1. What is Vastaloma and what is it used for
Vastaloma contains the active substance fulvestrant, which belongs to a group of medicines called estrogen receptor antagonists. Estrogens, female sex hormones, can sometimes influence the development of breast cancer.
Vastaloma is used:
- as a single medicine, in the treatment of postmenopausal women with a certain type of breast cancer called hormone receptor-positive breast cancer, which is locally advanced or has spread to other parts of the body (metastases) or
- in combination with palbociclib in the treatment of women with a certain type of breast cancer called hormone receptor-positive, human epidermal growth factor receptor 2 (HER2) negative breast cancer, which is locally advanced or has spread to other parts of the body (metastases). Women who have not yet reached menopause will also receive a medicine called a luteinizing hormone-releasing hormone (LHRH) agonist.
