Efficacy of S-pantoprazole 10 mg in the Symptom Control of Non-erosive Reflux Disease: A Phase III Placebo-controlled Trial.

ABSTRACT:

Background/aims

S-isomer (S) pantoprazole is more bioavailable and less dependent on cytochrome 2C19 than is racemic pantoprazole. We aim to evaluate the efficacy and safety of 10 mg S-pantoprazole for treatment of non-erosive reflux disease (NERD).

Methods

In this phase 3, double-blind, randomized placebo controlled, multicenter study, 174 NERD patients were randomized to one of both treatment groups: 10 mg S-pantoprazole, or placebo once daily for 4 weeks. Symptoms and safety were assessed. The efficacy endpoints were complete relief of symptoms, > 50% improvement of all reflux symptoms and recurrence.

Results

Eighty-eight patients were assigned to the S-pantoprazole group (25 males, mean 43.7 years old) and 86 to the placebo group (32 males, mean 43.0 years old), and 163 patients were subjected to full Analysis Set. A higher proportion of patients in the S-pantoprazole group had complete symptom relief (42.0 % [34/81] vs 17.1% [14/82], P < 0.001) and > 50% symptom responses (66.0% vs 50.0%, P = 0.010 for heartburn; 64.2% vs 28.0%, P = 0.010 for acid regurgitation; and 51.9% vs 30.5%, P = 0.03 for epigastric discomfort) compared to the placebo group. The factors associated with poor responsiveness to PPI were older age, female, greater body mass index, and severe baseline symptoms.

Conclusions

Low dose of S-pantoprazole (10 mg) for 4 weeks was more efficacious than placebo in providing reflux symptom relief in patients with NERD, especially acid regurgitation. More doses or longer periods of treatment with S-pantoprazole would be needed to completely eliminate symptoms.

Project description:IntroductionProton pump inhibitors therapy success in the treatment of gastroesophageal reflux disease (GERD) is a difficult task because the extent of mucosal damage has no relation with the severity of the symptoms.AimTo establish the efficacy of pantoprazole treatment in patients with erosive reflux disease (ERD) and in those with non-erosive reflux disease (NERD), by assessing symptom relief and quality of life. Treatment duration and adverse events associated with pantoprazole treatment were analysed.Material and methodsThis meta-analysis was based on three multicentre, prospective, open-label, phase IV trials conducted in Slovenia, Poland, and the Russian Federation. In total, 252 patients with GERD were included and treated with pantoprazole 40 mg once daily for 4 or 8 weeks, depending on the fulfilment of predefined healing criteria. Symptoms were assessed by patients on a scale from 0 to 3 and the quality of life on a rating scale from 1 to 10.ResultsForty-five percent of patients fulfilled the healing criteria after 4 weeks of treatment, and 70% of patients after 8 weeks of treatment. Patients who failed to reach the healing criteria reported significant reduction of symptoms severity. The response to 8-week treatment was significantly higher in patients with ERD (76%) when compared to patients with NERD (64%). Discontinuation of treatment after 4 weeks was not associated with worsening of symptoms and did not affect quality of life. Pantoprazole treatment was associated with improvement of symptoms and the quality of life of GERD patients over 8 weeks of treatment and showed that GERD patients with persisting symptoms benefit from prolonging treatment to 8 weeks. Treatment with pantoprazole 40 mg was very well tolerated - more than 90% of patients were without adverse events throughout the whole study and only 4 patients discontinued the treatment due to adverse events related to pantoprazole treatment.ConclusionsPantoprazole 40 mg was associated with complete relief of GERD-related symptoms in the majority of patients with ERD and NERD. Furthermore, the severity of symptoms was significantly reduced in patients without complete relief of symptoms. Pantoprazole also continuously improved the quality of life of GERD patients over 8 weeks of treatment and was very well tolerated throughout the whole study. Therefore, this meta-analysis suggests that pantoprazole 40 mg once daily is an effective and well-tolerated choice for providing symptom relief of patients with GERD.

Project description:BackgroundWe compared the efficacy and safety of low-intensity atorvastatin and ezetimibe combination therapy with moderate-intensity atorvastatin monotherapy in patients requiring cholesterol-lowering therapy.MethodsAt 19 centers in Korea, 290 patients were randomized to 4 groups: atorvastatin 5 mg and ezetimibe 10 mg (A5E), ezetimibe 10 mg (E), atorvastatin 5 mg (A5), and atorvastatin 10 mg (A10). Clinical and laboratory examinations were performed at baseline, and at 4-week and 8-week follow-ups. The primary endpoint was percentage change from baseline in low-density lipoprotein (LDL) cholesterol levels at the 8-week follow-up. Secondary endpoints included percentage changes from baseline in additional lipid parameters.ResultsBaseline characteristics were similar among the study groups. At the 8-week follow-up, percentage changes in LDL cholesterol levels were significantly greater in the A5E group (49.2%) than in the E (18.7%), A5 (27.9%), and A10 (36.4%) groups. Similar findings were observed regarding the percentage changes in total cholesterol, non-high-density lipoprotein cholesterol, and apolipoprotein B levels. Triglyceride levels were also significantly decreased in the A5E group than in the E group, whereas high-density lipoprotein levels substantially increased in the A5E group than in the E group. In patients with low- and intermediate-cardiovascular risk, 93.3% achieved the target LDL cholesterol levels in the A5E group, 40.0% in the E group, 66.7% in the A5 group, and 92.9% in the A10 group. In addition, 31.4% of patients in the A5E group, 8.1% in E, 9.7% in A5, and 7.3% in the A10 group reached the target levels of both LDL cholesterol < 70 mg/dL and reduction of LDL ≥ 50% from baseline.ConclusionsThe addition of ezetimibe to low-intensity atorvastatin had a greater effect on lowering LDL cholesterol than moderate-intensity atorvastatin alone, offering an effective treatment option for cholesterol management, especially in patients with low and intermediate risks.

Project description:BackgroundFor many patients, current treatments do not adequately resolve heartburn in nonerosive reflux disease (NERD).ObjectiveTo compare vonoprazan and placebo with respect to the frequency and severity of heartburn in patients with NERD.MethodsThis Phase III, double-blind, placebo-controlled, parallel-group, multicenter study included patients in Japan aged ≥20 years with Grade N or M NERD and recurrent acid reflux symptoms. Patients were blinded and randomized 1:1:1 to receive placebo or vonoprazan 10 mg or 20 mg. The primary efficacy outcome was the proportion of days without heartburn measured by patient scores during the 4-week treatment period.ResultsEight hundred twenty-seven patients were randomized (placebo: n = 278, vonoprazan 10 mg: n = 278, and vonoprazan 20 mg: n = 271). Median proportion of days without heartburn was 7.4% (placebo), 10.3% (vonoprazan 10 mg), and 12.0% (vonoprazan 20 mg). Proportion of days without heartburn was not statistically significant between the vonoprazan and placebo groups (P = 0.2310 [10 mg] and P = 0.0504 [20 mg]). Mean severity of heartburn was significantly higher with placebo (median score = 1.070) than with vonoprazan 10 mg (median score = 0.990; P = 0.0440) and 20 mg (median score = 0.960; P = 0.0139). Patients whose symptoms improved at Week 2 experienced significantly increased proportion of days without heartburn and reduced mean severity of heartburn at Week 4 with vonoprazan compared with placebo (proportion of days without heartburn: P = 0.0004 [10 mg] and P = 0.0001 [20 mg] and mean severity: P < 0.0001 [10 mg] and P < 0.0001 [20 mg]). A significant difference in median proportion of days without heartburn was observed for vonoprazan 20 mg compared with placebo in patients with Grade M NERD. Incidence of treatment-emergent adverse events was 32.7% (placebo), 27.7% (vonoprazan 10 mg), and 28.0% (vonoprazan 20 mg).ConclusionsVonoprazan at doses of 10 mg and 20 mg are not superior to placebo with respect to proportion of days without heartburn, whereas the mean severity of heartburn is lower with vonoprazan compared with placebo in patients with NERD.
