Main objective
Scope: Efficacy, Safety, Therapy
In this active-controlled randomized trial two main primary objectives have been determined.
Firstly, the efficacy of the different treatment regimens will be assessed. The assessment will be based on PROMs and clinical evaluations such as vaginal pH and the vaginal maturation index, the latter a direct microscopic evaluation of the vaginal epithelium.
Secondly, safety of the different groups will be assessed. Although previous research already indicated no increased breast cancer recurrence, there is no direct comparative data available towards the different available treatment regimes. This will be tackled in this study. Evaluation will be done be measuring sex hormone concentrations systemically, which will be a surrogate for safety evaluation.
Secondary objectives 1
- The secondary objective in this study is the identification of microbial alterations after treatment initiation. Identification of these alterations can help in further understanding of the pathophysiology of vulvovaginal atrophy and potentially create opportunities for new treatment strategies towards vulvovaginal atrophy in breast cancer patients on endocrine therapy.

Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- The primary endpoint of this study is the efficacy of the implemented treatment regimes. Efficacy will be assessed based on patient-reported outcome measurements, being two validated questionnaires: EQ5D-questionnaire (Appendix 1) and the FACT-ES questionnaire (Appendix 2). This endpoint will be assessed at three time points: at start, after 6 weeks, and at the end (after 12 weeks).
Secondary endpoints 1
- The secondary endpoint is the safety of the implemented treatments. As a surrogate for safety, blood serum concentration of sex steroid hormones will be determined. This endpoint will be assessed at three time points: at start, after 6 weeks, and at the end (after 12 weeks).

- Reason
- Sponsor decision
- Explanation
- The manufacturer of Premeno Duo has updated the naming of the product to Premeno.
Additionally, due to amended laws and regulations, Premeno was reformulated.
This means the composition has changed slightly, the active ingredient Hyaluronic Acid has remained the same.
The loading has also been updated to 1 ovule daily for 14 days instead of daily for 10 days previously.
Due to this new dosage, a pack of Premeno will now contain 14 ovules instead of the 10 ovules. Since this study use this product according to the leaflet and standard use, the investigators want to adapt the duration of taking Premeno daily from 10 to 14 days.
These changes have a substantial impact in the study protocol and treatment of newly included subjects in the trial. Additionally, the dosing duration is also mentioned in de Informed Consent Forms and on the labeling.
For this reason, the study has been put on temporary halt and a substantial modification will be submitted to address the necessary changes to the study documentation. Upon authorisation of the substantial modification, a Restart of the Trial will be notified and inclusion will be started again. - Follow-up measures
- Currently, no patients are treated with Premeno. There is one patient in active treatment in one of the other treatment arms. This patient can remain in treatment. No new patients will be included in the trial until receipt of SM01 authorisation. After this, a Study restart will be notified within the legally binding timeframe.
- Benefit-risk balance changed
- No
- Treatment stopped
- No
