E.3 | Principal inclusion criteria |
Inclusion criteria for run-in period:
Subjects will be eligible to enter the run-in period if all of the following criteria are met:
1. Subjects to provide written informed consent prior to any study procedures being performed.
2. Male or female subjects aged 18 years or over, inclusive, on the day the informed consent is signed.
3. Subjects with a diagnosis of FD (postprandial distress syndrome) as defined by the Rome III Criteria* (see Appendix A). Criteria must be fulfilled for the 3 months prior to informed consent with symptom onset at least 6 months prior to informed consent.
Symptoms must include one or both of the following:
i. Bothersome postprandial fullness (PPF), occurring after ordinary-sized meals, more than 1 day per week
ii. Early satiation (ES) that prevents finishing a regular meal, more than 1 day per week
There must be no evidence of structural disease (including at upper endoscopy) that is likely to explain the symptoms.
4. Subjects must have consulted for dyspeptic symptoms at least once during the 6 months prior to informed consent. If there are no medical records, the subject should be asked when the symptoms started.
5. Subjects must present PPF or ES as the most bothersome symptom during the 6 months prior to informed consent.
6. Subjects must have a normal endoscopy result within the 6 months (3 months in case of subjects who are H. pylori positive) prior to informed consent or during the screening period.
• If no normal endoscopy results are available from the 6 months (3 months for H. pylori positive subjects) prior to informed consent, an endoscopy must be conducted during the screening period and must be normal for the subject to be eligible. If H. pylori status is unknown, then a H. pylori test must be conducted during the screening period although H. pylori status (i.e., positive or negative) is not an eligibility criterion.
7. Subjects must be able to understand the study, comply with the study requirements, and return to the investigational site for assessments at specified times.
8. Subjects must be able to understand the symptom definitions and how to record their severity using the LPDS incorporated in an electronic Patient Reported Outcome (ePRO) device.
9. Female subjects of childbearing potential must provide a negative pregnancy test (urine dipstick) at screening (Visit 1 or 2). Female subjects of childbearing potential must agree to use acceptable contraceptive methods (i.e., contraceptive implant, injectable or patch hormone therapy, oral contraceptives in combination with barrier methods [e.g., condoms] supplemented with spermicidal foam/gel/film/cream/suppository, intrauterine device, sexual abstinence, or surgical sterilisation of the subject or the subject’s sexual partner) during the screening, run-in, treatment, and follow-up periods. Non-childbearing potential includes being surgically sterilized at least 6 months prior to informed consent, post-menopausal, or defined as amenorrhoea for at least 12 months prior to informed consent.
Male subjects with partners of childbearing potential must agree to use acceptable contraceptive methods (i.e., barrier method [e.g., condoms] supplemented with spermicidal foam/gel/film/cream/suppository in combination with another contraceptive measure as described above) during the screening, run-in, treatment, and follow-up periods.
Inclusion criteria for open-label treatment period
Subjects will be eligible to enter the open-label treatment period if all of the following criteria are met:
1. Subjects must present ES (Question 1 of LPDS) or PPF (Question 2 of LPDS) with a severity of at least moderate and a frequency of at least 2 days a week during the run-in period.
2. Female subjects of childbearing potential must provide a negative pregnancy test (urine dipstick) at Visit 3. |

E.4 | Principal exclusion criteria |
1.Subjects on PPI(s) who are unable to discontinue PPI medication by the end of the screening period (Visit 2).
•Subjects taking PPIs at the time of informed consent will be asked to discontinue the medication and return after a 14- to 21-day washout period to complete screening assessments at Visit 2.
2. Subjects taking drugs that affect gut motility, gut sensitivity and/or acid secretion (see list of prohibited medications, Appendix B) who are unable to discontinue these drugs by the end of the screening period(Visit 2).
•Subjects taking drugs that affect gut motility, gut sensitivity and/or acid secretion* at the time of informed consent will be asked to discontinue the medication and return after a 14- to 21-day washout period to complete screening assessments at Visit 2.*Note: no washout is required for medications listed in the “antacids and cytoprotectors” category in Appendix B.
