Studien-Informationen

Detailed Description:

Especially for diseases that are not curable such as metastatic breast cancer (MBC), the

maintenance of quality of life is one of the main aims of treatments. Adverse events are

well-known side effects of any cytostatic treatment and impact the patients' quality of life.

Therefore, new treatment options are developed that should stop or at least slow down

metastatic spread of cancer without causing negative side effects in terms of high-grade

adverse events. For patients with hormone-receptor positive and HER2 positive MBC the

combination of HER2-targeted therapy with endocrine therapy has already been proven to be an

effective and in many cases valuable alternative to the combination of HER2-targeted therapy

with chemotherapy. The high relevance of HER2-neu-targeted/endocrine treatment combinations

derives from the fact that potential chemotherapy-related toxicity can be avoided, which in

turn positively affects quality of life. Clinical trials suggest an additional benefit when a

CDK4/6 inhibitor is added to the combination of endocrine therapy and anti HER2 treatment.

DETECT V is a randomized phase III study comparing the safety and efficacy of trastuzumab

plus pertuzumab and the CDK 4/6 inhibitor ribociclib in combination with either endocrine

therapy or chemotherapy.
