Purpose
This is a phase I pharmacokinetic study of HIV positive patients stable on antiretroviral therapy who will switch treatment when enrolled from nevirapine to rilpivirine. On day 60 of the study the participants will attend clinic where they will have blood collected followed by a lumbar puncture where cerebrospinal fluid will be collected to measure drug concentration. The participants will then restart their original regime with nevirapine.

Primary Outcome Measures:
- CSF:plasma ratio of rilpivirine levels [ Time Frame: Day 60 ] [ Designated as safety issue: No ]The levels of rilpivirine will be measured in the cerebral spinal fluid and plasma after 60 days of exposure
Secondary Outcome Measures:
- Number of subjects with HIV viral load above 50 copies per mL [ Time Frame: Day 3, 7, 14, 28, 42, 60, 80-100 ] [ Designated as safety issue: Yes ]Plasma viral load will be measured at all study visits to assess if viral load is above the lower limit of detection (50 copies mL)

Detailed Description:
To investigate the following parameters in HIV-infected patients switching antiretroviral therapy from TDF/FTC/nevirapine to TDF/FTC/rilpivirine for 60 days:
- CSF exposure and CSF : plasma ratio of rilpivirine
- Safety and tolerability of switching antiretroviral therapy from TDF/FTC/nevirapine to TDF/FTC/rilpivirine
- Changes in cerebral metabolites measured via 1-H MRS after switching antiretroviral therapy to TDF/FTC/rilpivirine
- Seminal fluid exposure of rilpivirine
Eligibility| Ages Eligible for Study: | 18 Years and older |
| Genders Eligible for Study: | Male |
| Accepts Healthy Volunteers: | No |
Criteria
Inclusion Criteria:
- HIV-1 infected males subjects
