Ipilimumab And Gemcitabine Hydrochloride In Treating Patients With Stage III-IV Or Recurrent Pancreatic Cancer That Cannot Be Removed By Surgery

Study Overview

Ipilimumab and Gemcitabine Hydrochloride in Treating Patients With Stage III-IV or Recurrent Pancreatic Cancer That Cannot Be Removed by Surgery

This phase I trial studies the side effects and best dose of ipilimumab when given together with gemcitabine hydrochloride in treating patients with stage III-IV or recurrent pancreatic cancer that cannot be removed by surgery. Monoclonal antibodies, such as ipilimumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or tumor-killing substances to them. Drugs used in chemotherapy, such as gemcitabine hydrochloride, work in different ways to kill tumor cells or stop them from growing. Giving monoclonal antibody therapy together with chemotherapy may kill more tumor cells.

OUTLINE: This is a dose-escalation study of ipilimumab. INDUCTION: Patients receive ipilimumab intravenously (IV) over 90 minutes in weeks 1, 4, 7, and 10, and gemcitabine hydrochloride IV over 30 minutes in weeks 1-7 and 9-11. MAINTENANCE: Beginning in week 22, patients receive ipilimumab IV over 90 minutes once every 12 weeks and gemcitabine hydrochloride IV over 30 minutes once weekly for 3 weeks. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Treatment modifications may apply according to response. After completion of study treatment, patients are followed up monthly for 6 months and then every 3 months.

Primary Outcome Measures	Measure Description	Time Frame
Number of Dose Limiting Toxicities (DLTs) Seen in Patients With Pancreas Adenocarcinoma Treated With Ipilimumab and Gemcitabine Combination in Order to Define the Maximum Tolerated Dose (MTD)	Dose limiting toxicity (DLT) will be monitored by calculating the Bayesian predictive probability of a DLT given the data to date. All toxicities will be summarized in a descriptive manner as to type, frequency, attribution and timing by dose level. Safety will be evaluated for all treated patients using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), Version 4.0 where grading is as follows: Mild (grade 1) Moderate (grade 2) Severe (grade 3) Life-threatening (grade 4) Fatal (grade 5) In general a DLT will be defined as any any of the following drug-related toxicities: Febrile neutropenia with grade 3/4 neutropenia Asymptomatic grade 4 neutropenia more than 7 days Grade 3 thrombocytopenia with grade 3-4 hemorrhage or grade 4 thrombocytopenia Non-hematologic toxicity grade 3 or 4 (with some protocol specified exceptions) DLTs will be used to determine the MTD for the expansion cohort of the study. *AST = Aspartate transamina	During the 12 weeks of Induction Therapy

Secondary Outcome Measures	Measure Description	Time Frame
Response Rate Using Immune-related Response Criteria (irRC) in Patients With Pancreas Adenocarcinoma Treated With Ipilimumab and Gemcitabine Combination	Response will be assessed using CT of MRI scans immune-related response criteria (irRC). The sum of all the products of diameters (SPD) at tumor assessment using the irRC for progressive disease incorporates the contribution of new measurable lesions. Each net percentage change in tumor burden per assessment using irRC accounts for the size and growth kinetics of both old and new lesions as they appear. irComplete Response (irCR)-Complete disappearance of all index lesions. irPartial Response (irPR)-Decrease of 50% or greater in the sum of products of the two largest perpendicular diameters of all index and all new measurable lesions (i.e., percentage change in tumor burden) irStable Disease (irSD)-does not meet criteria for irCR or ir PR, in the absence of progressive disease. irProgressive Disease (irPD)-At least 25% increase in the percentage change in tumor burden (i.e., taking sum of all the products of all the index lesions and any new lesions) when compared to SPD at nadir.	Every 12 weeks during treatment with a 12 week induction and then 28 day maintenance cycles. Range of cycles completed (including induction cycle) 0-10
Time to Progression Patients With Pancreas Adenocarcinoma Treated With Ipilimumab and Gemcitabine Combination Who Progress While on Treatment	Time to Progression will be defined as the time from treatment initiation until the first documentation of progression as calculated by irRC in patients who show progression. Progression will be defined as at least a 25% increase percentage change in tumor burden (i.e., taking the sum of all the products of all index lesions and any new lesions) when compared to sum of all the products of diameters (SPD) at nadir.	Every 12 weeks during treatment with a 12 week induction and then 28 day maintenance cycles. Range of cycles completed (including induction cycle) 0-10
Progression Free Survival (PFS) in Patients With Pancreas Adenocarcinoma Treated With Ipilimumab and Gemcitabine Combination	Median Progression Free Survival (mPFS) was estimated using a Kaplan-Meier curve with 0 censored patients. PFS is defined from the time of treatment initiation until the first documentation of progressive disease. Any patient without the event at the time of analysis will be censored from the last documented contact.	Every 12 weeks during treatment with a 12 week induction and then 28 day maintenance cycles. Range of cycles completed (including induction cycle) 0-10
Overall Survival (OS) in Patients With Pancreas Adenocarcinoma Treated With Ipilimumab and Gemcitabine Combination	Overall Survival (OS) was estimated using a kaplan-meier curve with 0 patients censored. OS is defined from the time of treatment initiation until the time of death from any cause. Any patient without the event at the time of analysis will be censored from the last documented contact.	Every 12 weeks during treatment with a 12 week induction and then 28 day maintenance cycles. Range of cycles completed (including induction cycle) 0-10
Recovery of Tumor Immune Surveillance: T-cell Response to Defined Pancreatic Cancer Tumor Antigens	Optional blood draws to analyze the inflammatory T cell function before, during and after treatment.	Prior to ipilimumab infusion at weeks 1, 4, 7, and 10, and then every 12 weeks starting at week 13 where range of cycles including induction cycle was 0-10 (Induction cycle = 12 weeks, maintenance cycle = 28 days)
