The aim of this study is to evaluate safety, and tolerability of insulin LY3209590 following a single dose given to children with type 2 diabetes mellitus (T2DM). This will be the first study to evaluate LY3209590 in pediatric patients with T2DM.

Screening:

All participants will be screened up to 28 days prior to dosing.

Treatment and Assessment Period:

On Day 1, participants will receive a single 100-Unit subcutaneous dose of LY3209590 at the clinical research unit.

Follow up research visits will be performed on Days 3, 5, 7, 15, 29, 43, and 65. Blood sampling and safety assessments will be performed at each in clinic visit. Before each study visit, subjects will need to fast for at least 8 hours.

A follow-up telephone call will be performed on approximately Day 72. The total time for participation is the study is about 100 days.

The DISCOVERY Study is a new, national effort to learn about the causes of type 2 diabetes in children. DISCOVERY is for children 9-14 years old who are at higher risk of developing type 2 diabetes. We want to figure out why some children get type 2 diabetes and others do not.

This study wants to know about the problems that Black or African American teenagers with type 1 diabetes (T1D) and their families face. It also wants to see how these problems affect their feelings, behavior, and how they get along with others. The study will find out how well they can handle T1D and adapt to it. It will also learn how good things like being strong, family, and where they live might help young people who have to deal with hard things. This includes how well they handle their feelings, behavior, relationships, and T1D care.

The purpose of this study is to evaluate how safe and effective the drug Qsymia (Phentermine/Topiramate of Ph/T) is for children, adolescents, and young adults with hypothalamic obesity. We will also evaluate if Ph/T helps with weight loss and changes in hunger in patients with hypothalamic obesity.

If you are determined to be eligible, then your participation will last for approximately 8 months. Participants will be asked to complete up to 5 in-person visits and 5 telephone safety check-ins. During the study you will be randomly assigned to study drug (phentermine/topiramate) or placebo for 28 weeks.

You will complete study procedures including blood tests, ECGs, mobile cardiac outpatient telemetry, body composition scan, and questionnaires. Compensation and reimbursement of limited travel expenses is available.

Insulin therapy, commonly given as multiple daily injection therapy, is the only recommended treatment for Cystic Fibrosis Related Diabetes (CFRD). Traditional therapy for CFRD requires an intense daily effort related to diabetes care on top of the already burdensome management of Cystic Fibrosis. In this study, we will assess the safety and effectiveness of the iLet Bionic Pancreas, an automated insulin delivery system, which uses a continuous glucose monitor (CGM), an insulin pump, and a control formula that activates insulin delivery based on CGM glucose data.
