Tolerability and efficacy of glycemic control with saxagliptin in older patients (aged ? 65 years) with inadequately controlled type 2 diabetes mellitus.

ABSTRACT: To assess safety and efficacy of saxagliptin in older patients with type 2 diabetes mellitus (T2DM).This was a post hoc analysis of pooled data from older patients (?65 years of age) from five 24-week phase III trials: three studies of saxagliptin versus placebo as an add-on therapy to metformin, glyburide, or a thiazolidinedione; and two studies of saxagliptin versus placebo as monotherapy in drug-naïve patients. Separate analyses were conducted on one study of initial combination therapy with saxagliptin plus metformin versus metformin monotherapy in drug-naïve patients. The safety analysis population for the five-study pool included 428 patients ? 65 years of age with baseline glycated hemoglobin (HbA(1c)) 7.0% to 10.5% who received saxagliptin 2.5 or 5 mg or placebo, and for the study of initial combination therapy included 69 patients ? 65 years of age with baseline HbA(1c) 8.0% to 12.0% who received saxagliptin 5 mg in combination with metformin or metformin monotherapy. The primary efficacy endpoint was change from baseline HbA(1c).In the five-study pool, the differences in the adjusted mean change from baseline HbA(1c) among older patients receiving saxagliptin versus placebo were -0.60% (95% confidence interval [CI], -0.99% to -0.21%) for saxagliptin 2.5 mg and -0.55% (-0.97% to -0.14%) for saxagliptin 5 mg; in the initial combination study, the difference was -1.22% (-2.27% to -0.17%) among older patients receiving saxagliptin 5 mg plus metformin versus metformin monotherapy. The results were generally similar in older and younger patients. Saxagliptin was well tolerated; the incidence and types of adverse events were similar for saxagliptin and comparators. Hypoglycemia was reported in 3.0% to 9.4% of patients receiving saxagliptin (0%-8.0% for comparators) and was confirmed (finger stick glucose ? 50 mg/dL, with associated symptoms) in 0% to 0.7% (0%-0.7% for comparators); hypoglycemic episodes did not vary by age category and did not require medical intervention.Saxagliptin was effective and well tolerated, with a low risk of hypoglycemia, when used as monotherapy, add-on therapy, or initial combination therapy with metformin in older patients with T2DM.

Project description:BackgroundTreatment 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.MethodsPooled 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).ResultsA 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).ConclusionSaxagliptin 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:BACKGROUND:The incidence of epilepsy is high within the first few years of life, stabilizes over the second through fifth decades, and then rises again. Treatment of elderly patients with antiepileptic drugs (AEDs) is complicated by increased sensitivity to drug effects, altered pharmacokinetics and an increased risk for drug interactions due to polytherapy. On the other hand, the safety and efficacy data of AEDs attained during clinical development programmes are relatively limited for this age group. OBJECTIVE:The aim of this study was to evaluate the safety, tolerability and efficacy of eslicarbazepine acetate (ESL) as adjunctive therapy in patients aged???65 years with focal-onset seizures (FOS). METHODS:This was an international, multicentre, open-label, non-controlled, single-arm, post-European approval commitment study with flexible doses of ESL between 400 and 1200 mg/day. Seventy-two elderly patients with at least two FOS in the prior 4 weeks, and treated with one or two AEDs, were enrolled. The study consisted of an 8-week baseline, followed by a 26-week treatment period during which the investigator was allowed to up- or down-titrate the ESL dose, and a 4-week follow-up period. Safety and tolerability were assessed as well as mental sedation, cognitive mental state and suicidal ideation. Efficacy was assessed based on patient diaries regarding the absolute and relative changes in seizure frequency, change in intellectual impairment and quality of life. RESULTS:Overall, 47 (65.3%) patients experienced 152 treatment-emergent adverse events (TEAEs). The most frequent were dizziness (12.5%), somnolence (9.7%), fatigue, convulsion and hyponatraemia (8.3% each). All patients that experienced hyponatraemia (6/72) recovered without sequelae. Three patients died during the study (due to cardiac failure, glioblastoma multiforme and ischaemic stroke, all considered unrelated to ESL). Overall, 16 (22.2%) patients discontinued prematurely due to TEAEs. The incidences of clinically significant findings were low for vital signs, ECG, physical and neurological examinations. No TEAEs of hypothyroidism were reported; however, 24 (33.3%) patients presented post-baseline shifts from normal to decreased free T4 levels (not clinically significant). ESL decreased standardized seizure frequency from a mean of 4.8 seizures at baseline to 3.6 seizures at endpoint (p?>?0.05); and mean number of days with seizures significantly decreased from 4.1 (baseline) to 2.8 at endpoint (p?=?0.0408). CONCLUSION:ESL taken once daily (400-1200 mg) as adjunctive therapy in patients aged???65 years was found to be safe, well tolerated and efficacious (EudraCT number: 2009-012587-14).

Project description:ObjectiveTo evaluate the safety and efficacy of intravenous golimumab + methotrexate (MTX) in patients with active rheumatoid arthritis (RA) aged < 65 years and those ≥ 65 years who were enrolled in the GO-FURTHER study.MethodsIn the phase III, double-blind, randomized, placebo-controlled GO-FURTHER trial, patients with active RA were randomized to intravenous (IV) golimumab 2 mg/kg + MTX or placebo + MTX at weeks 0 and 4, then every 8 weeks thereafter (with crossover to golimumab at week 16 [early escape] or week 24 [per-protocol]). The final golimumab infusion was at week 100. Assessments included American College of Rheumatology (ACR) 20/50/70 response criteria. Efficacy and adverse events (AEs) were monitored through 2 years. Efficacy and AEs were summarized for patients aged < 65 years or ≥ 65 years; AEs were also summarized for patients < or ≥ 70 years and patients < or ≥ 75 years.ResultsIn GO-FURTHER, 592 patients were randomized to receive placebo (n = 197) or golimumab (n = 395), 515 were aged < 65 years and 77 were ≥ 65 years. At week 24, ACR20 response rates were greater for golimumab + MTX patients compared with placebo + MTX for patients < 65 years (61.6% vs 31.3%, p < 0.001) and those ≥ 65 years (69.5% vs 33.3%; p < 0.01). Infections were the most common AE through week 112 (51.6% in patients < 65 years; 55.3% in patients ≥ 65 years); upper respiratory infections were the most common infection in patients < 65 years (13.2%) and those ≥ 65 years (11.8%). Serious AEs occurred in 17.7% in patients < 65 years and 25.0% of patients ≥ 65 years and included malignancies, pneumonia, fractures, acute pancreatitis, cellulitis, and bacterial arthritis.ConclusionsIn GO-FURTHER, ACR response rates were similar between patients < 65 years and patients ≥ 65 years within each treatment group. AEs in elderly patients were similar to the known safety profile of IV golimumab. Immunosenescence is known to increase the risk of infections in the elderly. Elderly patients had a numerically higher incidence of serious infections. Six malignancies occurred in golimumab-treated patients, all in patients < 65 years.Trial registrationclinicaltrials.gov: NCT00973479 . Registered September 9, 2009.
