• At least 1 measurable nodal lesion with longest diameter > 15 mm or 1 measurable extranodal lesion (eg, hepatic nodule) with longest diameter > 10 mm. Additional parameters (e.g., measurable IgM for patients with Lymphoplasmacytic Lymphoma) may be allowed if they meet current NCCN guidelines for symptomatic disease. Patients with uptake by FDG-PET scan may be allowed with prior approval of Sponsor.

• Relapsed or refractory to combination chemotherapy for DLBCL that contains rituximab and an anthracycline; or is intolerable to such agents. Relapsed disease is defined as either recurrence of disease after a CR or PD after achieving a partial response (PR) or SD. Refractory disease is defined as failure to achieve at least SD with any 1 line of therapy or with PD ≤ 3 months of the most recent chemotherapy regimen.
• At least 1 measurable nodal lesion with longest diameter > 15 mm or 1 measurable extranodal lesion (eg, hepatic nodule) with longest diameter > 10 mm. Patients with uptake by FDG-PET scan may be allowed with prior approval of Sponsor.

• Stable (or decreasing) dose of corticosteroids or anti-convulsant medication for at least 7 days prior to dosing
  • [CLOVER-1] Exclusion Criteria:
• Ongoing Grade 2 or greater toxicities due to previous therapies. Stable, tolerable Grade 2 AEs (eg, neuropathy) may be allowed.
• Prior external-beam RT resulting in greater than 20% of total bone marrow receiving greater than 20 Gy.
