HBSAG DECLINES OBSERVED WITH VRON-0200 ALONE ARE RAPIDLY ENHANCED WITH THE ADDITION OF COMBINATION ANTIVIRAL THERAPIES: RESULTS: FROM A PHASE 1B STUDY FOR FUNCTIONAL CURE IN CHRONICALLY HBV-INFECTED PATIENTS
(AASLD 2025)
- "VRON-0200 alone, or in combination, had no observed safety concerns, and was well tolerated. Despite not targeting HBsAg, a single VRON-0200 dose was able to lower S-antigen in ~25% of pts. The combination of VRON-0200 with elebsiran and tobevibart rapidly and profoundly enhanced VRON-0200 HBsAg declines within 7 days in all pts, with further declines being observed with additional doses."

Rapid HBsAg declines and HBsAb seroconversion observed with a single dose of VRON-0200 plus Tobevibart and Elebsiran: preliminary results of a VRON-0200 combination treatment from a phase 1b study for functional cure in chronically HBV-infected patients
(EASL 2025)
- "These initial data of the combination of a single i.m. VRON-0200 dose plus Tobevibart and Elebsiran had no observed safety concerns, was well tolerated, and displayed rapid (within 7 days of the addition of Tobevibart and Elebsiran) HBsAg declines and HBsAb seroconversions in all 4 (100%) patients. These initial responses appear promising, compared to investigational combin- ation regimens, reported to date, including those containing PEG-IFN. These data, coupled with VRON-0200's safety, tolerability and ease of administration, may eventually support its use as an IFN-sparing immunotherapy, with the potential for shorter duration combination treatments for HBV functional cure."

HBsAg declines, and T cell increases, observed in CHB patients: Interim results from P1b trial of VRON-0200, a novel checkpoint modifier, following prime only, and prime and boost dosing
(EASL 2025)
- "In a CHB pt population with limited preexisting HBV immunity, VRON-0200 was safe, well tolerated, and significantly increased T cell responses and reduced HBsAg levels in >20% of patients, reflecting restored broad HBV-specific immune responses (vaccine does not contain S). VRON-0200 is a potential simple, easy-to administer, IFN-sparing immunotherapy, alone or in combination, for HBV functional cure. Immunologic, clinical, and safety analyses are ongoing."

HBsAg Declines and Immune Responses Following a Single Dose of VRON-0200: Interim Results from a Phase1B Study for HBV Functional Cure in Chronic HBV-Infected Patients
(APASL 2025)
- "A single i.m. dose of VRON-0200 was safe, well tolerated, and significantly increased T cell responses. At D91, HBsAg declines occurred in several pts even though VRON-0200 does not target S. VRON-0200 is a potential simple, easy-to administer, IFN-sparing immunotherapy, alone or in combination, for HBV functional cure. Immunologic, clinical, and safety analyses are ongoing."

Promising first-in-human, first-in-class, Phase 1B immunogenicity data of VRON-0200, a novel checkpoint modifier containing immunotherapy, for HBV functional cure
(EASL-ILC 2024)
- "As of March 15, 2024, a single, intramuscular low dose of VRON-0200 was safe, well tolerated, and, in 50% of pts, increased or induced T cell responses, to one or both peptides, even in pts without immune responses at baseline, prior to vaccination. These data support VRON-0200's continued evaluation as a potential simple, easy-to administer, interferon-sparing immunotherapy for HBV functional cure. Further immunologic and safety analyses are ongoing and will be presented."

Intrahepatic CD8+ T cells correlate with significant declines in HBV viral load and S antigen following a single vaccination with VRON-0200 in an AAV mouse model
(EASL-ILC 2023)
- "VRON-0200 is the first therapeutic vaccine to show significant correlations between intrahepatic CD8+ T cells and HBV viral loads declines. S antigen declines were also observed and directly related to HBV clearance. These data further support the key role of HBV viral load and CD8+ T cells as endpoints for HBV functional cure and highlight VRON-0200’s clinical potential alone or in combination."

[VIRTUAL] VRON-0200, A therapeutic HBV vaccine with an intrinsic checkpoint inhibitor elicits broad CD8+ T cell responses and sustained antiviral declines in preclinical studies
(EASL-ILC 2021)
- "The inclusion of gD into a therapeutic HBV vaccine enhances CD8+ T cell responses and is necessary for the observed sustained efficacy of the vaccine to reduce viral loads in the AAV8- 1.3HBV mouse model. Mice vaccinated with the gDHBV2 vector showed better viral control than those immunized with gDPolN stressing the importance of a broad-based immune response. A Phase 1b study of VRON-0200 is in planning."
