Abstract 3024

Background

TAS-102 demonstrated significant improvement in overall survival (OS) over placebo in patients (pts) with metastatic colorectal cancer (mCRC). Nintedanib is a triple angiokinase inhibitor of VEGFR (1, 2, 3), PDGFR (a, β), and FGFR (1, 2, 3). In preclinical models, the combination of TAS-102 plus nintedanib demonstrated enhanced activity against CRC compared with either drug alone. This study was conducted to determine the recommended phase II dose (RP2D) and evaluate the efficacy and safety in pts with mCRC refractory to standard therapies. RP2D was determined nintedanib 200mg BID every day adding to standard-dose of TAS-102 in the phase I part (Nishina T, et al. ESMO 2016). We present here on the efficacy and safety data from the ongoing study.

Methods

The key eligibility criteria were pts with mCRC refractory or intolerant to fluoropyrimidine, irinotecan, oxaliplatin, anti-angiogenesis inhibitor and anti-EGFR antibody (if wild-type RAS) and without prior regorafenib. Primary endpoint was investigator-assessed progression-free survival (PFS) rate at 16 weeks in pts treated with RP2D. Using a single stage binomial design, this study required 52 pts, with the PFS rate at 16 weeks of 40% deemed promising and 25% unacceptable (alpha=0.1; beta=0.2).

Results

From August 2015 to August 2016, 55 pts were enrolled. Among them, 52 pts received the RP2D as full analysis set. The PFS rate at 16 weeks was 38.5% (80% confidence interval: 29.3–48.3%). Four pts (7.7%) achieved a partial response, median PFS and disease control rate were 3.7 months and 69.2%, respectively. Median OS was 9.2 months. The median number of treatment cycles was 4 (range 1 - 14). The most common grade 3 or worse treatment-associated adverse events were neutropenia (59.6%), anemia (17.3%), thrombocytopenia (11.5%) and increased liver enzymes (AST: 9.6%, ALT: 7.7%; asymptomatic reversible elevation without any bilirubin elevation). Febrile neutropenia occurred in two (3.8%) pts. There was no treatment-related death.

Conclusions

Standard-dose of TAS-102 with nintedanib 200 mg BID showed promising antitumor activity with acceptable toxicity for mCRC pts.
