A phase 2 refractory CRC trial with the TAS-102/bevacizumab combo.
The first trial had a median follow up of 10 months with 47 patients in the TAS-102 arm and 46 patients in the TAS-102/bevacizumab arm. In the combo mPFS was 4.6 months and mOS was 9.4 months.

From Aug 24, 2017, to Oct 31, 2018, 93 patients were enrolled and randomly assigned to TAS-102 (n=47) or TAS-102 plus bevacizumab (n=46). The clinical cut-off date was Feb 15, 2019, after a median follow-up of 10·0 months (IQR 6·8-14·0). The most frequent grade 3 or worse adverse event was neutropenia (18 [38%] of 47 in the TAS-102 monotherapy group vs 31 [67%] of 46 in the TAS-102 plus bevacizumab group). Serious adverse events were observed in 21 (45%) patients in the TAS-102 group and 19 (41%) in the TAS-102 plus bevacizumab group. No deaths were deemed treatment related.
Median progression-free survival was 2∙6 months
(95% CI 1∙6–3∙5) in patients receiving TAS-102
monotherapy and 4∙6 months (3∙5–6∙5) in patients
receiving TAS-102 plus bevacizumab (HR 0∙45, 95% CI
0∙29–0∙72; p=0∙0010
Median overall survival was 6∙7 months (95% CI
4∙9–7∙6) in patients receiving TAS-102 monotherapy and
9∙4 months (7∙6–10∙7) in patients receiving TAS-102 plus
bevacizumab (HR 0∙55, 95% CI 0∙32–0∙94; p=0∙028
Disease control (complete or partial response or stable
disease according to RECIST 1.1) was reported in 24 (51%)
patients in the TAS-102 monotherapy group and 31 (67%)
patients in the TAS-102 plus bevacizumab group
(p=0·14). One patient in the TAS-102 plus bevacizumab
group had a partial response. No patient in the TAS-102
group had a partial response.
