NCT ID: NCT01295801 Recruiting - Cytopenias Clinical Trials

Vitamin B6 on Relieving Linezolid-associated Cytopenias

Start date: November 2010
Phase: N/A
Study type: Observational

Linezolid is the first approved synthetic oxazolidinone that is active against multidrug-resistant Gram-positive pathogens. Because of its significant efficacy, linezolid is widely used in clinical treatment. However, the side effects of linezolid commonly lead to anemia and thrombocytopenia. This hematological toxic effects limit its prolonged used. The investigators have found that Vitamin B6 application, as a preventive, auxiliary therapy, can relieve anemia and thrombocytopenia. The present study was designed to verify the effects of Vitamin B6 in the prevention of linezolid-associated cytopenias and investigate its mechanism.

NCT ID: NCT01200017 No longer available - Clinical trials for Acute Myeloid Leukemia

Expanded Access Protocol (EAP) Using the CliniMACS® Device for Pediatric Haplocompatible Donor Stem Cell Transplant

Start date: n/a
Phase:
Study type: Expanded Access

This protocol provides expanded access to bone marrow transplants for children who lack a histocompatible (tissue matched) stem cell or bone marrow donor when an alternative donor (unrelated donor or half-matched related donor) is available to donate. In this procedure, some of the blood forming cells (the stem cells) are collected from the blood of a partially human leukocyte antigen (HLA) matched (haploidentical) donor and are transplanted into the patient (the recipient) after administration of a "conditioning regimen". A conditioning regimen consists of chemotherapy and sometimes radiation to the entire body (total body irradiation, or TBI), which is meant to destroy the cancer cells and suppress the recipient's immune system to allow the transplanted cells to take (grow). A major problem after a transplant from an alternative donor is increased risk of Graft-versus-Host Disease (GVHD), which occurs when donor T cells (white blood cells that are involved with the body's immune response) attack other tissues or organs like the skin, liver and intestines of the transplant recipient. In this study, stem cells that are obtained from a partially-matched donor will be highly purified using the investigational CliniMACS® stem cell selection device in an effort to achieve specific T cell target values. The primary aim of the study is to help improve overall survival with haploidentical stem cell transplant in a high risk patient population by limiting the complication of GVHD.

NCT ID: NCT00002303 Completed - HIV Infections Clinical Trials

The Safety and Effectiveness of r-HuEPO in Patients With AIDS or Advanced AIDS-Related Complex (ARC) Who Are Anemic

Start date: n/a
Phase: N/A
Study type: Interventional

To determine the safety and efficacy of erythropoietin administered to patients with AIDS or advanced AIDS related complex ARC and anemia.

NCT ID: NCT00002302 Completed - HIV Infections Clinical Trials

The Safety and Effectiveness of r-HuEPO in Patients With AIDS and Anemia Caused by AIDS and Treatment With AZT

Start date: n/a
Phase: N/A
Study type: Interventional

To determine the safety and efficacy of erythropoietin administered subcutaneously to AIDS patients with anemia secondary to their disease and/or concomitant zidovudine (AZT) therapy. Efficacy will be assessed by correction of anemia and decrease in transfusion requirements.

NCT ID: NCT00002281 Completed - HIV Infections Clinical Trials

A Study of Granulocyte Colony-Stimulating Factor Plus Recombinant Erythropoietin Plus Zidovudine in Patients With AIDS or AIDS-Related Complex

Start date: n/a
Phase: N/A
Study type: Interventional

To evaluate the safety, tolerance and biological activity of filgrastim (granulocyte colony-stimulating factor; G-CSF) given by daily subcutaneous (SC) injection prior to and concomitantly with erythropoietin (EPO) and zidovudine (AZT) in patients with AIDS or severe AIDS related complex (ARC). To evaluate the safety, tolerance, and biological activity of EPO given 3 times weekly by SC injection concomitantly with G-CSF and prior to and concomitantly with AZT in patients with AIDS or severe ARC. To study the safety and tolerance of 3 dose levels of AZT given to patients with AIDS or severe ARC concomitantly treated with G-CSF and EPO. To study the effect of G-CSF alone and in combination with EPO on HIV replication in vivo as measured by circulating HIV p24 antigen, plasma HIV viremia and semiquantitative HIV cocultures.

NCT ID: NCT00002263 Completed - HIV Infections Clinical Trials

A Pilot Study to Evaluate the Effects of Subcutaneously Administered Recombinant Human Granulocyte-Macrophage Colony Stimulating Factor in Pediatric HIV-Infected Patients With Neutropenia Secondary to Azidothymidine

Start date: n/a
Phase: N/A
Study type: Interventional

To assess the safety and efficacy of subcutaneous sargramostim ( granulocyte-macrophage colony-stimulating factor; GM-CSF ) in increasing and maintaining the granulocyte count in HIV-infected children who have developed granulocytopenia as a result of continuous intravenous ( CIV ) zidovudine ( AZT ). To assess the short-term and long-term effects of concomitant GM-CSF on other hematologic parameters. To assess the potential therapeutic benefit of concomitant GM-CSF and AZT on the natural history of HIV infection and associated infectious complications.

NCT ID: NCT00002258 Completed - HIV Infections Clinical Trials

A Phase I, Open Label Trial to Evaluate the Safety, Tolerance and Biological Effects of SDZ ILE-964 (Recombinant Human Interleukin-3, RhIL-3) in HIV Infected Patients With Cytopenia

Start date: n/a
Phase: Phase 1
Study type: Interventional

To determine the safety, tolerability and maximum tolerated dose of SDZ ILE 964 administered by daily subcutaneous injections in patients infected with human immunodeficiency virus (HIV) who have cytopenias (low blood cell counts). To obtain information about the biologic effects of SDZ ILE 964 administration in improving blood counts in HIV-infected patients. To obtain information about the effects of SDZ ILE-964 administration on both parameters of HIV replication and on residual immunologic function.

NCT ID: NCT00002126 Completed - HIV Infections Clinical Trials
