Summary
Researchers are looking for a better way to treat women with, or at high risk for developing hormone-receptor positive breast cancer, who have vasomotor symptoms (VMS), a condition of having hot flashes caused by anti-cancer therapy. VMS, also called hot flashes, are very common medical problems in women with hormone-receptor (HR)-positive breast cancer, who are receiving anti-cancer therapy. HR-positive breast cancer is a type of breast cancer, which has hormone-receptors (proteins) for female sex hormones estrogen and/or progesterone. These hormone-receptors may attach to hormones like estrogen and progesterone and thereby help cancer cells to grow and to spread. Treatments that stop these hormones from attaching to these receptors are currently used to slow or stop the growth of HR-positive breast cancer. It is already known that women with HR-positive breast cancer benefit from this treatment. However, hot flashes are common medical problems related to this therapy. They negatively affect quality of life of many women and may lead to discontinuation (stopping) of this therapy. The study treatment, elinzanetant is being developed to treat hot flushes. It works by blocking a subs
