Efficacy and safety of cryopreserved autologous CD34+ HSC transduced with EFS lentiviral vector encoding for human ADA gene in ADA-SCID subjects
Therapeutic Candidate or Device Autologous CD34+ hematopoietic stem cells (HSCs) transduced with a lentiviral vector encoding the human ADA gene (or "OTL-101") Indication Adenosine Deaminase – Severe Combined Immunodeficiency (or ADA-SCID) Therapeutic Mechanism This project will lead to a License Application for OTL-101 as a treatment for ADA-SCID. The patient’s own stem cells ("autologous") are […]
In Utero Hematopoietic Stem Cell Transplantation For The Treatment Of Fetuses With Alpha Thalassemia Major
Therapeutic Candidate or Device Maternal bone marrow-derived CD34+ hematopoietic stem cells. Indication Fetal alpha thalassemia major. Therapeutic Mechanism This strategy that takes advantage of existing tolerance between the mother and fetus during pregnancy, so that maternal cells can be transplanted into a fetus without conditioning or immunosuppression. Survivors of alpha thalassemia need chronic blood transfusions […]
A Phase I/II, Non Randomized, Multicenter, Open-Label Study of G1XCGD (Lentiviral Vector Transduced CD34+ Cells) in Patients With X-Linked Chronic Granulomatous Disease
Therapeutic Candidate or Device The therapeutic product candidate is autologous CD34+ hematopoietic stem/progenitor cells (HSPC) transduced with the G1XCGD lentiviral vector. Indication The target indication is for the transplantation of patients with severe X-linked Chronic Granulomatous Disease (XCGD) lacking matched donors. Therapeutic Mechanism Transplantation and engraftment of gene-corrected autologous HSPC after reduced intensity conditioning for […]
TRX103 for prevention of GvHD in patients receiving HLA mismatched related or unrelated allogeneic HSCT for the treatment of hematologic malignancies.
Therapeutic Candidate or Device An allogenic, off the shelf, engineered regulatory T cell product that mimics the function of T regulatory Type 1 (Tr1) cells. Indication Prevention of acute and chronic Graft versus Host Disease (GvHD) in patients undergoing mismatched stem cell transplant. Therapeutic Mechanism GvHD is driven by the reaction of allogenic donor T […]
Hematopoietic Stem Cell Gene Therapy for XCGD
Therapeutic Candidate or Device Hematopoietic stem and progenitor cells collected from X-CGD patients modified with a highly regulated lentiviral vector Indication X-linked Chronic Granulomatous Disease Therapeutic Mechanism Lentiviral vector (LV) modification of autologous hematopoietic stem and progenitor cells (HSPCs) to restore physiologic gp91phox expression. We have developed a next-generation LV designed by bioinformatic-guided screening of […]
IND-enabling activities for a Phase 1 Study of Autologous CD4LVFOXP3 T Cells in Subjects with IPEX Syndrome
Therapeutic Candidate or Device CD4+ T cells that have undergone lentiviral -mediated gene transfer of Forkhead Box P3 (FOXP3) and acquired regulatory T cell function. Indication Immune dysregulation Polyendocrinopathy Enteropathy X-linked (IPEX) syndrome Therapeutic Mechanism Administration of autologous CD4LVFOXP3 that constitutively and stably express wild-type FOXP3 gene will replace the lack of functional regulatory T […]
Curing Sickle cell Disease with CRISPR-Cas9 genome editing
Therapeutic Candidate or Device Blood stem cells collected from individuals with sickle cell disease will have the sickle gene corrected and then given back to the same individual. Indication Sickle cell disease is a hereditary blood disorder associated with pain and other serious medical complications including a shortened life-span Therapeutic Mechanism It is possible to […]
Genome Editing of Autologous Hematopoietic Stem Cells to Treat Sickle Cell Disease
Therapeutic Candidate or Device Autologous blood stem cells edited to correct the sickle cell disease mutation to be given back to the patient as an autologous stem cell transplant Indication Severe sickle cell disease Therapeutic Mechanism The mechanism of the proposed therapy for sickle cell disease is that the genetically engineered autologous HSCs (pathologic S […]
Ex Vivo Transduction of the Human Artemis (DCLRE1C) cDNA by Lentiviral Vector AProArt into CD34+ Hematopoietic Cells for Artemis (ART)-Deficient Severe Combined Immunodeficiency (SCID)
Therapeutic Candidate or Device Blood-forming stem cells harboring a SCID gene defect, modified to become normal by addition of a correct copy of the Artemis/DCLRE1C DNA repair gene. Indication Treatment of severe combined immunodeficiency due to defects in the Artemis/DCLRE1C gene. Therapeutic Mechanism Severe combined immunodeficiency (SCID) is characterized by absence of T and B […]
Pre-clinical development of gene correction therapy of hematopoietic stem cells for SCID-X1
Severe combined immunodeficiency caused by mutations in the IL2RG gene on the x-chromosome (SCID-X1 or “bubble boy disease”) is a devastating genetic disease that results in boys not being able to form an immune system. If they are exposed to the environment for even a short period of time they can get infections that a […]
