45 studies on the registry are indexed under Atrophic Vaginitis; 7 are open to participants now.
This study's enrollment of 255 is above the median of 69 across 40 interventional studies indexed under Atrophic Vaginitis.

Main Inclusion Criteria:
Main Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Change From Baseline to Week 12 in Percentage of Parabasal Cells in the Maturation Index of the Vaginal Smear
The percentage of parabasal cell was determined from the vaginal smears collected during the study. A 100-cell count was performed by a central laboratory to classify cells as parabasal (P) (including the basal), intermediate (I), and superficial (S) squamous cell types. Data obtained at Baseline and Week 12 as well as the change from Baseline to Week 12 are presented.
Time frame: Baseline and Week 12
Change From Baseline to Week 12 in Percentage of Superficial Cells in the Maturation Index of the Vaginal Smear
The percentage of superficial cell was determined from the vaginal smears collected during the study. A 100-cell count was performed by a central laboratory to classify cells as parabasal (P) (including the basal), intermediate (I), and superficial (S) squamous cell types. Data obtained at Baseline and Week 12 as well as the change from Baseline to Week 12 are presented.
Time frame: Baseline and Week 12
Change From Baseline to Week 12 in Vaginal pH
A pH strip fixed on an Ayre spatula (or equivalent) was applied directly to the lateral wall of the vagina. The change in color of the pH indicator strip was compared to the color chart for pH evaluation. The corresponding pH value (with one decimal) was recorded. Data obtained at Baseline and Week 12 as well as the change from Baseline to Week 12 are presented.
Time frame: Baseline and Week 12
Change From Baseline to Week 12 in Severity of the Most Bothersome Symptom of Dyspareunia
The severity of dyspareunia was evaluated by a questionnaire filled out by women.
