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.

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.
Sequence A: Semaglutide J-Semaglutide C-Semaglutide JEXPERIMENTALAfter 6 weeks of run-in dose escalation period participants will orally receive semaglutide J at dose level 1 once daily for 4 weeks followed by semaglutide C once daily for next 4 weeks and thereafter semaglutide J at dose level 3 once daily for next 4 weeks.
Sequence B: Semaglutide C-Semaglutide J-Semaglutide JEXPERIMENTALAfter 6 weeks of run-in dose escalation period participants will orally receive semaglutide C once daily for 4 weeks followed by semaglutide J at dose level 2 once daily for next 4 weeks and thereafter semaglutide J at dose level 4 once daily for next 4 weeks.
Sequence C: Semglutide J-Semaglutide J-Semaglutide CEXPERIMENTALAfter 6 weeks of run-in dose escalation period participants will orally receive semaglutide J at dose level 1 once daily for 4 weeks followed by semaglutide J at dose level 3 once daily for next 4 weeks and thereafter semaglutide C (2x dose) once daily for next 4 weeks.
Sequence D: Semaglutide J-Semaglutide C-Semaglutide JEXPERIMENTALAfter 6 weeks of run-in dose escalation period participants will orally receive semaglutide J at dose level 2 once daily for 4 weeks followed by semaglutide C (2x dose) once daily for next 4 weeks and thereafter semaglutide J at dose level 4 once daily for next 4 weeks.

Frequently asked questions about Semaglutide J

What is Semaglutide J used for in Type 2 Diabetes?

Semaglutide J is an investigational small molecule being developed by Novo Nordisk for the treatment of Type 2 Diabetes Mellitus. It is currently in Phase 3 clinical development. A completed Phase 3 trial compared two semaglutide medicines in people with Type 2 Diabetes, with 388 participants enrolled.

What does Semaglutide J target?

Semaglutide J is a small molecule developed by Novo Nordisk. Its molecular target has not been disclosed in available information. The drug is being studied for its effects in Type 2 Diabetes and in healthy participants to assess blood levels of oral semaglutide.

Who makes Semaglutide J?

Semaglutide J is developed by Novo Nordisk A/S, a pharmaceutical company listed on the stock exchange under the ticker NVO. The company is conducting clinical trials to evaluate the drug for Type 2 Diabetes and in healthy participants.

What phase is Semaglutide J in?

Semaglutide J is in Phase 3 clinical development for Type 2 Diabetes Mellitus. It has received FDA accelerated approval designation. The drug is investigational and not yet approved for commercial use. A Phase 3 trial has been completed, and a Phase 1 trial in healthy participants has also been completed.

What clinical trials is Semaglutide J in?

Semaglutide J has been studied in two completed trials. NCT05478252 is a Phase 3 study comparing two semaglutide medicines in Type 2 Diabetes, enrolling 388 participants across the US, Canada, Poland, Slovakia, and South Africa. NCT05784402 is a Phase 1 study in healthy participants measuring blood levels of oral semaglutide, enrolling 264 participants in the US and Canada.

Is Semaglutide J the same as oral semaglutide?

Semaglutide J appears to be related to oral semaglutide, as a Phase 1 trial studied how much semaglutide is found in the blood with different tablets of oral semaglutide in healthy participants. However, the exact relationship between Semaglutide J and oral semaglutide is not fully detailed in available information.
