Study Details

Study Description

Brief Summary

The goal of this clinical trial is to test feasibility and safety of the combination of tremelimumab and durvalumab plus gemcitabine and cisplatin as a neoadjuvant treatment bridge patients to a curative resection in treatment naïve borderline resectable, or resectable with high risk for recurrence intrahepatic cholangiocarcinoma patients. The main question[s] it aims to answer are:

  • What is the rate of conversion of unresectable tumor to resectable cancer?

  • What are the side effects of this treatment combination?

Participants will undergo an initial tumor biopsy, imaging and laboratory studies prior to starting treatment with durvalumab, tremelimumab, gemcitabine and cisplatin. Participants will continue for 4 cycles and if the tumor is found to be resectable then they will undergo surgical resection. If the tumor is unresectable (can't be surgically removed) after 4 cycles, then participants will receive 4 more cycles and repeated imaging. If the tumor remains unresectable then the participant will be treated with capecitabine for up to 8 cycles and durvalumab for up to 12 months.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Durvalumab and Trememlimumab plus gemcitabine/cisplatin

Durvalumab and tremelimumab plus gemcitabine/cisplatin combination therapy. If the tumor is evaluated to be resectable after Cycle 4 (C4), then the patient may proceed with surgical tumor resection. If the tumor is deemed unresectable after C4, then the patient will proceed with Cycle 5-8 followed by reevaluation for surgical resection.

Drug: Durvalumab
Durvalumab 1500 mg via intravenous (IV) infusion every 3 weeks for up to 8 cycles

Drug: Tremelimumab
A single dose of tremelimumab at 300mg IV is given on C1.

Drug: Gemcitabine
Gemcitabine is dosed at 1000 mg/m2 IV on day (D)1 and D8 of each cycle.

Drug: Cisplatin
Cisplatin is dosed at 25mg/m2 on D1 and D8 of each cycle.

Procedure: Surgical Resection
If the tumor is evaluated to be resectable (as defined as successfully treated stage II (tumor shrink away from vessels), stage IIIA (tumor shrink away from visceral peritoneum), stage IIIB (N1 disease no longer pathologically enlarged) after C4 or C8, then the patient may proceed with surgical tumor resection.

Outcome Measures

Primary Outcome Measures

  1. Rate of Conversion from unresectable to resectable [8 Cycles, 21 day cycles]

    Rate of conversion of unresectable tumor to resectable cancer after neoadjuvant durvalumab + tremelimumab + gemcitabine + cisplatin after 4 or 8 cycles. Surgical evaluation will be done in joint by institutional radiology and hepatobiliary surgery using clinical data (CT/MRI imaging, patient performance status, labs, etc.) If among the evaluable 24 patients, 9 or more (45%) patients undergo such conversion, the investigational treatment will be considered as promising/feasible. The resectable rate will be estimated with its 95% exact confidence interval.

  2. Incidence of related treatment emergent adverse events [36 months]

    Number of participants with related treatment emergent adverse events

Secondary Outcome Measures

  1. Objective Response Rate [36 months]

    ORR will be estimated with its 95% exact confidence interval based on RECIST v1.1

  2. Pathological complete response (pCR) [36 months]

  3. Overall survival (OS) [36 months]

    Kaplan-Meier method is used to represent secondary outcome OS.

  4. Progression-free survival (PFS) [36 months]

    Kaplan-Meier method is used to represent secondary outcome of PFS

  5. Rate of R0 resection [8 Cycles, 21 day cycles]

    R0 resection rate will be estimated with its 95% exact confidence interval

  6. Relapse free survival (RFS) [36 months]

    Kaplan-Meier method will be used to analyze RFS

  7. Patient Reported outcomes (PRO) decline [8 Cycles, 21 day cycles]

    As measured by qualify of life changes per EORTC QLQ-BIL-20 questionnaires

  8. Event Free Survival (EFS) [36 months]
