Brief summary

This randomized phase II trial studies glutamine in preventing peripheral neuropathy in patients with multiple myeloma who are receiving bortezomib. Glutamine may help prevent peripheral neuropathy in patients receiving chemotherapy

Detailed description

PRIMARY OBJECTIVES: I. Estimate the objective effect size of glutamine compared to placebo as a prophylactic intervention to prevent bortezomib-induced peripheral neuropathy in multiple myeloma patients 4 months after their first dose of study drug. SECONDARY OBJECTIVES: I. Estimate whether glutamine delays or prevents the onset or worsening of any neuropathy as determined by National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events (CTCAE) v4.03 criteria. II. Determine if glutamine may improve adherence to bortezomib therapy. III. Assess response rate (RR) and clinical benefit response rate (CBR) according to uniform international response criteria and modified European Group for Blood and Marrow Transplantation (EBMT) criteria. IV. Determine if glutamine may improve quality of life (QOL) at 4 months. OUTLINE: Patients are randomized to 1 of 2 treatment arms. ARM I: Patients receive glutamine orally (PO) twice daily (BID). Courses repeat every 28 days for 4 months in the absence of disease progression or unacceptable toxicity. ARM II: Patients receive placebo PO BID. Courses repeat every 28 days for 4 months in the absence of disease progression or unacceptable toxicity.

Design outcomes

Primary

MeasureTime frameDescription
Degree of Peripheral Neuropathy (PNP)up to 4 months from start of studyThe Neuropathy Impairment Score -Lower Limbs (NIS-LL) is the objective measurement of PNP symptoms. The degree of PNP will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) v4.03. The CTCAE is a 0-5 scale that assesses severity of neuropathy related to cancer therapy with higher scores meaning more symptoms A difference of 2 points between groups is considered significant. This measure will be performed at baseline and at 4 months.

Secondary

MeasureTime frameDescription
Adherence to Bortezomib TreatmentUp to 4 monthsAdherence reported as a percentage based on number of doses of study drug taken divided by the expected number of doses of study drug expected to be taken for the study duration.
RR (Complete Remission [sCR+CR+Very Good Partial Remission [VGPR]+Partial Remission [PR])up to 4 months from start of studyRR (sCR+CR+VGPR+PR) according to uniform international response criteria and CBR (RR+MR according to modified EBMT criteria) will be assessed with SPEP, 24h UPEP, serum urine immunofixation, and serum free light chain assay at the start of each cycle and after completion of the 4th cycle.
Average Change in Quality of Life Scores From Baseline to End of Studyfrom baseline to end of study at 4 monthsQuality of life will be measured on the 27-item Functional Assessment of Cancer Therapy-General (FACT-G) including 26 summed items (responses 0 to 4 to equal a possible total score 0-108). Higher scores represent better quality of life. Average change in Quality of Life scores from baseline to end of study will be reported for each separate arm
