Tirzepatide, a dual glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptor agonist, is a prospective therapy for type 2 diabetes mellitus (T2DM) [1-3].
Tizepatide(0.2 µM;7days) can ameliorate high glucose-induced neurodegeneration and overcome neuronal insulin resistance[4].
Tirzepatide (10 nmol/kg;14days; s.c) remarkably reduces LPS-mediated inflammatory responses by inhibiting the cardiac protein levels of TNF-α, IL-6, and IL-1B in mice[5]. Tirzepatide(3-10 nmol/kg;14days; s.c) enhances insulin sensitivity in obese mice[6]. Tirzepatide had anti-allergic inflammatory effects for the aeroallergen-induced model in obese asthma[7]. Tirzepatide improves beta-cell function and insulin sensitivity in type 2 diabetes[8].

Tirzepatide versus Semaglutide Once Weekly in Patients with Type 2 Diabetes
N Engl J Med 2021 Aug 5;385(6):503-515.PMID:34170647DOI:10.1056/NEJMoa2107519.
Background: Tirzepatide is a dual glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 (GLP-1) receptor agonist that is under development for the treatment of type 2 diabetes. The efficacy and safety of once-weekly Tirzepatide as compared with semaglutide, a selective GLP-1 receptor agonist, are unknown. Methods: In an open-label, 40-week, phase 3 trial, we randomly assigned 1879 patients, in a 1:1:1:1 ratio, to receive Tirzepatide at a dose of 5 mg, 10 mg, or 15 mg or semaglutide at a dose of 1 mg. At baseline, the mean glycated hemoglobin level was 8.28%, the mean age 56.6 years, and the mean weight 93.7 kg. The primary end point was the change in the glycated hemoglobin level from baseline to 40 weeks. Results: The estimated mean change from baseline in the glycated hemoglobin level was -2.01 percentage points, -2.24 percentage points, and -2.30 percentage points with 5 mg, 10 mg, and 15 mg of Tirzepatide, respectively, and -1.86 percentage points with semaglutide; the estimated differences between the 5-mg, 10-mg, and 15-mg Tirzepatide groups and the semaglutide group were -0.15 percentage points (95% confidence interval [CI], -0.28 to -0.03; P = 0.02), -0.39 percentage points (95% CI, -0.51 to -0.26; P<0.001), and -0.45 percentage points (95% CI, -0.57 to -0.32; P<0.001), respectively. Tirzepatide at all doses was noninferior and superior to semaglutide. Reductions in body weight were greater with Tirzepatide than with semaglutide (least-squares mean estimated treatment difference, -1.9 kg, -3.6 kg, and -5.5 kg, respectively; P<0.001 for all comparisons). The most common adverse events were gastrointestinal and were primarily mild to moderate in severity in the Tirzepatide and semaglutide groups (nausea, 17 to 22% and 18%; diarrhea, 13 to 16% and 12%; and vomiting, 6 to 10% and 8%, respectively). Of the patients who received Tirzepatide, hypoglycemia (blood glucose level, <54 mg per deciliter) was reported in 0.6% (5-mg group), 0.2% (10-mg group), and 1.7% (15-mg group); hypoglycemia was reported in 0.4% of those who received semaglutide. Serious adverse events were reported in 5 to 7% of the patients who received Tirzepatide and in 3% of those who received semaglutide. Conclusions: In patients with type 2 diabetes, Tirzepatide was noninferior and superior to semaglutide with respect to the mean change in the glycated hemoglobin level from baseline to 40 weeks.

Tirzepatide Once Weekly for the Treatment of Obesity
N Engl J Med 2022 Jul 21;387(3):205-216.PMID:35658024DOI:10.1056/NEJMoa2206038.
Background: Obesity is a chronic disease that results in substantial global morbidity and mortality. The efficacy and safety of Tirzepatide, a novel glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptor agonist, in people with obesity are not known. Methods: In this phase 3 double-blind, randomized, controlled trial, we assigned 2539 adults with a body-mass index (BMI; the weight in kilograms divided by the square of the height in meters) of 30 or more, or 27 or more and at least one weight-related complication, excluding diabetes, in a 1:1:1:1 ratio to receive once-weekly, subcutaneous Tirzepatide (5 mg, 10 mg, or 15 mg) or placebo for 72 weeks, including a 20-week dose-escalation period. Coprimary end points were the percentage change in weight from baseline and a weight reduction of 5% or more. The treatment-regimen estimand assessed effects regardless of treatment discontinuation in the intention-to-treat population. Results: At baseline, the mean body weight was 104.8 kg, the mean BMI was 38.0, and 94.5% of participants had a BMI of 30 or higher. The mean percentage change in weight at week 72 was -15.0% (95% confidence interval [CI], -15.9 to -14.2) with 5-mg weekly doses of Tirzepatide, -19.5% (95% CI, -20.4 to -18.5) with 10-mg doses, and -20.9% (95% CI, -21.8 to -19.9) with 15-mg doses and -3.1% (95% CI, -4.3 to -1.9) with placebo (P<0.001 for all comparisons with placebo). The percentage of participants who had weight reduction of 5% or more was 85% (95% CI, 82 to 89), 89% (95% CI, 86 to 92), and 91% (95% CI, 88 to 94) with 5 mg, 10 mg, and 15 mg of Tirzepatide, respectively, and 35% (95% CI, 30 to 39) with placebo; 50% (95% CI, 46 to 54) and 57% (95% CI, 53 to 61) of participants in the 10-mg and 15-mg groups had a reduction in body weight of 20% or more, as compared with 3% (95% CI, 1 to 5) in the placebo group (P<0.001 for all comparisons with placebo). Improvements in all prespecified cardiometabolic measures were observed with Tirzepatide. The most common adverse events with Tirzepatide were gastrointestinal, and most were mild to moderate in severity, occurring primarily during dose escalation. Adverse events caused treatment discontinuation in 4.3%, 7.1%, 6.2%, and 2.6% of participants receiving 5-mg, 10-mg, and 15-mg Tirzepatide doses and placebo, respectively. Conclusions: In this 72-week trial in participants with obesity, 5 mg, 10 mg, or 15 mg of Tirzepatide once weekly provided substantial and sustained reductions in body weight.

Tirzepatide: First Approval
Drugs 2022 Jul;82(11):1213-1220.PMID:35830001DOI:10.1007/s40265-022-01746-8.
Tirzepatide (Mounjaro™) is a single molecule that combines dual agonism of glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. Native GIP and GLP-1 are incretin hormones that stimulate insulin secretion and decrease glucagon secretion. GIP also plays a role in nutrient and energy metabolism, while GLP-1 also delays gastric emptying, supresses appetite and improves satiety. Eli Lilly is developing Tirzepatide for the treatment of type 2 diabetes mellitus (T2DM), obesity, cardiovascular disorders in T2DM, heart failure, non-alcoholic steatohepatitis, obstructive sleep apnoea and for reducing mortality/morbidity in obesity. In May 2022, Tirzepatide received its first approval in the USA to improve glycaemic control in adults with T2DM, as an adjunct to diet and exercise. Tirzepatide is in phase III development for heart failure, obesity and cardiovascular disorders in T2DM, and in phase II development for non-alcoholic steatohepatitis. This article summarizes the milestones in the development of Tirzepatide leading to this first approval for T2DM.
Dual GIP and GLP-1 Receptor Agonist Tirzepatide Improves Beta-cell Function and Insulin Sensitivity in Type 2 Diabetes
J Clin Endocrinol Metab 2021 Jan 23;106(2):388-396.PMID:33236115DOI:10.1210/clinem/dgaa863.
Context: Novel dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist (RA) Tirzepatide demonstrated substantially greater glucose control and weight loss (WL) compared with selective GLP-1RA dulaglutide. Objective: Explore mechanisms of glucose control by Tirzepatide. Design: Post hoc analyses of fasting biomarkers and multiple linear regression analysis. Setting: Forty-seven sites in 4 countries. Patients or other participants: Three hundred and sixteen subjects with type 2 diabetes. Interventions: Tirzepatide (1, 5, 10, 15 mg), dulaglutide (1.5 mg), placebo. Main outcome measures: Analyze biomarkers of beta-cell function and insulin resistance (IR) and evaluate WL contributions to IR improvements at 26 weeks. Results: Homeostatic model assessment (HOMA) 2-B significantly increased with dulaglutide and Tirzepatide 5, 10, and 15 mg compared with placebo (P ≤ .02). Proinsulin/insulin and proinsulin/C-peptide ratios significantly decreased with Tirzepatide 10 and 15 mg compared with placebo and dulaglutide (P ≤ .007). Tirzepatide 10 and 15 mg significantly decreased fasting insulin (P ≤ .033) and Tirzepatide 10 mg significantly decreased HOMA2-IR (P = .004) compared with placebo and dulaglutide. Markers of improved insulin sensitivity (IS) adiponectin, IGFBP-1, and IGFBP-2 significantly increased by 1 or more doses of Tirzepatide (P < .05). To determine whether improvements in IR were directly attributable to WL, multiple linear regression analysis with potential confounding variables age, sex, metformin, triglycerides, and glycated hemoglobin A1c was conducted. WL significantly (P ≤ .028) explained only 13% and 21% of improvement in HOMA2-IR with Tirzepatide 10 and 15 mg, respectively. Conclusions: Tirzepatide improved markers of IS and beta-cell function to a greater extent than dulaglutide. IS effects of Tirzepatide were only partly attributable to WL, suggesting dual receptor agonism confers distinct mechanisms of glycemic control.
The Role of Tirzepatide, Dual GIP and GLP-1 Receptor Agonist, in the Management of Type 2 Diabetes: The SURPASS Clinical Trials
Diabetes Ther 2021 Jan;12(1):143-157.PMID:33325008DOI:10.1007/s13300-020-00981-0.
Glucagon-like peptide 1 (GLP-1) based therapy is an established treatment option for the management of type 2 diabetes mellitus (T2DM) and is recommended early in the treatment algorithm owing to glycaemic efficacy, weight reduction and favourable cardiovascular outcomes. Glucose-dependent insulinotropic polypeptide (GIP), on the other hand, was thought to have no potential as a glucose-lowering therapy because of observations showing no insulinotropic effect from supraphysiological infusion in people with T2DM. However, emerging evidence has illustrated that co-infusion of GLP-1 and GIP has a synergetic effect, resulting in significantly increased insulin response and glucagonostatic response, compared with separate administration of each hormone. These observations have led to the development of a dual GIP/GLP-1 receptor agonist, known as a 'twincretin'. Tirzepatide is a novel dual GIP/GLP-1 receptor agonist formulated as a synthetic peptide containing 39 amino acids, based on the native GIP sequence. Pre-clinical trials and phase 1 and 2 clinical trials indicate that Tirzepatide has potent glucose lowering and weight loss with adverse effects comparable to those of established GLP-1 receptor agonists. The long-term efficacy, safety and cardiovascular outcomes of Tirzepatide will be investigated in the SURPASS phase 3 clinical trial programme. In this paper, we will review the pre-clinical and phase 1 and 2 trials for Tirzepatide in the management of T2DM and give an overview of the SURPASS clinical trials.
