Population pharmacokinetics and pharmacodynamics of inhaled ciclesonide and
fluticasone propionate in patients with persistent asthma. 
Inhaled corticosteroids, such as fluticasone propionate (FP) and ciclesonide
(CIC), are commonly used for the treatment of asthma. The objectives of this
study were to characterize pharmacokinetics (PK) and pharmacodynamics (PD) of FP
and a pharmacologically active metabolite of CIC (desisobutyryl-ciclesonide
[Des-CIC]) using a nonlinear mixed-effects modeling approach, to investigate
selected covariate effects on PK and PD parameters of FP and Des-CIC, and to
assess the systemic effects of FP and CIC on serum cortisol suppression in
patients with persistent asthma...
Comparable spirometric efficacy of tiotropium compared with salmeterol plus fluticasone in patients with COPD: a pilot study. 
BACKGROUND: International guidelines recommend the long-acting anticholinergic, tiotropium, or long-acting beta 2-agonists as maintenance therapy in patients with moderate-to-very severe chronic obstructive pulmonary disease (COPD). The efficacy of long-acting beta(2)-agonists combined with inhaled corticosteroids (ICS) in the treatment of COPD has also been confirmed for severe and very severe COPD, but data comparing tiotropium with the combination of a long-acting beta 2-agonist and an ICS are lacking... CONCLUSIONS: Six weeks of treatment with tiotropium resulted in comparable bronchodilation compared with salmeterol plus fluticasone in patients with moderate-to-very severe COPD, despite tiotropium patients having lower lung function and fewer patients considered reversible at baseline. The results of this pilot study will aid planning for further large-scale comparative studies.
Effect of ciclesonide treatment on allergen-induced changes in T cell regulation in asthma. 
BACKGROUND: The allergen-induced release of CCL17/thymus and activation-regulated chemokine (TARC) may be crucial in asthmatic airway inflammation by recruitment of Th2 cells. In addition, it might lead to aberrant Th2 cell activity through impairment of beta2-adrenergic receptor (beta2-AR) control. We questioned how chemokine patterns change upon allergen challenge and whether treatment with the inhaled steroid ciclesonide can reduce chemokine release and subsequently prevent allergen-induced changes in Th2 cell regulation and migration... CONCLUSION: Our data support the hypothesis that CCL17 is involved in allergen-induced dysregulation of Th2 cell migration and cytokine production. Ciclesonide treatment inhibits T cell migration and cytokine production upon allergen inhalation, which is regulated independently from reducing CCL17 release, but may contribute to beneficial effects of ciclesonide on Th2-mediated airway inflammation. 2007 S.

Clinical Trials Related to Zetonna (Ciclesonide)
A Study Evaluating the Effect of Inhaled and Nasal Corticosteroids on Short Term Growth in Pediatric Subjects With Mild Asthma & Allergic Rhinitis [Not yet recruiting]
This study will provide the clinicians guidance on the safest combination of inhaled and
nasal corticosteroids for children with mild asthma and allergic rhinitis respectively;
however, one safety concern is that these products are independently known to have
dose-related effects on short term and intermediate term growth. Knemometry is a non
invasive technique for measuring short-term lower leg growth in children and is currently
the method of choice in growth studies of short duration. Subjects will be seen on a weekly
basis for 18 weeks and at each visit, lower leg length will be measured using knemometry.
A Safety and Efficacy Study of Ciclesonide Nasal Aerosol in Subjects 6-11 Years With Seasonal Allergic Rhinitis (SAR) [Recruiting]
This is a 2-week, multicenter, randomized, double-blind, placebo-controlled, parallel group,
efficacy and safety study of ciclesonide nasal aerosol administered once daily to male and
premenarchal female subjects 6 to 11 years-old diagnosed with SAR.
Small Particle Steroids in Refractory Asthma [Recruiting]
The purpose of this study is to determine whether an inhaled steroid with a small particle
size can be an additional treatment option in patients with refractory eosinophilic asthma.
Study of the Effect of Vitamin D as an Add-on Therapy to Corticosteroids in Asthma [Recruiting]
The purpose of the study is to find out if taking vitamin D in addition to an asthma
controller medication helps to prevent worsening of asthma symptoms and asthma attacks.
