Evaluating a Pharmacogenetic Testing Panel in Patients Suspected to be at Increased Risk for Pharmacogenetics-related AEs While Receiving Fluoropyrimidine or Irinotecan Therapy

May 6, 2025 updated by: University of Michigan Rogel Cancer Center

Evaluating the Uptake and Impact of a Pharmacogenetic Testing Panel in Patients Suspected to be at Increased Risk for Pharmacogenetics-related AEs While Receiving Fluoropyrimidine or Irinotecan Therapy

This study will be evaluating patients suspected to carry DPYD or UGT1A1 variants based off of Michigan Genomics Initiative (MGI) results. Standard of care treatment will be initiated with either Fluoropyrimidine or Irinotecan therapy. Retrospective collection of treatment related AEs and SAEs, dose delays, dose reductions, and treatment discontinuations will be completed.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Trial was registered as interventional as patients could be enrolled prospectively or retrospectively. Based on data received 2/3/2025, all 16 enrolled cases ended up being identified retrospectively. As the study is now considered to be only retrospective, the record has been updated as not an applicable clinical trial (ACT).

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
16

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

patients who have been retrospectively identified as any patient who had clinical genotype testing and had a variant that was their clinician used to guide the chemotherapy treatment.

Description

Inclusion Criteria:

  • Age > 18 years
  • Prospectively enrolled cases:

A. Suspected to carry an actionable DPYD phenotype per MGI and initiating treatment with systemic FP OR suspected to carry an actionable UGT1A1 phenotype per MGI and initiating treatment with irinotecan for cancer

B. The ability to understand and the willingness to sign a written informed consent.

  • Retrospective cases:

A. Confirmed actionable DPYD phenotype before treatment with systemic FP OR confirmed actionable UGT1A1 phenotype before treatment with irinotecan

B. Clinician initiated dose reduction of the fluoropyrimidine or irinotecan therapy based upon genotype result

  • Retrospective controls:

A. Suspected actionable DPYD phenotype per MGI and treatment with systemic FP OR suspected actionable UGT1A1 phenotype per MGI and treatment with irinotecan

Exclusion Criteria:

  • For prospective cases, prior treatment with systemic FP if suspected to carry an actionable DPYD phenotype
  • For prospective cases, prior treatment with irinotecan if suspected to carry an actionable UGT1A1 phenotype
  • For prospective cases, inability to understand consent or make health-related decisions
  • History of allogeneic bone marrow transplant prior to genotype testing
  • History of liver transplant

Design Details

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Cases
This arm will be compiled of prospectively recruited cases for confirmatory testing based on their suspected genotype per Michigan Genomics Initiative and patients who have been retrospectively identified as any patient who had clinical genotype testing and had a variant that was their clinician used to guide the chemotherapy treatment. Prospective patients will undergo confirmatory genetic testing by a CLIA lab and those results will be provided to the patients clinical team at that time.
Genetic: DPYD or UGT1A1 variants
any CLIA certified lab can be used for confirmatory testing after patients have been identified through Michigan Genomics Initiative (MGI)
Controls
This arm will be compiled of all retrospective patients where genetic information was not known prior to receiving treatment.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Comparison of grade 3 or higher AEs and SAEs
Time Frame: five months from treatment initiation
Compare rates of grade 3 or higher AEs and SAEs to fluoropyrimidine or irinotecan treatment between subjects with confirmed DPYD or UGT1A1 variants before chemotherapy treatment to retrospective matched controls without confirmatory PGx testing
five months from treatment initiation

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Comparison of PGx genotypes to MGI genotypes
Time Frame: five months from treatment initiation
clinical genotypes and MGI genotypes for participants will be considered concordant if they identify the same DPYD or UGT1A1 variant and discordant if they do not
five months from treatment initiation
Comparison of rates of dose reductions
Time Frame: five months from treatment initiation
A decrease in dose of standard of care treatment by >10% of the dose administered for the prior cycle
five months from treatment initiation
Comparison of treatment cycle delays
Time Frame: five months from treatment initiation
Any prolongation of the initiation of the following scheduled treatment cycle due to toxicity as documented by the patient's medical team
five months from treatment initiation
Comparison of treatment discontinuation
Time Frame: five months from treatment initiation
Any discontinuation due to clinician-documented toxicity
five months from treatment initiation
Clinician acceptance of supportive care pharmacogenetics
Time Frame: 6 months post first standard of care treatment
Evaluation of the amount of new prescriptions written with identified genetic interactions
6 months post first standard of care treatment
