- Brief Summary
This is a Phase 3 clinical study to evaluate the efficacy, safety, and tolerability of boric acid 600 mg vaginal inserts in patients with VVC.
- Detailed Description
This clinical study will be a multi-center, randomized, placebo-controlled, double-blinded study with a 3-arm design comparing 600 mg boric acid vaginal inserts dosed for 7 or 14 days to placebo. All patients will self-administer vaginal inserts once daily for 14 days.
During self-administration of the study drug, patients will be instructed to utilize an electronic diary (eDiary) to record their daily symptoms from Screening through Day 28 (Visit 5). The following information will be recorded in the eDiary:
* Study drug administration (including time at which study drug was administered, activity following study drug administration, and whether the bladder was emptied prior to administration);
* Vulvovaginal symptoms;
* Any adverse symptoms or symptoms of concern, illnesses, or physical injuries that occur while participating in the clinical study;
* Contraceptive methods utilized;
* Days of menstrual bleeding, including days of heavy menstrual bleeding (defined as "flooding" or bleeding through ≥1 tampon or sanitary pad in 2 hours or less), start date of menstrual cycle, end date of menstrual cycle, and daily quantity of menstrual hygiene product(s) utilized for each day of menses;
* Position (eg, laying down supine, prone, on side) following study drug administration;
* Vulvovaginal sexual activity, including if the sexual activity occurred before or after study drug administration; and
* The presence of any non-exclusionary intravaginal foreign objects (ie, contraceptive vaginal ring, diaphragm, cervical cap, condom, sex toys).
Patients will complete a total of 4 in-person visits at Screening, on Day 7 (Visit 2) (±2 days), Day 15 (Visit 3) (+2 days), and Day 28 (Visit 5) (±2 days), as well as a telephone Follow-Up Visit on Day 21 (Visit 4) (±2 days) (if clinically indicated, the Follow-Up Visit may be performed in-person).
Clinical, mycological, and overall outcomes (as defined in Sections 7.3, 7.4, and 7.5, respectively) will be assessed at Day 15 (Visit 3) and Day 28 (Visit 5) for all study arms. If persistent symptoms are present at any visit, a full microbiologic evaluation to assess for persistence of VVC (including both wet mount and fungal culture) will be performed. Additionally, screening tests required to rule out potential other causes of symptoms may be repeated at PI discretion. Patients may also be provided with a rescue treatment at PI discretion.
Individual patient participation is expected to be 28 days.

- Primary Outcome Measures
Name Time Method Proportion of patients with the absence of all signs and symptoms of vulvovaginal candidiasis 28 days (+ 2 days) The proportion of patients who achieve clinical cure (defined as the absence of all signs and symptoms of vulvovaginal candidiasis (VVC) \[ie, composite VSS score = 0\] in the absence of additional antifungal treatment), at the test-of-cure (TOC) visit. This is the proportion of patients in the modified ITT (mITT) Population with clinical cure.
* Signs: vulvovaginal edema, erythema, excoriation/fissures;
* Symptoms: vulvovaginal itching, burning, irritation; and
* Severity of each sign and symptom graded on a 0 to 3 rating scale:
* Absent = 0;
* Mild = 1;
