City Therapeutics

Develops RNAi therapeutics using trigger molecules

Overview

City Therapeutics develops RNA interference (RNAi) medicines. It works on creating next-generation trigger molecules and delivery ligands to silence disease-causing genes in the body. The core product approach uses RNAi to turn off specific genes in cells, reducing the production of harmful proteins. Delivery and targeting are tailored, so the RNAi triggers reach the right tissues more effectively than before. Compared with peers, City Therapeutics emphasizes proprietary trigger chemistry and ligand-based delivery to improve precision and expand the range of diseases that can be treated, aiming for strong therapeutic impact rather than relying on traditional small molecules or antibodies. The company’s goal is to advance and apply RNAi-based medicines across multiple conditions by leveraging human genetics insights, partnerships, and focused development to bring effective gene-silencing therapies to patients.
