Introduction Dapagliflozin treatment when added to insulin therapy in Japanese patients with type 2 diabetes remains to be evaluated. Materials and Methods This was a multicenter, randomized, double‐blind, parallel‐group, placebo‐controlled study to evaluate efficacy (at 16 weeks) and long‐term safety (at 52 weeks) of dapagliflozin in addition to insulin therapy. The interim analysis was carried out at week 16 to assess the efficacy and safety profiles. The patients receiving insulin (n = 182) were randomized to either dapagliflozin 5 mg or a placebo at a 2:1 ratio. The primary efficacy end‐point was the change in hemoglobin A1c (HbA1c) from baseline at week 16. Results Patients in the dapagliflozin group showed an adjusted decrease in HbA1c of −0.55% from baseline, whereas the placebo showed a marginal increase of 0.05%. The placebo‐corrected mean change of HbA1c from baseline to week 16 in dapagliflozin was −0.60% (P < 0.0001). In addition, the placebo‐corrected mean change of fasting plasma glucose and bodyweight from baseline to week 16 in the dapagliflozin group was −22.7 mg/dL (P < 0.0001) and −1.21 kg (P < 0.0001), respectively. The placebo‐corrected mean daily insulin dose in the dapagliflozin group was numerically decreased (treatment difference: −0.72 IU/day; P = 0.0743). No major episodes or discontinuations as a result of hypoglycemia were reported during the study period. Conclusions Dapagliflozin used as add‐on treatment to insulin therapy showed significantly greater reduction of HbA1c, fasting plasma glucose and bodyweight without severe hypoglycemia compared with the placebo at week 16. These results show the clinical benefit of prescribing dapagliflozin for Japanese patients with insufficient glycemic control even with insulin therapy.

IntroductionUncontrolled asthma is associated with substantial morbidity. While fast-acting bronchodilators provide quick relief from asthma symptoms, their use as rescue fails to address the underlying inflammation. Combining a short-acting beta2-agonist, such as albuterol (salbutamol), with an inhaled corticosteroid, such as budesonide, in a single inhaler as rescue therapy could help control both bronchoconstriction and inflammation, and reduce the risk of asthma exacerbations.Methods and analysisThe Phase 3 MANDALA study was designed to determine the efficacy of albuterol in combination with budesonide (albuterol/budesonide 180/160 µg or 180/80 µg, two actuations of 90/80 µg or 90/40 µg, respectively) versus albuterol (180 µg, two actuations of 90 µg) as rescue therapy in adult, adolescent and paediatric patients with moderate-to-severe asthma. This event-driven study enrolled symptomatic patients (3000 adults/adolescents and 100 children aged 4–11 years) who experienced ≥1 severe asthma exacerbation in the previous year and were receiving maintenance therapy for ≥3 months prior to study entry. The primary efficacy endpoint was time-to-first severe asthma exacerbation.Ethics and disseminationThe study was conducted in accordance with the ethical principles that have their origin in the Declaration of Helsinki, and that are consistent with International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use and Good Clinical Practice and the applicable regulatory requirements.Trial registrationNCT03769090.

Introduction We assessed effects of AZD7442 (tixagevimab/cilgavimab) on deaths from any cause or hospitalizations due to coronavirus disease 2019 (COVID-19) and symptom severity and longer-term safety in the TACKLE adult outpatient treatment study. Methods Participants received 600 mg AZD7442 ( n  = 452) or placebo ( n  = 451) ≤ 7 days of COVID-19 symptom onset. Results Death from any cause or hospitalization for COVID-19 complications or sequelae through day 169 (key secondary endpoint) occurred in 20/399 (5.0%) participants receiving AZD7442 versus 40/407 (9.8%) receiving placebo [relative risk reduction (RRR) 49.1%; 95% confidence interval (CI) 14.5, 69.7; p  = 0.009] or 50.7% (95% CI 17.5, 70.5; p  = 0.006) after excluding participants unblinded before day 169 for consideration of vaccination). AZD7442 reduced progression of COVID-19 symptoms versus placebo through to day 29 (RRR 12.5%; 95% CI 0.5, 23.0) and improved most symptoms within 1–2 weeks. Over median safety follow-up of 170 days, adverse events occurred in 174 (38.5%) and 196 (43.5%) participants receiving AZD7442 or placebo, respectively. Cardiac serious adverse events occurred in two (0.4%) and three (0.7%) participants receiving AZD7442 or placebo, respectively. Conclusions AZD7442 was well tolerated and reduced hospitalization and mortality through 6 months, and symptom burden through 29 days, in outpatients with mild-to-moderate COVID-19.

Graphical Abstract Plain Language Summary Antibodies are proteins produced by the body’s immune system to specifically combat foreign substances, such as viruses. Tixagevimab and cilgavimab are a pair of antibodies that bind to a specific part of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19). When they bind to the virus, they reduce its ability to cause disease. These antibodies were tested in a clinical trial to see if they could prevent people with COVID-19 from being hospitalized or dying. Around 900 adults took part in this clinical trial. These people all had COVID-19 but were not sick enough to be in hospital. Half of this group were treated with a dose of tixagevimab and cilgavimab, given as two injections. The other half received a placebo (injections that look exactly like the tixagevimab and cilgavimab injections but contain no medicine). The study found that, over 6 months, people with COVID-19 who received tixagevimab and cilgavimab were less likely to need to go to hospital than people who received the placebo. They were also less likely to die of COVID-19. Tixagevimab and cilgavimab also helped to improve COVID-19 symptoms. People who received the antibodies saw their symptoms improve faster than people who received the placebo. They were also less likely to have symptoms that got worse. Most people felt better within 1–2 weeks of getting treatment. No safety issues were found with tixagevimab and cilgavimab compared with placebo.

Among patients with moderate-to-severe asthma who were receiving a range of inhaled glucocorticoid maintenance therapies, the risk of severe asthma exacerbation was significantly lower with as-needed use of a fixed-dose combination of 180 μg of albuterol and 160 μg of budesonide than with albuterol alone.

Background A pre-specified meta-analysis of cardiovascular (CV) events from 21 phase 2b/3 dapagliflozin clinical trials was undertaken to characterise the CV profile of dapagliflozin. This showed no increase in CV risk with dapagliflozin compared with control (placebo or comparator treatment) with or without background glucose-lowering therapies. The analysis reported here aimed to characterise the CV profile of dapagliflozin in subgroups of patients in these 21 studies grouped by degree of CV risk, based on both baseline and in-study risk factors (including hypoglycaemic events), with a focus on major adverse CV events (MACE). Methods Patients with type 2 diabetes, both overall and with different levels of CV risk, including CV disease (CVD) history, age and other CV risk factors, were analysed. A further analysis compared CV risk in patients who experienced a hypoglycaemic event prior to MACE and those who did not. Analyses were based on time to first event using a Cox proportional hazards model stratified by study comparing dapagliflozin versus control. Results In total, 9339 patients were included in this meta-analysis; 5936 patients received dapagliflozin 2.5–10 mg (6668 patient–years) and 3403 received control (3882 patient–years). Dapagliflozin is not associated with increased CV risk and results further suggest the potential for a beneficial effect both in the overall population [Hazard Ratio (HR) 0.77; 95 % CI (0.54, 1.10) for MACE] and in those with a history of CVD [HR 0.80 (0.53, 1.22)]. These findings were consistent in patients with varying degrees of CV risk, including age, number and type of CVD events in medical history and number of CV risk factors present. Furthermore, there was no increased risk of MACE in patients who experienced a hypoglycaemic event compared with those who did not. Conclusions There was no suggestion of increased risk for MACE with dapagliflozin compared with control in any of the populations investigated. In addition, the results suggest the potential for a beneficial CV effect which is consistent with the multifactorial benefits on CV risk factors associated with sodium–glucose cotransporter-2 (SGLT2) inhibitors.

Abstract Context Combining a sodium-glucose cotransporter 2 inhibitor with a xanthine oxidase inhibitor (XOI) and a urate transporter 1 (URAT1) inhibitor may enhance serum uric acid (sUA) lowering. However, concerns exist regarding high urinary UA (uUA) excretion rates and subsequent crystallization in renal tubules. Objective To assess whether dapagliflozin added to verinurad, a selective URAT1 inhibitor, and febuxostat, an XOI, increases uUA excretion. Design Randomized, placebo-controlled, 2-way crossover study (NCT03316131). Patients Adults with asymptomatic hyperuricemia. Interventions Subjects (N = 36) were randomized to oral once-daily 9 mg verinurad plus 80 mg febuxostat plus 10 mg dapagliflozin for 7 days and 7 days of oral once-daily 9 mg verinurad plus 80 mg febuxostat plus placebo with an intervening 7- to 21-day washout period. Main Outcome Measure Difference in peak uUA excretion between groups from baseline to day 7. Secondary outcomes included changes in sUA levels and 24-h uUA excretion. Results Both regimens lowered mean peak uUA excretion (least squares mean changes from baseline: −12.9 mg/h [95% confidence interval (CI): −21.0 to −4.7], dapagliflozin; −13.2 mg/h [95% CI −21.3 to –5.0], placebo). sUA concentrations were lower with dapagliflozin (mean treatment difference –62.3 µmol/L [95% CI −82.8 to −41.8]). Dapagliflozin did not impact verinurad pharmacokinetics, its main metabolites, or febuxostat or fasting plasma glucose levels vs verinurad plus febuxostat. There were no clinically relevant changes in safety parameters. Conclusions Dapagliflozin further reduced sUA without influencing uUA excretion, suggesting that its combination with verinurad and febuxostat at the doses tested does not adversely affect kidney function. Clinical trial registration number NCT03316131.

Objective To evaluate the 104-week safety of dapagliflozin in older patients with type 2 diabetes mellitus. Methods Pooled analysis assessing general safety (nine phase III studies ≤104 weeks) and cardiovascular safety (21 phase IIb/III studies ≤208 weeks) by age (<65; ≥65; ≥75 years). Patients with type 2 diabetes mellitus (±background glucose-lowering therapy) received: dapagliflozin 10 mg ( n  = 2026) vs. placebo ( n = 1956) (nine-study pool); or dapagliflozin (2.5–50 mg; n  = 5936) vs. control (placebo/comparator) ( n  = 3403) (21-study pool). Results Adverse events (AEs) and discontinuations owing to AEs were more common in older vs. younger patients, and were more frequent with dapagliflozin than placebo (AEs: <65 years: 73.1 vs. 70.7 %; ≥65 years: 77.4 vs. 73.1 %; ≥75 years: 80.4 vs. 75.3 %, respectively; discontinuations: <65 years: 5.9 vs. 5.0 %; ≥65 years: 14.4 vs. 12.2 %; ≥75 years: 26.8 vs. 22.1 %, respectively); serious AE (SAE) frequency was similar (<65 years: 11.0 vs. 11.8 %; ≥65 years: 20.0 vs. 20.2 %; ≥75 years: 19.6 vs. 18.2 %, respectively). Hypoglycaemia frequency was similar across age groups and was higher with dapagliflozin than placebo (<65 years: 18.0 vs. 13.4 %; ≥65 years: 20.2 vs. 17.7 %; ≥75 years: 17.5 vs. 16.9 %, respectively); major episodes were rare. Urinary tract infection frequency was similar between treatment groups in older patients, with no increase vs. younger patients (<65 years: 8.8 vs. 5.5 %; ≥65 years: 8.1 vs. 7.6 %; ≥75 years: 8.2 vs. 9.1 %, respectively); urinary tract infection SAEs were rare. Genital infection AEs were more common with dapagliflozin, with no increase in older patients (<65 years: 8.2 vs. 1.0 %; ≥65 years: 6.6 vs. 0.9 %; ≥75 years: 7.2 vs. 0.0 %, respectively) and no SAEs. Volume reduction AEs were uncommon, with a higher frequency with dapagliflozin vs. placebo and in patients ≥75 years (<65 years: 1.7 vs. 1.2 %; ≥65 years: 2.3 vs. 1.7 %; ≥75 years: 3.1 vs. 2.6 %, respectively). Dapagliflozin did not increase the risk of fractures (<65 years: 1.1 vs. 1.1 %; ≥65 years: 1.1 vs. 2.7 %; ≥75 years: 1.0 vs. 2.6 %, respectively) or falls (<65 years: 0.7 vs. 0.7 %; ≥65 years: 0.6 vs. 2.1 %; ≥75 years: 0.0 vs. 1.3 %, respectively), regardless of age. AEs of renal function were more common with dapagliflozin than placebo and increased with age (<65 years: 3.5 vs. 2.3 %; ≥65 years: 14.0 vs. 7.9 %; ≥75 years: 29.9 vs. 20.8 %, respectively). Most were non-serious small transient increases in serum creatinine. Dapagliflozin did not increase cardiovascular risk regardless of age [hazard ratio (95 % confidence interval) vs. control: <65 years: 0.726 (0.473, 1.114); ≥65 years: 0.879 (0.565, 1.366); ≥75 years: 0.950 (0.345, 2.617), respectively]. Conclusion Dapagliflozin treatment up to 104 weeks was well tolerated in older patients. Older dapagliflozin-treated patients had more renal AEs than placebo-treated patients; the majority of which were non-serious small transient changes in serum creatinine.

In a multicenter, randomized trial, 2776 patients undergoing maintenance hemodialysis who were not currently taking a statin were randomly assigned to rosuvastatin or placebo. At a median of 3.8 years of follow-up, rates of the composite primary end point of death from cardiovascular causes, myocardial infarction, or stroke did not differ significantly between the two study groups. Patients undergoing maintenance hemodialysis were randomly assigned to rosuvastatin or placebo. At a median of 3.8 years of follow-up, rates of the composite primary end point of death from cardiovascular causes, myocardial infarction, or stroke did not differ significantly between the two study groups. Patients undergoing maintenance hemodialysis have a greatly increased risk of premature cardiovascular disease. 1 , 2 However, the pattern of cardiovascular disease in such patients differs from that in the general population, and although the risk of myocardial infarction is increased, other cardiovascular events, such as sudden cardiac death and heart failure, predominate. 1 – 3 Moreover, the relationship between cardiovascular disease and conventional risk factors is inconsistent, inverse, or U-shaped. 1 , 2 , 4 Since low-density lipoprotein (LDL) cholesterol levels may be low or normal in patients with advanced renal disease, there is particular uncertainty regarding the use of lipid-lowering therapy. 1 , 2 , 4 , 5 Statin . . .
