OMAHA, Neb.–Transgenomic, Inc. announced the launch of two innovative genetic tests at the annual meeting of the American Heart Association in Orlando, Florida. The PGxPredict:CLOPIDOGREL Panel is a uniquely comprehensive test to predict a patient’s response to clopidogrel (Plavix®). The company has also expanded its FAMILION family of tests for inherited heart diseases with the addition of a test for familial atrial fibrillation (AF).

Clopidogrel (Plavix®) is a widely prescribed antiplatelet drug used to reduce the risks of death, stroke, and heart attack in heart disease patients and to prevent blood clots in individuals who have recently received stents to widen blocked or narrowed arteries. About half of patients have dysfunctional versions of two genes responsible for absorbing clopidogrel into the bloodstream and then activating the drug, which puts these patients at an elevated risk of adverse outcomes. For these patients, clopidogrel may not work effectively at recommended doses.

The seriousness of this problem led the FDA in 2010 to add a black box warning to clopidogrel’s label to alert physicians and patients about this risk for the gene CYP2C19. The other gene, ABCB1, which is covered by a pending patent owned by Transgenomic, has been repeatedly confirmed as an independent risk factor for poor response to clopidogrel. Transgenomic’s PGxPredict:CLOPIDOGREL Panel is the only clopidogrel genetic panel on the market that assays both genes critical for understanding a patient’s individual response to this life-saving drug.

“With clopidogrel being one of the world’s most prescribed drugs, the opportunity to offer this critically important combination of these two genes to the general cardiology community represents a tremendous growth opportunity for our Clinical Laboratories division,” said Craig Tuttle, Chief Executive Officer at Transgenomic. “Current clopidogrel tests only look at the CYP2C19 marker leaving the approximately 25% of patients with reduced ABCB1 function at risk. The PGxPredict:CLOPIDOGREL Panel is unique since it detects genetic markers in both ABCB1 and CYP2C19, which together identify roughly 50% of patients with a genetic deficiency impacting their response to clopidogrel.”

“The use of the PGxPredict:CLOPIDOGREL Panel by the general cardiologist is an excellent opportunity for those physicians to develop an understanding of the value of genetic testing in their patients,” added Martin Maron, M.D., Director of the Hypertrophic Cardiomyopathy Center (HCM) at Tufts University. “As the general cardiologist becomes more comfortable with genetic testing, they have a real opportunity to impact patient outcomes by earlier detection of conditions like HCM and other cardiomyopathies.”

The FAMILION Familial Atrial Fibrillation (AF) Test is the newest addition to Transgenomic’s menu of genetic tests for inherited cardiac diseases. AF is a common abnormal heart rhythm that predisposes patients to stroke and typically occurs as the result of an underlying cardiovascular disease, such as heart failure or coronary artery disease. AF may also occur independent of other diseases, which is known as lone or familial AF, and can result from mutations in genes important for maintaining normal heart rhythm.

“Around one-third of AF patients have a family history of AF,” said Michael Gollob, M.D., Director of both the Inherited Arrhythmia Clinic and the Arrhythmia Research Laboratory at the University of Ottawa Heart Institute. “The availability of a genetic test for familial AF provides a new and important screening modality for family members who may be at risk of AF, and will provide us insight as to which family members will benefit from enhanced medical surveillance. This strategy will likely lead to earlier initiation of therapy for stroke prevention and rhythm control. Ultimately, we may learn that specific genetic sub-types of AF behave differently clinically in the context of stroke risk and pharmacologic response.”

About the PGxPredict:CLOPIDOGREL Panel

The PGxPredict:CLOPIDOGREL Panel analyzes the genes CYP2C19 and ABCB1 to help predict a patient’s response to clopidogrel (Plavix®), a widely used antiplatelet drug. The test results can be used to aid clinicians in developing a treatment plan for their patients being considered for or receiving clopidogrel.

About the FAMILION Tests

The FAMILION family of tests detects genetic mutations that can cause cardiac channelopathies, cardiomyopathies, and other cardiopathies. Cardiac channelopathies are rare, potentially lethal inherited heart conditions, including Long QT Syndrome (LQTS), Brugada Syndrome (BrS), Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT), Familial Atrial Fibrillation (Familial AF) and Short QT Syndrome (SQTS). Cardiomyopathies are potentially lethal progressive diseases that affect the heart muscle including, Hypertrophic Cardiomyopathy (HCM), Dilated Cardiomyopathy (DCM), Conduction Disease associated with DCM (CD-DCM), and Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC). Other cardiopathies include Marfan Syndrome and familial Thoracic Aortic Aneurysms and Aortic Dissections (Marfan/TAAD).

For patients suspected of having an inherited cardiac disease, genetic testing can confirm the diagnosis, provide valuable risk stratification information, guide treatment decisions, identify presymptomatic or silent carriers and better enable genetic counseling.
