Voxelotor Neurocognitive Function Study

Sickle Cell Disease

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.

Identifying Barriers and Strategies to Support Self-efficacy for Medication Adherence With Text...

Sickle Cell Disease

The investigators will explore barriers to improving self-efficacy, or the ability to feel in control of their disease, and medication adherence with text messaging through surveys and interviews with adolescents and adults with SCD cared for at the Vanderbilt Meharry Center of Excellence (VMCE) in Sickle Cell Disease (SCD). The investigators will identify preferences to improve and sustain adherence to daily medication through selection of investigator-proposed or patient-generated text messaging strategies. Finally, the investigators will fill in the literature gaps by describing barriers to self-efficacy and medication adherence among adults with SCD as well as adolescents with SCD who are transitioning to adult care.

Feasibility Study of Unfractionated Heparin in Acute Chest Syndrome

Acute Chest SyndromeSickle Cell Disease

The purpose of this study is to determine the feasibility of performing a larger multicenter phase III trial to assess the effects of unfractionated heparin (UFH) in acute chest syndrome (ACS). Prespecified feasibility criteria consists of the ability to enroll potential study participants, which includes the timely notification of hospitalized patients with ACS, the capacity to consent eligible individuals, and the ability to appropriately randomize eligible patients within 24 hours of diagnosis. Additional feasibility objectives involve ensuring appropriate eligibility criteria, proper administration of the study drug, and the ability to completely and accurately collect clinical data of interest. The final aim of our pilot study is to provide preliminary data, with respect to treatment effect and variance, to allow sample size calculation in a larger trial given the lack of data available to help guide this process. The investigators hypothesize that the use of UFH in ACS will result in a decrease in the duration of hospitalization and improve other clinical outcomes, such as the duration of hypoxemia and duration of moderate to severe pain.

Efficacy, Safety Study and Benefit of Alkali Therapy in Sickle Cell Disease

Sickle Cell AnemiaChronic Kidney Disease1 more

The objective of this study is to assess the effect of alkali administration on bicarbonate and potassium levels in patients with Sickle Cell Disease (SCD) and depressed serum bicarbonate levels. The study is a prospective non-blinded evaluation of tolerability and efficacy of alkali repletion with 4 weeks of observation and two sequential 4 week courses of escalating oral sodium bicarbonate treatment.

Efficacy and Safety of Bosentan in Sickle Cell Disease (SCD) Patients Diagnosed With Pulmonary Hypertension...

Pulmonary Hypertension

The study will assess the effect of bosentan on pulmonary vascular resistance and exercise capacity in Sickle Cell Disease (SCD) patients diagnosed with Pulmonary Hypertension. It consists of 3 phases: screening, treatment and follow-up. During the screening visit, the study doctor will decide if patients meet the study requirements. All potential patients will have a diagnosis of increased pulmonary artery pressures that is shown by right heart catheterization conducted shortly prior to start of study treatment. Patients will be asked to perform exercise capacity test (walking as far as possible for 6 minutes). Following the baseline visit the treatment phase consists of 4 additional clinic visits during which the good and bad effects of the drug are reviewed and exercise capacity test will be repeated. Patients will be treated for 16 weeks. Blood samples will be collected every month, or more often, if needed. At the end of the study some of the patients will be asked to repeat the right heart catheterization. All patients will repeat an exercise capacity test. After completion of the study, patients will have the option of enrolling in a long-term follow-up study where all patients will receive active drug. Patients electing not to participate in the extension study will be followed up for safety assessments for about 28 days after the end of the study treatment.

Study of MGTA-145 and Plerixafor in Patients With Sickle Cell Disease

Sickle Cell Disease

This research study is designed to investigate a new potential medicine for mobilizing stem cells and apheresis collection in patients with Sickle Cell Disease. MGTA-145, the new potential medicine, will be given with plerixafor.

Ketamine Infusion for Acute Sickle Cell Crisis in the Emergency Department

PainSickle Cell Disorder

Pain associated with sickle cell disease is a common emergency department visit. It is also frequently associated with a high emergency department recidivism rate for pain control and admissions to the hospital. Opiates are considered the first line therapy for acute flares and to manage chronic pain. This often times leads to a stigma of being "opiate seekers" or "frequent fliers". With this study, we wish to explore whether adding ketamine to standard acute opiate therapy (morphine or dilaudid) will decrease subsequent repeat doses of opiates while improving the patient's perception of pain. In addition, we will be exploring whether ketamine as an adjuvant therapy can help reduce hospital admissions for the management of acute sickle cell crisis pain.

Comparing Individualized vs. Weight Based Protocols to Treat Vaso-Occlusive Episodes in Sickle Cell...

Sickle Cell Disease

The purpose of this research study is to compare two different ways to give opioid pain medicine to treat sickle cell disease pain that is bad enough to go to the emergency department for treatment. One way uses your weight to decide how much pain medicine to give you while in the emergency department. This is called weight based treatment. The other way uses how much pain medicine you take at home and how much medicine you needed during past emergency department visits to decide how much medicine to give you. This is called patient specific treatment.
