NCT00561470 · STUDY IN CONTEXT

Aflibercept Versus Placebo in Combination With Irinotecan and 5-FU in the Treatment of Patients With Metastatic Colorectal Cancer After Failure of an Oxaliplatin Based Regimen

Draft scope assessment: narrower. Linked by condition-string match at the cancer-entity level. The study's eligibility - stage, biomarker, treatment line and prior therapy - has not been reconciled against this page's definition, so its population is narrower than this page in ways not yet recorded. The condition was transformed or resolved through the terminology hierarchy to reach this cancer type, so the link itself is a candidate a reviewer must confirm. Found because this study's registry identifier is printed in an FDA approval notice, an FDA product label or an NCI summary held by this site. The citing document and the exact position of the identifier inside it are recorded. Being cited is not a statement that the study supports this treatment.

primary · POSTED

Overall Survival was the time interval from the date of randomization to the date of death due to any cause. Once disease progression was documented, participants were followed every 2 months for survival status, until death or until the study cutoff date, whichever came first. The final data cutoff date for the analysis of OS was the date when 863 deaths had occurred (07 February 2011). OS was estimated using the Kaplan-Meier method, and the Hazard Ratio was estimated using the Cox Proportional Hazard Model.

Intent-to-treat population (ITT) - all participants who gave informed consent and were randomized.

→

secondary · POSTED

PFS was the time interval from the date of randomization to the date of progression, or death from any cause if it occurs before tumor progression is documented. To evaluate disease progression, copies of all tumor imaging sets were systematically collected and assessed by the IRC. PFS was analyzed using the Kaplan-Meier method, and the Hazard Ratio was estimated using the Cox Proportional Hazard Model. The analysis for PFS was performed as planned when 561 deaths (OS events) had occurred.

Intent to Treat (ITT) population included all participants who gave informed consent and were randomized.

secondary · POSTED

The overall ORR was the percentage of evaluable participants who achieved complete response \[CR\] or partial response \[PR\] according to RECIST criteria version 1.0. * CR reflected the disappearance of all tumor lesions (with no new tumors) * PR reflected a pre-defined reduction in tumor burden Tumors were assessed by the IRC using Computerized Tomography (CT) scans or Magnetic Resonance Imaging (MRI) scans; and an observed response was confirmed by repeated imaging after 4 - 6 weeks.

The evaluable patient population (EPP) for tumor response included all randomized participants with measurable disease at study entry, as per IRC evaluation, and with at least one valid post-baseline tumor evaluation.

→

secondary · POSTED

All AEs regardless of seriousness or relationship to study treatment, spanning from the first administration of study treatment until 30 days after the last administration of study treatment, were recorded, and followed until resolution or stabilization. The number of participants with all treatment emergent adverse events (TEAE), serious adverse events (SAE), TEAE leading to death, and TEAE leading to permanent treatment discontinuation are reported.

The safety population was the subset of the ITT population that took at least one dose of study treatment. Analyses was based on the treatment actually received (any participant who received at least one dose of aflibercept, even when receiving the rest of study treatment with placebo, was counted in the aflibercept treatment arm).

→

secondary · POSTED

Serum samples for immunogenicity assessment were analyzed using a bridging immunoassay to detect ADA. Positive samples in the ADA assay were further analyzed in the NAb assay using a validated, non-quantitative ligand binding assay.

Immunogenicity population included all participants who were treated and tested for immunogenicity at least once post-baseline.
