Brief Summary
This is an open label, multicentre study, evaluating the safety, tolerability, efficacy, compliance and acceptability of alkalising treatments at long-term in patients with cystinuria.
Detailed Description
B14CS study is an extension study which follows the B12CS-B13CS study. Patients who have participated in B12CS-B13CS Study will have the possibility to switch to B14CS Study for a long-term treatment ...
