About Cullgen Inc.:

Cullgen is a privately held clinical-stage biopharmaceutical company dedicated to the development of first-in-class new chemical entities (NCEs) for the treatment of diseases lacking effective therapeutic approaches. The company applies its proprietary uSMITEtm (ubiquitin-mediated, small molecule -induced target elimination) platform to expand the drug design paradigm beyond functional site inhibition, enabling the targeting of historically "undruggable" proteins for selective destruction. Leveraging years of work by its founders on the proteasome system and key discoveries regarding its functionality, Cullgen has successfully generated multiple highly potent, selective, and bioavailable targeted protein degrader compounds that utilize proprietary novel E3 ligands.
