One of the following progressive advanced or metastatic cancers:\n\n 1. Epithelial ovarian, fallopian tube, or primary peritoneal cancer that is platinum refractory or platinum resistant\n 2. Pancreatic adenocarcinoma that is locally advanced, and now with progressive disease on or after front-line treatment\n 3. Malignant mesothelioma with epithelioid histology, pleural or peritoneal\n2. 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\n3. 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.\n4. Adequate bone marrow function, including:\n\n 1. Absolute neutrophil count (ANC) ≥1500/mm3 or ≥1.5 x 109/L\n 2. Platelets ≥100,000/mm3 or ≥100 x 109/L\n 3. Hemoglobin (Hgb) ≥9 g/dL\n5. Adequate renal function, including estimated creatinine clearance ≥30 mL/min\n6. Adequate liver function, including:\n\n 1. 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\n 2. Aspartate and alanine transaminase (AST and ALT) ≤2.5 x ULN or AST/ALT ≤5 x ULN for patients with liver metastases\n7. Serum albumin ≥30 mg/mL\n\nKey Exclusion Criteria:\n\n1. 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\n2. 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.\n3. Previous Grade 3/4 infusion or hypersensitivity reaction (not immunotoxicity) to treatment with another monoclonal antibody.\n4.
