Toco-CoR: Tocotrienol and Bevacizumab in Metastatic Colorectal Cancer
Study Details
Study Description
Brief Summary
This double blind, randomized phase II trial will investigate whether the addition of tocotrienol will improve the effect and lower the toxicity of standard chemotherapy and bevacizumab. Half of the patients will receive tocotrienol and the other half placebo. Treatment is planned for a period of maximum six months and will be discontinued earlier in case of progression or unacceptable toxicity.
