This is an Investigator-Initiated, phase 2, prospective, open-label study designed to be conducted in six hospitals in Greece. Eligible patients will initially receive an induction phase of six 28-day cycles of isatuximab in combination with bortezomib, cyclophosphamide, and dexamethasone (VCd), followed by a maintenance phase with isatuximab and lenalidomide until disease progression, death, unacceptable adverse events, lost to follow up, or consent withdrawal, whichever occurs first. The study will last for approximately 36 months (follow-up period), starting from the date of the first patient in, to the date of the last patient last visit. The primary objective is to assess the effect of induction treatment with isatuximab in combination with VCd on the renal function of newly diagnosed patients with multiple myeloma and severe renal impairment (RI). The secondary objectives are to evaluate the effect of isatuximab in combination with VCd, followed by lenalidomide maintenance on: Overall response rate, Progression-Free Survival, Time to Response, Duration of Response, Overall Survival, Minimal Residual Disease negativity rate, Safety
Gas station workers are exposed to carcinogenic substances.This increases risk of their exposure to hematological diseases such as lymphoblastic leukemia (ALL), chronic lymphocytic leukemia (CLL), myelodysplastic syndromes (MDS), and myelogenous leukemia (AML), as well as different forms of non-Hodgkin's lymphoma (NHL) and multiple myeloma. Thus, the early identification of this condition between the gas station workers may prevent the hematological disease progression.
Prognosis of patients with graft failure is dismal, and re-transplantation is the sole option for long-term survival. Currently, there is no consensus concerning therapeutic options in patients with primary or secondary (within the 60 days post-transplantation) graft failure and finding a new donor within an acceptable delay is challenging. Literature is poor on the subject while the overall survival of such patients is about 30% at 1 year. This situation thus represents today a very challenging unmet medical need. Recently, haploidentical (haplo) related donor Stem Cell Transplantation (haplo-SCT) have improved dramatically outcomes using T-cell replete grafts with administration of post-transplantation cyclophosphamide (PTCy, which targets alloreactive T cells generated early after an HLA-mismatched transplant, sparing regulatory T cells and leaving unaffected the non-dividing hematopoietic stem cells) and standard post-transplant immune suppression with a calcineurin inhibitor (CNI) and mycophenolate mofetil. Our group re-transplanted a patient who experienced two consecutive graft failures and was successfully managed through a third haplo-SCT from her son using PTCy. We then retrospectively collected and analyzed data from 26 primary graft failure patients transplanted between 2011 and 2017 in 15 centers on behalf of French Society for Stem Cell Transplantation and Cell Therapy (SFGM-TC). The study population consisted mainly of patients with primary or secondary (within the 60 days post-transplantation) graft failure who underwent haplo-SCT and received PTCy as graft-versus-host-disease prophylaxis. The 1-year overall survival was about 60% suggesting that this approach might be a valid option in this particular poor clinical situation but now need validation through a phase II multicenter, national, prospective cohort study.
This single institution, phase I clinical trial will determine the safety and feasibility of employing T-cell receptor (TCR) αβ+ and CD19+ (Cluster of Differentiation ) depleted hematopoietic stem cell transplantation (HSCT) using peripheral blood stem cells (PBMC) from closely matched unrelated donors or haploidentical donors to treat non-malignant hematologic diseases in children and young adults. Allogeneic hematopoietic stem cell transplantation has become a curative option for children and adolescents with a variety of otherwise fatal conditions. To reduce the incidence and severity of graft-versus-host disease (GVHD) associated with allogeneic hematopoietic stem cell transplantation, donor grafts are depleted of T cells, either using CD34+ selection or CD3+/CD19+ depletion of grafts. However, these selection processes also deplete the graft of protective cell subsets, such as γδ T cells, natural killer(NK) cells, monocytes and dendritic cells, which play important roles in the immune response to infectious agents. Moreover, the presence of NK cells and γδ T in donor grafts is associated with more rapid immune reconstitution after HSCT transplantation. In order to retain these protective immune cell subsets, this trial will use a novel, highly selective graft engineering process using the Miltenyi CliniMACS system that selectively depletes αβ-T cells and B cells which are responsible for GVHD and Epstein Barr Virus (EBV)-related post-transplantation lymphoproliferative disorder, respectively. Prior to transplantation, patients will be treated with a conditioning regimen, specific for the original disorder. The primary objective of this study is evaluation of the safety and feasibility of HSCT using TCRαβ+/CD19+ depleted hematopoietic stem cells to treat non-malignant hematologic diseases. This will be assessed by evaluating the incidence of graft failure, grade III-IV acute GVHD and chronic GVHD and TRM. Secondary objectives include the evaluation of immune reconstitution and incidence of post-transplant infections, adverse events, serious adverse events, overall and disease-free survival and the efficiency of graft processing by the CliniMACS System.
Background: The National Heart, Lung, and Blood Institute (NHLBI) conducts clinical trials that look at new ways to prevent, detect, or treat disease. It wants to create an NHLBI Recruitment Registry that lets people sign up to be contacted for NHLBI studies. It also wants to make sure that the data people share about themselves is safely stored. Researchers will be able to use this registry to prescreen people for clinical trials. Objective: To create and maintain an NHLBI research participant recruitment registry. This is an observational registry for collecting, storing, and providing access to data on people with a disease or condition of interest, or as a healthy volunteer to the NHLBI. Eligibility: People who contact the NIH to participate in an NHLBI IRB-approved study Design: Researchers will contact participants by telephone to obtain informed consent verbally. Participants will give the following data: - name - date of birth - phone number - address - email address - diagnosis (if applicable) - referring provider. Participants will share how they heard of the study. They may give their medical records. They may be asked if they were enrolled in an NHLBI study in the past. Participants will be asked if they would like to be contacted for other current or future studies. If they say no, they will not be contacted. But their data will stay in the database. They can also withdraw from the registry. If they do, their reason will be recorded in the database. The registry will be created and maintained by the Office of the Clinical Director at NHLBI.
This is a Phase 1, randomized, open-label, 2-way crossover, pharmacokinetic study in adult patients with hematological malignancies eligible to receive either cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) regimen or rituximab-CHOP (R-CHOP) regimen.
Immunotherapy with Chimeric Antigen Receptor (CAR) T Cells, T cells whose receptor has been genetically modified, is based on improving the immune response against the tumor. This approach is promising for patients with hematologic malignancies refractory to chemotherapy. Despite impressive results, too many patients are relapsing. The reasons for the relapse, after the injection of CAR T cells, need to be explored. In this context of newly introduced therapeutics, it is essential to better understand the factors associated with the response to treatment with CAR T Cells, especially the characteristics of the tumor and its microenvironment. The objective of this study is to understand the role of tumor biology, and its microenvironment, in the response to CAR-T Cells therapy in patients with hematologic malignancies
Beta thalassemia has many complications on many systems as the renal system.So early detection of renal impairment is required in those children to decrease complications of this nephropathy.
The purpose of this study is to obtain ovarian tissue from female patients undergoing gonadotoxic treatments or gonadal ablating surgery, and that in consequence may see their future fertility impaired. Participants will be offered to preserve (freeze) and use ovarian tissue for the purpose of conceiving in the future. Although, 86 live births have been reported with ovarian tissue cryo-preservation and grafting, the procedure is still considered experimental. This research, will help us to learn and validate how to perform ovarian tissue cryo-preservation and thawing in the fertility preservation context.
