Brief Summary

This is an open-label, non-randomized pharmacokinetic study of fulvestrant in women scheduled for mastectomy or lumpectomy. Eligible subjects will be identified with breast cancer or DCIS. The first subject of each of five groups will receive fulvestrant intramuscularly. The subsequent 5 subjects of each group will receive fulvestrant by intraductal instillation. All subjects will be monitored for systemic and local adverse events during the procedure, and following the procedure until mastectomy or lumpectomy. Subjects that receive fulvestrant will undergo serial blood draws to determine fulvestrant blood concentration levels.

Detailed Description

This is an open-label, non-randomized pharmacokinetic study of pre-surgical fulvestrant in women scheduled for mastectomy or lumpectomy. Eligible subjects will be identified upon admission to the institution for surgical management of breast cancer or DCIS, specifically mastectomy or lumpectomy. There will be 5 groups, each consisting of 6 subjects. The first subject of each group will receive fulvestrant administered intramuscularly and the next 5 subjects will receive fulvestrant intraductally. Subjects where at least 1 suitable duct is identified may undergo nipple aspiration in order to facilitate duct identification and intraductal infusion of a fulvestrant accompanied by imaging (saline+ ultrasound). A maximum of 5 ducts will receive intraductal infusion of fulvestrant. Across all ducts, the total dose will not exceed 500 mg (10 mL). All subjects will be monitored for systemic and local adverse events during the procedure, immediately following the procedure, within 30 minutes, 1 hour, 4 hours and by phone following discharge on Days +1 and +2, +7, and pre-operative. Subsequent to mastectomy or lumpectomy, subjects will be assessed for systemic adverse events until discharge. Subjects that receive fulvestrant will undergo serial blood draws to determine fulvestrant blood concentration levels.

This study was terminated due to revised commercial analyses including a review of the potential to enroll in a timely manner the planned number of patients. This study was not terminated because of safety or efficacy concerns.
