Metformin, Nelfinavir, and Bortezomib in Treating Patients With Relapsed and/or Refractory Multiple Myeloma
Study Details
Study Description
Brief Summary
This phase I trial studies the side effects and best dose of metformin and nelfinavir in combination with bortezomib in treating patients with multiple myeloma that has come back or does not respond to treatment. Metformin may stop the growth of tumor cells by disrupting the energy source within multiple myeloma cells. Nelfinavir and bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving metformin, nelfinavir, and bortezomib may work better in treating patients with multiple myeloma.

Detailed Description
PRIMARY OBJECTIVE:
- To assess the maximum tolerated dose (MTD) of administering metformin hydrochloride (metformin) and nelfinavir mesylate (nelfinavir) in combination with bortezomib in patients with relapsed/refractory multiple myeloma.
SECONDARY OBJECTIVES:
-
To describe the safety and tolerability of metformin and nelfinavir in combination with bortezomib in patients with relapsed/refractory multiple myeloma.
-
To assess the best hematological response of the combination of metformin, nelfinavir and bortezomib within 6 cycles of initiating therapy.
EXPLORATORY OBJECTIVE:
- Assess clinical biomarkers predictive of response to the combination of metformin, nelfinavir and bortezomib such as bioenergetic profiles of the myeloma cells, GLUT4 expression on myeloma cells, PI3K/AKT/mTOR and MAPK signaling pathways and metabolomics-based profiling.
OUTLINE: This is a dose-escalation study of metformin hydrochloride and nelfinavir mesylate.
Patients receive metformin hydrochloride orally (PO) on days 1-14, nelfinavir mesylate PO twice daily (BID) on days 1-14, and bortezomib subcutaneously (SC) on days 1, 8, and 15. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

Outcome Measures
Primary Outcome Measures
- Maximum tolerated dose of the combination of metformin, nelfinavir, and bortezomib [42 days]
Defined as the dose level below the lowest dose that induces dose-limiting toxicity (DLT) in at least one-third of patients (at least 2 of a maximum of 6 new patients).
Secondary Outcome Measures
- Incidence of adverse events [Up to 2.5 years]
The maximum grade for each type of adverse event will be recorded for each patient, and frequency tables will be reviewed to determine patterns. Additionally, the relationship of the adverse event(s) to the study treatment will be taken into consideration.
- Hematologic response rate [Up to 2.5 years]
Defined to be a stringent complete response (sCR), complete response (CR), very good partial response (VGPR), or partial response (PR) noted as the objective status on two consecutive evaluations. Exact binomial 95% confidence intervals for the true hematologic response rate will be calculated.
Other Outcome Measures
- Clinical biomarker analysis [Up to 2.5 years]
Will be explored and correlated with response to the combination of metformin, nelfinavir, and bortezomib using Fisher's exact and Wilcoxon rank sum tests. Clinical biomarkers examined may include bioenergetic profiles of the myeloma cells, GLUT4 expression on myeloma cells, PI3K/AKT/mTOR and MAPK signaling pathways and metabolomics-based profiling.
