At CureGSD1b our primary goal is to help develop new therapies, treatment options, and eventually a cure for GSD1b. There are steps that we are taking as an organization that will help enable this, including the implementation of an online Patient Contact Registry, as well as the Rare-X Data Collection Program. We have a small patient population, but one that spans the globe. This is an easy way to make our data accessible to researchers across the globe. The more participation and more diversity the more useful this will be for us and for researchers. If you are a patient or caregiver, please register for both here.
If you are a researcher looking for access to our data, please reach out to Jamas LaFreniere at jamas@sophieshopefoundation.org

mRNA replacement therapy presents a great treatment opportunity for GSD1b and is an area of focus for CureGSD1b. We are currently working closely with Dr Brunetti-Pierri on the mouse study. For a basic explanation of how this therapy can work in rare disease, click here.
Gene editing aims to be a one-time therapy that directly edits pieces of DNA within the cell. It’s considered a type of gene therapy, which is the use of genetic material to treat or prevent disease. Gene editing has great potential to cure rare genetic diseases like GSD1b. Learn more here about gene editing: click here.
Prime editing is a more specific form of gene therapy that uses enzymes to alter DNA. It is also considered a type of gene therapy. Prime editing is a versatile and precise genome editing method that directly writes new genetic information into DNA. For more information about the technology, click here.
Specific to GSD1b, Prime Medicine announced in October of 2023, the first-ever successful data in non-human primates of prime editing being used to correct one GSD1b mutation. Read Prime’s announcement here.
Adeno-associated virus (AAV) is a non-enveloped virus that can be engineered to deliver DNA to target cells. These vectors introduce therapeutic genes into patient cells to treat diseases, especially genetic disorders. Learn the basics of vector-based therapies like AAV here.
On March 3rd, 2022 we had the honor of hosting a Patient-Led Listening Session with the United States Food and Drug Administration. These sessions are granted after application from a patient organization, which in this case was Sophie’s Hope Foundation and CureGSD1b. The intent of the session is for rare disease organizations to educate the FDA on the disease and challenges associated with it either as a patient or caregiver. Every office within the FDA was represented and the feedback regarding our session was very encouraging. Below you will find all the material from our session.
