A new treatment approach for phenylketonuria (PKU).

Official title: LEAD PROJECT 1: PHENYLKETONURIA (PKU)

Funded at Children's Hosp of Philadelphia · NIH-10896260 · Data updated 2026-11-12

This study is working on a new treatment for people with phenylketonuria (PKU) who have a specific gene mutation, aiming to make managing the condition easier and safer than current methods, and they hope to start testing it in patients soon.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals diagnosed with phenylketonuria who carry the c.842C>T (P281L) mutation.

Less likely to help

Patients with phenylketonuria who do not have the specific c.842C>T (P281L) mutation may not benefit from this research.

What this research studies

This research focuses on developing a lipid nanoparticle-based treatment for phenylketonuria (PKU), a genetic disorder that leads to harmful levels of phenylalanine in the body. Specifically, it targets patients with the c.842C>T (P281L) mutation in the PAH gene, which is known to be treatable through adenine base editing. The study aims to overcome the limitations of current treatments, such as strict dietary restrictions and injectable therapies that carry risks of severe allergic reactions. By the end of the funding period, the researchers plan to file an Investigational New Drug (IND) application and initiate a clinical trial to evaluate the safety and efficacy of this new treatment.

Why it matters

Potential benefit: If successful, this research could provide a more effective and safer treatment option for patients with PKU, reducing reliance on restrictive diets and injectable therapies.

How similar studies have gone: Previous research has shown promise in using gene editing techniques for genetic disorders, indicating potential success for this novel approach.
