简要总结
Allogeneic Stem Cell Transplantation of NiCord®, Umbilical Cord Blood-Derived Ex Vivo Expanded Stem and Progenitor Cells, in Patients with Hemoglobinopathies
详细描述
Umbilical cord blood (UCB) is an alternative stem cell source for hematopoietic stem cell transplantations (HSCT) and can be used for the treatment of various life-threatening diseases, such as hematological malignancies or genetic blood disorders, in such cases where a matched related stem cell donor is not available. However, the major drawback of using this valuable stem cells source is the limited cell dose in a single cord blood unit (CBU), which was shown to be associated with inadequate hematopoietic reconstitution and high risk of transplant-related mortality. To improve outcomes and extend applicability of UCB transplantation, one potential solution is ex vivo expansion of UCB-derived stem and progenitor cells. NiCord® is a stem/progenitor cell based product composed of ex vivo expanded allogeneic UCB cells. NiCord® is based on a novel technology for the ex vivo cell expansion of cord blood derived hematopoietic progenitor cells. By increasing the number of the short and long-term reconstitution progenitor cells transplanted, NiCord® has the potential to enable the broader application of UCB transplantation, and improve the clinical outcomes of UCB transplantation.
In Part 1 of this study, NiCord® will be administered to the patient in conjunction with a second, unmanipulated CBU. In Part 2 of this study, NiCord® will be administered to the patient without a second, unmanipulated CBU. The study duration per patient is approximately 270 days from signing of informed consent to last visit on day 180 post-transplant.
The overall study objectives of part 1 of this study are to evaluate the safety and efficacy of co-transplantation of NiCord® and an unmanipulated CBU in patients with Hemoglobinopathies (Sickle Cell Disease (SCD), or thalassemia major) following myeloablative therapy. The overall study objectives of part 2 of this study are to evaluate the safety and efficacy of transplantation of NiCord® in patients with Hemoglobinopathies (Sickle Cell Disease (SCD), or thalassemia major) following myeloablative therapy.
The study hypothesis for part 1 of this study is that the co-transplantation of NiCord® and an unmanipulated unrelated cord blood graft in patients with hemoglobinopathies (SCD, or thalassemia major) following myeloablative preparative therapy will be safe and will enable cord blood engraftment. The study hypothesis for part 2 of this study is that transplantation of NiCord® in patients with hemoglobinopathies (SCD, or thalassemia major) following myeloablative preparative therapy will be safe and will enable cord blood engraftment.
Up to fifteen (15) evaluable patients recruited for part 1 of the study and up to five (5) patients for part 2 of the study should be 2-45 years of age, at least 10 kg in weight, have symptomatic SCD or thalassemia major and should be considered as candidates for allogeneic myeloablative HSCT for the treatment of SCD.

研究组 & 干预措施
NiCord
NiCord: NiCord® is a cell-based product composed of umbilical cord-derived ex vivo expanded stem and progenitor cells.
干预措施: NiCord (Drug)
结局指标
主要结局
Safety and Tolerability Will be Measured by Acute NiCord® Infusional Toxicity.
时间窗: 24 hours post-infusion
Assessment of acute toxicity associated with the infusion of NiCord within 24 hours post-infusion.
Assessment of Cumulative Incidence of Donor-derived Neutrophil Engraftment.
时间窗: By Day 42
Neutrophil engraftment is defined as achieving an absolute neutrophil count (ANC) of ≥500/ μL for 3 consecutive measurements on different days by Day 42 inclusive (the day of engraftment was defined as the first of these 3 days).
次要结局
- Overall Survival(180 days)
- Proportion of Transplant-related Mortality.(at 100 days)
- Event-free Survival(100 days post-transplant)
