Testing Pump Chemotherapy in Addition to Standard of Care Chemotherapy Versus Standard of Care Chemotherapy Alone for Patients With Unresectable Colorectal Liver Metastases: The PUMP Trial
Study Details
Study Description
Brief Summary
This phase III trial compares hepatic arterial infusion (HAI) (pump chemotherapy) in addition to standard of care chemotherapy versus standard of care chemotherapy alone in treating patients with colorectal cancer that has spread to the liver (liver metastases) and cannot be removed by surgery (unresectable). HAI uses a catheter to carry a tumor-killing chemotherapy drug called floxuridine directly into the liver. HAI is already approved by the Food and Drug Administration (FDA) for use in metastatic colorectal cancer to the liver, but it is only available at a small number of hospitals, and most of the time it is not used until standard chemotherapy stops working. Standard chemotherapy drugs 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. Adding HAI to standard chemotherapy may be effective in shrinking or stabilizing unresectable colorectal liver metastases.

Detailed Description
PRIMARY OBJECTIVE:
- To determine if patients with persistently unresectable colorectal liver metastases (CRLM) after treatment with first-line chemotherapy have improved overall survival (OS) with hepatic arterial infusion (HAI) and systemic chemotherapy versus systemic chemotherapy alone.
SECONDARY OBJECTIVES:
- To determine whether there is a direct association between hepatic progression free survival (hPFS) and overall survival (OS) when patients are treated with HAI combined with systemic chemotherapy for unresectable CRLM.
II To determine the impact on progression free survival (overall, hepatic and extrahepatic) for patients with unresectable CRLM treated with HAI in combination with systemic chemotherapy.
-
To determine objective response rate (ORR) in the liver, defined as the proportion of patients achieving complete or partial response by Response Evaluation Criteria is Solid Tumors (RECIST) 1.1.
-
To determine the rate of conversion to resectable disease, defined as the proportion of patients who successfully convert from unresectable to resectable status and undergo R0/R1 resection/ablation.
-
To determine the rate in which patients are intended to be treated with HAI but are deemed ineligible at the time of planned pump insertion due to detection of occult extrahepatic disease or unsuitable arterial anatomy (Intra-Operative Ineligibility, IOI).
-
To determine the extent to which patient and disease-specific factors correlate with short- and long-term risk of HAI-specific complications.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM A: Patients undergo surgery to place the HAI pump, followed by single photon emission computed tomography/computed tomography (SPECT/CT) on study. Patients then receive floxuridine via the HAI pump on study. Patients also receive one of the following standard chemotherapy regimens per the treating physician: FOLFOX (fluorouracil intravenously [IV], oxaliplatin IV, and leucovorin IV), FOLFIRI (fluorouracil IV, irinotecan IV, and leucovorin IV), or OX/IRI (oxaliplatin IV and irinotecan IV) with or without cetuximab IV and/or panitumumab IV on study. Patients also undergo CT scans throughout the trial.
ARM B: Patients receive one of the following standard chemotherapy regimens per the treating physician: FOLFOXIRI (fluorouracil IV, oxaliplatin IV, irinotecan IV, and leucovorin IV), FOLFOX, FOLFIRI, or OX/IRI with or without cetuximab IV, panitumumab IV, and/or bevacizumab IV on study. Patients also undergo CT scans throughout the trial.

Outcome Measures
Primary Outcome Measures
- Overall survival (OS) [From randomization to death from any cause, assessed up to 5 years]
Patients still living will be censored at the date last known alive. OS will be evaluated using the Kaplan-Meier method, and arms will be compared via a stratified log rank test.
Secondary Outcome Measures
- Progression free survival (PFS) [From randomization to first observed disease progression at any site, or death from any cause, assessed up to 5 years]
Patients still living without disease progression will be censored at the date of last disease assessment. Disease progression will be based on findings from surveillance cross-sectional imaging of the chest/abdomen/pelvis every 3 months after randomization, defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. Will be analyzed similarly to OS, but with and without stratification for sensitivity.
- Hepatic PFS [From randomization to first observed disease progression in the liver, or death from any cause, assessed up to 5 years]
Patients still living without hepatic disease progression will be censored at the date of last disease assessment. Hepatic disease progression will be based on findings from surveillance cross-sectional imaging of the chest/abdomen/pelvis every 3 months after randomization, defined by RECIST 1.1.
- Extrahepatic-PFS [From randomization to first observed disease progression outside of the liver, or death from any cause, assessed up to 5 years]
Patients still living without extrahepatic disease progression will be censored at the date of last disease assessment. Extrahepatic disease progression will be based on findings from surveillance cross-sectional imaging of the chest/abdomen/pelvis every 3 months after randomization, defined by RECIST 1.1.
- Objective response rate [Up to 5 years]
Will assess hepatic disease burden specifically. Defined as the proportion of patients achieving complete or partial response by RECIST 1.1. Response will be based on surveillance cross-sectional imaging of the chest/abdomen/pelvis every 3 months (+/- 2 weeks) after initiation of treatment (Arm A = surgery, Arm B = cycle 1, day 1 of chemotherapy). Arms will be compared via a Pearson chi-square test. All rates will be reported with exact binomial 95% confidence intervals.
- Rate of conversion to resectable disease [Up to 5 years]
Defined as the proportion of patients who successfully convert from unresectable to resectable status and undergo R0/R1 resection/ablation. All rates will be reported with exact binomial 95% confidence intervals.
- Intra-operative ineligibility rate [Up to 5 years]
Defined as the proportion of patients intended to receive hepatic arterial infusion that do not undergo pump implantation due to intraoperative detection of occult extrahepatic disease or unsuitable hepatic arterial anatomy. All rates will be reported with exact binomial 95% confidence intervals.
- Incidence of adverse events [Up to 5 years]
Defined according to the Common Terminology Criteria for Adverse Events.
