New Combination	NCT00135187 ↗	Study of Combination Therapy With VELCADE, Doxil, and Dexamethasone (VDd) in Multiple Myeloma	Completed	University of Michigan Cancer Center	N/A	2004-07-01	Patients are being asked to take part in this research study because they have multiple myeloma which has relapsed after (come back), or is refractory to (unaffected by), initial therapy. For patients who have relapsed or are refractory to therapy, there is no agreed upon standard treatment. Treatment options include chemotherapy and, for some patients, bone marrow transplants. None of the available treatments are curative and investigators are continually looking for more effective treatments. This study involves treatment with a new combination of standard drugs: VELCADE, Doxil, and Dexamethasone. Preliminary results from a study using a combination of VELCADE with Doxil showed high response rates (disease reduction). Two other studies showed that an addition of Dexamethasone to VELCADE in patients not responding to VELCADE alone improved response rate. The proposed combination of all three drugs may improve efficacy and response. VELCADE is approved by the Food and Drug Administration (FDA) for use in multiple myeloma. Doxil is not approved for use in multiple myeloma but is an approved drug for use in patients with some other cancers. Several published clinical trials provide evidence that Doxil is an active agent in multiple myeloma and it is used in treatment combinations for multiple myeloma in general practice. Dexamethasone is approved for use in multiple myeloma. The combination of all three drugs is experimental (not FDA approved). The goals of this study are to determine if this new combination therapy with VELCADE, Doxil and Dexamethasone is an effective treatment, and also to determine the side effects that occur when this combination treatment is given.

New Formulation	NCT01337505 ↗	Safety and Maximum Tolerated Dose (MTD) Study of INNO-206 in Subjects With Advanced Solid Tumors	Completed	CytRx	Phase 1	2011-04-01	This is a phase 1b open-label study evaluating the preliminary safety and maximum tolerated dose of a new formulation of INNO-206 administered at doses of 230 mg/m2, 350 mg/m2 and 450 mg/m2 (165, 260, 325 mg/m2 doxorubicin equivalents, respectively) through intravenous infusion on Day 1 every 21 days for up to 6 cycles.
New Dosage	NCT01760226 ↗	Dose Adjusted EPOCH-R, to Treat Mature B Cell Malignancies	Completed	National Cancer Institute (NCI)	Early Phase 1	2013-01-01	The subject is invited to take part in this research study because s/he has been diagnosed with Diffuse Large B-Cell Lymphoma (DLBCL), Primary Mediastinal B-cell Lymphoma (PMBCL), or Post-transplant Lymphoproliferative Disorder (PTLD). In an attempt to improve cure rates while reducing harmful effects from drugs, oncologists are developing new treatment protocols. One such protocol, entitled dose-adjusted EPOCH-R, utilizes two major new strategies. First, the treatment approach utilizes continuous infusion of chemotherapy over four days, instead of being administered over minutes or hours. Secondly, the doses of some medications involved are increased or decreased based on how the drugs affect the subject's ability to produce blood cells, which is used as a measure of how rapidly the body is processing drugs. Using this approach in adults, researchers have shown improved cure rates in these cancers. Additionally, the harmful effects experienced by patients has been mild, with mucositis, severe infections, and tumor lysis syndrome occurring rarely. However, this new dosing method has never been used in children, and the effectiveness and side effects of this new method are unknown in children. The purpose of this study is to look at the safety of dose-adjusted EPOCH-R in the treatment of children with mature B-cell cancers, and to see if we can maintain cure rates (as has been shown in adults). This study represents the first trial of dose-adjusted EPOCH-R in children.

HIV-infected patients are at increased risk for developing intermediate and high-grade NHL. While combination chemotherapy for aggressive B-cell NHL in the absence of immunodeficiency is highly effective, the outcome of therapy for patients with AIDS-associated NHL has been disappointing. Treatment is frequently complicated by the occurrence of multiple opportunistic infections, as well as the presence of poor bone marrow reserve, making the administration of standard doses of chemotherapy difficult. A recent study was completed using a low-dose modification of the standard mBACOD (cyclophosphamide, doxorubicin, vincristine, bleomycin, dexamethasone, methotrexate ) treatment. A 46 percent response rate was observed in patients treated with this combination of chemotherapeutic agents, with a number of durable remissions and reduced toxicity when compared to previous experience with more standard treatments. A subsequent study showed similar effectiveness using a lower dose of methotrexate administered on day 15. It is hoped that the use of sargramostim (granulocyte-macrophage colony-stimulating factor; GM-CSF) will improve bone marrow function and allow for administration of a higher dose of chemotherapy.
