Semaglutide Effects on Cardiovascular Outcomes in People With Overweight or Obesity (SELECT) rationale and design
Cardiovascular disease (CVD) is a major cause of morbidity and mortality. Although it has been widely appreciated that obesity is a major risk factor for CVD, treatments that produce effective, durable weight loss and the impact of weight reduction in reducing cardiovascular risk have been elusive. Instead, progress in CVD risk reduction has been achieved through medications indicated for controlling lipids, hyperglycemia, blood pressure, heart failure, inflammation, and/or thrombosis. Obesity has been implicated as promoting all these issues, suggesting that sustained, effective weight loss may have independent cardiovascular benefit. GLP-1 receptor agonists (RAs) reduce weight, improve glycemia, decrease cardiovascular events in those with diabetes, and may have additional cardioprotective effects. The GLP-1 RA semaglutide is in phase 3 studies as a medication for obesity treatment at a dose of 2.4 mg subcutaneously (s.c.) once weekly. Semaglutide Effects on Heart Disease and Stroke in Patients with Overweight or Obesity (SELECT) is a randomized, double-blind, parallel-group trial testing if semaglutide 2.4 mg subcutaneously once weekly is superior to placebo when added to standard of care for preventing major adverse cardiovascular events in patients with established CVD and overweight or obesity but without diabetes. SELECT is the first cardiovascular outcomes trial to evaluate superiority in major adverse cardiovascular events reduction for an antiobesity medication in such a population. As such, SELECT has the potential for advancing new approaches to CVD risk reduction while targeting obesity.

Gestational weight gain across continents and ethnicity: systematic review and meta-analysis of maternal and infant outcomes in more than one million women
Background
The association between Institute of Medicine (IOM) guidelines and pregnancy outcomes across ethnicities is uncertain. We evaluated the associations of gestational weight gain (GWG) outside 2009 IOM guidelines, with maternal and infant outcomes across the USA, western Europe and east Asia, with subgroup analyses in Asia. The aim was to explore ethnic differences in maternal prepregnancy body mass index (BMI), GWG and health outcomes across these regions.
Methods
Systematic review, meta-analysis and meta-regression of observational studies were used for the study. MEDLINE, MEDLINE In-Process, Embase and all Evidence-Based Medicine (EBM) Reviews were searched from 1999 to 2017. Studies were stratified by prepregnancy BMI category and total pregnancy GWG. Odds ratio (ORs) 95% confidence intervals (CI) applied recommended GWG within each BMI category as the reference. Primary outcomes were small for gestational age (SGA), preterm birth and large for gestational age (LGA). Secondary outcomes were macrosomia, caesarean section and gestational diabetes.
Results
Overall, 5874 studies were identified and 23 were included (
n
= 1,309,136). Prepregnancy overweight/obesity in the USA, Europe and Asia was measured at 42%, 30% and 10% respectively, with underweight 5%, 3% and 17%. GWG below guidelines in the USA, Europe and Asia was 21%, 18% and 31%, and above was 51%, 51% and 37% respectively. Applying regional BMI categories in Asia showed GWG above guidelines (51%) was similar to that in the USA and Europe.
GWG below guidelines was associated with a higher risk of SGA (USA/Europe [OR 1.51; CI 1.39, 1.63]; Asia [1.63; 1.45, 1.82]) and preterm birth (USA/Europe [1.35; 1.17, 1.56]; Asia [1.06; 0.78, 1.44]) than GWG within guidelines. GWG above guidelines was associated with a higher risk of LGA (USA/Europe [1.93; 1.81, 2.06]; Asia [1.68; 1.51 , 1.87]), macrosomia (USA/Europe [1.87; 1.70, 2.06]; Asia [2.18; 1.91, 2.49]) and caesarean (USA/Europe [1.26; 1.21, 1.33]; Asia [1.37; 1.30, 1.45]). Risks remained elevated when regional BMI categories were applied for GWG recommendations. More women in Asia were categorised as having GWG below guidelines using World Health Organization (WHO) (60%) compared to regional BMI categories (16%), yet WHO BMI was not accompanied by increased risks of adverse outcomes.
Conclusions
Women in the USA and western Europe have higher prepregnancy BMI and higher rates of GWG above guidelines than women in east Asia. However, when using regional BMI categories in east Asia, rates of GWG above guidelines are similar across the three continents. GWG outside guidelines is associated with adverse outcomes across all regions. If regional BMI categories are used in east Asia, IOM guidelines are applicable in the USA, western Europe and east Asia.

Doctor Referral of Overweight People to Low Energy total diet replacement Treatment (DROPLET): pragmatic randomised controlled trial
AbstractObjectiveTo test the effectiveness and safety of a total diet replacement (TDR) programme for routine treatment of obesity in a primary care setting.DesignPragmatic, two arm, parallel group, open label, individually randomised controlled trial.Setting10 primary care practices in Oxfordshire, UK.Participants278 adults who were obese and seeking support to lose weight: 138 were assigned to the TDR programme and 140 to usual care. 73% of participants were re-measured at 12 months.InterventionsThe TDR programme comprised weekly behavioural support for 12 weeks and monthly support for three months, with formula food products providing 810 kcal/day (3389 kJ/day) as the sole food during the first eight weeks followed by reintroduction of food. Usual care comprised behavioural support for weight loss from a practice nurse and a diet programme with modest energy restriction.Main outcome measuresThe primary outcome was weight change at 12 months analysed as intention to treat with mixed effects models. Secondary outcomes included biomarkers of cardiovascular and metabolic risk. Adverse events were recorded.ResultsParticipants in the TDR group lost more weight (−10.7 kg) than those in the usual care group (−3.1 kg): adjusted mean difference −7.2 kg (95% confidence interval −9.4 to −4.9 kg). 45% of participants in the TDR group and 15% in the usual care group experienced weight losses of 10% or more. The TDR group showed greater improvements in biomarkers of cardiovascular and metabolic risk than the usual care group. 11% of participants in the TDR group and 12% in the usual care group experienced adverse events of moderate or greater severity.ConclusionsCompared with regular weight loss support from a practice nurse, a programme of weekly behavioural support and total diet replacement providing 810 kcal/day seems to be tolerable, and leads to substantially greater weight loss and greater improvements in the risk of cardiometabolic disease.Trial registrationInternational Standard Randomised Controlled Trials No ISRCTN75092026.

Cagrilintide–Semaglutide in Adults with Overweight or Obesity and Type 2 Diabetes
Cagrilintide and semaglutide have each been shown to induce weight loss as monotherapies. Data are needed on the coadministration of cagrilintide and semaglutide (called CagriSema) for weight management in adults with type 2 diabetes, including those in a subgroup who are undergoing continuous glucose monitoring.
In this phase 3a, double-blind, randomized, placebo-controlled trial conducted in 12 countries, we assigned adults with a body-mass index of 27 or more, a glycated hemoglobin level of 7 to 10%, and type 2 diabetes in a 3:1 ratio to receive once-weekly cagrilintide-semaglutide (2.4 mg each) or placebo, along with lifestyle intervention, for 68 weeks. The two primary end points were the percent change in body weight and the percentage of patients with a weight reduction of at least 5%. Additional end points were changes in glycemic measures and safety assessments. Effect estimates were calculated with the use of the treatment-policy estimand (consistent with the intention-to-treat principle).
A total of 1206 patients underwent randomization to either the cagrilintide-semaglutide group (904 patients) or the placebo group (302 patients). The estimated mean change in body weight from baseline to week 68 was -13.7% in the cagrilintide-semaglutide group and -3.4% in the placebo group (estimated difference, -10.4 percentage points; 95% confidence interval, -11.2 to -9.5; P<0.001). More patients in the cagrilintide-semaglutide group than in the placebo group had a weight reduction of 5% or more (P<0.001); the same was true of reductions of at least 10%, 15%, and 20% (P<0.001 for the last comparison). The percentage of patients who had a glycated hemoglobin level of 6.5% or less was 73.5% in the cagrilintide-semaglutide group and 15.9% in the placebo group. Gastrointestinal adverse events were reported by 72.5% of the patients in the cagrilintide-semaglutide group and 34.4% in the placebo group, most of which were transient and mild or moderate in severity.
Once-weekly cagrilintide-semaglutide (at a dose of 2.4 mg each) resulted in a significantly lower body weight than placebo in adults with obesity and type 2 diabetes. (Funded by Novo Nordisk; REDEFINE 2 ClinicalTrials.gov number, NCT05394519.).
