Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • Primary objective is to compare the anti-asthmatic effect of esomeprazole with that of placebo in adult asthmatics with gastroesophageal reflux by evaluating change in morning Peak Expiratory Flow from baseline (run-in) to treatment period.

Secondary Outcome Measures:
  • Secondary objectives are to investigate the effect on symptoms of GERD as measured by Reflux Disease Questionnaire from randomization to end of study and to assess safety and tolerability by AEs, laboratory tests, physical examination, and vital signs.
