Filter by: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
This is a multi-site, open- label rollover study to evaluate the long-term safety and efficacy of CTX001 in pediatric and adult participants who received CTX001 in parent studies 111 (NCT03655678) 141 (NCT05356195) or 161 (NCT05477563) (transfusion-dependent β-thalassemia [TDT] studies) or Study 121 (NCT03745287) or 151 (NCT05329649), 161(NCT05477563),171 (NCT05951205) (severe sickle cell disease [SCD] studies).
The purpose of the study is to evaluate the effectiveness of Creative Arts Therapy (CAT) on pediatric patients undergoing chemotherapy in the Infusion Center at Children's Hospital Colorado Center for Cancer and Blood Disorders. Findings from a previous pilot study support the hypothesis that CAT may improve quality of life (QOL), resiliency, physical posture, and emotional response to pain of pediatric oncology patients undergoing chemotherapy.
The goal of this prospective comparative interventional cohort study is to assess the fertility status of young adult men (≥18 years) who received gonadotoxic treatment during childhood for the treatment of cancer or hematological disorders. These treatment protocols are highly gonadotoxic (i.e. they may cause later fertility problems) and therefore these patients have been proposed to store some testicular tissue during childhood as an option to preserve their fertility. The main questions this study aims to answer are (1) the impact of the received gonadotoxic treatment on the later fertility status and (2) the additional impact of a testicular biopsy procedure (performed at a young age to harvest testicular tissue for storage) on the future fertility. Participants will be asked to undergo a physical examination by a fertility specialist, to undergo a scrotal ultrasound, to give a blood sample, and to provide a semen sample. Researchers will compare the patients' fertility status between the different received gonadotoxic treatment protocols, between patients who underwent a testicular biopsy procedure at a young age and those who did not, and compare the patients' fertility status with the reproductive health of spontaneously conceived young adults.
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.
The bone marrow aspiration and biopsy (BMAB) is an essential and indispensable examination for the diagnosis and the follow-up of the hematological diseases but which remains painful and dread by the patients. Until then it was performed manually using a trocar. It is now practiced most often using a tool (like a small drill), device that pierces through the external iliac bone to extract a bone cylinder that will be analyzed If the gesture is faster than with the manual method, it remains overall painful and the noise generated by the drill that passes through the periosteum of the iliac bone is impressive for the patient. Prevention measures to limit pain and anxiety are put in place during the examination: local anesthesia, with or without a lidocaine patch, as well as inhalation of a mixture of nitrous oxide and oxygen (MEOPA®). These, recommended by the "Standards, Options, Recommendation" (SOR) often remain insufficient and are not devoid of undesirable effects. Despite these precautions, several studies show that the action remains painful and anxiety-provoking. An exploratory survey carried out in the hematology department of the François Baclesse Center in 2013 confirms these results and specifies that the pain remains present for another 30 minutes after the examination. The investigators believe that associating a psycho-corporeal technique, as is sophrology, with the usual care, could contribute to the decrease of the threshold of pain and anxiety during the BMAB and avoid the use of a premedication. The effectiveness of sophrology as a complementary technique in the field of pain prevention in invasive procedures is recognized by observations and clinical results. This complementary therapy, among others, has its place in the hospital. To date, to investigator's knowledge, there is no published, randomized study evaluating the effectiveness of sophrology on pain in invasive procedures. The investigators propose a study whose main objective is to evaluate the effectiveness of a session of sophrology on the pain felt during the realization of the BMAB, in patients with hematological malignancy. This session will be provided by a sophrologist nurse This study should include 90 patients undergoing a BMAB over a 24-month period.
PURPOSE: To investigate the effect of the disease and HSCT on muscle dysfunction and to investigate the prognostic role of muscle dysfunction at critical decision points in patients with hematological diseases referred to hematopoietic stem cell transplant (HSCT). HSCT: Patients diagnosed with malignant hematological diseases who are referred to myeloablative HSCT, to a myeloablative "reduced toxicity conditioning" regime with Fludarabine and Treosulfane (FluTreo) or to non-myeloablative HSCT.
Richness and diversity of gut microbiota are increasingly found to be associated with cancer outcomes. Moreover, an adequately responsive immune system seems to rely on the existence of a functioning gut ecosystem that includes the microbiota and its natural environment. Cancer by itself, but also cancer treatments - in particular chemotherapy - induce gut dysbiosis, impair the constant reparation mechanisms of the gut epithelium, disrupt immune homeostasis, and stunt immune responsiveness. The objective of MaaT033 is to (1) prevent the decay of the gut ecosystem (dysbiosis) to preserve immune homeostasis, (2) restore and optimize the gut ecosystem to full functionality including its role in repairing the gut epithelium and healthy gut barrier, and (3) maintain a restored gut ecosystem and fully functional immune homeostasis. Restoring the full gut ecosystem and its associated microbiota could become an important therapeutic option to improve clinical outcomes and control adverse events of conventional approaches, including immunotherapy in cancer patients. As a first step, MaaT033 capsules containing lyophilized, pooled, full-ecosystem microbiota in its natural environment are to be tested for their safety and tolerability in hematological malignant patients, who are exposed to intensive rounds of chemotherapy and antibiotics.
This phase II trial studies how well itacitinib works in preventing graft versus host disease in patients with blood disorders undergoing donor stem cell transplantation. A donor transplantation uses blood-making cells from a family member or unrelated donor to remove and replace abnormal blood cells. Graft versus host disease is a reaction of the donor's immune cells against the patient's body. Itacitinib plus standard treatment may help prevent graft versus host disease in patients who have received a donor stem cell transplantation.
