Safety, tolerability, pharmacokinetics, and efficacy of kukoamine B in patients with sepsis: A randomized phase IIa trial.

Purpose: To evaluate the safety, tolerability, pharmacokinetics, and efficacy of kukoamine B (KB), an alkaloid compound with high affinity for both lipopolysaccharide (LPS) and oligodeoxynucle-otides containing CpG motifs (CpG DNA), in patients with sepsis-induced organ failure.

Materials And Methods: This was a multicenter, randomized, double-blind, placebo-controlled phase IIa trial. Patients with sepsis-induced organ failure were randomized to receive either KB (0.

Pharmacokinetics and safety evaluation of oral Palonosetron in Chinese healthy volunteers: A phase 1, open-label, randomized, cross-over study.

Purpose: Palonosetron hydrochloride is a specific 5-HT3 receptor antagonist, used to prevent chemotherapy-induced nausea and vomiting (CINV), and is a known chemical entity currently registered in the oral and IV forms in several countries worldwide.

Methods: Single-center, single-dose, 3-treatment, open-label, randomized, 3-period, phase-I cross-over study, conducted in 18 individuals (16 males and 2 females). The primary objective was to assess the pharmacokinetic profile of Palonosetron 0.

Pharmacokinetics analysis based on target-mediated drug distribution for RC18, a novel BLyS/APRIL fusion protein to treat systemic lupus erythematosus and rheumatoid arthritis.

Background And Purpose: RC18 is a novel recombinant fusion protein targeting on B lymphocyte stimulator (BLyS). We aimed to develop and qualify a population pharmacokinetics (PopPK) model for RC18 in systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) patients, taking into account the mechanistic target-mediated drug disposition (TMDD) process.

Methods: A TMDD model of RC18 was developed using data from two phase I clinical trial (n = 23).

Translational prediction of first-in-human pharmacokinetics and pharmacodynamics of janagliflozin, a selective SGLT2 inhibitor, using allometric scaling, dedrick and PK/PD modeling methods.

Aim: Janagliflozin is an orally selective SGLT2 inhibitor. To predict human pharmacokinetics/pharmacodynamics (PK/PD) characteristics of janagliflozin. To design optimal starting dose and effective dose for janagliflozin first-in-human (FIH) study.

A population pharmacokinetic study to accelerate early phase clinical development for a novel drug, teriflunomide sodium, to treat systemic lupus erythematosus.

Purpose: To accelerate early phase clinical development of a novel drug, teriflunomide sodium, to treat systemic lupus erythematosus (SLE) based on the data of leflunomide.

Methods: Based on a pharmacokinetic (PK) study assessing the relative bioavailability of teriflunomide sodium compared to leflunomide, a population pharmacokinetic (Pop PK) analysis was firstly conducted using non-linear mixed effect model. Covariates were thoughtfully screened after Pop PK model evaluation and qualification using various diagnostic plots, visual predicted check (VPC) and bootstrap method.

A high-performance liquid chromatography-tandem mass spectrometry method for the determination of lifrafenib, a novel RAF kinase and EGFR inhibitor, in human plasma and urine and its application in clinical pharmacokinetic study.

Lifirafenib (BGB-283), a dual inhibitor trageting BRAF kinase and EGFR, showed favorable efficacy and safety in treating patients with different cancer types harboring mutations in BRAF, KRAS and NRAS. In order to support the clinical pharmacokinetic study, a sensitive high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method was developed and validated to quantify lifirafenib concentration in human plasma and urine. Plasma samples were purified using protein precipitation.

Metabolites characterization of a novel DPP-4 inhibitor, imigliptin in humans and rats using ultra-high performance liquid chromatography coupled with synapt high-resolution mass spectrometry.

Imigliptin has been reported as a novel dipeptidyl-peptidase-IV (DPP-4) inhibitor to treat type 2 Diabetes Mellitus (T2DM), and is currently being tested in clinical trials. In the first human clinical study, imigliptin was well tolerated and proved to be a potent DPP-4 inhibitor. Considering its potential therapeutic benefits and promising future, it is of great importance to study the metabolite profiles in the early stage of drug development.

Simultaneous determination of TPN729 and its five metabolites in human plasma and urine by liquid chromatography coupled to tandem mass spectrometry.

A specific and sensitive method was firstly developed using high performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS) to simultaneously quantify TPN729 and its metabolites (TPN729-D1, TPN729-D2, TPN729M15-3 and TPN729M3) in human plasma and (TPN729-D1, TPN729-D2, TPN729M15-3 and TPN729M14) in human urine. Protein precipitation and direct dilution were used to extract TPN729 and its metabolites from plasma and urine, respectively. Ionization of TPN729, TPN729-D1, TPN729-D2, TPN729M15-3, TPN729M3, TPN729M14 and sildenafil (internal standard, IS) was performed using an electrospray ionization (ESI) source in positive mode and detection was carried out with multiple reaction monitoring (MRM) mode.
