Groups in this outcome

Stem Cell Collection Without In-vivo Purging With Bortezomib

Standard of Care Stem cell collection without in-vivo purging with Bortezomib. Standard of Care drugs Granulocyte colony-stimulating factor (G-CSF) +/- Mozobil (the latter if needed). NOTE: Multiparametric Flow Cytometry to be performed on samples for BOTH groups A and B Granulocyte colony-stimulating factor (G-CSF): Granulocyte colony-stimulating factor (G-CSF) will be given to all participants by injection under the skin 4 days and 1 day before stem cell collection, and then continued until the stem cell collection is completed. Mozobil: Mozobil will be given to all participants by injection under the skin only if needed per Investigator.

Stem Cell Collection With In-vivo Purging With Bortezomib

Bortezomib will be given subcutaneously (SQ) at 1.3 mg/m2 on day -11 and day -8 followed by Granulocyte colony-stimulating factor (G-CSF) given SQ on day -4 thru day -1 and continued until the collection is completed. Mozobil will be given if needed. There must be at least 72 hours between each dose of bortezomib. NOTE: Multiparametric Flow Cytometry to be performed on samples for BOTH groups A and B Bortezomib: Bortezomib will be given to Group B participants by injection under the skin 11 days and 8 days before stem cell collection. Granulocyte colony-stimulating factor (G-CSF): Granulocyte colony-stimulating factor (G-CSF) will be given to all participants by injection under the skin 4 days and 1 day before stem cell collection, and then continued until the stem cell collection is completed. Mozobil: Mozobil will be given to all participants by injection under the skin only if needed per Investigator.
