Active clinical trials for "Anemia, Sickle Cell"

Investigators hypothesize that administration of ketamine for pain relief in sickle cell patients with vaso-occlusive crisis early on will lead to a more rapid improvement in pain score and less narcotic requirement.

The purpose of this study is to evaluate the safety and efficacy of autologous bone marrow stem cell implantation for the treatment of leg ulcer in adult patients with sickle cell disease.

The objective of this study is to assess the efficacy of SC411 in reducing the number of sickle cell crisis (SCC) events in sickle cell disease (SCD) subjects receiving SC411 compared to those subjects receiving placebo.

To assess the tolerability of the costimulation blocking agent abatacept (CTLA4-Ig) when added to the standard graft versus host disease (GVHD) prophylaxis regimen of a calcineurin inhibitor and methotrexate in patients receiving early alemtuzumab followed by fludarabine, thiotepa, melphalan, and alemtuzumab for conditioning.

The purpose of this study is to determine the antioxidant effect of prolonged use of sorghum bicolor (jobelyn) to increase the level of plasma superoxide dismutase and glutathione reductase in patients with sickle cell disease and to determine if there is any improvement in the quality of life of the patients.

The investigators plan to obtain skin and blood samples from healthy volunteers and patients with a benign, inherited hematologic disease to use for research to use homologous recombination to correct β-globin gene mutations in therapeutically useful cells, like autologous induced pluripotent stem cells from sickle cell anemia patients.

To evaluate PK and PD responses to L-citrulline given orally for four weeks to patients with sickle cell disease who are otherwise healthy.

Patients with sickle cell disease (SCD) and cancer often have complicated courses while hospitalized and often deal with pain, anxiety and depression. Advances in the field of technology provide potential avenues for innovative and improved care models for our patients. Virtual reality (VR) has been recently utilized to improve anxiety and pain in a variety of patient populations including children undergoing elective surgery and children experiencing intravenous cannulation in the Emergency Department. Patients with SCD and cancer, both adults and children, are a group of patients that can benefit from VR as part of their care. Over the past four years, our team has successfully implemented several self-developed mobile applications ("apps") for our patients, in addition to integrating objective data (heart rate, activity, stress) from wearable activity trackers. The investigators now propose implementing a feasibility study followed by a pilot study and randomized-controlled trial of the use of VR in patients with SCD and cancer. The investigators plan to assess pain and anxiety prior to the session as well as following the session in hospitalized patients and outpatients with SCD and cancer. The sessions will include a ten-minute relaxation response introductory narrative segment (deep breathing and mindfulness) followed by a ten-minute narrated and immersive VR. Heart rate will be tracked using an Apple iWatch for 30 minutes prior to the session, during the session, and following the session. We anticipate VR will not only be a feasible method to provide non-pharmacologic treatment, but will also significantly reduce pain and anxiety.

Symptomatic sickle cell disease (SCD) is worldwide the most frequent cause for hereditary hemolytic anemia with recurrent pain crises. Hemolysis, vaso- occlusive and pain crises are hallmarks of this disease and are causative for an important socio-economic burden worldwide, especially in Africa. Aside from allogenic stem cell transplantation, which is rarely available and very expensive, at present there is no curative treatment for patients with SCD. The current standard of care includes treatment with Hydroxyurea and symptomatic care such as transfusions, antibiotic/analgesic treatment. Recent findings allowed the investigators to come up with a novel pharmacological target for prophylactic treatment of this group of patients. The investigators showed that N-methyl D-aspartate receptors (NMDARs) are substantially up-regulated in circulating red blood cells (RBCs) of SCD patients. Ca2+ uptake via these non-selective cation channels has major impact on RBC hydration and facilitates polymerization of deoxygenated hemoglobin S variant in RBCs of patients. In vitro observations shows that inhibition of NMDARs with Memantine caused re-hydration and largely prevented hypoxia-induced sickling in RBCs. A pilot trial MemSID (NCT02615847) was conducted in August 2015-March 2017 at the Hematology Division of University Hospital Zurich. A small cohort of adult SCD patients was treated with 20 mg Memantine daily to test safety, tolerability and efficacy of this drug and to assess the effect of Memantine on hemolytic activity and RBC stability. Pilot data reveal safety and an impressive therapeutic potential of Memantine in treating SCD patients. Due to a small number of SCD patients in Switzerland, an extended trial including larger number of adult and adolescent patients will be performed at the Pediatric Hematology Unit of the Emek Medical Center in Afula, Israel

The purpose of this study is to evaluate the safety and efficacy of autologous bone marrow stem cells in sickle cell disease patients with osteonecrosis
