Randomized phase II study of oxaliplatin reintroduction and the biweekly XELOX in previously treated patients with metastatic colorectal cancer (ORION study)

Phase 2
Conditions
Colorectal Cancer
Registration Number
JPRN-UMIN000004122
Lead Sponsor
PO Epidemiological and Clinical Research Information Network (ECRIN)
Brief Summary

RESULTS: A total of 46 patients were enrolled in the trial-22 patients were randomly assigned to the Q3W group and 23 to the Q2W group. The median TTF was 3.4 months in both groups (hazard ratio [HR] 1.053; p = 0.880). The median PFS and OS were 3.3 and 9.2 months in the Q2W group and 4.3 and 12.1 months in the Q3W group, respectively (HR 1.15; p = 0.153 and 0.672; p = 0.836). The most common grade 3-4 AEs in the Q3W and Q2W groups were fatigue (27.3 vs 21.7), neuropathy (9.1 vs 0 %) and diarrhea (9.1 vs 0 %), respectively.
