OnDose™—The Data You Need to Optimize Dosing

The OnDose Results Report provides you with important information about your patient's infusional 5-FU dosing and area under the curve (AUC) history. The report shows the physician-supplied dose (mg/m2) for each treatment date and the calculated 5-FU exposure (expressed as AUC). This information can be used to optimize infusional 5-FU chemotherapy within a target AUC range (20-24 mg•h/L) for future cycles (ie, increase, decrease, or maintain).



  • Provides individualized data to guide dosing into an optimal range of 20-24 mg•h/L

  • Designed to provide you with an accurate and timely measurement of infusional 5-FU exposure

  • Test results are used to help optimize an individualized dose for the next cycle of infusional 5-FU chemotherapy
    • For the following cycles, repeat the test each time until desired AUC range is reached and maintained for at least 3 cycles
    • After maintaining target AUC levels for at least 3 cycles, monitor every third cycle

  • A recent publication by Gamelin et al showed infusional 5-FU dose adjustments as a function of infusional 5-FU exposure recorded during the previous cycle of treatment1

  • This protocol can be used to optimize infusional 5-FU chemotherapy for future cycles (ie, increase, decrease, or maintain)1

NOTE: Any dose adjustment should reflect your professional clinical experience and medical knowledge of the patient.
