ISR Vaccine AB signs contract with Oncovir Inc for the adjuvant to the vaccine
ISR Vaccine AB has today signed a contract with the US company Oncovir Inc. for the rights to
use their adjuvant Hiltonol in the SARS-CoV-2 vaccine, and their assistance to carry out tech
transfer to CMO company for large scale GMP production.
”The well-used adjuvant from Oncovir fits nicely with our vaccine formulation, which together
with full length spike mimics the natural SARS-CoV-2 infection with induction of antibodies and
a strong T cell response. In our preclinical studies we have been very impressed by the
stimulatory direction of the adjuvant and with the lack of side effects in the doses used in
respiratory tract administration”, comments Ola Winqvist, CEO ISR.
With the signing with Oncovir, ISR has secured another key component and their large scale
production in preparation for the phase III clinical trial and for the market phase. The nasal
inhalation vaccination uses natural spike protein, the addition of an adjuvant in a formulation
presented for the immune system in the respiratory tracts which induces a strong local mucosal
immune response.
“We see excellent potential with the combination of Poly-ICLC and ISRs spike protein to
address the ongoing SARS-CoV2 pandemic. ISR has a great team, and we are looking
forward to this collaboration”, comment Andres M. Salazar, CEO of Oncovir
