Active clinical trials for "Anemia, Sickle Cell"

The purpose of this study is to determine the effects of transfusion of fresh and stored blood on patients. The investigators hope to test: whether a similar effect (older stored blood is associated with worse outcomes) is seen in chronically transfused patients with hemoglobinopathies. This patient population will also allow the investigators to test whether iron- chelation therapy is beneficial in this setting. whether washing or cryopreserving the red blood cells has any effect on this outcome. These findings may explain the immunomodulatory effects of older stored blood in patients and will help us develop safer transfusion products for patients.

The main purpose of the study is to evaluate the efficacy and safety of the study drug known as prasugrel for the reduction of Vaso-Occlusive Crisis events in pediatric participants with sickle cell disease. The study will also investigate reduction in daily pain in children who have sickle cell disease.

This study will determine if administration of sodium nitrite is safe and can improve small vessel blood flow and tissue oxygenation when given as an additional treatment in patients with acute vaso-occlusive crisis (pain crisis) associated with sickle cell disease.

The primary purpose is to evaluate the effect of L-glutamine therapy on exercise endurance and breath by breath exercise response of sickle cell anemia patients The secondary purpose is to assess the effect of L-glutamine on incidence of painful crises; level of chronic pain, and amount of daily requirement for narcotics.

The goal of this study is to test the hypothesis that hydroxyurea is effective for the specific treatment of secondary pulmonary hypertension found on screening in children and young adults with sickle cell disease.

Randomized, double blind placebo controlled clinical trial to evaluate effectiveness and safety of inhaled nitric oxide for the treatment of sickle cell painful crisis in pediatric patients with sickle cell disease.

This study assesses if using the medication desmopressin will decrease nightime bedwetting in children with sickle cell disease.

This study is a first-in-human, single-arm, open-label Phase I/II study of GPH101 in approximately 15 participants, diagnosed with severe Sickle Cell Disease. The primary objective is to evaluate safety of the treatment in this patient population, as well as preliminary efficacy and pharmacodynamic data.

This is a long-term follow up study evaluating the safety of BPX-501 T cells (rivogenlecleucel) and infused in pediatric patients previously enrolled on the BP-004 study.

This is a Phase 3b, randomized, double-blind, placebo-controlled, multicenter study to assess the treatment effect of voxelotor on neurocognitive function as assessed by the National Institute of Health (NIH) Toolbox Cognition Module of executive abilities in pediatric participants (8 to < 18 years) with SCD.
