    BACKGROUND: Despite the increased demand for pharmacogenetic (PGx) testing to guide antidepressant use, little is known about how to implement testing in clinical practice. Best-worst scaling (BWS) is a stated preferences technique for determining the relative importance of alternative scenarios and is increasingly being used as a healthcare assessment tool, with potential applications in implementation research. We conducted a BWS experiment to evaluate the relative importance of implementation factors for PGx testing to guide antidepressant use. METHODS: We surveyed 17 healthcare organizations that either had implemented or were in the process of implementing PGx testing for antidepressants. The survey included a BWS experiment to evaluate the relative importance of Consolidated Framework for Implementation Research (CFIR) constructs from the perspective of implementing sites. RESULTS: Participating sites varied on their PGx testing platform and methods for returning recommendations to providers and patients, but they were consistent in ranking several CFIR constructs as most important for implementation: patient needs/resources, leadership engagement, intervention knowledge/beliefs, evidence strength and quality, and identification of champions. CONCLUSIONS: This study demonstrates the feasibility of using choice experiments to systematically evaluate the relative importance of implementation determinants from the perspective of implementing organizations. BWS findings can inform other organizations interested in implementing PGx testing for mental health. Further, this study demonstrates the application of BWS to PGx, the findings of which may be used by other organizations to inform implementation of PGx testing for mental health disorders.

    Establishing the value of genomics in medicine: the IGNITE Pragmatic Trials Network.
    (Springer, 2021-07) Ginsburg, Geoffrey S.; Cavallari, Larisa H.; Chakraborty, Hrishikesh; Cooper-DeHoff, Rhonda M.; Dexter, Paul R.; Eadon, Michael T.; Ferket, Bart S.; Horowitz, Carol R.; Johnson, Julie A.; Kannry, Joseph; Kucher, Natalie; Madden, Ebony B.; Orlando, Lori A.; Parker, Wanda; Peterson, Josh; Pratt, Victoria M.; Rakhra-Burris, Tejinder K.; Ramos, Michelle A.; Skaar, Todd C.; Sperber, Nina; Steen-Burrell, Kady-Ann; Van Driest, Sara L.; Voora, Deepak; Wiisanen, Kristin; Winterstein, Almut G.; Volpi, Simona
    PURPOSE: A critical gap in the adoption of genomic medicine into medical practice is the need for the rigorous evaluation of the utility of genomic medicine interventions. METHODS: The Implementing Genomics in Practice Pragmatic Trials Network (IGNITE PTN) was formed in 2018 to measure the clinical utility and cost-effectiveness of genomic medicine interventions, to assess approaches for real-world application of genomic medicine in diverse clinical settings, and to produce generalizable knowledge on clinical trials using genomic interventions. Five clinical sites and a coordinating center evaluated trial proposals and developed working groups to enable their implementation. RESULTS: Two pragmatic clinical trials (PCTs) have been initiated, one evaluating genetic risk APOL1 variants in African Americans in the management of their hypertension, and the other to evaluate the use of pharmacogenetic testing for medications to manage acute and chronic pain as well as depression. CONCLUSION: IGNITE PTN is a network that carries out PCTs in genomic medicine; it is focused on diversity and inclusion of underrepresented minority trial participants; it uses electronic health records and clinical decision support to deliver the interventions. IGNITE PTN will develop the evidence to support (or oppose) the adoption of genomic medicine interventions by patients, providers, and payers.

    (Wiley, 2022-07-28) Cavallari, Larisa H.; Cicali, Emily; Wiisanen, Kristin; Fillingim, Roger B.; Chakraborty, Hrishikesh; Myers, Rachel A.; Blake, Kathryn V.; Asiyanbola, Bolanle; Baye, Jordan F.; Bronson, Wesley H.; Cook, Kelsey J.; Elwood, Erica N.; Gray, Chancellor F.; Gong, Yan; Hines, Lindsay; Kannry, Joseph; Kucher, Natalie; Lynch, Sheryl; Nguyen, Khoa A.; Obeng, Aniwaa Owusu; Pratt, Victoria M.; Prieto, Hernan A.; Ramos, Michelle; Sadeghpour, Azita; Singh, Rajbir; Rosenman, Marc; Starostik, Petr; Thomas, Cameron D.; Tillman, Emma; Dexter, Paul R.; Horowitz, Carol R.; Orlando, Lori A.; Peterson, Josh F.; Skaar, Todd C.; Van Driest, Sara L.; Volpi, Simona; Voora, Deepak; Parvataneni, Hari K.; Johnson, Julie A.
    Opioid prescribing for postoperative pain management is challenging because of inter-patient variability in opioid response and concern about opioid addiction. Tramadol, hydrocodone, and codeine depend on the cytochrome P450 2D6 (CYP2D6) enzyme for formation of highly potent metabolites. Individuals with reduced or absent CYP2D6 activity (i.e., intermediate metabolizers [IMs] or poor metabolizers [PMs], respectively) have lower concentrations of potent opioid metabolites and potentially inadequate pain control. The primary objective of this prospective, multicenter, randomized pragmatic trial is to determine the effect of postoperative CYP2D6-guided opioid prescribing on pain control and opioid usage. Up to 2020 participants, age ≥8 years, scheduled to undergo a surgical procedure will be enrolled and randomized to immediate pharmacogenetic testing with clinical decision support (CDS) for CYP2D6 phenotype-guided postoperative pain management (intervention arm) or delayed testing without CDS (control arm). CDS is provided through medical record alerts and/or a pharmacist consult note. For IMs and PM in the intervention arm, CDS includes recommendations to avoid hydrocodone, tramadol, and codeine. Patient-reported pain-related outcomes are collected 10 days and 1, 3, and 6 months after surgery. The primary outcome, a composite of pain intensity and opioid usage at 10 days postsurgery, will be compared in the subgroup of IMs and PMs in the intervention (n = 152) versus the control (n = 152) arm. Secondary end points include prescription pain medication misuse scores and opioid persistence at 6 months. This trial will provide data on the clinical utility of CYP2D6 phenotype-guided opioid selection for improving postoperative pain control and reducing opioid-related risks.

    Implementing a pragmatic clinical trial to tailor opioids for chronic pain on behalf of the IGNITE ADOPT PGx investigators
    (Wiley, 2024) Skaar, Todd C.; Myers, Rachel A.; Fillingim, Roger B.; Callaghan, John T.; Cicali, Emily; Eadon, Michael T.; Elwood, Erica N.; Ginsburg, Geoffrey S.; Lynch, Sheryl; Nguyen, Khoa A.; Obeng, Aniwaa Owusu; Park, Haesuk; Pratt, Victoria M.; Rosenman, Marc; Sadeghpour, Azita; Shuman, Saskia; Singh, Rajbir; Tillman, Emma M.; Volpi, Simona; Wiisanen, Kristin; Winterstein, Almut G.; Horowitz, Carol R.; Voora, Deepak; Orlando, Lori; Chakraborty, Hrishikesh; Van Driest, Sara; Peterson, Josh F.; Cavallari, Larisa A.; Johnson, Julie A.; Dexter, Paul R.; IGNITE Pragmatic Trials Network; Medicine, School of Medicine
    Chronic pain is a prevalent condition with enormous economic burden. Opioids such as tramadol, codeine, and hydrocodone are commonly used to treat chronic pain; these drugs are activated to more potent opioid receptor agonists by the hepatic CYP2D6 enzyme. Results from clinical studies and mechanistic understandings suggest that CYP2D6-guided therapy will improve pain control and reduce adverse drug events. However, CYP2D6 is rarely used in clinical practice due in part to the demand for additional clinical trial evidence. Thus, we designed the ADOPT-PGx (A Depression and Opioid Pragmatic Trial in Pharmacogenetics) chronic pain study, a multicenter, pragmatic, randomized controlled clinical trial, to assess the effect of CYP2D6 testing on pain management. The study enrolled 1048 participants who are taking or being considered for treatment with CYP2D6-impacted opioids for their chronic pain. Participants were randomized to receive immediate or delayed (by 6 months) genotyping of CYP2D6 with clinical decision support (CDS). CDS encouraged the providers to follow the CYP2D6-guided trial recommendations. The primary study outcome is the 3-month absolute change in the composite pain intensity score assessed using Patient-Reported Outcomes Measurement Information System (PROMIS) measures. Follow-up will be completed in July 2024. Herein, we describe the design of this trial along with challenges encountered during enrollment.

Max; Rowe, Elizabeth; Blake, Kathryn V.; Limdi, Nita A.; Aquilante, Christina L.; Bates, Jill; Beitelshees, Amber L.; Cipriani, Amber; Duong, Benjamin Q.; Empey, Philip E.; Formea, Christine M.; Hicks, J.

    There is growing interest in utilizing pharmacogenetic (PGx) testing to guide antidepressant use, but there is lack of clarity on how to implement testing into clinical practice. We administered two surveys at 17 sites that had implemented or were in the process of implementing PGx testing for antidepressants. Survey 1 collected data on the process and logistics of testing. Survey 2 asked sites to rank the importance of Consolidated Framework for Implementation Research (CFIR) constructs using best-worst scaling choice experiments. Of the 17 sites, 13 had implemented testing and four were in the planning stage. Thirteen offered testing in the outpatient setting, and nine in both outpatient/inpatient settings. PGx tests were mainly ordered by psychiatry (92%) and primary care (69%) providers. CYP2C19 and CYP2D6 were the most commonly tested genes. The justification for antidepressants selected for PGx guidance was based on Clinical Pharmacogenetics Implementation Consortium guidelines (94%) and US Food and Drug Administration (FDA; 75.6%) guidance. Both institutional (53%) and commercial laboratories (53%) were used for testing. Sites varied on the methods for returning results to providers and patients. Sites were consistent in ranking CFIR constructs and identified patient needs/resources, leadership engagement, intervention knowledge/beliefs, evidence strength and quality, and the identification of champions as most important for implementation. Sites deployed similar implementation strategies and measured similar outcomes. The process of implementing PGx testing to guide antidepressant therapy varied across sites, but key drivers for successful implementation were similar and may help guide other institutions interested in providing PGx-guided pharmacotherapy for antidepressant management.

    Multisite investigation of strategies for the clinical implementation of pre-emptive pharmacogenetic testing
    (Elsevier, 2021) Duarte, Julio D.; Dalton, Rachel; Elchynski, Amanda L.; Smith, D. Max; Cicali, Emily J.; Lee, James C.; Duong, Benjamin Q.; Petry, Natasha J.; Aquilante, Christina L.; Beitelshees, Amber L.; Empey, Philip E.; Johnson, Julie A.; Obeng, Aniwaa Owusu; Pasternak, Amy L.; Pratt, Victoria M.; Ramsey, Laura B.; Tuteja, Sony; Van Driest, Sara L.; Wiisanen, Kristin; Hicks, J. Kevin; Cavallari, Larisa H.; IGNITE Network Pharmacogenetics Working Group; Medical and Molecular Genetics, School of Medicine
    Purpose: The increased availability of clinical pharmacogenetic (PGx) guidelines and decreasing costs for genetic testing have slowly led to increased utilization of PGx testing in clinical practice. Pre-emptive PGx testing, where testing is performed in advance of drug prescribing, is one means to ensure results are available at the time of prescribing decisions. However, the most efficient and effective methods to clinically implement this strategy remain unclear. Methods: In this report, we compare and contrast implementation strategies for pre-emptive PGx testing by 15 early-adopter institutions. We surveyed these groups, collecting data on testing approaches, team composition, and workflow dynamics, in addition to estimated third-party reimbursement rates. Results: We found that while pre-emptive PGx testing models varied across sites, institutions shared several commonalities, including methods to identify patients eligible for testing, involvement of a precision medicine clinical team in program leadership, and the implementation of pharmacogenes with Clinical Pharmacogenetics Implementation Consortium guidelines available. Finally, while reimbursement rate data were difficult to obtain, the data available suggested that reimbursement rates for pre-emptive PGx testing remain low. Conclusion: These findings should inform the establishment of future implementation efforts at institutions considering a pre-emptive PGx testing program.

    Rationale and design for a pragmatic randomized trial to assess gene-based prescribing for SSRIs in the treatment of depression
    (Wiley, 2024) Hines, Lindsay J.; Wilke, Russell A.; Myers, Rachel; Mathews, Carol A.; Liu, Michelle; Baye, Jordan F.; Petry, Natasha; Cicali, Emily J.; Duong, Benjamin Q.; Elwood, Erica; Hulvershorn, Leslie; Nguyen, Khoa; Ramos, Michelle; Sadeghpour, Azita; Wu, R. Ryanne; Williamson, Lloyda; Wiisanen, Kristin; Voora, Deepak; Singh, Rajbir; Blake, Kathryn V.; Murrough, James W.; Volpi, Simona; Ginsburg, Geoffrey S.; Horowitz, Carol R.; Orlando, Lori; Chakraborty, Hrishikesh; Dexter, Paul; Johnson, Julie A.; Skaar, Todd C.; Cavallari, Larisa H.; Van Driest, Sara L.; Peterson, Josh F.; IGNITE Pragmatic Trials Network; Psychiatry, School of Medicine
    Specific selective serotonin reuptake inhibitors (SSRIs) metabolism is strongly influenced by two pharmacogenes, CYP2D6 and CYP2C19. However, the effectiveness of prospectively using pharmacogenetic variants to select or dose SSRIs for depression is uncertain in routine clinical practice. The objective of this prospective, multicenter, pragmatic randomized controlled trial is to determine the effectiveness of genotype-guided selection and dosing of antidepressants on control of depression in participants who are 8 years or older with ≥3 months of depressive symptoms who require new or revised therapy. Those randomized to the intervention arm undergo pharmacogenetic testing at baseline and receive a pharmacy consult and/or automated clinical decision support intervention based on an actionable phenotype, while those randomized to the control arm have pharmacogenetic testing at the end of 6-months. In both groups, depression and drug tolerability outcomes are assessed at baseline, 1 month, 3 months (primary), and 6 months. The primary end point is defined by change in Patient-Reported Outcomes Measurement Information System (PROMIS) Depression score assessed at 3 months versus baseline. Secondary end points include change inpatient health questionnaire (PHQ-8) measure of depression severity, remission rates defined by PROMIS score < 16, medication adherence, and medication side effects. The primary analysis will compare the PROMIS score difference between trial arms among those with an actionable CYP2D6 or CYP2C19 genetic result or a CYP2D6 drug-drug interaction. The trial has completed accrual of 1461 participants, of which 562 were found to have an actionable phenotype to date, and follow-up will be complete in April of 2024.
