Active clinical trials for "Neoplasms, Plasma Cell"

This is a compassionate use, open-label, IND study for the purpose of providing carfilzomib to patients with relapsed or resistant refractory multiple myeloma.

To provide pomalidomide access to relapsed/refractory multiple myeloma subjects with a likelihood of benefit from the pomalidomide treatment while the medication is not commercially available

The purpose of this study is to give patients who have had 4 or more prior lines of therapy for multiple myeloma access to VELCADE. The study is for patients who are not eligible for other clinical trials with VELCADE and for who VELCADE would otherwise not be available.

Carfilzomib is approved in Turkey for the treatment of adult relapsed multiple myeloma patients who have received at least one prior treatment. It is approved for use in combination with lenalidomide and dexamethasone (KRd) in and with dexamethasone alone (Kd). The purpose of this study is to describe contemporary, real-world patterns of patient characteristics, clinical disease presentation, prior therapeutic regimen chosen, and clinical outcomes in participants with relapsed/refractory (R/R) multiple myeloma (MM) who receive Carfilzomib combination treatment. Real-world evidence is crucial to understand how carfilzomib-based regimens are used in practice and in relation to local prescribing information. This is a prospective, non-interventional, observational study. The study population will include patients with relapsed/refractory MM who have received 1 to 3 prior lines of therapy with documented data in the medical record regarding diagnosis (month and year), the regimens used in 1st, 2nd, and 3rd line as applicable, whether stem cell transplant was part of 1st, 2nd, and 3rd line of therapy at participating clinical sites in Turkey.

The FULIMA study is a two-center study at Odense University Hospital and Vejle Hospital, Denmark. The primary objective is to identify the optimal imaging technique for studies in multiple myeloma with focus on PET/CT and MRI. By combining early (1 hour) and late (3 hours) 18F-2-fluoro-2-deoxy-D- fluorodeoxyglucose(18F-FDG)-PET/CT scans the investigators expect to see increased uptake of radioactive tracer and thus an improved ability to identify malignant tissue. A second tracer 18F-natrium-fluoride is used to explore early signs of bone remodeling. By using new software (ROVER) for interpreting PET data the investigators expect to obtain a quantitative measurement of total disease burden with less risk of misinterpretation of data. Diffusion weighted MRI (DWI) is a new MRI technique which, like PET/CT, makes it possible quantitatively to calculate the overall disease activity and to give an early evaluation of response to chemotherapy. The study examines DWI for development and standardization. To validate imaging findings and to explore the pathogenetic heterogeneity of multiple myeloma, the investigators perform CT guided biopsies from PET/ DWI positive sites. Pathoanatomical and immunohistochemical findings and gene expression data from positive sites are compared to random bone marrow. The question is whether disease heterogeneity may explain the lack of FDG uptake in bone marrow in some patients? To the extent that the FULIMA study produces useful data, the defined and standardized imaging techniques will form the basis of a larger prospective study at national level in Denmark.

Whole body MRI with diffusion weighted imaging is a useful imaging tool staging and diagnosis therapy monitoring All patients will be scanned before and during treatment. The findings on diffusion weighted imaging will be correlated to the golden standard (computer tomography and MRI (T1 and STIR)).

The study is an italian multicentric and will be conducted in 20 centers. The aim of this study is to evaluate poor mobilizer (PM) rate in newly diagnosed MM patients who are mobilized with cyclophosphamide and G-CSF and plerixafor on demand. Plerixafor is a specific reversible inhibitor of the chemokine receptor CXCR4 and prevents the binding of its ligand stromal cell derived factor SDF-1α also known as CXCL12, thereby releasing hematopoietic stem cells into the circulation.

Multiple myeloma is a disease that causes increased bone fragility which is often revealed or complicated by vertebral fractures. Invasion of bone marrow by tumor plasma cells leads to bone destruction and reduced fat fraction. The main objective is to assess the correlation between vertebral bone marrow fat fraction and bone fragility represented by a severity score of vertebral fractures. The secondary objective is to assess the correlation with clinical and biological prognostic factors and scores..

Objectives: The overall objective of this project is to identify risk factors associated with the development of multiple myeloma (MM) by integrating epidemiologic, clinical and molecular information. We plan to invite MDACC patients with MM, as well as controls, to participate in this investigative case-control study. Controls will be selected from friends and spouses who accompany patients to the various MDACC clinics and will be matched to the cases on age (±5 years), gender, and ethnicity. We will obtain demographic, risk factor and clinical information along with a blood and buccal sample from all cases and controls. This study could have implications for prevention and subsequent reduction in the incidence of multiple myeloma. Collecting blood and buccal samples will allow us to study the role genetic susceptibility plays in MM risk. The specific aims are: To enroll and obtain, through self-administered questionnaires, risk factor information on all study participants to develop detailed demographic, epidemiologic, and behavioral profiles. This study will accrue 250 MM patients from MDACC and 250 healthy controls selected from friends and spouses who accompany patients to the MDACC clinics. Blood (25 ml) and buccal samples will be collected from all participants. To identify risk factors associated with MM by integrating epidemiological, clinical and molecular information using a case-control approach. To evaluate constitutional markers of genetic susceptibility as predictors of MM risk. Gene-environment interactions will be explored.

Multiple myeloma (MM) is a malignancy of plasma cells engaging in monoclonal immunoglobulin production. A strong presumption was established between exposure to pesticides and the risk of MM. The French West Indies departments of Guadeloupe and Martinique are characterized by a wide use of pesticides related to bananas plantation, particularly chlordecone which has been classified by IARC as possibly carcinogenic and has recognized hormonal properties (endocrine disruptor). The objective of this study is to measure the association between exposure to pesticide and other environmental factors in the occurrence of MM in Guadeloupe and Martinique and to estimate the proportion of cases of MM attributable to pesticide exposure. Genetic susceptibility markers and their links to environmental factors will be subsequently studies from blood samples collection.
