Phase I/II Study of Combination of Aurora Kinase Inhibitor MLN8237 and Bortezomib in Relapsed or Refractory Multiple Myeloma

RATIONALE: Aurora A kinase inhibitor MLN8237 and bortezomib may stop the growth of cancer
cells by blocking some of the enzymes needed for cell growth.

PURPOSE: This phase I/II trial is studying the side effects and best dose of giving aurora A
kinase inhibitor MLN8237 together with bortezomib and to see how well they work in treating
patients with relapsed or refractory multiple myeloma.


I. To determine the maximum tolerated doses (MTD) with the combination of MLN8237 and
bortezomib. (Phase I) II. To describe the toxicities associated with the combination of
MLN8237 and bortezomib. (Phase I) III. To evaluate the overall response rate to the
combination of MLN8237 and bortezomib in patients with relapsed or refractory multiple
myeloma. (Phase II)


I. To assess progression-free and overall survival in patients treated with this
combination. (Phase II) OUTLINE: This is a phase I dose escalation study followed by a phase
II study. Patients receive oral aurora kinase inhibitor MLN8237 once daily on days 1-14 and
bortezomib IV on days 1, 4, 8 and 11. Treatment repeats every 28 days for up to 10 courses
in the absence of disease progression or unacceptable toxicity.

After completion of study treatment all patients are followed every 2 months for 1 year and
then every 3 months for 1 year.

duration of the study

- Male subject agrees to use an acceptable method for contraception for the duration of
the study

- Patients have a baseline LVEF >= 45% at baseline

- Bisphosphonates are considered to be supportive care rather than therapy, and are
thus allowed while on protocol treatment

ULN, the direct bilirubin must be =< 2.0 mg/dL

- Measurable disease of multiple myeloma as defined by at least ONE of the following:

- Serum monoclonal protein >= 1.0 g/dL, >= 200 mg of monoclonal protein in the urine on
24 hour electrophoresis, serum immunoglobulin free light chain >= 10 mg/dL AND
abnormal serum immunoglobulin kappa to lambda free light chain ratio, monoclonal bone
marrow plasmacytosis >= 30% (evaluable disease), or measurable plasmacytoma

non-myelosuppressive agents such as thalidomide or high dose corticosteroids =< 2

exception of complete resection of basal cell carcinoma or squamous cell carcinoma of
the skin, an in situ malignancy, or low-risk prostate cancer after curative therapy
