UCD outcomes can remain suboptimal, and morbidity can remain high1-3

Additional management options are clearly needed2,4

Available UCD treatment options are considered effective for managing ammonia, yet outcomes do not always reflect this.1 Lack of adherence due to various factors—including dosing regimens, tolerability issues, forgetting to take doses—continues to contribute to dangerous elevations in ammonia.2,4

A 17-member panel of metabolic, pediatric, and dietetic experts has indicated that addressing survival, cognitive, neurologic, and quality-of-life outcomes is critical when making decisions regarding UCD management.4 Improving clinical outcomes is a focus of continued research.3

As UCD research continues, additional treatment options that reduce adherence challenges may lead
to improved clinical outcomes in UCDs.3,5
