30 UniTinA-asthma™ Phase III trial programme ongoing The PrimoTinA-asthma studies are part of Boehringer Ingelheim's comprehensive ongoing Phase III trial programme named UniTinA-asthma, which was designed to establish the efficacy and safety of tiotropium, delivered by the Respimat Soft Mist Inhaler (SMI) in patients with asthma. UniTinA-asthma includes trials in adults, adolescents and children and involves over 4,000 patients in more than 150 sites globally. Included in the UniTinA-asthma umbrella programme are the following studies: PrimoTinA-asthma™ Adult study /.417 [4;5] (Kersjten atak) NCT , NCT NCT NCT MezzoTinA-asthma™ Adult study /.419 [6;7] NCT , NCT NCT NCT GraziaTinA-asthma™ Adult study [8] NCT NCT VivaTinA-asthma™ Paediatric study /.446 [9;10] NCT , NCT NCT NCT RubaTinA-asthma™ Adolescent study [11] NCT NCT PensieTinA-asthma™ Adolescent study [12] NCT NCT TALC NCT Bateman NCT Kersjten Tio improves lung function NCT

31 A) PrimoTinA-asthma™ Adult study /.417 [4;5] Kersjten atak NCT NCT , NCT NCT B) MezzoTinA-asthma™ Adult study /.419 [6;7] These studies have been completed. 1- Evaluation of Tiotropium 2.5 and 5 Mcg Once Daily Delivered Via the Respimat® Inhaler Compared to Placebo and Salmeterol HydroFluoroAlkane (HFA) Metered Dose Inhaler (MDI) (50 Mcg Twice Daily) in Patient With Moderate Persistent Asthma I NCT NCT Evaluation of Tiotropium 2.5 and 5 Mcg Once Daily Delivered Via the Respimat® Inhaler Compared to Placebo and Salmeterol HydroFluoroAlkane (HFA) Metered Dose Inhaler (MDI) (50 Mcg Twice Daily) in Patient With Moderate Persistent Asthma II NCT The aim of these trials is to evaluate the efficacy and safety of 2.5 and 5 mcg tiotropium over a 24-week treatment period as compared to placebo and salmeterol (50 mcg twice daily). Tiotropium inhalation solution delivered by the Respimat® inhaler will be examined on top of maintenance treatment with inhaled corticosteroid controller medication in patients with moderate persistent asthma. Efficacy and safety will be assessed by measuring effects on lung function, effects on asthma exacerbations, effects on quality of life, effects on asthma control, effects on health care resource utilisation, and number of adverse events.NCT

32 C) GraziaTinA-asthma™ Adult study [8] This study has been completed. 1- Efficacy and Safety of 2 Doses of Tiotropium Via Respimat in Adult Patients With Mild Persistent Asthma NCT NCT The aim of this trial is to evaluate the efficacy and safety of 2.5 and 5 mcg tiotropium compared to placebo over 12 week treatment period. Tiotropium inhalation solution will be delivered via Respimat inhaler and will be examined on top of maintenance inhaled corticosteroid treatment in patients with mild persistent asthma. Efficacy and safety will be assessed by measuring the effects on lung functions, effects on lung exacerbations, effects on asthma control and numbers of adverse events. D) VivaTinA-asthma™ Paediatric study /.446 [9;10] This study is currently recruiting participants. 1- Efficacy and Safety of 2 Doses of Tiotropium Respimat® Compared to Placebo in Children With Moderate Persistent Asthma NCT NCT The overall purpose of the trial is to evaluate efficacy and safety of tiotropium inhalation solution delivered via Respimat® inhaler (2.5 mcg and 5 mcg once daily in the evening) over 48 weeks, compared to placebo, in children (6 to 11 years old) with moderate persistent asthma. 2- Efficacy and Safety of 2 Doses of Tiotropium Respimat® Compared to Placebo in Children With Severe Persistent Asthma NCT This study is currently recruitingNCT The overall purpose of the trial is to evaluate efficacy and safety of tiotropium inhalation solution (2.5 mcg and 5 mcg) delivered via Respimat® inhaler once daily in the evening over 12 weeks, compared to placebo, as add-on controller therapy on top of usual care in children (6 to 11 years old) with severe persistent asthma.

33 E) RubaTinA-asthma™ Adolescent study [11] This study has been completed. Efficacy and Safety of 2 Doses of Tiotropium Via Respimat Compared to Placebo in Adolescents With Moderate Persistent Asthma NCT NCT The aim of the study is to evaluate efficacy and safety of a 48-week treatment with two doses of tiotropium bromide compared to placebo in adolescent patients with moderate persistent asthma. Efficacy and safety will be assessed by measuring lung function parameters and evaluating the effects on asthma exacerbations, on Quality of life, on health care resource utilisation an on the number of adverse events. F) PensieTinA-asthma™ Adolescent study [12] This study has been completed. Efficacy and Safety of 2 Doses of Tiotropium Respimat Compared to Placebo in Adolescents With Severe Persistent Asthma NCT NCT The overall purpose of the trial is to evaluate efficacy and safety of tiotropium inhalation solution delivered via Respimat® inhaler (2.5 mcg and 5 mcg once daily) over 12 weeks, compared to placebo, as add-on controller therapy on top of usual care in adolescents (12 to 17 years old) with severe persistent asthma. The primary objective of the trial is to demonstrate superiority of tiotropium (5 mcg and possibly 2.5 mcg once daily in the evening) over placebo with regard to the primary pulmonary function endpoint after 12 weeks of treatment. Secondary objectives are to evaluate efficacy of tiotropium with regard to other endpoints, and to evaluate the safety of tiotropium, compared to placebo, as add-on controller therapy on top of usual care in this patient population.
