Clinical Performance and Safety of the Gedea Pessary in Adult Women With Bacterial Vaginosis (Nefertiti)
A Randomised, Double-blind, Placebo-controlled Study to Evaluate Clinical Performance and Safety of the Gedea Pessary in Adult Women With Bacterial Vaginosis
This is a randomised, double-blind placebo-controlled multi-centre study to evaluate clinical performance, safety and local tolerability of initial and preventive treatment with Gedea Pessary in adult women with confirmed BV.
The study population will consist of post-menarchal, pre-menopausal females 18 years or older seeking for BV symptoms (fishy smell, irritation and burning).
Patients will be recruited at study sites' gynaecological and sexual health clinics and a total of 150 patients are planned to be randomised in the study.
On Day 0, patients will have gynaecological examination, vaginal samples taken, and will be randomised in a 4:1 relation to receive treatment with 6 doses of the Gedea Pessary or a vehicle control (placebo) to be self-administered daily (Days 0 to 5). Patients will be re examined at Day 7 (+2 days) for clinical cure rate.
Patients that are clinically cured at Day 7 will continue to the second part of the study and will be randomised in a 1:1 relation to either Gedea Pessary or placebo treatment, to be self administered once a week for a duration of 126 days.
Patients not clinically cured at Day 7 will be offered rescue treatment (metronidazole) for 7 days. They will return at Day 14 for clinical assessment and sampling for microbiome and mycobiome analysis, and if cured they will be assessed for recurrence up to Day 128. Patients that are not cured at Day 14 will be discontinued from the study.
Patients that are clinically cured at Day 7 and continuing in Part 2 will be followed up until confirmed recurrence or Day 128 if no recurrence. Vaginal samples will be taken by self-swab on Days 35, 63 and 91, a visit to the clinic will be performed at Day 63 and telephone follow up will be done at Days 35 and 91. Vaginal samples will also be taken at the visit on the Day of potential recurrence and/or at Day 128 if no recurrence.
Vaginal samples will be used for confirming the diagnosis (Nugent score on Day 0 and Day 7) and sequencing analysis of the vaginal microbiome and mycobiome (Days 0, 7, 35, 63, 91 and Day of confirmed recurrence or Day 128 if no recurrence).
Patient follow-up as regards to patient questionnaire/usability, AEs and BV recurrence notification will be handled with a mobile phone application. In case of a suspected BV recurrence, the patient should return to the clinic for confirmation of BV diagnosis.
