A First-in-Patient, Multicenter, Double-Blind, 2-Arm, Placebo-Controlled, Randomized Safety and Tolerability Study of a Novel Oral Drug Candidate, CTP-499, in Chronic Kidney Disease.

The prevalence of chronic kidney disease (CKD) related to type 2 diabetes is increasing worldwide. In addition to standard of care, treatment with anti-inflammatory and antifibrotic agents such as CTP-499, a novel oral, multisubtype selective inhibitor of phosphodiesterases, may be important in CKD treatment. A phase 1b randomized, double-blind, placebo-controlled clinical trial of CTP-499 in CKD patients (25 active, 8 placebo) with an estimated glomerular filtration rate of 30-59 mL/min/1.

A Randomized Phase I Evaluation of CTP-499, a Novel Deuterium-Containing Drug Candidate for Diabetic Nephropathy.

To determine maximum tolerated dose and food effect for CTP-499, a novel agent being studied for the treatment of diabetic kidney disease. CTP-499 has demonstrated anti-inflammatory, anti-fibrotic and anti-oxidative activities in vitro as well as anti-inflammatory and renoprotective effects in a diabetic nephropathy (DN) model. Two studies were performed.

Pharmacokinetics of once-daily trospium chloride 60 mg extended release and twice-daily trospium chloride 20 mg in healthy adults.

The objective of this study is to characterize the steady-state pharmacokinetics and compare the relative bioavailability of the extended-release capsule formulation of the antimuscarinic trospium chloride, developed for once-daily administration, and trospium chloride immediate-release tablets. This is a single-center, multidose, randomized, open-label, 2-period, 2-arm crossover, bioavailability study in healthy adult male and female subjects who are within 20% of their ideal body weight. Subjects receive trospium 60-mg extended-release capsules once daily and trospium 20-mg tablets twice daily for 10 days, each in a crossover manner.

A validated patient reported measure of urinary urgency severity in overactive bladder for use in clinical trials.

Purpose: Overactive bladder (OAB) is a syndrome consisting of urinary urgency with or without urge incontinence, usually with increased urinary frequency and nocturia. In response to current limitations in OAB clinical research a new patient reported measure of urgency severity associated with OAB has been developed, namely the Indevus Urgency Severity Scale (IUSS). We report the measurement properties of the IUSS.

The overactive bladder-symptom composite score: a composite symptom score of toilet voids, urgency severity and urge urinary incontinence in patients with overactive bladder.

Purpose: To our knowledge there is no index in urology that yields a single, quantifiable and clinically interpretable measure of overactive bladder (OAB) symptoms, including urgency, 24-hour voiding frequency and urge urinary incontinence (UUI). Urgency is the most difficult of these symptoms to measure. The Indevus Urgency Severity Scale (Indevus Pharmaceuticals, Lexington, Massachusetts) was recently developed and validated to capture urgency severity per toilet void.

Shortening the NIH Stroke scale for use in the prehospital setting.

Background And Purpose: Prehospital stroke scales should identify stroke patients and measure stroke severity. The goal of this study was to identify a subset of the 15 items in the National Institutes of Health Stroke Scale (NIHSS-15) that measures stroke severity and predicts outcomes.

Methods: Using 2 distinct data sets from acute stroke clinical trials, we derived and validated shortened versions of the NIHSS (sNIHSS).
