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

Hoffmann-La Roche300 enrolled

Overview

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).

Conditions

Colorectal Cancer

Interventions

BevacizumabOTHER

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.

ChemotherapyCOMBINATION_PRODUCT
