Organ function indications and potential improvements following curative therapy for sickle cell disease
Hematology Am Soc Hematol Educ Program. 2022 Dec 9;2022(1):277-282. doi: 10.1182/hematology.2022000372.ABSTRACTCurative therapies for sickle cell disease include allogeneic hematopoietic stem cell transplantation (HSCT) and gene-modified autologous stem cell transplantation. HSCT has been used for 30 years with success measured by engraftment, symptom control, graft-vs-host disease (GVHD) risk, organ toxicity, and immune reconstitution. While human leukocyte antigen-matched sibling donor (MSD) transplants have excellent outcomes, alternate donor transplants (unrelated/haploidentical) are just beginning to overcome GVHD and...

Comparison of vascular growth factors in the murine brain reveals placenta growth factor as prime candidate for CNS revascularization
Vascular bypass procedures in the central nervous system (CNS) remain technically challenging, hindered by complications and often failing to prevent adverse outcome such as stroke. Thus, there is an unmet clinical need for a safe and effective CNS revascularization. Vascular endothelial growth factors (VEGFs) are promising candidates for revascularization; however, their effects appear to be tissue-specific and their potential in the CNS has not been fully explored. To test growth factors for angiogenesis in the CNS, we characterized the effects of endothelium-specific growth factors on the brain vasculature and parenchym...

Inflammation in sickle cell disease.
Abstract The primary β-globin gene mutation that causes sickle cell disease (SCD) has significant pathophysiological consequences that result in hemolytic events and the induction of the inflammatory processes that ultimately lead to vaso-occlusion. In addition to their role in the initiation of the acute painful vaso-occlusive episodes that are characteristic of SCD, inflammatory processes are also key components of many of the complications of the disease including autosplenectomy, acute chest syndrome, pulmonary hypertension, leg ulcers, nephropathy and stroke. We, herein, discuss the events that trigger infla...

Current Results of Lentiglobin Gene Therapy in Patients with Severe Sickle Cell Disease Treated Under a Refined Protocol in the Phase 1 Hgb-206 Study
Backgroundβ-globin gene transfer has the potential for substantial clinical benefit in patients with sickle cell disease (SCD). LentiGlobin Drug Product (DP) contains autologous CD34+ hematopoietic stem cells (HSCs) transduced with the BB305 lentiviral vector (LVV), encoding β-globin with an anti-sickling substitution (T87Q). The safety and efficacy of LentiGlobin gene therapy is being evaluated in the ongoing Phase 1 HGB-206 study (NCT02140554). Results in the initial 7 patients treated with LentiGlobin DP from steady state bone marrow harvested (BMH) HSCs using original DP manufacturing process (Group A) demons...

Efficacy Evaluation of Liver-Directed Gene Therapy in Fabry Mice
Conclusions: Collectively, these data provide strong evidence that our liver-directed AAV-mediated gene therapy approach holds considerable therapeutic potential for the treatment of Fabry disease. We anticipate that a single dose IV procedure will pose minimal burden to Fabry patients and will be a viable alternative to biweekly enzyme infusions, potentially reducing treatment-related morbidity whislt improving patient quality of life and potentially providing them with a functional long-term cure.DisclosuresKia: Freeline: Employment, Equity Ownership.
