Study of Aflibercept as Maintenance Therapy Following Induction With Aflibercept in Combination With XELOX, as First-Line Treatment for Metastatic Colorectal Cancer Patient (AMOR)
A Single-Arm, Open Label Study of Aflibercept as Maintenance Therapy Following Induction With Aflibercept in Combination With XELOX, as First-Line Treatment for Metastatic Colorectal Cancer Patient
Primary Objectives:
Study Part 1: To determine the recommended dose for the aflibercept, oxaliplatin and capecitabine (XELOX) combination to be used in the Part 2 of the study.
Study Part 2: To assess the percentage of participants without progression of the disease at 6 months after the start of maintenance therapy with aflibercept single-agent, following the first-line induction therapy with XELOX and aflibercept combination in participants with previously untreated metastatic colorectal cancer.
Secondary Objective:
Study Part 2: Include the evaluation of progression free survival, overall survival, response to treatment, the overall safety (during induction and maintenance therapy) and the assessment of aflibercept pharmacodynamics and biomarkers parameters.

Intervention / Treatment
Detailed Description
The duration of the study for each participant includes a period for screening of up to 3 weeks, study drug administrations every 3 weeks up to disease progression, unacceptable toxicity or participant's refusal of further study treatment, followed by a minimum of 30-day follow-up after the last study treatment administration.
After study treatment discontinuation each participant will be followed-up until death, participant's refusal or end of study (whichever comes first).
This trial is being conducted in Europe, where the INN designation for the study molecule is "aflibercept" and this term is therefore used throughout the synopsis. In the US, the US proper name is "ziv-aflibercept".

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Part 1: Number of Participants With Dose Limiting Toxicities (DLTs)
Time Frame: Cycle 1 (Up to 3 weeks)
|
DLTs were assessed using the national cancer institute (NCI) common terminology criteria for adverse events (CTCAE) version 4.03.
DLTs were defined as any of following AEs: grade 4 neutropenia lasting >7 consecutive days; febrile neutropenia or neutropenic infection; grade 4 thrombocytopenia; grade 3 thrombocytopenia associated with bleeding requiring transfusion; grade 4 non-hematological treatment related event; grade 3 nausea/vomiting or diarrhea lasting >/= 4 days despite corrective measures; grade 3 other non-hematological toxicities: anorexia, fatigue, hypertension only if G4 or not medically controlled and G3 peripheral sensory neuropathy that did not improve to G<2 at time of retreatment; urinary protein excretion of >3.5 gram per 24 hours that did not recover to <2.0 gram per 24 hours within 2 weeks; symptomatic arterial thromboembolic events including cerebrovascular accidents, myocardial infarction, transient ischemic attacks, new onset or worsening of pre-existing angina.

Time Frame: 6 months after the start of maintenance therapy.
|
It describes the number of participants alive without progression at 6 months after the start of Aflibercept maintenance therapy.

Baseline and every 9 weeks up to DP (up to 15 months).
|
Part 2: Progression Free Survival (PFS)
Time Frame: From the date of enrollment up to the date of DP or death, whichever occurred first (up to 15 months).
|
PFS was defined as the time interval from the date of registration into the study to the date of first observation of DP or death (due to any cause), whichever was first.
|
From the date of enrollment up to the date of DP or death, whichever occurred first (up to 15 months).
|
Part 2: Overall Survival (OS)
Time Frame: From the date of enrollment up to the date of death (up to 15 months).
|
OS was defined as the time interval from the date of registration into the study to the date of death due to any cause.
In the absence of confirmation of death, survival time was to be censored at the earliest between the last date the participant was known to be alive and the end of study date.

|
Tumor assessment was performed by abdomino-pelvic computed tomography scan or MRI and chest X-ray or chest CT-scan to assess the disease status at baseline and then every 9 weeks during study treatment up to DP. Target lesions were evaluated using RECIST version 1.1, wherein CR = disappearance of all target lesions; PR = 30% decrease in the sum of the LD of target lesions taking as reference the baseline sum LD.
|
Baseline and every 9 weeks up to end of study completion (15 months).
