Protein glycosylation is the most prevalent post-translational modification and is known to undergo profound alterations in disease. While serum N-glycosylation has been extensively studied, interstitial fluid is gaining prominence as a minimally invasive biomarker source, underscored by the widespread clinical adoption of wearable glucose monitors in diabetic patients. However, the glycomic landscape of interstitial fluid remains largely unexplored. Here, we have performed a comparative analysis of the N-glycome from interstitial fluid and matched plasma from five healthy volunteers using liquid chromatography, mass spectrometry and exoglycosidase digestions. Strikingly, the interstitial fluid N-glycome closely shows overlapping profiles with the plasma of each …

Pentobarbital is a barbiturate with sedative and anticonvulsant properties, occasionally used in pediatric patients for preoperative sedation, deep sedation during mechanical ventilation, and seizure control. Despite its long-standing clinical use, age-appropriate dosing remains challenging due to variability across studies and limited pediatric pharmacokinetic (PK) data. This study (NCT01431326) aimed to characterize the population pharmacokinetics of pentobarbital in pediatric patients (birth to 21 years) and evaluate dosing strategies using model-based simulations. A two-compartment population PK model, allometrically scaled to total body weight, adequately described pentobarbital plasma concentrations, with no additional covariates identified as significant. Simulations were conducted across four age groups: …

Despite common coadministration in nonvalvular atrial fibrillation (NVAF), there is minimal evidence regarding the impact of concomitant amiodarone use on apixaban pharmacokinetics (PK). We described the population PK of apixaban (2.5 and 5mg twice daily) in 106 hospitalized patients with and without concomitant amiodarone administration at steady state. Apixaban PK was reasonably described by a one-compartment model with first-order absorption and linear elimination. Aside from the receipt of amiodarone, age was retained as a statistically significant covariate on apparent clearance. Model-based simulations depicted concomitant amiodarone use increasing AUCT for both 2.5mg (1.58, 90% CI [1.28, 1.87]) and 5mg (1.12, 90% …

Valemetostat tosylate (valemetostat) is an oral, potent, dual inhibitor of enhancer of zeste homolog (EZH)2/1, under investigation in non-Hodgkin lymphomas (NHLs) and solid tumors. In vitro, it inhibits cytochrome P450 3A (CYP3A) and P-glycoprotein (P-gp) when combined with sensitive CYP3A or P-gp substrates. This drug–drug interaction (DDI) sub-study is part of the phase 1 trial of valemetostat monotherapy (DS3201-A-J101; NCT02732275), assessing the effect of valemetostat on the pharmacokinetics (PK) of sensitive CYP3A and P-gp substrates midazolam and digoxin, respectively, in patients with relapsed or refractory NHL, and its safety and efficacy. Patients received two simultaneous single doses of midazolam and …
