Magnesium Oxide in Treating Hot Flashes in Menopausal Women With Cancer

June 17, 2016 updated by: Virginia Commonwealth University

A Pilot Phase II Trial of Magnesium Supplements to Reduce Menopausal Hot Flashes in Cancer Patients

RATIONALE: Magnesium oxide may help relieve hot flashes in women with cancer.

PURPOSE: This phase II trial is studying how well magnesium oxide works in treating hot flashes in menopausal women with cancer.

Study Overview

Detailed Description

OBJECTIVES:

Primary

  • To determine if magnesium oxide supplement will decrease the frequency and severity of hot flashes by 50% in menopausal women with cancer.

Secondary

  • To evaluate the effect of magnesium oxide on overall quality of life.
  • To evaluate the toxicities of magnesium oxide when administered at commonly used supplement doses.

OUTLINE: Patients receive oral magnesium oxide once daily in weeks 2-5. Patients whose hot flashes are not satisfactorily controlled after 2 weeks of treatment may receive magnesium oxide twice daily in weeks 4 and 5.

Patients complete a daily hot flash diary for 5 weeks beginning 1 week before treatment. Patients also complete quality-of-life, symptom, and self-assessment questionnaires at baseline, once weekly during treatment, and at the completion of treatment.

After completion of study treatment, patients are followed up for at least 30 days.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percent Difference in Hot Flash Activity (Score) Between Baseline and End of Treatment (Week 5)
Time Frame: from baseline to week 5
Hot flash score (frequency x severity) at baseline was compared to the end of treatment. The number of flashes in a 24 hour day and a score combining the number and severity of hot flashes (ie, 1 point for mild, 2 points for moderate, 3 points for severe and 4 points for very severe.
from baseline to week 5

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Difference in Quality of Life
Time Frame: from baseline to week 5
Mayo Clinic Uniscale instrument (6 questions with each question rating 0=as bad as it can be and 10=as good as it can be). A lower score is considered to be a better outcome.
from baseline to week 5
