NCT ID: NCT01727232 Completed - Clinical trials for Primary Immune Thrombocytopenia

Efficacy and Safety of Rituximab Given at Fixed Dose (1000 mg on Days 1 and 15) Compared to the Standard Regimen in Adult's Immune Thrombocytopenia

Start date: January 2007
Phase: N/A
Study type: Observational

The aim of this large French multicentric retrospective study was to compare the efficacy and safety of two (the standard and the Rheumatoid arthritis) rituximab regimens in adult's immune thrombocytopenia .

NCT ID: NCT01692366 Completed - Myelofibrosis Clinical Trials

Phase 2 Study in Japanese Patients With Intermediate-2 or High Risk Primary Myelofibrosis, Post-Polycythemia Vera Myelofibrosis, Post-Essential Thrombocythemia Myelofibrosis With Splenomegaly

Start date: November 2012
Phase: Phase 2
Study type: Interventional

Primary Objective: - To evaluate the efficacy of daily oral doses of 300 mg, 400 mg, and 500 mg SAR302503 and combined for the response rate defined with the ≥35% reduction of spleen volume as determined by magnetic resonance imaging (MRI or computed tomography scan [CT] in patients with contraindications for MRI). Secondary Objectives: - To evaluate the safety of SAR302503 for both pooled (300, 400, and 500mg) and individual doses population. - To evaluate the pharmacokinetics (PK) of SAR302503 after single and repeat-dose. - To evaluate the effect on Myelofibrosis (MF)-associated symptoms (Key MF symptoms) as measured by the modified Myelofibrosis Symptom Assessment Form (MFSAF). - To evaluate the durability of splenic response. - To evaluate the effect of SAR302503 on bone marrow with regard to changes on reticulin fibrosis.

NCT ID: NCT01672151 Completed - Clinical trials for Immune Thrombocytopenic Purpura

Efficacy of Rapamycin Therapy With Chronic Immune Thrombocytopenia

ITP
Start date: November 2011
Phase: N/A
Study type: Observational

The aim of our study is to evaluate the efficacy of rapamycin with Refractory Immune Thrombocytopenic Purpura (RITP) and explore the further mechanism.

NCT ID: NCT01668615 Completed - Clinical trials for Immune Thrombocytopenic Purpura

Efficacy of Immunomudulatory Therapy With All-trans Retinoid Acid for Adults With Chronic Immune Thrombocytopenia

ITP
Start date: January 2011
Phase: N/A
Study type: Observational

The purpose of this study is to determine whether All-trans retinoic acid (ATRA) are effective in the treatment of refractory idiopathic thrombocytopenic purpura (RITP).

NCT ID: NCT01668173 Terminated - Clinical trials for Myeloproliferative Neoplasms

HSP90 Inhibitor, AUY922, in Patients With Primary Myelofibrosis (PMF), Post-Polycythemia Vera Myelofibrosis (Post-PV MF), Post-Essential Thrombocythemia Myelofibrosis (Post-ET MF), and Refractory PV/ET

Start date: August 2012
Phase: Phase 2
Study type: Interventional

The purpose of this study is to test a new drug called AUY922. AUY922 is not FDA-approved. AUY922 is a new kind of drug that attacks a protein called HSP90. HSP90 is found in both normal and cancer cells, but the investigators think it is more important in cancer cells. This study will see if AUY922 helps people with myelofibrosis, essential thrombocythemia and polycythemia vera. This study will also see if AUY922 is safe in people with myelofibrosis, essential thrombocythemia and polycythemia vera. It will find out what effects, good and/or bad, AUY922 has on the patient and the disease. The researchers hope that this study will help them to find better treatments for primary myelofibrosis, essential thrombocythemia and polycythemia vera.

NCT ID: NCT01666795 Completed - Clinical trials for Immune Thrombocytopenia (ITP)

Autoantibody Specificity and Response to IVIG in ITP

Start date: February 2005
Phase: N/A
Study type: Observational

The objective of this human study was to evaluate the association between the specificity of anti-platelet autoantibodies and response to IVIG treatment.

NCT ID: NCT01654848 Completed - Clinical trials for Liver Transplantation

Heparin-induced Thrombocytopenia (HIT II) in Liver Transplant Recipients

HITOLT
Start date: January 2010
Phase: N/A
Study type: Observational

In a prospective observational study the incidence of Heparin-induced Thrombocytopenia (HIT) Type 2 after orthotopic liver transplantation, associated factors, and hemostaseological findings in thrombocytes and anti-body patterns is going to be investigated.

NCT ID: NCT01618734 Completed - Clinical trials for Immune Thrombocytopenia

Eltrombopag and Romiplostim Used Alternatively in Patients With Immune Thrombopenia (ITP): Efficacy and Safety.

Start date: January 2012
Phase: N/A
Study type: Observational

TPO-r Switch is a retrospective study of the patients affected by Immune Thrombopenia (ITP) who received alternatively romiplostim and eltrombopag.

NCT ID: NCT01598168 Terminated - Clinical trials for Heparin-induced Thrombocytopenia

Rivaroxaban for Treatment of Patients With Suspected or Confirmed Heparin-Induced Thrombocytopenia

Start date: January 2013
Phase: Phase 3
Study type: Interventional

Heparin is an anticoagulant (blood thinner) that is commonly used to treat patients with heart attacks and patients with blood clots in their legs or lungs (venous thrombosis). Some patients develop an allergic reaction to heparin, a condition called heparin-induced thrombocytopenia (HIT). HIT makes blood clot, which is the opposite of what heparin was designed to do. These blood clots can lead to heart attacks, strokes, limb amputations, and death. The objective of this 200 patient study is to determine if a new blood thinner called rivaroxaban (Xarelto) can be used to treat HIT. Rivaroxaban can be taken by mouth, does not require blood testing, and had a low risk of bleeding when it was used to treat blood clots in other clinical trials. If this study shows that rivaroxaban can be used to treat HIT, there will be two very important benefits. For patients with HIT, the benefit will be having a safe, and easy-to-use drug to protect them from developing further life or limb-threatening blood clots. For the Canadian health care system, the benefit will be having a drug that is much less expensive than the drugs currently used to treat HIT.

NCT ID: NCT01588015 Completed - Clinical trials for Chronic Myelomonocytic Leukemia

Vaccine Therapy in Preventing Cytomegalovirus Infection in Patients With Hematological Malignancies Undergoing Donor Stem Cell Transplant

Start date: October 29, 2012
Phase: Phase 1
Study type: Interventional

This randomized phase I trial studies the side effects of vaccine therapy in preventing cytomegalovirus (CMV) infection in patients with hematological malignancies undergoing donor stem cell transplant. Vaccines made from a tetanus-CMV peptide or antigen may help the body build an effective immune response and prevent or delay the recurrence of CMV infection in patients undergoing donor stem cell transplant for hematological malignancies.
