Overview

Generic Name(s):
fulvestrant
Trade Name(s):
Faslodex
NCI Definition [1]:
A synthetic estrogen receptor antagonist. Unlike tamoxifen (which has partial agonist effects) and the aromatase inhibitors (which reduce the estrogen available to tumor cells), fulvestrant binds competitively to estrogen receptors in breast cancer cells, resulting in estrogen receptor deformation and decreased estrogen binding. In vitro studies indicate that fulvestrant reversibly inhibits the growth of tamoxifen-resistant, estrogen-sensitive, human breast cancer cell lines. (NCI04)

Biomarker-Directed Therapies

Fulvestrant has been investigated in 128 clinical trials, of which 95 are open and 33 are closed. Of the trials investigating fulvestrant, 1 is early phase 1 (1 open), 31 are phase 1 (25 open), 11 are phase 1/phase 2 (7 open), 63 are phase 2 (45 open), 1 is phase 2/phase 3 (1 open), 19 are phase 3 (16 open), 1 is phase 4 (0 open), and 1 is no phase specified (0 open).

ER Positive, HER2 Negative, and HER2 Deficient Expression are the most frequent biomarker inclusion criteria for fulvestrant clinical trials.

Breast carcinoma, invasive breast carcinoma, and breast adenocarcinoma are the most common diseases being investigated in fulvestrant clinical trials [2].
