Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
One-arm intervantional study.
Patients with obesity , Body Mass Index (BMI) of 30 or more, or 27 or more and at least one weight-related complication, will be treated with tirzepatide , a dual agonist for the glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptors.
Administration: Once weekly via subcutaneous injection (SQ- self-administered by patient) with incremental dosage adjustments:The initial dosage of tirzepatide for treatment initiation will be 2.5 mg once weekly. After 4 weeks, the dose will be increased to 5 mg once weekly. Thereafter, the dose will ne escalated by 2.5 mg after at least 4 weeks on its dose. The maximum tirzepatide dosage will be 15 mg SQ once weekly.The total duration of tirzepatide administration for each participant will be 1 year.
Patients who will be unable to tolerate the dose escalation will continue on the maximum previously tolerated dose for the remainder of the study period.
Adherence to the intervention will be based on self-reporting by the participants.
