Study Description

Brief 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.

Condition or disease Intervention/treatment Phase
Hepatitis Delta Virus Drug: Lonafarnib Drug: Ritonavir Drug: PEG IFN-alfa-2a Drug: Placebo Lonafarnib Drug: Placebo Ritonavir Phase 3

Detailed Description:

This partially double-blind, randomized study will employ a matrix (factorial) design to evaluate the efficacy and safety of LNF 50 mg/RTV 100 mg twice per day (BID) with and without PEG IFN-alfa-2a 180 mcg once-weekly (QW) for 48 weeks compared to no treatment (placebo LNF and placebo RTV) in patients chronically infected with hepatitis delta virus (HDV) and receiving anti-HBV (hepatitis B virus) nucleos(t)ide maintenance therapy.

Approximately 400 patients will be randomized with an allocation ratio of 7:5:2:2 All patients will receive/maintain background anti-HBV nucleos(t)ide therapy with entecavir or tenofovir for at least 12 weeks prior to initiating study therapy.

All patients who complete 48 weeks of treatment will have a liver biopsy for histology assessment at EOT and will be followed for an additional 24 weeks off study treatment.

  2. To compare the composite virologic and biochemical response rate at EOT in patients who receive LNF 50 mg/RTV 100 mg BID with PEG IFN-alfa-2a 180 mcg QW vs patients who receive placebo. [ Time Frame: 48 weeks ]

Secondary Outcome Measures :
  1. To compare the histologic response rate at EOT in patients who receive LNF 50 mg/RTV 100 mg BID vs patients who receive placebo. [ Time Frame: 48 weeks ]
  2. To compare the histologic response rate at EOT in patients who receive LNF 50 mg/RTV 100 mg BID with PEG IFN-alfa-2a 180 mcg QW vs patients who receive placebo. [ Time Frame: 48 weeks ]
