(3) No evidence that dyspepsia is exclusively relieved by defecation or associated with the onset of a change in stool frequency or stool form (not IBS). -All patients enrolled must have a negative upper GI endoscopies to exclude organic disease, such as esophagitis, gastric or duodenal ulcer, esophageal or gastric neoplasia, within 1 month prior to enrolment. At the time of the endoscopy, patients must have been off Proton Pump Inhibitors (PPIs) and H2-receptor antagonists for at least 14 days. -Patients in whom heartburn is infrequent, not exceeding a frequency of one episode per week, and is subordinate to their abdominal pain or discomfort. -Evidence of H. pylori negative status, as confirmed by either C-13 within 7 days prior to enrolment. -Baseline severity of at least moderate on the LDQ (total score of 9 and above). Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) no F.1.3.1 Number of subjects for this age range
Exclusion criteria
Exclusion criteria: -Patients suffering mainly or exclusively from symptoms corresponding to reflux disease. -Patients suffering from regurgitation and/or vomiting. -Abnormal upper GI endoscopy findings -Clinical evidence or diagnosis of gallbladder or biliary tract disease, pancreatic disease confirmed by upper abdominal ultrasound or diagnosis of chronic inflammatory bowel disease. -Patients with clinically relevant ECG abnormalities such as a QRS duration > 110 msec, heart rate 470 msec on the screening ECG. -Patients with known arrhythmias, such as: chronic/paroxysmal atrial fibrillation, supraventricular tachycardia, ventricular tachycardia or “torsades de pointe”. -Active psychiatric disorder. -Health conditions that would interfere with the study objectives or might impair the compliance of the patient. -Severe hepatic, renal, cardiac, metabolic, hematological or malignant diseases or clinically relevant deviations in laboratory values (AST/ALT) greater than twice the upper limit of normal, serum creatinine > 2 mg/dl, hyperthyroid or hypothyroid patient according to the medical judgement of the investigator. -Patients with hypokalemia (serum potassium less than or equal to 4 mmol/l) and hypomagnesemia (serum magnesium < 1.7 mg/dl). -Any known hypersensitivity to the ingredients of the investigational drug. -Patients with a genetic disease called trimethylaminuria (fish odor syndrome). -Patients with laxative abuse, as judged by the investigator. -Patients with any known specific food intolerance (whose symptoms disappear completely and persistently if he/she does not eat the particular food, e.g., lactose intolerance). -Smoker who has significantly changed his/her smoking habits within 14 days prior to administration of study medication, or non-smoker who has become a smoker within 14 days prior to administration of study medication. -Pregnancy or lactation. -Women with childbearing potential who do not apply a medically accepted method of contraception. -Known alcoholism or drug abuse.

| Main Objective: To establish the efficacy of itopride HCl 100 mg t.i.d compared with placebo in improving the symptoms of functional dyspepsia after 8 weeks of treatment. Efficacy will be measured using an adapted version of the LDQ (Leeds Dyspepsia Questionnaire), which will monitor the change in the overall severity of functional dyspepesia during the treatment phase. The LDQ questions assessing the symptoms of upper abdominal pain and fullness will be used as the primary outcome measure, along with the Global Patient Assessment of Efficacy, utilizing the response to a single question: “Please rate the strength of your upper abdominal complaints in the past 14 days. Compared to the condition at the outset of treatment, how much have they changed? Please mark the statement that best applies to you: symptom-free, markedly improved, slightly improved, unchanged, worse”. ; Secondary Objective: To compare itopride HCl and placebo for the following secondary efficacy variables: -Change from baseline in the overall severity of FD as measured at week 4 and 8, using the LDQ severity score. -Change from baseline in the patient's quality of life as measured by the Nepean Dyspepsia Index (NDI) at week 0, 2, 4 and 8. -Change from baseline in the overall severity of FD as measured by the NDI symptom score at week 0, 2, 4, and 8. -Change in the Global Patient Assessment of the efficacy of study medication versus placebo measured at week 2 and 4. Safety Endpoints:· -To establish the safety profile of itopride HCl as measured by adverse events reporting, vital parameters and performance of safety lab tests. -To establish cardiac safety measured by repeated 12 lead ECGs, at screening, baseline, 2- and 8-week visits. ; Primary end point(s): The two co-primary efficacy endpoints will be: -Questions 1 and 8 | — |
