|Official Title:||Phase II Trial of Trastuzumab (Herceptin), Bevacizumab, and Docetaxel (Taxotere) Trial in Stage IV Metastatic Breast Cancer (MBC) Patients|
- The primary objectives are to determine the progression-free survival (PFS) and to evaluate safety of the trastuzumab, bevacizumab and docetaxel regimen. [ Time Frame: up to 12 months ] [ Designated as safety issue: Yes ]
- Changes in CTCs and CECs as predictors of PFS and clinical benefit [ Time Frame: up to 12 months ] [ Designated as safety issue: Yes ]
- Overall clinical benefit rate (CR+PR+SD) [ Time Frame: up to 12 months ] [ Designated as safety issue: Yes ]
|Study Start Date:||June 2007|
|Estimated Primary Completion Date:||December 2015 (Final data collection date for primary outcome measure)|
Experimental: Trastuzumab, Bevacizumab, and Docetaxel
Trastuzumab [6mg/kg], Bevacizumab [15mg/kg], and Docetaxel [75 mg/M²]
administered every three weeks on day 1, every 21 days. The dose given will be 6 mg/kg. The initial loading dose is 8mg/kg and is administered as a 90-minute infusion. Thereafter, the maintenance dose is 6mg/kg every three weeks administered as a 30 minute infusion (unless the treating physician indicates a longer infusion duration is warranted). Trastuzumab is given prior to bevacizumab. Trastuzumab is to be continued until disease progression or unacceptable toxicity.
Other Name: HerceptinDrug: Bevacizumab
administered every three weeks on day 1, every 21 days. The dose given will be 15 mg/kg. The initial dose is administered over 90 minutes. If the first infusion is well tolerated, the second dose is given over 60 minutes, and if that is well tolerated, then subsequent doses may be given over 30 minutes. Avastin is given after trastuzumab and prior to docetaxel.
Other Name: AvastinDrug: Docetaxel
administered every three weeks on day 1, every 21 days. The dose given will be 75 mg/M². All doses of docetaxel are administered over 60 minutes. Docetaxel is given after trastuzumab and bevacizumab.
Other Name: Taxotere
Rationale: Antibodies are proteins that are normally part of the immune system that bind to foreign agents in the body. Researchers manufacture antibodies outside of the human body that bind to specific targets such as proteins in cancer cells. Herceptin is a monoclonal antibody that binds to the human epidermal growth factor receptor (HER-2), and can kill HER2-positive cancer cells. Herceptin is used to treat breast cancer that is HER2-positive, and has spread after treatment with other drugs. Bevacizumab is a signal transduction inhibitor that works by preventing the growth of new blood vessels from surrounding tissue into tumors. Bevacizumab specifically inhibits the vascular endothelial growth factor (VEGF), a substance made by cells that stimulates new blood vessel formation. Research indicates that HER-2 signaling helps to induce VEGF expression. Therefore, cancer treatments targeting both HER-2 and VEGF may improve anti-cancer efficacy in patients. Docetaxel is a chemotherapy agent used against breast and other types of cancer. The current study builds on previous research suggesting the safety and potential for efficacy with combination trastuzumab, bevacizumab, and docetaxel.
Purpose: The primary objectives are to determine the progression free survival and evaluate the safety of trastuzumab, bevacizumab, and docetaxel. Secondary objectives are to assess early changes in circulating tumor cells and circulating endothelial cells as predictors of progression free survival and clinical benefit, as well as to determine the overall clinical benefit rate.
Treatment: Study participants will be given trastuzumab, bevacizumab, and docetaxel. All study drugs will be given through intravenous infusions once every 21 days. A cycle is considered 3 weeks. A minimum of 6 study treatment cycles is required unless study participants experience disease growth or intolerable toxicity. The decision to stop docetaxel after 6 cycles is up to the discretion of the treating physician and the patient. Study participants who are deriving a benefit from the study drugs may continue on trastuzumab and bevacizumab alone. Several tests and exams will be given throughout the study to closely monitor study participants.
