Status:	Active, not recruiting
Conditions:	Blood Cancer, Hematology
Therapuetic Areas:	Hematology, Oncology
Healthy:	No
Age Range:	18 - Any

Start Date:	January 2009

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 of the end date of radiotherapy).

- Corticosteroid doses > 10 mg/day of prednisone or equivalent within 2 weeks prior to
first dose of study drug.

- Known positive serology for the human immunodeficiency virus (HIV), hepatitis B
and/or active hepatitis C.

- Additional criteria exist.
