Eligibility criteria
Principal inclusion / exclusion criteria as submitted by sponsor
Inclusion criteria 10
- Women, of any race or ethnicity, who are ≥18 years of age at the time of Screening 1.
- Able to understand the trial and willing to comply with trial requirements.
- Has provided written informed consent.
- Clinical diagnosis of VLS made by either a dermatologist or a gynaecologist familiar with VLS.
- Presence of at least one of the following signs of VLS: a. Hyperkeratosis (i.e., patches/plaques of bright white skin with a ‘powdery’ texture) and/or b. Sclerosis (i.e., areas of yellowish/ivory white skin with a smooth/waxy/firm texture. Sclerosis is often seen at the tips of the labia minora, or on periclitoral or perineal skin) in at least one of the following vulvar areas: Clitoris and/or periclitoral skin (C); Right interlabial sulcus and labium minus (R); Left interlabial sulcus and labium minus (L); Posterior Fourchette and/or perineum (P)
- First symptoms of VLS (e.g., itching and/or pain) noticed by the patient at least 6 months before baseline.
- At least four WI-NRS scores available in the diary for calculation of the average WI-NRS at the baseline visit.
- At least moderate itch defined as average WI-NRS ≥4 at the Baseline visit (average WI-NRS is calculated as the average of all available and at least four WI-NRS scores which are to be reported once daily by the patient in the diary for 7 days prior to the Baseline visit
- Women must be of either: a) Non-childbearing potential, i.e., post-menopausal* or confirmed sterile (e.g., hysterectomy, bilateral salpingectomy or bilateral oophorectomy) (*Note: a postmenopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy. However, in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient) OR, b) Childbearing potential with a negative highly sensitive* urine pregnancy test at the Baseline visit (*Note: a highly sensitive urine pregnancy test must have a sensitivity down to at least 25 mIU/ml for human chorionic gonadotropin (hCG)).
- Women of childbearing potential must agree to use a highly effective method of contraception (i.e., a method with a failure rate of less than 1 % per year when used consistently and correctly) while receiving double-blind treatment.
Exclusion criteria 17
- Pregnant, breast feeding, or planning to become pregnant during the trial.
- Any (other than VLS) ongoing localised or systemic disease involving the vulvar region – e.g., lichen planus, psoriasis, eczema, ulcerative colitis or known active infection (bacterial, viral or fungal).
- Ongoing symptomatic Urinary Tract Infection (UTI).
- Ongoing or prior diagnosis of any genitoanal malignancy or pre-malignancy
- Any kind of ongoing cancer (or anti-cancer treatment within 3 months or 5 half-lives (whichever is longest) prior to the Baseline visit).
- Any chronic or acute systemic medical condition that, in the opinion of the investigator, may pose a risk to the safety of the patient or may interfere with the assessment of efficacy in this trial.
- Known history of allergic reaction to any ingredients in MC2-25 cream or MC2-25 vehicle
- Start of a new or change of existing non-biologic systemic treatment, including but not limited to corticosteroids, cyclosporin, methotrexate and tacrolimus, within 21 days prior to the Baseline visit.
- Start of a new or change of existing biologic systemic treatment, including but not limited to etanercept, adalimumab, alefacept, infliximab, and ustekinumab within 3 months or 5 half-lives (whichever is longest) prior to the Baseline visit.
- Start of a new or change of existing systemic or intravaginal treatment with estrogen containing products, within 21 days prior to the Baseline visit
- Start of new or change of menstrual care routines within 21 days prior to the Baseline visit.
- Use of emollients (including but not limited to creams, ointments, oils, or soaps with emollient properties) on the vulvar region within 3 days prior to the Baseline visit.
- Use of any topical treatment on the vulvar region, including but not limited to calcineurin inhibitors, corticosteroids or anti-infectives within 14 days prior to the Baseline visit.
- Use of any light therapy on the vulvar region, including but not limited to UV-B, UV-A, and laser, within 28 days prior to the Baseline visit.
- Received a non-marketed or blinded drug within 28 days or 5 half-lives (whichever is longer) prior to the Baseline visit.
- If in the opinion of the investigator, the patient is unlikely to comply with the clinical trial protocol.
- Previously randomised in this trial.
