ArmTypeDescription
ABI-H0731 + SOC ETVEXPERIMENTALParticipants with cHBV who are currently not being treated will receive ABI-H0731 along with SOC ETV tablets orally for 24 weeks. Eligible participants may enter a separate extension study after Week 24 to continue open-label ABI-H0731 for up to an additional year if necessary.
Placebo + SOC ETVEXPERIMENTALParticipants with cHBV who are currently not being treated will receive matching placebo along with SOC ETV tablets orally for 24 weeks. Eligible participants may enter a separate extension study after Week 24 to start treatment on open-label ABI-H0731 for up to a year if necessary.
ABI-H0731 + SOC NUCEXPERIMENTALVirologically suppressed participants will receive ABI-H0731 along with SOC NUC (ETV, TDF or TAF) tablets orally for 24 weeks. Eligible participants may enter a separate extension study after Week 24 to continue open-label ABI-H0731 for up to an additional year if necessary.
Placebo + SOC NUCACTIVE_COMPARATORVirologically suppressed participants will receive matching placebo tablets and continue their SOC NUC (ETV, TDF or TAF) for 24 weeks. Eligible participants may enter a separate extension study after Week 24 to start treatment on open-label ABI-H0731 for up to a year if necessary.

Frequently asked questions about Vebicorvir

What is Vebicorvir used for?

Vebicorvir is an investigational small molecule being developed for the treatment of chronic hepatitis B, a long-term viral infection of the liver. It is in Phase 1 clinical development and is not approved for any indication. Assembly Biosciences, Inc. is the developer.

Who makes Vebicorvir?

Vebicorvir is being developed by Assembly Biosciences, Inc., which trades on the Nasdaq under the ticker ASMB. The company is the sponsor of the clinical program for this chronic hepatitis B candidate.

What phase is Vebicorvir in?

Vebicorvir is in Phase 1 clinical development. It is an investigational small molecule for chronic hepatitis B and has not been approved by the FDA. The program has completed one Phase 1 trial to date, with no active trials currently listed.

What clinical trials is Vebicorvir in?

Vebicorvir has been studied in one completed Phase 1 trial, NCT04637139, titled A Study to Evaluate the Mass Balance Absorption and AME of VBR. That trial enrolled 6 healthy male volunteers aged 18 years and older in the United States and was an uncontrolled study.

Is Vebicorvir the same as VBR?

Yes. Vebicorvir is also referred to as VBR, an abbreviation used in its clinical trial documentation. Both names refer to the same investigational small molecule being developed by Assembly Biosciences for chronic hepatitis B.
