Adults aged 50–64 years have a high incidence of symptomatic influenza associated with substantial disease and economic burden each year. We conducted a randomized, controlled trial to compare the immunogenicity and safety of an adjuvanted quadrivalent inactivated influenza vaccine (aIIV4; n = 1027) with a nonadjuvanted standard dose IIV4 (n = 1017) in this population. Immunogenicity was evaluated on Days 22, 181, and 271. On Day 22, upper limits (UL) of 95% confidence intervals (CI) for geometric mean titer (GMT) ratios (IIV4/aIIV4) were <1.5 and 95% CI ULs for the difference in seroconversion rate (SCR IIV4 − aIIV4) were <10% for all four vaccine strains, meeting primary endpoint noninferiority criteria. Protocol-defined superiority criteria (95% CI ULs < 1.0) were also met for A(H1N1) and A(H3N2). Immune responses following aIIV4 vaccination were more pronounced in persons with medical comorbidities and those not recently vaccinated against influenza. Safety data were consistent with previous studies of MF59 adjuvanted seasonal and pandemic influenza vaccines. These findings support the immunological benefit of aIIV4 for persons aged 50–64 years, especially those with comorbidities.

Glucagon-like peptide 1 receptor agonists differ in chemical structure, duration of action, and in their effects on clinical outcomes. The cardiovascular effects of once-weekly albiglutide in type 2 diabetes are unknown. We aimed to determine the safety and efficacy of albiglutide in preventing cardiovascular death, myocardial infarction, or stroke. We did a double-blind, randomised, placebo-controlled trial in 610 sites across 28 countries. We randomly assigned patients aged 40 years and older with type 2 diabetes and cardiovascular disease (at a 1:1 ratio) to groups that either received a subcutaneous injection of albiglutide (30–50 mg, based on glycaemic response and tolerability) or of a matched volume of placebo once a week, in addition to their standard care. Investigators used an interactive voice or web response system to obtain treatment assignment, and patients and all study investigators were masked to their treatment allocation. We hypothesised that albiglutide would be non-inferior to placebo for the primary outcome of the first occurrence of cardiovascular death, myocardial infarction, or stroke, which was assessed in the intention-to-treat population. If non-inferiority was confirmed by an upper limit of the 95% CI for a hazard ratio of less than 1·30, closed testing for superiority was prespecified. This study is registered with ClinicalTrials.gov, number NCT02465515. Patients were screened between July 1, 2015, and Nov 24, 2016. 10 793 patients were screened and 9463 participants were enrolled and randomly assigned to groups: 4731 patients were assigned to receive albiglutide and 4732 patients to receive placebo. On Nov 8, 2017, it was determined that 611 primary endpoints and a median follow-up of at least 1·5 years had accrued, and participants returned for a final visit and discontinuation from study treatment; the last patient visit was on March 12, 2018. These 9463 patients, the intention-to-treat population, were evaluated for a median duration of 1·6 years and were assessed for the primary outcome. The primary composite outcome occurred in 338 (7%) of 4731 patients at an incidence rate of 4·6 events per 100 person-years in the albiglutide group and in 428 (9%) of 4732 patients at an incidence rate of 5·9 events per 100 person-years in the placebo group (hazard ratio 0·78, 95% CI 0·68–0·90), which indicated that albiglutide was superior to placebo (p<0·0001 for non-inferiority; p=0·0006 for superiority). The incidence of acute pancreatitis (ten patients in the albiglutide group and seven patients in the placebo group), pancreatic cancer (six patients in the albiglutide group and five patients in the placebo group), medullary thyroid carcinoma (zero patients in both groups), and other serious adverse events did not differ between the two groups. There were three (<1%) deaths in the placebo group that were assessed by investigators, who were masked to study drug assignment, to be treatment-related and two (<1%) deaths in the albiglutide group. In patients with type 2 diabetes and cardiovascular disease, albiglutide was superior to placebo with respect to major adverse cardiovascular events. Evidence-based glucagon-like peptide 1 receptor agonists should therefore be considered as part of a comprehensive strategy to reduce the risk of cardiovascular events in patients with type 2 diabetes.

Semaglutide, a GLP-1 receptor agonist, reduces the risk of major adverse cardiovascular events (MACE) in people with overweight or obesity, but the effects of this drug on outcomes in patients with atherosclerotic cardiovascular disease and heart failure are unknown. We report a prespecified analysis of the effect of once-weekly subcutaneous semaglutide 2·4 mg on ischaemic and heart failure cardiovascular outcomes. We aimed to investigate if semaglutide was beneficial in patients with atherosclerotic cardiovascular disease with a history of heart failure compared with placebo; if there was a difference in outcome in patients designated as having heart failure with preserved ejection fraction compared with heart failure with reduced ejection fraction; and if the efficacy and safety of semaglutide in patients with heart failure was related to baseline characteristics or subtype of heart failure. The SELECT trial was a randomised, double-blind, multicentre, placebo-controlled, event-driven phase 3 trial in 41 countries. Adults aged 45 years and older, with a BMI of 27 kg/m2 or greater and established cardiovascular disease were eligible for the study. Patients were randomly assigned (1:1) with a block size of four using an interactive web response system in a double-blind manner to escalating doses of once-weekly subcutaneous semaglutide over 16 weeks to a target dose of 2·4 mg, or placebo. In a prespecified analysis, we examined the effect of semaglutide compared with placebo in patients with and without a history of heart failure at enrolment, subclassified as heart failure with preserved ejection fraction, heart failure with reduced ejection fraction, or unclassified heart failure. Endpoints comprised MACE (a composite of non-fatal myocardial infarction, non-fatal stroke, and cardiovascular death); a composite heart failure outcome (cardiovascular death or hospitalisation or urgent hospital visit for heart failure); cardiovascular death; and all-cause death. The study is registered with ClinicalTrials.gov, NCT03574597. Between Oct 31, 2018, and March 31, 2021, 17 604 patients with a mean age of 61·6 years (SD 8·9) and a mean BMI of 33·4 kg/m2 (5·0) were randomly assigned to receive semaglutide (8803 [50·0%] patients) or placebo (8801 [50·0%] patients). 4286 (24·3%) of 17 604 patients had a history of investigator-defined heart failure at enrolment: 2273 (53·0%) of 4286 patients had heart failure with preserved ejection fraction, 1347 (31·4%) had heart failure with reduced ejection fraction, and 666 (15·5%) had unclassified heart failure. Baseline characteristics were similar between patients with and without heart failure. Patients with heart failure had a higher incidence of clinical events. Semaglutide improved all outcome measures in patients with heart failure at random assignment compared with those without heart failure (hazard ratio [HR] 0·72, 95% CI 0·60–0·87 for MACE; 0·79, 0·64–0·98 for the heart failure composite endpoint; 0·76, 0·59–0·97 for cardiovascular death; and 0·81, 0·66–1·00 for all-cause death; all pinteraction>0·19). Treatment with semaglutide resulted in improved outcomes in both the heart failure with reduced ejection fraction (HR 0·65, 95% CI 0·49–0·87 for MACE; 0·79, 0·58–1·08 for the composite heart failure endpoint) and heart failure with preserved ejection fraction groups (0·69, 0·51–0·91 for MACE; 0·75, 0·52–1·07 for the composite heart failure endpoint), although patients with heart failure with reduced ejection fraction had higher absolute event rates than those with heart failure with preserved ejection fraction. For MACE and the heart failure composite, there were no significant differences in benefits across baseline age, sex, BMI, New York Heart Association status, and diuretic use. Serious adverse events were less frequent with semaglutide versus placebo, regardless of heart failure subtype. In patients with atherosclerotic cardiovascular diease and overweight or obesity, treatment with semaglutide 2·4 mg reduced MACE and composite heart failure endpoints compared with placebo in those with and without clinical heart failure, regardless of heart failure subtype. Our findings could facilitate prescribing and result in improved clinical outcomes for this patient group. Novo Nordisk.

Obstructive sleep apnoea (OSA) is highly prevalent but approved pharmacological treatment options are missing. Sultiame improves the ventilatory response and upper airway muscle activity by inhibiting carbonic anhydrase. This study aimed to prospectively assess the efficacy and safety of three dosages of sultiame in OSA. This multicentre, randomised, parallel, double-blind, placebo-controlled, dose-finding, phase 2 trial was performed at 28 hospitals and community-based sites in five European countries. Adults (aged 18–75 years) with untreated, moderate to severe OSA and an Apnoea–Hypopnea Index (AHI) of ≥15 to ≤50 events per h were randomly assigned (1:1:1:1), using interactive response technology, to receive placebo or sultiame 100 mg, 200 mg, or 300 mg tablets of identical appearance once per day at bedtime for 15 weeks. Randomisation was stratified by baseline AHI3a. The primary outcome measure for efficacy was the relative change of AHI3a from baseline to week 15 (scheduled treatment end). All participants who were randomly assigned were included in the primary efficacy analysis using an estimands framework and in the safety analysis. This trial is registered with EudraCT (2021–002926–26) and ClinicalTrials.gov (NCT05236842) and is complete. Between Dec 2, 2021, and April 8, 2023, 535 patients were screened and 298 were randomly assigned to placebo (n=75), or sultiame 100 mg (n=74), 200 mg (n=74), or 300 mg (n=75). 240 patients completed 15 weeks of treatment. 220 (74%) of 298 participants were male and 78 (26%) were female. In the full analysis set, placebo-subtracted relative AHI3a adjusted means change at week 15 was –16·4% (95% CI –31·3 to –1·4; p=0·032), –30·2% (–45·4 to –15·1; p<0·0001), and 34·6% (–49·1 to –20·0; p<0·0001) for sultiame 100 mg, 200 mg, and 300 mg, respectively. The incidence of adverse events increased dose-dependently: 46 (61%) of 75 patients in the placebo group, 54 (73%) of 74 in the 100 mg group, 62 (84%) of 74 in the 200 mg group, and 68 (91%) of 75 in the 300 mg group. Events reported in more than 10% of patients in the placebo, 100 mg, 200 mg, or 300 mg groups were paraesthesia (seven [9%] of 75, 16 [22%] of 74, 32 [43%] of 74, 43 [57%] of 75), headache (six [8%], five [7%], 12 [16%], 11 [15%]), COVID-19 (three [4%], three [4%], six [8%], ten [13%]), and nasopharyngitis (nine [12%], three [4%], seven [9%], seven [9%]). Sultiame caused consistent, dose-dependent improvements of OSA, nocturnal hypoxia, sleep quality, and excessive daytime sleepiness. These findings offer perspectives for a pharmaceutical approach to treatment of patients with obstructive sleep apnoea. Desitin Arzneimittel.

Collagenous colitis is an idiopathic microscopic colitis characterised by watery diarrhoea. The impact of collagenous colitis on quality of life has not been assessed. Our aim was to assess quality of life in patients with this condition and compare the effect of treatment with budesonide capsules or placebo on this parameter. Patients with chronic diarrhoea and histologically-proven collagenous colitis were randomised to receive either budesonide controlled-release capsules (Entocort capsules, AstraZeneca, Lund, Sweden), 9 mg/day, or placebo for 6 weeks. Quality of life was measured using the validated Gastrointestinal Quality of Life Index (GIQLI) at baseline and after 6 weeks. With the GIQLI, scores range from 0 to 144, with higher scores representing better quality of life. Complete quality of life assessment was available in 29 patients (budesonide: n=17; placebo: n=12). At baseline, quality of life was low in patients with collagenous colitis (mean 76). After 6 weeks of treatment, the mean GIQLI score increased significantly in the budesonide group (from 67 to 92, p<0.001), but remained unchanged in the placebo group (86-88). The mean score of the dimensions symptoms (p=0.001), emotional functioning (p=0.003) and physical functioning (p=0.017) increased significantly in the budesonide group compared with the placebo group. A significantly larger proportion of patients in the budesonide group experienced improved stool consistency (p<0.01) and a significant reduction in the mean stool frequency compared with those in the placebo group (p<0.01). Quality of life is seriously reduced in patients with collagenous colitis. Six-week treatment with oral budesonide controlled-release capsules significantly improves quality of life and clinical symptoms compared with placebo in these patients.

Background Childhood cancer survivors are at risk of subsequent gliomas and meningiomas, but the risks beyond age 40 years are uncertain. We quantified these risks in the largest ever cohort. Methods Using data from 69,460 5-year childhood cancer survivors (diagnosed 1940–2008), across Europe, standardized incidence ratios (SIRs) and cumulative incidence were calculated. Results In total, 279 glioma and 761 meningioma were identified. CNS tumour (SIR: 16.2, 95% CI: 13.7, 19.2) and leukaemia (SIR: 11.2, 95% CI: 8.8, 14.2) survivors were at greatest risk of glioma. The SIR for CNS tumour survivors was still 4.3-fold after age 50 (95% CI: 1.9, 9.6), and for leukaemia survivors still 10.2-fold after age 40 (95% CI: 4.9, 21.4). Following cranial radiotherapy (CRT), the cumulative incidence of a glioma in CNS tumour survivors was 2.7%, 3.7% and 5.0% by ages 40, 50 and 60, respectively, whilst for leukaemia this was 1.2% and 1.7% by ages 40 and 50. The cumulative incidence of a meningioma after CRT in CNS tumour survivors doubled from 5.9% to 12.5% between ages 40 and 60, and in leukaemia survivors increased from 5.8% to 10.2% between ages 40 and 50. Discussion Clinicians following up survivors should be aware that the substantial risks of meningioma and glioma following CRT are sustained beyond age 40 and be vigilant for symptoms.
