Evidence summaries for obesity and weight management, including lifestyle trials, pharmacotherapy, bariatric/metabolic outcomes, cardiometabolic risk, and long-term safety.
A 26-week double-blind randomised trial testing once-weekly semaglutide added to automated insulin delivery in 72 adults with type 1 diabetes and obesity. PICO summary and expert commentary.
A first-in-human phase 1 trial of oral amycretin in overweight or obesity found it safe and tolerable, with dose-dependent gastrointestinal effects and exploratory weight loss. PICO summary and expert commentary.
Post hoc analysis of three randomised trials showing semaglutide produces similar weight loss in MASLD and MASH regardless of type 2 diabetes status or cardiometabolic risk. PICO summary and expert commentary.
A secondary analysis of a weight-loss-maintenance RCT found that low-calorie-diet weight loss raised serum 25(OH)D in both sexes, but further loss and low baseline vitamin D tracked with maintenance only in women. PICO summary and expert commentary.
A secondary patient-reported-outcomes analysis of the SURMOUNT-1 phase 3 trial finds tirzepatide improved health-related quality of life versus placebo in adults with obesity, with larger gains at greater weight loss. PICO summary and expert commentary.
An industry-sponsored indirect treatment comparison suggesting tirzepatide 10 and 15 mg achieve greater weight, BMI and HbA1c reduction than semaglutide 2.4 mg in type 2 diabetes, with no head-to-head trial. PICO summary and expert commentary.
A phase 1 first-in-human study of the oral GLP-1 receptor agonist ECC5004/AZD5004 in healthy volunteers and T2DM patients found it well tolerated with early dose-dependent glucose and weight signals. PICO summary and expert commentary.
An oral GLP-1 receptor agonist lowered HbA1c and body weight in phase 2 but was halted early after transaminase elevations ended its development. PICO summary and expert commentary.
A 253-adult randomized trial found that 25% calorie restriction produced consistent enteropancreatic hormone shifts across diet patterns, and that larger shifts were associated with more weight regain afterwards. PICO summary and expert commentary.
