About this study
Official title: Safety and Efficacy Study to Assess 600 mg Boric Acid Vaginal Inserts With 7- or 14-Days Treatment of Vulvovaginal Candidiasis (VVC)
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.
Read the 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 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 KOH wet mount, saline wet mount, and vaginal fungal culture) will be performed. Additionally, screening tests required to rule out other potential causes of symptoms may be performed or repeated at PI or qualified designee discretion. Patients may also be provided with a rescue treatment at PI or qualified designee discretion.
Individual patient participation is expected to be 28 days.

What is being measured
The primary outcome is the main question the study is designed to answer.
Proportion of patients with the absence of all signs and symptoms of vulvovaginal candidiasis
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;

- Moderate = 2; or
- Severe = 3.
Measured: 28 days (+ 2 days)

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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 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 KOH wet mount, saline wet mount, and vaginal fungal culture) will be performed. Additionally, screening tests required to rule out other potential causes of symptoms may be performed or repeated at PI or qualified designee discretion. Patients may also be provided with a rescue treatment at PI or qualified designee discretion.
Individual patient participation is expected to be 28 days.

A Phase 3 study testing Boric acid in people with Vulvovaginal Candidiases and Vulvovaginal Candidiasis, Genital, run by pH-D Feminine Health LLC at 26 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 23 inclusion and 31 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 23 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 26 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Proportion of patients with the absence of all signs and symptoms of vulvovaginal candidiasis (time frame: 28 days (+ 2 days)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Oct 2026.
