Active clinical trials for "Hematologic Neoplasms"

Allogeneic hematopoietic stem cell transplantation is a life-saving procedure in patients with blood cancers. Cord blood (CB) represents an alternative source of stem cells, which is associated with a lower risk of relapse, especially in the presence of minimal residual disease in the setting of acute leukemia and myelodysplasia. Furthermore, CB has the added advantage of being associated with a low risk of chronic graft versus host disease (GVHD). Unfortunately, CB transplants are hampered by a higher risk of transplant related mortality (TRM) when compared to bone marrow/peripheral blood transplants because of the limited cell dose of CB. In the previous UM171 trial (NCT02668315), the CB expansion protocol using the ECT-001-CB technology (UM171 molecule) has proven to be technically feasible and safe. UM171 expanded CB was associated with a median neutrophil recovery at day (D)+18 post transplant. Amongst 22 patients who received a single UM171 CB transplant with a median follow-up of 18 months, risk of TRM (5%) and grade 3-4 acute GVHD (10%) were low. There was no moderate-severe chronic GVHD. Thus, overall and progression free survival at 12 months were impressive at 90% and 74%, respectively. The UM171 expansion protocol allowed access to smaller, better HLA matched CBs as >80% of patients received a 6-7/8 HLA matched CB. Interestingly there were 5 patients who had already failed an allogeneic transplant and 5 patients with refractory/relapsed acute leukemia/aggressive lymphoma. Despite this high risk population, progression was 20% at 12 months. Hence, in this new trial, investigators are targeting patients with high and very high-risk acute leukemia/myelodysplasia to test the antileukemia effect of this new graft, a UM171 expanded CB.

The investigators propose an early phase study defined as a phase I/II trial assessing safety, feasibility and efficacy of CLIC-1901 autologous anti-CD19 Chimeric Antigen Receptor T cells (CAR-T) cells for participants with relapsed/refractory CD19 positive (CD19+) Acute Lymphoblastic Leukemia (ALL) and non-Hodgkin's Lymphoma (NHL). The Initial Stage of the study (n=20 participants) will focus on feasibility and safety while the Extended Stage will include all participants enrolled in the study (n=additional 40 participants for a total of 60) and will focus on efficacy and safety outcomes. In the proposed trial, we will administer our CAR-T cell product to these participants as a single infusion. Participants will undergo (a) lymphodepletion with cyclophosphamide and fludarabine, followed by (b) infusion of autologous CLIC-1901 CAR-T cells. All treatments will be delivered intravenously.

This is a Phase 1, nonrandomized, open-label, single-dose, dose-escalation, and dose-expansion study to evaluate the safety and clinical activity of PBCAR19B in adult study participants with CD-19 expressing malignancies.

This phase II trial studies how well a donor stem cell transplant, treosulfan, fludarabine, and total-body irradiation work in treating patients with blood cancers (hematological malignancies). Giving chemotherapy and total-body irradiation before a donor stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient, they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. The donated stem cells may also replace the patient's immune cells and help destroy any remaining cancer cells.

This single arm pilot phase I study with safety run-in is designed to estimate the safety and efficacy of a familial mismatched or haploidentical hematopoietic stem cell transplantation (haplo-HSCT) using a novel graft modification technique (selective αβ-TCR and CD19 depletion).

This is an open-label, two-part Phase 2 study investigating CGT9486 for the treatment of patients with Advanced Systemic Mastocytosis (AdvSM), including patients with Aggressive SM (ASM), SM with Associated Hematologic Neoplasm (SM-AHN), and Mast Cell Leukemia (MCL).

Reduced intensity conditioning (RIC) has been increasingly adopted as a modality to allow preparative conditioning pre-transplant to be tolerated by older adults or those patients that are otherwise unfit for myeloablative conditioning. In this study Reduced intensity conditioning (RIC) conditioning is used and followed by match aploidentical donor peripheral blood stem cell transplantation.

This study will find the maximum tolerated dose or the maximum planned dose of CYNK-001 which contains natural killer (NK) cells derived from human placental CD34+ cells and culture-expanded. CYNK-001 cells will be given after lymphodepleting chemotherapy. The safety of this treatment will be evaluated, and researchers want to learn if NK cells will help in treating acute myeloid leukemia.

This study investigates the infusion safety and potential curative properties of ex-vivo expanded γδ T cells obtained from the same donor for patients who have hematological malignancies and have accepted allogeneic hematopoietic stem cell transplantation.
