Genetics and cardiovascular drugs: an interview with Nancy Lurker, CEO of PDI and Paul Kinnon, CEO of Transgenomic, Inc.

How do genetic variations affect cardiovascular drug effectiveness?

People inherit different versions of any particular gene, and some genes affect how patients process and metabolize medicines. This especially holds true for people with cardiovascular (CV) disease. They may be fast, slow or non-metabolizers and might also react badly (with serious adverse events) to certain drug therapies or not at all.

A large subset of cardiovascular disease patients (20-50%) respond poorly to “standard of care” medicines due to their genetic make-up. Adverse outcomes, including risk of CV death, myocardial infarction, or stroke have been demonstrated to align to the genetic makeup, or genotype, that the patient inherited. Historically, this response could not be predicted in advance of prescribing or taking a medication.

Please can you introduce the molecular diagnostic test that Transgenomic have developed to identify patients’ genes that may influence the effectiveness of cardiovascular drugs?

CardioPredictTM is a broad-based genetic assay that identifies a patient’s specific genes that influence the effectiveness and safety of many commonly used cardiovascular drugs such anti-coagulants (blood thinners) statins (cholesterol lowering drugs), beta blockers and antiarrhythmics.

This new molecular diagnostic test panel analyse more than 40 genetic markers in 10 genes shown to be important for predicting how individual patients may respond to a cardiovascular drug. The most common of these medications include clopidogrel, atorvastatin calcium, simvastatin, warfarin, and more.

CardioPredict is a very comprehensive commercially available test for predicting cardiovascular drug response, and the only one that includes the critical ABCB1 gene, shown to impact patients’ ability to absorb clopidogrel.

How does the test work?

CardioPredict(TM) Pharmacogenomic Optimization Panel provides healthcare professionals the ability to tailor cardiovascular treatment to an individual patient's genotype. 

DNA obtained within a buccal swab is analyzed to identify polymorphisms, or variations of a particular DNA sequence within genes.  CardioPredict(TM) assesses polymorphisms within 10 genes that correlate with cardiovascular drug responsiveness--ABCB1, CYP2C19, CYP2C9, VKORC1, CYP2D6, CYP3A4, CYP3A5, Factor V, Factor II, and MTHFR.

A customized patient report summarizes the results and provides a detailed pharmacogenomic profile that informs the healthcare professional of the patient's genetic predisposition towards absorption, activation, and metabolism of specific cardiovascular medications.  The report also provides clinical implications to help guide healthcare professionals in tailoring their treatment, including dose adjustments or use of alternative therapies that do not have genetic limitations.

How useful is this information to physicians who have to make drug selection and dosing decisions?

The availability of CardioPredict makes the knowledge of patients’ individual genetic makeup (related to these genes) available in broad commercial panel available for the first time, which can help in choosing drugs and dosing more effectively.

If a patient is found to possess certain genes variants, physicians can prescribe alternative therapies that are not as dependent on genetic limitations right away, rather than taking a ‘wait and see’ approach to selecting a treatment. The easy-to-interpret CardioPredict™ test results help physicians to individualize CV therapies for each of their at-risk patients to achieve optimal therapeutic benefits. The test will only need to be performed once to provide a lifetime of therapeutic guidance.

Transgenomic recently partnered with PDI, Inc. to commercialize this test. What are the next steps in this process?

We are introducing CardioPredict in a few key markets initially this year, and plan to make it fully available in the U.S. early in 2014. We have sales representatives in the field engaging with physicians regarding the test, which is being made available.

What impact do you think this test will have?

We believe that CardioPredict will enable to physicians to help better manage their at-risk patients, through this personalized approach to medicine, and accelerate the process of getting them on the right treatment.

What are PDI’s and Transgenomic’s plans for the future?

At PDI, we are focused on successfully commercializing CardioPredict and look forward to a mutually beneficial relationship with Transgenomic through our eight-year agreement and beyond to help address the growing population of high-risk patients with CV disease and the physicians that help treat them.

Do you have plans to develop similar tests for other types of drug?

PDI’s strategy involves plans to commercialize additional molecular diagnostic tests, although it is too early at this time to discuss them specifically.
