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.
