- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE

Eligibility Criteria:
Inclusion Criteria:~* Histological confirmation of advanced biliary tract cancers including cancers originating in the gallbladder who have received at least one line of systemic anticancer therapy~  * Note: Patients who have either progressed on or are intolerant to the prior therapy can be included in this study~* Measurable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST) criteria~  * NOTE: Tumor lesions in a previously irradiated area are not considered measurable disease.

Study Arms:
- Treatment (trifluridine and tipiracil, irinotecan) (Type: EXPERIMENTAL): Patients receive trifluridine and tipiracil hydrochloride PO BID on days 1-5 and irinotecan hydrochloride IV over 90 minutes on day 1.
