Active clinical trials for "Thrombocytopenia"

QL0911, a recombinant human thrombopoietin mimetic peptide-Fc fusion protein for injection, is a romiplostim (Nplate®) biosimilar for the treatment of primary immune thrombocytopenia (ITP). This phase III study aimed to assess the efficacy and safety of QL0911 in adult patients with primary chronic ITP.

This is a multi-center, observational study in patients with Immune Thrombocytopenia (ITP) or aplastic anemia(AA) designed to describe the real-world safety and effectiveness of hetrombopag and assess the patterns of drug utilization to add to the knowledge base regarding the use of hetrombopag in routine medical practice. Patients eligible for participation will, as part of their routine medical care, be receiving hetrombopag for the treatment of ITP/AA

The purpose of this study is to study the safety and efficacy of pooled buffy-coat derived platelets which had been frozen with dimethyl sulphoxide (DMSO), in the prevention of bleeding for patients with hypoproliferaitve thrombocytopenia. These platelets are hereafter referred to as cryopreserved platelets. Patients who have severely low platelet count due to impaired bone marrow function from chemotherapy or certain haematological conditions may need platelet transfusion to prevent spontaneous bleeding. Currently, platelets are stored in liquid form, and must be used within five to seven days of collection. In this study, DMSO is used to preserve platelets during freezing so that they can be stored for longer than five to seven days. Investigators hope to learn if thawed cryopreserved platelets are functional and safe for transfusion in humans.

Oseltamivirphosphate is hydrolysed to its active metabolite-the free carboxylate of oseltamivir. Oseltamivir is a neuraminidase inhibitor, serving as a competitive inhibitor of the activity of the viral neuraminidase (NA) enzyme upon sialic acid, found on glycoproteins on the surface of platelets. By blocking the activity of the enzyme, oseltamivir may prevent platelet destruction in liver.The project was undertaking by Qilu Hospital of Shandong University and other 4 well-known hospitals in China. In order to report the efficacy and safety of oseltamivirphosphate combined with high-dose dexamethasone for the treatment of immune thrombocytopenia (ITP) with high platelet desialylation level, compared to high-dose dexamethasone therapy.

NewGam is a newly developed human normal immunoglobulin solution for intravenous administration (IGIV). This study will evaluate the safety and efficacy of NewGam 10% in patients with primary immune thrombocytopenia.

To evaluate the efficacy of E5501 by measuring platelet response in subjects with chronic hepatitis C virus (HCV)-related thrombocytopenia who require antiviral treatment.

In this study, the investigators want to determine if N-acetylcysteine(NAC), given intravenously, will decrease complications in patients with Thrombotic Thrombocytopenia Purpura (TTP) who are receiving treatment with therapeutic plasma exchange (TPE). The investigators want to determine, through anti-oxidant activity, if NAC will have additional efficacy in TTP by improving cleavage of the patients' VWF by ADAMTS13, and preventing propagation of platelet/VWF strings. This will be manifest by a more rapid improvement in the patient's platelet count, decrease in number of days requiring TPE, and decrease in microvascular thrombotic complications. The investigators will additionally: 1) Assess safety of NAC by evaluating subjects for adverse events and significant adverse events 2) Determine effects on TTP by measuring clinical and research laboratory values 3) Determine drug effects by measuring clinical and research laboratory values.

This study is to evaluate the safety of intravenous (IV) infusion of dimethyl sulfoxide (DMSO) cryopreserved platelets (CPP) in participants with World Health Organization (WHO) Grade 2 bleed in spite of receiving a transfusion of liquid stored platelets (LSP) in the past 48 hours by collecting adverse events (AEs) and by evaluating coagulation-related parameters to assess the evidence of any thrombotic events after CPP or LSP transfusion.

The purpose of this study is to determine whether Recombinant Human Thrombopoietin (rh-TPO) in combination with Rituximab are effective and safe in the management of Steroid-Resistant/Relapsed Immune Thrombocytopenia (ITP).

This phase II trial studies how well giving fludarabine phosphate, melphalan, and low-dose total-body irradiation (TBI) followed by donor peripheral blood stem cell transplant (PBSCT) works in treating patients with hematologic malignancies. Giving chemotherapy drugs such as fludarabine phosphate and melphalan, and low-dose TBI before a donor PBSCT helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from the donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cell from a donor can make an immune response against the body's normal cells. Giving tacrolimus, mycophenolate mofetil (MMF), and methotrexate after transplant may stop this from happening
