Panitumumab DDI Irinotecan
A Phase I, Open-label Study to Determine the Effect of Panitumumab on the Pharmacokinetics of Irinotecan in Subjects With Unresectable Metastatic Colorectal Cancer

The primary objective of this study is to determine if panitumumab affects the pharmacokinetic (PK) profile of irinotecan. The hypothesis is panitumumab does not affect the PK of irinotecan. This will be concluded if the 90% confidence intervals of the ratio of geometric means for the Cmax and AUC for irinotecan with and without concomitant panitumumab administration fall inside the interval of 70-143%.

Phase 1
Endpoint Classification: Pharmacokinetics Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Metastatic Colorectal Cancer
  • Drug: Panitumumab
    The first infusion of panitumumab will occur on Cycle 1 Day 4. On Cycle 2 Day 1, panitumumab will be administered on the same day as irinotecan and every 2 weeks thereafter.
