Study Stopped
This study was initially planned to enroll patients in Mongolia. However, due to challenges in setting it up in Mongolia, this study was later determined not to be initiated.

Conditions
Outcome Measures
Primary Outcomes (1)
Change from baseline in HDV viral load at Week 72 visit (end of follow-up)
HDV RNA viral load will be quantified with a real-time qPCR assay with a lower limit of quantification (LLOQ) of 14 IU/mL
72 weeks
Secondary Outcomes (7)
Change from baseline in HDV viral load at Week 48 visit (end of treatment, EOT)
48 weeks
Proportion of patients with histological response
72 weeks
Proportion of patients with sustained virologic response: HDV RNA below the LLOQ 12 weeks after EOT (48 weeks)
60 weeks
Proportion of patients with sustained virologic response: HDV RNA below the LLOQ 24 weeks after EOT (48 weeks)
72 weeks
Number of participants with treatment-emergent changes in clinical laboratory findings
48 weeks
- +2 more secondary outcomes
Study Arms (3)
LNF 25 mg bid and RTV 100 mg bid
ACTIVE COMPARATORPatients will take lonafarnib 25 mg BID and ritonavir 100 mg BID. Patients will also take an anti-hepatitis B virus (HBV) nucleos(t)ide analog (NUC) from the first dose of LNF through the end of the study.
LNF 50 mg bid and RTV 100 mg bid
ACTIVE COMPARATORPatients will take lonafarnib 50 mg BID and ritonavir 100 mg BID. Patients will also take an anti-hepatitis B virus (HBV) nucleos(t)ide analog (NUC) from the first dose of LNF through the end of the study.
LNF 100 mg bid
ACTIVE COMPARATORPatients will take lonafarnib 100 mg BID. Patients will also take an anti-hepatitis B virus (HBV) nucleos(t)ide analog (NUC) from the first dose of LNF through the end of the study.
Interventions
antiviral farnesyltransferase inhibitor
CYP 3A4 inhibitor, lonafarnib booster
Eligibility Criteria
You may qualify if:
- Willing and able to comply with study procedures and provide written consent
- years old
- Body mass index (BMI) of ≥ 18 kg/m2 and weighs ≥ 45 kg
- CHD infection of at least 6 months' duration documented by a positive HDV antibody (Ab) test and HDV RNA ≥ 3 log10/mL by qPCR at study entry
- Serum ALT \> upper limit of the normal range (ULN) and \< 10 × ULN
- Liver biopsy within 12 months of Day 1 demonstrating evidence of chronic hepatitis. If no liver biopsy is available, the patient must be willing to consent to and have no contraindication to liver biopsy
- ECGs demonstrating no acute ischemia or clinically significant abnormality and a QT interval corrected for heart rate (QTcF) \< 450 ms for male patients and \< 460 ms for female patients
- Dilated retinal examination ≤ 1 year before screening: For patients with diabetes, hypertension, or other risk factors for retinal disease, performed by a licensed ocular specialist; for all other patients, a normal retinal examination as assessed by the investigator or a licensed ocular specialist
- Female patients of childbearing potential and male patients with partners of childbearing potential must agree to use adequate methods of contraception during the study and for 90 days after the last dose of study drug. Female patients of childbearing potential are all those except patients who are surgically sterile, who have medically documented ovarian failure, or who are at least 1 year postmenopausal.
- For females: 2 of the following contraceptive methods, with at least 1 being a barrier method:
- Hormonal contraceptives for ≥ 3 months before screening
- Intrauterine device (IUD) in place ≥ 3 months before screening
- Double-barrier methods (use of condom \[male partner\] with either diaphragm with spermicide or cervical cap with spermicide) from screening
- Surgical sterilization of the partner (vasectomy ≥ 1 month before screening)
- For males:
- +4 more criteria
You may not qualify if:
- Participation in a clinical trial with, or use of, any investigational agent within 30 days before screening
- Previous use of LNF.
- Female patients who are pregnant or breastfeeding. Male patients must confirm that their female sexual partners are not pregnant. Female patients must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin \[hCG\]) within 24 hours prior to the start of any investigational agent).
- Current or previous history of decompensated liver disease (Child-Pugh Class B or C)
- Co-infected with human immunodeficiency virus (HIV) or hepatitis C virus (HCV).
- Positive results for HIV or HCV Ab at screening. Patients with a positive HCV Ab at screening are allowed if they have completed a curative antiviral regimen and have documented undetectable HCV RNA for at least 3 months before screening and at screening.
- Past history or current evidence of decompensated liver disease, defined as any of the following at screening:
- Bilirubin level ≥ 2.5 mg/dL unless due to Gilbert's disease
- Serum albumin level \< 3.0 g/dL
- International normalized ratio (INR) ≥ 1.5
- Evidence of significant portal hypertension such as hepatic venous pressure gradient (HVPG) ≥ 10 mmHg; current presence or history of esophageal or abdominal varices, variceal bleeding, or splenomegaly \> 12 cm length on imaging
- Current evidence or history of ascites requiring diuretics or paracentesis, or hepatic encephalopathy
- Current evidence or history of hepatic encephalopathy
- Any of the following abnormal laboratory test results at screening:
- Platelet count \< 90,000 cells/mm3
- +40 more criteria
