Gene Therapy With hLB-001 in Pediatric Patients With Severe Methylmalonic Acidemia
Stopped early · Phase 1/Phase 2
Conditions studied: Methylmalonic Acidemia
In brief
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.

Who can join
Age: 1 and older, up to 12. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- At the time of dosing, participants 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
- Screening serum/plasma methylmalonic acid level of >100 µmol/L
- One or more of the following considered by the PI to be MMA-related: (i) An unscheduled ER visit, hospitalization or requirement for sick day diet in the year prior to screening visit (ii) Developmental delay, movement disorder, optic neuropathy or feeding disorder with tube feeding requirement
- Medically stable for the 2 months prior to the start of screening
You may not qualify if…
