This study will assess the appropriate dosing and evaluate the safety of crizanlizumab in pediatric sickle cell disease patients. The study is for male and female subjects between the ages of 6 months to 17 years old who have experienced at least one pain crisis within a 12 month period. The drug is given via an IV infusion in an outpatient setting and has the potential to reduce the amount of sickle cell pain crisis a participant may experience. Participants can expected to participant in this study for up to 2 years.
This study will assess the effect of ticagrelor versus placebo in reducing the rate of pain crisis in sickle cell disease patients. The study is for male and female subjects between the ages of 2 to 17 who have experienced at least two pain crisis within a 12 month period. The drug is given by mouth in an outpatient setting and consists of 13 visits over an 18 month period.
This is a first-in-humans gene therapy study for subjects diagnosed with severe hemophilia A. A one time infusion of the gene therapy product (BAX888) will be given with the hope of eliminating or reducing the need for prophylactic and/or on-demand use of FVIII concentrate therapy. Up to 10 subjects will be enrolled study-wide with up to two subjects enrolled at MUSC. This study will require weekly visits to the study clinic after initial infusion for the first 15 weeks followed by monthly visits for the first year. Compensation will be provided.
This is a study to determine the use of recombinant Von Willebrand Factor (rVWF) in the treatment and control of nonsurgical bleeding episodes and bleeding during elective and emergency surgery in children with severe Von Willebrand Disease. The study will last approximately 14 months and will involve regular visits to a research clinic.
This study is meant to compare transplant to standard care (regular care) for sickle cell patients. By comparing the health outcomes for patients who receive bone marrow transplant to those patients who receive standard of care, this study will be able to determine whether the two treatments are the same, or if one is better than the other.
Study participants in this study will be recruited because of development of a clot. Clots in pediatric patients are typically treated with blood thinner medicine for 3 months (sometimes longer, depending on confounding factors). It is possible that treatment for 3 months may be longer than needed in children whose clots do not block blood flow through the vein after 6 weeks of treatment.
Over a period of five years, up to 750 children will be enrolled in this study internationally. Each participant will be randomized to a total of 6 weeks or 3 months of venous thrombosis treatment. Doppler ultrasounds of the blood clot will be taken at approximately 6 weeks after diagnosis of the blood clot (the time of the first picture). If the picture at 6 weeks shows that the blood clot is completely blocking blood flow through the vein, the patient will still be followed in the study, but will not be eligible to get the 6 week length of blood thinner treatment. Instead, the patient will receive the usual length of treatment (3 months).
Patients initially positive with an antiphospholipid antibody test that was still positive at approximately 6 weeks after diagnosis of the blood clot, will still be followed in the study, but will not be eligible to get the 6 week length of blood thinner treatment. Instead the primary doctor will decide length of treatment as part of standard care, which will be at least 3 months in total, and possibly much longer.
At the 6 week and 3 month visits, the patient will have an additional 10 mL (2 teaspoons) [for infants: 6 ml, or just over 1 teaspoon] of blood drawn for clotting research tests designed to identify new risk factors for blood clots and their long-term effects.
