Tirzepatide Treatment Options in California

The purpose of this study is to conduct a three-arm 52-week, randomized controlled trial with double blind treatment to evaluate the effects of a drug called tirzepatide in combination with an innovative, culturally-appropriate, intensive lifestyle intervention (ILI) delivered by community health workers (CHWs) in Latino adults with obesity. Participants will be randomized to 1) standard care (SC, n=25); 2) culturally-tailored dietary and behavioral intensive lifestyle intervention (ILI, n=25) provided by CHWs plus placebo; or 3) ILI plus tirzepatide (ILI-TRZ) for 52 weeks to evaluate the intervention's effect on: i) weight loss; ii) clinical efficacy (change in body fat mass, liver fat, intra-abdominal fat mass and intrahepatic triglyceride content, oral glucose tolerance, glycemic control, insulin sensitivity and b-cell function, plasma lipids, blood pressure, sleep duration, quality and behaviors, physical performance scores); iii) adherence and fidelity to the intervention (adherence to the intervention and barriers to long term adherence, quality-of-life, fidelity of the implementation by CHWs, CHW's and study participants' acceptability and satisfaction with the intervention and eating behaviors. Placebo or tirzepatide will be injected subcutaneously in the abdomen or thigh once a week for 12 months. Read Less

This is a Phase 2 study to evaluate the safety and efficacy of 24, 36, and 48 mg GZR18 (Q2W) compared with placebo and 15 mg tirzepatide (QW). The study will evaluate weight management in participants with obesity (BMI ≥30 kg/m2) or who are overweight (BMI ≥27 kg/m2) with weight-related comorbidities (excluding type 2 diabetes mellitus).

The purpose of this study is to see if the study drug, tirzepatide administered once weekly, is safe and effective as a treatment for Nonalcoholic Steatohepatitis (NASH). Read Less

A phase 2 study to assess the efficacy of NA-931 alone or in addition to Tirzepatide to assess efficacy and safety in overweight or obese men and women Read Less

The main purpose of this study is to investigate the effects of switching from glucagon-like peptide-1 receptor agonist (GLP-1 RA) therapy to tirzepatide glucose-dependent insulinotropic polypeptide (GIP) GLP-1 RA agonist in participants with type 2 diabetes (T2D). Read Less

The main purpose of this phase 3b study is to evaluate the efficacy and safety of tirzepatide compared with semaglutide in adult participants who have obesity or overweight with weight related comorbidities without Type 2 Diabetes. The study will last around 74 weeks. Read Less

Obesity, affecting 40% of US adults and costing 173b annually, represents a significant health care burden (1). It is associated with increased risk for multiple chronic diseases including hypertension, type 2 diabetes (T2D), cardiovascular disease, and NAFLD, as well as cancer, osteoarthritis, and obstructive sleep apnea. The investigators plan to test the hypothesis that tirzepatide, a dual GLP/GIP agonist, improves metabolic health (insulin resistance and regional fat distribution and cardiovascular risk profile) not only by inducing weight loss via GLP1-agonism, but also via beneficial cellular and molecular changes in adipose tissue, given that GIP binds receptors in human fat cells. Based on studies in mice showing that GIP alone or tirzepitide treatment decreases inflammation, increases lipid buffering (fat storage in the fat cells instead of releasing it into the bloodstream), and improves glucose homeostasis. The investigators believe that the GIP component of tirzepatide will make fat cells healthier and reverse lipotoxicity, which is one of the mechanisms by which obesity leads to insulin resistance, disordered regional fat distribution, and type 2 diabetes. To date, the effect of dual GLP1 and GIP agonist treatment on adipose tissue has not been evaluated in humans. Given the existing but limited data, dual GIP/GLP-1 agonist treatment in obese humans with metabolic risk factors is an attractive pharmacologic candidate that would lead to both weight loss and healthier fat, potentially offering uniquely powerful synergistic clinical benefits. It is thus of tremendous importance to define the biological effects of dual-agonist treatment on human adipose tissue structure and function, as well as related improvements in regional fat distribution and systemic adipose and muscle insulin sensitivity. In this study, the investigators will randomize overweight (with risk factors) or obese nondiabetic individuals to hypocaloric diet or tirzepatide for 22 weeks with matched weight loss for the first 6 weeks. The investigators will quantify insulin resistance, fat and lean mass, including regional fat distribution, and changes in adipose tissue (needle biopsy from abdominal fat tissue) to see if tirzepatide effects differ from dietary weight loss.

This study is to investigate how adipocyte (fat cell) function and fat distribution differ between individuals with normal-weight type 2 diabetes (NWD) and normal-weight controls without diabetes (NWC). The study will assess whether adipocyte-directed therapies, specifically pioglitazone and tirzepatide, can improve insulin resistance, adipocyte function, and fat distribution in individuals with NWD. By analyzing the biological mechanisms underlying adipocyte dysfunction, the study aims to provide insights into novel treatment strategies for improving metabolic health in normal-weight individuals with type 2 diabetes.

This was a study of tirzepatide in participants with obesity or overweight. The main purpose was to learn more about how tirzepatide maintained body weight loss. The study had two phases: a lead-in phase in which all participants took tirzepatide and a treatment phase in which participants either continued tirzepatide or switched to placebo. The study lasted about 2 years (25 visits). Read Less

This is a study of tirzepatide in participants with obesity. The purpose of this study is to learn more about how tirzepatide maintains body weight or adds to weight loss after an intensive lifestyle modification program. The study will last about 2 years (29 visits). Read Less

This is a study of tirzepatide in participants with type 2 diabetes who have obesity or are overweight. The main purpose is to learn more about how tirzepatide affects body weight. The study will last 79 weeks (22 visits). Read Less
