A Prospective Trial to Assess Cost and Clinical Outcomes of a Clinical Pharmacogenomic Program — INGenious  

Adverse Drug Reaction Clinical Trial

Official title: A Prospective Randomized Trial to Assess Cost and Clinical Outcomes of a Clinical Pharmacogenomic Program at Eskenazi Hospital

Status Completed

Clinical Trial Summary

The INGenious trial will prospectively enroll a total of 6,000 patients, with 2,000 patients assigned to a pharmacogenetic testing arm and 4,000 to a control arm who will be followed, but not tested. It is randomized between an intervention arm and one that receives no intervention in order that the genotyped group can be compared with one in which undisturbed, routine clinical care is carried out in patients taking the same drugs. Both arms will be followed for a year after being prescribed a targeted medication. Patients randomized into the intervention arm that are prescribed one or more of the 24 targeted index medication will receive pharmacogenomic testing using a custom micro-array measuring 51 Single nucleotide polymorphisms in 16 genes. The study is being conducted by the Indiana University School of Medicine and the Indiana University Institute of Personalized Medicine in collaboration with the Eskenazi and Indiana University Health Systems and will evaluate the economic and clinical outcomes associated with embedding a pharmacogenomics program in a system that serves as the primary health care safety-net in Indianapolis, Indiana. By successfully implementing a pharmacogenomics program and integrating it with the Electronic Health Record and Clinical Decision Support system, physicians will be able to optimize patient care by delivering tailored therapeutic decisions based on the patient's individual genetics.

Clinical Trial Description

Indiana University School of Medicine and the Indiana University Institute of Personalized Medicine in collaboration with the Eskenazi Health and IUH Systems will be conducting a NIH funded randomized trial beginning in 2014. The study will evaluate the economic and clinical outcomes of associated with embedding a pharmacogenomics program in a system that serves as a health care safety-net in Indianapolis, Indiana, and handles over 1.2 million outpatient visits a year at its hospital and network of 10 community health centers. There are over 990,000 outpatient visits and 15,000 adult admissions annually, and the payor mix includes 45% uninsured, 26% Medicaid and 18% Medicare patients. This health care system has more than 40 years of experience in digital medical record implementation and a proven track record of innovation in medical informatics that is based in the Regenstrief Institute.

The goal of Personalized Medicine (PM) is to implement advances in biomarker pharmacology, molecular diagnostics and genomics to improve the health of patients afflicted by a wide range of medical conditions. Dramatic advances in genomics have identified numerous disease/therapeutic associations now placing this goal within sight. For the full benefits of personalized genomic medicine to be realized, it is now critical that progress made on a small scale be extended. The fruits of outstanding scientific discovery are often enjoyed by a small number of academic medical centers but are not scalable, and therefore not available to the masses of patients found in larger health care systems. In addition, such advances often bypass underserved populations, resulting significant inequalities of care.

Study Aims:

Aim 1: To test the hypothesis that a Clinical Laboratory Improvement Amendment certified genotyping targeted at 24 widely used drugs is associated with significant reductions in hospital and outpatient economic costs incurred over 1 year.

Aim2: To test whether pharmacogenetic testing is associated with significant improvements in clinical outcomes over 1 year.

The INGENIOUS trial will enroll a total of 6,000 patients, with 2,000 patients assigned to a pharmacogenetic testing arm and 4,000 to a control arm who will be followed, but not tested. The study is prospective since practice patterns change, and retrospective designs cannot be used to assess the impact of a prospective change. It is randomized between an intervention arm and one that receives no intervention in order that a genotyped group can be compared with one in which undisturbed, routine clinical care is carried out in patients taking the same drugs. Both arms will be followed for a year. Subjects will be enrolled starting at 6 months into the funding period, and investigators will enroll subjects for a total of 2 years, so that the last person enrolled will be at 2.5 years, and follow up will be completed at 3.5 years, allowing 6 months for analysis at the end of the study. A pharmacogenetic test, involving 51 Single nucleotide polymorphisms in 16 genes will be carried out at the beginning of the study in patients in the testing arm upon prompting by an index medication: one of 24 selected as being supported by validated guidelines. ;
