The SUNRISE trial is a first-in-human (FIH), open-label, Phase 1/2 clinical trial designed to assess the safety, tolerability and preliminary efficacy of a single intravenous infusion of hLB-001 in pediatric patients with MMA characterized by methylmalonyl-CoA mutase gene (MMUT) mutations. hLB-001 is a liver-targeted, recombinant engineered adeno-associated viral (rAAV) vector utilizing the LK03 capsid (rAAV-LK03), designed to non-disruptively integrate the human methylmalonyl-CoA mutase gene at the albumin locus.
The trial is expected to enroll pediatric patients with ages ranging from 6 months to 12 years, initially starting with 3 to 12 year-old patients and then adding patients aged 6 months to 2 years.

| Ages Eligible for Study: | 6 Months to 12 Years (Child) |
| Sexes Eligible for Study: | All |
| Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- At the time of dosing, patient must be 6 months to 12 years of age
-
Males and females with diagnosis of severe MMA meeting all the following;
- Isolated MMA with genetically confirmed, pathogenic mutations in the MMUT gene
