Safety, Tolerability and Efficacy of Semaglutide Depot in Subjects With Type-2 Diabetes Mellitus

Study Title:

A Prospective, Multicenter, Open-Label, Dose Escalation Phase I/Ila Study to Assess the Safety, Tolerability, and Efficacy of Semaglutide Depot in Subjects with Type 2 Diabetes Mellitus

Background:

Type 2 diabetes mellitus (T2DM) is a chronic condition in which the body cannot properly use insulin, leading to elevated blood glucose levels. It is often associated with overweight or obesity and can lead to serious complications if not well controlled.

Semaglutide, is a GLP 1 receptor agonist, that helps lower blood glucose by increasing insulin secretion, reducing glucagon (a hormone that raises blood glucose), slowing gastric emptying, and reducing appetite. In addition to improving glycemic control, it also supports weight loss and has demonstrated cardiovascular benefits. Semaglutide is already approved in several formulations (examples: Ozempic® for type 2 diabetes and Wegovy® for weight management), but these require once-weekly injections.

Semaglutide Depot (SG Depot) is a new, long-acting formulation developed by Mapi Pharma Ltd. It is designed to be injected once every 4 weeks (once monthly), which may make treatment easier and improve adherence for people with diabetes.

Study Design:

• Dose escalation: will be allowed only after review of safety data

Inclusion criteria

• Adults aged 18-64 years with T2DM, BMI 25-35 kg/m2
