Clinical Trial Summary

This study will evaluate safety, tolerability, and preliminary efficacy of a single intravitreal (IVT) injection of a recombinant adeno-associated virus (AAV) gene therapy, 4D-110, in male patients with genetically-confirmed Choroideremia (CHM).

Description:

This is an open-label, Phase 1 study to evaluate safety and tolerability as well as preliminary efficacy of a single IVT injection of 4D-110 at three dose levels in male patients with genetically-confirmed CHM.

Eligibility

Key Inclusion Criteria:

• Diagnosis of CHM defined as a pathogenic mutation in the CHM gene, confirmed by genetic testing
• Both eyes must have = 34 ETDRS letters (~20/200)

Key Exclusion Criteria:

• Clinically significant, active ocular or peri-ocular infection or inflammation in the study eye
• Patient has previously received any AAV treatment
• Ocular conditions or ocular media opacity in either eye that would preclude the planned treatment (i.e. IVT injection) or interfere with the interpretation of study endpoints (e.g. significant lens opacity)

Related Conditions & MeSH terms

Intervention

Biological:
• 4D-110
4D-110 drug product developed for gene therapy which comprises an AAV capsid variant (4D-R100) carrying a transgene encoding a codon-optimized human CHM gene.
