About this trial

This is an interventional treatment trial for Leber Congenital Amaurosis 10 focused on measuring LCA10, CEP290, p.Cys998X, c.2991+1655A>G, Leber Congenital Amaurosis, Antisense oligonucleotide, RNA therapy, QR-110, sepofarsen, pediatric, children

Eligibility Criteria

0 Years - 7 Years (Child)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Male or female child, <8 years of age at Screening with a clinical diagnosis of LCA and a molecular diagnosis of homozygosity or compound heterozygosity for the CEP290 p.Cys998X mutation, based on genotyping analysis at Screening. A historic genotyping report from a certified laboratory are acceptable with Sponsor approval.
  • BCVA equal to or better than Logarithm of the Minimum Angle of Resolution (logMAR) + 4.0 (Light Perception), and equal to or worse than logMAR + 0.4 in the treatment eye.
  • Detectable outer nuclear layer (ONL) in the area of the macula.

Exclusion Criteria:

  • Presence of any significant ocular or non-ocular disease/disorder which may put the subject at risk because of participation in the trial' may influence the results of the trial, or the subject's ability to participate in the trial.
  • Receipt within 1 month prior to Screening of any intraocular or periocular surgery (including refractive surgery), or an IVT injection or planned intraocular surgery or procedure during the course of the trial.
  • Current treatment or treatment within the past 12 months with therapies known to influence the immune system (including but not limited to cytostatics, interferons, TNF-binding proteins, drugs acting on immunophilins, or antibodies with known impact on the immune system).
  • Current treatment or treatment within the past 3 months or planned treatment with drugs known to be toxic to the lens, retina, or the optic nerve.
  • Use of any investigational drug or device within 3 months or 5 half-lives of Day 1, whichever is longer, or plans to participate in another study of a drug or device during the trial period.
  • Any prior receipt of genetic or stem-cell therapy for ocular or non-ocular disease.

5. Study Description

Brief Summary
PQ-110-005 (BRIGHTEN) is an open-label, dose escalation and double-masked, randomized, controlled study evaluating safety and tolerability of sepofarsen administered via intravitreal (IVT) injection in pediatric subjects (<8 years of age) with LCA10 due to the c.2991+1655A>G mutation over 24 months of treatment.
Detailed Description
This is an open-label, dose escalation and double-masked, randomized, controlled study evaluating safety and tolerability of sepofarsen administered via intravitreal (IVT) injection in pediatric subjects (<8 years of age) with LCA10 due to the c.2991+1655A>G mutation. The study consists of two parts: an open-label dose escalation part, followed by a double-masked randomized part. In the open label part; subjects will be assigned to one of 3 planned dose groups using a staggered dose escalation design. After at least 1 patient is dosed in each group; the Data Monitoring Committee (DMC) will review at least 4 weeks of safety data post dosing; and may recommend initiation of the next dose group. The DMC may recommend initiation of the double-masked randomized part of the study after completion of the last dose group in the dose escalation part of the study. In the double-masked, randomized, controlled part of the study; subjects will be randomized to one of 2 planned dose groups . Subjects will receive a unilateral IVT injection of sepofarsen on Day 1. Thereafter a 6-monthly dosing schedule is planned. After each dosing subjects will be assessed for safety and tolerability at follow up visits.
