A Study of ARRY-520 in Patients With Relapsed or Refractory Multiple Myeloma

United States55 participantsStarted 2009-01

Plain-language summary

This is a 2-phase study during which patients with relapsed or refractory multiple myeloma (MM) or plasma cell leukemia (PCL), who have already received at least two previous treatments, will receive investigational study drug ARRY-520. The study has 3 parts. In the first part of the study, Phase 1, patients will receive increasing doses of study drug, with or without granulocyte-colony stimulating factor (G-CSF) support, in order to achieve the highest dose possible that will not cause unacceptable side effects. Approximately 30 patients from the US will be enrolled in Part 1 (Active, not recruiting). In the second part of the study, Phase 2, patients will receive the best dose of study drug determined from the first part of the study and will be followed to evaluate what side effects the study drug causes and what effectiveness it has, if any, in treating the cancer. Approximately 30 patients from the US will be enrolled in Part 2 (Active, not recruiting). In the third part of the study, Phase 2 with Dexamethasone, patients will receive the best dose of the study drug determined from the first part of the study, in combination with dexamethasone, and will be followed to evaluate what side effects the combination causes and what effectiveness the combination has, if any, in treating the cancer. Approximately 50 patients from the US will be enrolled in Part 3 (Active, not recruiting).

Key Inclusion Criteria (Part 3): * Patients should have received at least two prior treatment regimens. * Confirmed refractory MM (measurable disease) or PCL. Patients must be refractory to treatment with both lenalidomide/dexamethasone and bortezomib/dexamethasone (or to treatment with bortezomib/lenalidomide/dexamethasone), defined as documented progressive disease on therapy or within 60 days of completing treatment with these regimens. * Previously received adequate alkylator therapy. * Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1. * Adequate hematology laboratory values without transfusion support within 2 weeks of screening. * Adequate liver and renal function. * Additional criteria exist. Key Exclusion Criteria (Part 3): * Primary amyloidosis. * Concomitant malignancies or previous malignancies with less than a 3-year disease free interval at the time of enrollment (patients with adequately resected basal or squamous cell carcinoma of the skin, carcinoma in situ of the cervix or Stage A low grade prostate cancer may enroll irrespective of the time of diagnosis). * Autologous or allogeneic stem cell or bone marrow transplant within 3 months prior to first dose of study drug. * Cytotoxic therapy or monoclonal antibodies within 21 days prior to first dose of study drug. * Radiotherapy within 21 days prior to first dose of study drug (if the radiation portal covered ≤ 5% of the bone marrow reserve, the patient may be enrolled irrespective …

What they're measuring

Establish the maximum tolerated dose (MTD) of study drug, with and without G-CSF.
