Study information
Scientific title
Acronym
HERTAX, BOOG 2002-02
Study hypothesis
Although combined treatment will probably lead to higher response rates, sequential treatment may result in a similar time to progression in the presence of less side effects and a better quality of life in a significant number of patients.
Ethics approval
Received from the local medical ethics committee
Study design
Multicentre, open-label, randomised, active controlled, parallel group trial
Primary study design
Interventional
Secondary study design
Randomised controlled trial
