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

Our multidisciplinary team brings together experts who accelerate the journey from discovery to clinic.
Sferogen was established in 2022 as a spin-off 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 developed innovative purification steps to yield highly pure virus-like particles with the intended morphology. Preclinical studies in a mouse model showed an immune response comparable to that of approved vaccines.
nanoSFERIC
We have developed an innovative recombinant nanoSFERICTM platform that has a number of key features, including a modular design, fast antigen switching, and scalable production. In a preclinical model, our lead vaccine candidate demonstrated a strong immune response after single dose.
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 witness paradigm shifts in our understanding
of immune system and systems 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 indentify patient-specific characteristics in oncology will
exponentially expand the area of personalized medicine. This will bring together
the multiple layers of knowledge and expertise within a One Health apprach.
We are looking for innovative talents in research, biotechnology, clinical
medicine, and regulatory affairs to help us achieve our ambitious goals.
