英文摘要
Autologous TGFB1 Modified CD34+ Stem Cells for Repair of Diabetic Macular Edema and Macular Ischemia
Retinal vascular diseases, such as diabetic macular edema and macular ischemia remain a common cause of vision
loss and blindness. Diabetes can damage the small blood vessels in the retina causing them to leak and occlude
resulting in vision loss. Although treatments are available for aspects of diabetic ocular disease no therapy is available
to treat the damaged retinal vasculature and ischemic retina. Vision loss from retinal ischemia can be irreversible. A
subgroup of DR patients suffers from macular ischemia and currently there is also no effective therapy. Research
over the last decade has identified a class of bone marrow‐derived circulating cells, CD34+ stem cells, which are
capable of homing to vascular lesions and facilitating vascular repair. However, many diabetic patients have
dysfunctional CD34+ stem cells with no reparative potential. In this SBIR Fast Track phase l/ll proposal we use a novel
strategy to correct dysfunctional diabetic CD34+ cells by transiently modifying CD34+ stem cells derived from patient
blood that both restores perfusion to the ischemic retina and correct vessel leaking. Experiments from our NIH
funded studies show that this CD34+ dysfunction can be corrected by transiently inhibiting endogenous transforming
growth factor‐β 1 (TGF‐β1) within the patient's own dysfunctional CD34+ stem cells using antisense
phosphorodiamidate morpholino oligomers (TGFβ1 PMO) to TGFβ1. Our proposed studies are focused according to
guidance of the FDA. In 2012 we completed a pre‐IND meeting with the FDA. A major goal is to complete an IND in
order to begin a first‐in‐man clinical trial. Our concern in developing this autologous stem cell approach is the safety
of the patient and the efficacy of the therapy. We have proposed 5 in vitro phase l CD34+ studies and 5 phase ll in
vivo studies (including Akimba mice and diabetic baboons), testing safety and efficacy of our therapy. The
investigators of this application include a very experienced CEO, a well‐known practicing/research ophthalmologist,
an international known PMO expert and a CD34+ stem cell biologist.
