Filter by:This phase I trial is studying the side effects and best dose of GTI-2040 in treating patients with relapsed, refractory, or high-risk acute leukemia, high-grade myelodysplastic syndromes, or refractory or blastic phase chronic myelogenous leukemia. Drugs used in chemotherapy, such as GTI-2040, work in different ways to stop the growth of cancer or abnormal cells, either by killing the cells or by stopping them from dividing.
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Imatinib mesylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. A peripheral stem cell transplant may be able to replace blood-forming cells that were destroyed by chemotherapy. When the healthy stem cells are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Giving combination chemotherapy together with imatinib mesylate and peripheral stem cell transplant may be an effective treatment for acute lymphoblastic leukemia. Nevertheless, in the last few years GIMEMA has pubblished a paper in which 100% of Ph+ ALL patients reach HCR only with Imatinib, without any chemiotherapy. Thus, this treatment will be implemented in patients pertaining to this category.
This phase I trial is studying the side effects and best dose of bevacizumab and cediranib maleate in treating patients with metastatic or unresectable solid tumor, lymphoma, intracranial glioblastoma, gliosarcoma or anaplastic astrocytoma. Monoclonal antibodies, such as bevacizumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Cediranib maleate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Bevacizumab and cediranib maleate may also stop the growth of cancer cells by blocking blood flow to the cancer. Giving bevacizumab together with cediranib maleate may kill more cancer cells.
We would like patients to be in a research study to determine the safety and effectiveness of special cells that may make their own immune system fight their cancer. To do this, we will put a special gene into cancer cells that have been taken from the patients body. This will be done in the laboratory. This gene will make the cells produce interleukin 2 (IL-2), which is a natural substance that may help their immune system kill cancer cells. Additionally, we will stimulate the cancer cells with normal embryonic fibroblasts (cells that develop into normal connective tissues in the body) so that they will make another natural protein called CD40 ligand (CD40L). Studies of cancers in animals suggest IL-2 performs better when mixed with CD40L. Some of these cells will then be put back into the patients body with the goal that they will act like a vaccine and stimulate their immune system to attack the CLL cells. Studies of cancers in animals and in cancer cells that are grown in laboratories suggest that combining substances like IL-2 and CD40L with cancer cells help the body recognize and kill cancer cells. We have already conducted a study similar to this in patients with CLL. In that study, the subjects received about three months of injections (shots). In those subjects we saw some changes in the subject's immune system that might indicate that the modified cells were helping their immune system fight the cancer. However, in most of the subjects this change in the immune system went away after the injections were stopped. In this study we want to see if we can make the change in the immune system last longer by giving more injections over a longer period of time. We hope that this might produce a better response directed at the CLL cells. We will also be looking at the effect on cells called cancer stem cells which grow into the CLL cells we see in the blood. Specifically, this study will allow subjects to receive the injections for up to one year.
RATIONALE: Monoclonal antibodies, such as alemtuzumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. PURPOSE: This phase II trial is studying the side effects and how well alemtuzumab works in treating patients with B-cell chronic lymphocytic leukemia in partial remission or complete remission.
Many patients suffering various malignant and non-malignant diseases need hematopoietic stem cell transplantation from a healthy person. In the majority of cases there is no matched related or unrelated donor. Some researchers have been performed transplantation from semi-matched (haploidentical) related donors with relatively good results. Chinese researchers have been performed this kind of transplantation using CAMPATH-1H and their reports indicates good results. Chinese populations have more homogenous genetic background than Iranians. In this project, we are going to study the feasibility of this method of haploidentical transplantation in Iranian patients.
The aim of this study is to determine the safety, tolerability and dose-limiting toxicities of KW-2478 and to determine the Maximum Tolerated Dose and recommended Phase II dose for patients with relapsed/refractory MM, CLL or B-cell NHL.
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as gemtuzumab ozogamicin, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Tipifarnib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving combination chemotherapy together with gemtuzumab ozogamicin or tipifarnib may kill more cancer cells. PURPOSE: This randomized phase II/III trial is studying different combination chemotherapy regimens to compare how well they work when given with or without gemtuzumab ozogamicin or tipifarnib in treating patients with acute myeloid leukemia or high-risk myelodysplastic syndromes.
RATIONALE: Giving chemotherapy, such as fludarabine, busulfan, and melphalan, before a donor peripheral stem cell transplant or bone marrow transplant helps stop the growth of cancer or abnormal cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a 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 cells from a donor can make an immune response against the body's normal cells. Giving tacrolimus, methotrexate, mycophenolate mofetil, and antithymocyte globulin before and after transplant may stop this from happening. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer or abnormal cells as not belonging in the patient's body and destroy them (graft-versus-tumor effect). Giving an infusion of the donor's white blood cells (donor lymphocyte infusion) may boost this effect. PURPOSE: This phase II trial is studying how well donor stem cell transplant works in treating patients with hematologic cancer or other diseases.
The goal of this clinical research study is to learn if Actonel (risedronate) can help to prevent the development of osteoporosis (brittle and weak bones) caused by the steroid medication used to treat leukemia. The safety of this treatment in patients with ALL or LL will also be studied.
