Clinical Trial in Chinese Patients of Relapsed and Refractory Peripheral T Cell Lymphoma (GB226)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

Brief Summary:
It is a multi-center, prospective, open-label, two-stage optimized design, single-arm, phase II clinical study to evaluate the efficacy and safety of GB226 for the treatment of relapsed and refractory peripheral T cell lymphoma (PTCL), and to evaluate the immunogenicity of GB226.

Condition or disease Intervention/treatment Phase
Peripheral T Cell 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
