简要总结
Heartburn is the main symptom of Gastroesophageal Reflux Disease (GERD), which, accompanied by acid regurgitation and other symptoms, has a substantial negative impact on a patients' quality of life. Although a number of treatment options are available, a more effective therapy is still required. The failure of proton pump inhibitors (PPIs) to completely resolve symptoms is an accepted problem, with approximately 25% of patients with GERD continuing to experience the symptoms of heartburn in spite of treatment. This study aims to demonstrate an earlier onset to relief of symptoms in patients suffering from heartburn associated with GERD using an immediate-release omeprazole/sodium bicarbonate formulation when compared with delayed-release omeprazole (Losec®).

入选标准
- •Study patients will be included in the study if they satisfy the following criteria:
- •Male or female, between 18 and 75 years old.
- •History of frequent episodes of heartburn associated with GERD for at least 2 3 days per week during 2-4 weeks before screening and have responded to standard PPI therapy in the past 12 months.
- •Have not taken on-demand PPI therapy for > 3 consecutive days within 4 weeks before the screening period.
- •The patient's written informed consent must be obtained prior to inclusion.
- •Willing and able to complete the entire procedure and to comply with study instructions.
- •Females of childbearing potential must employ an adequate method of birth control.
- •Inclusion criteria applicable to Screening period:
- •Recorded at least 1 evaluable episode of heartburn on 2 separate days at level 4 or higher on the 9-point Likert severity scale (point 3 on a 0-8 point scale) prior to randomisation.
- •Competent in the use and completion of the e-diary.
排除标准
- •Study patients will be excluded if they meet any of the following criteria:
- •Age < 18 or > 75 years old.
- •Intake of any medication for the purpose of the eradication of Helicobacter pylori (H. pylori) during the last 28 days before the start of the study.
- •Intake of systemic glucocorticoids or non-steroidal anti-inflammatory drugs (NSAIDs) including COX-2-inhibitors (≥ 3 consecutive days per week) during the last 28 days before the start of the study; except regular intake of enteric coated aspirin dosages up to 150 mg/d.
- •Previously underwent acid-lowering surgery or other surgery of the oesophagus and/or upper gastrointestinal tract (excluding: appendectomy, cholecystectomy and polypectomy).
- •History of co-existing disease that affects the oesophagus (e.g. Barrett's oesophagus, Zollinger-Ellison syndrome, oesophageal stricture), and have undergone an endoscopy with results of incomplete healing of erosions following standard PPI therapy within the last 3 months.
- •History of active gastric or duodenal ulcers within 3 months of the first dose of the study drug or had acute upper gastrointestinal (GI) bleeding within last 6 months.
- •Documented presence of severe renal or hepatic insufficiency.
- •Known hypersensitivity to omeprazole.
- •Concurrent participation in a study with an investigational drug or participation within 30 days of study entry.
- •Females who are pregnant, or planning a pregnancy. Females of child bearing potential not using reliable methods of birth control.
- •Clinically significant laboratory abnormality or disease which, in the opinion of the Investigator, will create a risk for the patient, obscure the effects of study treatment or interfere with study results.
- •Received or require any of the following drugs within 2 weeks before the first dose of study or continue to need these drugs for concurrent therapy: theophylline, bismuth salts, warfarin, phenytoin, tacrolimus, diazepam, cyclosporine, disulfiram, benzodiazepines, barbiturates, antineoplastic agents, erythromycin, clarithromycin, sucralfate, clopidogrel or protease inhibitors.
- •Taking concomitant medications that rely on the presence of gastric acid for optimal bioavailability (e.g. ketoconazole, ampicillin esters or iron salts).
- •Onset of psychoactive medication (e.g. depressants, stimulants or hallucinogens) in the previous 6 months and during the entire course of the study.
- •Exclusion criteria applicable to Screening period:
- •Recorded < 1 episode of heartburn on 2 separate days at level 4 on the 9 point Likert severity scale (point 3 on a 0-8 point scale) during the 7 day screening period prior to randomisation
- •Completing < 90% (< 9 out of 10) of the time points with evaluable data on the e diary.
