Eligibility Criteria:
Key Inclusion Criteria:
* Diagnosis of PKU, defined as documented presence of 2 mutant alleles in the phenylalanine hydroxylase (PAH) gene, of which at least 1 is the R408W mutation, as determined during Screening per the genotyping performed by the study central genotyping laboratory.
* At least 1 plasma Phe concentration greater than (\>) 600 micromoles per liter (μmol/L) in the 52 weeks before providing informed consent.
* Average concentration of plasma Phe \> 600 μmol/L in Phe samples taken during Screening, with no individual assessment below 360 μmol/L. Any Phe samples taken after Day -20 will not be included.
* Body mass index (BMI) greater than or equal to (≥) 18.0 kilograms per meter square (kg/m\^2) to lesser than or equal to (≤) 35.0 kg/m\^2 and weight ≥ 50 kilograms (kg) at any time during the Screening Period.
* Documented approval from a dietitian confirming that the subject can maintain their diet consistent in protein and Phe intake throughout the study as outlined in the Diet Manual.
Key Exclusion Criteria:
* Prior exposure to AG-181.
* Receiving inhibitors of P-glycoprotein (P-gp) that have not been stopped for ≥ 5 days or a timeframe equivalent to 5 half-lives (whichever is longer) before administration of the first dose of study drug.
* Receiving products that are strong inhibitors or strong inducers of cytochrome P450 CYP1A2, CYP2C8, or CYP3A that have not been stopped for ≥ 28 days before administration of the first dose of study drug.
* Receiving treatment with an acid-reducing agent, including but not limited to proton pump inhibitors and H2 blockers. Short-acting acid-reducing agents such as calcium carbonate are permitted.
* Any preexisting condition that could (in the opinion of the Investigator) interfere with gastrointestinal anatomy or motility that may disrupt the absorption, metabolism, and/or excretion of the study drug.
* Any preexisting condition that could (in the opinion of the Investigator) interfere with hepatic or renal function that may disrupt the absorption, metabolism, and/or excretion of the study drug.
* Inability to tolerate oral medication.
* Unwillingness to washout from tetrahydrobiopterin (BH4) supplementation (eg, sapropterin dihydrochloride, Kuvan), pegvaliase-pqpz (Palynziq), or any other PKU therapy by Day -30 during Screening.
