Zabofloxacin versus moxifloxacin in patients with COPD exacerbation: a multicenter, double-blind, double-dummy, randomized, controlled, Phase III, non-inferiority trial.

ABSTRACT: A new quinolone, zabofloxacin, has now been developed; hence, a non-inferiority trial is needed to compare this new compound with another widely used quinolone to examine its efficacy and safety for the treatment of chronic obstructive pulmonary disease (COPD) exacerbations. This was a prospective, multicenter, double-blind, double-dummy, randomized, controlled, parallel-group, Phase III, non-inferiority clinical trial designed to compare oral zabofloxacin (367 mg once daily for 5 days) with moxifloxacin (400 mg once daily for 7 days) for the treatment of patients with COPD exacerbation. In all, 345 COPD patients with a moderate COPD exacerbation were enrolled in the study via the outpatient clinics at 31 university hospitals. Clinical per protocol analysis revealed that the clinical cure rate for zabofloxacin was 86.7% and that for moxifloxacin was 86.3% (the rate difference, 0.4%; 95% confidence interval, -7.7%-8.6%). Intention-to-treat analysis revealed clinical cure rates of 77.1% and 77.3% (difference, -0.2%; 95% confidence interval, -9.0%-8.8%), respectively. These results confirm that zabofloxacin is not inferior to moxifloxacin. The favorable microbiological response rate for zabofloxacin was 67.4% and that for moxifloxacin was 79.5% (P=0.22). Patients in the zabofloxacin group showed better patient-oriented outcomes, as measured by EXAcerbations of Chronic Pulmonary Disease Tool-Patient-Reported Outcome and the COPD assessment test scores, than patients in the moxifloxacin group. Adverse drug reactions related to zabofloxacin occurred in 9.7% of cases and those related to moxifloxacin occurred in 9.6% of cases (P=0.97). The dropout rate due to adverse events was 0% (0/175) in the zabofloxacin group and 1.8% (3/167) in the moxifloxacin group (P=0.12). Oral zabofloxacin (367 mg once daily for 5 days) was not inferior to oral moxifloxacin (400 mg once daily for 7 days) for the treatment of patients with COPD exacerbation.

Project description:BackgroundThe efficacy and safety of high flow nasal therapy (HFNT) in patients with acute hypercapnic exacerbation of chronic obstructive pulmonary disease (AECOPD) are unclear. Our aim was to evaluate the short-term effect of HFNT versus NIV in patients with mild-to-moderate AECOPD, with the hypothesis that HFNT is non-inferior to NIV on CO2 clearance after 2 h of treatment.MethodsWe performed a multicenter, non-inferiority randomized trial comparing HFNT and noninvasive ventilation (NIV) in nine centers in Italy. Patients were eligible if presented with mild-to-moderate AECOPD (arterial pH 7.25-7.35, PaCO2 ≥ 55 mmHg before ventilator support). Primary endpoint was the mean difference of PaCO2 from baseline to 2 h (non-inferiority margin 10 mmHg) in the per-protocol analysis. Main secondary endpoints were non-inferiority of HFNT to NIV in reducing PaCO2 at 6 h in the per-protocol and intention-to-treat analysis and rate of treatment changes.ResultsSeventy-nine patients were analyzed (80 patients randomized). Mean differences for PaCO2 reduction from baseline to 2 h were - 6.8 mmHg (± 8.7) in the HFNT and - 9.5 mmHg (± 8.5) in the NIV group (p = 0.404). By 6 h, 32% of patients (13 out of 40) in the HFNT group switched to NIV and one to invasive ventilation. HFNT was statistically non-inferior to NIV since the 95% confidence interval (CI) upper boundary of absolute difference in mean PaCO2 reduction did not reach the non-inferiority margin of 10 mmHg (absolute difference 2.7 mmHg; 1-sided 95% CI 6.1; p = 0.0003). Both treatments had a significant effect on PaCO2 reductions over time, and trends were similar between groups. Similar results were found in both per-protocol at 6 h and intention-to-treat analysis.ConclusionsHFNT was statistically non-inferior to NIV as initial ventilatory support in decreasing PaCO2 after 2 h of treatment in patients with mild-to-moderate AECOPD, considering a non-inferiority margin of 10 mmHg. However, 32% of patients receiving HFNT required NIV by 6 h. Further trials with superiority design should evaluate efficacy toward stronger patient-related outcomes and safety of HFNT in AECOPD.Trial registrationThe study was prospectively registered on December 12, 2017, in ClinicalTrials.gov (NCT03370666).

Project description:BackgroundEchinacea has antiviral activity against influenza viruses in vitro and has traditionally been used for treatment of colds and flu.ObjectivesThis randomized, double-blind, double-dummy, multicenter, controlled clinical trial compared a new echinacea formulation with the neuraminidase inhibitor oseltamivir, the gold standard treatment for influenza.MethodsFollowing informed consent, 473 patients with early influenza symptoms (≤48 hours) were recruited in primary care in the Czech Republic and randomized to either 5 days of oseltamivir followed by 5 days of placebo, or 10 days of an Echinacea purpurea-based formulation called Echinaforce Hotdrink (A. Vogel Bioforce AG, Roggwil, Switzerland). The proportion of recovered patients (influenza symptoms rated as absent or mild in the evening) was analyzed for noninferiority between treatment groups using a generalized Wilcoxon test with significance level α = 0.05 (2-sided) and using a CI approach in the per-protocol sample.ResultsRecovery from illness was comparable in the 2 treatment groups at 1.5% versus 4.1% after 1 day, 50.2% versus 48.8% after 5 days, and 90.1% versus 84.8% after 10 days of treatment with Echinaforce Hotdrink and oseltamivir, respectively. Noninferiority was demonstrated for each day and overall (95% CI, 0.487-0.5265 by generalized Wilcoxon test). Very similar results were obtained in the group with virologically confirmed influenza virus infections and in a retrospective analysis during the peak influenza period. The incidence of complications was lower with Echinaforce Hotdrink than with oseltamivir (2.46% vs 6.45%; P = 0.076) and fewer adverse events (particularly nausea and vomiting) were observed with Echinaforce Hotdrink.ConclusionsEchinaforce Hotdrink is as effective as oseltamivir in the early treatment of clinically diagnosed and virologically confirmed influenza virus infections with a reduced risk of complications and adverse events. It appears to be an attractive treatment option, particularly suitable for self-care. Clinical trial identifier: Eudra-CT: 2010-021571-88. (Curr Ther Res Clin Exp. 2015; 77:66-72).

Project description:BackgroundPelubiprofen is a prodrug of 2-arylpropionic acid with relatively selective effects on cyclooxygenase-2 activity. The aim of this study was to compare the efficacy and safety profiles of pelubiprofen with those of celecoxib in patients with rheumatoid arthritis.MethodsThis was a 6-week, multicenter, randomized, double-blind, double-dummy, parallel-group, phase III, non-inferiority clinical trial. The primary end point was non-inferiority of pain decrease from baseline to week-6 as determined using a 100 mm pain visual analog scale (VAS). Pelubiprofen was considered non-inferior to celecoxib if the lower limit of the 97.5% confidence interval for treatment difference [(pain reduction in pelubiprofen group) - (pain reduction in celecoxib group)] was more than -10 mm. The secondary end points were as follows: non-inferiority of (1) reduction of Korean health assessment questionnaire (KHAQ) score; (2) decreased duration of morning stiffness; and (3) decrease in the frequency and total dose of rescue drugs after 6 weeks of treatment.ResultsSeventy-seven patients in the pelubiprofen group and 68 patients in the celecoxib group started the study medication. Pelubiprofen was non-inferior to celecoxib with regard to reduction in VAS pain severity (difference, mean ± SD 5.0 ± 20.1; 97.5% CI, -2.3 to ∞). Pelubiprofen was also non-inferior to celecoxib in terms of the secondary end points, such as, decrease in KHAQ score (0.0 ± 0.5, 97.5% CI -0.2 to ∞), decrease in duration of morning stiffness (median 0.0 minute in both groups), and decrease in the frequency (0.7 ± 3.5, 97.5% CI -0.6 to ∞) and total amount (0.7 ± 3.6, 97.5% CI -0.6 to ∞) of rescue medication uses during the 6 week study period. Safety analysis revealed 31.2% patients in the pelubiprofen group and 20.6% patients in the celecoxib group experienced an adverse drug reaction (ADR). The frequency of gastrointestinal ADRs was 20.8 % and 8.8%, respectively.ConclusionsPelubiprofen was found to be as effective as celecoxib at pain reduction and for relieving stiffness in RA patients. However, more patients in the pelubiprofen group experienced ADR and the frequency of gastrointestinal ADRs was higher in the pelubiprofen group. ClinialTrials.gov identifier: NCT01781702.

Project description:BackgroundTenofovir disoproxil fumarate (TDF) has been widely recommended as a first-line antiviral agent to treat chronic hepatitis B (CHB). Qingzhong and Viread, formulations of TDF commercialized by Jiangsu Chia-tai Tianqing Pharmaceutical Co Ltd and GlaxoSmithKline, respectively, have both been approved by the State Food and Drug Administration, China. This study analyzed the efficacy and safety of these 2 TDF agents in Chinese patients with CHB.MethodsIn this multicenter, randomized, double-blind, double-dummy, noninferiority phase 3 clinical trial (ClinicalTrials.gov identifier: NCT02287857), 330 Chinese patients with CHB [hepatitis B envelope antigen-positive (HBeAg) (+): 232] were randomly assigned to receive Qingzhong (group A: 161 patients) or Viread (group B: 169 patients) 300 mg once daily for 48 weeks. Subsequently, all patients were administered Qingzhong 300 mg once daily from week 49 to week 240. The primary end point was the degree of decline of plasma hepatitis B virus (HBV) DNA levels at week 48 and the secondary endpoints were viral suppression, normalization of alanine aminotransferase (ALT) levels, hepatitis B surface antigen (HBsAg)/HBeAg loss or seroconversion, and virological breakthrough.ResultsAmong patients with CHB who were HBeAg (+), the mean HBV DNA titer decreased similarly between the groups at week 48. The percentages of patients who achieved undetectable HBV DNA were similar between the groups (85.11% and 82.35% in groups A and B, respectively) and similar losses of HBeAg and HBeAg seroconversion rates were achieved. Moreover, for patients with CHB who were HBeAg (-), reductions in HBV DNA were similar. Among all patients with CHB, the rates of normalization of ALT and the loss of HBsAg were similar. The overall incidence of adverse events was comparable between the groups.ConclusionIn conclusion, the 48-week administration of Qingzhong showed noninferior efficacy and safety profiles compared to Viread in Chinese patients with CHB.
