Enoticumab (REGN421, INN) is a human monoclonal antibody that binds to DLL4. It acts as an immunomodulator. [1] [2] [3] [4] [5]
Mucin-16(MUC-16) also known as Ovarian cancer-related tumor marker CA125 is a protein that in humans is encoded by the MUC16 gene. MUC-16 is a member of the mucin family glycoproteins. MUC-16 has found application as a tumor marker or biomarker that may be elevated in the blood of some patients with specific types of cancers, most notably ovarian cancer, or other conditions that are benign.
Cancer immunotherapy is the stimulation of the immune system to treat cancer, improving on the immune system's natural ability to fight the disease. It is an application of the fundamental research of cancer immunology and a growing subspecialty of oncology.
Radioimmunotherapy (RIT) uses an antibody labeled with a radionuclide to deliver cytotoxic radiation to a target cell. It is a form of unsealed source radiotherapy. In cancer therapy, an antibody with specificity for a tumor-associated antigen is used to deliver a lethal dose of radiation to the tumor cells. The ability for the antibody to specifically bind to a tumor-associated antigen increases the dose delivered to the tumor cells while decreasing the dose to normal tissues. By its nature, RIT requires a tumor cell to express an antigen that is unique to the neoplasm or is not accessible in normal cells.
A TNF inhibitor is a pharmaceutical drug that suppresses the physiologic response to tumor necrosis factor (TNF), which is part of the inflammatory response. TNF is involved in autoimmune and immune-mediated disorders such as rheumatoid arthritis, ankylosing spondylitis, inflammatory bowel disease, psoriasis, hidradenitis suppurativa and refractory asthma, so TNF inhibitors may be used in their treatment. The important side effects of TNF inhibitors include lymphomas, infections, congestive heart failure, demyelinating disease, a lupus-like syndrome, induction of auto-antibodies, injection site reactions, and systemic side effects.
Abagovomab is a mouse anti-idiotype monoclonal antibody whose variable epitope mirrors a tumour antigen (CA-125) highly expressed in the epithelial ovarian cancer. Abagovomab does not bind directly to CA-125, but it works as a "surrogate" antigen, enabling the immune system to identify and attack tumour cells displaying the CA-125 protein. Through this, it is hoped that the body's immune system may be able to combat any remaining individual tumour cells and thus prevent recurrence of the disease.
Tremelimumab, sold under the brand name Imjudo, is a fully human monoclonal antibody against CTLA-4. It is an immune checkpoint blocker.
Mesothelin, also known as MSLN, is a protein that in humans is encoded by the MSLN gene.
Etaracizumab, also known as MEDI-522, trade name Abegrin, is a humanized monoclonal antibody which is being investigated for the treatment of metastatic melanoma, prostate cancer, ovarian cancer and various other types of cancer. It is manufactured by MedImmune.
CD47 also known as integrin associated protein (IAP) is a transmembrane protein that in humans is encoded by the CD47 gene. CD47 belongs to the immunoglobulin superfamily and partners with membrane integrins and also binds the ligands thrombospondin-1 (TSP-1) and signal-regulatory protein alpha (SIRPα). CD-47 acts as a don't eat me signal to macrophages of the immune system which has made it a potential therapeutic target in some cancers, and more recently, for the treatment of pulmonary fibrosis.
Glypican-3 is a protein that, in humans, is encoded by the GPC3 gene. The GPC3 gene is located on human X chromosome (Xq26) where the most common gene encodes a 70-kDa core protein with 580 amino acids. Three variants have been detected that encode alternatively spliced forms termed Isoforms 1 (NP_001158089), Isoform 3 (NP_001158090) and Isoform 4 (NP_001158091).
Programmed cell death protein 1, also known as PD-1 and CD279, is a protein on the surface of T and B cells that has a role in regulating the immune system's response to the cells of the human body by down-regulating the immune system and promoting self-tolerance by suppressing T cell inflammatory activity. This prevents autoimmune diseases, but it can also prevent the immune system from killing cancer cells.
Tumor-associated glycoprotein 72 (TAG-72) is a glycoprotein found on the surface of many cancer cells, including ovary, breast, colon, lung, and pancreatic cancers. It is a mucin-like molecule with a molar mass of over 1000 kDa.
Siltuximab is a chimeric monoclonal antibody. It binds to interleukin-6. Siltuximab has been investigated for the treatment of neoplastic diseases: metastatic renal cell cancer, prostate cancer, other types of cancer, and for Castleman's disease.
Immune checkpoints are regulators of the immune system. These pathways are crucial for self-tolerance, which prevents the immune system from attacking cells indiscriminately. However, some cancers can protect themselves from attack by stimulating immune checkpoint targets.
Axelopran is a drug which is under development by Theravance Biopharma and licensed to Glycyx for all indications. It acts as a peripherally acting μ-opioid receptor antagonist and also acts on κ-, and δ-opioid receptors, with similar affinity for the μ- and κ-opioid receptors and about an order of magnitude lower affinity for the δ-opioid receptor. Recent data suggests that μ-opioid antagonists have a direct effect on overall survival in patients with advanced cancer.
PD-1 inhibitors and PD-L1 inhibitors are a group of checkpoint inhibitor anticancer drugs that block the activity of PD-1 and PDL1 immune checkpoint proteins present on the surface of cells. Immune checkpoint inhibitors are emerging as a front-line treatment for several types of cancer.
V-domain Ig suppressor of T cell activation (VISTA) is a type I transmembrane protein that functions as an immune checkpoint and is encoded by the C10orf54 gene.
Dostarlimab, sold under the brand name Jemperli, is a monoclonal antibody used as a medication for the treatment of endometrial cancer. Dostarlimab is a programmed death receptor-1 (PD-1)–blocking monoclonal antibody.
Globo H (globohexaosylceramide) is a globo-series glycosphingolipid antigen that is present on the outer membrane of some cancer cells. Globo H is not expressed in normal tissue cells, but is expressed in a number of types of cancers, including cancers of the breast, prostate, and pancreas. Globo H’s exclusivity for cancer cells makes it a target of interest for cancer therapies.
Oligoclonal antibodies are an emerging immunological treatment relying on the combinatory use of several monoclonal antibodies (mAb) in one single drug. The composition can be made of mAb targetting different epitopes of a same protein (homo-combination) or mAb targeting different proteins (hetero-combination). It mimicks the natural polyclonal humoral immunological response to get better efficiency of the treatment. This strategy is most efficient in infections and in cancer treatment as it allow to overcome acquired resistance by pathogens and the plasticity of cancers.
