Etherna Manufacturing

Press information

eTheRNA Manufacturing builds on more than 30 years of manufacturing research grade mRNA, and more than 5 years of GMP mRNA production. Following our foundation at the labs of the VUB in Brussels, since 2018 all RNA production is performed in our GMP approved facility in Niel, Belgium.

As an experienced RNA CDMO we now offer our expertise and capabilities as a one stop service to bring your RNA- based research and products from the lab to the clinic.

eTheRNA LNPs for intravenous delivery of mRNA have been show to exert first-in-class immune T-cell-specific responses in preclinical experiments. The induced immune responses are multifunctional and boostable. These premium results was achieved by optimizing the composition of the LNPs and designing them to target the spleen and not mainly the liver.

Generally speaking, R&D grade RNA can be ordered from amounts as small as 1mg up to gram amounts. GMP grade production usually starts at higher quantities, preferably starting at around 100mg up to gram range. Very small or very large batches may restrict the options for purification.

eTheRNA distinguishes itself from competitors on different levels:

  • Our general vaccine mRNA platform is unique as it uses our proprietary TriMix, a potent T-cell vaccine adjuvant, in combination with eTheRNA’s proprietary LNPs induces first-in-class vaccine-specific immune responses.
  • eTheRNA is the only clinical-stage mRNA company developing an intranasal mRNA vaccine platform. This platform is aimed to induce mucosal T cell immunity which is key to prevent lower respiratory tract infections.
  • Whereas competitors focus on short-lived antibody responses with limited cross reactivity in the development of their SARS-CoV-2 vaccine, eTheRNA is developing a vaccine with a long-lived T cell response and significant cross reactivity.
  • We are developing mRNA-based products mimicking the action of oncolytic viruses. This modality offers opportunities to develop products with cell-lytic, tumor microenvironment modifying and immune stimulating properties without the disadvantages of oncolytic viruses.
