Trial Outcomes & Findings for Efficacy & Safety Study of Bilateral IVT Injection of GS010 in LHON Subjects Due to the ND4 Mutation for up to 1 Year (NCT NCT03293524)

NCT ID: NCT03293524

Last Updated: 2026-04-16

Results Overview

The primary efficacy endpoint was the change from baseline of BCVA reported with LogMAR at 1.5-year post-treatment, in the second-affected/not-yet-affected eyes of ND4 LHON patients with vision loss up to one year. LogMAR BCVA was used to represent BCVA.

Participant Flow

108 patients (≥ 15 years old) were screened for eligibility in 13 sites (Belgium, France, Italy, Spain, Taiwan, United Kingdom: 1 site each, and the United States: 7 sites). Of these, 98 were randomized: 48 to treatment Arm 1 (GS010-GS010) and 50 to treatment Arm 2 (GS010-placebo). The remaining 10 participants were screen failures.

108 patients with the G11778A mitochondrial point mutation in the ND4 gene and vision loss of up to 1 year in one or both eyes were screened. Screening failures (10) including patients who did not meet inclusion criteria or met exclusion criteria.

GS010-GS010
All study participants received single IVT injection of GS010 in their first-affected eye (droplet digital polymerase chain reaction \[ddPCR\] dose of 1.2/1.3E11 vg in 90 μL). Participants randomized to this treatment arm received a single IVT injection of GS010 in their second-affected/not-yet-affected eye at a ddPCR dose of 1.2/1.3E11 vg in 90 μL. Treatment could be performed either on a single day (1 IVT injection in each eye on Day 0) or on 2 consecutive days (1st IVT injection on Day -1 and 2nd IVT injection on Day 0).
GS010-Placebo
All study participants received single IVT injection of GS010 in their first-affected eye (droplet digital polymerase chain reaction \[ddPCR\] dose of 1.2/1.3E11 vg in 90 μL). Participants randomized to this treatment arm received placebo IVT injection (volume of 90 μL) in their second-affected/not-yet-affected eye. Treatment could be performed either on a single day (1 IVT injection in each eye on Day 0) or on 2 consecutive days (1st IVT injection on Day -1 and 2nd IVT injection on Day 0).

Timeframe: From baseline to 5 years post-treatment

Population: The intent-to-treat analysis (ITT) population consisted of all randomized subjects. The analyses were based on the planned treatment (as randomized). Participants in the ITT population without a Year 5 assessment were not included in the analysis.

Change from baseline to 5 years follow up in the Visual Function Questionnaire (VFQ-25) composite score. The VFQ-25 is a patient-reported outcome instrument assessing vision-related quality of life and consists of a base set of 25 vision-targeted questions representing 11 vision-related constructs plus an additional single-item general health rating question. Each item was converted to a 0-100 scale for scoring, where 100 represents the best possible score on the measure and 0 represents the worst. Items within each subscale were averaged to create 12 subscale scores (11 subscales related to vision + 1 subscale related to general health). The vision-related subscale scores (excluding the general health rating question) were then averaged to calculate the composite score.

Measure
GS010-GS010
n=49 participants at risk
All study participants received single IVT injection of GS010 in their first-affected eye (ddPCR dose of 1.2/1.3E11 vg in 90 μL). Participants randomized to this treatment arm received a single IVT injection of GS010 in their second-affected/not-yet-affected eye at a ddPCR dose of 1.2/1.3E11 vg in 90 μL. Treatment could be performed either on a single day (1 IVT injection in each eye on Day 0) or on 2 consecutive days (1st IVT injection on Day -1 and 2nd IVT injection on Day 0).
GS010-Placebo
n=49 participants at risk
All study participants received single IVT injection of GS010 in their first-affected eye (ddPCR dose of 1.2/1.3E11 vg in 90 μL). Participants randomized to this treatment arm received placebo IVT injection (volume of 90 μL) in their second-affected/not-yet-affected eye. Treatment could be performed either on a single day (1 IVT injection in each eye on Day 0) or on 2 consecutive days (1st IVT injection on Day -1 and 2nd IVT injection on Day 0).
