Active clinical trials for "Neoplasms, Plasma Cell"

This is a long-term observational study of patients that were treated with at least 1 dose of study treatment (plerixafor or placebo) in the AMD3100-3102 protocol (NCT00103662).

In multiple myeloma "cancer stem" cells can be defined and quantified with flow cytometry. More, these cells can be related to treatment response.

Study aiming at testing the positive predictive value of the Hevylite blood test in detecting minimal residual disease in myeloma compared to an invasive method requiring bone marrow sample by multi-parametric flow cytometry

Based on our previous observations, here the investigator plans to further investigate eNAMPT in MM biology and to establish its role in disease progression where EMT acquisition represents an hallmark of cancers. Results deriving from proposal would hopefully identify novel biological vulnerabilities of such malignancy and an innovative biomarker for disease progression monitoring as well.

Treatment options for multiple myeloma have increased significantly over the last years with the approval of immunomodulatory drugs (IMiDs) and proteasome inhibitors (PIs). These therapies have markedly improved overall survival for these patients to a median of 5-7 years. Due to the advanced age, the myeloma patient collective has a high prevalence of pre-existing cardiovascular comorbidities. In addition, the primary disease process contributes to cardiovascular complications. With the beginning of anti-tumor therapy, an increased incidence of cardiovascular complications in myeloma patients can be determined. This includes hypertension, left ventricular dysfunction, heart failure and both arterial and venous thromboembolic events. The detailed mechanism by which proteasome inhibitors and immunomodulatory agents lead to increased cardiovascular events is not established at this time. Endothelial dysfunction, as a possible mechanism of cardiovascular toxicity, is difficult to assess. Flow-mediated dilation (FMD) is an noninvasive method to measure endothelial function by assessing the change in the vasodilatative reserve of the brachial artery. Several independent recent investigations implicate that vascular (endothelial) dysfunction precedes hypertension and heart failure. This has been related to a reduced level of metabolites of the l-arginine-nitric oxide (NO) signaling pathway. Hypothesis: Anti-myeloma therapy exert vascular toxicity by limiting endothelial function. Endothelial function, assessed by the change in the vasodilatative reserve of the brachial artery (flow-mediated dilation = FMD) decreases after myeloma therapy. Patients with multiple myeloma have a limited endothelial function compared to a healthy control group. A total of 40 myeloma patients will be examined. Measurements will be taken at baseline, 1 month and 6 month after myeloma therapy. Patients should not have received chemotherapy for at least 3 months. Furthermore a healthy sex- and age-matched control group will be examined.

The purpose of this study is to examine how patients with multiple myeloma (MM) have been impacted by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. The study will use a questionnaire to further understand how patients are being affected and gather information in order to track the long-term effects of the coronavirus. The scope of the questionnaire will include, COVID-19 diagnosis and treatment, changes in myeloma treatment and care, clinical trial familiarity, health and fitness, and quality of life. This questionnaire is a follow-on to the "MM and COVID-19" questionnaire.

This research is being done to see if the immune (defense) system of people with Multiple Myeloma and Waldenstrom's Macroglobulinemia reacts to the COVID-19 vaccine.

Autologous stem cell transplantation remains the gold standard of treatment for newly diagnosed patients under the age of 65. Even though it is also regularly performed above the age of 65, there are very few data in this patient population. The investigators will capture safety and efficacy data in that setting.

Twenty four patients with multiple myeloma will be randomized to either AM group (administration of lenograstim at 8 am) or PM group (administration of lenograstim at 6 am ). Apheresis of hematopoietic stem cell will start at 10 am on D5 in AM group and at 8 am on D4 in PM group, respectively. Pharmacokinetic data of lenograstim will be correlated with pharmacodynamic data of CD34+ cell count, absolute neutrophil cell count and hematopoeitic progenitor cell count. In addition, the yield of stem cell collection between two arms will be analyzed.

Despite the significantly higher complete remission rates and improved survival achieved over the last decade，multiple myeloma (MM) patients continue to relapse due to persistence of minimal residual disease (MRD). Currently, numerous studies have evaluated the prognostic value of MRD by detecting immunophenotypic and immunoglobulin (Ig) gene rearrangements from bone marrow aspiration samples. Here the investigators intend to study the clinical utility of Ultrasensitive Chromosomal Aneuploidy Detection (UCAD) as an MRD assay, which is based on plasma cell-free DNA(cfDNA) low-coverage whole-genome sequencing. UCAD is non-invasive and applicable for tumors with high heterogeneity and extramedullary invasions.
