Description:
Fulvestrant Acetate (trade name Faslodex, by AstraZeneca) is a drug treatment of hormone receptor-positive metastatic in postmenopausal women with disease progression following anti-estrogentherapy. It is a completeestrogen receptor antagonist with no agonisteffects, which in addition, accelerates the proteasomal degradation of theestrogen receptor. The drug has poor oral bioavailability, and is administeredmonthly via intramuscular injection.
Applications:
Fulvestrant Acetate is a selective estrogen receptor degrader (SERD).It is indicated for the treatment of hormone receptor positivemetastatic breast in postmenopausal women with diseaseprogression following anti-estrogen therapy. Fulvestrant Acetate provides effective second-line therapy in metastaticor locally advanced breast for postmenopausal women who relapse orprogress after previous endocrine therapy. Four clinical trials in this setting showed similar efficacy to the otherhormonal agents (aromatase inhibitors and tamoxifen) with good tolerabilityprofile. Fulvestrant had a lower incidence of joint disorders. A Phase 2 clinical trial, sponsored by Atossa Genetics, is beingconducted by Dr. Sheldon Feldman, President of the The American Society ofBreast Surgeons, at Columbia University Breast Center in New York City on theuse of Fulvestrant Acetate administered through the microcatheterinto the lactiferous duct as neoadjuvant treatment forductal carcinoma in situand invasive breast .
