E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary study objective is to assess the effect of AZD2516, measured as reduction in the total number of reflux episodes during a 3-hour post meal period compared to placebo. |
|
E.2.2 | Secondary objectives of the trial |
• To assess the effect of AZD2516, measured as reduction in the number of transient lower esophageal sphincter relaxations (TLESRs) during a 3-hour post meal period compared to placebo. • To assess the number of acid-, weakly acidic- and weakly alkaline reflux episodes during a 3-hour post meal period • To assess the height (mean proximal extent) and content (liquid, gas or a mixture) of the refluxate • To assess the time with esophageal pH between 4 and 6.5 during a 3-hour post meal period • To assess the time with esophageal pH<4 during a 3-hour post meal period • To assess the lower esophageal sphincter (LES) pressure during a 3-hour post meal period • To assess the number of concurrent TLESRs and acid- and weakly-or non acid reflux episodes during a 3-hour post meal period • To assess the effect of AZD2516 on the number of swallows during a 3-hour post meal period • To assess the pharmacokinetic profile of AZD2516 • To assess the safety and tolerability of AZD2516.

E.4 | Principal exclusion criteria |
1. Clinically significant illness within the 2 weeks prior to the first dose of the investigational product which may interfere with the objectives of the study, as judged by the investigator 2. Basal LES pressure of < 5 mmHg 3. History of previous or ongoing psychiatric disease/condition including psychosis, affective disorder, anxiety disorder, borderline state and personality disorder according to the criteria in the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV, APA 1994), as assessed by using the MINI interview (Sheehan et al 1997, Lecrubier et al 1997, Sheehan et al 1998, Amorim et al 1998) 4. Suicidal ideation of type 4 or 5 on the Columbia-Suicide Severity Rating Scale (C-SSRS) (Posner et al 2007) 5. History of psychotic disorder among first-degree relatives 6. History of use of antipsychotic, antidepressant or anxiolytic drugs, prescribed as well as non-prescribed use. History of antidepressants or anxiolytics for non-psychiatric conditions such as pain or postoperative insomnia is allowed 7. History of clinically significant cardiovascular, respiratory, renal, hepatic, neurological, mental or gastrointestinal disease, as judged by the investigator 8. Use of prescribed medication and over-the-counter (OTC) drugs (including herbal remedies minerals and vitamins) during 2 weeks before administration of investigational product. However, paracetamol may be taken occasionally for pain relief as well as OTC adrenergic nasal spray for relief of nasal congestion 9. Administration of any investigational product within 8 weeks prior to the first dose of AZD2516 12. Any clinically important abnormalities in rhythm, conduction or morphology of resting ECG obtained at the pre-entry visit, which may interfere with the interpretation of QTc interval changes. This includes subjects with any of the following: - Clinically significant PR (PQ) interval prolongation - Intermittent second or third degree AV block - Incomplete, full or intermittent bundle branch block (QRS<120 msec with normal QRS and T wave morphology is acceptable if there is no evidence of left ventricular hypertrophy) - Abnormal T wave morphology, particularly in the protocol defined primary lead (lead V2) - Prolonged QTcF >450 msec or shortened QTcF <350 msec or family history of long QT syndrome
