BiTE® technology: designed to ENGAGE T CELLS TO FIGHT CANCER
The need for new therapeutic approaches remains high
Despite recent advances in immuno-oncology, not enough patients benefit from current treatments and additional options are needed to address both hematologic malignancies and solid tumors.
- Certain immuno-oncology therapies and chemotherapies do not target tumor-associated antigens1,2
- Not enough patients experience long-term benefits and with the potential cost of high toxicity2,3
BiTE® technology is designed to engage the natural power of T cells
Cytotoxic T cells play an important role in the body's immune defense by identifying and eliminating cancer cells; however, cancer cells can develop mechanisms to evade T-cell recognition and destruction.4-6
Bispecific T-cell Engager (BiTE®) technology is designed to overcome cancer cells’ evasion of the immune system by engaging patients’ own T cells to directly target cancer cells. BiTE® molecules are engineered from two flexibly linked, single-chain antibodies, with one designed to specifically target a selected tumor-associated antigen and the other targeting CD3 found on T cells.4,7,8
This versatile technology is engineered with the goal of delivering off-the-shelf therapies that direct patients’ own T cells to target a tumor-associated antigen, activating their cytotoxic potential.4,7 Currently being investigated in multiple solid and hematological malignancies, BiTE® technology aims to close the space between tumors and treatment.4

BiTE® technology is designed to fight cancer cells
The BiTE® molecule is designed to recruit a T cell to bind to a cancer cell, leading to the formation of a cytolytic synapse4,10
The T cell becomes activated, releasing perforin and granzymes; fusion of perforin with the cancer cell membrane allows granzymes to enter the cancer cell to induce apoptosis9,10
Following cancer cell apoptosis, activated T cells release cytokines and produce additional perforin and granzymes that may allow T cells to target surrounding cancer cells; this potentially results in the serial lysis of multiple cancer cells by a single T cell4,10,11
Sustained activation of a single activated cytotoxic T cell theoretically results in local proliferation and expansion of polyclonal memory T cells4,10,12
BiTE® technology has the potential to be ready when patients need it
- Engineered with the goal of delivering off-the-shelf therapies to enable patients, including those with aggressive tumors, to initiate treatment immediately4,7
- Does not depend on ex vivo manipulation of patients' cells4,7
- Investigated for use as monotherapies and in combination with other treatments8,9
