Piranga Trial Summary

This trial will test the safety and effectiveness of new hepatitis B treatments in people with mild liver damage. It will compare different combinations of drugs against each other and a control group.

Who is the study for?
This trial is for adults with Chronic Hepatitis B who've been on NUC therapy for at least a year, have low HBV DNA levels, and normal liver enzyme ALT levels. They must not be pregnant or breastfeeding and agree to use contraception. Excluded are those with heart disease, drug abuse history, significant liver fibrosis/cirrhosis, recent cancer treatments or immunosuppressants.Check my eligibility
What is being tested?
The study tests the safety and effectiveness of new combination therapies (including PD-L1 LNA, PEG-IFN, TLR7 agents) in treating Chronic Hepatitis B compared to a control group. It includes screening up to 8 weeks, treatment up to 48 weeks and follow-up for another 48 weeks.See study design
What are the potential side effects?
Potential side effects may include reactions related to immune system activation such as flu-like symptoms from PEG-IFN; gastrointestinal issues; fatigue; possible changes in blood counts or liver enzymes due to the various drugs being tested.

Experimental Treatment
Active Control
Group I: siRNA(RO7445482)+ Programmed Death Ligand-1 Locked Nucleic Acid (PD-L1 LNA; RO7191863) + NUC [1]Experimental Treatment3 Interventions
Participants will receive RO7445482 (Dose 2) during Weeks 1-24 and RO7191863 (Dose 1) will be administered during Weeks 13-24, in addition to their background NUC therapy for the 24-week treatment period. At the end of the treatment period, participants will continue NUC treatment during the follow-up unless the NUC discontinuation criteria have been met.
Group II: siRNA (RO7445482) + TLR7 (RO7020531) + NUCExperimental Treatment3 Interventions
Participants will receive RO7445482 (Dose 2) in addition to their background NUC therapy for the 48-week treatment period. RO7020531 (150 mg QOD) will be administered during Weeks 13-24 and Weeks 37-48 (i.e., 2 treatment cycles of 12 weeks' duration each and 42 doses of RO7020531 for each cycle). At the end of the treatment period, participants will continue NUC treatment during the follow-up unless the NUC discontinuation criteria have been met.
Group III: siRNA (RO7445482) + Pegylated Interferon (PEG-IFN) + NUCExperimental Treatment3 Interventions
Participants will receive RO7445482 (Dose 2) in addition to their background NUC therapy for the 48-week treatment period. PEG-IFN will be administered at a dose of 180 μg once weekly (QW) for 48 weeks. At the end of the treatment period, participants will continue NUC treatment during the follow-up unless the NUC discontinuation criteria have been met.
Group IV: siRNA (RO7445482) + PD-L1 LNA (RO7191863) + NUC [2]Experimental Treatment3 Interventions
Participants will receive RO7445482 (Dose 2) during Weeks 1-24 and RO7191863 (Dose 1) will be administered during Weeks 25-36, in addition to their background NUC therapy for the 36-week treatment period. At the end of the treatment period, participants will continue NUC treatment during the follow-up unless the NUC discontinuation criteria have been met.
Group V: siRNA (RO7445482) + CpAM (RO7049389) + NUCExperimental Treatment3 Interventions
Participants will receive RO7445482 (Dose 2) and RO7049389 (600 mg QD) in addition to their background NUC therapy for the 48-week treatment period. At the end of the treatment period, participants will continue NUC treatment during the follow-up unless the NUC discontinuation criteria have been met.
Group VI: siRNA (RO7445482) (Dose 2) + NUCExperimental Treatment2 Interventions
Participants will receive RO7445482 (Dose 2) in addition to their background NUC therapy for the 48-week treatment period. At the end of the treatment period, participants will continue NUC treatment during the follow-up unless the NUC discontinuation criteria have been met.
Group VII: Short Interfering Ribonucleic acid (siRNA; RO7445482) (Dose1) + NUCExperimental Treatment2 Interventions
Participants will receive RO7445482 (Dose 1) in addition to their background NUC therapy for the 48-week treatment period. At the end of the treatment period, participants will continue NUC treatment during the follow-up unless the NUC discontinuation criteria have been met.
Group VIII: Core Protein Allosteric Modulator (CpAM; RO7049389) + Toll-like Receptor 7 (TLR7;RO7020531) + NUCExperimental Treatment3 Interventions
Participants will receive RO7049389 (600 mg once daily [QD]) in addition to their background NUC therapy for the 48-week treatment period. RO7020531 (150 mg once every other day [QOD]) will be administered during Weeks 1-12 and Weeks 25-36. At the end of the treatment period, participants will continue NUC treatment during the follow-up unless the NUC discontinuation criteria have been met.
Group IX: Nucleos(t)ide (NUC) Control ArmActive Control1 Intervention
Participants will continue their background NUC therapy for the 48-week treatment period. At the end of the treatment period, in line with current CHB treatment guidelines, participants will continue NUC treatment during the follow-up unless the NUC discontinuation criteria have been met.
