What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]
Incidence of ocular and non-ocular adverse events (AEs) and serious adverse events (SAEs) following LX107 subretinal injection
Measured: 6 Months
Secondary outcomes (5)
Changes in Functional Magnetic Resonance Imaging (fMRI) Results
Measured: 6 months、12 months
Mean Change from Baseline in Multi-luminance Mobility Test (MLMT)
Assess the subject's mobility ability under different light intensities using MLMT, and compare the mean changes from baseline at 180 and 365 days after treatment to reflect improvements in visual function.
Measured: 6 months、12 months
Mean Change from Baseline in Full-Field Sensitivity Threshold (FST)
Measure the subject's light perception ability using FST, and compare the mean changes from baseline at 180 and 365 days after treatment to evaluate improvements in visual sensitivity.
Measured: 6 months、12 months
Mean Change from Baseline in Visual Acuity (VA)
Measure VA using ETDRS and BRVT charts, with LogMAR score as the indicator, and compare the mean changes from baseline at 180 and 365 days after treatment to assess visual acuity improvement.
Measured: 6 months、12 months
Mean Change from Baseline in Visual Fields
Use Goldmann perimeter (dynamic visual field) and Humphrey perimeter (static visual field) to compare the mean changes from baseline at 180 and 365 days after treatment, evaluating improvements in visual field range and sensitivity.
Measured: 6 months、12 months

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing LX107 Injection in people with Retinal Dystrophy, run by Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 19 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 10 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] (time frame: 6 Months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Mar 2026.
