Active clinical trials for "Plasmacytoma"

To see if it is possible to use short-duration tacrolimus after a peripheral blood stem cell transplant in certain malignancies that are considered difficult to engraft.

This phase II trial studies how well pomalidomide, ixazomib citrate, and dexamethasone work in treating patients with previously treated multiple myeloma or plasma cell leukemia. Biological therapies, such as pomalidomide and dexamethasone, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Ixazomib citrate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving pomalidomide, ixazomib citrate, and dexamethasone together may be more effective in treating multiple myeloma.

The primary hypothesis of this research study is that patients in remission undergoing myeloablative haploidentical hematopoietic stem cell transplantation (HSCT) on the Thomas Jefferson University (TJU) 2 Step treatment regimen will have a disease-free survival (DFS) rate at 1 year that is the same or better than the historical DFS of patients with similar diagnoses and ages undergoing matched sibling HSCT. Based on a review of the literature a DFS rate of 50% or better at 1 year would meet the criterion for an effective alternative therapy. A DFS rate of 75% or better would imply superior efficacy of the TJU 2 Step approach over T-replete matched sibling HSCT.

This phase II trial investigates whether patients greater than or equal to 65 years of age diagnosed with myeloma or another plasma cell malignancy will have better outcomes with transplant followed by maintenance therapy, as primarily measured by progression-free survival, versus non-transplant approaches.

RATIONALE: Reducing the amount of drugs used to prevent transplant rejection may help a person's body kill tumor cells. Giving biological therapy, such as interferon alfa, which may interfere with the growth of cancer cells, or combination chemotherapy, which uses different ways to stop tumor cells from dividing so they stop growing or die, may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of reducing immunosuppression, and giving interferon alfa and combination chemotherapy, in treating patients who have malignant tumors that develop after organ transplant.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of bryostatin 1 in treating patients with relapsed multiple myeloma.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of decitabine in treating patients with stage III or stage IV melanoma or other advanced cancer that has not responded to previous therapy.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of arsenic trioxide in treating patients who have advanced hematologic cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Some tumors become resistant to chemotherapy drugs. Combining PSC 833 with chemotherapy may reduce resistance to the drug, and allow more tumor cells to be killed. It is not yet known whether combination chemotherapy plus PSC 833 is more effective than combination chemotherapy alone in treating patients with relapsed or refractory multiple myeloma. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy with or without PSC 833 in treating patients with relapsed or refractory multiple myeloma.

RATIONALE: High-dose chemotherapy may destroy the amyloid-producing cells in bone marrow. Peripheral stem cell transplantation PURPOSE: Phase II trial to study the effectiveness of high dose melphalan plus peripheral stem cell transplantation in treating patients who have primary systemic amyloidosis.
