A recently granted patent (Publication Number: US11918633B2) discloses a method for reducing blood phenylalanine concentration in subjects aged 12 to 17 years old by administering a weekly dose of a formulation containing an AvPAL variant. The AvPAL variant, with specific amino acid sequences, is administered for over 50 weeks, with dosage variations ranging from 0.1 mg to 840 mg per week. The method involves induction, titration, and maintenance dosages to achieve the desired reduction in blood phenylalanine levels.

Furthermore, the patent outlines the administration frequency, duration, and dosage adjustments based on blood phenylalanine concentration. The method is specifically targeted at subjects with phenylketonuria (PKU) within the specified age range. The AvPAL variant can be pegylated and administered with stabilizers in a pharmaceutically acceptable carrier. The extension dosage, administered post-maintenance, is crucial for sustained reduction in blood phenylalanine levels. The pegylation process involves reacting the AvPAL variant with polyethylene glycol at specific ratios per lysine residue to enhance its therapeutic efficacy. Overall, the patent provides a detailed and structured approach to effectively reduce blood phenylalanine concentration in subjects with PKU, emphasizing the importance of dosage optimization and monitoring for optimal outcomes.
