Secondary Outcome Measures:
  • Anti-lymphoma activity as measured by overall response rate [ Time Frame: 24 weeks ]
  • Anti-lymphoma activity as measured by duration of response [ Time Frame: 24 weeks ]
  • Anti-lymphoma activity as measured by progression-free survival [ Time Frame: 24 weeks ]
  • Anti-lymphoma activity as measure by overall survival [ Time Frame: 24 weeks ]
  • Assessment of persistence of ACTR707 as measured by flow cytometry and qPCR [ Time Frame: 24 weeks ]
  • Assessment of ACTR707 phenotype and function as measured by flow cytometry [ Time Frame: 24 weeks ]

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • signed written informed consent obtained prior to study procedures
  • histologically-confirmed relapsed or refractory CD20+ B-cell lymphoma of one of the following types, with documented disease progression or recurrence following the immediate prior therapy: DLBCL (regardless of cell of origin or underlying molecular genetics), MCL, PMBCL, Gr3b-FL, TH-FL (prior dx of FL before transforming to DLBCL).
  • biopsy-confirmed CD20+ expression of the underlying malignancy with disease progression following immediate prior therapy
  • at least 1 measurable lesion on imaging.
  • must have received adequate prior therapy for the underlying CD20+ B-cell lymphoma, defined as an anti-CD20 mAb in combination with an anthracycline-containing chemotherapy regimen (i.e. chemo-immunotherapy) and at least one of the following:

    • biopsy-proven refractory disease after frontline chemo-immunotherapy
    • relapse within 1 year from frontline chemo-immunotherapy and ineligible for autologous hematopoietic stem cell transplant (auto-HSCT)
    • for subjects with DLBCL, PMBCL, and Gr3b-FL: relapsed or refractory disease following at least 2 prior regimens or following an auto-HSCT
    • for subjects with TH-FL: relapsed or refractory disease following at least 2 prior regimens or following an auto-HSCT. At least 1 prior regimen with an anti-CD20 mAb in combination with chemotherapy is required following documented transformation
    • for subjects with MCL (confirmed with cyclin D1 expression or evidence of t(11;14) by cytogenetics, fluorescent in situ hybridization (FISH) or polymerase chain reaction (PCR): relapsed or refractory disease after at least 1 prior regimen with chemo-immunotherapy (prior auto-HSCT is allowable)
  • ECOG 0 or 1
  • life expectancy of at least 6 months
  • platelet count greater than 50,000/µL

Exclusion Criteria:

  • known active central nervous system (CNS) involvement by malignancy.
  • prior treatment as follows:

    • alemtuzumab within 6 months of enrollment
    • fludarabine, cladribine, or clofarabine within 3 months of enrollment
    • external beam radiation within 2 weeks of enrollment
    • mAb (including rituximab) within 2 weeks of enrollment
    • other lymphotoxic chemotherapy (including steroids except as below) within 2 weeks of enrollment
    • experimental agents within 3 half-lives prior to enrollment, unless progression is documented on therapy
  • clinically significant cardiac disease
  • clinically significant active infection
  • clinically significant CNS disorder
  • clinical history, prior diagnosis, or overt evidence of autoimmune disease
  • known bone marrow involvement due to underlying malignant disease, in dose-escalation phase only
