Active clinical trials for "Hematologic Diseases"

This is a single-arm, open-label, single-center, phase I study. The primary objective is to evaluate the safety of CD7 CAR-T therapy for patients with CD7-positive relapsed or refractory T-ALL/LBL, and to evaluate the pharmacokinetics of CD7 CAR-T in patients.

This is a single-arm, open-label, single-center, phase I study. The primary objective is to evaluate the safety of CD7 CAR-T Bridging to allo-HSCT therapy for patients with CD7-positive relapsed or refractory Malignant Hematologic Diseases

This is a phase 1/2, open-label study designed to assess the safety and clinical activity of different belantamab mafodotin doses in combination with lenalidomide, dexamethasone and nirogacestat in patients with transplant ineligible newly diagnosed multiple myeloma. This will be a 2-part study. In part 1 participants will be enrolled in one cohort to receive belantamab mafodotin in combination with lenalidomide, dexamethasone and nirogacestat and will determine the recommended phase 2 dose (RP2D) to be further evaluated for safety and clinical activity in the dose expansion cohort. The RP2D dose will be used in future studies in the transplant-ineligible newly diagnosed multiple myeloma (NDMM) setting. In the dose expansion phase (Part 2) an expansion cohort will be treated with the RP2D. The expansion cohort will randomize participants (1:1) in two groups to evaluate two alternate dose modification guidelines for corneal AEs. Part 2 of the study will also evaluate an alternative dose modification guideline for corneal adverse events (AEs). Overall, approximately 36 participants will be enrolled in the study. Participant follow-up will continue up to 3 years after the last participant is enrolled (follow-up period range: 3-4 years). The estimated accrual period will be 12 months, corresponding to an approximate total study duration of 4 years.

This is a single-arm, open-label, single-center, phase I study. The primary objective is to evaluate the safety of CD7 Chimeric Antigen Receptor-T(CAR-T) therapy for patients with CD7-positive relapsed or refractory T-Acute Lymphoblastic Leukemia(ALL)/Lymphoblastic Lymphoma(LBL)/Acute Myelogenous Leukemia(AML), and to evaluate the pharmacokinetics of CD7 CAR-T in patients。

This is a single-arm, open-label, single-center, phase I study. The primary objective is to evaluate the safety of CD7 CAR-T therapy for patients with CD7-positive relapsed or refractory T-ALL/LBL, and to evaluate the pharmacokinetics of CD7 CAR-T in patients.

This is a single-dose, open-label study in pediatric participants with severe SCD and hydroxyurea (HU) failure or intolerance. The study will evaluate the safety and efficacy of autologous CRISPR-Cas9 modified CD34+ human hematopoietic stem and progenitor cells (hHSPCs) (CTX001).

This study is a single-center, treatment protocol with 4 possible preparative regimens, designed to validate the process of umbilical cord blood stem cell transplantation at our institution.

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 research is being done to learn if a new type of haploidentical transplantation using TCR alpha beta and CD19 depleted stem cell graft from the donor is safe and effective to treat the patient's underlying condition. This study will use stem cells obtained via peripheral blood or bone marrow from parent or other half-matched family member donor. These will be processed through a special device called CliniMACS, which is considered investigational.

For several decades, allogeneic hematopoietic stem cell trans-plantation (allo-HSCT) has remained an important strategy in the management of patients with high-risk hematological malignancies. The acceptance of umbilical cord blood (UCBT) and haploidentical grafts (Haplo) as viable alternative donors for allo-HSCT has increased the options for patients with no matched donors and now ensures that a donor can be identified for virtually all patients. Relapsed disease is a principal threat to these patients and affects 30-50% of them. The therapeutic options for these relapsing patients are diverse but remain largely ineffective in altering their long-term outcomes. Therefore, pre-emptive treatment post allo-HSCT is considered. MHC (major histocompatibility complex) class II molecules are a family of molecules normally found only on hematopoietic cells. cell-surface proteins are responsible for the regulation of the immune system in humans and are important in disease defense. They are the major cause of organ transplant rejections. Different HLA-DPB1 alleles exist in the general population. HLA-DPB1*04:01 is the most frequent (70.5%) while HLA-DPB1*02:01 represents 32% and HLA-DPB1*03:01 20%. In allo-HSCT, the donor and the recipient may express different HLA-DPB1 molecules. HLA-DPB1 matching status has an impact on GVL (graft versus leukemia) and GVHD. In recipients of HSCT, a match for DPB1 is associated with a significantly increased risk of disease relapse, irrespective of the matching status of other HLA molecules.. Therefore, one could anticipate that a mismatched of HLA class II could induce a selective GVL reactivity without GVHD. HLA-DP-expressing B cell and myeloid malignancies can be recognized and lysed by HLA-DP-specific T cells. The majority of leukemic cells (Acute Myeloid Leukemia, Acute Lymphoid Leukemia, Chronic Lymphoid Leukemia) express HLA-DP. A T cell clone recognizing specifically HLA-DPB1*0401 has been developed as a permanent cell line This clone has been demonstrated to be able to kill HLA-DPB1*0401 positive leukemic cells. In addition, this clone harbors a special suicide gene allowing the destruction of the clone in presence of a specific anti-viral drug named ganciclovir. We hypothesize that infusion of a third party suicide gene-transduced T cell clone directed against HLA-DPB1*401 might protect against possible relapse of hematological malignancies. We propose to inject iv escalating dose of a third party clone recognizing HLA-DPB1*04:01, 4 to 5 months following transplantation (when immunosuppressive drugs have been discontinued) in patients HLA-DPB1*04:01 positive with a donor HLA-DPB1*04:01 negative to evaluate the feasibility, toxicity, benefits of this immune intervention.
