Current Treatment Options

The typically treatment for metastatic cancer is chemotherapy. Many drugs have activity in breast cancer, achieving response rates of 30-50%, however, response durations are generally short and on the order of months.  Combination regimens and high dose chemotherapy have been tried, but with little additional benefit for most patients.  

HER2 positive breast cancer used to have a worse prognosis, but now with advent of  trastuzumab supplemented treatment, it now has a better prognosis than the common forms of breast cancer. Herceptin is used in combination with most chemotherapy agents, and has boosted response rates to 50-70%, however, most patients will relapse. Trastuzumab is a monoclonal antibody designed to target and block the function of the HER-2 receptor which is positively correlated to tumor growth.

Bavarian Nordic believes, that its vaccine candidate, MVA-BN® HER2, if approved, could be a valuable supplement to existing therapies in the treatment of HER2 breast cancer patients.
