We're working to advance a potential treatment option for PKU

Even with management, PKU can still affect your daily life.

Maintaining a strict lifelong diet can be difficult and frustrating. Spikes in Phe levels can lead to trouble concentrating, depression, and other problems. That's why we're working to create more options to help you better manage your PKU. Synlogic is conducting a Phase 1 clinical research study to evaluate the safety of a potential new treatment option for PKU.

Study participants receive close care and monitoring, the study drug or placebo, and tests and assessments at no cost.
