Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Safety, pharmacokinetics, and pharmacodynamics of NPI-001 oral solution in cystinosis patients compared with cysteamine.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will examine the safety, pharmacokinetics, and pharmacodynamics of NPI-001 oral solution in cystinosis patients, aged ≥ 10 years. The ability of NPI-001 to reduce cystine will be assessed and compared with cysteamine.
