Trial Outcomes & Findings for Ph II of Capecitabine, Carboplatin & Bevacizumab for Gastroesophageal Junction & Gastric Carcinoma (NCT NCT00780494)

NCT ID: NCT00780494

Last Updated: 2025-01-14

Results Overview

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.

PRIMARY outcome

Timeframe: 12 months

Population: Those participants who did not receive follow-up at 12 months were considered lost-to-follow-up and not evaluable for progression, and were censored from the analysis.

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.

9 Participants

SECONDARY outcome

Timeframe: 12 months

Population: All participants were included in this analysis.

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.

SECONDARY outcome

Timeframe: 7.5 years

Population: Data were available for all participants. Participants remaining alive were censored at last date assessed.

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.

SECONDARY outcome

Timeframe: 12 months

Population: Data for clinical response was not available for all participants. Response data are only reported for participants for whom response is known.

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.

SECONDARY outcome

Timeframe: 9 weeks

Population: Based on the objective results, it was determined that the any results from tumor biomarker analyses would be of little value, and the measurement for tumor biomarkers in the collected samples were not conducted. Accordingly, there is no data to be analyzed.

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.

SECONDARY outcome

Timeframe: 9 weeks

Population: Studies published during the conduct of this study demonstrated that this assessment was not useful, and the samples were not collected. Accordingly, there is no data to be analyzed.

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.
