Phase 4
Completed
Conditions
HIV Infections
Registration Number
NCT00106379
Lead Sponsor
Gilead Sciences
Brief Summary

The purpose of this study is to provide long-term clinical safety and efficacy data for tenofovir disoproxil fumarate and emtricitabine in HIV-infected patients experiencing various degrees of renal impairment.

Detailed Description

The primary objective of this study is as follows:

* To evaluate the safety and tolerability of tenofovir following administration of tenofovir disoproxil fumarate 300 mg for 48 weeks in HIV-infected patients experiencing various degrees of renal impairment.

The secondary objectives of this study are as follows:

* To evaluate the safety and tolerability of emtricitabine following administration of emtricitabine 200 mg for 48 weeks in HIV-infected patients experiencing various degrees of renal impairment.

* To evaluate the efficacy of tenofovir disoproxil fumarate in combination with emtricitabine in renally-impaired HIV-infected patients.

* To evaluate the pharmacokinetics of tenofovir and emtricitabine in renally-impaired HIV-infected patients.
