Active clinical trials for "Anemia, Sickle Cell"

Safety and effect of SANGUINATE on Sickle Cell Disease patients experiencing a vaso-occlusive crisis

The purpose of this study is to assess the maximum tolerated dose, safety and pharmacokinetics of an investigational drug, intravenous (IV) citrulline, in subjects in steady-state sickle cell disease.

Stress is known to trigger acute pain crisis of sickle cell disease (SCD). SCD is an inherited blood disorder that afflicts about 100,000 people in the United States, and is among the most common lethal genetic diseases in the United States. Though worldwide in distribution, in the US it is most commonly found in African Americans. Its best known complication is severe, recurrent relentless pain, often known as pain crisis. Non-drug treatment for SCD pain such as cognitive coping interventions have been shown to be effective for reducing SCD pain intensity, but they are complicated, multifaceted, and time-consuming. A simple and cost-effective alternative such as guided imagery (GI) could reduce the effect of stress on SCD pain. GI is an intervention where patients listen to and view audio-visual recordings while being directed to visualize themselves being immersed in that scene or scenario. There are no published studies on the use of GI as a simple stress coping intervention or tracking stress in a systematic manner as a trigger for SCD pain.

This is a clinical trial that will compare survival and sickle related outcomes in adolescents and young adults with severe sickle cell disease after bone marrow transplantation and standard of care. The primary outcome is 2-year overall survival.

The purpose of this study is to learn if it is possible and safe to treat persons with severe sickle cell disease (SCD) by bone marrow transplant (BMT) from human leukocyte antigen (HLA) half-matched related donors. Preparation before transplant includes the chemotherapy drugs hydroxyurea, fludarabine, thiotepa, anti-thymocyte globulin, and cyclophosphamide. It also includes radiation.

The purpose of this study is to determine the safety, pharmacokinetics, and pharmacodynamics of NKTT120 in adult patients with stable sickle cell disease.

Our primary objective is to assess whether inhaling vaporized cannabis ameliorates chronic pain in patients with sickle cell disease (SCD). As these patients will all be on chronic opioid analgesics, the investigators will also assess the possible synergistic affect between inhaled cannabis and opioids. The investigators will also assess the clinical safety of the concomitant use of cannabinoids and these opioids in patients with SCD by monitoring the short-term side effects associated with combined therapy. Finally, the investigators will evaluate the short-term effects of inhaled cannabis on markers of inflammation and disease progression in patients with SCD. Hypotheses are as follows: Inhaled cannabis will significantly reduce chronic pain in patients with SCD. Inhaled cannabis will significantly alter the short-term side effects experienced by patients who take opioids for SCD. Inhaled cannabis will significantly alter markers of inflammation and disease progression in patients with SCD compared to placebo.

Part 1: A pilot study in patients with homozygous S (HbSS) or hemoglobin S with beta zero thalassemia(HbS-βo thalassemia), with the aim of examining the effect of intravenous NAC treatment on plasma VWF parameters and measures of redox and RBC function. Part 2: A pilot study in patients with sickle cell disease admitted to the hospital in vaso-occlusive crisis to determine the effects of NAC infusions on plasma VWF parameters and measures of redox and RBC function, and on measures of pain and hospital length of stay.

Given large absolute numbers of individuals with sickle cell disease in Nigeria, hydroxyurea therapy for all individuals with sickle cell disease may not be initially feasible; however, a targeted strategy of hydroxyurea use for primary prevention of strokes is an alternative to the standard therapy (observation) for high-risk individuals. The investigators propose a feasibility study, Sickle Cell Disease - Stroke Prevention in Nigeria (SPIN) Trial, to determine whether hydroxyurea can be used for primary prevention of strokes in Nigerian children with sickle cell anemia.
