Summary

This trial tests a new drug, LY3938577, to see if it is safe for healthy people and those with Type 2 Diabetes. The study will check how well people tolerate the drug over several weeks.

Who is the study for?
This trial is for healthy adults and those with Type 2 Diabetes Mellitus (T2DM). Healthy participants should have a BMI of 18.5-32 kg/m², while T2DM participants can have up to 40 kg/m². T2DM should be diagnosed over a year ago. People with severe eye or nerve complications, recent steroid therapy, or participation in another study recently cannot join.
What is being tested?
The safety and tolerability of LY3938577 are being tested on two groups: healthy individuals and those with T2DM. Part A involves a single dose for both types of participants; Part B gives multiple doses to only the T2DM group. The study compares LY3938577 against Insulin degludec and placebo over approximately six to ten weeks.
What are the potential side effects?
While specific side effects aren't listed here, common ones from diabetes medications may include low blood sugar levels, weight gain, nausea, injection site reactions, headache, upper respiratory tract infections and potential allergic reactions.

Other Research
Common treatments for Type 2 Diabetes include GLP-1 receptor agonists, SGLT2 inhibitors, DPP-4 inhibitors, and thiazolidinediones. GLP-1 receptor agonists enhance insulin secretion and inhibit glucagon release, improving blood glucose control and promoting weight loss. SGLT2 inhibitors reduce blood glucose by preventing glucose reabsorption in the kidneys, leading to its excretion in urine. DPP-4 inhibitors prolong the action of incretin hormones, which increase insulin release and decrease glucagon levels. Thiazolidinediones improve insulin sensitivity by acting on fat cells to increase glucose uptake. These mechanisms are crucial for Type 2 Diabetes patients as they target different aspects of glucose regulation, offering comprehensive management of the disease.
