Tivantinib (ARQ197; by Arqule, Inc.) is an experimental small molecule anti-cancer drug. It is a bisindolylmaleimide that binds to the dephosphorylated MET kinase in vitro . (MET is a growth factor receptor.) Tivantinib is being tested clinically as a highly selective MET inhibitor. [1] However, the mechanism of action of tivantinib is still unclear.[ citation needed ]

Tivantinib displays cytotoxic activity via molecular mechanisms that are independent from its ability to bind MET, notably tubulin binding, which likely underlies tivantinib cytotoxicity. [2]

Possible applications include non-small-cell lung carcinoma, hepatocellular carcinoma, and oesophageal cancer. [3]

In 2017, it was announced that a phase III clinical trial for advanced hepatocellular carcinoma had failed to meet the primary endpoint. [4] [5]

c-Met, also called tyrosine-protein kinase Met or hepatocyte growth factor receptor (HGFR), is a protein that in humans is encoded by the MET gene. The protein possesses tyrosine kinase activity. The primary single chain precursor protein is post-translationally cleaved to produce the alpha and beta subunits, which are disulfide linked to form the mature receptor.

<span class="mw-page-title-main">Targeted therapy</span> Type of therapy

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.

Bavituximab (PGN401) is a human-mouse chimeric monoclonal antibody against phosphatidylserine, which is a component of cell membranes that is exposed when a cell is transformed into solid tumor cancer cell or dies, and when cells are infected with hepatitis C. The process of cell death is highly controlled and so there usually no immune response to phosphatidylserine but when bavituximab binds to it, the conjugate appears to stimulate an immune response in humans.

Apatinib, also known as rivoceranib, is a tyrosine kinase inhibitor that selectively inhibits the vascular endothelial growth factor receptor-2. It is an orally bioavailable, small molecule agent which is thought to inhibit angiogenesis in cancer cells; specifically, apatinib inhibits VEGF-mediated endothelial cell migration and proliferation thus blocking new blood vessel formation in tumor tissue. This agent also mildly inhibits c-Kit and c-SRC tyrosine kinases.

Zoptarelin doxorubicin consists of doxorubicin linked to a small peptide agonist to the luteinizing hormone-releasing hormone (LHRH) receptor. It has been developed as a potential treatment for a number of human cancers. The LHRH receptor is aberrantly present on the cell surface of approximately 80% of endometrial and ovarian cancers, 86% of prostate cancers and about 50% of breast cancers. Whereas in normal tissues, expression of this receptor is mainly confined to the pituitary gland, reproductive organs and hematopoietic stem cells. To a lesser extent the LHRH receptor is also found on the surface of bladder, colorectal, and pancreatic cancers, sarcomas, lymphomas, melanomas, and renal cell carcinomas.

Tumor-associated macrophages (TAMs) are a class of immune cells present in high numbers in the microenvironment of solid tumors. They are heavily involved in cancer-related inflammation. Macrophages are known to originate from bone marrow-derived blood monocytes or yolk sac progenitors, but the exact origin of TAMs in human tumors remains to be elucidated. The composition of monocyte-derived macrophages and tissue-resident macrophages in the tumor microenvironment depends on the tumor type, stage, size, and location, thus it has been proposed that TAM identity and heterogeneity is the outcome of interactions between tumor-derived, tissue-specific, and developmental signals.
