Efficacy and safety of tirzepatide in children and adolescents with type 2 diabetes (SURPASS-PEDS): a randomised, double-blind, placebo-controlled, phase 3 trial.
Current treatment options for youth-onset type 2 diabetes are limited and have demonstrated lower glycaemic efficacy than those for adult-onset type 2 diabetes. We aimed to assess the safety and efficacy of tirzepatide, a glucose-dependent insulinotropic polypeptide and GLP-1 receptor agonist, compared with placebo in youth-onset type 2 diabetes. We conducted a phase 3, double-blind, placebo-controlled, multicentre (39 sites), multinational (eight countries) trial over 30 weeks, followed by an open-label extension for 22 weeks in which all participants received tirzepatide. Participants aged 10 to <18 years with youth-onset type 2 diabetes inadequately controlled with metformin and/or...

The effects on cardiovascular outcomes are uncertain. We conducted an active-comparator-controlled, double-blind, noninferiority trial in which patients with type 2 diabetes and atherosclerotic cardiovascular disease were randomly assigned in a 1:1 ratio to receive a weekly subcutaneous injection of tirzepatide (up to 15 mg) or dulaglutide (1.5 mg), an agent that has been shown to reduce the incidence of cardiovascular events. The primary end point was a composite of death from cardiovascular causes,...

Tirzepatide: A Systematic Update.
Tirzepatide is a new molecule capable of controlling glucose blood levels by combining the dual agonism of Glucose-Dependent Insulinotropic Polypeptide (GIP) and Glucagon-Like Peptide-1 (GLP-1) receptors. GIP and GLP1 are incretin hormones: they are released in the intestine in response to nutrient intake and stimulate pancreatic beta cell activity secreting insulin. GIP and GLP1 also have other metabolic functions. GLP1, in particular, reduces food intake and delays gastric emptying. Moreover, Tirzepatide has been shown to improve blood pressure and to reduce Low-Density Lipoprotein (LDL) cholesterol and triglycerides. Tirzepatide efficacy and safety were assessed in a phase III SURPASS...

Grade guide: A+/A is the strongest represented support; B+/B is substantial but qualified; C is limited, indirect, observational, or preclinical; D/E is weak, mechanistic-only, anecdotal, or insufficient.

Tirzepatide for overweight and obesity management.
Tirzepatide is a once-weekly dual agonist, acting on glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptors. It is approved at the same doses (5, 10 and 15 mg) for both type 2 diabetes (T2D) and chronic weight management. Following a search in PubMed, clinicaltrials.gov, conference abstracts and Lilly website, we review herein the global phase 3 SURMOUNT program on tirzepatide's safety and efficacy for chronic weight management. Additionally, we discuss findings from the regional SURMOUNT-CN and SURMOUNT-J trials (in East-Asian populations) and the phase 2 SYNERGY-NASH, phase 3 SURMOUNT-OSA and SUMMIT studies on tirzepatide's impact on...

Tirzepatide, a dual GIP/GLP-1 receptor co-agonist for the treatment of type 2 diabetes with unmatched effectiveness regrading glycaemic control and body weight reduction.
Tirzepatide is the first dual GIP/GLP-1 receptor co-agonist approved for the treatment of type 2 diabetes in the USA, Europe, and the UAE. Tirzepatide is an acylated peptide engineered to activate the GIP and GLP-1 receptors, key mediators of insulin secretion that are also expressed in regions of the brain that regulate food intake. Five clinical trials in type 2-diabetic subjects (SURPASS 1-5) have shown that tirzepatide at 5-15 mg per week reduces both HbA1c (1.24 to 2.58%) and body weight (5.4-11.7 kg) by amounts unprecedented for a single agent. A sizable proportion of patients (23.0 to 62.4%) reached an HbA1c of < 5.7% (which is the upper limit of the normal range indicating...
