PRIMARY outcome

Timeframe: Up to 65 months

Population: All participants who received at least 1 dose of study drug and underwent subsequent safety assessment were considered for the safety analysis.

An AE was considered any unfavorable and unintended sign, symptom, or disease associated with the use of the study drug, whether or not considered related to the study drug.

Unresectable CRC at Baseline
Participants with unresectable metastatic CRC at baseline received bevacizumab in combination with chemotherapy according to registered indication in routine clinical practice until progression of disease, unacceptable toxicity, lost to follow up, death, or withdrawal of informed consent..
Percentage of Participants With At Least One Adverse Event (AE)
15.2 percentage of participants

SECONDARY outcome

Timeframe: Up to 65 months

Population: All participants who received at least 1 dose of study drug were included in this analysis.

Per RECIST, CR was defined as the disappearance of all target and non-target lesions and normalization of tumor marker level; PR was defined as at least a 30 percentage (%) decrease in the sum of the longest diameter of target lesions, taking as reference the screening sum longest diameter; SD for target lesions was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum longest diameter since the treatment started and SD for non-target lesions defined as persistence of 1 or more non-target lesion(s) or/and maintenance of tumor marker level above the normal limits. PD was defined as at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter recorded since the treatment started or the appearance of 1 or more new lesions (target and nontarget lesions) or the unequivocal progression of existing non-target lesions.

SECONDARY outcome

Timeframe: Up to 65 months

Population: Included participants who received at least 1 dose of study drug and had postbaseline tumor assessment.

Per RECIST, PD was defined as at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter recorded since the treatment started or the appearance of 1 or more new lesions (target and nontarget lesions) or the unequivocal progression of existing non-target lesions.

76.5 percentage of participants

SECONDARY outcome

Timeframe: Up to 65 months

Population: Included participants who received at least 1 dose of study drug and had postbaseline tumor assessment.

PFS was defined as the time from the date of informed consent until the date when the participant had progression of disease or died due to any cause. Participants who left the study for reasons other than progression of the disease were censored at the time of their last tumor assessment. Per RECIST, PD was defined as at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter recorded since the treatment started or the appearance of 1 or more new lesions (target and non-target lesions) or the unequivocal progression of existing non-target lesions.
