E.1.1 | Medical condition(s) being investigated |
Patients with non-cystic fibrosis bronchiectasis |
Patienten met non-cystic fibrose bronchiectasieen |
|
E.1.1.1 | Medical condition in easily understood language |
Non-cystic fibrosis (non-CF) bronchiectasis is a chronic disorder of the airways characterized by dilation and destruction. The presence of infection and a inflammatory response are characteristic. |
Bij non-CF bronchiectasieen ontstaat verwijding en destructie van de luchtwegen, waarbij recidiverende infecties en een continue onstekingsreactie. |

E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to determine whether TIS once daily as compared to placebo may reduce the number of exacerbations in non-CF bronchiectasis and is equally effective as TIS BID open label 4 weeks on-off. |
primaire uitkomstmaat is een 50% reductie in exacerbatie rate bij het gebruik van tobramycin inhalation solution |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of this study are to assess the effect of TIS treatment on time to next exacerbation, FVC% predicted, FEV1% predicted, LTRI-VAS, Quality of Life-Bronchiectasis (QOL-B), Leicester cough score, bacterial load in sputum and tobramycin resistance for the initial pathogens. |
secundaire uitkomstmaten zijn longfunctie, kwaliteit van leven, bacterien in sputum en tobramycine resistentie |
|

E.5 End points |
E.5.1 | Primary end point(s) |
50% reduction in exacerbation rate in patients using TIS (OD or BID) |
zie boven |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
After informed consent patients have 3 monthly visits. During the visits patients have to deliver a sputum sample, fill in the QoL questionnaires and spirometry will be performed according the study schedule. Also a blood sample will be taken during a number of visits. |

|
E.5.2 | Secondary end point(s) |
Secondary outcome parameters are lung function (FEV1, FVC), QoL (QOL-B), LTRI-VAS, Leicester cough score), bacterial load in sputum and tobramycin resistant pathogens. |
