About
This is a randomised, parallel group, partly blinded investigation to evaluate the clinical performance and safety of pHyph in adult women with bacterial vaginosis. Patients will be randomised to active treatment or no treatment (untreated controls) in a 1:1 ratio. The Investigators carrying out the gynaecological assessments will be blinded. Patients will not be blinded.
The population of this investigation will consist of post-menarchal, pre-menopausal females 18 years or older seeking treatment for BV symptoms ("fishy smell", irritation and burning).
Approximately 82-92 patients will be recruited and randomised. BV will be diagnosed according to Amsel's criteria, defined as having at least 3 of the 4 criteria.
Active treatment (from the start of the investigation) will be compared to no treatment at day 7 after screening (primary endpoint). Clinical cure rate on Day 7 is defined as the absence of all of the following 3 Amsel criteria:
Patients receiving rescue treatment before Day 7 will be considered as treatment failures.
Patients in the "no treatment group" will receive pHyph as rescue treatment if they are not cured day 7. They will thereafter follow the same scheme as the patients starting with pHyph treatment.
After the initial pHyph treatment, daily during 6 days, patients will continue with pHyph twice weekly until day 25 when an additional assessment will be performed. If the patients are cured, they will continue to receive pHyph as preventive treatment during 6 weeks and possible BV recurrences will be assessed.

Inclusion criteria
Willing and able to give written informed consent for participation in the clinical investigation, and to comply with all clinical investigation requirements.
Adult, post-menarchal, pre-menopausal women aged 18 years or older.
Diagnosis of BV according to Amsel's criteria, defined as having at least 3 of the 4 following criteria:
Negative urine pregnancy test at screening.
Willing to refrain from using any intravaginal products (e.g., contraceptive creams, gels, foams, sponges, lubricants or tampons, etc.) until Day 7 and the following 24 hours after each pHyph administration during weekly treatment.
Willing to use condoms during any sexual intercourse with a male sexual partner until the initial pHyph treatment is completes. For patients starting with pHyph on Day 0, this means from Visit 1 (Day 0) until Visit 2 (Day 7). For patients that do not receive any treatment between Day 0 and Day 7, this means from Visit 1 (Day 0), and if they receive pHyph from Day 7, until their Visit 2 (Day 14).
Willing to use a method of contraception, e.g., condoms, hormonal contraception (oral, injectable, implantable, intravaginal, or transdermal), intrauterine device (IUD) or intrauterine hormone-releasing system (IUS), during any sexual intercourse that might result in pregnancy from Visit 2 (Day 7 or 14) until Visit 4 (70-77 days) to prevent pregnancy.
