Efficacy and Safety of Non-hormonal Vaginal Preparations in Treating Vaginal Dryness

Vulvovaginal irritation due to dryness is a frequent complaint among post- and some premenopausal women. International guidelines recommend non-hormonal products as first line therapy.

Efficacy and safety of the medical device Vagisan® Moisturising Cream (VMC), a non-hormonal vaginal cream for the treatment of vulvovaginal dryness and Gynomunal Vaginal Gel (GVG), a non-hormonal gel should be compared in a 12-week multicentre, open-label, randomised, two-period cross-over phase III trial. The hypothesis was that VMC is non-inferior to GVG.

The primary endpoint was the sum of subjective symptoms of vulvovaginal atrophy (VVA) added up over each treatment period. Furthermore, objective symptoms of VVA and adverse effects were planned to be assessed. 120 women should be randomly allocated to either of the two treatments, each given over a period of 4 weeks.

About this study

The purpose of the study was to test the non-inferiority of the medical device Vagisan® Moisturising Cream (VMC) in comparison to Gynomunal® vaginal gel (GVG) in 6 centres in 120 women who suffered from "vaginal dryness". The main objective criterion was to compare the sum of 4 subjective symptoms of "vaginal dryness" measured daily over a period of 28 days. VMC should be applied daily, while GVG had to be administered daily during the first week and twice weekly thereafter.

The main objective parameter for efficacy analysis was the sum of the subjective symptoms of vaginal dryness (feeling of dryness, itching, burning sensation and pain) before, during (patient diaries) and after the 28-day therapy period.

The per-protocol analysis and of the intent-to-treat analysis should prove non-inferiority of VMC compared to GVG, despite a possible carry-over effect to the detriment of VMC. To avoid the problem of any possible carry-over effect the analysis of the first period was chosen for the primary comparison of both products.

Furthermore, objective symptoms of vaginal dryness detected via colposcopy, the vaginal secretion's pH, the efficacy assessment by the patients and the treating doctor and patients' questionnaires with regard to the product characteristics of the medical devices should be evaluated.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Women over the age of 18.
  • Women with vaginal dryness who do not want to or are not allowed to use oestrogens, such as post-menopausal women, women with oestrogen-dependent tumours in their medical history and women who had been treated with systemic medicinal products that can have a drying-out effect on the vaginal mucous membranes.
  • Total score (0-16) of at least 3 of four subjective symptoms (feeling of dryness, itching, burning sensation and pain).
  • Written declaration of consent for the voluntary participation in the study is present.

Exclusion criteria

  • Known hypersensitivity to one of the ingredients of the test and/or reference medical device.
  • Current vaginal infections.
  • Recurring (i.e. at least 3) vaginal infections within the last 12 months.
  • Additional (not study-related) treatment of vaginal dryness during the therapy phases.
  • Therapy with antibiotics, steroids (excluding sexual steroids in oral, dermal or transdermal application) or antimycotics in the last 14 days before inclusion and participation in this study.
  • Women who are not able to participate properly in this study.
  • Fertile women without sufficient contraceptive protection.
  • Fertile women who are pregnant (positive HCG test) or breastfeeding.
  • Current alcohol and/or drug abuse.
  • Participation in another clinical study within the last four weeks and/or parallel participation in this study.

Treatment and study plan

Vagisan® Moisturising Cream

Device

Once in the evenings before going to bed, intravaginally with the help of the applicator included (approximately 2.5 g per application) and perivaginally one fingertip unit (approximately 0.5 g per application).

Other names: WO 2085

Gynomunal® vaginal gel

Device

Once in the evenings before going to bed, intravaginally with the help of the applicator included (approximately 2.5 g per application) and perivaginally one fingertip unit (approximately 0.5 g per application).

Primary outcomes

  1. per patient intraindividually determined total score consisting of the patients' subjective symptoms (feeling of dryness, itching, burning sensation and pain)

    Time frame: Therapy period of 28 days

    The main objective criterion for the confirmatory analysis was the per patient intraindividually determined total score consisting of the patients' subjective symptoms (feeling of dryness, itching, burning sensation and pain, each rated as 0=not present, 1=hardly pronounced, 2=moderately pronounced, 3=quite pronounced, 4=very pronounced) during the course of therapy. This was based on the daily entry in the patient diary.

Secondary outcomes

  1. Intraindividually determined total score consisting of the evaluations of the objective "vaginal dryness" diagnoses

    Time frame: 28 days

    • Descriptive account of the per patient intraindividually determined total score consisting of the evaluations of the objective "vaginal dryness" diagnoses made by the investigator during the visits (thinning of the epithelium, redness, petechial bleeding, discharge, each rated as 0=not present, 1=hardly pronounced, 2=moderately pronounced, 3=quite pronounced, 4=very pronounced).

  2. Patients' individual subjective symptoms of "vaginal dryness"

    Time frame: 28 days

    Descriptive account of the patients' individual subjective symptoms of "vaginal dryness" expressed during the visits (feeling of dryness, itching, burning sensation and pain).

  3. Overall efficacy and tolerability assessments

    Time frame: 28 days

    The overall efficacy and tolerability assessments (investigator and/or patient) with the ratings "very good", "good", "satisfactory" and "poor".

  4. Occurrence of side effects

    Time frame: 28 days

    The assessment of one-sided 95% confidence intervals for the occurrence of side effects when using the test and reference medical device

  5. Assessment of adverse events

    Time frame: 28 days

    The assessment of adverse events that have not been classified as related to the medical device.

  6. Vaginal pH

    Time frame: 28 days

    Descriptive account of the vaginal pH as determined by the investigator during the visits.

  7. Patients' subjective satisfaction with the test and reference medical device

    Time frame: 28 days

    The patients' subjective satisfaction with the test and reference medical device based on a patient questionnaire conducted at the end of each treatment period [feeling of skin (within approximately 10 minutes of application and the following morning), discharge the next morning, stickiness, spreadability on the vulva (perivaginal), cooling effect, softness of the medical device, fragrance, handling of the applicator, overall assessment by the sexual partner] with ratings from 1 (very positive) to 6 (very negative) or 0=no assessment (see chapter 9.1.6 "Patient questionnaire").
