Patent Describes Methods to Adjust Dosing of Psychotropic and Other Medications
Mason & Cincinnati, OH – December 2, 2013 – Cincinnati Children’s Hospital Medical Center (CCHMC) and Assurex Health today announced that the United States Patent and Trademark Office (USPTO) issued U.S. Patent No. 8,589,175 encompassing the “Optimization and Individualization of Medication Selection and Dosing” by Cincinnati Children’s inventors Drs. Tracy A. Glauser, Richard J. Wenstrup*, Alexander A. Vinks, and John P. Pestian. The CCHMC patent covers methods for optimizing dosing regimens for medications utilizing population models, genotype, and clinical information to treat patients with neuropsychiatric and other disorders. Assurex Health is the exclusive worldwide licensee of the technology covered under the CCHMC patent and has developed pharmacogenomic tests for psychiatric, ADHD, and pain medications commercialized under the GeneSight® brand.
The Cincinnati Children’s invention provides a mechanism for translating “one size fits all” drug dosing into individualized dosing based on a person’s genetic and non-heritable characteristics. The methods of the invention can be applied to correct for the variability seen in drug metabolism due to genetic polymorphisms combined with the variability resulting from non-genetic factors. The results provide a way to standardize the impact of various fixed factors, such as a patient’s genetic variability, and dynamic factors, such as drug-drug and drug-environment interactions or patient drug-adherence. As a result, the starting and target doses for neuropsychiatric and other medications can be determined without the need for metabolic data.
GeneSight is a unique pharmacogenomic treatment decision support tool that tests for clinically important genetic variants affecting a patient’s response to neuropsychiatric medications. Prescribing a medication that may be more likely to succeed because it is tailored to an individual patient’s genetic profile enables clinicians to better manage their patient’s condition and improve outcomes. For example, the recently published La Crosse clinical study showed a four-fold greater improvement in symptoms for patients whose medications were switched from their initial medications that were genetically discordant with their GeneSight profile. Furthermore, physicians for 94% of the GeneSight-guided patients either switched their patients to genetically appropriate medications or adjusted their medication dosages according to the GeneSight report.
“The Cincinnati Children’s patent represents a significant advance in pharmacogenomic-directed prescribing. The addition of dosing information to our GeneSight products will enhance their value as the premier treatment decision support products that help clinicians individualize the selection of psychotropic and other medications for their patients,” said James S. Burns, CEO of Assurex Health. “Assurex Health was founded to develop and commercialize cutting-edge pharmacogenomic research at CCHMC. The issuance of this dose selection patent represents another milestone in translating state-of-the-art pharmacogenomic products to support the treatment of patients with neuropsychiatric and other disorders.”
“Individualizing both the selection and dosing of medications will improve patient outcomes by providing objective, evidence-based information to tailor treatment programs,” said Tracy A. Glauser, M.D., Associate Director, Cincinnati Children’s Research Foundation and lead inventor on the CCHMC patent. “The issuance of this patent points to the importance of pharmacogenomic-directed prescribing and its potential to improve patient care in routine clinical practice.”

GeneSight is a laboratory-developed pharmacogenomic test that uses cutting edge technology to measure and analyze clinically important genomic variants in the treatment of psychiatric disorders. The results of the GeneSight report can help a clinician understand the way a patient’s unique genomic makeup may affect certain psychiatric drugs. The analysis is based on pharmacogenomics, the study of genomic factors that influence an individual’s response to drug treatments, manufacturers’ FDA approved drug labels, peer reviewed scientific and clinical publications, and proven drug pharmacology. Quick turnaround time, combined with a customized report of the patient’s genomic makeup, clinical experience, and other factors can provide information to help a physician make personalized drug treatment choices for each patient.
