Efficacy, Safety and Tolerability of Everolimus in Preventing End-stage Renal Disease in Patients With Autosomal Dominant Polycystic Kidney Disease

Phase 4
Completed
Conditions
Autosomal Dominant Polycystic Kidney Disease
Interventions
Drug: Placebo
Registration Number
NCT00414440
Lead Sponsor
Novartis Pharmaceuticals
Brief Summary

This study will assess whether everolimus (RAD001) is effective in preventing cyst and kidney expansion as well as worsening of renal function in patients with ADPKD and whether the application of 5 mg/day everolimus as monotherapy is safe and well tolerated.

EverolimusEverolimusPatients in the everolimus group initially received 5 mg/day everolimus divided in 2 equal doses (i.e. 2.5 mg b.i.d.). Dose adjustments were performed to achieve a blood trough level of 3-8 ng/mL (maximum daily dose: 10 mg/day \[5 mg b.i.d.\]).
PlaceboPlaceboPlacebo tablets equivalent to the dosage of everolimus 5 mg/day, divided in 2 equal doses.
Primary Outcome Measures
NameTimeMethod
Primary Efficacy Analysis of Total Kidney Volume (mITT Set, Multiple Imputation)Baseline, Month 24

Everolimus (RAD001) compared to placebo with respect to the change from baseline in total kidney volume at Month 24.

Secondary Outcome Measures
NameTimeMethod
Course of Calculated GFR (mL/Min/1.73 m^2) From Month 24 to Month 60Months 24, 36, 48 and 60

Course of calculated GFR (mL/min/1.73 m\^2) at Months 24, 36, 48 and 60

Calculated GFR, Change From Baseline at Month 60 by Baseline cGFRMonths 24, 36, 48 and 60

Change in renal function was assessed by the estimated Glomerular Filtration Rate (eGFR) using the abbreviated (4 variables) Modification of Diet in Renal Disease (MDRD-4) formula which was developed by the MDRD Study Group and has been validated in patients with chronic kidney disease. The MDRD-4 formula used for the eGFR calculation is: eGFR (mL/min/1.73m\^2) = 186.3\*(C\^-1.154)\*(A\^-0.203)\*G\*R, where C is the serum concentration of creatinine (mg/dL), A is age (years), G=0.742 when gender is female, otherwise G=1, R=1.21 when race is black, otherwise R=1. The changes in renal function were analyzed via analysis of covariance (ANCOVA) with treatment, pre-transplant hepatitis C virus status and randomization eGFR as covariates. Based on these ANCOVA analyses, the least-squares mean and standard errors of change were reported.

Changes in Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP)Baseline, Months 12 and 24

Changes in systolic blood pressure (SBP) and diastolic blood pressure (DBP), at baseline and then months 12 and 24

Calculated GFR (mL/Min/1.73 m^2), Change From Baseline by VisitMonths 3, 6, 9, 12, 18 and 24
