Cancer immunotherapy (immuno-oncotherapy) is the stimulation of the immune system to treat cancer, improving the immune system's natural ability to fight the disease. It is an application of the fundamental research of cancer immunology (immuno-oncology) and a growing subspecialty of oncology.
Uveal melanoma is a type of eye cancer in the uvea of the eye. It is traditionally classed as originating in the iris, choroid, and ciliary body, but can also be divided into class I and class II. Symptoms include blurred vision, loss of vision, and photopsia, but there may be no symptoms.
Ipilimumab, sold under the brand name Yervoy, is a monoclonal antibody medication that works to activate the immune system by targeting CTLA-4, a protein receptor that downregulates the immune system.
Tremelimumab, sold under the brand name Imjudo, is a fully human monoclonal antibody used for the treatment of hepatocellular carcinoma. Tremelimumab is designed to attach to and block CTLA-4, a protein that controls the activity of T cells, which are part of the immune system.
Medarex was an American biopharmaceutical company based in Princeton, New Jersey, with manufacturing facilities in Bloomsbury and Annandale, New Jersey, and research facilities in Milpitas and Sunnyvale, California. In 2009, Medarex was purchased by Bristol Myers Squibb.
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. BiTE is a registered trademark of Micromet AG.
CancerVax was an American pharmaceutical company founded in 1998 by Donald Morton. The company sought to develop a vaccine for cancer, and had candidates for melanoma reach phase III clinical trials. When those trials proved unsuccessful in 2005, the company soon underwent a reverse takeover with Micromet.
Cixutumumab (IMC-A12) is a human monoclonal antibody for the treatment of solid tumors.
Tigatuzumab (CS-1008) is a monoclonal antibody for the treatment of cancer. As of October 2009, a clinical trial for the treatment of pancreatic cancer, Phase II trials for colorectal cancer, non-small cell lung cancer, and ovarian cancer have been completed.
Glembatumumab vedotin is an antibody-drug conjugate (ADC) that targets cancer cells expressing transmembrane glycoprotein NMB (GPNMB).
Nivolumab, sold under the brand name Opdivo, is an anti-cancer medication used to treat a number of types of cancer. This includes melanoma, lung cancer, malignant pleural mesothelioma, renal cell carcinoma, Hodgkin lymphoma, head and neck cancer, urothelial carcinoma, colon cancer, esophageal squamous cell carcinoma, liver cancer, gastric cancer, and esophageal or gastroesophageal junction cancer. It is administered intravenously.
Talimogene laherparepvec, sold under the brand name Imlygic among others, is a biopharmaceutical medication used to treat melanoma that cannot be operated on; it is injected directly into a subset of lesions which generates a systemic immune response against the recipient's cancer. The final four year analysis from the pivotal phase 3 study upon which TVEC was approved by the FDA showed a 31.5% response rate with a 16.9% complete response (CR) rate. There was also a substantial and statistically significant survival benefit in patients with earlier metastatic disease and in patients who hadn't received prior systemic treatment for melanoma. The earlier stage group had a reduction in the risk of death of approximately 50% with one in four patients appearing to have met, or be close to be reaching, the medical definition of cure. Real world use of talimogene laherparepvec have shown response rates of up to 88.5% with CR rates of up to 61.5%.
Pembrolizumab, sold under the brand name Keytruda, is a humanized antibody, more specifically a PD-1 Inhibitor, used in cancer immunotherapy that treats melanoma, lung cancer, head and neck cancer, Hodgkin lymphoma, stomach cancer, cervical cancer, and certain types of breast cancer. It is administered by slow intravenous injection.
ImmTACs are a class of bispecific biological drug being investigated for the treatment of cancer and viral infections which combines engineered cancer-recognizing TCRs with immune activating complexes. ImmTACs target cancerous or virally infected cells through binding human leukocyte antigen (HLA) presented peptide antigens and redirect the host's cytotoxic T cells to recognise and kill them.
Immutep Ltd is a biotechnology company working primarily in the field of cancer immunotherapy using the LAG3 immune control mechanism. The company was originally built on CVac, a therapeutic cancer vaccine. In late 2014 the privately held French immunotherapy company Immutep SA was purchased by Prima Biotech.
Eftilagimod alpha is a large-molecule cancer drug being developed by the clinical-stage biotechnology company Immutep. Efti is a soluble version of the immune checkpoint molecule LAG-3. It is an APC Activator used to increase an immune response to tumors, and is administered by subcutaneous injection. Efti has three intended clinical settings:
Atezolizumab, sold under the brand name Tecentriq among others, is a monoclonal antibody medication used to treat urothelial carcinoma, non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC), hepatocellular carcinoma and alveolar soft part sarcoma, but discontinued for use in triple-negative breast cancer (TNBC). It is a fully humanized, engineered monoclonal antibody of IgG1 isotype against the protein programmed cell death-ligand 1 (PD-L1).
Ieramilimab is a monoclonal antibody being developed by Novartis for the treatment of cancer. The antibody targets the immune checkpoint LAG-3, which is expressed on T cells and tends to down-regulate an immune response. In a June 2015 presentation Novartis management indicated that 'dosing is imminent' for the first clinical trials of LAG525.
Tebentafusp, sold under the brand name Kimmtrak, is an anti-cancer medication used to treat uveal melanoma. Tebentafusp is a bispecific gp100 peptide-HLA-directed CD3 T cell engager. Tebentafusp is given by intravenous infusion.
Lifileucel, sold under the brand name Amtagvi, is an adoptive T cell therapy used for the treatment of melanoma.
