Open to people ages 18 years and up

  • Portion A: Histological or cytological diagnosis of advanced/metastatic solid tumor malignancy or B cell lymphoma, for which no curative therapy is available. Portion A expansion includes patients who have documented disease progression on a checkpoint inhibitor (anti CTLA 4, anti PD1/PD L1 antibodies) per RECIST criteria. Tumor types include metastatic melanoma, renal cell carcinoma (RCC), non-small cell lung cancer(NCSLC) and squamous cell carcinoma of the head and neck (SCCHN). Patients in the dose expansion stage are required to provide archival or baseline (obtained during the screening period) tumor biopsies.
  • Portion B: Histological confirmed relapsed or refractory CD20 positive NHL for which no curative therapy is available. Patients enrolled in the expansion cohort must have archival tissue available, sampled within 6 months of study entry. The Expansion cohort includes patients with FL or DLBCL with relapsed or refractory disease.
  • Measurable disease with at least one extranodal tumor mass >1.0 cm in the greatest transverse diameter (GTD) or in the case of malignant lymph nodes >1.5 cm in the GTD.
  • ECOG performance status of ≤ 1.
  • Adequate bone marrow function, for Portion A: absolute neutrophil count (ANC) ≥ 1.5 x 109/L, platelet count ≥100 x 109/L, hemoglobin >9.0 g/dL. For Portion B: ANC ≥ 1.0 x 109/L, platelet count ≥ 75 x 109/L, and hemoglobin ≥ 8.0 g/dL. In both cases, patients must be transfusion independent at least 14 days prior to screening.
  • Serum creatinine ≤ 2 x ULN or estimated creatinine clearance ≥ 50 ml/min.
  • Total serum bilirubin ≤ 1.5 x ULN unless the patient has documented Gilbert syndrome and AST and ALT ≤ 2.5 x ULN.

  • Prior allogeneic hematopoietic stem cell transplant.
  • Immunosuppressive regimens involving systemic corticosteroids within 14 days before the first dose of study treatment.
  • Therapeutic or experimental monoclonal antibodies within 28 day or prior radiation therapy within 14 days of the first dose of study drug.
  • Autoimmune disorders and other diseases that compromise or impair the immune system.
  • Unstable or serious concurrent medical conditions in the previous 6 months.
  • Prior therapy with any anti CD137 monoclonal antibody.
