Who cannot take part

• Previous episode of pancreatitis
• Current treatment with a GLP-1 RA, where it is in the participant's best interests to continue the GLP-1 RA or where the treating physician or patient is not willing to discontinue this medication for a minimum of 4 weeks prior to randomisation and for the full duration of the trial (ie. 108 weeks if assigned to placebo)

• Type 1 diabetes
• Known allergy, intolerance, or contraindication to GLP-1 RAs
• Any disorder, which in the investigator's opinion might jeopardise subject's safety or compliance with the protocol
• Hyperkalaemia (serum potassium ≥5.0 mmol/L) at time of screening
• Life expectancy less than 6 months; To be included in any of the following DOMAINS the participant must met eligible for the PLATFORM (as listed above); MRA domain
• Currently pregnant or breast feeding, or intending to become pregnant; GLP-1 RA Domain
