A Phase 4 interventional study of AI-Assisted Intensive Lifestyle Intervention and Tirzepatide in Obesity and Diabetes Mellitus, Type 2, sponsored by The First Affiliated Hospital of Anhui Medical University. Recruiting at 5 sites in China. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2026-11-04.
Sponsored by The First Affiliated Hospital of Anhui Medical University · Phase 4, Interventional, and Treatment
This multicenter randomized 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 participants will 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.
Participants will be randomly assigned to one of three groups: an AI-assisted intensive lifestyle intervention group, a tirzepatide treatment group, or a standard lifestyle management control group. The intervention period will last 52 weeks, followed by a 12-week post-intervention follow-up period. The main outcome is the percentage change in body weight at week 52. The study will also assess glycemic control, body composition, continuous glucose monitoring metrics, safety, and other metabolic outcomes.
11,522 studies on the registry are indexed under Obesity; 2,033 are open to participants now.
This study's planned enrollment of 285 is above the median of 67 across 9,006 interventional studies indexed under Obesity.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Started Jul 2026 (actual). Primary completion is estimated for Oct 2027, 15 months after the start.
Of 190 non-industry phase 4 interventional studies under Obesity, half reached primary completion within 32 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 52. This study's planned 15 months is below that.
Counting every sponsor, half of 210 studies reached it within 31 months; a quarter within 15 and three quarters within 51.
How these figures are worked out, and which studies are left out of them.
