Brief summary

This Phase 2b trial is designed to provide a screening evaluation for the hypothesis that, following a 5-day treatment with MetroGel® to treat BV, L. crispatus CTV-05 (LACTIN-V, Osel, Inc.) administered at 2 x 10\^9 cfu/dose using a vaginal applicator reduces the 12-week incidence of BV recurrence when compared to placebo. The primary objectives of this study are: 1) To estimate the efficacy of repeated doses of LACTIN-V (2 x 10\^9 cfu/dose) as compared to placebo in preventing BV recurrence by 12 weeks following treatment of BV with MetroGel vaginal gel (MetroGel). 2) To assess the safety of LACTIN-V over 24 weeks by comparing the incidence of AEs between individuals randomized to LACTIN-V or placebo.

Detailed description

This is a Phase II-b multicenter randomized double-blind placebo-controlled trial to assess the efficacy of repeated doses of LACTIN-V compared to placebo in preventing BV recurrence in women diagnosed with BV. The study will also assess the safety of LACTIN-V by comparing the incidence of AEs between women randomized to LACTIN-V or placebo. The study plans to enroll 228 non-pregnant, pre-menopausal women age 18 to 45 years. Women will be randomized 2:1 to receive LACTIN-V or placebo. Potentially eligible women will start a standard 5-day course of MetroGel. Women will return to the study clinic within 2 days after completing the 5-day course of MetroGel to re-evaluate eligibility criteria and review the BV test results from the screening visit. Women with Amsel criteria \> /=3 and Nugent score 4-10 will be instructed to administer the LACTIN-V or placebo at home for 5 consecutive days and then twice weekly for 10 weeks. The primary objectives of this study are: 1) To estimate the efficacy of repeated doses of LACTIN-V (2 x109 cfu/dose) as compared to placebo in preventing BV recurrence by 12 weeks following treatment of BV with MetroGel vaginal gel (MetroGel). 2) To assess the safety of LACTIN-V over 24 weeks by comparing the incidence of AEs between individuals randomized to LACTIN-V or placebo. Secondary objectives are: 1) To investigate the colonization of LACTIN-V (presence of L. crispatus CTV-05 in the vaginal specimen) and fluctuations over 12 weeks, in relation to menses and sexual intercourse 2) To evaluate user acceptability and tolerability of LACTIN-V over 12 weeks, including perceptions around method of delivery and dosing. 3) To measure long-term colonization of LACTIN-V at 24 weeks (12 weeks after last dosing) 4) To estimate the long-term efficacy of repeated doses of LACTIN-V (2 x 109 cfu/dose) as compared to placebo in preventing BV recurrence at 24 weeks (12 weeks after last dosing)

Design outcomes

Primary

MeasureTime frameDescription
The Proportion of Participants Reporting Product-related Adverse Events (AEs) and Serious Adverse Events (SAEs) in Each Study Arm.Day 1 to Day 168Adverse events and serious adverse events were collected during the entire study period. Relatedness to study product was assessed by the site investigator according to the protocol definition of related as There is a reasonable possibility that the study product caused the AE. Reasonable possibility means that there is evidence to suggest a causal relationship between the study product and the AE.
The Proportion of Participants With a Positive BV Diagnosis in Each Study Arm.Day 1 to Day 84A positive BV diagnosis was defined by meeting at least 3 of the 4 Amsel criteria and a Nugent score of 4-10. Amsel criteria are: homogeneous, thin, grayish-white discharge that smoothly coats the vaginal walls; vaginal pH \>4.5; positive whiff-amine test, defined as the presence of a fishy odor when a drop of 10% potassium hydroxide is added to a sample of vaginal discharge; and presence of clue cells (\>20%) on microscopy. The Amsel score ranges from 0-4, where higher scores mean a worse outcome. The Nugent score is calculated by assessing for the presence of large Gram-positive rods scored as 0 to 4, small Gram-variable rods scored as 0 to 4, and curved Gram-variable rods scored as 0 to 2, and adding all component scores. The Nugent score ranges from 0-10, where higher scores mean a worse outcome. All BV diagnoses following 15 days after enrollment (22 days after commencement of MetroGel treatment) were considered a recurrent episode.

Colonization of L. crispatus was determined from the concentrations of L. crispatus species and L. crispatus CTV-05 obtained from qPCR. Successful colonization was defined as: If CTV-05 concentration was above the lower limit of detection (LLOD) and the L. crispatus was above the LLOD, then successful colonization had occurred. If either CTV-05 or L. crispatus concentration was below LLOD or indeterminate, then successful colonization had not occurred.

The Proportion of Participants Experiencing Successful Colonization With L. Crispatus CTV-05 Following Dose of Study Product by Occurrence of Menses.

Colonization of L. crispatus was determined from the concentrations of L. crispatus species and L. crispatus CTV-05 obtained from qPCR. Successful colonization was defined as: If CTV-05 concentration was above the lower limit of detection (LLOD) and the L. crispatus was above the LLOD, then successful colonization had occurred. If either CTV-05 or L. crispatus concentration was below LLOD or indeterminate, then successful colonization had not occurred. The LLOD for CTV-05 was 660 copies/mL and the LLOD for L. crispatus was 953 copies/mL

Time frame: Day 84

Population: The analysis population includes participants with results at the visit.

The Proportion of Participants Who Are Compliant With the Complete Dose Regimen as Assessed by Participant Reporting and Applicator Staining.

A subject was considered compliant with the assigned study product if she took 4 of the first 5 daily doses and at least 75% of the scheduled doses overall prior to the first diagnosis of BV or through Week 12, whichever occurred first. Compliance was assessed by subject report via the memory aid and, separately, applicator staining of the returned kit. Compliance was assessed on a weekly basis and the time (week) at which the subject became non-compliant was determined by blinded PI review.

Time frame: Day 1 to Day 84

Population: The analysis population was the intent-to-treat population (all randomized participants).

The Proportion of Participants With a Positive BV Diagnosis in Each Study Arm.

A positive BV diagnosis was defined by at least 3 of the 4 Amsel criteria and a Nugent score of 4-10. Amsel criteria are: homogeneous, thin, grayish-white discharge that smoothly coats the vaginal walls; vaginal pH \>4.5; positive whiff-amine test, defined as the presence of a fishy odor when a drop of 10% potassium hydroxide is added to a sample of vaginal discharge; and presence of clue cells (\>20%) on microscopy. The Nugent score is calculated by assessing for the presence of large Gram-positive rods scored as 0 to 4, small Gram-variable rods scored as 0 to 4, and curved Gram-variable rods scored as 0 to 2. All BV diagnoses following 15 days after enrollment (22 days after commencement of MetroGel treatment) were considered a recurrent episode.

Time frame: Day 1 to Day 168

Population: The analysis population was the intent-to-treat population (all randomized participants).
