  Purpose
The purpose of this clinical research study is to assess the pharmacokinetics of atazanavir, identifying one or more dosing regimens of atazanavir/ritonavir/tenofovir when dosed with famotidine results in atazanavir exposures similar to those when atazanavir/ritonavir/tenofovir 300/100/300 mg is dosed without famotidine in healthy subjects.

HIV Infections Drug: Atazanavir+Ritonavir+Tenofovir Drug: Atazanavir+Ritonavir+Tenofovir+Famotidine Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Official Title: Randomized, Open-Label, Multiple-Dose Study to Evaluate the Effect of Famotidine on the Pharmacokinetics of Atazanavir/Ritonavir/Tenofovir in Healthy Subjects

Primary Outcome Measures:
  • Assess PK of ATV, identifying dosing regimens of ATV/RTV/TDF when dosed with FAM that result in ATV exposures similar to ATV/RTV/TDF 300/100/300 mg with and without FAM.

Secondary Outcome Measures:
  • Assess PK , safety, and tolerability of ATV/RTV/TDF with and without FAM.

Estimated Enrollment: 40
