Participant Flow

Four randomized patients were excluded from the ITT analysis due to missing efficacy data (2 patients), no investigational product given (1 patient), and being unblinded by the investigator (1 patient). The patient who received no investigational product was excluded from the safety analysis and is not included in the Baseline Characteristics.

SECONDARY outcome

Timeframe: Baseline to 6 months

Participants must have both baseline and flow up measure to be included in analysis. Each morning and evening, the patient will be asked to record his/her asthma symptoms (sx) in the diary. The asthma sx scores during night- and daytime will be assessed by the patient according to the following scoring system: 0 = no asthma sx; 1 = you are aware of your asthma sx but can easily tolerate the sx; 2 = your asthma sx are causing you enough discomfort to cause problems with normal activities (or with sleep); 3 = you are unable to do your normal activities (or sleep) because of your asthma. The total symptom score is the sum of the night- and daytime scores.

The Asthma Quality of Life Questionnaire, Standardized Version (AQLQ(S))has been developed by and includes 32 questions in 4 domains: activity limitation, symptoms, emotional function, and exposure to environmental stimuli. It is used to measure the physical and emotional impact of the disease in the selected areas of life. Participants must have both baseline and follow up measure to be included in analysis.AQLQ(S) score based on a 7-point scale that ranged from 1 (worst quality of life) to 7 (best quality of life).

The RDQ questionnaire is used to assess six GI symptoms during the previous week (a burning feeling behind the breastbone, pain behind the breastbone, a burning feeling in the centre of the stomach, pain in the centre of the stomach, an acid taste in the mouth, unpleasant movement of material upwards from the stomach). Each symptom is given a frequency score on a six-point scale (from 0=did not have to 5=daily) and an intensity score on a six-point scale (from 0=did not have to 5=severe). Three domain scores are calculated by forming averages of the frequency and intensity scores of selected symptoms (heartburn: the first two symptoms; dyspepsia: the next two symptoms; regurgitation: the last two symptoms). The overall GERD score is calculated as the average of the hearburn and dyspepsia domain scores. The GERD score can thus range from 0 to 5.
