Testing the Drug JNT-517 in People with Phenylketonuria

(IRB#: IRB_00189870)

Phenylketonuria (PKU) is a condition in which a persons body does not break down an amino acid called phenylalanine. People with PKU must follow a special diet limiting the amount of protein they eat. This study will test a drug called JNT-517 to treat people with this disease. The study wants to see if the drug will help people with the disease and is safe. Being in the study requires attending in person visits at the study clinic with an option for a couple home visits over about 9 to 13 weeks. Participants will keep a diet diary. Medical tests will be done during the study to track the health of participants.
