raltegravir versus efavirenz in naive hiv-1-infected patients receiving rifampin for active tuberculosis

Conditions: HIV-1 Infection; Tuberculosis

Summary: phase iii trial evaluating raltegravir as an alternative to efavirenz for antiretroviral treatment of hiv-infected patients with tuberculosis.

phase iii multicenter, international, open-label, randomized trial evaluating non-inferiority of raltegravir at dose of 400mg bid compared to efavirenz 600mg qd, both in association with tenofovir disoproxil fumarate and lamivudine in art-naïve hiv-1 infected patients with active tb disease receiving a rifampin-based tb treatment initiated \<8 weeks before inclusion. patients will be randomized between 2 arms: the raltegravir (ral) 400 mg bid arm or the efavirenz (efv) 600 mg qd arm, each in combination with tenofovir disoproxil fumarate (tdf) and lamivudine (3tc) and will be followed for 48 weeks after entry in the trial (art initiation).
