Active clinical trials for "Neoplasms, Plasma Cell"

BEAM regimen (BCNU, etoposide, cytarabine, and melphalan) is the most commonly used conditioning regimen for relapsed/refractory lymphoma patients needing autologous stem cell transplantation. Since these components are all effective in myeloma and bortezomib has shown promising results in the transplant setting, here the investigators propose a phase II study to investigate the combination of bortezomib and BEAM as a new conditioning regimen for patients who relapse or progress after the first autologous transplantation and for whom a second autologous transplant is considered.

This is a phase 2, multicenter, open label, nonrandomized study for patients with MM who will receive treatment with a SC bortezomib-containing combination regimen that does not contain thalidomide or vincristine. The patients will be required to have received a prior IV bortezomib containing combination regimen that did not contain thalidomide or vincristine and that differs from the SC bortezomib-containing one. In between the time that the patient received the IV bortezomib-based combination regimen and enrollment onto this study, patients may have received other non-bortezomib-based regimens as long as these treatments did not contain thalidomide or vincristine. This study will enroll patients who have relapsed or have become refractory to their prior IV-administered bortezomib-containing combination regimen as demonstrated by progressive disease while on or following that regimen. Patients must have received 4 doses of a minimum of 1.0 mg/m2 of bortezomib administered IV in no more than 4 weeks per cycle. Patients must have received at least one cycle meeting this definition and have shown progressive disease to be considered eligible. Patients who have relapsed or have become refractory to their most recent IV bortezomib-containing combination regimen are eligible regardless of when they received that regimen, as long as they meet the above criteria. The study will consist of a screening period, followed by up to eight open label treatment cycles, a final assessment to occur 28 days after the end of the last treatment cycle, and a follow-up period.

The study hypothesis is that lenalidomide and romidepsin (and dexamethasone for patients with myeloma) will have an acceptable toxicity profile and that in combination will have sufficient activity in the target population (including those previously refractory to HDACi monotherapy) to warrant further investigation.

Based on the pre-clinical data the investigators hypothesize that G-CSF treatment in patients with multiple myeloma will generate a 'hostile' bone marrow microenvironment for myeloma cells, depriving them of key support signals and rendering them more sensitive to chemotherapy. The investigators therefore propose to do an initial pilot study 1) to explore the safety of the combination of G-CSF and bortezomib-, carfilzomib-, or IMID-based treatment regimens in patients with bortezomib-, carfilzomib-, or IMID-refractory myeloma and 2) to generate correlative data for a subsequent larger study looking at the combination.

Eltrombopag is a compound that may help stimulate the production of platelets. This drug has been used in treatment of low platelet counts caused by a disorder called idiopathic thrombocytopenic purpura and information from those other research studies suggests that Eltrombopag may help to maintain platelet counts in patients with relapsed multiple myeloma in this research study. In this research study,the investigators are trying to determine if Eltrombopag is effective in maintaining platelet counts in patients who are being treated for relapsed multiple myeloma.

This study evaluated the efficacy and safety of Avastin (bevacizumab, 5 mg/kg intravenously every 2 weeks) in patients with multiple myeloma, relapsed/refractory after at least 2 lines of prior therapy.

This is a multicenter, randomized, blinded, 2-arm phase IIb trial that will compare the efficacy and safety of Lenalidomide maintenance after Bortezomib/Melphalan/Prednison (VMP) induction to VMP without maintenance (Placebo). In addition the trial will assess the treatment of Revlimid/low dose Dexamethasone (Rd) as Salvage after VMP without sufficient response (less than PR) in an observational arm. Key eligibility criteria include patients with newly diagnosed multiple myeloma and who are 65 years of age or older or are not candidates for high-dose chemotherapy and autologous stem cell transplantation. Patients with poor performance status or serious coexistent medical conditions will be excluded from this study. After registration all patients receive 6 cycles VMP (modified according to Mateos et al.). Patients who receive at least a PR and completed VMP can be randomized to either Lenalidomide 10 mg/d continuously maintenance or to placebo. Randomization will be stratified according to the quality of response after VMP induction (PR vs. VGPR + stringent complete remission [sCR] + CR). Patients that are not able to complete VMP due to toxicity but reached at least a PR after a minimum of four cycles of therapy should immediately proceed to randomization. Blinded phase continues until progression or end of study. After unblinding, patients who received placebo should be treated with Rd. Patients that do not reach PR after induction with VMP or are progressive during treatment with VMP should not be randomized, but switched to the observation arm and treated with Rd immediately. The study treatment ends with the confirmed progression on maintenance treatment (Lenalidomide or placebo) for patients that reached PR with induction treatment, or with the confirmed progression on second-line therapy with Revlimid® and Dexamethasone for patients that did not reach PR on induction treatment. All patients will be followed up every 3 months after end of study treatment, until end of study. The study ends two years after Last Patient In (i.e. randomization for maintenance) if sufficient events for the primary endpoint were received, but not later than 8 years after trial initiation (whatever comes first).

This study uses a drug called dasatinib to produce an anti-cancer effect called large granular lymphocyte cellular expansion. Large granular lymphocytes are blood cells known as natural killer cells that remove cancer cells. Researchers think that dasatinib may cause large granular lymphocyte expansion to happen in patients who have received a blood stem cell transplant (SCT) between 3 to 15 months after the blood SCT. In this research study, researchers want to find how well dasatinib can be tolerated, the best dose to take of dasatinib and to estimate how often large granular lymphocytic cellular expansion happens at the best dose of dasatinib.

This study will examine whether 240 µg/kg plerixafor given alone for up to 4 days is safe and well tolerated in multiple myeloma (MM) patients. In addition, this study determines if plerixafor alone can be used to mobilize peripheral blood progenitor cells (PBPCs) for transplantation in MM patients. The minimum number of CD34+ cells to collect is 2*10^6 CD34+ cells/kg and the target is ≧4*10^6 CD34+ cells/kg. Success of transplant engraftment will be measured by the number of days to polymorphonuclear leukocytes (PMN) and platelet (PLT) engraftment. Durability of transplant will be assessed for a minimum of one year.

The purpose of this research study is to test the safety and effectiveness of replacing vincristine with a drug called bortezomib (also known as "Velcade"or PS341) in the standard therapy vincristine, doxorubicin (not limited to, but formerly referred to under the tradename Adriamycin) and dexamethasone (VAD) in patients with multiple myeloma. Multiple Myeloma is the second most common cancer of the blood. Bortezomib is the first approved cancer treatment in a new class of medicines called proteasome inhibitors. It disrupts the cell cycle of the cell, affecting numerous biologic pathways, including those related to growth and survival of cancer cells. The treatment will be used as second line treatment, which means either the disease has returned after a period of improvement (relapse) or the disease did not respond to the initial treatment (refractory). Patients will receive either bortezomib (PS341), doxorubicin (Adriamycin) and dexamethasone (PAD) or the VAD standard therapy.
