About Sephience™ and Its Mechanism
Sephience™ is specifically indicated for the treatment of both adult and pediatric patients diagnosed with phenylketonuria (PKU). This drug functions as a natural precursor to the enzymatic co-factor BH4, which is crucial for the enzyme phenylalanine hydroxylase (PAH). Its mechanism effectively reduces blood phenylalanine (Phe) levels, providing a treatment option for a diverse patient population.
- Approval Status: Sephience is approved in the European Union, United States, and now Japan.
- Target Condition: Phenylketonuria (PKU)
- Patient Population: All ages and varying severity levels of PKU
Understanding Phenylketonuria (PKU)
Phenylketonuria (PKU) is a rare inherited metabolic disorder resulting from the body's inability to metabolize the essential amino acid phenylalanine (Phe). If not properly managed, Phe levels can rise to dangerous levels, leading to severe disabilities such as intellectual disabilities and neurological issues. PKU typically presents no symptoms at birth, but without early intervention, symptoms can worsen significantly.
Globally, it is estimated that around 58,000 people are currently living with PKU, underscoring the importance of timely diagnosis through newborn screening programs.
