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

Min Age: 18 Years

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

DRUGBEAM-301: Single dose of BEAM-301 administered by IV

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.
