Prognostic Potential of Cell Surface Markers and Pim Kinases in Multiple Myeloma

April 3, 2018 updated by: Medical University of South Carolina
The purpose of this study is to understand if small proteins found on the surface of myeloma cells (called CXCR4 and CD47) or inside the myeloma cells (Pim kinases, sphingolipids, and pS6) can predict how patients will respond to chemotherapy-treatment and if a small molecule inside the myeloma cells (called Pim kinase) can be used as a treatment target for myeloma. A sample from the bone marrow biopsy (a small amount of tissue removed from the body for laboratory testing) and aspirate (a small amount of fluid is removed from the body for laboratory testing) that had been done before the subject entered this study will be provided for research purposes. Based on preliminary data, it is hypothesized that CXCR4, CD47, sphingolipids, and Pim kinases could be used as prognostic/predictive markers and that Pim kinase inhibitors provide a new agent for the treatment of multiple myeloma.

  • Planned therapy with standard chemotreatment for multiple myeloma
  • Laboratory data such as calcium, beta 2-microglobulin, albumin, creatinine and bone survey available for staging purpose.
  • ≥18 years old

Exclusion Criteria:

  • < 18 years old
  • Patients who will not receive chemotreatment
  • Patients whose treatment records are not available

Cohorts and Interventions

Group / Cohort
Multiple Myeloma subjects with bone marrow aspirate/biopsy
All patients seen at MUSC with a diagnosis of multiple myeloma or possible multiple myeloma who undergo bone marrow aspirate and biopsy will be approached for participation in this study.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Measure the expression levels of CXCR4, CD47, and pS6 by flow cytometry in myeloma patient's marrow aspirate
Time Frame: 3 years
Our Aim 1 is to perform a corrective study to measure the expression levels of CXCR4, CD47, and pS6 by flow cytometry in myeloma patient's marrow aspirate and correlate their expression level with patients' treatment responses
3 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Determine if Pim kinase inhibitors or sphingosine kinase 2 inhibitors will inhibit patients' myeloma cells
Time Frame: 3 years
Our aim 2 involves only in vitro cell culture system and in vivo animal models. We will measure the efficacy of Pim kinase inhibitors in inhibiting patients' myeloma cell growth in vitro using cell culture system. We will also determine the efficacy of Pim kinase inhibitors and sphingosine kinase 2 inhibitors in inhibiting tumor growth of patients' myeloma cells in animal models. We will measure the tumor size in animal models. Our Aim 2 does not involve any measurement of human myeloma patients. Therefore, measures of safety, tolerability etc in patients are not applicable.
