Description as written by the study sponsor.

Novo Nordisk is developing a combination therapy with the investigational drug NNC0480-0389 and an already approved medicine called "semaglutide" for the treatment of type-2 diabetes (T2D). It is expected that the combination will further improve the blood sugar control compared to semaglutide therapy alone. The study will investigate the influence of the combination of semaglutide and NNC0480-0389 on the blood levels of a birth control pill (a combined oral contraceptive consisting of ethinylestradiol and levonorgestrel) and paracetamol. Participants will get semaglutide and NNC0480-0389 as injection under the skin of their belly using a pen-injector. The injections will be given once weekly for 14 weeks. Additionally, participants will at two occasions get paracetamol as soluble tablet in connection with a standardised breakfast meal. Further, participants will get the birth control pill in form of tablets in two periods of 8 days each. Participants will get the combination of semaglutide and NNC0480-0389 as well as paracetamol and the combined contraceptive in any case. The study participation will last up to about 24 weeks. Participants will have 25 visits at the study centre. For 4 of the visits participants will stay at the study centre; the remaining visits will be outpatient. Only healthy postmenopausal women can take part in this study.
