Application Title:

Autologous Gene Corrected Sinus Basal Cells to Treat Serious Cystic Fibrosis Sinus Disease

Public Abstract:
Therapeutic Candidate or Device

Gene corrected autologous sinus airway basal stem cells from patients with Cystic Fibrosis.

Indication

The proposed studies provide an innovative stem cell based approach with gene correction to treat chronic sinusitis in CF.

Therapeutic Mechanism

Corrected upper airway cells will produce differentiated epithelium with restored Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene function. This restored function will enable improved muco-ciliary clearance which will resolve chronic sinusitis in CF patients and dramatically improve quality of life.

Unmet Medical Need

Small molecule modulators for CF cannot treat all patients. Previous attempts using viral and non-viral gene therapies have been unsuccessful. CRISPR/Cas9 genome editing enabling the precise correction of CF causing mutations in airway stem cells offers a durable autologous cell therapy to treat CF.

Project Objective

Filing of IND application with the FDA

Major Proposed Activities

  • Develop process for Patient Scale Manufacturing Runs and complete three runs that meet release specifications
  • Completion of nonclinical feasibility, safety and biodistribution studies
  • Submit clinical protocol to IRB and file an IND with the FDA
Statement of Benefit to California:
Cystic Fibrosis (CF) is one of the most common genetic diseases in California. There is no curative therapy for CF and CF patients spend a lifetime focused on mitigating the symptoms of their disease. Moreover, the costs of treating a single CF patient are enormous. Thus, the benefit to California if this proposal is successful is that it would improve the lives of its citizens (both patients and family members) while simultaneously decreasing the societal costs associated with this disease.
