Liposomal Irinotecan, Fluorouracil And Leucovorin In Treating Patients With Refractory Advanced High Grade Neuroendocrine Cancer Of Gastrointestinal, Unknown, Or Pancreatic Origin

Study Overview

Liposomal Irinotecan, Fluorouracil and Leucovorin in Treating Patients With Refractory Advanced High Grade Neuroendocrine Cancer of Gastrointestinal, Unknown, or Pancreatic Origin

This phase II trial studies how well liposomal irinotecan, leucovorin, and fluorouracil work in treating patients with high grade neuroendocrine cancer of gastrointestinal, unknown, or pancreatic origin that does not respond to treatment and has spread to other places in the body. Lliposomal irinotecan may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as fluorouracil and leucovorin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving liposomal irinotecan, leucovorin and fluorouracil may work better in treating patients with neuroendocrine cancer.

PRIMARY OBJECTIVES: I. To determine the objective response rate liposomal irinotecan (nanoliposomal irinotecan [Nal-IRI]) + fluorouracil (5FU) and leucovorin in patients with refractory advanced high grade neuroendocrine cancer of gastrointestinal (GI), unknown or pancreatic origin. SECONDARY OBJECTIVES: I. To determine overall survival, progression-free survival, time to treatment failure, safety, clinical response and, quality of life (QOL) changes resulting from the combination treatment of nanoliposomal irinotecan (Nal-IRI) + fluorouracil (5FU) and leucovorin. EXPLORATORY OBJECTIVES: I. Genetic profiling for mutations will be conducted on all pre-study tumor samples and compared to changes in immune response. OUTLINE: Patients receive liposomal irinotecan intravenously (IV) over 90 minutes, leucovorin IV over 30 minutes, and fluorouracil IV over 46 hours on days 1 and 15. Courses repeat every 28 days for in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for 30 days, then every 2 months thereafter.

Primary Outcome Measures	Measure Description	Time Frame
Objective Response Rate (ORR) as Assessed by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1	Will be summarized using frequencies and relative frequencies; with the ORR (= CR+PR / N) estimated using an 80% confidence interval obtained using Jeffrey's prior method. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions.	Within 6 months of treatment initiation

Secondary Outcome Measures	Measure Description	Time Frame
Overall Survival	Will be summarized using standard Kaplan-Meier methods; where estimates of the median time will be obtained with 95% confidence intervals.	From first dosing of study treatment combination to time of death or imitation of a new therapy, assessed up to 3 years
Progression-free Survival Assessed by RECIST 1.1	Will be summarized using standard Kaplan-Meier methods; where estimates of the median time will be obtained with 95% confidence intervals. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.	From first dosing of study treatment combination to disease progression, assessed up to 3 years
Time-to Treatment Failure	Will be summarized using standard Kaplan-Meier methods; where estimates of the median time will be obtained with 90% confidence intervals.	From enrollment to discontinuation of treatment, assessed up to 3 years
Proportion of Patients Achieving an Objective Response Based on Prior Response to Platinum Etoposide	The objective response rate (ORR) is as described in the primary analysis. Here it is reported in the subset of patients that received prior platinum etoposide therapy.	Up to 3 years
Clinical Benefit Response	Defined as either achievement of pronounced and sustained (>=4 weeks contiguous) improvement in pain intensity, analgesic consumption, or performance status, or a combination of these, without any worsening in any of the other factors, or stability in pain intensity, analgesic consumption, and performance status with pronounced and sustained (>= 4 weeks contiguous) weight gain. Will be treated as binary data and summarized using frequencies and relative frequencies. The clinical benefit response rate will be estimated using a 90% confidence interval obtained by Jeffrey?s prior method.	Up to 3 years
Quality of Life (QOL) as Assessed by European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30)	Will be treated as quantitative data and summarized by time-point using the mean and standard deviation. The QOL scores at each follow-up time may be compared with base-line levels using the paired t-test or sign test. The overall QoL rating ranges from 0 (poor) to 10 (good).	From treatment initiation until treatment completion/progression (up to 3 years).
Incidence of Grade 3+ Treatment Related Adverse Events (TRAE)	Toxicities and adverse events will be summarized by attribution and grade using frequencies and relative frequencies. High grade (3+) toxicity and adverse event rates may be estimated using 90% confidence intervals obtained by Jeffrey's prior method. Data Safety Monitoring Board (DSMB) monitoring will also occur periodically to ensure safety of study subjects.	Up to 3 years
