Durvalumab and Tremelimumab With Platinum-based Chemotherapy in Intrahepatic Cholangiocarcinoma (ICC) (ICC)

An Open-label Window of Opportunity Trial to Evaluate the Activity of Durvalumab (MEDI4736) and Tremelimumab With Platinum-based Chemotherapy (Gemcitabine and Cisplatin) in Intrahepatic Cholangiocarcinoma (ICC)

This pilot trial will be used to assess the activity, safety and feasibility of doublet immunotherapy and platinum-based chemotherapy in resectable intrahepatic cholangiocarcinoma with high risk features. The hypothesis is that the combination of durvalumab/MEDI4736 and tremelimumab (doublet immunotherapy) with platinum-based chemotherapy (gemcitabine and cisplatin) will yield an objective of 52% and improve complete resection rates in intrahepatic cholangiocarcinoma. This will facilitate margin negative resection and ultimately reduce recurrence rates and improve survival. Carrying out this trial in the neoadjuvant setting potentially allows improved overall survival and also provides an opportunity for discovery of biomarkers that may predict response to therapy.

Study Overview

• Status: Terminated
• Conditions: Cholangiocarcinoma
• Intervention / Treatment: Drug: Novel combination of chemotherapy and immunotherapy

Detailed Description

All enrolled participants will receive the study intervention. Patients will receive up to 4 cycles of interventional agents prior to surgical resection. They will undergo imaging scans after the 2nd and 4th cycle (before surgery) of intervention agents. The short interval of scans (6 weeks) allows investigators to identify non responders. These patients may be encouraged to come off study and be treated based on the treating oncologist's choice. Since the investigational agents include 'standard of care' agents, a good argument can be made that these patients would not have benefitted from standard therapy only. Patients with at least stable disease after the 2nd treatment cycle will proceed with study interventions. However, patients with radiologic progression but who remain clinically stable may be allowed to continue treatment if the patient elects to, pending confirmation of progression and after a discussion between the investigator and sponsor-investigator.

Intervention / Treatment

Experimental: Novel combination of chemotherapy and immunotherapy; This study has one arm. All enrolled patients will receive a combination of a platinum based chemotherapy regimen (gemcitabine and cisplatin) and a combination of two immune check point inhibitors, anti- CTLA4 (Tremelimumab) and anti PDL-1 (durvalumab). Gemcitabine will be administered (gemzar) intravenously, 1000mg/m2 on Day 1 and Day 8 of a 21 day cycle for up to 4 cycles. Cisplatin (Platinol) will be administered intravenously, 25mg//m2 on Day 1 and Day 8 of a 21 day cycle for up to 4 cycles. Tremelimumab will be administered intravenously, 300mg flat dose, on Day 1 of cycle 1 only. Durvalumab will be administered intravenously 1500mg on Day 1 of a 21 day cycle for 4 cycles.

Drug: Novel combination of chemotherapy and immunotherapy; This is a study of the combination of platinum based chemotherapy (gemcitabine and cisplatin) and doublet immunotherapy (durvalumab and tremelimumab) in the preoperative setting for intrahepatic cholangiocarcinoma with high risk features. Gemcitabine and cisplatin are chemotherapy agents used in the management of locally advanced and metastatic cholangiocarcinoma. Durvalumab is a programmed cell death ligand 1 (PDL1) blocking antibody, that improves the immune response against cancer. Tremelimumab is an antibody that targets cytotoxic T cell lymphocyte-associated protein 4 (CTLA4) on regulatory T cells. It also improves the immune response against cancer cells; Other Names: Cisplatin (Platinol); Gemcitabine (Gemzar); Durvalumab (Imfimzi); Tremelimumab

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Objective Response Rate	We will obtain computerized tomography (CT) and/or magnetic resonance imaging (MRI) scans to assess the response to the intervention agents. We are interested in determining the percentage of patients who achieve a complete response or partial response (complete response plus partial response equals to objective response) when treated with intervention agents.	Assessments will occur after 2 cycles (6 weeks) of receiving treatment and after 4 cycles (12 weeks) of receiving treatment or before surgical resection, whichever happens first.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The Percentage of Participants That Complete Preoperative Therapy	We will assess the percentage of patients who receive all 4 cycles of preoperative therapy	Baseline through 16 weeks of treatment
Determine the Safety of the Combination of Intervention Agents by Assessing the Percentage of Patients Who Experience Dose Limiting Toxicities or Develop Adverse Reactions	Adverse reactions will be monitored and documented based on the National Cancer Institute's Common Terminology Criteria for Adverse Events version 5.0. The percentage of patients who experience different grades of adverse events will be assessed	Baseline through 16 weeks of treatment
Determine Changes in the Tumor mRNA Gene Expression Pattern, Phenotype of Circulating Cytotoxic T Cells, and Changes in Circulating Markers of Immunogenic Cell Death Following Treatment With Intervention Agents	We will compare the differences in the patterns between the responders and the non responders.	Baseline through 24 months
