A Study of Capecitabine (Xeloda) and Bevacizumab as a First-line Therapy in Patients With Metastatic Colorectal Cancer

PFS is defined as the time from randomization to disease progression (PD) or death due to any cause. Participants with neither disease progression nor death were censored at the last date of the last tumor assessment that confirmed that their disease had not progressed. Participants who underwent surgical resection with curative intent without prior progression were censored at the date of surgery. PFS was analyzed on the basis of the tumor response assessments made by the IRC. Non-inferiority analysis that followed the general approach took into account all tumor assessments obtained during the primary study treatment phase, the post-study treatment phase and those obtained during the follow-up phase. Non-inferiority of the XELOX-containing arms was compared with the FOLFOX-4-containing arms.

Superiority of the bevacizumab-containing arms was compared with the placebo-containing arms.

PFS is defined as the time from randomization to disease progression (PD) or death due to any cause. The on-treatment analysis included only tumor assessments and death events that occurred no later than 28 days after the last confirmed intake of any study medication in the primary study treatment phase. Participants who did not have an event during this interval were censored at the date of the last tumor assessment within this time window, or on day 1 if no tumor assessment was available after baseline. Participants who underwent surgical resection with curative intent without prior progression within 28 days after the last confirmed intake of any study medication in the primary study treatment phase were censored at the date of surgery. The on-treatment approach excluded the possible impact of other treatments that might have been started before disease progression. Non-inferiority of the XELOX-containing arms was compared with the FOLFOX-4-containing arms.

PFS is defined as the time from randomization to disease progression (PD) or death due to any cause. Participants who underwent curative surgery after experiencing a sufficient shrinkage of their tumor were not censored at the date of surgery, but any relapse, new occurrence of colorectal cancer, or death was considered as an event. Non-inferiority analysis that followed the general approach took into account all tumor assessments obtained during the primary study treatment phase, the post-study treatment phase and those obtained during the follow-up phase. Non-inferiority of the XELOX-containing arms was compared with the FOLFOX-4-containing arms.

Superiority of the BV-containing arms was compared with the chemotherapy alone arms.

Overall survival was defined as the time from the date of randomization to the date of death. Participants who were not reported to have died at the time of the clinical cut-off date for the analysis were censored using the date they were last known to be alive. Non-inferiority of the XELOX-containing arms was compared with the FOLFOX-4-containing arms.

According to the RECIST criteria, BOR in an individual participant was defined as the best response recorded from the start of the treatment until disease progression or recurrence. Only tumor assessments as assessed by the investigator and made up to and including 28 days after last intake of study medication in the primary study treatment phase not later than date of first curative surgery were included in these analyses. Responders were defined as the percentage of participants with a confirmed best overall response of complete response (CR) or partial response (PR). Non-inferiority of the XELOX-containing arms was compared with the FOLFOX-4-containing arms.

According to the RECIST criteria, the BOR in an individual participant was the best response recorded from the start of the treatment until disease progression/recurrence (taking the smallest measurements recorded since the baseline assessment as a reference for PD). The BOR as assessed by the IRC was determined based on tumor assessments that were made up to and including 28 days after last intake of study medication in the primary study treatment phase. Responders were defined as the percentage of participants with a complete response (CR) or partial response (PR). Non-inferiority of the XELOX-containing arms was compared with the FOLFOX-4-containing arms.

Time to treatment failure was defined as the time from the date of randomization to the date of discontinuation of the primary study treatment phase due to adverse event/intercurrent illness, insufficient therapeutic response, death, failure to return, refusing treatment/being unwilling to cooperate, or withdrawing consent; discontinuation of the post study treatment phase due to adverse event, progressive disease, death, participant refusal/administrative reasons, or withdrawing consent; documented disease progression; or death due to any cause, whichever occurred first. The general approach took into account all tumor assessments obtained during the primary study treatment phase, the post-study treatment phase and those obtained during the follow-up phase.The on-treatment approach included only tumor assessments and deaths that occurred no later than 28 days after the last confirmed intake of any study medication in the primary study treatment phase only.

For participants whose BOR was CR or PR, time to response was measured as the time from randomization to the first time when the measurement criteria for CR or PR (whichever status was recorded first) was met. It was based on tumor assessments made by the investigators according to the RECIST criteria. Results were reported as the number of participants achieving a response in 8 time categories from Week 1 to Week 54. Non-inferiority of the XELOX-containing arms was compared with the FOLFOX-4-containing arms.

Duration of overall response was measured from the time that measurement criteria were first met for CR or PR (whichever status was recorded first) until the first date when progressive disease or death was documented. It was based on tumor assessments made by the investigators according to the RECIST criteria. Participants who neither progressed nor died were censored at the date of the last tumor assessment. Participants undergoing surgical resection with curative intent were censored at the date of surgery. Non-inferiority of the XELOX-containing arms was compared with the FOLFOX-4-containing arms.
