Study Endpoints

Primary Endpoints

Change in Glycosylated Haemoglobin (HbA1c)
From baseline (week 0) to end of treatment (week 28)

Change in HbA1c from baseline (week 0) to end of treatment (week 28) is presented. The endpoint was evaluated based on the data from in-study period. The in-study period is defined as the uninterrupted time interval from date of randomisation to date of least contact with trial site.

Secondary Endpoints

Change in Body Weight
From baseline (week 0) to end of treatment (week 28)
Number of Treatment-Emergent Adverse Events (TEAEs)
From the time of first dosing (week 0) to end of study (week 33)
Occurrence of Anti-semaglutide Antibodies (Yes/no)
From baseline (week 0) to end of study (week 33)

ArmTypeDescription
Semaglutide JEXPERIMENTALParticipants will initially receive 0.25 milligrams (mg) subcutaneous injections of semaglutide J once weekly (OW) and the dose will be then escalated once in 4 weeks for 8 weeks until the target maintenance dose of 1.0 mg is reached which will be maintained for a period of 20 weeks. Metformin will be considered as background therapy during the trial.
Semaglutide BACTIVE_COMPARATORParticipants will initially receive 0.25 mg subcutaneous injections of semaglutide B OW and the dose will be then escalated once in 4 weeks for 8 weeks until the target maintenance dose of 1.0 mg is reached which will be maintained for a period of 20 weeks. Metformin will be considered as background therapy during the trial.

Frequently asked questions about Semaglutide J

What is Semaglutide J?

Semaglutide J is an investigational small molecule GLP-1 receptor agonist developed by Novo Nordisk A/S for the treatment of type 2 diabetes mellitus. It is in Phase 3 clinical development and has been studied in a completed active-controlled trial. It is not described as approved.

What is Semaglutide J used for in Diabetes Mellitus, Type 2?

Semaglutide J is being developed for the treatment of type 2 diabetes mellitus. Its clinical program has focused on comparing it with another semaglutide medicine in adults with type 2 diabetes. The studied population was adults 18 years and older, with no healthy volunteers enrolled.

What does Semaglutide J target?

Semaglutide J targets GLP1R, the glucagon-like peptide-1 receptor, and acts as a receptor agonist. GLP-1 receptor agonists are a recognized drug class in metabolic medicine. The completed Phase 3 study evaluated this small molecule in people with type 2 diabetes.

Who makes Semaglutide J?

Semaglutide J is developed by Novo Nordisk A/S, which trades under the ticker NVO. Novo Nordisk is the sponsor of the clinical program for this asset in type 2 diabetes mellitus.

What phase is Semaglutide J in?

Semaglutide J is in Phase 3 development. One Phase 3 trial has been completed, and no trials are currently listed as active. The program has enrolled 388 participants in total, and the drug is investigational rather than approved.

What clinical trials is Semaglutide J in?

Semaglutide J has been studied in NCT05478252, titled A Research Study to Compare Two Semaglutide Medicines in People With Type 2 Diabetes. This completed Phase 3 trial enrolled 388 participants across the United States, Canada, Poland, Slovakia, and South Africa. It was randomized, double-blind, and active-controlled.
