 7 strategies (based on a combination of 2 tests) to diagnose HER2 status. They found that the most cost-effective strategy is to screen all women who have newly diagnosed breast cancer with immunohistochemistry and to confirm ambiguous or positive test scores with fluorescence in situ hybridization. In a related commentary, Brian Goldman notes that the example of trastuzumab and the HER2 gene illustrates both the promise and the perils of gene patenting. Even though genes occur naturally in humans, it is the person who discovers a gene who usually holds the patent for it.
Any researcher or pharmaceutical company who wants to investigate or develop treatments based on that gene must obtain permission from the patent holder. Even testing for mutations in patented genes (e.g., BRCA1 and BRCA2) can be restricted by the patent holder. Canadian Medical Association Journal | |||||||||||||||||||

Related Gene Patenting Current Events and Gene Patenting News Articles THE LANCET Neurology September Issue PRESS RELEASE THE GENETICS OF MIGRAINE Migraine is a very common neurological disorder affecting 15% of people from western populations. However, the mechanisms that cause migraine are poorly understood. Studies of families with migraine have identified a number of genetic loci that may have some role in the development of migraine. Anne Ducros (Hopital Lariboisiere, Paris, France) and colleagues review research on the genetics of migraine, the problems with identifying genes involved, and the possible mechanisms by which mutations in genes that encode ion channels may cause the attacks. Gene patenting-diagnosing the problem The US Patent and Trademark Office is currently processing patent applications fo Nuffield Council on Bioethics urges caution on patenting DNA Patents involving DNA sequences should be the exception rather than the rule, according to a paper published today (23 July) by the Nuffield Council on Bioethics. The Discussion Paper, The ethics of patenting DNA, recommends a number of significant changes to the way that patents are granted involving DNA sequences. The Discussion Paper, prepared by an international group of experts, proposes an ethical framework for gene patenting with recommendations aimed at policy-makers, courts, patent lawyers and patent offices. "We are concerned that, for patents involving DNA, the patent system is in danger of not achieving its main goal - to stimulate innovation for the public good.
