Filter by:RATIONALE: Drugs used in chemotherapy, such as bendamustine hydrochloride and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Lenalidomide may stimulate the immune system in different ways and stop cancer cells from growing. Giving bendamustine hydrochloride together with lenalidomide and dexamethasone may kill more cancer cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of bendamustine hydrochloride and lenalidomide when given together with dexamethasone and to see how well they work in treating patients with relapsed multiple myeloma.
The present trial is designed as a phase II study that aims at estimating the efficacy of the combination of bendamustine, bortezomib and dexamethasone in relapsed/refractory multiple myeloma (MM). The response rate, i.e. the rate of the patients achieving a Complete Response or Partial Response at cycle 4, divided by the total intent to treat patient number is chosen as primary efficacy endpoint. The estimation of the efficacy rate is to be based on an explorative pilot study, since immediate embarking on a large-scale comparative efficacy trial would not be acceptable from the point of view of resources. Moreover, this would induce ethical objections, as it does not seem to be justifiable to expose a large number of patients to an experimental approach without sufficient exploratory indications of an improved risk-benefit ratio.
Patient Population: Patients with active myeloma (Stage II/III) that have completed induction therapy and are eligible for an autologous stem cell transplant. Number of Patients: Will treat a total of 32 evaluable patients in a 1:1 randomization of aMILs vs aMILs plus vaccine. An evaluable patient is defined as one which has received the activated MILs and is at least 6 months post-transplant. Study Objectives: Disease response as determined by the Blade' criteria will be the primary endpoint of the trial at one year. Additional study endpoints include progression free survival, parameters of T cell reconstitution, anti-tumor immune responses as well as the effect on osteoclastogenesis and clonogenic myeloma precursor cells.
The purpose of this study is to see if the combination of bendamustine, lenalidomide and dexamethasone will help people with multiple myeloma that has returned after standard treatment or has been resistant to other treatments.
High-dose chemotherapy with melphalan and autologous hematopoietic stem cell transplantation (HSCT) is considered standard treatment for patients with multiple myeloma. While autologous HSCT may induce remission in patients resistant to standard chemotherapy, and has been shown to lead to long-lasting disease control in a subgroup of patients, the procedure is not curative. Given enough time and in the absence of a competing cause of death, all patients eventually relapse after auto-HSCT. The only potentially curative approach currently available in the treatment of multiple myeloma (MM) is stem cell trans-plantation from an allogeneic donor. Allogeneic HSCT eradicates residual myeloma cells through T-cell mediated graft-versus-tumor effects. Allogeneic HSCT is, however, associated with significant risk of graft-versus-host disease and its use is therefore limited to younger patients with high risk dis-ease. Malignant plasma cells in multiple myeloma are also sensitive to natural killer cell lysis. Natural killer cells do not cause graft-versus-host disease, which has led to interest in their therapeutic use in patients with multiple myeloma. We have previously shown that immunomagnetic separation of a highly pure NK cell product from a leukapheresis is possible and that these cells can be expanded up to 100-fold in a GMP-compatible setting. The current study aims to test the tolerability and feasibility of infusions of in vitro expanded haploidentical NK cells for patients after melphalan 200mg/m2 high dose chemotherapy and autologous HSCT in 10 patients. If feasible, the data will provide a basis for further prospective studies.
To determine the efficacy of high-dose topotecan, cyclophosphamide and melphalan in patients with Multiple Myeloma.
The purpose of the study is to evaluate the clinical effectiveness and side effects of the vorinostat, bortezomib, lenalidomide, and dexamethasone investigational combination.
Poor mobilization of hematopoietic progenitors needed to support autologous transplantation is a serious clinical problem. We are investigating the role of plerixafor administered in an at risk population to augment successful stem cell collection. OBJECTIVES To determine if plerixafor when administered on the day prior to planned autologous collection on first mobilization attempt in those with a peripheral blood CD34 ≤ 10X106/L will: - increase the number of patients successfully collected in one day - increase the number of patients successfully mobilized on first collection attempt - is cost neutral within a Canadian setting
The purpose of this study is to monitor such factors as a past history, a previous history of drug use, the degree of response to initial treatment, the frequency of previous therapies, age, Eastern Cooperative Oncology Group (ECOG) performance status, which is used by doctors and researchers to assess how a patient's disease is progressing, assess how the disease affects the daily living abilities of the patient, and determine appropriate treatment and prognosis, before the bortezomib re-treatment, the concomitant drugs that are used for re-treatment and the pattern of treatment in patients with multiple myeloma who were re-treated with injectable bortezomib.
The purpose of this study is to measure the markers related to bone metabolism before and after the use of bortezomib injection in patients with multiple myeloma and to evaluate the effect bortezomib injection has on bone disease.
