Tirzepatide Phase 1 Trial
A phase 1 clamp trial shows tirzepatide improves beta-cell function and insulin sensitivity more than semaglutide, explaining its glucose-lowering. PICO summary and commentary.
Clinical trial summaries for GLP-1 receptor agonists, including cardiovascular outcomes, glycaemic control, obesity, kidney outcomes, tolerability, and practice implications.
A phase 1 clamp trial shows tirzepatide improves beta-cell function and insulin sensitivity more than semaglutide, explaining its glucose-lowering. PICO summary and commentary.
In patients with heart failure with preserved ejection fraction (HFpEF) and obesity, tirzepatide significantly reduced the composite risk of cardiovascular death or worsening heart failure and improved health status compared to placebo, though it was associated with higher gastrointestinal side effects.
In children aged 6 to
In adults with moderate-to-severe obstructive sleep apnoea (OSA) and obesity, tirzepatide significantly reduced the apnea-hypopnea index (AHI) and body weight compared to placebo, with notable improvements in sleep-related outcomes and cardiovascular risk factors, albeit with increased gastrointestinal side effects.
In patients with obesity and knee osteoarthritis, once-weekly semaglutide (2.4 mg) significantly reduced body weight and pain compared to placebo, though it was associated with gastrointestinal side effects.
In adults with type 2 diabetes inadequately controlled with metformin (alone or with sulfonylurea), oral semaglutide (7 mg and 14 mg) significantly reduced HbA1c and body weight compared to sitagliptin over 26 weeks, while the 3 mg dose showed no significant benefit.
In patients with inadequately controlled type 2 diabetes on SGLT-2 inhibitors, adding semaglutide significantly improved HbA1c and reduced body weight compared to placebo, though it was associated with an increased frequency of gastrointestinal side effects.
