Extensive Scientific Data Supports the Clinical Validity of Pharmacogenomic Testing for Predicting Patient Response to Psychiatric Medications

Reading time: 2 – 3 minutes

AssureRx Health, a leading personalized medicine company, recently announced that the International Review of Psychiatry published an extensive review that validates the clinical use of pharmacogenomic testing to help predict patient response to psychiatric medications and improve treatment outcomes.

The paper provides substantial evidence that psychiatric pharmacogenomic testing has proven clinical value in predicting how individual patients will tolerate and respond to specific psychiatric medications. These findings refute results of a previous assessment of pharmacogenomic testing conducted in 2007 by the Evaluation of Genomic Applications in Practice and Prevention initiative (EGAPP) which concluded that there was insufficient evidence to determine the value of pharmacogenomic testing for adults beginning treatment with SSRI antidepressants.

The current article titled “Clinical Validity of Cytochrome P450 Metabolism and Serotonin Gene Variants in Psychiatric Pharmacotherapy” reviewed published data collected since 2007 examining how DNA sequence variations between individuals can affect their metabolism and response to medications. The preponderance of evidence from these studies supports the validity of analyzing patients’ genetic profile to predict the metabolism, safety, and therapeutic efficacy of psychotropic medications commonly used for the treatment of depression, schizophrenia, and bipolar disorder.

“A review of 294 scientific studies published since the EGAPP report clearly demonstrates the clinical validity of multiple genes in predicting patient responses to antidepressant medications. This assessment is further supported by multiple clinical trials demonstrating that understanding variations in these same genes leads to better treatment decisions and better patient outcomes,” said C. Anthony Altar, Ph.D., Chief Science Officer of Assurex Health and lead author.

“The review of these clinical and scientific data clearly reinforces the benefits of pharmacogenomic testing in aiding medication selection and augmenting patient responses to antidepressant and antipsychotic medications. Use of pharmacogenomic testing leads to earlier identification of optimal treatment protocols for individual patients,” said Assurex Health CEO James S. Burns. “The question is no longer whether pharmacogenomic testing is ready for routine clinical use; rather, how to make it available earlier in the course of patient treatment to improve patient outcomes.”
