LEXINGTON, Mass., June 10, 2022 (GLOBE NEWSWIRE) -- Agenus Inc. (NASDAQ: AGEN), an immuno-oncology company with an extensive pipeline of therapies and adjuvants designed to activate the immune response to cancer and infections, today shared that partner GSK announced positive headline results from a pre-specified efficacy interim analysis of the AReSVi 006 phase III trial evaluating their investigational RSV vaccine in adults aged 60 years and above. The primary endpoint was exceeded with no unexpected safety concerns observed. Engagement with regulators is planned to start immediately with anticipated regulatory submissions in H2 2022.
“The need for vaccines offering long-lasting efficacy and scalable production processes has been amplified by the current pandemic. The effectiveness and durability of vaccines containing QS-21 STIMULON has been demonstrated in Shingrix, with best-in-class protection exceeding 9 years. Our subsidiary, SaponiQx, is developing a proprietary plant cell culture manufacturing process designed to enable broader use of QS-21 STIMULON through a sustainable, eco-friendly production method scalable to address pandemic and other vaccine needs,” said Dr. Garo H. Armen, Chief Executive Officer of Agenus Inc.
GSK’s RSV vaccine candidate contains Agenus’ proprietary QS-21 STIMULON within its AS01 adjuvant, which – in the context of other antigens – has already demonstrated positive immune responses as well as a favorable safety profile. QS-21 STIMULON is a critical component of the AS01 adjuvant used in multiple GSK vaccines, including GSK’s FDA approved Shingrix shingles vaccine, and the world’s first malaria vaccine Mosquirix, endorsed by the WHO.1,2
Agenus’ subsidiary, SaponiQx, has developed a plant cell culture method of manufacturing QS-21 STIMULON, which is designed to support its broader use based on sustainable, scalable, and cost-effective supply. SaponiQx expects to generate GMP material using this process before the end of the year to enable partner clinical trials. Once SaponiQx’s plant cell culture process is fully scaled, Agenus’ wholly-owned manufacturing campus is designed to support the capacity for broad use across disease settings, as well as scalability to address future pandemic threats.
