Eligibility Criteria

Inclusion

  • One of the following progressive advanced or metastatic cancers:
  • Epithelial ovarian, fallopian tube, or primary peritoneal cancer that is platinum refractory or platinum resistant
  • Pancreatic adenocarcinoma that is locally advanced, and now with progressive disease on or after front-line treatment
  • Malignant mesothelioma with epithelioid histology, pleural or peritoneal
  • For Part 2 only - Measurable disease according to RECIST v1.1 for patients with epithelial ovarian, fallopian tube, or primary peritoneal cancer, pancreatic adenocarcinoma, and peritoneal mesothelioma, and mRECIST v1.1 for patients with pleural mesothelioma
  • Available archival tissue sample, or fresh biopsy tissue sample must be obtained prior to enrollment. For Part 2 only- a fresh biopsy tissue sample is required.
  • Adequate bone marrow function, including:
  • Absolute neutrophil count (ANC) ≥1500/mm3 or ≥1.5 x 109/L
  • Platelets ≥100,000/mm3 or ≥100 x 109/L
  • Hemoglobin (Hgb) ≥9 g/dL
  • Adequate renal function, including estimated creatinine clearance ≥30 mL/min
  • Adequate liver function, including:
  • Total serum bilirubin ≤1.5 x upper limit of normal (ULN) unless the patient has documented Gilbert syndrome in which case the maximum total serum bilirubin should be \<5 mg/dL
  • Aspartate and alanine transaminase (AST and ALT) ≤2.5 x ULN or AST/ALT ≤5 x ULN for patients with liver metastases
  • Serum albumin ≥30 mg/mL
  • Key Exclusion Criteria:
  • Brain metastases unless previously treated. Patients with previously treated brain metastases may participate provided they are clinically stable for at least 4 weeks prior to study entry, and have no evidence of new or enlarging brain metastases
  • Evidence of retroperitoneal fibrosis, mesothelial surface (pleura, pericardium, peritoneum) thickening of ≥4 mm; significant or increasing pleural/pericardial effusions, ascites or pericarditis at baseline deemed unrelated to the underlying malignancy based on computed tomography (CT), magnetic resonance imaging (MRI), or echocardiogram (ECHO); or prior history of pleurodesis, retroperitoneal fibrosis or mediastinal fibrosis.
  • Previous Grade 3/4 infusion or hypersensitivity reaction (not immunotoxicity) to treatment with another monoclonal antibody.
  • For patients with tumor types other than pleural mesothelioma: Ascites requiring \>1 paracentesis for therapeutic purposes (i.e., not for diagnosis) within 1 month prior to Cycle 1 Day 1.
