Tiotropium Respimat add-on therapy is an effective bronchodilator,
producing clinically meaningful improvements versus placebo in lung
function in patients aged 6–17 years with severe symptomatic asthma,
mirroring findings in adult patients with symptomatic asthma.

Introduction
Tiotropium Respimat (tioR) add-on therapy to inhaled corticosteroids
(ICS) with or without additional controllers has been shown to improve
lung function in Phase II and III studies of adults, adolescents and children

studies was change from baseline (response) in peak forced expiratory
volume in 1 second within 3 hours post-dose (FEV1[0–3h]); the key
secondary end point was trough FEV1 response (measured 10 minutes
before the next dose of study medication); a further end point was
forced expiratory flow between 25% and 75% of the forced vital
capacity (FVC; FEF[25–75%]) response; the post hoc end point was
trough FEV1/FVC ratio. All end points were measured at Week 12.
Results
793 participants (VivaTinA n = 401; PensieTinA n = 392) were
randomized across both trials; 792 were included in this pooled full
analysis set. Baseline demographics and disease characteristics were
balanced between treatment groups. TioR add-on therapy improved
lung function in the pooled population at Week 12, with tioR 5 μg

Sputum HMGB1 Levels were significantly higher in all patients with
asthma (p < 0.0001). An inverse correlation between sputum HMGB1
Levels and pulmonary function parameters was observed only in
moderate (T0: FEV1% r:-0.9891, p < 0.001; T3: FEV1% r:-0.6763,
p < 0.001; T6: FEV1% r:-0.5419, p < 0.05) and in severe asthmatic
children (T0: FEV1% r:-0.8696, p < 0.001; T3: FEV1% r:-0.6477,
p < 0.05; T6: FEV1% r:-0.8627, p < 0.001) (Fig. 1). After ICS treatment,
a significant decrease of sputum HMGB1 Levels was noted in
moderate (T0: 93.44 ± 20.65 ng/ml vs. T3: 77.96 ± 1.81 ng/ml vs.
T6: 67.75 ± 3.01 ng/ml; p < 0.0001) and in severe asthmatic children
