Real-World effectiveness, safety, and Patient-Reported outcomes of tirzepatide in adults with type 2 diabetes mellitus, obesity, or prediabetes in pakistan: a multicentre, prospective, observational cohort study
NCT ID NCT07809568
First seen Sep 09, 2026 · Last updated Sep 09, 2026
Summary
This is a multicentre, prospective, observational study of the medicine tirzepatide as it is used in routine clinical care in Pakistan. Tirzepatide is already approved for type 2 diabetes and for obesity, but there is very little information on how it works for people in South Asia, and none from Pakistan specifically. This study aims to fill that gap. The study will follow 330 adults who are starting tirzepatide as part of their normal treatment, across ten diabetes and endocrinology centres in Pakistan. Everyone taking part has obesity, and they are grouped into three cohorts based on their blood sugar status at the start: obesity without diabetes, prediabetes with obesity, and type 2 diabetes with obesity. The study does not change anyone's treatment. The treating doctor decides whether to prescribe tirzepatide, at what dose, and for how long. The study simply observes and records what happens over 24 weeks, with assessments at the start, at Weeks 12 to 14, and at Weeks 24 to 26. The main things measured are the change in blood sugar control (HbA1c) in the diabetes cohort, and the change in body weight in the obesity and prediabetes cohorts. The study also looks at changes in blood pressure, cholesterol, and other measures, how well people stay on treatment, any side effects, and how participants feel about their treatment and quality of life. The findings will help doctors understand how tirzepatide performs in real-world care in Pakistan and inform its use in similar populations.

Who is studied
Adults aged 18 years or older with obesity (BMI ≥ 30) who are initiating tirzepatide as part of routine clinical care at ten diabetes and endocrinology centres in Pakistan. Participants are grouped into three cohorts by glycaemic status at entry: obesity without diabetes (HbA1c \< 5.7%), prediabetes with obesity (HbA1c 5.7-6.4%), and type 2 diabetes with obesity (diagnosed at least 6 months prior).
