Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

The disease, disorder, syndrome, illness, or injury that is being studied.
Study the biomarkers recorded on plasma cells and normal leukocytes including T lymphocytes (naïve, effectors and memories), B lymphocytes, Treg, NK, monocytes as well as their activation markers (CD25, PD-1) in paired bone marrow and blood samples. Validate the pre-analytical stability of the samples between T0 (< 4 hours after sampling) and T0 + 72 hours. Secondary objectives: Validate the strategy of quantification of receptors on plasma cells by direct labeling in flow cytometry. Validate a new method for measuring receptor occupancy by a drug. Validate the pre-analytical stability of the absolute quantitative expression of the receptors and the specific marker CD138 on samples between T0 (< 4 hours after sampling) and T0 + 72 hours. The study will be enrolling 20 patients.
