NCT01828463

Brief Summary

SONIA 1 is an international, multicentre, randomised, open-label, no-treatment controlled, parallel group, dose-response study to investigate the effect of once daily nitisinone on 24-hour urinary homogentisic acid excretion in patients with alkaptonuria after 4-weeks treatment. They study will identify the optimal dose to decrease urine homogentisic acid to near normal levels.
