Clinical Trial Summary

To determine the efficacy in increasing sexual arousal, safety and tolerability of BZ371A in gel form applied to women with sexual arousal disorder.


Description:

FSAD is defined as the recurrent inability to attain or maintain sufficient genital arousal during sexual activity. Therefore, a healthy blood flow is central to the physiological processes related to sexual arousal, leading to genital lubrication, warmth, and clitoral protrusion. The vasculature and blood flow in vaginal tissue can be compromised due to natural aging and various risk factors, including cigarette smoking, alcohol abuse, lack of exercise, high-fat diets, hypertension, hypercholesterolemia, and diabetes mellitus. All these risk factors and conditions are highly prevalent among women and can lead to FSAD. BZ371A offers a potential solution by increasing blood flow in genital tissue through its unique mechanism of action, thereby restoring vascular homeostasis and the physiological processes related to sexual arousal in women.

Outcome

Type Measure Description Time frame Safety issue
Primary Efficacy in increasing arousal Evaluation of the efficacy of BZ371A in increasing arousal using Female Sexual Encounter Profile (FSEP) questionnaire. The study will evaluate number of "yes" answers to question 3 in the Female Sexual Encounter Profile (FSEP) questionnaire, divided by the number of valid attempts (question 7 of the FSEP).
The study will evaluate the increase in the FSEP score based on the baseline FSEP value, obtained before using the BZ371A. Thus, the higher the number of yes answers, the better the efficacy of the drug.
Baseline, 4 weeks and 8 weeks
Secondary Efficacy in increasing desire, lubrification, orgasm and arousal Evaluation of the success rate for desire, lubrification, orgasm and for arousal using Female Sexual Encounter Profile (FSEP). The number of successes for desire will be assessed using FSEP Question 2 / FSEP Question 7, for lubrication FSEP Question 4 / FSEP Question 7, for orgasm FSEP Question 5 / FSEP Question 7 and for the degree of arousal FSEP Question 6 / FSEP Question 7.
For each question, the number of "yes" answers will be counted as success. Therefore, for each "no" answer the value will be 0 and for each "yes" answer the value will be 1.
Baseline, 4 weeks and 8 weeks
Secondary Evaluation of the quality of female sexual encounters Evaluation based on the total score of the Female Sexual Encounter Profile (FSEP) questionnaire. The score ranges from 0 to 9. Therefore, the higher the score, the better the participant's sexual encounter. Baseline, 4 weeks and 8 weeks
Secondary Efficacy in increasing genital blood flow Evaluation of the efficacy of BZ371A in increasing genital blood flow using Cytocam system Baseline, 4 weeks (pre-dose, 15, 30, 60, 90, 120 and 240 minutes) and 8 weeks (pre-dose, 15, 30, 60, 90, 120 and 240 minutes)
Secondary Female Sexual Function Index (FSFI) Evaluation of the score for each domain (Desire, Arousal, Lubrication, Orgasm, Satisfaction, Pain) using the Female Sexual Function Index (FSFI) questionnaire. The score ranges from 2 to 36. Thus, the higher the score, the better the participant's sexual satisfaction. Baseline, 4 weeks and 8 weeks
Secondary Assessment of treatment satisfaction Response rate to the Global Assessment Question (GAQ), by the number of "yes" answers to the question about arousal and sexual pleasure. 4 weeks after baseline and 8 weeks after baseline
Secondary Adverse effects report Adverse effects evaluation of compound use and application 4 weeks after baseline, 8 weeks after baseline and, approximately, 11 weeks after baseline
Secondary Physical examination of the genitalia Number of participants with abnormal physical exam findings in the applied region. From up to 30 days before Baseline, Baseline, 4 weeks, 8 weeks and, approximately, 11 weeks
Secondary Change in systemic blood pressure Change in Diastolic Blood Pressure and Systolic Blood Pressure From up to 30 days before Baseline, Baseline, 4 weeks, 8 weeks and, approximately, 11 weeks
Secondary Change in Heart Rate (HR) Change in Heart Rate From up to 30 days before Baseline, Baseline, 4 weeks, 8 weeks and, approximately, 11 weeks
Secondary Basal chest electrocardiogram (ECG) Number of participants with abnormal electrocardiogram (ECG) findings. From up to 30 days before Baseline, 4 weeks after baseline, 8 weeks after baseline and, approximately, 11 weeks after baseline
Secondary Blood evaluation Number of participants with abnormal laboratory test results From up to 30 days before Baseline, 4 weeks after baseline and 8 weeks after baseline
Secondary Urine evaluation Number of participants with abnormal laboratory test results From up to 30 days before Baseline, 4 weeks after baseline and 8 weeks after baseline
