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 goals of this research study are to find out how having COVID-19 recently affects blood sugar, inflammation, and insulin in people with type 1 and type 2 diabetes. We also want to see if COVID-19 changes blood vessel health or makes blood clot more easily. We will also look at how things like genes, lifestyle, and environment might affect these issues.

The goal of this Phase 2 study is to assess safety and efficacy of frexalimab to preserve -cell function in participants with newly diagnosed type 1 diabetes (T1D). In Part A, an exploratory part, adults (ages 18-35) will be treated with either high dose frexalimab, or placebo (inactive study drug). In Part B, adolescents and young adults (ages 12-21) will be treated with 3 dose levels of frexalimab or placebo.

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.

We are trying to learn more about the ways in which adolescents (12-17 years) are involved in decision making related to their chronic condition. We are hoping to partner with families who are planning to attend or recently attended a visit in the Comprehensive Sickle Cell Center, Diabetes Center for Children, Center for Inflammatory Bowel Disease, or the Division of Rheumatology at CHOP.

If you and your child are able to help us, you will each be asked to complete a questionnaire about your experiences during a recent clinic visit. Additionally, a random selection of parents and teens will be asked to complete an interview with our team. All participants will be compensated for their participation in this study.

It is essential that we speak to families before or immediately following their scheduled visit at CHOP.

The purpose of this study is to evaluate the safety and pharmacokinetics (drug levels in the blood) of teplizumab in children less than 8 years old. The study will also assess if your child stays in Stage 2 T1D or progresses to Stage 3 T1D. Your child may join the study only if they are in Stage 2 T1D. Previous studies in adults and children older than 8 years of age suggest that taking teplizumab, a drug that affects your childs immune system, may stop, delay, or decrease the attack on the cells that make insulin. This slowing or blocking of the immune attack may reduce the risk of short-term and long-term consequences of T1D. To join this study, your child must have been diagnosed with Stage 2 T1D based on two positive T1D-related antibodies and confirmed dysglycemia (abnormal blood sugar levels) based on an oral glucose tolerance test, fasting plasma glucose test, or an increase in a blood test called the hemoglobin A1c. The study is open-label. That means that if your child qualifies for the study, your child will receive teplizumab. There is no placebo in this study.

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.
