Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • Daily diary cards and investigator symptom assessment to evaluate the efficacy of acid suppression therapy on symptoms associated with chronic posterior laryngitis (CPL) in patients without documented pharyngeal acid [ Time Frame: Dialy diary cards, investigator assessments, laryngoscopy at week 16 ]

Secondary Outcome Measures:
  • Daily diary cards and investigator symptom assessment throughout to evaluate the efficacy of acid suppression therapy on resolution of signs of CPL at weeks 8 and 16 in patients without documented pharyngeal acid reflux. [ Time Frame: Dialy diary cards, investigator assessments, laryngoscopy at weeks 8 and 16 ]
  • Quality of life Questionnaire [ Time Frame: Quality of life questionnaire completed at screening and week 16 ]
  • To evaluate the safety and tolerability by collecting an ongoing record of adverse events. [ Time Frame: Ongoing to week 16. ]
