Pharmacokinetics and pharmacodynamics of plerixafor in patients with non-Hodgkin lymphoma and multiple myeloma.
Abstract
Phase I pharmacokinetic (PK) and pharmacodynamic (PD) studies in healthy volunteers demonstrated that plerixafor (AMD3100), a CXCR4 antagonist, administered either alone or with granulocyte colony-stimulating factor (G-CSF), resulted in dose-dependent mobilization of CD34(+) cells in the peripheral blood. The purpose of this study was to evaluate the safety and the PK and PD of plerixafor with G-CSF in patients with non-Hodgkin lymphoma (NHL) and multiple myeloma (MM). This was a phase II, open-label, single-arm study conducted in 2 centers in Canada. Patients aged 18 to 70 years with NHL or MM eligible for autologous transplantation were eligible. A total of 22 patients (8 with NHL and 14 with MM) were enrolled in the study. The patients were given G-CSF (10 microg/kg/day subcutaneously [s.c.]) for 4 days in the morning and plerixafor 240 microg/kg s.c. on the evening before each day of apheresis. Apheresis was initiated 10 to 11 hours after each evening dose of plerixafor and after the morning dose of G-CSF. This regimen was repeated for up to 5 days or until > or = 5 x 10(6) CD34(+) cells/kg were collected. The objectives were to determine the safety and efficacy of plerixafor in patients with NHL and MM, and the PK and PD o...Continue Reading

Blood And Marrow Transplantation
The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
B-Cell Lymphoma
B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.
Allogenic & Autologous Therapies
Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
