 (submitted: July 12, 2012)
Predefined fluoropyrimidine-related (index) toxicity [ Time Frame: After 6 weeks of fluoropyrimidine-based treatment ]
Index toxicity is defined as follows:
  • All adverse events CTC grades ≥3, including myelosuppression but excluding nausea and vomiting (that is often due to concurrent platinum drug treatment)
  • Fluoropyrimidine-related toxicity CTC grade ≥2, including mucositis, dehydration, hand-foot syndrome
  • Diarrhea CTC grade ≥2 lasting for >/=5 days or an increase of 2 CTC grades in case of preexisting diarrhea. Diarrhea should not be evaluated in patients with a colostomy

Current Secondary Outcome Measures  ICMJE
 (submitted: July 12, 2012)
  • Area-under-the plasma-concentration time curve of 5-fluorouracil [ Time Frame: at 8 weeks ]
    AUC of 5FU as derived from 5FU steady-state plasma concentrations, taken 2 hours before the planned end of the continuous drug infusion. 5FU target AUC is defined as within the range of 20-30 mg•h/L
  • Endogenous dihydrouracil/uracil ratio in plasma [ Time Frame: at start of each treatment cycle ]
    Endogenous UH2 to U ratio as analysed at the time of PK sampling of 5FU or Cp, and repeated for each treatment cycle.
  • Objective treatment response (best response) according to RECIST v.1.1 [ Time Frame: end of first-line treatment ]
    Objective treatment response according to the RECIST criteria v1.1 is assessed in all patients
  • Progression-free survival [ Time Frame: time of disease progression or death ]
    Defined as the time interval between start of study treatment and disease progression or death, whatever comes first.

Descriptive Information
Brief Title  ICMJE Pharmacology-driven Dosing of Fluoropyrimidines in Cancer Patients
Official Title  ICMJE Pharmacogenetics and Therapeutic Drug Monitoring for the Optimization of Fluoropyrimidine Treatment in Patients With Advanced Colorectal Cancer
Brief Summary The fluoropyrimidines 5-fluorouracil (5FU) and capecitabine (Cp) are among the most commonly used anticancer drugs. Still, there is much controversy about the correct dosing, and the fact that a minority of patients experience severe, sometimes even lethal toxicity following treatment. One important factor predisposing patients to severe toxicity is deficiency in the 5FU-catabolic enzyme dihydropyrimidine dehydrogenase (DPD). Our group identified 4 DPD risk alleles in over 300 Swiss cancer patients, that resulted in a 8-times increased risk of experiencing severe toxicity from 5FU or Cp. In patients receiving 5FU as a continuous infusion, there are accumulating data that keeping the AUC of 5FU between 20-30 mg*h/L is beneficial in terms of treatment toxicity and activity. In this study, patients carrying at least 1/4 DPD risk alleles will receive a 50% dose reduction of either 5FU or Cp, with the potential of later dose increases in the abscence of severe toxicity. Additionally, patients receiving i.v. 5FU will undergo therapeutic drug monitoring at the end of the 2-day continuous infusion, with subsequent dose adaptations to target a 5FU AUC of 20-30 mg*h/L. The primary study objective is to reduce the incidence of severe treatment-related toxicity from 13% (in historical controls) to 5% in study patients.

  • Other: 5FU and capecitabine (Xeloda®) dosing based on DPYD genotype
    Multiplex amplification of each sample is performed in an individual well of a 24-well plate using a Mastercycler platform. Template and Platinum Taq Polymerase (Life Technologies, Carlsbad, California) are added to an analyte-specific amplification mix (AutoGenomics Inc., Carlsbad, California). After amplification, the plate is transferred into the Infinity analyzer (AutoGenomics Inc.), followed by primer extension and hybridization of detection primers to individual oligonucleotides arrayed on the Bio-FilmChip. After hybridization, the BioFilmChips are washed and scanned in the Infiniti optics module. The Autogenomics DPYD assay is used to detect the presence of the four risk alleles (IVS14+G>A, c.1679T>G, HapB3/c.1129-5923C>G and c.2846A>T).
  • Other: Therapeutic drug monitoring of 5FU
    Repeated PK plasma sampling is done in all patients receiving 5FU. Blood is taken from venipuncture into one 5 ml heparin tube and into one 3 ml EDTA tube for the analysis of 5FU steady-state plasma concentrations in every (2-weekly) treatment cycle. Special attention has to be paid not to take PK blood from the site of drug infusion. For 5FU, PK sampling is done two hours before the calculated end of the 5FU pump on day 3 of every treatment cycle. The quantitative 5FU exposure expressed as the area-under-the concentration-time curve in mg•h/L is calculated from the measured steady-state plasma concentrations of 5FU and the duration of 5FU infusion. In all patients, 5FU doses for the second and subsequent administrations are adjusted to target a 5FU AUC between 20 and 30 mg•h/L
