Efficacy as determined by HIV-1 seroconversion rate per person-years of product use, measured at the end of the investigational product use period.
The primary endpoint is HIV-1 seroconversion measured by rapid and specialized laboratory tests according to a comprehensive HIV testing algorithm. This algorithm employs a series of high specificity and high sensitivity immunoassay-based HIV blood tests that minimize the chance of false positive results to determine if a subject is positive for HIV. Endpoint confirmation of HIV infection is by Western blot.
Time frame: 15 months
Safety as determined by grade 3 and 4 AE's, clinically significant grade 2 laboratory findings (based on DAIDS grading) and all serious AE's.
This will be measured by self-reports, physical examination, safety laboratory tests and other specialised investigations.

Adherence to the protocol-specific product regimen as determined by self-reported diary cards and questionnaires.
Time frame: 15 months
