Multicenter, Double-blind, Placebo-controlled Study to Evaluate the Efficacy and Safety of Fluconazole in Hypercalcicuric Patients With Increased 1.25(OH) 2D Levels

"Fluconazole 50 mg/capsule or placebo, per os during 18 weeks :~* From W0 to W2 : 1 caps/ day~* From W2 to W4 : 1 or 2 caps/day~* From W4 to W6 : 1, 2 or 3 caps/day~* From W6 to W18 : 1, 2, 3 or 4 caps/day~The number of capsules to take will be determined by 24-hours calciuria results performed every 2 weeks during the titration period (W2, W4 and W6).~During the titration period, if 24-hours calciuria is \> 0.1 mmol/kg/day, fluconazole dose will be increased every 2 weeks to 50 mg per intake, with a maximum dose of 200 mg/day. If 24-hour calciuria is ≤ 0.1mmol/kg/day, fluconazole dose will remain stable.~After W6 and until the end of the study, the treatment dose will remain stable (stable period)."
