Oxaliplatin, Capecitabine and Avastin for Metastatic Esophagogastric Adenocarcinoma (XAGastric)
2015年1月28日 更新者：Duke University
A Phase ll Study of Oxaliplatin, Capecitabine, and Bevacizumab in the Treatment of Metastatic Esophagogastric Adenocarcinomas
The purpose of this study is to evaluate the progression free survival of capecitabine (Xeloda), oxaliplatin and bevacizumab (Avastin) in previously untreated metastatic esophagogastric adenocarcinomas.
調査の概要
詳細な説明
The number of new cases of esophageal and gastric cancers in the United States in 2005 is 14520 for esophageal cancer and 21860 for gastric cancer. Unfortunately, esophageal and gastric cancers will also account for 13570 and 11550 deaths, respectively, in 2005. The 5 year survival rates for metastatic gastroesophageal, GE junctional, and gastric cancers are less than 5%. The major current treatment modality for patients with advanced esophageal, GE junctional, and gastric adenocarcinomas is systemic chemotherapy.
We seek to investigate the efficacy of capecitabine and oxaliplatin in combination with bevacizumab as first line treatment for metastatic esophagogastric cancers. The choice of capecitabine and oxaliplatin is made to develop a user-friendly biologically-based regimen, offering patients oral capecitabine in place of continuous 5FU infusion pumps. Since capecitabine can be given crushed this regimen may both be active and user-friendly. Preliminary data in colorectal cancer suggest that the regimen of capecitabine, oxaliplatin, and bevacizumab has comparable activity to FOLFOX-bevacizumab. The goal of the proposed regimen is to define a capecitabine and oxaliplatin-based regimen that optimizes biological approaches over cytotoxic approaches. The addition of bevacizumab to chemotherapy regimens for metastatic colorectal cancer, metastatic non-small cell lung cancer, and metastatic breast cancer has shown to improve response rates and overall survival. If active, this regimen could serve as a first line comparator to the capecitabine, oxaliplatin, and epirubicin combination. This approach will also help to simplify regimen development across gastrointestinal cancers.
In addition to the primary efficacy endpoint of this protocol, several correlative endpoints will also be examined in an exploratory manner. The importance of developing blood-based and tumor biomarkers has been extensively reviewed. However, the role of such predictive markers has not been well studied for XELOX-A. This information is important since it may help define which populations are most likely to benefit and most likely to suffer significant toxicity from this important GI cancer regimen. This biomarker approach may also help understand and define mechanisms of sensitivity, resistance, and toxicity that may be used to guide future hypothesis-driven studies designed to improve the efficacy and safety of this regimen. The correlative biomarker endpoints include serum, plasma and urine biomarkers (e.g. VEGF and bFGF), a wound healing model of angiogenesis, and tumor biopsy studies .

Capecitabine will be administered orally at a twice daily dose of 850 mg/m2 (equivalent to a total daily dose of 1700 mg/m2) given days 1-14 of the three week cycle. Oxaliplatin will be administered at the dose of 130 mg/m2 given as a 2-hour intravenous infusion on day 1 of a three week cycle. Bevacizumab will be administered at a dose of 15 mg/kg given as a 30-90 minute intravenous infusion on day 1 of a three week cycle following the administration of oxaliplatin. |

Median Progression-Free Survival (PFS)
時間枠：5 years from study start date
|
Time in months from the start of study treatment to the date of first progression (PD) according to the RECIST criteria, or death due to any cause.
PER RECIST, a PD is indicated when there is at least a 20% increase in the sum of the longest diameters from target lesions relative to the smallest sum recorded since treatment is initiated.
Median PFS was estimated using a Kaplan-Meier curve, and is the time at which 50% of patients remain alive without disease progression.

To Assess the Safety and Tolerability of the Combination of Bevacizumab, Oxaliplatin and Capecitabine in Patients With Previously Untreated Metastatic Esophagogastric Adenocarcinoma
時間枠：Every 21 days

Number of subjects who experienced an adverse event
|
Every 21 days

Response Rate
時間枠：Every 9 weeks for up to 1 year
|
The proportion of patients for whom the best overall response is complete response (CR) or partial response (PR).
A CR occurs when all lesions disappear; whereas, a PR is indicated when there is at least a 30% decrease in the sum of the longest diameters (LD) of the target lesion.
A PD (progressive disese) occurs when there is at least a 20% increase in the sum of the LD relative to the smallest sum LD recorded since treatment is initiated.
Disease is considered stable if there is no response and no PD.
All patients were assigned a best response for inclusion in this calculation in accordance with the protocol.

Every 9 weeks for up to 1 year

Median Survival
時間枠：5 years after study start date
|
Time in months from the start of study treatment to date of death due to any cause.
Median survival was estimated using a Kaplan-Meier curve and is the time point at which 50% of patients remain alive.
