Discovery of the development candidate N-tert-butyl nodulisporamide: a safe and efficacious once monthly oral agent for the control of fleas and ticks on companion animals.

Nodulisporic acid A (1) is a structurally complex fungal metabolite that exhibits systemic efficacy against fleas via modulation of an invertebrate specific glutamate-gated ion channel. In order to identify a nodulisporamide suitable for monthly oral dosing in dogs, a library of 335 nodulisporamides was examined in an artificial flea feeding system for intrinsic systemic potency as well as in a mouse/bedbug assay for systemic efficacy and safety. A cohort of 66 nodulisporamides were selected for evaluation in a dog/flea model; pharmacokinetic analysis correlated plasma levels with flea efficacy.

Efficacy and safety of ezetimibe/simvastatin versus simvastatin monotherapy in hypercholesterolemic patients with metabolic syndrome.

Background: The combination of ezetimibe and simvastatin (EZE/SIMVA) inhibits intestinal absorption and hepatic synthesis of cholesterol, providing significantly greater LDL-C-lowering compared to either drug alone. We examined the efficacy and safety of EZE/SIMVAin hypercholesterolemic patients with metabolic syndrome (MetS).

Methods: We evaluated pooled data from three similarly designed, randomized, doubleblinded, placebo-controlled studies in patients with primary hypercholesterolemia.

Efficacy and safety of ezetimibe/simvastatin co- administered with fenofibrate in mixed hyperlipidemic patients with metabolic syndrome.

Background: We compared the lipid-altering effects of ezetimibe/simvastatin (EZE/SIMVA) co-administered with fenofibrate (FENO) in mixed hyperlipidemic patients with (MetS) versus those without MetS.

Methods: A total of 611 patients, 20 to 79 years old, with LDL-C 130-220 mg/dL (100-180 mg/dL for patients with type 2 diabetes [T2D]), triglycerides (TG) 150-500 mg/dL, and no history of CHD or other CHD risk equivalent disease (except for T2D), were randomized in a 1:3:3:3 ratio into one of the following four treatments for 12 weeks: placebo; EZE/SIMVA 10/20 mg; FENO 160 mg; or EZE/SIMVA+FENO. MetS status was determined in 607 patients using National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria.

Comparison of the lipid-modifying efficacy and safety profiles of ezetimibe coadministered with simvastatin in older versus younger patients with primary hypercholesterolemia: a post Hoc analysis of subpopulations from three pooled clinical trials.

Background: Despite the need for effective and well-tolerated lipid-lowering therapies for primary hypercholesterolemia in older patients, there is a relative paucity of published data on such treatments in this population.

Objective: We conducted a post hoc analysis to examine the lipid-modifying efficacy and safety profile of simvastatin (SIMVA) monotherapy, and the coadministration of ezetimibe (EZE) and SIMVA (EZE/SIMVA) in older (ie, aged>or=65 years) versus younger (ie, aged<65 years) patients with primary hypercholesterolemia.

Methods: We analyzed pooled data from 3 previously published, similarly designed, randomized, double-blind, placebo-controlled studies in patients with primary hypercholesterolemia.
