Treatment and study plan

Hyalo Gyn gel in prefilled applicators

Device

One vaginal application of Hyalo Gyn gel every 3 days to a total of 12 consecutive weeks.

Primary outcomes

  1. Change of patient's perception of vulvovaginal dryness

    Time frame: From baseline to 12 weeks of treatment

    Change of patient's perception of vulvovaginal dryness associated with vulvovaginal atrophy in postmenopausal women in Hyalo Gyn gel group compared to no-treatment group. The vulvovaginal dryness was reported on a four-point scale (0=absent, 1=mild, 2=moderate, 3=severe).

Secondary outcomes

  1. Change of patient's perception of vulvovaginal dryness

    Time frame: From baseline to 4 weeks of treatment

    Change of patient's perception of vulvovaginal dryness associated with vulvovaginal atrophy in postmenopausal women in Hyalo Gyn gel group compared to no-treatment group. The vulvovaginal dryness was reported on a four-point scale (0=absent, 1=mild, 2=moderate, 3=severe).

  2. Change of patient's perception of vulvovaginal symptoms

    Time frame: From baseline to 4 and 12 weeks of treatment

    Change of patient's perception of symptoms associated with vulvovaginal atrophy in postmenopausal women in Hyalo Gyn gel group compared to no-treatment group. Each symptom (dryness, irritation/itching, soreness, dysuria, dyspareunia) will be reported on a four-point scale (0=absent, 1=mild, 2=moderate, 3=severe)

  3. Change of the average score of Vaginal Health Index (VHI)

    Time frame: From baseline to 4 and 12 weeks of treatment

    Change of VHI in postmenopausal women in Hyalo Gyn gel group compared to no-treatment group. VHI will be calculated on the basis of vaginal elasticity, vaginal fluid volume, vaginal pH, vaginal mucosa epithelial integrity, and vaginal moisture on a scale ranging from 1 (poorest) to 5 (best). VHI assigned score is the sum of subscores and ranges from 5 to 25. A lower score corresponds to a greater atrophy.

  4. Change of vaginal pH

    Time frame: From baseline to 4 and 12 weeks of treatment

    Change of vaginal pH in postmenopausal women in Hyalo Gyn gel group compared to no-treatment group. The pH values are grouped on a four-point scale and scored respectively: pH lower than 5 = 0; pH between 5 and 5.49 = 1; pH between 5.5 and 6.49 = 2; pH higher than 6.49 =3.

  5. Improvement of sexual function through questionnaire Female Sexual Function Index (FSFI)

    Time frame: From baseline to 4 and 12 weeks of treatment

    Improvement of sexual function in postmenopausal women in Hyalo Gyn gel group compared to no-treatment group. Female Sexual Function Index (FSFI) questionnaire consists of six domains - desire (two items), arousal (four items), lubrication (four items), orgasm (three items), satisfaction (three items), and pain (three items) - answered on a five-point Likert scale (0, no sexual activity; 1, never/very low; 5, always/very high). A score is calculated for each of the six domains, and the total score is obtained by summing all of the items. Total score ranges from 2 to 36. A lower score corresponds to a greater sexual dysfunction.

  6. Improvement of sexual function through questionnaire Female Sexual Distress Scale-Revised (FSDS-R)

    Time frame: From baseline to 4 and 12 weeks of treatment

    Improvement of sexual function in postmenopausal women in Hyalo Gyn gel group compared to no-treatment group. Female Sexual Distress Scale-Revised (FSDS-R) questionnaire consists of 13 items scored on a five-point scale (0, never; 1, rarely; 2, occasionally; 2, frequently; 4, always). The total score is obtained by summing all of the items. Total score ranges from 0 to 52. A higher score corresponds to a greater sexual dysfunction.

  7. Amelioration of the vaginal maturation (VM) index

    Time frame: From baseline to 12 weeks of treatment

    Amelioration of VMI in postmenopausal women in Hyalo Gyn gel group compared to no-treatment group. Vaginal maturation (VM) index is calculated quantifying the percentages of parabasal, intermediate, and superficial cells. The following formula is used: VMI = [1(% superficial cells)] + [0.6(% intermediate cells)] + [0.2(% parabasal cells)]. The index ranges from 0% to 100%.The higher the maturation index, the higher the number of mature cells (0%-49%, low stimulation of the vaginal epithelium; 50%-64%, moderate stimulation of the vaginal epithelium; 65%-100%, high stimulation of the vaginal epithelium).

  8. Patient's global assessment of overall satisfaction

    Time frame: 4 and 12 weeks of treatment

    Patient's global assessment of overall satisfaction in postmenopausal women in Hyalo Gyn gel group compared to no-treatment group.Patient's global assessment (PTGA) is evaluated as the patient's overall satisfaction of the treatment scored on a four grade scale, ranging from 0 to 3 (0= dissatisfied or very dissatisfied, 1= moderately satisfied or satisfied, 2= very satisfied and 3= greatly satisfied). A higher score corresponds to a greater satisfaction.

  9. Ease in the method of Hyalo Gyn gel administration

    Time frame: 4 and 12 weeks of treatment

    Ease in the method of Hyalo Gyn gel administration will be reported by the patients as excellent, good, acceptable, bad or unacceptable

  10. Local tolerability at the application site

    Time frame: 4 and 12 weeks of treatment

    Local tolerability of Hyalo Gyn gel at the application site will be evaluated by both the clinician and the patient through a 5-point scale: 5 = excellent (no reaction), 4 = good (small reaction that spontaneously resolves), 3 = moderate (reaction tolerated with difficulty by the subject), 2 = poor (reaction needing interruption of treatment), 1 = bad (serious reaction)

  11. Safety of the treatment: Collection of adverse events

    Time frame: 4 and 12 weeks of treatment

    Collection of adverse events emerged as consequence of the product application and any other adverse event occurred during the study
