Summary
This study will be an open-label, prospective, interventional feasibility pilot project to study the efficacy, safety, and tolerability of UX007 (triheptanoin) on reducing hypoglycemic events in patients with GSD I. Subjects will serve as their own control. Five (5) subjects who are treatment naïve to UX007 (triheptanoin) and are already on standard dietary therapy for GSDI will be enrolled. The primary objective is to evaluate the efficacy, safety, and tolerability of UX007 (triheptanoin) in patients with GSD I. The secondary objectives include evaluating the effect of UX007 (triheptanoin) on maintaining the duration of normoglycemia between meals based on glucose monitoring (Preventing and reducing the frequency of hypoglycemia); reduction/stabilization of the dose of cornstarch; and the prevention of increased liver steatosis based on ultrasound with elastography.

Criteria
Inclusion Criteria:

- Naive to UX007 (triheptanoin)

- Confirmed documented diagnosis of GSDI: confirmation may be based on mutation
analysis, liver biopsy, or enzyme testing

- Willing and able to complete all aspects of the study through the end of the study,
including visits and tests, documentation of symptoms, blood sugar and dietary log,
and administration of UX007 (triheptanoin); minors in the study must have a
parent/legally authorized representative who is willing and able to assist in all
applicable study requirements

Exclusion Criteria:

- Have a history of severe inflammatory bowel disease, or severe chronic diarrhea per
the PI discretion on conventional doses of cornstarch

- Patient is on any other form of medium chain triglyceride (MCT) during the time of the
study. Patients will be asked to stop any nutritional compound that includes MCT oil
one week (7 days) prior to baseline.

- Have any co-morbid conditions, including major organ-system disease(s) that in the
opinion of the Investigator, places the subject at increased risk of complications,
interferes with study participation or compliance, or confounds study objectives

- Pregnancy

- Patients on continuous feeds, with a diagnosis of diabetes, and/or a diagnosis of any
other inborn error or metabolism
