NCT06161792

Brief Summary

Due to the fact that majority of breast cancers are estrogen-receptor and/or progesterone receptor positive, tamoxifen and aromatase inhibitors (AIs) are among the mainstay therapies to treat breast cancer. Prior clinical studies of tamoxifen suggested that up to 80 % of patients experienced hot flashes during therapy with tamoxifen, and 30 % defined their symptoms as severe. Despite the high efficacy of tamoxifen, the harmful side effects have been identified in previous studies as a significant reason for not persisting with the treatment in 16 - 30 % of breast cancer patients. The primary purpose of this study is to determine if RCN3028 is effective and safe in the treatment of moderate to severe vasomotor symptoms associated. In accordance with the latest FDA guidance study participants will have a minimum of 7 moderate to sever hot flashes per day, or 50 per week at baseline.

Outcome Measures

Primary Outcomes (2)

  • Mean change in frequency of moderate to severe VMS

    Mean change in frequency numbers of moderate to severe VMS(Vasomotor Symptoms) from baseline to weeks 4 and week 12. The VMS episode event log recorded the frequency of hot flashes per day, such mild, moderate, severe, nighttime awakening number.

    4, 12 weeks

  • Mean change in severity of moderate to severe VMS

    Mean change in severity score of moderate to severe VMS from baseline to weeks 4 and week 12. The severity score for VMS for each subject is calculated as the sum of 2 times the number of moderate VMS, plus 3 times the number of severe VMS, divided by the total number of moderate and severe VMS.

    4, 12 weeks

Secondary Outcomes (8)

  • Menopause Specific Quality of Life Questionnaire

    12 weeks

  • The 50%, 75% and 100% responder rates

    12 weeks

  • The time to onset of efficacy

    12 weeks

  • Subject's and Physician's Global Assessment

    12 weeks

  • Frequencies(number and percentage) of subjects with treatment-emergent AEs (TEAEs)
