A number of drug developers have been stung in their attempts to chase the STING pathway.
It may have become a household name during the pandemic, but the drumbeat oSTINGouncements from BioNTech this year are a reminder that the German company has far more varied ambitions. With infectious disease and cancer vaccines in various stages of development, the biotech has now licensed a variety of small-molecule programs from Poland’s Ryvu Therapeutics.
Under the multi-target agreement, BioNtech will pay Ryvu 20 million euros ($20.7 million) upfront along with an equity investment of the same amount. Split into two parts, one side of the deal will see BioNTech secancern exclusive global license to develop and commercialize Ryvu’s STING agonist portfolio as standalone small molecules, includRyvu Therapeuticsies and in combination with other therapies.

BioNTecholecules targeting novel immune signaling pathways have a great potential to increase the efficacy of cancer immunotherapies,” said BioNTech CEO Ugur Sahin, M.D., in a Nov. 30 release. “The collaboration with Ryvu provides us with the opportunity to complement our immunotherapy pipeline with a portfolio of potent immunomodulatory molecules.”
BioNTech’s oncology pipeline is already well underway. The company has 19 candidates across a total of 24 clincancerrials, including CAR-T cBioNTechapy candidate BNT211. The furthest developed are phase 2 trials of melanoma vaccine BNT111 and BNT113 for HPV16-positive cancers—which both use the biotech’s FixVac platform—plus a pancreatic cancer hopeful called autogene cevumeran and the bispecific antibody immune checkpoint modulator BNT311.
