Trial Outcomes & Findings for Trifluridine/Tipiracil and Irinotecan for the Treatment of Advanced Refractory Biliary Tract Cancer (NCT NCT04072445)

NCT ID: NCT04072445

Last Updated: 2023-08-09

Results Overview

Will be defined as the proportion of evaluable patients who are progression-free (stable disease, partial response, complete response) at 16 weeks and assessed using Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1. Confidence intervals for the true success proportion will be calculated according to the approach of Clopper and Pearson.

OTHER_PRE_SPECIFIED outcome

Timeframe: Up to 20 months

Will determine if drug response from a parallel ex vivo trial using patient-derived tumor organoid correlates with clinical response to trifluridine and tipiracil hydrochloride (trifluridine/tipiracil) plus irinotecan hydrochloride (irinotecan).

Outcome data not reported

OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline

Will evaluate the role of TK1 in predicting the clinical benefit of trifluridine/tipiracil plus irinotecan and discover potential mechanisms of resistance using patient-derived tumor organoid and pre-treatment biopsy specimen.
