Randomized clinical trial: a controlled pilot trial of the 5-HT4 receptor agonist revexepride in patients with symptoms suggestive of gastroparesis.
    Neurogastroenterology and motility, 2016, Volume: 28, Issue:4

    Gastroparesis is a chronic gastric disorder characterized by delayed gastric emptying without mechanical obstruction, and clinical symptoms as postprandial fullness, early satiety, bloating, nausea, vomiting, and abdominal pain. Prokinetic agents are used for the treatment of gastroparesis. Revexepride, a 5-hydroxytryptamine (serotonin) receptor (5-HT4 R) agonist, could be a good candidate drug for the gastroparesis treatment.. In the current phase II, exploratory, double-blind, randomized, stratified, placebo-controlled, repeated dose trial (EudraCT number 2007-004997-23), the efficacy on gastrointestinal symptoms and gastric emptying rate, safety, and pharmacokinetic profile of three oral doses of revexepride (0.02, 0.1, and 0.5 mg administered orally t.i.d. for 4 weeks) was evaluated in trial participants (diabetic and non-diabetic) with upper gastrointestinal tract symptoms suggestive for gastroparesis.. Eighty participants, enrolled in four parallel treatment groups, were asked to score their symptom diary data, gastroparesis cardinal symptom index (GCSI), patient assessment of upper gastrointestinal disorders-symptom severity index (PAGI-SYM), quality of life questionnaires, and meal-related symptom score. Gastric emptying rate was evaluated by (13) C-octanoic acid breath test.. The severity of the symptoms assessed by means of GCSI and PAGI-SYM decreased at Week 2 and decreased further at Week 4 in all treatment groups including placebo, with similar trends in all treatment groups. Quality of life improved in all treatment groups after 4 weeks of treatment. No differences on gastric emptying rate were shown between any of the active treatment groups and placebo. Revexepride was generally safe and well-tolerated.. Four weeks of revexepride treatment did not improve symptoms or gastric emptying over placebo in patients with symptoms suggestive of gastroparesis.

Randomized clinical trial: effect of the 5-HT4 receptor agonist revexepride on reflux parameters in patients with persistent reflux symptoms despite PPI treatment.
    Neurogastroenterology and motility, 2015, Volume: 27, Issue:2

    Approximately, 20-30% of patients with gastro-esophageal reflux disease (GERD) experience persistent symptoms despite treatment with proton pump inhibitors (PPIs). These patients may have underlying dysmotility; therefore, targeting gastric motor dysfunction in addition to acid inhibition may represent a new therapeutic avenue. The aim of this study was to assess the pharmacodynamic effect of the prokinetic agent revexepride (a 5-HT4 receptor agonist) in patients with GERD who have persistent symptoms despite treatment with a PPI.. This was a phase II, exploratory, multicenter, randomized, placebo-controlled, double-blind, parallel-group study in patients with GERD who experienced persistent symptoms while taking a stable dose of PPIs (ClinicalTrials.gov identifier: NCT01370863). Patients were randomized to either revexepride (0.5 mg, three times daily) or matching placebo for 4 weeks. Reflux events and associated characteristics were assessed by pH/impedance monitoring and disease symptoms were assessed using electronic diaries and questionnaires.. In total, 67 patients were enrolled in the study. There were no significant differences between study arms in the number, the mean proximal extent or the bolus clearance times of liquid-containing reflux events. Changes from baseline in the number of heartburn, regurgitation, and other symptom events were minimal for each treatment group and no clear trends were observed.. No clear differences were seen in reflux parameters between the placebo and revexepride groups.

Randomised clinical trial: the 5-HT4 agonist revexepride in patients with gastro-oesophageal reflux disease who have persistent symptoms despite PPI therapy.
    Alimentary pharmacology & therapeutics, 2015, Volume: 41, Issue:7

    A substantial proportion of patients with gastro-oesophageal reflux disease (GERD) have only a partial response to proton pump inhibitor (PPI) therapy. Prokinetic drugs may improve reflux symptoms by enhancing oesophageal motility and gastric emptying.. To evaluate the effect of revexepride, a novel prokinetic 5-hydroxytryptamine type 4 (5-HT4 ) receptor agonist, compared with placebo, in patients with GERD who have a partial response to PPIs.. A phase 2b, double-blind, parallel-group study was conducted, in which patients were randomised to one of three revexepride treatment groups (0.1, 0.5 and 2.0 mg three times daily) or placebo (1:1:1:1 ratio). Daily e-diary data captured patients' symptoms over an 8-week treatment period. The primary efficacy outcome was the weekly percentage of regurgitation-free days in the second half of the study (weeks 5-8).. In total, 480 patients were randomised and 477 received treatment (mean age 47.9 years; 61% women). The mean percentage of regurgitation-free days increased from baseline (range, 15.0-18.8%) to week 8 (62.3-70.5%) in all four study arms; however, there were no statistically significant differences in this change between placebo and the three treatment arms. No dose-dependent relationship in treatment effect was observed for any of the study endpoints. The incidence of treatment-emergent adverse events (TEAEs) was revexepride dose-dependent. Only one serious TEAE occurred and none resulted in death.. Revexepride was no more effective than placebo in controlling regurgitation in patients with GERD symptoms partially responsive to PPIs. Revexepride was well tolerated. ClinicalTrials.gov Identifier: NCT01472939.

A phase 1 randomized study evaluating the effect of omeprazole on the pharmacokinetics of a novel 5-hydroxytryptamine receptor 4 agonist, revexepride (SSP-002358), in healthy adults.
    Drug design, development and therapy, 2015, Volume: 9

    About 30% of patients with gastroesophageal reflux disease continue to experience symptoms despite treatment with proton pump inhibitors. The 5-hydroxytryptamine 4 receptor agonist revexepride (SSP-002358) is a novel prokinetic that stimulates gastrointestinal motility, which has been suggested as a continued cause of symptoms in these patients. The aim of this study was to assess whether revexepride pharmacokinetics were affected by co-administration of omeprazole, in preparation for a proof-of-concept evaluation of revexepride added to proton pump inhibitor treatment.. In this phase 1, open-label, randomized, two-period crossover study, healthy adults aged 18-55 years were given a single dose of revexepride 1 mg or revexepride 1 mg + omeprazole 40 mg. Pharmacokinetic parameters were assessed for up to 48 hours after administration of the investigational product. Adverse events, clinical chemistry and hematology parameters, electrocardiograms, and vital signs were monitored.. In total, 42 participants were enrolled and 40 completed the study. The median age was 24 years (18-54 years), 55% were women and 93% were white. The pharmacokinetic parameters of revexepride were similar without or with omeprazole co-administration. The mean area under the plasma concentration-time curve from time 0 to infinity (AUC0-∞) was 23.3 ng · h/mL (standard deviation [SD]: 6.33 ng · h/mL) versus 24.6 ng · h/mL (SD: 6.31 ng · h/mL), and maximum plasma concentrations (Cmax) were 3.89 ng/mL (SD: 1.30 ng/mL) and 4.12 ng/mL (SD: 1.29 ng/mL) in participants without and with omeprazole, respectively. For AUC0-∞ and Cmax, the 90% confidence intervals for the ratios of geometric least-squares means (with:without omeprazole) were fully contained within the pre-defined equivalence limits of 0.80-1.25. Mean apparent terminal phase half-life was 9.95 hours (SD: 2.06 hours) without omeprazole, and 11.0 hours (SD: 3.25 hours) with omeprazole.. Co-administration of the 5-hydroxytryptamine receptor 4 agonist revexepride with omeprazole did not affect the pharmacokinetics of revexepride in healthy adults.
