Study Summary

This trial is testing whether the study drug Duavee can help treat symptoms of menopause and reduce the risk of developing breast cancer in women with a condition called ductal carcinoma in situ (DCIS).

Who is the study for?
Postmenopausal women aged 18-79 with newly diagnosed ER (+) DCIS of the breast, scheduled for surgery. Participants must be able to swallow pills, sign consent forms, and have normal organ/marrow function. Excluded are those on certain drugs, with invasive breast cancer or other serious conditions like blood clots or active second cancers.Check my eligibility
What is being tested?
The PROMISE Study tests if Duavee (conjugated estrogens/bazedoxifene), approved for menopause symptoms but not for DCIS in postmenopausal women, affects breast tissue markers and is safe. It includes a placebo group and examines quality-of-life impacts through questionnaires.See study design
What are the potential side effects?
Potential side effects may include hot flashes relief-related issues since Duavee is used to treat menopause symptoms. However, as its use in DCIS is experimental, there could be unknown risks which this study aims to uncover.

Experimental Treatment
Placebo Group
Group I: Arm I (conjugated estrogens/bazedoxifene)Experimental Treatment5 Interventions
Patients receive conjugated estrogens/bazedoxifene orally (PO) once daily (QD) for 28 +/- 7 days in the absence of disease progression or unacceptable toxicity. Patients then undergo surgery.
Group II: Arm II (placebo)Placebo Group5 Interventions
Patients receive placebo PO QD for 28 +/- 7 days in the absence of disease progression or unacceptable toxicity. Patients then undergo surgery.
