Tigatuzumab (CS-1008) is a monoclonal antibody [1] for the treatment of cancer. As of October 2009, a clinical trial for the treatment of pancreatic cancer, [2] Phase II trials for colorectal cancer, [3] non-small cell lung cancer, [4] and ovarian cancer [5] have been completed.

The drug targets member 10b of the tumor necrosis factor receptor superfamily (TNFRSF10B, better known as death receptor 5 or trail receptor 2), a protein with limited expression in normal tissues but overexpressed in many kinds of tumours, including colon, gastric, pancreatic, lung, and cervical. [6] [7]

In 2015, a Phase I study was completed to investigate how biodistribution, quantitative tumor uptake, and antitumor response in patients with metastatic colorectal cancer was impacted by CS-1008. These objectives were tracked through use of trace-labeling and SPECT imaging over the course of treatment and found heterogeneity of tigatuzumab uptake in tumors, that tigatuzumab uptake is not dose dependent, and that tigatuzumab uptake is predictive of clinical response in the treatment of metastatic colorectal cancer.

Targeted therapy drug treatment which interacts with or blocks synthesis of specific cellular components, to impede the biochemical dysfunction involved in progression of the disease

Targeted therapy or molecularly targeted therapy is one of the major modalities of medical treatment (pharmacotherapy) for cancer, others being hormonal therapy and cytotoxic chemotherapy. As a form of molecular medicine, targeted therapy blocks the growth of cancer cells by interfering with specific targeted molecules needed for carcinogenesis and tumor growth, rather than by simply interfering with all rapidly dividing cells. Because most agents for targeted therapy are biopharmaceuticals, the term biologic therapy is sometimes synonymous with targeted therapy when used in the context of cancer therapy. However, the modalities can be combined; antibody-drug conjugates combine biologic and cytotoxic mechanisms into one targeted therapy.
