What to expect

No one can promise a trial will help you personally — that is what the research is trying to find out.

Show the study's own words
  • "Dosing of FP, specifically 5-FU, has been a challenge since this drug was first synthesized in 1957 by Charles Heidelberger1. 5FU had been given on numerous schedules and doses, including weekly 24 hr infusion, 48-hour infusion every two weeks, and daily five-times-a-day infusion with leucovorin (Mayo Regimen) and weekly bolus with leucovorin infusion (Roswell, Park Regimen)."
Compensation
Not stated
  • Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
  • Participants are monitored closely by the research team throughout the study.
  • Some participants may receive access to an investigational treatment, which is still being studied.
  • Your participation helps researchers learn whether this approach could help future patients.

About this study

To prospectively evaluate the efficacy and safety of DPYD-guided dosing strategies in a real-world clinical setting, specifically by comparing the incidence of severe (Grade 3 and 4) fluoropyrimidine-related toxicities of heterozygous DPYD variant patients assigned to DPYD-guided reduced dosing versus patients with standard dosing in the control arm.

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Eligibility

Official eligibility criteria

Inclusion Criteria: * Diagnosis of cancer in either the adjuvant or metastatic setting requiring initial therapy with 5-FU or Capecitabine. * DPYD testing performed by a CLIA-certified laboratory (i.e., Guardant 360 or Caris blood testing for genomic profiling, DPYD testing by the Mayo Clinic or other certified laboratory) with results available before starting chemotherapy. * DPYD testing results falling into one of the following cohorts for first-line therapy with a fluoropyridine: * Study Cohort: Patients with one DPYD variant in one gene (heterozygotes). * Control Arm: Patients with normal or wild-type DPYD genes, for comparison, will be treated at the usual 100% dose. --FOLFOX regimen (N=50) * ECOG Performance Status 0-2. * Measurable disease or non-measurable disease allowed, including adjuvant 5-FU-based regimens. Exclusion Criteria: * Patients for whom 5-FU or Capecitabine therapy is contraindicated or not deemed appropriate in the judgment of the treating physician. * Patients with two DPYD variants (homozygous deletions or non-functional genetic variants, or double heterozygotes with two different abnormalities) should not receive 5-FU or Capecitabine and are therefore excluded from the study. * Pregnant Women and Children
