CD4-mediated regulatory T-cell activation inhibits the development of disease in a humanized mouse model of allergic airway disease

2012

Background Based on their potency to control allergic diseases, regulatory T (Treg) cells represent a promising target for novel strategies to interfere with allergic airway inflammation. We have previously demonstrated that stimulation of the CD4 molecule on human Treg cells activates their suppressive activity in vitro and in vivo . Objective We sought to determine the effect of CD4-mediated Treg-cell activation on pulmonary inflammation in a humanized mouse model of allergic airway inflammation. Methods PBMCs obtained from donors allergic to birch pollen or from healthy donors were injected into NOD-severe combined immunodeficiency γc −/− mice, followed by allergen airway challenges and …

Characterization of the interstitial lung and peripheral blood T cell receptor repertoire in cigarette smokers.

2005

T lymphocytes modulate the pulmonary inflammatory response. The aim of this study was to evaluate the clonality within the interstitial lung and peripheral blood T cell receptor (TCR) repertoire in smokers. Interstitial T lymphocytes were isolated from surplus tissue of 16 patients (63 +/- 9 [+/- SD] yr old, 11 male) undergoing surgery due to lung cancer (n = 15) or emphysema. TCR clonality was assessed by PCR amplification followed by spectratyping. Nearly all TCR of interstitial lung lymphocytes showed oligoclonal bands (CD4(+) subset 13/16 patients, 81%; CD8(+) 100%) indicating a specific differentiation. Peripheral blood T lymphocytes (PBL) TCR (especially CD4(+)) had less oligoclonal b…

Efficacy of a fixed combination of ciclesonide and formoterol: the EXCITED-study.

THE RECOVERY-ELISA—A NOVEL ASSAY TECHNIQUE TO MONITOR THERAPY WITH HUMANIZED ANTIBODIES: THE EXAMPLE OF OMALIZUMAB

2013

The therapeutic use of antibodies has grown exponentially, providing new treatment options for various diseases. Monitoring treatment with therapeutic antibodies is a particular challenge because often the target antigen is no longer measurable or the results are unreliable. To overcome this problem, a recovery-ELISA was developed to quantify therapeutic antibody and antigen by a modification of the traditional sandwich immunoassay using omalizumab as an example. Standard serum samples were spiked with IgE and omalizumab in a certain concentration range to create standard curves. After incubation and washout procedures, the reaction was stopped and the plate read with bichromatic absorbance…

An open-label, prospective phase I/II study evaluating the immunogenicity and safety of a ras peptide vaccine plus GM-CSF in patients with non-small …

2007

Mutations of the ras gene have been reported in 20-40% of NSCLC patients. If present, they are critical for the malignant phenotype of these tumors. Therefore, targeting them by specific vaccination is a promising therapeutic approach. In a clinical trial we screened for ras mutations in patients with NSCLC. Patients with ras-positive tumors were immunized six times intradermally with a mixture of seven peptides representing the most common ras mutations. Objectives of the study were the feasibility, efficacy and safety of the vaccination. In addition, the induction of a specific immune reaction was investigated by DTH tests, and the induction of peptide-specific T cells was tested in ex vi…

Summary Background Interleukin 13 is a central mediator of asthma. Tralokinumab is a human interleukin-13 neutralising monoclonal antibody. We aimed to assess the efficacy and safety of two dosing regimens of tralokinumab in patients with severe uncontrolled asthma. Methods We did a randomised, double-blind, placebo-controlled, parallel-group, multicentre, phase 2b study at 98 sites in North America, South America, Europe, and Asia. Patients aged 18–75 years with severe asthma and two to six exacerbations in the previous year were randomly assigned (1:1), via an interactive voice-response or web-response system, to one of two dosing regimen groups (every 2 weeks, or every 2 weeks for 12 wee…

Vitamin D Insufficiency In Adult Asthma Is Associated With Asthma Severity And Control

2012

Data in asthmatic children suggest that low vitamin D levels are associated with poor asthma control, reduced lung function, and increased medication intake. To investigate the role of vitamin D insufficiency in adult asthmatics 25-hydroxyvitamin D was measured in 280 adult patients with asthma (mean±SEM: 45.0±0.8 yrs., 40% male, FEV1 74.9±1.4%) and correlated with clinical parameters of asthma control. The majority of patients had severe asthma (n=155, 55%) and were uncontrolled (n=144, 51%). Serum levels of vitamin D were significantly related to asthma severity (mean±SEM: intermittent 31.1±3.2 ng/ml, mild 27.3±1.6 ng/ml, moderate 26.5±1.5, severe 24.0±0.9, p=0.046) and asthma control (co…

Against all odds: anti-IgE for intrinsic asthma?

2013

For many years, pathogenetic concepts and the results of clinical trials supported the view that anti-IgE treatment is specifically effective in allergic asthma. However, there is now growing clinical and mechanistic evidence suggesting that treatment with the anti-IgE antibody omalizumab can be effective in patients with intrinsic asthma. Therefore, large and well-controlled clinical trials with anti-IgE are urgently warranted in patients with intrinsic asthma. In addition, there is a need to find new biomarkers which can identify patients with asthma who respond to anti-IgE treatment.

&lt;p&gt;Switch from IL-5 to IL-5-Receptor α Antibody Treatment in Severe Eosinophilic Asthma&lt;/p&gt;

2020

Background Anti-IL-5 antibodies represent an established therapy for severe eosinophilic asthma (SEA), but some patients show inadequate response. The objective of this study was to assess the effects of a switch to anti-IL-5Rα therapy in patients with inadequate response to anti-IL-5 therapy. Methods In this retrospective multi-centre, real-life study, we analysed all SEA patients switched from anti-IL-5 to anti-IL-5Rα therapy due to inadequate response or intolerability. Pulmonary function tests, blood gas analyses, asthma control tests (ACT) and oral corticosteroid (OCS) usage were analysed and compared at three timepoints: baseline (BL, before anti-IL-5 therapy), timepoint 1 (T1, under …

P294 Benefits of tiotropium/olodaterol over tiotropium at delaying clinically significant events in patients with copd classified as gold B

2016

Rationale The once-daily combination of tiotropium (T), a long-acting muscarinic antagonist, and olodaterol (O), a long-acting β 2 -agonist, has demonstrated efficacy and safety in COPD. Two large clinical studies (TONADO ® 1 + 2) have also demonstrated the benefits of T/O compared to the monocomponents in patients with moderate to very severe COPD. This post hoc analysis investigated whether T/O is more effective than T at delaying clinically significant events in patients with GOLD stage B COPD. Methods A total of 5162 patients were randomised to O 5 µg, T 2.5 µg, T 5 µg, T/O 2.5/5 µg or T/O 5/5 µg (delivered via Respimat ® inhaler) in two 52-week, parallel-group, double-blind studies (NC…
