An Expanded Access Program for Retinitis Pigmentosa in Adults Aged 18 Years and Older

This intermediate-size patient population expanded access program is to provide access to investigational product OCU400 for up to 75 patients with Retinitis Pigmentosa (RP) outside of the ongoing clinical trial Phase 3 program for patients who do not have access to alternative Food and Drug Administration (FDA)-approved products for treatment of the disease.

  3. Previous treatment with a gene-therapy or cell therapy product, excluding OCU400.
  4. Previous treatment with any investigational drug or device within one year, excluding OCU400.
