Brief Summary:

Investigating the efficacy of maintenance and reinduction treatment or no treatment and watchful waiting in subjects with inoperable or irresectable and non-progressive metastatic colorectal cancer after first line induction treatment for 24 weeks with a fluoropyrimidine-, oxaliplatin- and bevacizumab-based chemotherapy.

The maintenance treatment with capecitabine or 5-FU/folinic acid and bevacizumab will be compared with a maintenance treatment with bevacizumab alone or no maintenance treatment. Reinduction treatment will be done in case of progression.

Condition or disease Intervention/treatment Phase
Colorectal Neoplasms Drug: 5-Fluorouracil, Folic acid, Capecitabine; Bevacizumab Phase 3

Detailed Description:

Chemotherapy and bevacizumab represent a standard of care in treatment of metastatic colorectal cancer. Until now, continuation of chemotherapy - and bevacizumab - represents the standard of care in colorectal cancer treatment. However, since the OPTIMOX1 trial showed an equivalent duration of disease control for a de-escalation / maintenance / reintroduction strategy compared with a treatment until progression strategy for oxaliplatin-based chemotherapy, the question is whether this strategy might apply also to bevacizumab in combination with chemotherapy. Furthermore, with the introduction of bevacizumab, there are new options for a maintenance treatment which should be evaluated.

As the continuation of chemotherapy plus bevacizumab until disease progression has to be regarded as standard of care, the question is whether a de-escalation of treatment intensity or even withdrawal of treatment ("drug holiday") after a certain treatment period will not be inferior with respect to resulting time with tumor control, but allow patients a period with less toxicity and gain of quality of life.

      • Basal and squamous cell carcinoma of the skin
      • in situ carcinoma of the cervix
      • Other malignant disease without recurrence after at least 5 years of follow-up
    • No severe internal disease (insufficiently treated or uncontrolled arterial hypertension, haemoptoe, New York Heart Association (NYHA) grade II or greater congestive heart failure, symptomatic coronary heart disease, myocardial infarction (= < 12 months prior to inclusion), serious cardiac arrhythmia requiring medication, peripheral arterial occlusive disease stage II or greater, uncontrolled severe disease)
    • No history or evidence upon physical examination of CNS disease unless adequately treated (e.g., primary brain tumour, seizure not controlled with standard medical therapy, brain metastases or history of stroke).
