Grant Award Details
Conduct a first in human clinical trial to assess safety and efficacy of subretinal injection of human neural progenitor cells for the treatment of retinitis pigmentosa.
Grant Application Details
- Clinical Study to Assess Safety and Efficacy of Subretinal Injection of Human Neural Progenitor Cells for Treatment of Retinitis Pigmentosa
Therapeutic Candidate or Device
CNS10-NPC - a human neural progenitor cell line
1. Phagocytosis of photoreceptor outer segment debris.
2. The release of pro-survival factors that have localized diffusion to inhibit retinal photoreceptor cell death.
3. Immunomodulation resulting in markedly fewer host inflammatory cells at the site of CNS10-NPC engraftment
Unmet Medical Need
Retinitis pigmentosa represents an unmet clinical need in ophthalmology. Despite growing understanding of the underlying molecular mechanisms, there remains little in the way of available treatment.
Phase 1/2a Completed
Major Proposed Activities
- Assess clinical safety of the clinical product (CNS10-NPC)
- Obtain clinical data based on secondary outcome measures of vision loss
- Manufacture additional clinical product for a subsequent Phase 2 trial
There are over 10,000 retinitis pigmentosa patients in CA who could benefit from this type of stem cell treatment. The information gained through this trial will also advance the field of cell therapy for this disease. While gene therapy is a promising approach for patients with specific mutations, cell-based therapies have the potential to be applicable to all retinitis pigmentosa patients regardless of genotype. If successful, this therapy could also benefit patients with macular degeneration.
