Effects of the dual peroxisome proliferator-activated receptor-?/? agonist aleglitazar on renal function in patients with stage 3 chronic kidney disease and type 2 diabetes: a Phase IIb, randomized study.

ABSTRACT: Type 2 diabetes is a major risk factor for chronic kidney disease, which substantially increases the risk of cardiovascular disease mortality. This Phase IIb safety study (AleNephro) in patients with stage 3 chronic kidney disease and type 2 diabetes, evaluated the renal effects of aleglitazar, a balanced peroxisome proliferator-activated receptor-?/? agonist.Patients were randomized to 52 weeks' double-blind treatment with aleglitazar 150 ?g/day (n=150) or pioglitazone 45 mg/day (n=152), followed by an 8-week off-treatment period. The primary endpoint was non-inferiority for the difference between aleglitazar and pioglitazone in percentage change in estimated glomerular filtration rate from baseline to end of follow-up. Secondary endpoints included change from baseline in estimated glomerular filtration rate and lipid profiles at end of treatment.Mean estimated glomerular filtration rate change from baseline to end of follow-up was -2.7% (95% confidence interval: -7.7, 2.4) with aleglitazar versus -3.4% (95% confidence interval: -8.5, 1.7) with pioglitazone, establishing non-inferiority (0.77%; 95% confidence interval: -4.5, 6.0). Aleglitazar was associated with a 15% decrease in estimated glomerular filtration rate versus 5.4% with pioglitazone at end of treatment, which plateaued to 8 weeks and was not progressive. Superior improvements in high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and triglycerides, with similar effects on glycosylated hemoglobin were observed with aleglitazar versus pioglitazone. No major safety concerns were identified.The primary endpoint in AleNephro was met, indicating that in stage 3 chronic kidney disease patients with type 2 diabetes, the decrease in estimated glomerular filtration rate after 52 weeks' treatment with aleglitazar followed by 8 weeks off-treatment was reversible and comparable (non-inferior) to pioglitazone.NCT01043029 January 5, 2010.

Project description:Rheumatoid arthritis (RA), a chronic inflammatory disease, is associated with insulin resistance. Experimental evidence indicates that the relationship between insulin resistance and inflammation is bidirectional: Inflammation promotes insulin resistance, and insulin resistance promotes inflammation. Therefore, we examined the hypothesis that pioglitazone, a thiazolidinedione peroxisome proliferator-activated receptor ? agonist, would decrease inflammation and disease activity and improve insulin resistance in patients with RA.In a single-center, randomized, double-blind, placebo-controlled crossover study patients with RA (N = 34) receiving stable therapy were randomized to also receive either pioglitazone 45 mg daily (n = 17) or matching placebo (n = 17) for eight weeks. This was followed by a four-week washout period and alternative treatment for eight weeks. Outcomes included change in Disease Activity Score in 28 joints (DAS28) score, individual components of the DAS28 score and homeostatic model assessment for insulin resistance (HOMA). Intention-to-treat analysis and linear mixed-effects models were used.Patients had a mean (± SD) age of 51 (± 14.2) years, 82.4% were female and baseline DAS28 high-sensitivity C-reactive protein (DAS28-CRP) was 4.58 (± 1.1) units. Addition of pioglitazone was associated with a 9.3% reduction (95% confidence interval (CI) = 0.17% to 17.6%) in DAS28-CRP (P = 0.046), but no significant change in DAS28 erythrocyte sedimentation rate (DAS28-ESR) (P = 0.92). There was a 10.7 mm (95% CI = 0.4 to 20.9 mm) improvement in patient-reported global health (P = 0.042), a 48.6% decrease (95% CI = 27.6% to 63.5%) in CRP (P < 0.001) and a 26.4% decrease (95% CI = 3.7% to 43.8%) in insulin resistance as measured by HOMA (P = 0.025), but no significant reduction in swollen or tender joint count or in ESR (all P > 0.05). Lower-extremity edema was more common during pioglitazone treatment (16%) than placebo (0%).Addition of pioglitazone to RA therapy improves insulin resistance and modestly reduces RA disease activity measured by DAS28-CRP and two of its components, including patient-reported global health and CRP, but not DAS28-ESR or ESR.NCT00763139.
