A Research Study of the New Medicine NNC0519-0130 in Male Chinese Participants Living With Excess Body Weight

Investigation of Pharmacokinetics, Safety and Tolerability of Multiple Subcutaneous Doses of NNC0519-0130 in Male Chinese Participants With Overweight or Obesity

Novo Nordisk is developing a new study medicine NNC0519-0130 to improve the treatment options for people living with type 2 diabetes and excess body weight. In this study, the concentration of NNC0519-0130 in the blood will be measured and its safety will be evaluated. The participants will either get NNC0519-0130 or placebo (a "dummy" substance), which treatment the participants get is decided by chance. This study will test up to 7 different doses of NNC0519-0130 and will last for about 28 weeks.

Exclusion Criteria:

• Any disorder which in the investigator's opinion might jeopardise participant's safety or compliance with the protocol.
• Presence or history of any clinically relevant respiratory, metabolic, renal, hepatic, cardiovascular, gastrointestinal, or endocrinological conditions.
