简要总结
This is a randomized, double-blind, placebo-controlled, two-arm parallel-group clinical study evaluating the efficacy and safety of INTIMIQUE OVULI, a Class IIa vaginal medical device, in adult women (18-60 years) diagnosed with bacterial vaginosis (BV) or vulvovaginal candidiasis (VVC). Participants are randomized 1:1 to receive the active device or a placebo ovule, in addition to standard-of-care antibacterial or antifungal pharmacological treatment, depending on diagnosis. Treatment is administered in three cycles (7 consecutive days, then 4 consecutive days, then 3 consecutive days, each separated by washout periods), followed by a 2-month follow-up. The study is a post-market clinical investigation conducted as part of the device's transition from MDD to MDR.
详细描述
INTIMIQUE OVULI is a Class IIa vaginal medical device supplied as vaginal ovules (7 ovules per pack, 2 g each), intended as an adjuvant in the prophylaxis, and prevention of vaginal infections and their recurrence (fungal vaginitis and bacterial vaginosis), and for vaginal environment alterations. Each ovule contains tyndallized Lactobacillus rhamnosus LRH020, sodium hyaluronate, lactic acid, essential oils (Melaleuca alternifolia and white thyme), galactoarabinan, vitamin E acetate, vitamin A palmitate, and semisynthetic triglycerides. The device is intended to restore the vaginal environment and physiological pH, counteract vaginal dryness, and protect the mucosa, reducing irritative symptoms (itching, redness, burning, edema, pain).
Device safety has been previously assessed through preclinical testing: an in vitro cytotoxicity test (NRU assay, ISO 10993-5), a skin sensitization test (Local Lymph Node Assay in mice, ISO 10993-10/OECD TG 429), and a vaginal irritation test in rabbits (ISO 10993-10), all with favorable (non-cytotoxic, non-sensitizing, non-irritant) results.
Clinical diagnosis of BV or VVC will be established at the screening visit based on clinical history, vaginal pH, and characteristics of vaginal discharge, with microbiological confirmation by vaginal swab for VVC. Treatment duration is 7 consecutive days (T-7d), followed by a 3-week washout, a second 4-day treatment, a further washout of 3 weeks and 3 days, a third 3-day treatment, and a 2-month follow-up period (T-112d). Efficacy will be assessed in the overall population and, post-hoc, in the two diagnostic subgroups (BV and VVC).

研究组 & 干预措施
INTIMIQUE OVULI
Participants receive INTIMIQUE OVULI vaginal ovules administered according to the three treatment cycles (7+4+3 days), in addition to the elective antibacterial or antifungal pharmacological treatment for their diagnosis (BV or VVC).
干预措施: Class IIa vaginal medical device supplied as vaginal ovules, intended as an adjuvant in prevention of vaginal infections and symptoms. (Device)
PLACEBO
Participants receive placebo ovules (inert lipid base, free of active functional substances - no lactic acid, tyndallized probiotics, or sodium hyaluronate), identical in appearance and packaging to the active device, administered according to the same schedule, in addition to the elective antibacterial or antifungal pharmacological treatment.
干预措施: Placebo. (Other)
