TAS-102, Irinotecan, and Bevacizumab in Pre-treated Metastatic Colorectal Cancer (TABAsCO), A Phase II Clinical Trial. ClinicalTrials.gov NCT04109924

Project description:Background: The efficacy of FOLFIRI plus an antiangiogenesis biologic agent as 2nd line therapy for metastatic colorectal adenocarcinoma is limited. TAS-102 is a novel oral antimetabolite with a distinct mechanism of action from fluoropyrimidines. We evaluated the antitumor efficacy of TAS-102, irinotecan and bevacizumab in patients with pre-treated, advanced colorectal adenocarcinoma in a multicenter, phase II, single-arm study. Methods: Patients with advanced colorectal adenocarcinoma who had progressed after oxaliplatin and fluoropyrimidine and were eligible for treatment with bevacizumab were treated with irinotecan, bevacizumab, and TAS-102 in 28-day cycles. The primary endpoint was progression-free survival (PFS). Results: We enrolled 35 evaluable patients. The study was positive. The median PFS was 7.9 (90% CI 6.2-11.8) months (vs. 6 months in historical control, p=0.018). The median overall survival was 16.5 (90% CI 9.8-17.5) months. Sixty-seven percent of patients experienced grade 3 or higher treatment-related adverse events. The most common toxicities were hematological (neutropenia) and gastrointestinal (diarrhea, nausea, and vomiting). Conclusions: Irinotecan, TAS-102 and bevacizumab is an active 2nd line therapy for patients with metastatic colorectal adenocarcinoma. Neutropenia is common and can affect dose density/intensity mandating use of G-CSF. A randomized study versus standard of care therapy is warranted.

A Comparison of Bevacizumab Plus TAS-102 and TAS-102 Monotherapy for Metastatic Colorectal Cancer: A Systematic Review and Meta-Analysis.

Project description:BackgroundsAs a new oral chemotherapy drug, TAS-102 is currently recommended as the third-line treatment for metastatic colorectal cancer (mCRC). Recently, studies have reported the efficacy of TAS-102 combined with bevacizumab in colon cancer patients after standard treatment fails. Here, we evaluated the efficacy and safety of TAS-102 combined with bevacizumab versus TAS-102 as a single agent by a systematic review and a meta-analysis.MethodsPubMed, Web of Science and Cochrane libraries were searched. Studies involving bevacizumab combined with TAS-102 in mCRC were included. Study characteristics (author, year of publication, country et al.), efficacy (disease control rate(DCR), progression-free survival(PFS), overall survival(OS)) and adverse effects were extract from studies. Forest plots were created based on Cox model analysis.ResultsAfter screening 550 studies, a total of 3 studies were included, which compared the safety and effectiveness of TAS-102 with or without bevacizumab. Analysis based on Cox regression showed that the combined treatment group had advantages in 6-month (OR= 2.93, 95% CI: 1.72 to 5.00, P<0.0001), 12-month(OR= 2.18, 95% CI: 1.24 to 3.81, P=0.006), and 18-month (OR=3.08, 95% CI: 1.34 to 7.12, P=0.008) OS. The combined treatment group demonstrated superiority in 6-month PFS rates (OR= 2.50, 95% CI: 1.18 to 5.31, P=0.02). The incidence of thrombocytopenia in the dual-drug treatment group was higher (OR= 1.96, 95% CI: 1.14 to 3.36 P=0.01). The proportion of serious adverse events were similar in tow groups (OR= 1.01, 95% CI: 0.76 to 1.34 P=0.93).ConclusionBevacizumab combined with TAS-102 could improve the prognosis of patients with mCRC who have failed standard treatment. In terms of side effects, the addition of bevacizumab did not increase serious adverse reactions, but the occurrence of thrombocytopenia was worth noting.

TAS-102 and Oxaliplatin for the Treatment of Refractory Stage IV Colon Cancer

Project description:This phase II trial studies how well TAS-102 and oxaliplatin work in treating patients with stage IV colon cancer. Drugs used in chemotherapy, such as TAS-102 and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.
