Filter by:This study will evaluate the safety and tolerability of eltrombopag in the treatment of low platelet counts in adult subjects with advanced myelodysplastic syndrome (MDS), secondary acute myeloid leukemia after MDS (sAML/MDS), or de novo AML that are relapsed, refractory or ineligible to receive azacitidine, decitabine, intensive chemotherapy or autologous/allogeneic stem cell transplantation. This is a placebo-controlled study in which patients will receive study medication daily for 6 months, during which time the dose of study medication may be adjusted based upon individual platelet counts and bone marrow blast counts. All subjects will receive best standard of care (platelet transfusions, mild chemotherapy, cytokines, valproic acid, all-trans retinoic acid, ESAs or G-CSF) in addition to study medication. Subjects taking placebo may be allowed to crossover to eltrombopag treatment if a clinically and statistically significant improvement in bone marrow blast counts is seen in subjects treated with eltrombopag.
The purpose of this study is to further evaluate the effects that eltrombopag (and romiplostim) have on platelets in subjects with chronic ITP. Eltrombopag is approved by the Food and Drug Administration (FDA) for the treatment of low platelets in patients with chronic ITP. It is being further studied by GlaxoSmithKline (now Novartis) in other conditions associated with low platelets. This research study is being done because eltrombopag has been shown to increase platelet counts in a different way than other therapies for ITP. The investigators want to further study how eltrombopag and romiplostim affect subjects and their platelets to determine how the study drug should best be used in ITP treatment.
This is an open-label study in which oprelvekin will be administered for the prevention of severe low blood platelet cell counts (cells in your blood that keep bleeding and clotting stable) in adults with cancer who are taking chemotherapy (anti-cancer drug) that has a side effect of blocking your bone marrow from making platelet cells. The purpose of this study is to learn more about the effects of the recommended dose of oprelvekin on the heart's electrical cycle.
The aim of this study is to show the benefits for patients, with a high platelet count, iron deficiency and IBD, receiving intravenous iron therapy.
The purpose of this study is to collect data on the clinical management of Argatroban in patients with suspected or confirmed heparin-induced thrombocytopenia Type II, with or without ongoing thrombosis who require parenteral antithrombotic therapy
The purpose of this study is to test the hypotheses that argatroban significantly increases efficacy and safety of renal replacement therapy measured as life time of haemodialysis filters as compared to lepirudin

Thrombocytopenia (platelet count < 100,000/mL) occurs in approximately 15% of women with preeclampsia. Neuraxial analgesia is contraindicated in parturients with a coagulopathy; therefore, the platelet count(PC) is routinely checked prior to the initiation of neuraxial analgesia in women with preeclampsia/eclampsia. Catheter removal is also contraindicated in the presence of a coagulopathy. Some women have an acceptable PC at the initiation of neuraxial analgesia, but may become significantly more thrombocytopenic during labor and delivery. In a study of severely preeclamptic parturients, some with HELLP (H=hemolysis of red blood cells, EL=elevated liver enzymes, LP=low platelet count) syndrome, the admission PC correlated with the PC nadir. However, the natural progression of the PC has not been studied in women with mild preeclampsia. We hypothesize that women with mild preeclampsia or severe preeclampsia without HELLP syndrome, and whose admission PC is greater than 150,000/mL, will have a stable PC during the course of labor and delivery and do not require another PC check prior to initiation of neuraxial analgesia or removal of the epidural catheter. The purpose of this study is to determine the positive predictive value of an initial PC greater than 150,000/mL for maintaining a PC greater than 80,000/mL during labor and delivery.
Funding Source--FDA OOPD. Orphan Product Grant Number--1R01FD004091-01A1 Context: Wiskott-Aldrich syndrome (WAS) is a fatal, devastating disease with ill-defined treatment modalities, which affects young boys. Classic WAS is characterized by a clinical triad of thrombocytopenia, eczema and severe, recurrent infections. Despite diagnostic and therapeutic advances most WAS patients die at less than 12 years of age due to infections, hemorrhage, malignancy or complications from treatments. WAS patients suffer from herpesvirus infections as a result of poor Natural Killer (NK) cell function (cytotoxicity). In the laboratory, the investigators have seen correction of WAS Natural Killer Cell (NK) function after treatment with Interleukin-2 (IL-2). Objectives: Initiate a prospective clinical trial by treating WAS subjects with IL-2 and using safety as the primary endpoint. Restoration of NK cell cytotoxicity and effects on cytoskeletal dynamics are secondary endpoints. The investigators will also observe patient clinical status (eczema, infections, use of treatment dose antibiotics, food allergies, etc). Study Design/Setting/Participants: This is a prospective clinical trial treating 9 WAS subjects in the Clinical Translational Research Center (CTRC) with IL-2. Intervention: The investigators propose to subcutaneously administer 0.5 Million Units (MU)/m2 of IL-2 daily to WAS subjects for 5 days. Research treatment will be repeated 2 and 4 months later. Inter-patient dose escalation will be employed to 1 MU/m2 and/or 2 MU/m2 based on safety as the primary endpoint. Study Measures: The investigators will observe safety and tolerability measures and perform assays on subject blood samples prior to and after research treatment to observe improvement in NK cell function.
This research study will investigate the safety and effectiveness of two different dose levels of a new, unapproved drug to be given along with the chemotherapy regimens gemcitabine and carboplatin or gemcitabine and cisplatin prescribed to women for the treatment of ovarian cancer. This experimental drug is called TXA127 and is being tested for effectiveness to see if it will help reduce some of the side effects of the chemotherapy, primarily low blood platelet levels that lead to excess bleeding. This study also intends to test the safety of TXA127 when given as an injection under the skin on a daily basis concurrently with up to 6 cycles of the prescribed chemotherapy.
