An Observational Study of Continued Bevacizumab Plus Chemotherapy Until First Progression in Participants With Metastatic Colorectal Cancer (CRC)

Study Overview
=================
Brief Summary
-----------------
This prospective, multicenter, observational study will investigate the effectiveness and safety of bevacizumab in routine clinical practice in participants with metastatic CRC. Participants are to have initiated first-line treatment with fluoropyrimidine-based doublet chemotherapy plus bevacizumab according to the bevacizumab Summary of Product Characteristics (SmPC).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Participants with CRC<br>This is an observational study; thus, no intervention or treatment is required by the protocol. During the study, the treatment will be determined according to the treating physician decision. Eligible participants will be observed for safety and efficacy of continued bevacizumab plus fluoropyrimidine-based doublet chemotherapy treatment in routine clinical practice for 1 year. | Other: Bevacizumab<br>* Bevacizumab at a dose and schedule according to approved label and SmPC. The recommended dose of bevacizumab, administered as an intravenous infusion, is either 5 milligrams per kilogram (mg/kg) or 10 mg/kg of body weight given once every 2 weeks or 7.5 mg/kg or 15 mg/kg of body weight given once every 3 weeks. Bevacizumab is always used in combination with chemotherapy for the treatment of participants with metastatic CRC. It is recommended that treatment be continued until progression of the underlying disease or until unacceptable toxicity.<br>* Other names: Avastin;Combination Product: Chemotherapy<br>* Fluoropyrimidine-based doublet chemotherapy (5-Fluorouracil [5-FU] or capecitabine plus oxaliplatin or irinotecan) as first-line treatment; and continued fluoropyrimidine treatment with or without treatment modification for oxaliplatin or irinotecan, as per treating physician discretion.<br>|
