The purpose of the study is to examine the clinical and biological effects of 177Lu-PSMA-617 in mCRPC patients with cytopenia\[s\].

This study is being done to determine the feasibility and safety of using a novel dose adjusted apixaban for the management of participants with cancer-associated venous thromboembolism (blood clot) or and thrombocytopenia (low number of platelets in the blood). Investigators are also looking to see if participants on this treatment have fewer bleeding episodes. The name of the study drug involved in this study is: -Apixiban (a type of anticoagulant)

The purpose of this clinical trial is to test how well the drug luspatercept works in improving low blood cell counts in people with clonal cytopenias of uncertain significance (CCUS). The main questions the study seeks to answer include: * How many patients experience improvements in their low blood counts (red cells, platelets, or white cells) within 24 weeks, based on specific criteria for blood conditions like myelodysplastic syndromes (MDS)? * How long these improvements last before the condition worsens or changes. * The percentage of participants showing improvements at 12, 24, and 48 weeks. * How long it takes for the condition to progress to more severe diseases like myeloid disorders. * How long red blood cell responses last and how quickly these responses are seen. * The average change in hemoglobin levels over 24 weeks. * How many patients need blood transfusions during the study and how soon transfusions are required. * Changes in participants' well-being and energy levels based on a standardized questionnaire. * Monitoring for any side effects, including progression to MDS or leukemia, heart-related issues, or sudden increases in hemoglobin. Participants will: * Receive luspatercept as an injection every three weeks. * Visit the clinic every three weeks for treatment and monitoring.

The objective of the NeoPlaTT trial is to test whether, among extremely preterm infants born at 23 0/7 to 26 6/7 weeks' gestation, a lower platelet transfusion threshold, compared to a higher threshold, improves survival without major or severe bleeding up to 40 0/7 weeks' postmenstrual age (PMA).

A phase II trial of a reduced intensity conditioned (RIC) allogeneic hematopoietic cell transplant (HCT) with post-transplant cyclophosphamide (PTCy) for idiopathic severe aplastic anemia (SAA), paroxysmal nocturnal hemoglobinuria (PNH), acquired pure red cell aplasia (aPRCA), or acquired amegakaryocytic thrombocytopenia (aAT) utilizing population pharmacokinetic (popPK)-guided individual dosing of pre-transplant conditioning and differential dosing of low dose total body irradiation based on age, presence of myelodysplasia and/or clonal hematopoiesis.

The objective is to determine the effectiveness of pulsatile flow during cardiopulmonary bypass to reduce the incidence of acute kidney injury after cardiac surgery. Investigators will also evaluate the safety and impact of pulsatile flow on clinical outcomes compared to non-pulsatile flow during cardiopulmonary bypass.

Background: Immune bone marrow failure is a condition that occurs when a person s immune system attacks the cells of the bone marrow. This can lead to diseases including different types of anemias and blood cancers. Some of these diseases can be deadly. Better treatments are needed. Objective: To test a drug (ruxolitinib) in people with different types of immune bone marrow failure. Eligibility: Adults aged 18 and older with an immune bone marrow failure. Design: Participants will be screened. They will have a physical exam. They will give samples of blood and saliva. They will have a bone marrow biopsy: A large needle will be inserted into a small cut to remove a sample of the soft tissue inside the bone. Some participants may have a skin biopsy: A small piece of skin will be removed. Some may have a computed tomography (CT) scan: They will lie on a table that slides into a donut-shaped machine that uses X-rays to make pictures of the inside of the body. Ruxolitinib is a tablet taken by mouth. Participants will take the drug twice a day for up to 6 months. Participants will have blood tests every week while they are taking the drug. These tests can be done by the participant s own physician and the results sent to the researchers. Participants will have clinic visits after taking the drug for 3 months and 6 months and then after 1, 2, and 3 years. The blood tests and bone marrow biopsy will be repeated. Participants who improve while taking the drugs may go on to an extension phase of the study.

Open-label randomized controlled trial to test the effectiveness of whole blood transfusion for improving survival in children with severe malaria complicated by thrombocytopenia.

This trial tests a special stem cell transplant for patients with serious conditions. It removes harmful immune cells from the donor's blood to lower the risk of complications, potentially reducing the need for strong medications afterward.

The purpose of this study is to see if the study drug, romiplostim, helps low platelet count caused by standard chemotherapy treatment for lymphoma. This study will also look at whether romiplostim can prevent the need for chemotherapy dose delays, chemotherapy dose reductions, and platelet transfusions. In addition, we will determine how safe it is to give romiplostim to people with lymphoma who have low platelet count from chemotherapy.

This research is being done to learn if a new type of haploidentical transplantation using TCR alpha beta and CD19 depleted stem cell graft from the donor is safe and effective to treat the patient's underlying condition. This study will use stem cells obtained via peripheral blood or bone marrow from parent or other half-matched family member donor. These will be processed through a special device called CliniMACS, which is considered investigational.

Background: Severe aplastic anemia (SAA) is a rare and serious blood disorder. It causes the immune system to turn against bone marrow cells. Standard treatment for SSA is a combination of 3 drugs (Cyclosporine \[CsA\], Eltrombopag \[EPAG\], and horse anti-thymocyte globulin \[h-ATG\]). Researchers want to see if starting people at a lower dose of CsA with EPAG before giving them h-ATG is helpful. Objective: To learn if early initiation of oral therapy with CsA and EPAG is safe and effective in people who have SAA and have not been treated with a course of immunosuppressive therapy and EPAG. Eligibility: People ages 3 and older with SAA Design: Participants will be screened with: medical history physical exam electrocardiogram blood tests family history bone marrow biopsy current medicines. Participants may be screened remotely via telephone conference. Participants will take a lower oral dose of CsA and EPAG. They will take CsA twice a day for 6 months. They will take EPAG for 6 months. Those who cannot visit the NIH Clinical Center within 72 hours will start taking the drugs at home. They will have weekly telephone calls with NIH staff until they visit the Clinical Center. Participants may get h-ATG at the Clinical Center for 4 days. For this, they will have a central line placed. It is a plastic tube inserted into a neck, chest, or arm vein. Participants will repeat most screening tests throughout the study. Participants will have follow-up visits at the Clinical Center at 3 months, 6 months, and annually for 5 years after the start of the study....
