Engineering personalized
neoantigen vaccine
revolution
nanoSFERICTM technology combines advances in protein science, data science, and manufacturing to make personalized cancer vaccines more accessible. It also enables doctors and researchers to test and refine treatments more rapidly than ever before. Ultimately, nanoSFERICTM aims to bring powerful, individualized immunotherapy to more patients worldwide.
We developed nanoSFERIC, a proprietary self-assembling protein nanoparticle platform with superior immunogenicity
The assembled nanoSFERIC particles form immunogenic rings with repeating target epitopes in eukaryotic and prokaryotic expression systems.
The planar presentation of repeating epitopes to B cells augments cross-linking of the immune receptors, boosting cell activation and specific antibody production.

In our team, experts from diverse fields have joined forces to accelerate the journey from discovery to clinic.
Sferogen was established in 2022 as a spin-off company from COBIK, a research and development organization in the field of biotechnology.
eVLP
We developed an enveloped virus-like particle (eVLP) lead COVID-19 vaccine candidate, nSfCoVac, using a high-throughput insect cell line. This vaccine consists of three main SARS-CoV-2 structural proteins. We introduced innovative purification steps to yield pure virus-like particles with the desired morphology. Preclinical studies on a mouse model proved the immunogenicity on par with approved vaccines.
nanoSFERIC
We developed an innovative recombinant nanoSFERIC platform that has a number of key features, including a modular design, fast antigen switching, and scalable production. Our lead vaccine candidate demonstrated a strong immune response after single dose in a preclinical model antibody response.
Work with us
Our aim is to turn most innovative ideas into reality. That is why
we are constantly challenging concepts, seeking new ideas and
looking for bold, pioneering partners.
We believe that next decade will wittnes paradigm shifts in our understanding
of immune system and system biology. This, in concert with current
pace of innovation in biotechnology will enable the design of novel,
better and safer vaccines for global health. On the other side, our
ability to recognize and tackle personalized traits in oncology will
exponentially expand the area of personalized medicine. This will result
in bringing together the multiple layers of current knowledge and expertise
into a One Health.
We are looking for innovative talents in research, biotechnology, clinical
medicine and regulation to help us achieve our abitious goals.
