About this study

Official title: Implementation and Evaluation of Preemptive Pharmacogenomics Testing in an Aging Population

The primary goal of this study is to conduct pharmacogenomics testing (a type of DNA test) within an aging population and measure the impact of this test on medication selection, dosing, and costs of care.

Read the detailed description

Pharmacogenomics is the study of how a patient's unique DNA may interact with medications that the patient currently takes or may take in the future. DNA may change how a patient reacts to a medication, such as changing how well it works or the side effects. Knowing a patient's DNA profile may help healthcare professionals select the best medication treatment plan to use. This could include selecting the best medication to give or the medication strength that will work best for the patient. Currently, there is no standard that helps healthcare professionals decide to order a pharmacogenomics test that includes multiple genes. The investigators of this study think that having these DNA results in the medical record for participants who are at least 65 years old and are taking 5 or more medications will result in better health since healthcare professionals may use these results for treatment planning. Knowing if this is true will help healthcare professionals decide if ordering this test will improve patient health.

This study seeks to recruit participants for a pharmacogenomic study who visit at Geisinger 65 Forward locations. Patients who meet the study requirements and consent to be enrolled in this study will be randomly put into a group that receives this pharmacogenomics test or a group that does not receive it. There is a 50% chance of being put in the group that receives this pharmacogenomics test. The investigators will follow all patients enrolled in this study as they visit with their healthcare providers in the future. Geisinger healthcare professionals will have access to the results of this test in the medical record.

    This multigene pharmacogenomics test will report genetic variation for genes that have Clinical Pharmacogenetics Implementation Consortium (CPIC) guidelines.

Study groups in NCT05091879
Study groupRoleWhat they receive
Standard of CareNo interventionA multigene pharmacogenomics test will not be ordered for patients in this study arm, as is the standard of care.
Pharmacogenomics TestingExperimentalPatients in the experimental arm will be ordered a multigene pharmacogenomics test. This DNA test requires a blood draw, with the results expected to be reported in the medical record approximately 7 to 14 calendar days after the blood draw. These results will be made available to Geisinger healthcare professionals that have a treatment relationship with study participants.
Receives: Genetic: Multigene pharmacogenomics test

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of pharmacogenomic results returned in patients' health records

    The primary objective will be assessed by comparing the total number of patients with returned results in the electronic health record (EHR) with the total number of tested patients.

    Measured: Date of blood draw to test results reported in medical record, up to 1 month

Secondary outcomes (4)
  1. Composite of changes to medication therapy

    The number of medication changes (e.g. dose or agent change) that healthcare professionals initiate due to pharmacogenomics return of results.

    Measured: Date of test results reported to end of study, up to 5 years

  2. Costs of clinical care

    The total healthcare costs of patients.

    Measured: Date of test results reported to end of study, up to 5 years

  3. Medical costs of care

    Measure of the costs of medical care (e.g. hospitalizations, outpatient visits, etc.), excluding pharmacy services.

    Measured: Date of test results reported to end of study, up to 5 years

  4. Pharmacy costs of care

    Measure of the costs of all pharmacy services (e.g. medications, consults, etc.).

    Measured: Date of test results reported to end of study, up to 5 years

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of pharmacogenomic results returned in patients' health records (time frame: Date of blood draw to test results reported in medical record, up to 1 month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05091879, which also lists 12 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jun 2026.
