Clinical Trial Summary

Prospective, Therapeutic Drug Monitoring Study of Reduced-Dose Efavirenz (400 mg) Plus Tenofovir Disoproxil Fumarate (TDF) and Lamivudine in a Fixed-Dose Combination Tablet (Combo) for Patients Receiving Co-Formulated TDF, Emtricitabine and Efavirenz (Atripla) with Viral Suppression in Taiwan


Clinical Trial Description

Efavirenz (EFV) is the most widely used non-nucleoside reverse transcriptase inhibitor (NNRTI). The recommended dose of EFV is 600 mg daily; however, a phase II study showed no significant difference in viral suppression rates across the different EFV groups (200 mg, 400 mg, and 600 mg) at 24 weeks. The week 96 analysis of ENCORE 1 study confirmed the durable virological non-inferiority of EFV 400 mg to the standard 600 mg dose when given as initial therapy with tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC). Fewer EFV-related adverse events (AEs) and fewer treatment discontinuations were also observed in the reduced dose group. The efficacy and safety findings provide robust evidence to redefine the EFV dose for HIV treatment. ;
