Alternate Title

Raloxifene in Preventing Breast Cancer in Premenopausal Women

Basic Trial Information

Objectives

1. Determine the safety and tolerability of raloxifene in premenopausal women at high risk of developing invasive breast cancer.
2. Determine the effect of raloxifene on blood steroid hormone levels (luteinizing hormone, estradiol, progesterone) and carotenoid levels during the menstrual cycle in these participants.
3. Determine the effect of raloxifene on the endometrium and ovaries in these participants.
4. Determine the effect of raloxifene on biochemical markers of bone metabolism, lipid profiles, and fibrinogen in these participants.
5. Determine the effect of raloxifene on health-related quality of life of these participants.
6. Determine the effect of raloxifene on bone mineral density in the spine and hip of these participants.

Outline

This is an open-label study.

Participants are medically evaluated, followed by an observation period of 1 to 2 menstrual cycles. After the observation period, participants receive oral raloxifene once daily for 2 years.

Quality of life is assessed 1 week prior to study drug administration and at 6, 12, 24 and 36 months after study drug administration.

Participants are followed for 1 year.
