Study summary

Patients with atypical gastro-esophageal reflux disease (GERD), include cough, globus, and non-cardiac chest pain (NCCP) usually require more aggressive or double dose proton pump inhibitor (PPI) therapy than patients with typical GERD. Dexlansoprazole is a new, dual delayed release formulation of PPI that increases the mean intragastric pH during a 24-hour period. The prospective, open-label, randomized study aims to compare the efficacy of two different PPI formula in treating patients with atypical GERD symptoms.

Patients with atypical GERD symptoms and a total Reflux Symptom Index (RSI) score ≥13 (cough, globus, and NCCP) will be invited to participate. Personal characteristics including age, sex, body mass index, and the severity of erosive esophagitis will be recorded. After enrollment, 120 subjects will randomly assign (at a 1:1 ratio) to receive either oral lansoprazole, Takepron OD 30 mg, once daily before breakfast or oral dexilansoprazole, Dexilant 60 mg, once daily before breakfast for 8 weeks. Subjects will record their symptoms (cough, globus, NCCP, heart burn, and acid regurgitation) at daytime and nighttime everyday via diary for 8 weeks. The primary endpoint is to compare the cumulated incidence of each symptom free during 8-week therapy period between the two study groups. The secondary endpoint will be the withdrawal or drop-out rate due to poor symptoms response or drug adverse effects.

Data will be analyzed with SPSS Statistical Software for descriptive statistics (percentage, mean, standard error, and 95% confidence interval) and analytical statistics (chi-square test, ANOVA, and generalized estimation equation; GEE).

Read the detailed description

We conduct a prospective randomized study since July 2017 after IRB approval. Patients between the ages of 20 and 80 years presenting to the gastroenterology outpatient clinic for atypical GERD symptoms (cough, globus, and NCCP) with or without typical symptoms (heartburn or acid regurgitation) of GERD will be invited to participate. After signing informed consents and screening, patients with atypical GERD symptoms for more than one month and with a total Reflux Symptom Index (RSI) score ≥13 were eligible for enrollment.Patients who currently took pro-kinetic agents, baclofen, antacid, sucralfate, histamin-2 receptor antagonists, PPI, antitussive, non-steroid anti-inflammatory drugs, anxiolytics, or anti-depressants or takes aforementioned medication during study period, who have severe cardiac, pulmonary, hepatic, or renal disease, who have uncured underlying malignancy, will be excluded as are subjects with laryngeal or pharyngeal disorders, a history of gastrointestinal (GI) surgery, symptoms of GI tract obstruction, or a contraindication for PPI use.

Personal characteristics including age, sex, habit of drinking and smoking, body mass index (BMI), waist circumference and underlying co-morbidity including diabetes, hypertension and dyslipidemia will be recorded. The findings of esophageal gastroduodenal scopy (EGD) will be recorded including the severity of erosive esophagitis (Los Angeles grade A-D or non-erosive reflux disease).The symptoms of atypical GERD including cough, globus sensation, and NCCP and the symptoms of typical GERD (heart burn and acid regurgitation) will be recorded everyday (daytime and night respectively) via diary before PPI therapy for 2 days and after PPI therapy for 8 weeks. The definitions of cough, globus sensation, NCCP, heart burn, and acid regurgitation will be according to a previous publication After enrollment, 120 subjects will randomly assign (at a 1:1 ratio) to receive either oral lansoprazole (Takepron OD 30 mg, Takeda Co. Ltd, Tokyo, Japan) once daily before breakfast or oral dexilansoprazole (Dexilant 60 mg, Takeda Co. Ltd, Tokyo, Japan) once daily before breakfast for 8 weeks. Subjects will record their symptoms (cough, globus, NCCP, heart burn, and acid regurgitation) at daytime and nighttime everyday for 8 weeks. Symptoms suspecting drug adverse effect including nausea, diarrhea, constipation, headache, dizziness, fatigue, flatulence, etc will be recorded for 8 weeks. Head elevation during sleeping, or on diet for body weight reduction, medication with pro-kinetic agents, baclofen, antacid, sucralfate, histamin-2 receptor antagonists, other PPI, antitussive, non-steroid anti-inflammatory drugs, anxiolytics, or anti-depressants will not be allowed during study period.

Endpoints We will evaluate the response rate (symptom free) everyday during the 8-week PPI therapy for cough, globus sensation, NCCP, acid regurgitation, and heartburn respectively. The primary endpoint is to compare the cumulated incidence and the time of each symptom free during 8-week therapy period between the two study groups. The secondary endpoint will be the withdrawal or drop-out rate due to poor symptoms response or drug adverse effects.

Exclusion criteria

Exclusion Criteria:

  1. Patients who currently took pro-kinetic agents, baclofen, antacid, sucralfate, histamin-2 receptor antagonists, PPI, antitussive, non- anti-inflammatory drugs, anxiolytics, or anti-depressants during screening and during study period

Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
