Official title
A Phase 1, Randomized, Placebo- and Active-controlled Crossover Study to Evaluate the Effects of Sapropterin Dihydrochloride Oral Administration on QTc Intervals in Healthy Adult Subjects
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Sapropterin dihydrochloride (subsequently referred to as sapropterin) (Kuvan®) was approved by the FDA for the treatment of hyperphenylalaninemia in 2007. Preclinical and clinical studies and post-marketing surveillance have not demonstrated any specific cardiovascular concerns with sapropterin (Kuvan®). Nonetheless, nonantiarrhythmic drugs may have the potential to prolong QT interval, leading to potentially fatal ventricular tachycardias, including torsades de pointes. As part of the post-marketing commitment, a thorough QT/QTc study will be conducted according to ICH guidelines.
