About Sibylla Biotech
Sibylla is transforming drug discovery by targeting protein folding intermediates, a new druggable dimension in the pharmacological space. Unlike most drugs that act on native proteins, we intervene earlier-targeting proteins before they become undruggable.
Thanks to our proprietary technology platform, PPI-FIT, we can predict and target intermediate steps in the protein folding process.
Our small molecule drugs interfere with the folding process, leading to targeted protein degradation through the physiological pathway.
Sibylla is building an exciting pipeline of treatments for diseases with high medical need across multiple therapeutic areas, with the mission to bring protein folding interference therapeutics to patients.
