Clinical Trial Summary

To investigate bevacizumab in combination with carboplatin and capecitabine for patients with unresectable or metastatic GEJ or gastric cancers. We hope that by adding bevacizumab to standard chemotherapy for this patient population we will improve Progression Free Survival by 90% over historical controls.


Description:

Primary Objectives: To investigate if the addition of Bevacizumab to standard chemotherapy for metastatic or unresectable GEJ and gastric adenocarcinoma will improve PFS by 90% over historical controls. Secondary Objectives: - Assess toxicities using CTCAE v3.0 - Evaluate overall survival (OS) using Kaplan-Meier analysis - Evaluate objective response rate (RR) by RECIST criteria - Explore biomarkers of tumor response: CEA, CA 19.9, and serum VEGF - Bank serum and tissue for future correlative studies - Evaluate CT Perfusion to predict early therapeutic response to combination chemotherapy and anti-angiogenic therapy (OPTIONAL).

Eligibility Inclusion Criteria: Subjects must be treated at Stanford University Medical Center for the entire length of study participation. 1. Patients with histologically or cytologically confirmed adenocarcinoma of the GEJ or stomach. 2. Patients must be deemed unresectable due to involvement of critical vasculature or adjacent organ invasion. If unresectable, patients must show evidence of disease progression prior to enrollment. 3. Patients with prior surgical resection who develop radiological or clinical evidence of metastatic cancer do not require separate histological or cytological confirmation of metastatic disease unless an interval of > 5 years has elapsed between the primary surgery and the development of metastatic disease. Clinicians should consider biopsy of lesions to establish diagnosis of metastatic disease if there is substantial clinical ambiguity regarding the nature or source of apparent metastases. 4. Prior carboplatin as neoadjuvant or adjuvant therapy will be allowed if >= 6 months from the time of study entry. 5. If patients use aspirin (>325mg/day) or NSAIDS at the time of enrollment, they must have a 10 day washout period prior to beginning protocol treatment. 6. Low molecular weight heparin (or its equivalent, excluding warfarin) will be allowed for treatment of venous thromboembolic events if patients have no evidence of bleeding on full-dose anticoagulation. 7. Patients must have a primary or metastatic lesion measurable in at least one dimension by Modified RECIST criteria (see Section 11.2.3) within 4 weeks prior to entry of study 8. Patients must have ECOG performance status of 0-1 9. Patients must be >= 18 years of age 10.

Outcome

Type Measure Description Time frame Safety issue
Primary Progression-Free Survival (PFS) Tumor progression was assessed according to the Response Evaluation Criteria in Solid Tumors Criteria (RECIST v1.1), presented below.
Complete Response (CR) = Disappearance of all target lesions
Partial Response (PR) = = 30% decrease in the sum of the longest diameter of target lesions
Objective Response (OR) = CR + PR
Progressive disease (PD) = 20% increase in the sum of the longest diameter of target lesions, and/or the appearance of one or more new lesion(s)
Stable disease (SD) = Small changes that do not meet any of the above criteria.
Progression-Free Survival is assessed as the number of evaluable participants who were alive without disease progression at 1 year. Participants without out assessment at 12 months will not be included.
12 months
Secondary Adverse Events = Grade 3 and Related to Bevacizumab Toxicity was assessed as the number of adverse events = Grade 3 and also possibly, probably, or definitely related to bevacizumab. The outcome is reported as the total number of applicable events, and as the number of events that were a hematologic toxicity; a non-hematologic toxicity; which are numbers without dispersion. 12 months
Secondary Overall Survival (OS) Overall survival (OS) will be assessed from time from the date of enrollment to the date of death due to any cause or the last date the patient was known to be alive (censored observation) at the date of data cutoff for the final analysis. The outcome is presented as the median survival in days with standard deviation. 7.5 years
Secondary Objective (Overall) Therapeutic Response Tumor response was assessed per the Response Evaluation Criteria in Solid Tumors Criteria (RECIST v1.1) for target lesions, and assessed by physical measurement; magnetic resonance imaging (MRI); computed tomography (CT), positron emission tomography (PET)-CT; and/or X-rays/radiologic scan. Response was determined based on the criteria below.
Complete Response (CR) = Disappearance of all target lesions
Partial Response (PR) = = 30% decrease in the sum of the longest diameter of target lesions
Objective Response (OR) = CR + PR
Progressive disease (PD) = 20% increase in the sum of the longest diameter of target lesions, and/or the appearance of one or more new lesion(s)
Stable disease (SD) = Small changes that do not meet any of the above criteria The outcome is provided as the number of participants who achieved each of the defined responses, with objective (overall) response defined as the sum of CR and PR. The outcome is reported as values without dispersion.
12 months
Secondary CEA and CA 19.9 Tumor Response Biomarkers The detected blood levels for tumor biomarkers CEA and CA 19.9 were to be correlated to the results for progression-fee survival (PFS), with the outcome presented as the median with standard deviation. 9 weeks
Secondary Vascular Endothelial Growth Factor Tumor Response Biomarker The detected blood levels for tumor biomarker vascular endothelial growth factor (VEGF) were to be correlated to the results for progression-fee survival (PFS), with the outcome presented as the median with standard deviation. 9 weeks
