A Long Term Prospective Follow Up Study For The CATO Study (SAS30018/SER9702) - Full Text View

Purpose

The CATO population is a very well documented population during two years. During this study patients were treated according to the CATO algorithm, after that patient were treated according to the Dutch national (GINA derived) guidelines up to 6 years of follow-up. The purpose of this prospective follow-up study is to understand the long-term effects of treatment. Therefore the measurements done at baseline (CATO part 1) are repeated after 6 years in this CATO-population (CATO follow-up).

Primary Outcome Measures:

Comparison of the mean annual in FEV1 (% predicted) between randomisation (CATO visit 2) and the current visit 2 between both treatment arms. [ Time Frame: 6 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Comparison of both treatment arms (BHR strategy versus reference strategy):• Lung function FVC and PEFR measured in the clinic between randomisation ( and current visit 2 expressed as the mean annual change of % predicted [ Time Frame: 6 years ] [ Designated as safety issue: No ]
• Percentage asthma symptom free days during 6 weeks of this extension study • Bronchial hyperresponsiveness, determined with PD20 methacholine between randomisation and current visit 2 [ Time Frame: 6 years ] [ Designated as safety issue: No ]
Growth rate between randomisation and current visit 2 (expressed as SD-scores)•frequency of asthma exacerbations between randomisation and current visit 2 [ Time Frame: 6 years ] [ Designated as safety issue: No ]
• Height at current visit 1 or at last measurement at which subject has reached their final height.• Cumulative ICS doses between randomisation and current visit 2 (if this can be achieved with sufficient reliability) [ Time Frame: 6 years ] [ Designated as safety issue: No ]
Quality of Life (Juniper questionnaire) [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
