Official title:
An Open-Label, Dose Escalation and Double-Masked, Randomized, Controlled Study to Evaluate the Safety and Tolerability of Sepofarsen in Pediatric Subjects <8 Years of Age With Leber Congenital Amaurosis Type 10 (LCA10) Due to the c.2991 +1655A>G (p.Cys998X) Mutation.

Clinical Trial 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.

Clinical Trial 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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
