Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Clinical Cure as Assessed by the Investigator at the Test-of-cure Visit | 7-14 days after beginning treatment | The percentage of participants with clinical cure in each arm was compared. Clinical cure of bacterial vaginosis is defined as 1. discharge has returned to normal/physiologic, 2. the whiff test is negative for any amine fishy odor, 3. the saline wet mount is \<20% clue cells |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Improvement of BV Clue Cells | 7-14 days after beginning treatment | Clue cells on wet mount were assessed and categorized as absent (\<20%) or present (\>=20%). Absence of clue cells is associated with improvement. The comparison was for percentage between arms for clue cells absent (\<20%). |
| Microbiologic Improvement/Cure | 7-14 days after beginning treatment | For bacterial vaginosis (BV), Gram stain Nugent scores are catergized as normal (0 to 3), intermediate (4 to 6) or BV (7 to 10). Normal scores are associated with BV microbiologic cure. The percentage of participants with normal scores were compared between treatments. |
| Number of Participants Reporting Complete Resolution of Symptoms by Test of Cure Visit | 7-14 days after beginning treatment | Subjects reported if symptoms completely resolved and the date of resolution. The percentage of participants reporting complete resolution of symptoms was compared between arms. |
| Number of Participants With Treatment Emergent Adverse Events | Any time during study participation (up to 30 days) | Adverse events were collected at study visits, from subject diaries and from spontaneous reports |

Outcome results
Clinical Cure as Assessed by the Investigator at the Test-of-cure Visit
The percentage of participants with clinical cure in each arm was compared. Clinical cure of bacterial vaginosis is defined as 1. discharge has returned to normal/physiologic, 2. the whiff test is negative for any amine fishy odor, 3. the saline wet mount is \<20% clue cells
Time frame: 7-14 days after beginning treatment
Population: mITT population (Baseline Gram stain Nugent score of 4 or more and used at least one dose of study medication)
| Arm | Measure | Value (COUNT_OF_PARTICIPANTS) |
|---|---|---|
| Metronidazole Vaginal Gel | Clinical Cure as Assessed by the Investigator at the Test-of-cure Visit | 47 Participants |
| Gel Vehicle | Clinical Cure as Assessed by the Investigator at the Test-of-cure Visit | 18 Participants |
Improvement of BV Clue Cells
Clue cells on wet mount were assessed and categorized as absent (\<20%) or present (\>=20%). Absence of clue cells is associated with improvement. The comparison was for percentage between arms for clue cells absent (\<20%).
Time frame: 7-14 days after beginning treatment
Population: mITT population (Baseline Gram stain Nugent score of 4 or more and used at least one dose of study medication)
