Brief Summary:
An open-label, single-arm, phase II clinical study of anti-PD-1 antibody GB226 in treatment of recurrent or refractory B-cell non-Hodgkin's lymphoma (B-NHL)

Condition or disease Intervention/treatment Phase
B-cell Non-Hodgkin's Lymphoma Biological: GB226 Phase 2

Detailed Description:
GB226, 3mg/kg/time, is intravenously infused once every two weeks until disease progression, intolerable toxicity or study withdrawal decided by the investigator/subject. It is expected that each subject will be followed for 2 years. Subjects receiving GB226 treatment will be followed once every 2 weeks to the end of this study. If the patients terminate the treatment and their imaging assessment shows no progressive disease (PD), they should be followed once every 6 weeks until progressive disease (imaging evaluation). If the patients have progressive disease (imaging assessment), they should be followed every 3 months until the end of this study or premature withdrawal from the study. Relevant tests and evaluation should be completed at each visit according to standard of care. The follow-up visits can be performed by telephone. During the study, subjects must complete one imaging test and efficacy evaluation every 6 weeks until disease progression. Moreover, patients should be closely monitored for adverse events from subject enrollment to 30 days after the last dosing

Criteria

Inclusion Criteria:

  • Age ≥18 years old, male or female;
  • Understanding of procedures and contents of the study, and voluntary signing of written informed consent form;
  • Histopathologically confirmed Primary Mediastinal B-cell Lymphoma (PMBCL):

    1. Recurrence after autologous hematopoietic stem cell transplantation (ASCT), or failure to achieve complete response (CR) or partial response (PR) within 60 days after ASCT. If patients with recurrent or refractory PMBCL after ASCT receive other interventions, the disease shall be recurrent or refractory after the last systemic treatment; or:
    2. Patients not suitable for ASCT must be those with the disease that does not respond to or reoccurs after second-line systemic chemotherapy or above. Local radiotherapy is not considered a separate first-line treatment;
    3. History of treatment with rituximab or incapability of receiving rituximab for any reason;
  • Consent to provide archived tumor tissue samples or fresh tissue samples;
  • ECOG score: 0-1;
  • Expected survival ≥ 3 months;
  • Computed tomography scans performed within 28 days prior to study enrollment should show at least one tumor lesion that can be clearly measured in two perpendicular directions. The longest diameter of intranodal lesion is >1.5 cm, and the longest diameter of extranodal lesion is >1.0 cm (according to the 2014 lugano standard);
  • At least 2 weeks after completion of systemic chemotherapy and targeted therapy; at least 4 weeks after systemic or local palliative radiotherapy;
  • At least 2 weeks after discontinuance of systemic corticosteroids (prednisone >10 mg/day or equivalent dose) before enrollment;
  • At least 4 weeks after completion of autologous hematopoietic stem cell transplantation before enrollment or contraindication for autologous hematopoietic stem cell transplantation;
  • At least 4 weeks after completion of major surgery requiring general anesthesia and recovery from the surgery before enrollment; at least 2 weeks after completion of surgery requiring local anesthesia/epidural anesthesia and recovery from the surgery before enrollment; at least 1 hour after completion of skin biopsy requiring local anesthesia only;
