Title:
Efficacy and safety of regorafenib plus biweekly TAS-102 for refractory metastatic colorectal cancer (REGTAS): A multicenter single-arm phase II trial.
Published date:
05/25/2023
Excerpt:
11 (68.7%) patients were enrolled within 18 months from diagnosis of mCRC. RAS and BRAF mutation were detected in 8 (50.0%) and 1 (6.3%) patients. Among 13 evaluable patients, 11 achieved SD and 2 had PD, with the DCR of 84.6% (95% CI: 54.6%-98.1%). The median PFS was 4.9 months (95% CI: 2.8-7.0)...Regorafenib plus biweekly TAS-102 exhibited promising benefits in terms of DCR and PFS, and could be a novel treatment option for patients with refractory mCRC. The adverse events were generally tolerable and manageable.

Title:
Regorafenib is suitable for advanced colorectal cancer patients who have previously received trifluridine/tipiracil plus bevacizumab
Published date:
02/10/2023
Excerpt:
Thirty-four advanced CRC patients who received regorafenib were analyzed....Twenty-two patients had left-sided tumors, 18 patients had RAS mutants, and 1 patient had a BRAF V600E mutation. The response rate was 0%, and the disease control rate was 31%. The median progression-free survival was 70 days (95% CI: 56-91), and the overall survival was 233 days (95% CI: 188-324)....Regorafenib after TFTD plus bevacizumab showed efficacy similar to that of the previous study, and no new adverse events were observed.
