Distribution, Metabolism, and Excretion of Gedatolisib in Healthy Male Volunteers After a Single Intravenous Infusion.

In this open-label study (NCT02142920), we investigated the distribution, pharmacokinetics, and metabolism of the pan-class-I isoform phosphatidylinositol 3-kinase/mammalian target of rapamycin inhibitor gedatolisib (PF-05212384), following a single intravenous administration in healthy male subjects. A single, 89-mg, intravenous dose of gedatolisib was associated with a favorable safety profile in the 6 healthy subjects evaluated. Peak plasma concentrations for unchanged gedatolisib and total radioactivity...

No Effect of Plazomicin on the Pharmacokinetics of Metformin in Healthy Subjects.

Plazomicin is an aminoglycoside that was engineered to overcome aminoglycoside-modifying enzymes, which are the most common aminoglycoside resistance mechanism in Enterobacteriaceae. Because plazomicin is predominantly eliminated via renal pathways, an in vitro study was conducted to determine whether plazomicin inhibits the organic cation transporter 2 (OCT2) and the multidrug and toxin extrusion (MATE1 and MATE2-K) transporters, using metformin as a probe substrate. Plazomicin inhibited OCT2, MATE1, and M...

Physiologically-based pharmacokinetic modelling to predict oprozomib CYP3A drug-drug interaction potential in patients with advanced malignancies.

Oprozomib is an oral, second-generation, irreversible proteasome inhibitor currently in clinical development for haematologic malignancies, including multiple myeloma and other malignancies. Oprozomib is a rare example of a small molecule drug that demonstrates cytochrome P450 (CYP) mRNA suppression. This unusual property elicits uncertainty regarding the optimal approach for predicting its drug-drug interaction (DDI) risk. The current study aims to understand DDI potential during early clinical development...

Ataluren Pharmacokinetics in Healthy Japanese and Caucasian Subjects.

To evaluate the potential for ethnicity-related differences in ataluren pharmacokinetics (PK) and safety, a phase 1 single-dose study was conducted in 48 healthy (24 Japanese and 24 Caucasian subjects), nonsmoking male volunteers who were equally divided into 3 cohorts of oral doses at 5, 10, and 20 mg/kg. Blood samples were collected until 48 hours postdose. PK results demonstrated rapid absorption of ataluren, with peak plasma levels (C ) being attained between 0.875 and 2.5 hours after dosing. The mea...

The impact of CYP2D6 mediated drug-drug interaction: a systematic review on a combination of metoprolol and paroxetine/fluoxetine.

Metoprolol (a CYP2D6 substrate) is often co-prescribed with paroxetine/fluoxetine (a CYP2D6 inhibitor) because the clinical relevance of this drug-drug interaction (DDI) is still unclear. This review aimed to systematically evaluate the available evidence and quantify the clinical impact of the DDI.

Single- and Multiple-dose Pharmacokinetics and Safety of Pimodivir, a Novel, Non-Nucleoside Polymerase Basic Protein 2 Subunit Inhibitor of the Influenza A Virus Polymerase Complex, and Interaction With Oseltamivir: A Phase 1 Open-Label Study in Healthy Volunteers.

A Drug Repurposing Method Based on Drug-Drug Interaction Networks and Using Energy Model Layouts.

Complex network representations of reported drug-drug interactions foster computational strategies that can infer pharmacological functions which, in turn, create incentives for drug repositioning. Here, we use Gephi (a platform for complex network visualization and analysis) to represent a drug-drug interaction network with drug interaction information from DrugBank 4.1. Both modularity class- and force-directed layout ForceAtlas2 are employed to generate drug clusters which correspond to nine specific dru...

Synthetic drug use and HIV infection among men who have sex with men in China: A sixteen-city, cross-sectional survey.

Increasing evidence suggests an association between synthetic drug use and HIV infection among men who have sex with men (MSM). The aim of this study was to evaluate synthetic drug use prevalence, describe characteristics of synthetic drug users, and investigate whether synthetic drug use is associated with HIV infection among Chinese MSM.

Drug-target protein interaction prediction based on AdaBoost algorithm.

The drug-target protein interaction prediction can be used for the discovery of new drug effects. Recent studies often focus on the prediction of an independent matrix filling algorithm, which apply a single algorithm to predict the drug-target protein interaction. The single-model matrix-filling algorithms have low accuracy, so it is difficult to obtain satisfactory results in the prediction of drug-target protein interaction. AdaBoost algorithm is a strong multiple classifier combination framework, which ...

TAIJI: Approaching Experimental Replicates-Level Accuracy for Drug Synergy Prediction.

Combination therapy is widely used in cancer treatment to overcome drug resistance. High-throughput drug screening is the standard approach to study the drug combination effects, yet it becomes impractical when the number of drugs under consideration is large. Therefore, accurate and fast computational tools for predicting drug synergistic effects are needed to guide experimental design for developing candidate drug pairs.

Public drug use in eight U.S. cities: Health risks and other factors associated with place of drug use.

Drug overdose is the leading cause of accidental death in the United States (U.S.). Previous studies have found that place of drug use is associated with risks including overdose, sharing of drug use equipment, and arrest, but the research on this subject in the U.S. is limited.

The ultraviolet B inflammation model: postinflammatory hyperpigmentation and validation of a reduced UVB exposure paradigm for inducing hyperalgesia in healthy subjects.

Pain models are commonly used in drug development to demonstrate analgesic activity in healthy subjects and should therefore not cause long-term adverse effects. The ultraviolet B (UVB) model is a model for inflammatory pain in which three times the minimal erythema dose (3MED) is typically applied to induce sensitisation. Based on reports of long-lasting postinflammatory hyperpigmentation (PIH) associated with 3MED, it was decided to investigate the prevalence of PIH among subjects who were previously expo...

"It's about bloody time": Perceptions of people who use drugs regarding drug law reform.

In Australia and elsewhere, the impacts of drug prohibition have sparked a critical dialogue about the state of current drug laws. While a range of 'experts' have offered their opinion and participation in these deliberations, the voices of the affected community have largely been excluded. This study aimed to gather the opinions and preferences of people who use drugs about the current or alternative models of drug laws, in addition to how they think drug laws could be changed Author Conflict of Interest D...

Sparse Modeling to Analyze Drug-Target Interaction Networks.

Most drugs produce their phenotypic effects by interacting with target proteins, and understanding the molecular features that underpin drug-target interactions is crucial when designing a novel drug. In this chapter, we introduce the protocols that have driven recent advances in sparse modeling methods for analyzing drug-target interaction networks within a chemogenomic framework. In this approach, the chemical structures of candidate drug compounds are correlated with the genomic sequences of the candidat...
