This study is for patients that have been diagnosed with multiple myeloma. The investigational drugs in this study are lenalidomide and daratumumab. The purpose of this study is to compare overall survival between the two treatment arms with lenalidomide as the comparator arm and lenalidomide + daratumumab/rHuPH20 as the experimental arm in post-autologous transplant multiple myeloma patients. Participants can expect to be on this study for up to 7 years. After 7 years, participants may be followed by telephone for up to 15 years from the time they started study treatment.

This study is for patients that have been diagnosed with smoldering multiple myeloma (SMM). The drugs used in this study are daratumumab, lenalidomide and dexamethasone which are all commercially used drugs. The purpose of this study is to compare overall survival in patients with high-risk smoldering multiple myeloma randomized to daratumumab revlimid-dexamethasone or revlimid-dexamethasone. Participants can expect to be on this study for up to two years and followed by your doctor for up to 15 years.

This study is for patients that have suffered a femur fracture due to metastatic cancer. The standard of care for this type of fracture is to stabilize the bone with an intramedullary nail. When preparing the femur for the nail, pressure can cause fat to enter the bloodstream and travel to the heart, causing heart and lung complications. The procedure being investigated in this study is called reduced pressure reaming. In this procedure the surgeon will use a device with suction when preparing the bone for the nail in order to decrease pressure and decrease the amount of fat that enters the bloodstream. Patients will be randomly assigned to either the standard preparation (standard reaming), or the reduced pressure preparation (reduced pressure reaming). After surgery, both treatment groups will followed according to standard practices at 2 weeks, 6 weeks, 3 months, and 6 months.
