E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the efficacy of clebopride 0.5 mg t.i.d. on the perceived overall treatment evaluation (by means of a Likert scoring system) |
|
E.2.2 | Secondary objectives of the trial |
To assess the effect of clebopride on the number of symptom events, indicated by the patient, during high-resolution impedance manometry, the number of flow event identified on High Resolution impedance Manometry (HRiM), lower esophageal sphincter (LES) pressure, the number of transient LES relaxations (TLESRs) and on intra-gastric pressure |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Minimum 18 years old. 2. History assessed by a gastroenterologist consistent with probable rumination syndrome. 3. Have completed a gastro-duodenoscopy, within 12 months, showing no anatomical abnormality of the stomach or esophagus, which can explain the patients’ symptoms. 4. Patients will have to have tried the equivalent of 20mg of daily omeprazole for 2 weeks prior to consideration of inclusion in the study. 5. Sexually active women of child bearing potential participating in the study must use a medically acceptable form of contraception. Medically acceptable forms of contraception include oral contraceptives, injectable or implantable methods, intrauterine devices, or properly used barrier contraception. 6. Subjects must be capable of understanding and be willing to provide signed and dated written voluntary informed consent before any protocol-specific screening procedures are performed.

E.4 | Principal exclusion criteria |
1. Endoscopic signs of severe erosive esophagitis (≥ grade B, Los Angeles classification) on endoscopy performed during PPI treatment in the 12 months prior to screening. 2. Systemic diseases, known to affect esophageal motility. 3. Surgery in the thorax or in the upper part of the abdomen (appendectomy and cholecystectomy are allowed). 4. QT c>450 ms. 5. Parkinson’s syndrome or related syndromes. 6. History of adverse drug reactions (pseudo-Parkinsonism, tardive dyskinesia, restless legs) upon exposure to dopaminergic drugs. 7. Concomitant use of medications such as anticholinergics, tricycle antidepressants, baclofen, dopamine antagonists or dopaminergic drugs and prokinetics. 8. Significant neurological, respiratory, hepatic, renal, hematological, cardiovascular, metabolic or gastrointestinal cerebrovascular disease as judged by the investigator. 9. Major psychiatric disorder – as determined by the clinicians. 10. Pregnancy or breast-feeding. 11. History of poor compliance. 12. History of/or current psychiatric illness that would interfere with ability to comply with protocol requirements or give informed consent. 13. History of alcohol or drug abuse that would interfere with ability to comply with protocol requirements.
