This is a Phase 1/2, multinational, open-label, escalating-dose study to evaluate the safety and efficacy of an intravenous infusion of GNT0003 in patients with Crigler-Najjar aged ≥10 years and requiring phototherapy. Patients will received a single administration of GNT0003 and will be followed for safety and efficacy of approximately 60 months (5 years):
- a follow-up of approximately 12 months (48 weeks)
- a long term follow-up of approximately 48 months (4 years), in order to be in line with the latest EMEA Guideline on follow-up of patients administered with gene therapy medicinal products, released on 22 Oct.2009 by the Committee for medicinal products for human use.

|Estimated Study Completion Date :||December 27, 2026|
2 doses of the IMP assessed in a dose escalation, open-label, phase 1/2 study
Intravenous infusion, single dose
- Incidence of Adverse Events / Serious Adverse Events (Safety) : All Treatment Emergent Adverse Events, all Serious Adverse Events [ Time Frame: 12 months ]
Incidence of AE/SAE evaluated by changes in laboratory parameters, vital signs, physical examination, reported from baseline to each visit, evaluated for each dose and for the study as a whole. Clinically relevant abnormal findings on Laboratory values, Vital Signs, Physical findings will be reported as Adverse Events.
Incidence and Severity of Adverse Events for each body system will be presented for each dose level and summarized overall.
- Decrease of total Serum bilirubin level after interruption of daily phototherapy (Efficacy) [ Time Frame: 4 months ]Serum total bilirubin ≤ 300 µmol/L, 7 days after interruption of daily phototherapy occuring at week 16 after the administration of GNT0003.
- Quality of life assessment [ Time Frame: 60 months ]- Scale 36-Item Short Form Survey (SF-36 Health Survey for adults). Outcome measure: change of quality of life from Baseline to Week 24, Week 48 and yearly up to 48 months after IMP administration.
- Quality of life assessment [ Time Frame: 60 months ]- Scale 10-Item Short Form Survey (SF-10 Health Survey for children). Outcome measure: change of quality of life from Baseline to Week 24, Week 48 and yearly up to 48 months after IMP administration.
