  • Six months put up the booster vaccination with ABNCoV2, the neutralization antibody titers in opposition to Wuhan and the Omicron variant remained excessive and at ranges related to a larger than 90% efficacy.

COPENHAGEN, Denmark, October 17, 2022 – Bavarian Nordic A/S (OMX: BAVA) introduced as we speak the outcomes of a six-month follow-up evaluation from a Phase 2 medical trial of ABNCoV2, a VLP-based, non-adjuvanted COVID-19 booster vaccine candidate.

Previously reported outcomes from the trial confirmed, that vaccination with 100ug ABNCoV2 in 103 seropositive topics was capable of show a robust boosting impact, growing the prevailing ranges of SARS-CoV-2 neutralizing antibodies in opposition to each the Wuhan variant and variants of concern (Alpha, Beta, Delta and Omicron) to ranges reported to be extremely efficacious (>90%) in opposition to SARS-CoV-21.

A cohort of 41 topics have been adopted for six months put up vaccination. From this cohort, two topics with confirmed COVID-19 illness have been excluded from the immune evaluation. Six months put up vaccination, neutralization titers have been six occasions greater than pre-boost titers in opposition to Wuhan and practically 10 occasions greater than the pre-boost titers for Omicron BA.1. This represented lower than a 50% decline within the peak neutralizing titers after six months and in comparison with the information printed for mRNA vaccines2,3,4, the antibody decay seems much less sharp, indicating a probably longer length of safety throughout variants of concern.

Paul Chaplin, President and CEO of Bavarian Nordic mentioned: “It is highly encouraging that the strong booster responses we have reported for ABNCoV2 against all variants of concern are maintained after six months post vaccination at levels associated with a high degree of efficacy. These latest data further support the concept that ABNCoV2 could be a universal booster vaccine inducing strong and durable immune responses against all major variants of concern, including Omicron, without the need to modify the vaccine. We look forward to generating further data in the ongoing Phase 3 trial that will shortly open sites in Denmark.”

About ABNCoV2
ABNCoV2 is a next-generation COVID-19 vaccine candidate, initially developed by AdaptVac, Denmark, utilizing their proprietary capsid virus like particle (cVLP) expertise. Bavarian Nordic has licensed the worldwide commercialization rights to the vaccine and has assumed the accountability for additional medical growth in the direction of licensure.

ABNCoV2 has proven to be extremely immunogenic in related preclinical fashions inducing a sturdy and extremely protecting response from a COVID-19 problem. Results from a Phase 2 trial in beforehand vaccinated topics has confirmed the flexibility of ABNCoV2 to considerably enhance antibody titers to ranges reported to be extremely efficacious (>90%) in opposition to SARS-CoV-2, together with variants of concern.

A worldwide Phase 3 trial assessing the non-inferiority of ABNCoV2 in comparison with Comirnaty® when it comes to neutralizing antibodies in opposition to the SARS-CoV-2 index virus was initiated in September 2022. The double-blind, managed trial will enroll two teams of a complete of roughly 4,000 grownup topics who both beforehand accomplished main vaccination or have already obtained one booster dose of a licensed COVID-19 vaccine. The first group, which is presently enrolling within the U.S., will consider the security and tolerability of the vaccine in 3,000 topics receiving a single 100 µg dose of ABNCoV2. The second group will begin enrollment of 1,000 topics in Denmark and Belgium later in October. Subjects on this group shall be randomized to obtain both a single 100 µg dose of ABNCoV2, or a single 30 µg grownup booster dose of Comirnaty.
