Clinical trials of Herceptin(R) (trastuzumab).

Resistance to HER2-targeted therapy

Production and approval of trastuzumab (Herceptin®) for the treatment of metastatic breast cancer (MBC) was a millstone in antibody-based targeted therapy in the cancer treatment. However, despite the early success in the clinical trials, trastuzumab failed to appreciate the initial attraction due to development of resistance to the drug. The majority of patients who benefit from the drug...

Combining trastuzumab (Herceptin) with hormonal therapy in breast cancer: what can be expected and why?

Hormonal therapy and the humanised anti-HER2 monoclonal antibody trastuzumab (Herceptin) represent one of the oldest and one of the newest treatment modalities for breast cancer, respectively. Recent data have suggested that HER2 overexpression is associated with resistance to hormonal therapy and there is considerable preclinical evidence to support the existence of interaction or 'cross talk'...

Herceptin® (trastuzumab) in HER2-positive early breast cancer: protocol for a systematic review and cumulative network meta-analysis

BACKGROUND Human epidermal growth factor receptor 2-positive (HER2+) breast cancer is an aggressive disease that makes up about 20% of all invasive breast cancers. HER2+ breast cancer is associated with poor prognosis and high mortality rates, but the development of HER2-targeted therapies, such as originator trastuzumab (Herceptin®), has substantially improved patient survival. Numerous clinic...

Herceptin (trastuzumab): adjuvant and neoadjuvant trials.

Cardiotoxicity associated with trastuzumab (Herceptin) therapy in the treatment of metastatic breast cancer.

Trastuzumab (Herceptin) is a humanised monoclonal antibody that specifically targets HER2-positive breast cancer cells. Safety data collected from pivotal trials with trastuzumab indicate that this therapy is generally well tolerated. However trials of the combination of trastuzumab plus chemotherapy, and in particular chemotherapy with anthracyclines, have revealed an elevated incidence of car...
