Canagliflozin in Children with Type 2 Diabetes

The goal of this study is to investigate the efficacy and safety of Canagliflozin (which is experimental) in children and adolescents ages 10 to 18 years old with Type 2 diabetes and poor control (i.e., an HbA1c of 6.5% to 10.5%). Study drug or placebo would be taken alone or with metformin or insulin as needed. Monitoring tests include blood, urine, physical exams, vital signs, blood sugar and ketone monitoring, diabetes management counseling.

Childhood Type 2 Diabetes Study of a Single Dose of "LY3209590" a Weekly Insulin Injection

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.

Dasiglucagon for the Treatment of Children with Congenital Hyperinsulinism (for children under 1 year of age)

This study is a randomized, double-blind, placebo-controlled study that will evaluate the safety and efficacy of dasiglucagon in children between the ages of 7 days and 12 months who have congenital hyperinsulinism. Dasiglucagon will be given as a subcutaneous infusion while patients are admitted to the hospital. Other treatments for hyperinsulinism may be changed as allowed while maintaining safe blood sugar levels. For the second part of the study, patients may be able to go home on the medication.

DTX401 Gene Therapy in Glycogen Storage Disease (GSD) Type Ia

Our team at the Congenital Hyperinsulinism Center at CHOP is working on a research study to determine whether an experimental gene therapy product, DTX401, is safe and effective in people with glycogen storage disease type Ia (GSDIa). The FDA has not approved this drug for the treatment of GSDIa but has approved us to use this drug as part of this clinical trial. The purpose of this research study is to see if DTX401 can help people with GSDIa have normal blood sugar levels and fewer episodes of hypoglycemia. DTX041 works by delivering copies of the G6PC gene to your liver through a one-time infusion. Participation in this study will last for 2 years and will involve 30 study visits. It is possible that treatment with the study drug infusion may improve your blood sugar levels. Travel costs will be covered by the study and you will receive compensation for participating.

Moderna mRNA Clinical Trial for Patients with GSD 1a

Our team has partnered with Moderna on a clinical trial for patients with glycogen storage disease type 1a (GSD1a). We would like to invite you to take part in a clinical trial for an mRNA investigational drug that could potentially correct the cause of GSD1a, by teaching your body to break down glycogen, correct low glucose, and avoid starch intake. The purpose of this trial is to see if a new investigational mRNA study drug, called mRNA-3745, is safe and if it works in the way researchers expect. mRNA technology uses messenger ribonucleic acid (mRNA), an instructional molecule that naturally occurs in the body and carries information to cells. In this case, we are studying if mRNA-3745 given through an IV infusion can instruct the body to make the protein that is missing in people with GSD1a.

mRNA-3725 is not approved by the FDA; the FDA has allowed us to provide this investigational medicine to patients enrolled in this phase 1/2 trial. Phase 1/2 clinical trials like this one aim to test the safety, side effects, and best dose of an investigational medication. In the phase 2 part, participants usually receive the highest dose of treatment discovered in the phase 1 part. This is the first study in which humans are administered this study drug.

If successful, mRNA-3745 would enable certain organs in the body to effectively break down glycogen and avoid low glucose levels and starch intake. If mRNA-3745 could correct the cause of GSD1a, it would help keep your glucose levels where they need to be all the time.

Participation in this clinical trial could last up to approximately two years, depending on which stage you enroll in and whether or not you decide to participate in the long-term follow-up period of the study. Some of the visits in this trial will require you to stay overnight at the hospital, and some of the visits will require you to visit the hospital or doctor's office. Most of the visits in this clinical trial can be done at your home, where a home health nurse will perform the assessments needed.

All study-related procedures, travel, and compensation are provided.

Phenotypes of Congenital Hyperinsulinism

Congenital Hyperinsulinism is the most common cause of low blood sugar (hypoglycemia) in infants and children.Infants who are born with this problem have low blood sugar, which can cause seizures or brain damage.

We are doing this study to see if the patterns of abnormalities in controlling insulin in children and adults with hyperinsulinism are related to any underlying genetic cause and to identify possible new genetic causes.This will be done by standard clinical tests of insulin control: a glucose tolerance test, a protein tolerance test, and a fasting test.

Research Study for Individuals with Hyperinsulinism, Type 1 Diabetes Mellitus, and Healthy Children

Our team is working on a study to better understand neurological problems, including seizures and developmental delays, that occur in children with hyperinsulinism, including HI/HA syndrome, and type 1 diabetes mellitus. The study involves a one-day visit to The Children's Hospital of Philadelphia and The University of Pennsylvania for a specialized magnetic resonance imaging scan (MRI) of the brain, an electroencephalogram (EEG), blood draw, and completion of questionnaires to evaluate development and behavior. The entire study visit is expected to take about five hours. If you are interested in learning more, please contact us at HIResearch@email.chop.edu.

Research Study for Patients with GSD III

You or your child are being asked to take part in this research study because you have Glycogen Storage Disease Type III (GSD III). The purpose of this research study is to better understand blood sugar variability, muscle strength and function, and impact of Glycogen Storage Disease Type III (GSD III) on overall health. You will not receive any treatment for your GSD III as part of this study, but the information you provide will be helpful for the study sponsor, Ultragenyx Pharmaceutical Inc., to develop a new therapy for GSD III.

If you agree to take part, your participation will last for about 26 weeks and will involve up to 2 study visits to the hospital along with up to 26 phone calls. There will be no changes to your treatment regimen for GSD III as part of this study.

As a participant in the research you will:

  • come to the hospital for 1-2 in person visits to complete interviews and questionnaires,
  • wear a blinded continuous glucose monitor (CGM) 3 months and an unblinded CGM for 3 months,
  • complete fingerstick blood sugar checks, maintain a nutrition diary for 3 or more weeks throughout the study,
  • maintain a hypoglycemia symptom diary, and
  • upload CGM and HHG device data to a study-provided laptop weekly.

The main risks of this study are from hypoglycemia related to your diagnosis of GSD III and a loss of confidentiality. There are no direct benefits to you for participating in this study but the information collected as part of this study will help researchers better understand GSD III.
