Abstract
BACKGROUND: In numerous clinical trials, proton pump inhibitors have demonstrated potent acid suppression and healing of erosive oesophagitis, as well as successful symptom relief for the entire spectrum of gastro-oesophageal reflux disease. AIM: The 'Future of Acid Suppression Therapy' (FAST) trial evaluated, in actual clinical practice, the timing of symptom relief, changes in symptom severity, health-related quality of life and safety in endoscopically confirmed erosive gastro-oesophageal reflux disease treated with rabeprazole. METHODS: This open-label, multicentre study enrolled 2579 patients to receive rabeprazole treatment using 20 mg once daily for 8 weeks. Between two clinical visits (at enrollment and week 8), patients used an interactive voice response system to rate gastro-oesophageal reflux disease symptoms. Subgroup analyses of efficacy were conducted for gender, age, Hetzel-Dent grade, presence of Barrett's oesophagus and for patients reporting previously ineffective symptom relief with omeprazole or lansoprazole. RESULTS: On day 1, rabeprazole significantly decreased daytime and night-time heartburn severity, regurgitation and belching. Complete relief of daytime and night-time heartburn was achieved in 64.0% and 69.2% of symptomatic patients, respectively, on day 1, and in 81.1% and 85.7% of patients, respectively, on day 7. Patients with moderate or severe heartburn symptoms at baseline achieved an even greater degree of satisfactory symptom relief (none or mild) from day 1 onwards. The median time to satisfactory heartburn relief was 2 days. Subgroup analyses showed no consistent differences in efficacy compared to the overall population treated. Health-related quality of life in patients was significantly lower than that of the US general population and improved significantly after 8 weeks of rabeprazole therapy. Rabeprazole was well tolerated, with headache as the most common adverse event, reported by less than 2% of the study population. CONCLUSIONS: In this large, open-label trial, rabeprazole rapidly and effectively relieved gastro-oesophageal reflux disease symptoms in most patients with erosive oesophagitis. Substantial symptom relief was noted on day 1; improvement continued over the first week and at week 4. By week 8, the health-related quality of life had also improved vs. baseline.
