OVX836 – Universal Flu Vaccine Candidate
Facts about the
Influenza is a devastating disease, with routine global outbreaks that pose a profound threat to global health. Seasonal influenza kills hundreds of thousands of people annually and pandemic influenza can cause tens of millions of deaths as demonstrated by historic outbreaks.

emergence of a pandemic strain
within 6 months of time.
Current seasonal flu vaccines are only partially effective because they target strain-specific surface antigens, which mutate at high rates and thus change seasonally. A universal vaccine presents the highly needed opportunity to provide broad coverage across all seasonal and pandemic strains.
Osivax is creating a revolutionary universal influenza vaccine which will uniquely empower both the B-cell immune response and the T-cell immune response. Osivax will combine its best-in-class T-cell component (OVX836) with conventional flu vaccines to fully empower both arms of the immune system.
OVX836 targets the nucleoprotein (NP), a highly conserved internal antigen. Unlike surface antigens, the NP is much less likely to mutate, alleviating the need for annual vaccination updates. Osivax’ oligoDOM® technology enables the transformation of the NP into a highly immunogenic antigen to trigger powerful T-cell immune responses.
Osivax’ lead candidate has shown powerful and long-lasting systemic and local immune responses in preclinical development. In vivo, it has shown strong efficacy against both A and B strain flu viruses and an excellent safety profile in a GLP toxicology study. After successful Phase 1 and Phase 2a clinical trials, OVX836 is currently being evaluated in two clinical trials:
- A dose-optimization Phase 2a clinical study conducted at the Center for Vaccinology of the Ghent University (CEVAC).
- A combination trial with a conventional flu vaccine at Nothern Beaches Clinical Centre in Sydney in Australia
OVX033 – Universal Coronavirus Vaccine Candidate
Facts about the
over the past 20 years
Osivax is engineering a vaccine (OVX033) that targets the virus’ nucleocapsid, an internal and invariant antigen. This target can be transformed into a highly immunogenic antigen when enabled by the oligoDOM® technology and is expected to provide universal breadth of protection against all current and future variants of SARS-COV-2 but also against future pandemic coronaviruses.
Osivax builds on the experience gained through the development of OVX836 in influenza which helped facilitate the development and drive of OVX033 to preclinical proof-of-concept in less than one year.
