  Purpose

The purpose of this study is to determine whether

  • Paclitaxel and bevacizumab showed improved PFS compared to paclitaxel alone. Recent results of the AVADO study report a similar result for the combination of docetaxel and bevacizumab. The AVADO study furthermore confirmed the dose of 15 mg/kg BW of bevacizumab.
  • As in metastatic breast cancer (MBC) poly-chemotherapies are frequently used, regimens with bevacizumab and at least 2 cytotoxic agents should be investigated.
  • Docetaxel and capecitabine showed a benefit in PFS and survival. This combi- nation is therefore a reasonable choice.
  • Dose of capecitabine and docetaxel should be reduced to 1800 mg/m2 and 75 mg/m2 to improve tolerability without compromising efficacy.
  • Paclitaxel and capecitabine is well tolerated and showed a PFS of 10.3 months.
  • Docetaxel 100 mg/m2 as monotherapy in MBC not very often used b/o toxicity. 75 mg/m2 much more accepted in daily practice. Better comparability with DBX, if both arms have 75mg/m2 docetaxel as assumed.

Primary Outcome Measures:
  • Progression free survival (PFS) [ Time Frame: 10 month ] [ Designated as safety issue: Yes ]
    The PFS time is defined as time from randomization to locoregional or systemic recurrence, second malignancy or death due to any cause; censored observations will be the last date of: "death", "last tumor assessment", "last follow up date" or "last date in drug log"


Secondary Outcome Measures:
  • To determine the objective response rate in both arms [ Time Frame: End of Study ] [ Designated as safety issue: Yes ]
  • To determine the duration of response in both arms. [ Time Frame: End of Study ] [ Designated as safety issue: Yes ]
  • To determine the Time to Progression (TTP) in both arms. [ Time Frame: End of Study ] [ Designated as safety issue: Yes ]

  • To determine the overall survival rate 3 years after "Last Patient In". [ Time Frame: End of Study ] [ Designated as safety issue: Yes ]
  • To determine PFS and TTP response rates in patient's ≥ age 65. [ Time Frame: End of Study ] [ Designated as safety issue: No ]
  • To determine the toxicity and compliance in both arms. [ Time Frame: End of Study ] [ Designated as safety issue: Yes ]
