Metastatic colorectal cancer
Trial or other data
Dec 21Previously in Mar 14, Taiho completed the PIII SOFT trial, which investigated non-inferiority of S 1 + oxaliplatin + bevacizumab compared with standard regimen fluorouracil + folinic acid + oxaliplatin (mFOLFOX6) + bevacizumab in patients with metastatic colorectal cancer (JapicCTI090699). The primary end-point was to assess progression free survival .
Mar 18PIII SALTO trial completes (NCT01918852). It met the primary end point with a lower incidence of hand-foot syndrome (HFS) in patients who were administered S 1. Nordic Pharma and Dutch Colorectal Cancer Group completed the trial, that evaluated the safety of S 1 versus capecitabine in the first-line treatment of patients with metastatic colorectal cancer. The randomised, parallel-assignment, open-label study was initiated in December 2013, and enrolled 161 patients in the Netherlands [3,4].
Jun 12PIII TRICOLORE trial to evaluate the efficacy and tolerability of S 1 in combination with irinotecan and bevacizumab, compared with oxaliplatin-based chemotherapy (mFOLFOX6), as first-line therapy in patients with colorectal cancer starts (UMIN000007834). The randomised, open-label trial will enrol 487 patients in Japan .
