Cisplatin, Irinotecan and Bevacizumab (PCA) Versus Docetaxel, Cisplatin, Irinotecan and Bevacizumab (TPCA) in Metastatic Esophageal and Gastric Cancer

A Randomized, Multicenter, Phase II Trial of Cisplatin, Irinotecan and Bevacizumab (PCA) vs. Docetaxel, Cisplatin, Irinotecan and Bevacizumab (TPCA) in Metastatic Esophageal and Gastric Cancer

There is no clear standard of care for metastatic stomach or esophageal cancer in the United States. The purpose of this research study is to determine the differences between two regimens of chemotherapy; Arm A: PCA (Cisplatin, Irinotecan and Bevacizumab) and Arm B: TPCA (Docetaxel, Cisplatin, Irinotecan and Bevacizumab). Docetaxel, Cisplatin, and Irinotecan are traditional chemotherapy drugs. Bevacizumab is an antibody (a protein that attacks a foreign substance in the body). Bevacizumab is believed to stop the formation of new blood vessels that carry nutrients to tumors. Both of the chemotherapy regimens (PCA and TPCA) have been studied in patients with esophageal and gastric cancer, and we are trying to determine if one regimen will keep your cancer from growing and improve how long you can live.

Study Overview

• Status: Completed
• Conditions: Stomach Cancer; Gastric Cancer; Esophageal Cancer
• Intervention / Treatment: Drug: Cisplatin; Drug: Bevacizumab; Drug: Irinotecan; Device: Docetaxel

Detailed Description

OBJECTIVES:

Primary

* To evaluate progression-free survival at 7 months in metastatic esophageal and gastric patients treated with either PCA or TPCA

Secondary

• To determine overall survival
• To determine the response rate (RECIST) in measurable disease patients
• To evaluate type and severity of toxicities associated with each regimen

Exploratory:

• To correlate expression of tumoral and serum VEGF with response and survival
• To correlate TGF alpha levels and tumor microvessel density with clinical activity of the combination of PCA or TPCA
• To examine circulating endothelial cells (CECs) as surrogate markers of antitumor activity of bevacizumab
• To explore if 7/7 and 7/6 UGT1A1 polymorphisms correlate with grade III/IV irinotecan-related diarrhea and neutropenia when irinotecan is given at relatively low dose to patients with esophageal and gastric cancer

DESIGN:

This trial was designed to compare 7-month progression-free survival between arms. The hypothesis was that TPCA would have superior outcome over PCA (70% vs 50%). With 40 eligible patients per arm followed for 1 year there was 80% power to detect a hazard ratio of 0.48 using the log-rank test at a one-sided type I error rate of 5%. Stratification factors were ECOG performance status 0/1 vs 2 and site of primary tumor (gastric vs GE junction/esophageal).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
7-month Progression-Free Survival	7-month progression-free survival is the probability of patients remaining alive and progression-free at 7-months from study entry estimated using Kaplan-Meier methods. Per RECIST 1.0 criteria: progressive disease (PD) is at least a 20% increase in the sum of longest diameter (LD) of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. PD for the evaluation of non-target lesions is the appearance of one or more new lesions and/or unequivocal progression of non-target lesions.	Disease was evaluated radiologically at baseline and every 2 cycles on treatment; Relevant for this endpoint was disease status at 7 months of follow-up.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Survival	Overall survival is defined as the time from study entry to death or date last known alive and estimate using Kaplan-Meier (KM) methods.	Patients in the study cohort were followed up to approximately 2.5 years as of this analysis.
Best Response	Best response on treatment was based on RECIST 1.0 criteria: Complete Response (CR) is complete disappearance of all target lesions; Partial Response (PR) is at least a 30% decrease in the sum of longest diameter (LD) of target lesions, taking as reference baseline sum LD. Both require confirmation no fewer than 4 weeks apart. CR/PR assumes at a minimum incomplete response/stable disease (SD) for the evaluation of non-target lesions and absence of new lesions. Progressive disease (PD) is at least a 20% increase in the sum of longest diameter of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. PD for the evaluation of non-target lesions is the appearance of one or more new lesions and/or unequivocal progression of non-target lesions. Stable disease is defined as any condition not meeting above criteria.	Disease was evaluated radiologically at baseline and every 2 cycles on treatment; Treatment duration was a median of 5 cycles (up to approximately 1 year) in this study cohort as of this analysis..
Overall Response (OR) Rate	Overall response (OR) rate was defined as achieving partial response (PR) or complete response (CR) based on RECIST 1.0 criteria on treatment. Per RECIST 1.0 for target lesions, CR is complete disappearance of all target lesions and PR is at least a 30% decrease in the sum of longest diameter (LD) of target lesions, taking as reference baseline sum LD. To be assigned a status of CR or PR, changes in tumor measurements must be confirmed by repeat assessments performed no fewer than 4 weeks after the response criteria are first met. PR or better overall response assumes at a minimum incomplete response/stable disease (SD) for the evaluation of non-target lesions and absence of new lesions.	Disease was evaluated radiologically at baseline and every 2 cycles on treatment; Treatment duration was a median of 5 cycles (up to approximately 1 year) in this study cohort as of this analysis.
Progression-Free Survival	Progression-free survival based on the Kaplan-Meier method is defined as the duration of time from study entry to documented disease progression (PD) requiring removal from the study or death. Patients alive and progression-free at last follow-up are censored. Per RECIST 1.0 criteria: progressive disease is at least a 20% increase in the sum of longest diameter (LD) of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. PD for the evaluation of non-target lesions is the appearance of one or more new lesions and/or unequivocal progression of non-target lesions.	Disease was evaluated radiologically at baseline and every 2 cycles on treatment; Patients were followed for up to 2.5 years as of this analysis.
