About this study

Official title: A Randomized, Placebo-Controlled, Double-Blind, Parallel, Phase 2 Study to Evaluate the Efficacy and Safety of RCN3028 in Treatment of Drug-Induced Moderate to Severe Vasomotor Symptoms in Breast Cancer Subjects

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.

Read the detailed description

Hot flashes are the most common symptom of menopause and affect almost 75% of menopausal women. Clinical evidence indicates potent antagonists of 5-HT2a are more likely to cause hypothermia. Risperidone is a potent 5-HT2a and a dopamine D2 receptor antagonist and is proposed to have effect on reduction of hot flashes through its dopaminergic and serotonergic antagonism.

Breast cancer is one of the most common cancers in women, according to the cancer registration report of the Ministry of Health and Welfare (MOHW), in 2014, up to 11,976 women suffered from breast cancer, which meant 33 women suffered from breast cancer daily. Recent epidemiology further disclosed that the incidence of breast cancer was top-ranked (70.74 per 100,000) among cancers of Taiwanese women in 2014.

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.

With recent advances of treatment modalities, more than 80% of women with a newly diagnosed breast cancer are expected to survive their disease for 5 years or more. One of the most common complaints was hot flashes induced by the treatment of breast cancer (i.e., tamoxifen induced hot flashes).

In general, hormone replacement therapy (HRT) is the most effective treatment for VMS (hot flashes). However, HRT has been associated with increased risk of recurrence in breast cancer survivors . Moreover, there is some evidence that HRT may not be as effective in women using tamoxifen. Therefore, a new therapy for treating hot flashes in breast cancer patients without increasing the risk of cancer recurrence is needed for such patient population, for example, a non-hormonal therapy. FDA approved low-dose paroxetine capsules (Brisdelle®) as a non-hormonal therapy for the treatment of moderate-to-severe vasomotor symptoms associated with menopause, despite the modest efficacy as compared with placebo, suicidal ideation and the drug-drug interactions (i.e., Brisdelle® and tamoxifen) . Brisdelle® itself is an antidepressant of selective serotonin reuptake inhibitors (SSRI) class. Several trials have recently demonstrated a role for SSRIs and serotonin-norepinephrine reuptake inhibitors (SNRIs) for the treatment of VMS.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: 4, 12 weeks

  2. 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.

    Measured: 4, 12 weeks

Secondary outcomes (8)
  1. Menopause Specific Quality of Life Questionnaire

    Menopause Specific Quality of Life Questionnaire will be completed at baseline, week 4, week 8 and week 12. Score on a scale Menopause Specific Quality of Life (MENQOL) questionnaire 0=not bothered at all - 6=extremely bothered. 4 domains, mean calculated for set of questions in each domain.

    Measured: 12 weeks

  2. The 50%, 75% and 100% responder rates

    Subject who had a reduction in the number of moderate and severe hot flashes of at least 50%, at least 75% and 100% from baseline.

    Measured: 12 weeks

  3. The time to onset of efficacy

    50% reduction in hot flashes for at least 3 consecutive days. The duration of first treatment used to first onset on efficacy will be calculated.

    Measured: 12 weeks

  4. Subject's and Physician's Global Assessment

    At the end of treatment Visit (week 12) each subject will provide an overall evaluation of study treatment by completing a Subject's Global Assessment. The rating scale for the final assessment by the subject includes: much worse, worse, unchanged, improved, much improved or free of symptoms. At week 12 each investigator will be asked to rate their subject's response to therapy using the same scale.

    Measured: 12 weeks

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

    Frequencies (number and percentage) of subjects with one or more treatment-emergent AEs (TEAEs) will be summarized by treatment arm, by the Medical Dictionary for Regulatory Activities (MedDRA) system with respect to System Organ Class (SOC) and preferred term.

    Measured: 12 weeks

  6. Change from baseline in weekly weighted severity score.

    calculated for each week as 2 times the number of moderate hot flashes plus 3 times the number of severe hot flashes plus 3 times the number of nighttime awakenings.

    The severity of VMS is defined as follows:

    1. Mild: sensation of heat without sweating;
    2. Moderate: sensation of heat with sweating, able to continue activity;
    3. Severe: sensation of heat with sweating, causing cessation of activity.
    4. Nighttime awakenings (i.e., episodes that wake the patient from sleep) associated with hot flashes are recorded separately and are considered severe.

    Measured: 12 weeks

  7. Change from baseline in the number of mild, moderate, and severe hot flashes.

    The weekly frequency will be calculated for each visit.

    Measured: 12 weeks

  8. Change from baseline in the number of nighttime awakenings because of hot flashes.

    The weekly frequency will be calculated for each visit.

    Measured: 12 weeks
