Anti-PD-1 Antibody Alone or in Combination With Low-dose Decitabine and/or Chemotherapy in Relapsed or Refractory Malignancies: an Open-label Phase I/II Trial
The purpose of this study is to assess the feasibility, safety, and efficacy of anti-PD-1 antibody alone or in combination with low-dose decitabine in patients with relapsed or refractory malignancies, including Non-Hodgkin'lymphoma, Hodgkin'lymphoma, gastrointestinal cancers, hepatocellular carcinoma, breast cancer, ovarian cancer or lung cancer or renal-cell cancer or pancreatic cancer or bile duct cancer.
• Subjects must have histological confirmation of relapsed or refractory malignancies,including Non-Hodgkin'lymphoma, Hodgkin'lymphoma, gastrointestinal cancers, hepatocellular carcinoma, breast cancer, ovarian cancer or lung cancer or renal-cell cancer or pancreatic cancer or bile duct cancer.
• 12 to 75 years of age.
• ECOG performance of less than 2.
• Life expectancy of at least 3 months.
• Subjects with lymphoma must have at least one measureable lesion \>1 cm as defined by lymphoma response criteria; with solid tumors must have at least one measureable lesion \>1 cm per RECIST1.1.
• Subjects must have received at least two prior chemotherapy regimen, and must be off therapy for at least 4 weeks prior to Day 1. Subjects with autologous hematopoietic stem-cell transplantation are eligible which must be more than 3 months.
• Subjects must have adequate bone marrow, live, renal, lung and heart functions.
