Objectives

Narrative objectives1

Retinitis pigmentosa (RP) is an inherited retinal degenerative disease for which no effective treatment has yet been established. We have developed a simian immunodeficiency virus from African green monkey (SIVagm) vector carrying the human pigment epithelium-derived factor (PEDF) gene (SIV-hPEDF, DVC1-0401) that exhibits potent neuroprotective effects. The "Phase I/IIa investigator-initiated clinical trial of DVC1-0401 subretinal administration of neuroprotective gene therapy for retinitis pigmentosa" started in February 2019, with a one-year post-administration observation period. The trial is now underway with a one-year observation period after administration. In order to investigate the long-term safety and efficacy of this vector, this clinical study will continue the observation period after the completion of the clinical trial.
