Arms and Interventions

Intervention / Treatment |
---|---|
EXPERIMENTAL: TQB2825 injection
TQB2825 injection is given intravenously every 2 weeks, and every 4 weeks (28 days) as a treatment cycle, with the longest treatment duration not exceeding 2 years.
|
TQB2825 injection is a bi-specific, humanized antibody against CD3×CD20, with the structure ratio of anti-CD3 to anti-CD20 of 1:2.
It has two asymmetric Fab ends and a complete Fc end, and is a natural IgG4 subtype with weak antibody-dependent cell-mediated cytotoxicity or complement dependent cytotoxicityfunction.
By bridging CD3 and CD20, TQB2825 injection induces T cell activation to promote T cell proliferation/expansion, promote the formation of cytolytic synapses, and cause cytotoxic T cells to release perforin and granase, thereby killing CD20 positive tumor cells.
Therefore, TQB2825 injection is intended for the treatment of CD20 positive hematologic tumors, including but not limited to lymphoma, leukemia and myeloma.
