Data from a pooled post hoc analysis of 14 placebo-controlled, dapagliflozin treatment studies in patients with type 2 diabetes with and without anemia at baseline.

ABSTRACT: Dapagliflozin is a highly selective sodium-glucose cotransporter 2 inhibitor associated with stabilization of estimated glomerular filtration rate (eGFR); reductions in glycated hemoglobin (HbA1c), systolic blood pressure, body weight, and albuminuria; and a small and consistent increase in hematocrit [1], [2], [3], [4]. This data set is based on the associated article [5] analyzing data from 5325 patients with type 2 diabetes from 14 placebo-controlled, phase 3 (one phase 2/3), double-blind dapagliflozin treatment studies of 24-104 weeks' duration. Data on dapagliflozin's effects (vs. placebo) on hemoglobin (Hb), hematocrit, serum albumin, serum total protein concentrations, urine albumin/creatinine ratio, eGFR, heart rate, blood pressure, body weight, and safety in patients with type 2 diabetes with and without anemia were pooled and analyzed. Patients were divided into two groups according to baseline Hb levels: anemia (Hb <13 g/dL in men and <12 g/dL in women) and no anemia. Some biomarkers associated with erythropoiesis and the presence of anemia, such as iron, transferrin, ferritin, reticulocytes, and hepcidin, were not included in the original studies and therefore data for these biomarkers were not available. Descriptive statistics were used for baseline characteristics and safety data and a longitudinal repeated-measures mixed model for efficacy data. Changes in Hb concentrations were evaluated, and the proportion of patients with baseline anemia who were no longer anemic at week 24 was determined, as was the occurrence of polycythemia (Hb >16.5 g/dL in men and >16.0 g/dL in women). Because anemia commonly occurs in patients with diabetes and chronic kidney disease [6], the data can be of value to further analyze trends in relevant physiological and pathophysiological parameters.

Project description:Aims/hypothesisIn the Dapagliflozin and Prevention of Adverse Outcomes in Chronic Kidney Disease (DAPA-CKD) trial, dapagliflozin reduced the risks of progressive kidney disease, hospitalised heart failure or cardiovascular death, and death from all causes in patients with chronic kidney disease (CKD) with or without type 2 diabetes. Patients with more severe CKD are at higher risk of kidney failure, cardiovascular events and all-cause mortality. In this post hoc analysis, we assessed the efficacy and safety of dapagliflozin according to baseline Kidney Disease Improving Global Outcomes (KDIGO) risk categories.MethodsDAPA-CKD was a double-blind, placebo-controlled trial that randomised patients with an eGFR of 25-75 ml min-1 [1.73 m]-2 and urinary albumin/creatinine ratio (UACR) of ≥22.6 and <565.0 mg/mmol (200-5000 mg/g) to dapagliflozin 10 mg/day or placebo. The primary endpoint was a composite of ≥50% reduction in eGFR, end-stage kidney disease (ESKD), and death from a kidney or cardiovascular cause. Secondary endpoints included a kidney composite (≥50% reduction in eGFR, ESKD and death from a kidney cause), a cardiovascular composite (heart failure hospitalisation or cardiovascular death), and death from all causes. We used Cox proportional hazards regression analyses to assess relative and absolute effects of dapagliflozin across KDIGO risk categories.ResultsOf the 4304 participants in the DAPA-CKD study, 619 (14.4%) were moderately high risk, 1349 (31.3%) were high risk and 2336 (54.3%) were very high risk when categorised by KDIGO risk categories at baseline. Dapagliflozin reduced the hazard of the primary composite (HR 0.61; 95% CI 0.51, 0.72) and secondary endpoints consistently across KDIGO risk categories (all p for interaction >0.09). Absolute risk reductions for the primary outcome were also consistent irrespective of KDIGO risk category (p for interaction 0.26). Analysing patients with and without type 2 diabetes separately, the relative risk reduction with dapagliflozin in terms of the primary outcome was consistent across subgroups of KDIGO risk categories. The relative frequencies of adverse events and serious adverse events were also similar across KDIGO risk categories.Conclusion/interpretationsThe consistent benefits of dapagliflozin on kidney and cardiovascular outcomes across KDIGO risk categories indicate that dapagliflozin is efficacious and safe across a wide spectrum of kidney disease severity.Trial registrationClinicalTrials.gov NCT03036150.FundingThe study was funded by AstraZeneca.

Project description:PurposeUsing a composite endpoint, pooled data from two 12-week Phase III placebo-controlled trials (GOLDEN 3, NCT02347761; GOLDEN 4, NCT02347774) were analyzed to determine whether glycopyrrolate inhalation solution (25 mcg and 50 mcg) administered twice daily (BID) via the eFlow® Closed System nebulizer (GLY) reduced the risk of clinically important deterioration (CID) in patients with moderate-to-very-severe COPD.MethodsCID was defined as ≥100-mL decrease from baseline in post-bronchodilator trough forced expiratory volume in one second (FEV1), or ≥4-unit increase in baseline St. George's Respiratory Questionnaire (SGRQ) total score, or moderate/severe exacerbation. The relative treatment effect of GLY versus placebo on the odds of CID (any and by component endpoints) was expressed as the odds ratio (OR) and 95% confidence interval (CI). Subgroups categorized by age (<65/≥65 years), sex, smoking status (current/former), long-acting beta agonist (LABA) use, FEV1 (<50%/≥50%), and peak inspiratory flow rate (PIFR) (<60 L/min/≥60 L/min) were analyzed.ResultsCompared to placebo, GLY 25 mcg and 50 mcg BID over 12 weeks significantly reduced the risk of CID by 50% (OR: 0.50 [0.37-0.68]) and 40% (OR: 0.60 [0.44-0.80]), respectively. Subjects treated with GLY 25 mcg BID were 59% less likely to experience CID in FEV1 (OR: 0.41 [0.27-0.62]) and 48% less likely to perceive CID in health status (OR: 0.52 [0.37-0.73]). Statistically significant reductions were also observed at the higher dose. The incidence of moderate/severe exacerbations was low and comparable among the cohorts. GLY 25 mcg BID was significantly more effective than placebo (p<0.05) in preventing CID irrespective of age, smoking status, LABA use, COPD severity, or PIFR. Subjects <65 years (OR 0.45 [0.29-0.68]) and those with PIFR <60 L/min (OR 0.36 [0.20-0.67]) exhibited the largest benefit.ConclusionNebulized GLY over 12 weeks significantly reduced the risk of CID and provided greater short-term stability in patients with moderate-to-very-severe COPD.

Project description:ObjectiveTo evaluate the safety and tolerability of aripiprazole adjunctive to standard antidepressant therapy (ADT) for patients with major depressive disorder (DSM-IV-TR criteria).MethodData from 2 identical studies of aripiprazole augmentation (8 weeks of prospective ADT treatment followed by 6 weeks of randomized double-blind adjunctive treatment) were pooled. The incidence of treatment-emergent adverse events (TEAEs) and weight, electrocardiogram (ECG), and laboratory measurements were assessed during the 6-week phase, including time course, severity, resolution, and predictors. The studies were conducted from June 2004 to April 2006 and September 2004 to December 2006.ResultsThe safety analysis included 737 outpatients (aripiprazole, n = 371; placebo, n = 366). The majority of patients completed the trials (aripiprazole, 86%; placebo, 88%). Common TEAEs (≥ 5% and twice the placebo rate) with aripiprazole were akathisia (25%), restlessness (12%), insomnia (8%), fatigue (8%), blurred vision (6%), and constipation (5%). Most TEAEs were of mild to moderate severity (aripiprazole, 89%; placebo, 95%). TEAE rates in the aripiprazole and placebo groups were not affected by ADT, age, or gender. Discontinuation due to TEAEs was low (aripiprazole, 3%; placebo, 1%). Mean weight change was higher with aripiprazole versus placebo (1.73 kg vs 0.38 kg, P < .001). At endpoint, clinical laboratory parameters, vital signs, and ECG indices (including QT(c) interval) were similar between groups. Akathisia with aripiprazole generally occurred in the first 3 weeks (76%), was of mild to moderate severity (92%), and led to discontinuation in 3 patients (0.8%). Within the aripiprazole group, age (18-40 years) was the only positive predictor for akathisia.ConclusionsIn this short-term post hoc analysis, aripiprazole as augmentation to ADT demonstrated a safety and tolerability profile similar to that in monotherapy studies in other psychiatric populations. Controlled long-term safety and efficacy data of aripiprazole as adjunctive to ADT are warranted.Trial registrationclinicaltrials.gov Identifiers: NCT00095823 (CN138-139) and NCT00095758 (CN138-163).

Project description:ObjectiveEpisodes of major depressive disorder (MDD) characterized by high levels of anxiety symptoms are less likely to respond to some forms of antidepressant treatment (ADT). This report examines the effects of adjunctive brexpiprazole on depressive symptoms among patients with MDD and anxiety symptoms.Materials and methodsThis was a post hoc analysis of 1,171 patients from the 6-week, randomized, double-blind phases of three studies in adults with MDD and inadequate response to ADTs (NCT01360645, NCT01360632, NCT02196506). Data were pooled for brexpiprazole 2-3 mg/day and for placebo (adjunct to ADT). Montgomery-Åsberg Depression Rating Scale Total score changes were assessed in subgroups of patients with and without anxious distress (based on proxies for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria) and anxious depression (defined as a Hamilton Depression Rating Scale Anxiety/somatization factor score of ?7). Safety was assessed by the incidence of treatment-emergent adverse events (TEAEs).ResultsBenefits were seen for adjunctive brexpiprazole (compared with adjunctive placebo) in both anxiety definition subgroups. For patients with anxious distress, the least squares mean difference (95% CI) at week 6 was -3.00 (-4.29, -1.71; P<0.0001) and, for those without anxious distress, was -1.38 (-2.71, -0.05; P=0.043). For patients with anxious depression, the difference was -2.19 (-3.60, -0.78; P=0.0023), compared with -2.34 (-3.58, -1.10; P=0.0002) for those without anxious depression. The most common TEAEs among patients with anxiety symptoms receiving ADT + brexpiprazole were akathisia, headache, restlessness, somnolence, and weight increase. There were no clinically meaningful differences in the rates of these TEAEs according to the presence or absence of anxiety symptoms.ConclusionAdjunctive brexpiprazole 2-3 mg/day may be efficacious in reducing depressive symptoms, and was well tolerated, in patients with clinically relevant anxiety symptoms.

Project description:Introduction In the early stage of schizophrenia (first 5 years), the most important clinical target besides symptom control is relapse prevention as each relapse significantly decreases the possibility of preferable long-term outcomes. Early discontinuation of antipsychotic medication due to intolerable side-effects is one of the most common causes of relapse. Objectives This poster aims to present cariprazine’s tolerability in the early stage of schizophrenia. Methods Data from 4 randomized, double-blind, placebo-controlled trials (NCT00404573, NCT01104766, NCT01104779, NCT00694707) with similar design (1 week of wash out period, 6 weeks of treatment and 2-4 weeks of follow-up) were pooled. For the post-hoc analysis, patients with early stage of schizophrenia (defined as having a disease duration of less than 5 years) were extracted from the whole safety population, and approved doses of cariprazine (1.5-6.0 mg/day) were combined. Treatment-emergent adverse events (TEAEs) and discontinuation rates were analysed versus placebo. Results Overall, 169 placebo- (PBO) and 322 cariprazine-treated (CAR) patients were identified as having schizophrenia for less than 5 years. 67.7% cariprazine- and 56.2% placebo-treated patients reported at least one TEAE; most frequently insomnia (10.9 % CAR; 12.4% PBO), akathisia (9.6% CAR; 2.4% PBO) and extrapyramidal symptoms (9.3% CAR; 1.8% PBO). Discontinuation due to adverse events was reported in only 8.4% of cariprazine- and 14.8% of placebo-treated patients. Relapse occurred in 3.1% of cariprazine- and 5.3% of placebo-treated patients. Conclusions Cariprazine was generally well-tolerated in the early stage of schizophrenia; given the limitations of this analysis, additional research is warranted.
