Efficacy and Safety of Vaginal Lactobacillus Dual Probiotic Capsules in Bacterial Vaginosis

China402 participantsStarted 2024-06-12

Plain-language summary

Primary Objective: To confirm that the clinical cure rate of Vaginal Lactobacillus Dual Probiotic Capsules for bacterial vaginosis (BV) is superior to placebo at the 21-30 day post-treatment visit (Day 21 to Day 30). Key Secondary Objective: To compare the clinical cure rate of Vaginal Lactobacillus Dual Probiotic Capsules versus placebo for BV at the 15-18 day post-treatment visit (Day 15 to Day 18). Other Secondary Objectives: 1) To comprehensively assess the therapeutic efficacy of the study drug versus placebo for BV at Day 15 to 18 and Day 21 to 30; 2) To evaluate the safety profile of the study drug for BV treatment compared with placebo, including adverse events and clinical laboratory findings. Study Design \& Randomization: This is a multicenter, randomized, double-blind, placebo-controlled Phase III clinical trial. An independent biostatistician generated the subject and drug randomization lists via SAS software, which were imported into an Interactive Web Response System (IWRS). Investigators at each site obtain randomization and drug numbers through the IWRS for subject allocation. Blinding \& Allocation Concealment: Double-blinding is implemented for both investigators and subjects. The study drug and placebo are identical in appearance, shape, specification, and dosage form. Blinding procedures are performed by personnel unrelated to the trial, with a complete and detailed record of the entire blinding process maintained throughout the study.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
