Further study details as provided by University of California, Davis:

Primary Outcome Measures:
  • Incidence and severity of ocular adverse events [ Time Frame: 1 day to 6 months ] [ Designated as safety issue: Yes ]
    As evident on eye examination by severe decrease in vision and/or adverse effect requiring major treatment intervention directly attributable to study treatment.

Secondary Outcome Measures:
  • The number of stem cells isolated and injected into the study eye [ Time Frame: 1 day ] [ Designated as safety issue: No ]
    Will determine the yield of the bone marrow aspiration and stem cell isolation procedures.

Other Outcome Measures:
  • Incidence and severity of systemic adverse events [ Time Frame: 1 day to 6 months ] [ Designated as safety issue: Yes ]
    Any systemic adverse event attributable to the bone marrow aspiration or intravitreal injection of the stem cells.

Estimated Enrollment: 15
Study Start Date: July 2012
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Stem cell treated Drug: CD34+ bone marrow stem cells intravitreal

Detailed Description:
In this pilot clinical trial, eyes with irreversible vision loss from retinal degenerative conditions (macular degeneration or retinitis pigmentosa) or retinal vascular disease (diabetic retinopathy or retinal vein occlusion) will be treated with intravitreal injection of autologous CD34+ stem cells isolated from bone marrow aspirate under Good Manufacturing Practice conditions. This study will determine whether there are any major safety and feasibility concerns using this therapy. Patients will be followed for 6 months after treatment by serial comprehensive eye examination supplemented with various retinal imaging and diagnostic tests.
