The latest news from OneOme

OneOme comments on FDA’s Table of Pharmacogenetic Associations

On February 20, FDA released a Table of Pharmacogenetic Associations (updated February 25) and opened a docket for gathering feedback and comments.

As a leader in the pharmacogenetics (PGx) space, OneOme believes this is a positive step toward achieving consensus evidentiary standards for PGx testing. Our intent in providing the following comments was to help move toward this consensus by offering constructive feedback using our team’s extensive experience in evaluation of PGx evidence and our practical knowledge of how clinicians use PGx testing in patient care.*


OneOme appreciates FDA's move to further precision medicine as well as the opportunity to review and provide feedback on the Table of Pharmacogenetic Associations. The following comments are intended to promote development and consensus around evidentiary standards and best practices in pharmacogenomics ("PGx").

General feedback

  • OneOme requests FDA publish the level of evidence criteria that was required for inclusion in each of Tables 1, 2 and 3, including requirements around demographics and in vitro and in vivo data, as well as how FDA assessed and reconciled limitations of the studies reviewed. Clarifying how FDA defines "sufficient scientific evidence" will help healthcare practitioners evaluate lab-developed PGx tests and laboratories assure their gene-drug associations meet FDA's standards.
  • OneOme recognizes the challenges large organizations and regulatory agencies have in maintaining updates to their publications every time new, impactful research is published. However, citations are important to help providers understand what information was considered by FDA and therefore reconcile any differences between new or other existing data that may be applicable to patient care and the practice of medicine.
  • OneOme has concerns that the lack of transparency around criteria for inclusion and absence of specific guidance from FDA related to PGx abrogates the clinical utility of this table. Moreover, it is likely that this will be misinterpreted by patients and providers as FDA's official guidance on PGx testing.

Specific feedback

Critical omissions: Phenytoin and HLA-B*15:02 and CYP2C9

Phenytoin (PHT) is metabolized by CYP2C9. Studies have associated the *3 allele with increased risk of severe cutaneous adverse reactions, particularly in patients of Chinese and Thai descent. Poor CYP2C9 metabolism of phenytoin is associated with increased plasma concentrations and probability of toxicity. The Clinical Pharmacogenetics Implementation Consortium (CPIC) and Dutch Pharmacogenetics Working Group (DPWG) have published specific guidelines regarding this association.1,2 In addition, CPIC, FDA, and the Canadian Pharmacogenomics Network for Drug Safety (CPND) noted that presence of the HLA-B*15:02 allele is associated with the risk of developing Stevens-Johnson Syndrome (SJS)/Toxic epidermal necrolysis (TEN).1,3,4 The high frequency of HLA-B*15:02 in Chinese, Thai, Taiwanese, and Indonesian populations (4%-36%) means it is important to note the risk of PHT-associated SJS/TEN in patients carrying this allele.

Confusing category assignments

FDA presented three tables, describing only the first as being supportive of therapeutic management recommendations. The rationale and practical implications of FDA's categorical divisions are unclear at the outset and become more so when, for example, citalopram and escitalopram are categorized separately, in Tables 1 and 3, respectively.

Citalopram is a racemic mixture in which the S-enantiomer, escitalopram, is the active component (167x more active than the R-enantiomer4) and favored target of CYP-mediated metabolism (CYP2C19, -3A4, and -2D6).5,6 Given the adverse drug event (ADE) and efficacy data available for citalopram, the pharmacokinetic data alone, which FDA acknowledges by inclusion of escitalopram in Table 3, should be sufficient to support the use of CYP2C19 PGx in therapeutic management with escitalopram and thus its inclusion in Table 1. The FDA tables also note only the likelihood of increased systemic drug concentrations in poor metabolizers but ignore the substantial data available indicating the likelihood of reduced systemic drug concentrations and lack of efficacy in rapid and ultrarapid metabolizers (carriers of CYP2C19*17).2,7-9

The confusion lies with the implication that the contents of Table 3 have less supporting evidence than those in Table 1. The case of citalopram/escitalopram belies this demarcation, because the racemic mixture of R and S citalopram is comprised of 50% escitalopram. Given the level of data supporting increased ADE risk with the racemic mixture demonstrated by FDA's inclusion of citalopram in Table 1, additional in vivo studies of escitalopram would unnecessarily expose human subjects to increased risk without demonstrable benefit.


As FDA works on future drafts of the Table of Pharmacogenetic Associations, OneOme offers the following recommendations:

  • Collaborate with PGx experts in academia, industry, pharmacy, and clinical practice to achieve consensus on criteria and level of evidence for documented PGx associations.
  • Develop and share information on the timelines for reviewing new evidence and schedule for updating the Table.
  • Publish draft guidance for PGx testing to clarify how this table fits into FDA’s future plans regarding PGx.

Family Care Path Partners With OneOme To Add Pharmacogenomic Testing To Its Genetic Wellness Program

CLEVELAND and MINNEAPOLIS, Dec. 2, 2019 /PRNewswire/ -- Family Care Path, Inc. a health technology company that brings applications benefiting people to the healthcare market, today announced a new partnership with Minneapolis-based pharmacogenomic (PGx) solutions company, OneOme, LLC. Through this partnership, Family Care Path will be offering OneOme's RightMed® Test to its customers along with its MyLegacy application, a family history-based genetic risk assessment.

PGx is the study of how DNA may affect an individual's response to medications. OneOme's RightMed Test is a PGx test, co-developed with Mayo Clinic, that analyzes a person's DNA to give doctors and pharmacists genetic information that may help them optimize medication selection for that person, minimize trial and error in the prescribing process, decrease the likelihood of adverse drug reactions and reduce potential healthcare costs. And only individuals most likely to benefit from pharmacogenomic testing will actually be tested, using OneOme's proprietary population evaluation algorithm.

"OneOme's RightMed Test is an ideal complement to our MyLegacy application," said Dave McKee, President and CEO of Family Care Path. "This partnership brings a new and exciting dimension to our offering, while maintaining our focus on improving people's health outcomes while reducing healthcare costs."

My Legacy is a web-based application that collects, through a secure web-based portal, an individual's personal and family health history information to evaluate their genetic risk for actionable conditions. This allows for preventative healthcare before the person develops significant and potentially devastating diseases like cancer or cardiovascular disease. And by addressing the disease at this earlier state, provides the potential for reduction in cost of medical care.

Results of the RightMed Test and the MyLegacy genetic risk assessment will be reviewed with the individual by a Family Care Path genetic counselor through CarePathConnect, a video-based telegenetic service. Associated recommendations and reports will be provided to the person to share with their physician for treatment plan development.

"We are excited by the opportunity to add value to Family Care Path's My Legacy solution," said Patrick McIntyre, OneOme's CEO. "We believe this collaboration will showcase the benefits of pharmacogenomics – both for medication management and as part of a broader genomic wellness program."

OneOme And Walgreens Boots Alliance Subsidiary Alliance Healthcare Partner To Bring Personalized Prescriptions To The Netherlands

MINNEAPOLIS and 'S-HERTOGENBOSCH, Netherlands, Nov. 19, 2019 /PRNewswire/ -- OneOme today announced a pilot partnership with Alliance Healthcare Netherlands (a wholly owned subsidiary of Walgreens Boots Alliance) that will bring pharmacogenomic testing to selected Boots and Alphega Pharmacy locations throughout the Netherlands.

Pharmacogenomics (PGx) is the study of how DNA may affect individual response to medications. PGx testing analyzes a patient's DNA to give doctors and pharmacists information that may help them optimize medication selection for that patient, reduce trial and error in the prescribing process, potential healthcare costs and decrease the likelihood of adverse drug reactions.

"The OneOme team is thrilled to be partnering with Alliance Healthcare Netherlands. This is an organization that is committed to delivering exceptional patient care. We are excited to work with the pharmacists at pilot locations to provide medication optimization through pharmacogenomic insights," said Morgan Donaldson, Director of International Business Development for OneOme.

As part of the initial pilot, pharmacists at 18 Boots and Alphega Pharmacy locations in the Netherlands will be able to order OneOme's RightMed® comprehensive test* for their patients. Patients will be able to give their DNA sample in the pharmacy with a cheek swab. When the pharmacists get the patient's results, they will schedule a consultation with the patient, as well as reach out to the patient's general practitioner to discuss the results and how they may be relevant to the patient's medications.

The pilot phase of the partnership is intended to evaluate the feasibility of offering PGx testing in all Boots and Alphega retail pharmacy locations in the Netherlands, as well as to understand the impact on patient care. Manuel Voll, Director Alphega Pharmacies in the Netherlands, noted, "We look forward to working with OneOme to ensure a successful implementation and to capture important insights about how patients and pharmacies can benefit from the RightMed test."

OneOme's RightMed comprehensive test and report provide insights on 27 genes for 300 different medications, giving pharmacists and doctors valuable genetic information they can use to help optimize medication selection for their patients.
