Type 2 diabetes mellitus (T2D) is a condition that affects insulin production. Without insulin, the body’s cells cannot absorb glucose (the body’s blood sugar needed to produce energy in the cells). 
GLP-1 is a natural gut hormone that is made by the body in response to meals. What GLP-1 does is boost the production of insulin to help manage blood sugar levels. Researchers are interested in finding the best way to give this hormone to people with diabetes. This research study seeks to compare the effects of the potential gut hormone treatment when given into a vein (intravenous) or infused under the skin (subcutaneous). 

• Participants will be contributing valuable information that may benefit those with type 2 diabetes in the future.
• Participants will be compensated up to $400 for participating in this study.  
• Participants will be helping to advance type 2 diabetes treatment research.

• Men and women aged 18 to 79 years old who are diagnosed with type 2 diabetes (T2D)
• Must be treated for diabetes with long-acting insulin (glargine e.g., Lantus, Semeglee, Toujeo, Optisulin) or premixed insulin (e.g. Humalog Mix, Humulin 30/70, Mixtard, or NovoMix) together with any of the following:
  • Diet
  • Metformin (some brand names include: Metformin, Diaformin, Diabex, Formet, Metex)
  • Sulfonylurea, thiazolidinedione, SGLT2 inhibitor, alpha-glucosidase inhibitor
  • Mealtime insulin injections
• Must not be currently taking a DPP-4 inhibitor (e.g., Januvia, Janumet, Onglyza, Trajenta, Trajentamet, Galvus, Galvument), a GLP-1 receptor agonist (e.g., Bydureon, Byetta, Lyxumia, Trulicity, Saxenda, Victoza, Ozempic), or Ryzodeg

• Must have a recent HbA1c current test result of >7% (if available)
• Must have a stable weight in the last 3 months
• Must be able to attend 2 study visits at the Clinical Research Facility of the Adelaide Health and Medical Sciences (AHMS). The visits will take place approximately 1 week apart 

• Participation in this study involves answering questionnaires. 
• Participation in this study will involve blood tests and injections.
• Participants will be given a ‘take-home’ meal which is to be eaten in the evening (around 7 pm) prior to the study visit. Participants may drink water with the meal. After the meal, participants will be required to fast from solids and liquids until the following morning. The study team can explain more about this.
