Filter by:The purpose of this study is to determine the safety and the maximum tolerated dose (MTD) of GRN163L when administered to patients with refractory or relapsed multiple myeloma.
The purpose of the study is to determine the safety and effectiveness of providing 2-methoxyestradiol to patients with plateau phase or relapsed multiple myeloma. Information regarding trough 2ME2 levels will also be collected.
This study uses a new investigational (not yet approved by the FDA for widespread use) drug called ZIO-101, an organic arsenical. You must be diagnosed to have relapsed/refractory leukemia or lymphoma (blood cancer) and have tried other standard therapies. This study is designed to determine whether ZIO-101 may be given safely. The study will also test whether ZIO-101 helps to treat blood cancer. We anticipate that approximately 22 to 35 patients will take part in this study. Arsenic has been used as a medicinal agent for centuries in many different cultures. Most recently in the United States, an inorganic arsenic compound was approved by the FDA for the treatment of patients with relapsed acute promyelocytic leukemia (APL). However, use of inorganic arsenic is limited by a narrow range of activity and systemic toxicity, most notably of the cardiac system. ZIO-101 is an organic arsenic derivative. In vitro testing in both the National Cancer Institute (NCI) cancer cell panel and in vivo testing in a leukemia animal model demonstrated substantial activity of SGLU against hematologic cancers. In vitro testing of SGLU using the NCI human cancer cell panel also detected activity against lung, colon and brain cancers, melanoma, and ovary and kidney cancers. Moderate activity was seen against breast and prostate cancers cells. Data suggest that organic arsenic generates reactive oxygen species in the cells to induce apoptosis and cell cycle arrest.
RATIONALE: Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus, sirolimus, antithymocyte globulin, and methotrexate before and after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well sirolimus, tacrolimus, and antithymocyte globulin work in preventing graft-versus-host disease in patients undergoing a donor stem cell transplant for hematological cancer .
The purpose of this phase II study is to assess the toxicity and efficacy of sequentially administered high dose chemotherapy followed by autologous stem cell rescue in the treatment of multiple myeloma. Prior studies have shown that dose-intensified melphalan can produce higher response rates and complete remission in some patients. Over the past several years, multiple phase II studies utilizing high dose chemotherapy or high dose chemo-radiotherapy with autologous marrow or peripheral blood stem cell rescue have demonstrated improved response rates and survival rates compared to historical controls. Recently a prospective randomized trial has demonstrated improved response rates, response duration and overall survival utilizing high dose therapy with autologous bone marrow support compared to standard chemotherapy. The primary cause of failure is relapse and it is unclear how many, if any, patients are cured by this approach. Based on observations of efficacy in Hodgkin's Disease, Non-Hodgkin's Lymphoma, and breast cancer, an approach utilizing sequential high dose chemotherapy in multiple myeloma was developed. This protocol tests the sequential regimen in multiple myeloma patients who have responded to a standard dose chemotherapy regimen prior to enrollment.
Patients will receive Bortezomib, Dexamethasone, and Doxorubicin in 21 day cycles a total of 4 to 8 times (based on response to the treatment). Patients will also receive acetyl-L-carnitine (ALCAR) daily.
This experimental study evaluates the effects of a series of intensive drug regimens as initial treatment for Multiple Myeloma followed by 2 bone marrow transplantations 4─6 months apart in support of high─dose Melphalan, followed by Interferon treatment indefinitely.
The purpose of this research study is to define the time a molecule in the participants bones called NTX begins to rise after receiving treatment with bisphosphonates. NTX is measured in the urine to determine the rate of bone breakdown. Tracking this marker may help identify a more optimal dosing schedule of bisphosphonate therapy. Bisphosphonate drugs like zoledronic acid, which will be used in this study, are used to reduce pain and bone fractures in people with multiple myeloma. There is some laboratory data to suggest that they may work against myeloma. Participants will have already undergone bisphosphonate therapy and may have received zoledronic acid as treatment. Typically these agents are continued indefinitely. Due to concerns of their long-term side effects we are looking at alternate strategies for reducing the frequency of these agents.
This study is being done in an attempt to improve the remission rate and the survival time for subjects with high-risk myeloma. It is hoped that by giving higher doses of commonly used chemotherapy drugs and by giving courses closer together (before the myeloma comes back or gets worse), subjects in this study will have better outcomes.
The purpose of the study was to determine the effect of Epoetin alfa therapy (short term versus long term) with and without a home-based individualized exercise program that incorporated aerobic and strength resistance training for patients being treated with high-dose chemotherapy and autologous peripheral bloodstem cell transplantation (PBSC T) for multiple myeloma. The endpoints for the study included the number of attempts at and total number of days of stem cell collection, number of RBC and platelet transfusions during the transplantation period, time-to-recovery after transplantation, and response to intensive therapy for multiple myeloma.
