Bi-specific T-cell engager (BiTE) is a class of artificial bispecific monoclonal antibodies that are investigated for use as anti-cancer drugs. They direct a host's immune system, more specifically the T cells ' cytotoxic activity, against cancer cells.
Schematic structure of an antibody–drug conjugate (ADC) Antibody–drug conjugates or ADCs are a class of biopharmaceutical drugs designed as a targeted therapy for treating cancer. [1] Unlike chemotherapy, ADCs are intended to target and kill tumor cells while sparing healthy cells. As of 2019, some 56 pharmaceutical companies were ...
In the cancer disease state, the interaction of PD-L1 on the tumor cells with PD-1 on a T-cell reduces T-cell function signals to prevent the immune system from attacking the tumor cells. [9] Use of an inhibitor that blocks the interaction of PD-L1 with the PD-1 receptor can prevent the cancer from evading the immune system in this way. [ 9 ]
Thus they serve as immunomodulators in immunotherapy (therapy that makes use of immune responses), which can be helpful in treating cancer (where targeted therapy often relies on the immune system being used to attack cancer cells) and in treating autoimmune diseases (in which the immune system attacks the self), such as some kinds of arthritis ...
The cells are expanded non-specifically and/or stimulated. The cells are then reinfused and produce an immune response against the tumour cells. [34] The technique has been tested on refractory stage IV metastatic melanomas [33] and advanced skin cancer. [35] [36] [37] The first FDA-approved CAR-T drug, Kymriah, used this approach. To obtain ...
Biologics can be composed of sugars, proteins, nucleic acids, or complex combinations of these substances, or may be living cells or tissues. They (or their precursors or components) are isolated from living sources—human, animal, plant, fungal, or microbial. They can be used in both human and animal medicine. [2] [3]
One possible treatment for cancer involves monoclonal antibodies that bind only to cancer-cell-specific antigens and induce an immune response against the target cancer cell. Such mAbs can be modified for delivery of a toxin , radioisotope , cytokine or other active conjugate or to design bispecific antibodies that can bind with their Fab ...
Micrograph showing a PD-L1 positive non-small cell lung carcinoma. PD-L1 immunostain. As of 2019, pembrolizumab is used via intravenous infusion to treat inoperable or metastatic melanoma, metastatic non-small cell lung cancer (NSCLC) in certain situations, as a first-line treatment for metastatic bladder cancer in patients who cannot receive cisplatin-based chemotherapy and have high levels ...
