Abstract 522P

Background

In the WJOG9216G randomized phase II study for patients with previously untreated mCRC, confirmed objective response rate (ORR) and progression-free survival (PFS) of FOLFOXIRI plus RAM were similar to those of FOLFIRI plus RAM (Kito et al. ESMO 2022). Previous studies of FOLFOXIRI plus bevacizumab suggested that age and UGT1A1 status might be associated with increased toxicity (Marmorino et al. Ann Oncol 2019, Oki et al. Clin Colorectal Cancer 2018). We conducted an exploratory post-hoc analysis to assess the impact of age and UGT1A1 status on the safety and efficacy.

Methods

Patients (aged ≤70 years with ECOG PS 0-1 or 71-75 years with PS 0, and wild-type [WT] UGT1A1 or single heterozygous [SH] UGT1A1 *28 or *6) were randomly assigned to arm A (FOLFIRI plus RAM) or arm B (8 cycles of FOLFOXIRI plus RAM followed by 5-FU/l-leucovorin plus RAM). ORR, PFS, overall survival (OS), and safety were assessed according to age and UGT1A1 status.

Results

Of the enrolled 122 patients (59/63 in arm A/B), 50/49 were

Conclusions

Compared with FOLFIRI plus RAM, FOLFOXIRI plus RAM did not improve ORR, PFS, and OS and might increase incidences of some adverse events, regardless of age and UGT1A1 status.
