This is an interventional treatment trial for Glycogen Storage Disease Type III

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Key Inclusion Criteria:

  • Confirmed diagnosis of GSD III by gene sequencing or enzymatic testing

Inclusion Criteria for Participants Rescreening Into OL-RD Cohorts After Treatment with UX053 in SAD Cohort:

  • If a significant rise in ALT occurs after the prior dose, ALT should show a decreasing trend toward the subject's baseline value

Arm Description

Participants receive a single, peripheral intravenous (IV) infusion of UX053. After completion of the 90-day Follow up Period, participants can enter the open label repeat dose (OL-RD) cohort where they will receive UX053 every 4 weeks (Q4W) for 4 doses. Participants will also receive premedication, consisting of oral paracetamol/acetaminophen or ibuprofen, an H2 blocker, and an H1 blocker.

5. Study Description

Brief Summary
The primary objective of the study is to evaluate the safety of UX053 in adults with Glycogen Storage Disease Type III (GSD III).
Detailed Description
This study is a phase 1/2 first-in-human (FIH), study to evaluate the safety, tolerability, and pharmacokinetic (PK) of a single ascending dose (SAD) and repeat doses (RD) of UX053 in patients with GSD III. The SAD cohorts will be open-label (OL). There will be two types of RD cohorts, an open-label (OL-RD) and a randomized, double-blind (DB), and placebo-controlled (DB-RD).
