Long-term safety and tolerability of valsartan in children aged 6 to 17 years with hypertension.

ABSTRACT: OBJECTIVE:The present study aimed to assess the long-term safety and tolerability of valsartan in hypertensive children aged 6-17 years, with or without chronic kidney disease (CKD). METHODS:This was an 18-month, open-label, multicentre, prospective study conducted in 150 patients with history of hypertension with or without CKD. The primary endpoint was long-term safety and tolerability of valsartan and valsartan-based treatments, assessed in terms of adverse events (AEs), serious AEs, laboratory measurements, estimated glomerular filtration rate (eGFR), urinalysis and electrocardiogram. RESULTS:Of 150 enrolled patients, 117 (78%) completed the study. At week 78, a clinically and statistically significant reduction in mean sitting systolic and diastolic blood pressures was observed in all patients (-?14.9 mmHg and -?10.6 mmHg, respectively). Within the first 3 months of treatment, mean urine albumin creatinine ratio decreased in CKD population, which was sustained. A higher percentage of CKD patients had at least one AE compared to non-CKD patients (85.3% vs. 73.3%, respectively). The majority of AEs were mild (50.7%) or moderate (18.7%) in severity. As expected, in patients with underlying CKD, increases in serum potassium, creatinine and blood urea nitrogen were more commonly reported compared to non-CKD patients. A >?25% decrease in Schwartz eGFR was observed in 28.4% of CKD patients and 13.5% of non-CKD patients. CONCLUSIONS:Valsartan was generally well tolerated, with an AE profile consistent with angiotensin receptor blockers in the overall population and in patients with underlying CKD. Long-term efficacy was maintained and a beneficial effect on proteinuria was observed.

Project description:Treatment decisions for older patients with type 2 diabetes mellitus must balance glycemic control and adverse event risk. The objective of this study was to evaluate the long-term safety and tolerability of saxagliptin 5 mg as add-on therapy to common antihyperglycemic drugs in patients aged ? 65 years and <65 years.Pooled adverse event data from three placebo-controlled trials of 76-206 weeks' duration in older (? 65 years) and younger (<65 years) patients receiving saxagliptin 5 mg or matching placebo added to metformin, glyburide, or a thiazolidinedione were analyzed. Measurements were calculated from day of first dose to specified event or last dose and included time at risk for adverse events, treatment-related adverse events, serious adverse events, adverse events leading to discontinuation, and events of special interest. Weighted incidence rates (number of events/total time) and incidence rate ratios (saxagliptin/placebo) with 95% confidence intervals were calculated (Mantel-Haenszel test).A total of 205 older (mean age 69 years; saxagliptin, n=99; placebo, n=106) and 1,055 younger (mean age 52 years; saxagliptin, n=531; placebo, n=524) patients were assessed. Regardless of age category, the adverse event incidence rates were generally similar between treatments, with confidence intervals for incidence rate ratios bridging 1. Treatment-related adverse events occurred in 36 older patients receiving saxagliptin versus 32 receiving placebo (incidence rate 34.1 versus 27.1 per 100 person-years) and in 150 younger patients in both treatment groups (incidence rate 24.0 versus 27.8 per 100 person-years). With saxagliptin versus placebo, serious adverse events occurred in eight versus 14 older (incidence rate 5.7 versus 9.9 per 100 person-years) and 49 versus 44 younger patients (incidence rate 6.5 versus 6.6 per 100 person-years). There were two deaths (one patient ? 65 years) with saxagliptin and six (none aged ? 65 years) with placebo. Older patients rarely experienced symptomatic confirmed hypoglycemia (fingerstick glucose ? 50 mg/dL; saxagliptin, n=1; placebo, n=2).Saxagliptin add-on therapy was generally well tolerated in older patients aged ? 65 years with type 2 diabetes mellitus, with a long-term safety profile similar to that of placebo.

Project description:The purpose of this study was to evaluate the short- and long-term efficacy and safety of ziprasidone in children and adolescents with bipolar I disorder.Subjects 10-17 years of age with a manic or mixed episode associated with bipolar I disorder participated in a 4 week, randomized, double-blind, placebo-controlled multicenter trial (RCT) followed by a 26 week open-label extension study (OLE). Subjects were randomized 2:1 to initially receive flexible-dose ziprasidone (40-160 mg/day, based on weight) or placebo. Primary outcome was the change in Young Mania Rating Scale (YMRS) scores from baseline. Safety assessments included weight and body mass index (BMI), adverse events (AEs), vital signs, laboratory measures, electrocardiograms, and movement disorder ratings.In the RCT, 237 subjects were treated with ziprasidone (n=149; mean age, 13.6 years) or placebo (n=88; mean age, 13.7 years). The estimated least squares mean changes in YMRS total (intent-to-treat population) were -13.83 (ziprasidone) and -8.61 (placebo; p=0.0005) at RCT endpoint. The most common AEs in the ziprasidone group were sedation (32.9%), somnolence (24.8%), headache (22.1%), fatigue (15.4%), and nausea (14.1%). In the OLE, 162 subjects were enrolled, and the median duration of treatment was 98 days. The mean change in YMRS score from the end of the RCT to the end of the OLE (last observation carried forward) was -3.3 (95% confidence interval, -5.0 to -1.6). The most common AEs were sedation (26.5%), somnolence (23.5%), headache (22.2%), and insomnia (13.6%). For both the RCT and the OLE, no clinically significant mean changes in movement disorder scales, BMI z-scores, liver enzymes, or fasting lipids and glucose were observed. One subject on ziprasidone in the RCT and none during the OLE had Fridericia-corrected QT interval (QTcF) ? 460 ms.These results demonstrate that ziprasidone is efficacious for treating children and adolescents with bipolar disorder. Ziprasidone was generally well tolerated with a neutral metabolic profile.NCT00257166 and NCT00265330 at ClinicalTrials.gov.

Project description:IntroductionIn the event-driven GRIPHON randomised-controlled trial, the oral prostacyclin receptor agonist selexipag significantly reduced the risk of disease progression (composite primary endpoint of morbidity/mortality), compared with placebo, in patients with pulmonary arterial hypertension (PAH). The ongoing open-label extension study (GRIPHON OL) collects further data on long-term safety, tolerability, and survival of PAH patients treated with selexipag.MethodsPatients randomised to selexipag or placebo in GRIPHON could enter GRIPHON OL either after experiencing a morbidity event during double-blind treatment or at the end of the study. Patients were followed for adverse events (AE) and survival from selexipag initiation up to 3 days and 30 days after end of treatment, respectively. Data are presented up to a cut-off date of 1 September 2019.ResultsOverall, 953 patients in GRIPHON and GRIPHON OL were treated with selexipag. At the time of selexipag initiation, 81.2% of patients were receiving background PAH therapy. Median (min, max) exposure to selexipag was 31.7 months (0, 106), corresponding to a total of 3054.4 patient-years. The most frequently reported AEs were related to known prostacyclin-related effects or underlying disease. There were 305 (32.0%) patients who experienced an AE leading to treatment discontinuation. Survival during GRIPHON and GRIPHON OL was assessed for the 574 patients randomised to selexipag in GRIPHON. Kaplan-Meier survival estimates (95%CI) at 1, 3, 5 and 7 years were 92.0% (89.4, 94.0), 79.3% (75.4, 82.6), 71.2% (66.5, 75.3) and 63.0% (57.4, 68.1), respectively.ConclusionsThese results provide the longest follow-up period published to date for a PAH therapy. The safety profile of selexipag over this extended treatment period was consistent with that observed in GRIPHON. A large proportion of the population was receiving background therapy at selexipag initiation, providing further insight into the long-term safety of selexipag as part of a combination therapy regimen.Trial registrationClinicalTrials.gov Identifiers: NCT01106014 and NCT01112306.

Project description:BackgroundRandomised controlled trials have evaluated the recombinant tetravalent dengue vaccine (CYD-TDV). However, individual results may have little power to identify differences among the populations studied.ObjectiveTo evaluate efficacy, immunogenicity and safety of CYD-TDV in the prevention of dengue in children aged 2-17 years.DesignSystematic review and meta-analysis.Data sourcesMEDLINE (from 1950 to 5 December 2018), EMBASE (from 1947 to 5 December 2018) and Cochrane (from 1993 to 5 December 2018).Eligibility criteria of studiesRandomised trials comparing efficacy, immunogenicity and safety of CYD-TDV with placebo or other vaccines for preventing dengue cases in children aged 2-17 years.Outcome measuresEfficacy, immunogenicity and safety of CYD-TDV.Study appraisal and methodsCalculations were made of relative risk (RR) and mean difference (MD) for dichotomous and continuous outcomes, respectively. All estimates were calculated considering a 95% CI estimate. A p<0.05 was considered statistically significant.ResultsNine studies involving 34 248 participants were included. The overall efficacy of CYD-TDV was 60% (RR 0.40 (0.30 to 0.54)). Serotype-specific efficacy of the vaccine was 51% for dengue virus type-1 (DENV-1) (RR 0.49 (0.39 to 0.63)); 34% for DENV-2 (RR 0.66 (0.50 to 0.86)); 75% for DENV-3 (RR 0.25 (0.18 to 0.35)) and 77% for DENV-4 (RR 0.23 (0.15 to 0.34)). Overall immunogenicity (MD) of CYD-TDV was 225.13 (190.34 to 259.93). Serotype-specific immunogenicity was: DENV-1: 176.59 (123.36 to 229.83); DENV-2: 294.21 (181.98 to 406.45); DENV-3: 258.78 (146.72 to 370.84) and DENV-4: 189.35 (141.11 to 237.59). The most common adverse events were headache and pain at the injection site.LimitationsThe main limitation of this study was unclear or incomplete data.Conclusions and implications of key findingsCYD-TDV is considered safe and able to partially protect children and adolescents against four serotypes of DENV for a 1-year period. Despite this, research should prioritise improvements in vaccine efficacy, thus proving higher long-term protection against all virus serotypes.Prospero registration numberCRD42016043628.
