Clinical Trial Summary

RATIONALE: Magnesium oxide may help relieve hot flashes symptoms in women with a history of breast cancer.

PURPOSE: This randomized clinical trial studies how well a high-dose or a low-dose of magnesium oxide works compared to placebo in treating menopausal women with hot flashes and a history of breast cancer.

Description:

OBJECTIVES:

Primary

• Evaluate the efficacy of magnesium oxide on hot flashes in women with a history of breast cancer.

Secondary

• Evaluate the side-effect profile of magnesium oxide in this study population.

• Evaluate the effect of magnesium oxide on the secondary outcomes hot flash frequencies, hot flash severities, toxicities (including diarrhea), and hot flash-related daily interference on activities.

• Evaluate the effect of magnesium oxide on the change of magnesium level (for the first 150 patients).

OUTLINE: This is a multicenter study. Patients are stratified according to age (18-49 years vs ≥ 50 years), current tamoxifen and/or selective estrogen receptor modulator (yes vs no), current aromatase inhibitor (yes vs no), and daily frequency of hot flashes (4-9 vs ≥ 10). Patients are randomized to 1 of 4 treatment arms.

• Arm I: Patients receive a low-dose of magnesium oxide orally (PO) daily (QD).

• Arm II: Patients receive a high-dose of magnesium oxide PO QD.

• Arm III: Patients receive a low-dose of placebo PO QD.

• Arm IV: Patients receive a high-dose of placebo PO QD. In all arms, treatment continues for 8 weeks in the absence of unacceptable toxicity.

Some patients may continue or crossover to receive magnesium for 4 more weeks.

Patients complete the Hot Flash Diary daily for 9 weeks beginning 1 week before treatment. They also complete the Symptom Experience Questionnaire, the Profile of Mood States (POMS), and Hot Flash-Related Daily Interference Scale (HFRDIS) questionnaires periodically during study treatment.

Patients undergo blood sample collection at baseline and at the end of weeks 5 and 9 for serum magnesium level analysis.

Eligibility

DISEASE CHARACTERISTICS:

• Women with a history of breast cancer (currently without malignant disease)

• Bothersome hot flashes (defined by their occurrence = 28 times per week and of sufficient severity to make the patient desire therapeutic intervention)

• Presence of hot flashes for = 30 days prior to study registration

• Willingness to provide the biologic specimens as required by the protocol

• Hormone receptor status not specified

PATIENT CHARACTERISTICS:

• Women who are postmenopausal as defined by absence of a period in the past 12 months or bilateral oophorectomy

• Women with at least one ovary but without a uterus should be deemed postmenopausal by either age over 55 or a combination of estrogen within a postmenopausal range (per local lab) and FSH over 40 mIU/mL

• Ability to complete questionnaire(s) by themselves or with assistance

• ECOG performance status 0 or 1

• No history of allergic or other adverse reaction to magnesium

• No diabetes

• No patients with conditions that are implicated in decreased absorption of magnesium (e.g., Crohn disease, ETOH abuse)

• No patients who have diarrhea where magnesium might make it worse (per provider discretion)

PRIOR CONCURRENT THERAPY:

• None of the following current (= 28 days prior to registration) or planned therapies (tamoxifen, raloxifene, or aromatase inhibitors are allowed, but the patient must have been on a constant dose for = 28 days and must not be expected to stop the medication during the study period):

• Antineoplastic chemotherapy (trastuzumab or lapatinib are allowed)

• Androgens

• Estrogens (any delivery route)

• Progestational agents

• No prior use of magnesium for hot flashes

• No current or planned use of gabapentin (for any reasons) or antidepressants (for any reasons) or other agents for treating hot flashes (except stable dose of vitamin E is allowed as long as it was started > 30 days prior to study registration and are to be continued through the study period; soy is allowed, if it is planned to be continued at the same dose during the study period)

• No current use of magnesium for any indication (except one standard multiple vitamin dose is allowed per day)

• Not taking diuretics, corticosteroids, bile acid sequestrants, and other prescription and over-the-counter medications that may affect magnesium levels

• No current (= 7 days prior to registration) or planned use of other non-drug therapies for managing hot flashes, such as acupuncture or yoga (use of these therapies for other reasons is allowed)
