Efficacy and safety of the histamine H receptor antagonist ZPL-3893787 in patients with atopic dermatitis.

Background: H receptor antagonists are potential novel treatments for inflammatory skin diseases, including atopic dermatitis (AD).

Objective: We sought to study the efficacy and safety of ZPL-3893787 (a selective H receptor antagonist) in patients with moderate-to-severe AD.

Methods: A randomized, double-blind, placebo-controlled, parallel-group study was conducted to evaluate ZPL-3893787 (30 mg) once-daily oral therapy in adults with moderate-to-severe AD.

Report from the fourth international consensus meeting to harmonize core outcome measures for atopic eczema/dermatitis clinical trials (HOME initiative).

This article is a report of the fourth meeting of the Harmonising Outcome Measures for Eczema (HOME) initiative held in Malmö, Sweden on 23-24 April 2015 (HOME IV). The aim of the meeting was to achieve consensus over the preferred outcome instruments for measuring patient-reported symptoms and quality of life for the HOME core outcome set for atopic eczema (AE). Following presentations, which included data from systematic reviews, consensus discussions were held in a mixture of whole group and small group discussions.

Case studies addressing human pharmacokinetic uncertainty using a combination of pharmacokinetic simulation and alternative first in human paradigms.

PF-184298 ((S)-2,3-dichloro-N-isobutyl-N-pyrrolidin-3-ylbenzamide) and PF-4776548 ((3-(4-fluoro-2-methoxy-benzyl)-7-hydroxy-8,9-dihydro-3H,7H-pyrrolo[2,3-c][1,7]naphthyridin-6-one)) are novel compounds which were selected to progress to human studies. Discordant human pharmacokinetic predictions arose from pre-clinical in vivo studies in rat and dog, and from human in vitro studies, resulting in a clearance prediction range of 3 to >20 mL min⁻¹ kg⁻¹ for PF-184298, and 5 to >20 mL min⁻¹ kg⁻¹ for PF-4776548. A package of work to investigate the discordance for PF-184298 is described.

The influence of diet upon liver function tests and serum lipids in healthy male volunteers resident in a Phase I unit.

Aim: To investigate the effect of diet upon liver function tests and serum lipids within the restricted environment of a Phase I unit.

Methods: An open randomized three-way crossover study was designed with subjects consuming three types of diet. The diets comprised, a balanced normal calorie diet, a high-carbohydrate high-calorie diet and a high-fat high-calorie diet.

No clinically significant pharmacokinetic interactions between voriconazole and indinavir in healthy volunteers.

Aims: Voriconazole is a new triazole antifungal agent, and is metabolized by the cytochrome P450 isoenzymes CYP2C9, CYP2C19 and to a lesser extent by CYP3A4. Protease inhibitors, such as indinavir, are also metabolized by cytochrome P450 (mainly CYP3A4). As these drugs are likely to be coadministered, these studies were performed to assess the pharmacokinetic interactions, safety and toleration of these drugs when taken together.
