A Study of Avastin (Bevacizumab) and Oxaliplatin Plus Xeloda (Capecitabine) in Patients With Advanced Colorectal Cancer.

Percentage of participants with OR was defined as the percentage of participants who achieved complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST). CR was defined as disappearance of all target lesions, non-target lesions, and normalization of tumor marker level. PR was defined as greater than or equal to (≥)30 percent (%) decrease under baseline of the sum of the longest diameter (LD) diameters of all target lesions. No unequivocal progression of non-target disease. No new lesions. Complete and partial responses must have been confirmed no less than 4 weeks after the criteria for response were first met.

Best response recorded from the start of treatment until disease progression. Based on assessment of CR, PR, stable disease (SD), or progressive disease (PD), according to RECIST. CR: disappearance of all target lesions, non-target lesions, and normalization of tumor marker level. PR: ≥30% decrease under baseline of the sum of the LD diameters of all target lesions. CR and PR persist on repeat imaging study at least 4 weeks after initial documentation. SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. Reference is the smallest sum LD. PD: at least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum longest diameter recorded or the appearance of one or more new lesions.

Duration of overall response (CR or PR) was calculated only for participants of the ITT population whose best overall response was CR or PR based on RECIST criteria. Duration of overall response was defined as the time from the date of the first assessment of CR or PR status until the date of progression or death. Data for participants who were alive without any objectively documented disease progression at the end of the study were censored as of the date of last contact.

Duration of overall response was defined as the time from the date of the first assessment of CR or PR status until the date of progression or death. Data for participants who were alive without any objectively documented disease progression at the end of the study were censored as of the date of last contact. Mean time to event was estimated using the Kaplan-Meier method.

Duration of stable response (CR, PR, or stable disease [SD]) was calculated only for participants of the ITT population whose best overall response was CR, PR, or SD based on RECIST criteria. Duration of overall response was defined as the time from the date of the first assessment of CR, PR, or SD status until the date of progression or death. Data for participants who were alive without any objectively documented disease progression at the end of the study were censored as of the date of last contact.

Duration of stable response (CR, PR, or SD) was calculated only for participants of the ITT population whose best overall response was CR, PR, or SD based on RECIST criteria.

Data for participants who were alive without any objectively documented disease progression at the end of the study were censored as of the date of last contact. Mean time to event was estimated using the Kaplan-Meier method.

TTF was defined as the time in months from Day 1 until discontinuation of treatment for any reasons. These reasons included: death due to any cause, treatment toxicity (adverse event), insufficient therapeutic response (progression of disease), failure to return (lost to follow-up), refusing treatment (participant non-compliance), being unwilling to cooperate and withdrawing consent (participant withdrew consent).

TTP was defined as the time time in months from Day 1 until the date of first documented progressive disease, or death due to any cause. Data for participants who were alive without disease progression at the end of study, or who were non-responder participants (without tumor assessment after baseline) were censored at Day 1.

Mean TTP was estimated using the Kaplan-Meier method.

OS was defined as the time in months from Day 1 until the date of death due to any cause. Data for participants who were alive at the end of the study were censored at the date of the last available follow-up visit.
