Conditions
Summary
This is a Phase 1/2, multicenter, open-label, single-ascending-dose study to evaluate the safety, tolerability, and efficacy of BEAM-301 in adult patients with GSDIa homozygous or compound heterozygous for the G6PC1 c.247C\>T (p.R83C) variant and to determine the optimal biological dose.
Eligibility
Inclusion Criteria3
- Males or females age ≥18 years of age at the time of consent.
- Diagnosis of GSDIa and homozygous or compound heterozygous for the G6PC1 c.247C>T (p.R83C) variant (confirmed by genetic testing).
- History of at least 1 episode of hypoglycemia <60 mg/dL within the 2 years prior to signing the ICF.
Exclusion Criteria7
- Liver transplant recipient/on waiting list for liver transplant or known history of liver cirrhosis.
- Presence of liver adenoma >5 cm in size based on liver MRI or liver ultrasound performed at screening or within 6 months prior to screening.
- Presence of liver adenoma >3 cm and ≤5 cm with a documented annual growth rate of ≥0.5 cm per year.
- Have aspartate transaminase or alanine transaminase >upper limit of normal (ULN).
- Total bilirubin levels >ULN; if documented Gilbert's Syndrome, total bilirubin >2 × ULN.
- Previous treatment with any cell-, gene-, or viral vector-derived therapy Hospitalization for management of hypoglycemia within 4 weeks prior to signing the ICF.
- Have triglycerides >1000 mg/dL or a history of pancreatitis or a history of acute pancreatitis within 5 years that does not have a known and corrected etiology (eg, cholecystectomy for gallstone pancreatitis).

Interventions
BEAM-301 is designed to correct the G6PC1 c.247C\>T allele via an A:T-to-G:C base-pair substitution, resulting in restoration of G6Pase-α catalytic activity.
