Efficacy and safety of rademikibart (CBP-201), a next-generation mAb targeting IL-4Rα, in adults with moderate to severe atopic dermatitis: A phase 2 randomized trial (CBP-201-WW001).

Background: Rademikibart (CBP-201) is a next-generation IL-4 receptor alpha-targeting antibody.

Objective: We sought to evaluate rademikibart in adults with moderate to severe atopic dermatitis.

Methods: A total of 226 patients were randomized, double-blind, to subcutaneous rademikibart (300 mg every 2 weeks [Q2W], 150 mg Q2W, 300 mg every 4 weeks [Q4W]; plus 600-mg loading dose) or placebo.

A Mini Review of the Impact of Baseline Disease Severity on Clinical Outcomes: Should We Compare Atopic Dermatitis Clinical Trials?

Based on clinical trials of systemic treatments in adults with moderate-to-severe atopic dermatitis (AD) reported between 2014 and 2023, we used linear regression to investigate relationships between baseline Eczema Area and Severity Index (EASI) scores and (1) study start date, (2) EASI response, and (3) rescue medication rates. Analysis 1 was conducted with all patients from monotherapy and combination therapy trials; analyses 2 and 3 used monotherapy trial placebo arms. Across 32 trials with a baseline inclusion criterion of EASI ≥ 16, baseline mean EASI scores decreased with study start date.

Substrate Modification during Chemical Vapor Deposition of hBN on Sapphire.

A comparison of hexagonal boron nitride (hBN) layers grown by chemical vapor deposition on -plane (0001) versus -plane (112̅0) sapphire (α-AlO) substrate is reported. The high deposition temperature (>1200 °C) and hydrogen ambient used for hBN deposition on sapphire substantially alters the -plane sapphire surface chemistry and leaves the top layer(s) oxygen deficient. The resulting surface morphology due to H etching of -plane sapphire is inhomogeneous with increased surface roughness which causes non-uniform residual stress in the deposited hBN film.

Tuning Microbial Activity via Programmatic Alteration of Cell/Substrate Interfaces.

A wide portfolio of advanced programmable materials and structures has been developed for biological applications in the last two decades. Particularly, due to their unique properties, semiconducting materials have been utilized in areas of biocomputing, implantable electronics, and healthcare. As a new concept of such programmable material design, biointerfaces based on inorganic semiconducting materials as substrates introduce unconventional paths for bioinformatics and biosensing.

Oxidative Stress Transcriptional Responses of at GaN Interfaces.

Microorganisms regulate their interactions with surfaces by altering the transcription of specific target genes in response to physicochemical surface cues. To assess the influence of surface charge and surface chemistry on the transcriptional oxidative stress response, we evaluated the expression of three genes, , , and from the Gram-negative bacterium, after a short exposure to GaN interfaces. We observed that both surface charge and surface chemistry were the factors regulating the transcriptional response of the target genes, which indicates that reactive oxygen species (ROS) generation and the ROS response at the GaN interfaces were affected by changing surface properties.
