About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients who are postmenarcheal, nonpregnant biological females, 12 years of age and older, at Screening;

A potassium hydroxide (KOH) wet mount or saline wet mount preparation performed from the inflamed vaginal mucosa or secretions demonstrating yeast forms (hyphae or pseudohyphae) of or budding yeast;

Vaginal pH ≤4.5; and

Total Vulvar Signs and Symptoms (VSS) Scale score of ≥4: vulvovaginal signs (edema, erythema, and excoriation/fissures) and symptoms (vulvovaginal burning, itching, and irritation) as rated using the VSS Scale.

Disqualifiers

Patients with known or suspected other active infectious causes of cervicitis, vaginitis, or vulvitis (eg, BV, Chlamydia trachomatis, Neisseria gonorrhoeae, T. vaginalis, or genital lesions consistent with HPV, herpes simplex, syphilis, chancroid, etc) based on the results of clinical assessments, in-clinic microscopic assessments (eg, clue cells or trichomonads detected on saline wet mount), and/or rapid diagnostic tests (RDTs) performed prior to enrollment (eg, OSOM® test, etc);

Patients who have undergone any vaginal rejuvenation procedure (ie, laser) within 4 weeks prior to Screening or plan to undergo a vaginal rejuvenation procedure prior to completion of the last planned assessment;

Patients who will undergo evaluation or treatment during the clinical study for abnormal cytology or findings from high-risk HPV testing or Pap test finding;

A fishy odor of the vaginal discharge before or after the addition of a drop of 10% KOH (ie, a positive whiff test);

Trial design

Design model

Parallel

Treatments tested in this trial

  • Boric acid

    Drug

    Boric acid vaginal inserts consisting of 600 mg boric acid drug substance filled into white, opaque hypromellose capsules with no additional excipients included in the formulation. Each vaginal insert is sealed into a clear blister cavity.

  • Placebo

    Other intervention

    Placebo vaginal inserts containing anhydrous lactose and 1% magnesium stearate are also manufactured and filled into white, opaque hypromellose capsules. Packaged in clear blisters.

Trial outcomes

Primary outcomes

1

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; * Mild = 1; * Moderate = 2; or * Severe = 3.

Time frame
28 days (+ 2 days)

Secondary outcomes

1

Proportion of patients with clinical cure at the end-of-treatment visit

Proportion of patients with clinical cure at the end-of-treatment visit in the modified intent to treat (mITT) and clinically evaluable (CE) populations.

Time frame
15 days (+ 2 days)
2

Proportion of patients with clinical cure at the test-of-cure visit

Proportion of patients with clinical cure at the test-of-cure (TOC) visit in the per protocol and clinically evaluable (CE) populations.

Time frame
28 days (+ 2 days)
3

Proportion of patients with mycological eradication at the end-of-treatment visit

Proportion of patients with mycological eradication at the end-of-treatment (EOT) visit in the modified intent to treat (mITT) population.

Time frame
14 days (+ 2 days)
4

Proportion of patients with mycological eradication at the test-of-cure visit

Proportion of patients with mycological eradication at the test-of-cure (TOC) visit in the modified intent to treat (mITT) and clinically evaluable (CE) populations.

Time frame
28 days (+ 2 days)
