TQB2916 Injection Combined With Chemotherapy or Penpulimab Injection in the Treatment of Solid Tumors

"TQB2916 is a humanized immune gamma globulins 2 (IgG2) monoclonal antibody targeting CD40.~The mechanism of action of doxorubicin is mainly to destroy the DNA structure of tumor cells, thereby killing malignant tumors. It interferes with the DNA synthesis process of cancer cells by targeting DNA and inhibiting enzymes in DNA replication and repair. In addition, doxorubicin can also trigger cross-link breaks in DNA, leading to apoptosis of cancer cells."

TQB2916 is a humanized IgG2 monoclonal antibody targeting CD40. Penpulimab injection is a programmed cell death protein 1 (PD-1) immune checkpoint inhibitor.
