Study hypothesis
This study is to confirm the safety, tolerability and the pharmacokinetic profile of the hydrochloride forumation in healthy female volunteers. This treatment is expected to be effective in the treatment of patients diagnosed with bacterial vaginosis.
Hypothesis:
The concentrations of clindamycin (fee base) in plasma at pre-determined time-points.
Please note that as of 18/10/2007 the anticipated end date of this trial was extended from 09/10/2007.

Intervention
Pre-trial visit:
Prior to interventions, written informed consent will be gained. A screening assessment and a compliance check will be performed the day before dosing.
Day one:
Pre-dose checks, vitals, menstrual history check, a pre-dose pharmacokinetic (PK) sample and vaginal pH testing will be performed, and a check to see if the volunteer has any signs or symptoms of infection will also be performed.
After this, the study drug (100 mg Clindamycin Hydrochloride Vaginal Insert) will be administered (dosing period = 24 hours). Post insertion checks will include comfort questionnaires, PK blood samples, vitals and vaginal pH. The study drug will be removed at 24 hours and a urine sample for urinalysis will be taken.
Day two:
PK blood samples will be taken.
Days 3, 4, 5 and 6:
PK blood sample, vitals and urine sample for urinalysis information will be taken.
Adverse Events (AEs) and concomitant medication checks will be performed throughout the trial.
Post-trial visit:
Vitals, Electrocardiogram (ECG), safety bloods and urine samples, urine for pregnancy testing and a physical examination will be performed.

Clindamycin
Primary outcome measure
The concentrations of clindamycin (free base) in plasma at pre-determined time-points.
Secondary outcome measures
1. Assessments of all adverse events reported
2. Assessment of tolerability by review of completed comfort questionnaires
3. Assessment of vaginal pH at specified time-points
4. Measurements of residual amounts of clindamycin in used CHVI to calculate the remaining dose of clindamycin in order to determine the amount of drug released from the insert
