A once-daily dose of tofogliflozin for 12 weeks was an effective, safe and well-tolerated treatment for T2DM.

Abstract:Inclacumab, a novel monoclonal antibody against P-selectin in development for the treatment and prevention of atherosclerotic cardiovascular diseases, was administered in an ascending single-dose study as intravenous infusion to evaluate safety, pharmacokinetics, and pharmacodynamics. Fifty-six healthy subjects were enrolled in this randomized, double-blind placebo-controlled study. Each dose level (0.03–20 mg/kg) was investigated in separate groups of 8 subjects (6 on inclacumab, 2 on placebo). Platelet–leukocyte aggregates, free/total soluble P-selectin concentration ratio, drug concentrations, bleeding time, platelet aggregation, antibody formation, and routine laboratory parameters were measured frequently until 32 weeks. Pharmacokinetic profiles were indicative of target-mediated drug disposition. Platelet–leukocyte aggregate inhibition and soluble P-selectin occupancy showed dose dependency and were strongly correlated to inclacumab plasma concentrations, with IC50 of 740 and 4600 ng/mL, respectively. Inclacumab was well tolerated by the majority of subjects and did neither affect bleeding time nor platelet aggregation. These findings allowed the investigation of the potential beneficial therapeutic use of inclacumab in patient study.

To enable early detection of DIN and to ensure patients' safety through appropriate risk minimization and mitigation strategies, future research should focus on identification and validation of novel predictive biomarkers of kidney injury and development of DIN-specific classification and staging system. This could help in reducing the current high rate of attrition during drug development, and reduce marketing and post-marketing withdrawals of nephrotoxic drugs.

This study investigated the safety, pharmacokinetics, and pharmacodynamics of single oral doses of R1663, a factor Xa inhibitor, in healthy volunteers. It was a single-blind, randomized, crossover, placebo-controlled, dose escalation study in 33 healthy male volunteers aged 18 to 45 years. Each volunteer was dosed on 3 occasions with R1663 or placebo. Single oral doses of R1663 were safe and well tolerated. R1663 did not affect bleeding time. Pharmacodynamic effects (prothrombin time [PT], activated partial thromboplastin time [aPTT]), parameters of thrombogram, and anti-factor Xa activity) and plasma concentrations of R1663 were dose-dependent and showed low to moderate (<40%) intersubject and intrasubject variability. Maximum factor Xa inhibition was achieved 3 hours post dose (time to maximum concentration of R1663): clotting times were prolonged up to 2.5-fold, whereas endogenous thrombin potential (ETP) and peak height were decreased by 48% and 85% from their baseline values, respectively. Pharmacodynamic parameters were strongly correlated to R1663 plasma concentrations, with IC50 values of 182 and 2680 ng/mL for peak height and ETP, respectively. Oral doses of R1663 up to 480 mg were well tolerated, with predictable pharmacodynamics and pharmacokinetics. R1663 prolonged clotting times (PT, aPTT) and inhibited thrombin generation without increasing bleeding time.

These findings will allow the administration of R1663 without regard to food in the upcoming trials.

This study investigated the safety, pharmacokinetics and pharmacodynamics of multiple oral doses of R1663, a factor Xa inhibitor, and explored the influence of age and gender on pharmacokinetics and pharmacodynamics of R1663. This was a single-blind, randomised, placebo-controlled, dose escalation study in 48 healthy male volunteers aged 18 to 44 years. R1663 doses up to 300 mg twice daily or 400 mg once daily were administered for seven days. The exploration of gender and age effect was carried out in separate cohorts of eight male and eight female volunteers aged 45 to 65 years. Multiple oral doses of R1663 were safe and well tolerated. Pharmacokinetics was linear and showed moderate variability. Plasma concentrations peaked at 3 hour. Terminal half-life at steady state was 3-5 hours. Accumulation of R1663 was minimal. R1663 prolonged clotting times, inhibited thrombin generation (peak height and endogenous thrombin potential [ETP]) and anti-factor Xa activity in a concentration-dependent manner without increasing bleeding time. Pharmacodynamic parameters were strongly correlated to R1663 plasma concentrations. The inhibition was more pronounced on peak height (IC₅₀ = 194 ng/ml) than on ETP (2790 ng/ml). Pharmacokinetics and pharmacodynamics of R1663 appeared not to be substantially affected by age or gender but remained to be confirmed in larger clinical trials including older patients. Meanwhile, dose adjustments based on age and gender are not anticipated.
