Blood Sugar Stability in Individuals with Hyperinsulinism

The purpose of the study is to evaluate blood sugar levels and beta-cell function in adolescents and adult with KATP hyperinsulinism whom did not undergo pancreatectomy. We will perform oral glucose tolerance tests, glucose potentiated arginine tests, and evaluate blood sugars in home environment by using continuous glucose monitoring for 10 days.

Designate - Siplizumab in T1DM

The goal of this study is to identify a safe dosing regimen for siplizumab in participants with type 1 diabetes. Siplizumab is a drug used to help treat recent onset type 1 diabetes mellitus (T1DM). This study is interested in participants aged 18-45 years with T1DM, who are within 18 months of receiving their diagnosis. Participants will be randomized (selected at random by the study team) to one of four possible treatment groups. All groups will receive weekly siplizumab doses administered subcutaneously (injected into the body through the skin) for a total of 12 weeks.

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.

Living with Diabetes: Challenges for Black Teens

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.

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 Individuals with Hyperinsulinism/Hyperammonemia

Our team is working on a study to better understand neurological problems, including seizures and developmental delays, that occur in many individuals with HI/HA syndrome. 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 four 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.
