What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of TSS (Total severity score) for subjective symptoms of atrophy | The severity of each of the subjective symptoms dryness, itching, burning and pain unrelated to sexual intercourse will be assessed according to the following scale: 0=none, 1=mild, 2=moderate, 3=severe, 4=very severe The total severity score will be calculated as the sum score of the subjective symptoms resulting in a minimum score of 0 (best) and a maximal score of 16 (worst). | From baseline to visit 3 (day 38) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of TSS (Total severity score) for subjective symptoms of atrophy | The severity of each of the subjective symptoms dryness, itching, burning and pain unrelated to sexual intercourse will be assessed according to the following scale: 0=none, 1=mild, 2=moderate, 3=severe, 4=very severe The total severity score will be calculated as the sum score of the subjective symptoms resulting in a minimum score of 0 (best) and a maximal score of 16 (worst). | From baseline to visit 2 (day 8), visit 2 (day 8) to visit 3 (day 38) and visit 3 (day 38) to visit 4 (day 44) | 
| Change of severity scoring for each of the subjective symptoms (dryness, itching, burning and pain unrelated to sexual intercourse) | The severity of each of the subjective symptoms dryness, itching, burning and pain unrelated to sexual intercourse will be assessed according to the following scale: 0=none, 1=mild, 2=moderate, 3=severe, 4=very severe | From baseline to visit 2 (day 8) and visit 3 (day 38), visit 2 (day 8) to visit 3 (day 38) and visit 3 (day 38) to visit 4 (day 44) | 
| Change of each DIVA domain score (A - D) and change of total DIVA score (excluding questions 12 to 15) | The DIVA questionnaire addresses the impact of vaginal symptoms such as vaginal dryness, soreness, irritation and itching on the day-to-day life regarding the patient's activities, relationships, and feelings by any of these symptoms (Huang, 2015; Gabes, 2021). | From baseline to visit 3 (day 38) | 
| Change of each DIVA domain score (A - D) and change of total DIVA score in the subgroup of sexually active women with dyspareunia | The DIVA questionnaire addresses the impact of vaginal symptoms such as vaginal dryness, soreness, irritation and itching on the day-to-day life regarding the patient's activities, relationships, and feelings by any of these symptoms (Huang, 2015; Gabes, 2021). | From baseline to visit 3 (day 38) | 
| Change of each single parameter and of sum score over objective assessment of VHI | The objective status of the vagina will be assessed by the Investigator according to the Vaginal Health Index (Bachmann, 1995). Each of the five criteria - elasticity, fluid secretion, pH, epithelial mucosa and moisture - will be graded from 1 (worst) to 5 (best) and will then be summed up, so that the minimum score will be 5 (worst) and the maximum score will be 25 (best) | From baseline to visit 3 (day 38) | 
| Change of vaginal pH |  | From baseline to visit 3 (day 38) | 
| Patient questionnaire |  | Day 3, visit 3 (day 38), visit 4 (day 44) | 
| Change of severity scoring for dyspareunia for the subgroup of sexually active women with dyspareunia | Severity scoring for Dyspareunia will be assessed by the patients according to the following scale: 0=none,1=mild, 2=moderate, 3=severe, 4=very severe | From baseline to visit 2 (day 8) and visit 3 (day 38), visit 2 (day 8) to visit 3 (day 38) and visit 3 (day 38) to visit 4 (day 44) | 
| Change of impairment of daily life due to dyspareunia (VAS) for the subgroup of sexually active women with dyspareunia | Impairment of daily life due to dyspareunia will be assessed using a 10 cm visual analogue scale (VAS) ranging from 0 (no impairment) to 10 (very pronounced impairment). | From baseline to visit 2 (day 8) and visit 3 (day 38), visit 2 (day 8) to visit 3 (day 38) and visit 3 (day 38) to visit 4 (day 44) | 
| Global judgement of efficacy by the investigator | The global judgement of efficacy will be assessed according to the following scale: 1=very good, 2=good, 3=moderate, 4=poor | On visit 3 (day 38) | 
| Global judgement of efficacy by the patient | The global judgement of efficacy will be assessed according to the following scale: 1=very good,2=good, 3=moderate, 4=poor | On visit 3 (day 38) | 
| Global judgement of tolerability by the investigator | The global judgement of tolerability will be assessed according to the following scale: 1=very good, 2=good, 3=moderate, 4=poor | On visit 3 (day 38) | 
| Global judgement of tolerability by the patient | The global judgement of tolerability will be assessed according to the following scale: 1=very good, 2=good, 3=moderate,4=poor | On visit 3 (day 38) | 
| Participants with premature trial termination due to adverse device effects, adverse events, concomitant medication |  | From baseline to visit 4 (day 44) |
