Active clinical trials for "Hemoglobinopathies"

This study's goal is to determine the frequency and severity of acute graft versus host disease, to evaluate incidence of primary and secondary graft rejection, to assess event free survival and overall survival, to determine the time to neutrophil and platelet engraftment, to determine the time to immune reconstitution (including normalization of T, B and natural killer (NK) cell repertoire and Immunoglobulin G production), and to establish the incidence of infectious complications including bacterial, viral, fungal and atypical mycobacterial and other infections following CD34+ selection in children, adolescents and young adults receiving an allogeneic peripheral blood stem cell transplant from a family member or unrelated adult donor for a non-malignant disease.

Allogeneic blood or marrow transplantation (alloBMT) is a curative therapy for a variety of hematologic disorders, including sickle cell disease and thalassemia. Even when it is clear that alloBMT can give to these patients an improvement in their disease, myeloablative transplants have important toxicities and mortalities associated. The lack of suitable donors continues to be a limit to access to transplantation. Substantial progress has been made recently in the development of pre-treatment regimens that facilitate the sustained engraftment of donor marrow with reduced toxicity. Most of these regimens incorporate highly immunosuppressive drugs, which allow the reduction or elimination of myeloablative agents or total body irradiation without endangering the sustained engraftment of HLA-identical allogeneic stem cells. Preliminary results of non-myeloablative allogeneic stem cell transplantation suggest that the procedure can be performed in patients who are ineligible for myeloablative alloBMT, and that sustained remissions of several hematologic malignancies can be obtained.

This study will investigate the role of genetic modifiers in hemoglobinopathies through a large-scale, multi-ethnic genome-wide association study (GWAS).

The primary objective of this study is to establish a mechanism to obtain discarded bone marrow-containing bone samples from hemoglobinopathy, as well as non-hemoglobinopathy individuals. The processing of samples will help to understand how best to manipulate HSPC's from hemoglobinopathy patients with gene therapy and gene technologies in the laboratory environment. It will also allow us to establish a reservoir of samples that can be studied in the future to assess cellular function and fitness for transplant. Secondary objectives To develop gene transfer and gene editing strategies as potentially curative therapy for hemoglobinopathies (e.g. sickle cell disease (SCD) and β-thalassemia). To develop a drug treatment strategy which elevates the expression of fetal hemoglobin to a potentially curative level for hemoglobinopathies. To examine the biology of bone marrow cells isolated from patients with hemoglobinopathies.

Patients with medical conditions requiring allogeneic hematopoietic cell transplantation (allo-HCT) are at risk of developing a condition called graft versus host disease (GvHD) which carries a high morbidity and mortality. This is a phase I/II study that will test the safety and efficacy of hematopoietic cell transplantation (HCT) with ex-vivo T cell receptor Alpha/Beta+ and CD19 depletion to treat patients' underlying condition. This process is expected to substantially decrease the risk of GvHD thus allowing for the elimination of immunosuppressive therapy post-transplant. The study will use blood stem/progenitor cells collected from the peripheral blood of parent or other half-matched (haploidentical) family member donor. The procedure will be performed using CliniMACS® TCRα/β-Biotin System which is considered investigational.

The COVID-19 pandemic is causing many deaths around the world, putting a strain on health services. Patients with pre-existing chronic conditions are most affected by the SARS-COV2 infection. Infectious complications are a common cause of mortality and one of the main causes of morbidity in all these diseases. The main objective of this project is the assessment of patients with thalassemia, drepanocytosis, other haemoglobinopathies and rares inherited anemias suffering from SARS-COV-2 to: Obtain clinical and epidemiological data that can provide information on a possible increased vulnerability of these patients to SARS-COV-2 infection; Sharing therapeutic approaches considering the lack of information about the treatment.

This is a multi-site, observational study to evaluate the long-term safety and efficacy of CTX001 in subjects who received CTX001 in Study CTX001-111 (NCT03655678) or VX21-CTX001-141 (transfusion-dependent β-thalassemia [TDT] studies) or Study CTX001-121 (NCT03745287) or VX21-CTX001-151 (severe sickle cell disease [SCD] studies; NCT05329649).

The Trial aims to increase the information available on the relevance of tumor pathology in hemoglobinopathies, updating the data relating to hepatocarcinoma and investigating which other tumors are more frequent in patients with hemoglobinopathies. Still, in relation to tumor pathology, the study will evaluate any differences between the different types of hemoglobinopathy and will investigate the association between the appearance of neoplasms and risk factors such as age, sex, iron accumulation markers, history of bone marrow transplant, and others.

This prospective monocentric study project is to identify hemoglobinopathies in pregnant women in order to optimize antenatal care and to investigate the prevalence of hemoglobinopathies in pregnant women in Switzerland.

CordIn™ is a cryopreserved stem/progenitor cell-based product of purified CD133+ cells composed of ex vivo expanded allogeneic UCB cells. The overall study objectives are to evaluate the safety and efficacy of CordIn™.
