Primary Outcome Measures:
  • 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). ] [ Designated as safety issue: No ]

    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).



Secondary Outcome Measures:
  • Evaluation of BRN01 efficacy in reducing the hot flash score after 8 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 8th week of the second period (placebo or BRN01). ] [ Designated as safety issue: No ]

    Treatment efficacy scores will be calculated as follows: (hot flash score on the 8th 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).


  • Evaluation of the mean daily intensity of hot flashes during the run-in period and on the 4th and 8th weeks of treatment in both arms. [ Time Frame: The patients are instructed to record the intensity of hot flashes in a self-evaluation booklet, daily, during the 2nd week of the first period (run-in period), and during the 4th and 8th weeks of the second period (placebo or BRN01). ] [ Designated as safety issue: No ]
  • Evaluation of the mean daily frequency of hot flashes during the run-in period and on the 4th and 8th weeks of treatment in both arms. [ Time Frame: The patients are instructed to record the number of hot flashes in a self-evaluation booklet, daily, during the 2nd week of the first period (run-in period), and during the 4th and 8th weeks of the second period (placebo or BRN01). ] [ Designated as safety issue: No ]
  • Evaluation of quality of life in both arms [ Time Frame: The patients are instructed to complete quality of life items on the 7th day of each evaluation period (2nd week of the run-in period, 4th and 8th weeks of the second period) ] [ Designated as safety issue: No ]
  • Evaluation of patient satisfaction with the treatment and with the management of hot flashes. [ Time Frame: The patients are instructed to record all new hot flash treatments started, as well as their satisfaction with their management, on the 7th day of each evaluation period (2nd week of the run-in period, 4th and 8th weeks of the second period). ] [ Designated as safety issue: No ]
  • Evaluation of treatment tolerance [ Time Frame: Side effects are registered by the oncologist at each visit (planned during the 3rd week or the 4th week of the run-in period and during the 9th week or the 10th week of the second period) ] [ Designated as safety issue: No ]
  • Evaluation of patient compliance [ Time Frame: The number of remaining tablets will be counted at each visit (planned during the 3rd week or the 4th week of the run-in period and during the 9th week or the 10th week of the second period) ] [ Designated as safety issue: No ]

Arms Assigned Interventions
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:

  • Experimental: BRN01
  • Placebo Comparator: Placebo
Drug: BRN01
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).
Placebo Comparator: Placebo

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:

  • Experimental: BRN01
  • Placebo Comparator: Placebo
Drug: Placebo
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).

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.
