A Phase I Trial Evaluating Escalating Doses of 211At-Labeled Anti-CD38 Monoclonal Antibody (211At-OKT10-B10) Combined With Melphalan as Conditioning Prior to Autologous Hematopoietic Cell Transplantation for Patients With Multiple Myeloma

Description:

This phase I trial studies the side effects and best dose of 211At-OKT10-B10 when given together with melphalan before a stem cell transplantation in treating patients with multiple myeloma. The radioimmunotherapy drug 211At-OKT10-B10 is a monoclonal antibody, called OKT10-B10, linked to a radioactive substance called 211At. OKT10-B10 attaches to CD38 positive cancer cells in a targeted way and delivers 211At to kill them. Drugs used in chemotherapy, such as melphalan, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving 211At-OKT10-B10 with melphalan before a stem cell transplant may kill more cancer cells.
