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.

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.
