Description of intervention(s) / exposure
A study to investigate the safety, tolerability, pharmacokinetic, pharmacodynamics of R131 vaginal ointment in healthy women volunteers after multiple doses of 150mg or 300mg.

The study will comprise of two cohorts. Cohort 1 will involve the first period comprising of a single 150mg dose of R131 or placebo vaginal ointment with PK blood sapmling during confinement and then the second period comprising of 21 daily doses of 150mg of R131 or placebo vaginal ointment followed by PK blood sampling. Cohort 2 will be administered a 300mg dose of R131 or placebo vaginal ointment in the same dose regimen as cohort 1.

Cohort 2 will commence following review and approval of DSMB.

The ointment will be self-administered into the vagina. Full instructions will be given as to its application. Participants will also be asked to provide a vaginal swabs at various intervals throughout the study. The ointment will be given to participants to take home along with the study questionnaires. A diary will also be completed by each participant.

To monitor adherence to the intervention product used ointment applicators will be returned and weighed, each participant will be given a diary to complete daily, vaginal swabs will be performed on Day 1, 8, 15 and 21.

Pre and post study laboratory tests will be completed to assess the health of participants. The intervention for this study is the ointment formulation of R131.

Outcomes
Primary outcome [1] 305944 0
To compare the bioavailability of Ritonavir (as summarised by Cmax and AUC) for the formulation. All plasma samples will be assayed for Ritonavir using one fully validated LC/MS/MS method. Validation will be conducted to comply with FDA guidelines.
Timepoint [1] 305944 0
Day 1-2: 0, 1, 2, 4, 8, 12, 24. Day 22-23: 0, 1, 2, 4, 8, 12 and 24 hours after dosing
Primary outcome [2] 305945 0
To evaluate the safety (as summarised by adverse events, vital signs and ECG).
Timepoint [2] 305945 0
Adverse events will be assessed continuously from dosing until release from confinement period in each cohort.

Vital signs will be:
Screening
Period 1 - Day 1 baseline and at 12 and 24 hours.
Period 2 - Day 8, Day 15, Day 22 at 12 and 24 hours and on study exit
Primary outcome [3] 305974 0
To compare the bioavailability of Lopinavir (as summarised by Cmax and AUC) for the formulation. All plasma samples will be assayed for Lopinavir using one fully validated LC/MS/MS method. Validation will be conducted to comply with FDA guidelines.
Timepoint [3] 305974 0
Day 1-2: 0, 1, 2, 4, 8, 12, 24. Day 22-23: 0, 1, 2, 4, 8, 12 and 24 hours after dosing
Secondary outcome [1] 347088 0
Time to maximum peak concentration (Tmax) of R131 will be determined by plasma sample analysis. Tmax will be the time where the maximum concentration occurred in the sample points.

For those participants receiving the placebo, only samples around the expected Tmax i.e. 2-3 hours will be assayed with the pre-dosing samples.
Timepoint [1] 347088 0
Day 1-2: 0, 1, 2, 4, 8, 12, 24. Day 22-23: 0, 1, 2, 4, 8, 12 and 24 hours after dosing
Secondary outcome [2] 347089 0
Additional Primary Outcome: To evaluate tolerability (as summarised by participant questionnaires (vaginal irritation questionnaire))
Timepoint [2] 347089 0
The Daily Diary and vaginal irritation questionnaire will be completed each morning following each previous evening dose. This will occur at each visit to the clinical site (Days 1-2 and 21-22), at each participants home and at each visit to Zenith Technology during the study (Days 8 and 15) for a total of 21 days. In addition to answering specific questions concerning irritation, participants will use a rating scale to evaluate discomfort and severity.
Secondary outcome [3] 347295 0
Additional Primary Outcome: To evaluate pharmacodynamics (as summarised by participant rating scores designed specifically for the study)
Timepoint [3] 347295 0
The Daily Diary and vaginal irritation rating scores will be completed each morning following each previous evening dose. This will occur at each visit to the clinical site (Days 1-2 and 21-22), at each participants home and at each visit to Zenith Technology during the study (Days 8 and 15) for a total of 21 days.
