Phase 2: testing LY3305677 for Obesity

The purpose of this Phase-2 chronic weight management master protocol (CWMM) is to create a framework to measure the safety and how well it works of various investigational interventions for chronic weight management with intervention-specific appendices (ISAs). The CWMM establishes entry criteria for newly enrolled participants across the master and the ISAs.

Phase 3: testing Mirikizumab for Ulcerative Colitis

The main purpose of this study is to show whether in these individuals, treatment with both mirikizumab and tirzepatide, compared with treatment with mirikizumab and dummy treatment (placebo), leads to decrease or disappearance of UC symptoms, and loss of at least one-tenth of the overall body weight. Participation in this study will last up to 61 weeks, including 52 weeks of treatment.

Phase 2: testing Glucagon-like peptide 1 receptor agonist for Endometrioid Endometrial Adenocarcinoma

This study will explore the use of glucagon-like peptide 1 receptor agonist (GLP-1RA) used concurrently with levonorgestrel intrauterine device in patients with poor surgical candidacy for a hysterectomy or patients who are pursuing fertility sparing.

Phase 3: testing Tirzepatide for Metabolic Dysfunction-Associated Steatotic Liver Disease

The main purpose of the SYNERGY-OUTCOMES study is to find out whether retatrutide and tirzepatide can prevent major adverse liver outcomes (MALO) in people with high-risk metabolic dysfunction-associated steatotic liver disease (MASLD). The study will enroll adults who have MASLD based on non-invasive tests (NITs), which indicate they are more likely to develop MALO.

Phase 2: testing ALN-PNP for Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD)

This study will test a study drug called ALN-PNP with and without another drug that is used for controlling blood sugar, appetite, and weight (for example, tirzepatide), to see if it can help treat MASLD, also known as fatty liver disease. ALN-PNP reduces the amount of Patatin-like phospholipase domain-containing protein 3 (PNPLA3), a protein that liver cells make, which may help decrease liver fat if there is an abnormal PNPLA3 protein.

Not a traditional drug phase: testing Tirzepatide (Per-label titration) for Obesity

The goal of this clinical trial is to determine whether a flexible, symptom-guided titration strategy for tirzepatide can help adults with obesity without diabetes stay on treatment longer, while maintaining weight-loss effectiveness. The main questions it aims to answer are: * Does flexible, symptom-guided titration increase time on treatment (delay treatment discontinuation) compared with standard per-label titration over 76 weeks?

This multicenter randomly assigned controlled trial will evaluate whether an AI-assisted intensive lifestyle intervention can improve weight and glycemic management in adults with obesity and newly diagnosed type 2 diabetes, compared with tirzepatide treatment and standard lifestyle management. Eligible you would be adults aged 18 to 65 years with a body mass index of 28 to less than 40 kg/m² and newly diagnosed type 2 diabetes who have not used glucose-lowering medications in the past 3 months.

Phase 4: testing Dual GIP/GLP-1 Receptor Agonist Tirzepatide for Obesity (BMI>30)

Incretin-based pharmacotherapies induce significant weight loss and represent a paradigm shift in obesity treatment. However, particularly fast weight loss may be accompanied by a significant loss of muscle mass, which is associated with a reduced metabolic rate at rest and during physical activity, increased insulin resistance, limited mobility, and potential long-term adverse effects.

Phase 1: testing Tirzepatide for Lung Cancer

The proposed study seeks to address a critical gap in the management of lorlatinib-induced metabolic derangements, particularly rapid weight gain, which can adversely affect treatment adherence, dosing and ultimately patient outcomes. In this study patients with non-small cell lung cancer (NSCLC) receiving lorlatinib treatment will receive tirzepatide, a dual GIP/GLP-1 receptor agonist with demonstrated how well it works in weight reduction and metabolic improvement.

Not a traditional drug phase: testing GLP-1 receptor agonist (e.g., semaglutide, tirzepatide) - prescribed by the treating physician as standard care; the study does not assign or alter treatment. for Obesity

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and dual GLP-1/GIP agonists such as semaglutide and tirzepatide produce marked weight loss in people with obesity, with reported reductions of about 15-20%. Rapid weight loss may reduce not only fat mass but also lean body mass and skeletal muscle mass, raising concern about sarcopenia and sarcopenic obesity.
