Evaluation of Homeopathic Treatment for Hot Flashes in Non Metastatic Breast Cancer (HBC)
Placebo-controlled Evaluation of the Homeopathic Drug BRN01 for the Treatment of Hot Flashes in Women With Non Metastatic Breast Cancer Treated by Adjuvant Hormonal Therapy
Study Overview
Detailed Description
Chemotherapy is used as an adjuvant treatment for breast cancer, like hormone therapy in patients with hormone-sensitive breast cancer or immunotherapy in those with Human Epidermal growth factor Receptor 2 (HER2)-overexpressing cancer.
These adjuvant treatments reduce the risk of recurrence and metastasis. The side effects of hormone therapy are known and depend on the therapeutic strategy and the drugs used. The side effects of Tamoxifen are similar to menopausal symptoms: hot flashes (half of the female population), vaginal dryness or leukorrhea, nausea, irregular menstruation, benign ovarian cyst and, less frequently, weight gain. Aromatase inhibitors have the same side effects, though with lesser frequency and intensity. The incidence rate of hot flashes after adjuvant treatment in menopausal women with localized breast cancer is 60 to 65 %, and these reactions are very severe in one third of these women. Despite this fact, the management of hot flashes is not systematic and there is currently no therapeutic strategy with proven efficiency. BRN01 (Boiron laboratory) is a homeopathic remedy whose active ingredient is already present in other homeopathic drugs indicated for the management of menopausal hot flashes. BRN01 could reduce the intensity of the reaction in women with breast cancer receiving adjuvant hormonal treatment.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: BRN01
A 2 to 4 weeks run-in period is planned, during which all patients receive single blinded "hot flash evaluation treatment" which is actually a placebo (2 tablets every morning and every evening during 2 to 4 weeks). At the end of this period, the hot flash score is calculated. If the score is ≥10, the patient can be randomized to one of the 2 arms:
|
2 tablets every morning and every evening during 8 to 10 weeks.
Each patient will receive 1 set of 5 treatment boxes (60 tablets/box).
|

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Evaluation of BRN01 efficacy in reducing hot flash score after 4 weeks of treatment
Time Frame: The patients are instructed to record the number and intensity of hot flashes in a self-evaluation booklet every day during the 2nd week of the first period (run-in period) and during the 4th week of the second period (placebo or BRN01).
|
The hot flash score is equal to: (number of hot flashes/day) x (mean intensity/day). Treatment efficiency scores will be calculated as follows: (hot flash score on the 4th week of the second period)-(hot flash score on the 2nd week of the first period). Then efficiency scores will be compared between the 2 arms (placebo versus BRN01). |
The patients are instructed to record the number and intensity of hot flashes in a self-evaluation booklet every day during the 2nd week of the first period (run-in period) and during the 4th week of the second period (placebo or BRN01).
