Official Title
Effect of Tirzepatide on Progression of Coronary Atherosclerosis Using MDCT

Brief Summary
A multi-center, randomized, double-blind, placebo-controlled, parallel-group phase IV Study evaluating the effects of tirzepatide on atherosclerotic plaque progression assessed by coronary computed tomography angiography (CCTA) in participants with a diagnosis of type II Diabetes (T2DM) and atherosclerosis.

Detailed Description
This is a multi-center study in which 120 male and female participants who meet the eligibility criteria will be randomized. Study will assess changes in coronary atheroma volume comparing tirzepatide 15 mg/week plus Standard of Care (SOC), as compared to placebo plus SOC. Potential eligible participants may be prescreened for eligibility prior to the screening visit and must have a diagnosis of atherosclerosis (as assessed by >10% atheroma on CCTA) and T2DM.

Patients must be on a stable medical regiment (>4 weeks on statin therapy and diabetes medications) and undergo screening CCTA to demonstrate coronary plaque. Participant eligibility will be assessed by the Imaging Core Lab.

If the participant meets all entry criteria during baseline visit, then consenting participants will be randomized 1:1 to receive tirzepatide on top of standard of care for treatment period of 12 months. Participants will be asked to maintain stable doses of statins and diabetes medications. Persistent hyperglycemia will be treated by primary physician or endocrinologist.

t eligibility criteria. Approximately fifteen sites propose to enroll up to 420 couples (about 30 to 60 couples per site) with a goal of obtaining 200 couples completing the contraceptive efficacy phase of the study. The study has four phases (screening phase, suppression phase, efficacy phase and recovery phase) with monthly visits to provide the male participants with the NES/T gel, to encourage adherence, to monitor for possible side effects, and to quantify semen parameters. The female partner will be contacted monthly and come in for a visit every three months. Male subjects will be treated and followed as outpatients, along with their participating female partner.
