Inclusion Criteria:

• Adult patients (> 18 years old) with Mantle Cell Lymphoma that has been confirmed by central pathology review (archival diagnostic tumor specimen required)

Patients are considered refractory to Velcade® if they have documented radiological progression on or within 12 months of last dose of Velcade® when given alone or, on or within 12 months from the last dose of the last component of a combination therapy which included Velcade®).

Patients are considered refractory to Velcade®, if Velcade® is part of a combination treatment for the disease.

• Patients must have received at least one prior antineoplastic agent, other than Velcade® either separately or in combination with bortezomib (Velcade®).
• At least one site of measurable nodal disease at baseline >2.0 cm in the longest transverse diameter and clearly measurable in at least two perpendicular dimensions, as determined by CT scan (or MRI, only if CT scan can not be performed)
• ECOG performance status = 0, 1 or 2
• Life expectancy ≥ 3 months
• Adequate bone marrow, liver and renal function
• Platelets ≥ 75 x 109/L (untransfused platelets)
