Beskrivelse
Inclusion Criteria:
- Participants who have completed the LUNA study through Month 24 and, in the Investigator's judgment, may benefit from continued treatment or observational follow-up
- Be adults (≥18 years old) who are able to provide informed consent OR minors (8 to <18 years old) providing assent with parental permission
- Participant (and/or parent/caregiver) willing and able to comply with the 24-month protocol, attend all study visits, and complete all assessments
- Treatment Cohort only: Non-pregnant and non-breastfeeding. Women of childbearing potential (WOCBP) and fertile males must use highly effective contraception
Exclusion Criteria:
Treatment Cohort only: New ocular condition in the SE (e.g., severe infection, uncontrolled glaucoma, or retinal detachment) that, in the Investigator's opinion, makes the SE unsafe for IVT injection
- Additionally, any ocular condition or AE in the fellow eye that, in the opinion of the Investigator, may impact participant safety or confound the assessment of the SE. Eligibility in such cases will be evaluated on a case-by-case basis.
- Treatment Cohort only: Known hypersensitivity to antisense oligonucleotides or any constituents of the injection
- Treatment Cohort only: Any clinically significant safety finding observed during the LUNA trial that, in the Investigator's opinion, compromises the participant's safety with continued dosing. Participants that have had study drug temporarily withdrawn or elective ocular surgery or AESI's during the LUNA trial may be reviewed on a case by case basis for eligibility into the Treatment Cohort (Note: These participants may still be eligible for the Observation Only Cohort at the Investigator's discretion and following discussion with medical monitor).
- Both cohorts: Presence of any significant ocular or systemic disease, or laboratory abnormality, that would increase participant risk irrespective of treatment or interfere with study assessments
- Both cohorts: Participation in any other interventional clinical trial involving an investigational drug or device during the course of the CAPELLA study

Eksperimentel: Ultevursen 180/60 μg
Participants will receive an intravitreal injection (IVT) of Ultevursen with concentrations of 3.6 mg/mL for initial dose and 1.2 mg/mL for maintenance doses every 6 months thereafter through Month 18 (up to 4 doses).
The dose concentrations will be determined by the participant's randomized cohort assignment during the Phase 2 LUNA study.
|
Participants will receive up to 4 doses over a 24-month period
|
|
Andet: Observation Only
Participants who are assigned to the Observation Only Cohort will not receive active study treatment via intravitreal injection (IVT), but will be asked to visit the trial location at Screening/Baseline, Months 12 and 24 for safety follow up and other study-related tests.
|
Observation only (no experimental drug administered)
