Additional Dietary Large Neutral Amino Acids (LNAA) for Improved Symptoms in Adult Classical Phenylktonuria (PKU)
NCT05174559 · Status: ACTIVE_NOT_RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 10
Last updated 2023-12-04
Summary
This research investigates the effects of combining a phenylalanine restricted diet (usual care) with LNAA supplementation (adjuvant LNAA) in well-controlled adults with classical PKU. The hypothesis is that symptoms are improved in well-controlled patients who receive adjuvant LNAA therapy compared with diet monotherapy. Six symptomatic classical PKU adults will be enrolled to test the hypothesis in a small series of N-of-1 randomized controlled trials over 18-weeks. All assessments will be collected in patient's homes. A 3-month follow-up period will assess the longer-term effects of adjuvant LNAA in patients who show clinical benefit at the end of the intervention period.
