中文摘要
自体TGFB1修饰的CD34+干细胞用于糖尿病黄斑水肿和黄斑缺血的修复。
--
视网膜和血管疾病,如糖尿病、黄斑水肿和黄斑缺血,仍然是视力障碍的常见原因。
失明和失明。糖尿病可以使视网膜周围的小血管受损,导致血管渗漏和闭塞。
导致视力丧失。尽管有多种治疗方法可用于治疗糖尿病眼病的各个方面,但目前还没有有效的治疗方法。
为了更好地治疗视网膜血管系统受损和视网膜缺血,视网膜缺血造成的视力损失是不可逆转的。
研究发现,患有黄斑缺血的患者中,有一小部分人患有黄斑缺血,目前也没有有效的治疗方法。
在过去的十年里,人们已经发现了一种新的骨髓来源的循环干细胞,即CD34+干细胞,其中包括。
有能力找到并修复血管病变,并促进血管修复。然而,许多糖尿病患者已经患有糖尿病。
功能失调的CD34+骨髓干细胞没有任何修复的潜力。在这篇文章中,我们可以用一种新的方式来描述SBIR和快速通道第二阶段的L。
纠正功能障碍的糖尿病患者CD34+干细胞的策略是通过暂时改变从患者体内提取的CD34+干细胞。
这种血液既能恢复血液灌流,防止视网膜缺血,又能纠正血管渗漏。我们的实验来自美国国立卫生研究院。
资助的研究表明,这种CD34+细胞功能障碍可以通过暂时抑制内源性细胞转化来纠正。
生长因子-转化生长因子-1(Growth-CD34-1,β-1)在患者自身功能障碍的CD34+干细胞内,使用反义核酸。
据报道,转化生长因子β1和吗啡低聚物(转化生长因子β1)是我们目前提出的研究重点。
美国食品和药物管理局的指导意见。2012年9月,我们完成了与美国食品和药物管理局的一次主要的IND前会议。我们希望在2012年完成一次IND前的会议。
为了开始一项首个人的临床试验。我们最关心的是开发这种自体干细胞移植方法的安全性。
我们已经提出了L的体外试验阶段的第5个阶段,CD34+细胞的研究阶段和第5个阶段的临床研究。
Vivo研究了我们的治疗方法的安全性和有效性,包括对Akimba小鼠和糖尿病患者的研究。
这一申请的调查人员包括一位非常有经验的首席执行官,一位著名的执业/研究眼科医生。
一位著名的国际专家是PMO的专家,也是一位CD34+的干细胞和生物学家。
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.
