A New Tablet Containing Two FDA-Approved Drugs In HIV-Infected Patients Who Have Not Received Prior Therapy
A Phase III, Randomized, Open-label, Multicenter Study of the Safety and Efficacy of Efavirenz Versus Tenofovir When Administered in Combination With the Abacavir/Lamivudine Fixed-dose Combination Tablet as a Once-daily Regimen in Antiretroviral-naive HIV-1 Infected Subjects.
This is a 48-week study to evaluate the safety and efficacy of a new tablet formulation containing two FDA-approved drugs in HIV-infected patients who have not received prior therapy. This tablet will be taken with one of two FDA-approved drugs as a once-daily regimen. Study physicians will evaluate subjects to determine if they have certain medical conditions, laboratory test values, medication use, or drug allergies that would exclude them from the study.
