We are developing a computer-based tool for people who have cancers of the blood, bone marrow, and lymph nodes. This tool will help us understand what is most important to patients when it comes to the results of their treatment. We are looking for healthy volunteers (those without cancer) to help us test the usability of this tool.

The purpose is to evaluate coagulation activation and the impact of iron status in patients with Hereditary Hemorrhagic Telangiectasia (HHT). Participants on this study will include patients with HHT, patients with iron deficiency +/- anemia but without HHT, and healthy volunteers The study team will procure single and/or serial blood samples from participants and assess various markers of hemostasis and activation of coagulation, and host iron status.

The primary objective of the study is to evaluate the safety and feasibility of treating patients with a history of iTTP with efgartigimod, an FcRn inhibitor that reduces IgG autoantibodies, including those responsible for ADAMTS13 depletion.

To evaluate the effect of mitapivat on albumin creatinine ratio (ACR) response in subjects with sickle cell disease (SCD) and nephropathy

To have a well phenotyped cohort of people with sickle cell disease in order to examine risk factors for end organ disease through the creation of a multi-site registry and to develop a repository for the long-term storage of patient samples (whole blood, peripheral blood, serum) along with corresponding demographic and clinical information to allow for clinical and laboratory correlations.

Study the effectiveness and safety of Epeleuton

Purpose: Evaluate the efficacy of prophylactic Emicizumab administered on a scheduled basis to prevent bleeds in patients with acquired hemophilia A (AHA).

This study is being done to answer the following question: Do two different anti-cancer drugs, paclitaxel (PTX) and pegylated liposomal doxorubicin (PLD) have similar effects on treating KS in PLWH in sub-Saharan Africa? We are doing this study because we want to find out if one of these approaches, PTX or PLD, is better than the other for KS. Both drugs may be given as part of the usual approach for your KS. The usual approach is defined as care most people get for KS.

The main purpose of this clinical research study is to assess the safety, tolerability, efficacy (the ability of the study drug to produce the desired anti cancer effect), PK] and PD of GHF009X2101 the study drug in patients with relapsed or refractory hematologic malignancies including AML, CLL, SLL or other lymphomas [including other leukemia].

The purpose of this research study is to improve safety measures and reduce stressors associated with lumen hub-clave seizures when caring for patients with CVCs. The primary outcome of the pilot study is to document the types and frequency of workarounds employed, current disinfection techniques, and the stressors of those caring for and accessing CVCs.
