Study Summary

Two LNF-containing regimens will be evaluated in the D-LIVR Phase 3 study: (1) LNF/RTV/PEG IFN-alfa-2a and (2) LNF/RTV. Each of these arms will have efficacy endpoints that measure clinical benefit with regard to viral suppression and alanine aminotransferase (ALT) normalization. For each LNF-containing regimen, a composite endpoint of EOT (48 weeks) virologic response and ALT normalization will be used. Virologic response will be defined as a 2 log10 IU/mL reduction from baseline.
