Efficacy and Safety Study of SPL7013 Gel to Prevent the Recurrence of Bacterial Vaginosis (BV)

Phase 3
Completed
Conditions
Bacterial Vaginosis
Interventions
Drug: 1% SPL7013 Gel
Drug: Placebo gel
Registration Number
NCT02237950
Lead Sponsor
Starpharma Pty Ltd
Brief Summary

A double-blind, phase 3 study to determine the efficacy of SPL7013 Gel when administered on alternate days for 16 weeks, compared to placebo gel in preventing the recurrence of BV in women with a history of recurrent BV.

Detailed Description

Eligible participants, with both a history of recurrent BV and a current episode of BV, will receive a seven-day course of oral metronidazole. Participants who are successfully treated for their BV, and continue to be eligible, will be randomly assigned to receive either 1% SPL7013 Gel or placebo gel on alternate days at bed-time for 16 consecutive weeks.

The primary endpoint will be determined at the conclusion of this 16 week treatment phase.

Participants who experience a BV recurrence will be considered to have completed the study. Such participants will receive BV treatment in line with local practice and will not attend any further study visits.

Participants who successfully reach Week 16 without a BV recurrence will enter a 12-week follow-up phase to Week 28.

Participants will attend a study visit at 4-weekly intervals throughout the duration of the study to Week 28 (or up to the point of BV recurrence) to assess recurrence of BV and adverse events.

Secondary Outcome Measures
NameTimeMethod
Recurrence of Individual Amsel CriteriaAt or by the Week 16 visit

Number of participants with positive individual Amsel criterion

- Clue cells representing at least 20% of total epithelial cells

Time to Recurrence of BV Where a Diagnosis of BV is Defined as the Presence of at Least 3 Clinical FindingsAt or by the Week 16 visit

Time to recurrence of BV (days), where a diagnosis of BV is defined as the presence of at least 3 clinical findings (Amsel criteria)

Recurrence of Patient-reported BV SymptomsAt or by the Week 16 visit

Number of participants with self-reported BV symptoms (vaginal discharge and/or odor)

Recurrence of BV as Determined by Presence of a Nugent Score of 7-10At or by the Week 16 visit

Number of participants with a recurrence of BV as determined by presence of a Nugent score of 7-10 (BV), where 0-3 is normal, and 4-6 is intermediate.

Recurrence of BV Where a Diagnosis of BV is Defined as the Presence of at Least 3 Clinical FindingsAt or by the Week 24 visit

Number of participants with a recurrence of BV, where a diagnosis of BV is defined as the presence of at least 3 clinical findings (Amsel criteria)

Recurrence of BV According to the Composite Definition of at Least 3 Clinical Findings (Amsel Criteria) and a Nugent Score of 4-10.At or by the Week 16 visit

Number of participants with a recurrence of BV according to the composite definition of at least 3 clinical findings (Amsel criteria) and a Nugent score of 4-10 (intermediate to BV), where 0-3 is normal.

Change From Baseline in Brief Index of Sexual Functioning for Women Questionnaire Composite ScoreBaseline to Week 16

Change from baseline in brief index of sexual functioning for women (BISF-W) questionnaire composite score. The composite score includes scores from dimensions (D) of thoughts/desire (D1, 0-12), arousal (D2, 0-12), frequency of sexual activity (D3, 0-12), receptivity/initiation (D4, 0-12), pleasure (D5, 0-12), relationship satisfaction (D6, 0-12), and any problems affecting sexual functioning (D7, 0-16). The composite score is calculated as D1+D2+D3+D4+D5+D6-D7 with a range of -16 to +75. A positive change in composite score from baseline to Week 16 reflects an improvement in sexual functioning, with a greater change in score indicating a greater improvement in sexual functioning.

Adverse Events (AEs)From Baseline to end of Week 28
