Racotumomab
Racotumomab (trade name Vaxira) is a therapeutic cancer vaccine for the treatment of solid tumors that is currently under clinical development by ReComBio (R and Research in Computational Biology), an international public-private consortium with the participation of the Center of Molecular Immunology at Havana, Cuba (CIM) and researchers from Buenos Aires University and National University of Quilmes in Argentina. It induces the patient's immune system to generate a response against a cancer-specific molecular target with the purpose of blocking tumor growth, slowing disease progression and ultimately increasing patient survival. Racotumomab triggers an immune response against the tumor antigen N-glycolyl (NGc) GM3 (NGcGM3), a type of ganglioside present on the cell surface of malignant cells from lung and breast, melanoma, as well as neuroectodermal pediatric tumors. Racotumomab has successfully completed a proof-of concept clinical trial in advanced non-small cell lung cancer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-idiotypic
Anti-idiotypic vaccines consist of antibodies that have three-dimensional immunogenic regions, termed idiotopes, that consist of protein sequences that bind to cell receptors. Idiotopes are aggregated into idiotypes specific to their target antigen. An example of an anti-idiotype antibody is Racotumomab. Production and use To produce an anti-idiotypic vaccine, antibodies that bind tumor-associated antigens (TAA) are isolated and injected into mice. To the murine immune system, the TAA antibodies are antigens and cause an immunogenic reaction producing murine antibodies that can bind to the "TAA idiotype" and is said to be "anti-idiotypic". The resulting murine antibodies are harvested and used to vaccinate other mice. The resulting antibodies in the second set of mice have a three-dimensional binding site that mimics the original antibodies that bind tumor-associated antigens. These antibodies are combined with an adjuvant and given as a vaccine. The murine immune system essenti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Health Organization
The World Health Organization (WHO) is a list of specialized agencies of the United Nations, specialized agency of the United Nations which coordinates responses to international public health issues and emergencies.

Lung Cancer
Lung cancer, also known as lung carcinoma, is a malignant tumor that begins in the lung. Lung cancer is caused by genetic damage to the DNA of cells in the airways, often caused by cigarette smoking or inhaling damaging chemicals. Damaged airway cells gain the ability to multiply unchecked, causing the growth of a tumor. Without treatment, tumors spread throughout the lung, damaging lung function. Eventually lung tumors metastasize, spreading to other parts of the body. Early lung cancer often has no symptoms and can only be detected by medical imaging. As the cancer progresses, most people experience nonspecific respiratory problems: coughing, shortness of breath, or chest pain. Other symptoms depend on the location and size of the tumor. Those suspected of having lung cancer typically undergo a series of imaging tests to determine the location and extent of any tumors. Definitive diagnosis of lung cancer requires a biopsy of the suspected tumor be examined by a patholo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Injection Site Reaction
Injection site reactions (ISRs) are reactions that occur at the site of injection of a drug. They may be mild or severe and may or may not require medical intervention. Some reactions may appear immediately after injection, and some may be delayed. Such reactions can occur with subcutaneous, intramuscular, or intravenous administration. Drugs commonly administered subcutaneously include local anesthetics, drugs used in palliative care (e.g., fentanyl and morphine), and biopharmaceuticals (e.g., vaccines, heparin, insulin, growth hormone, hematopoietic growth factors, interferons, and monoclonal antibodies). Signs and symptoms Some reactions, such as pain, may appear immediately. Others may be delayed, such as erythema which may appear 24–96 hours after injection. ISRs commonly seen with subcutaneous injections include: *Bleeding and bruising *Erythema (redness) *Pain *Pruritis (itching) *Swelling *Induration (hardening of the skin) *Discoloration Severe reactions may result i ...

Common Toxicity Criteria
The Common Terminology Criteria for Adverse Events (CTCAE), formerly called the Common Toxicity Criteria (CTC or NCI-CTC), are a set of criteria for the standardized classification of adverse events of drugs and treatment used in cancer therapy. The CTCAE system is a product of the US National Cancer Institute (NCI). The first Iteration was prior to 1998. In 1999, the FDA released version 2.0. CTCAE version 4.0 in 2009 with an update to y version 4.03 in 2010. The current version 5.0 was released on November 27, 2017. Many clinical trials, now extending beyond oncology, encode their observations based on the CTCAE system. It uses a range of grades from 1 to 5. Specific conditions and symptom Signs and symptoms are diagnostic indications of an illness, injury, or condition. Signs are objective and externally observable; symptoms are a person's reported subjective experiences. A sign for example may be a higher or lower temperature ...s may have values or descriptive comment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monoclonal Antibody
A monoclonal antibody (mAb, more rarely called moAb) is an antibody produced from a cell lineage made by cloning a unique white blood cell. All subsequent antibodies derived this way trace back to a unique parent cell. Monoclonal antibodies are identical and can thus have monovalent affinity, binding only to a particular epitope (the part of an antigen that is recognized by the antibody). In contrast, polyclonal antibodies are mixtures of antibodies derived from multiple plasma cell lineages which each bind to their particular target epitope. Artificial antibodies known as bispecific monoclonal antibodies can also be engineered which include two different antigen binding sites ( FABs) on the same antibody. It is possible to produce monoclonal antibodies that specifically bind to almost any suitable substance; they can then serve to detect or purify it. This capability has become an investigative tool in biochemistry, molecular biology, and medicine. Monoclonal antibod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intradermal Injection
Intradermal injection (also intracutaneous or intradermic, abbreviated as ID) is a shallow or superficial injection of a substance into the dermis, which is located between the epidermis and the hypodermis. For certain substances, administration via an ID route can result in a faster systemic uptake compared with subcutaneous injections, leading to a stronger immune response to vaccinations, immunology and novel cancer treatments, and faster drug uptake. Additionally, since administration is closer to the surface of the skin, the body's reaction to substances is more easily visible. However, due to complexity of the procedure compared to subcutaneous injection and intramuscular injection, administration via ID is relatively rare, and is only used for tuberculosis and allergy tests, monkeypox vaccination, and certain therapies. Vaccine dose sparing For vaccination many clinical studies have proven efficacy of ID administration over subcutaneous (SC), intramuscular (IM) or other ...

Alum
An alum () is a type of chemical compound, usually a hydrated double salt, double sulfate salt (chemistry), salt of aluminium with the general chemical formula, formula , such that is a valence (chemistry), monovalent cation such as potassium or ammonium. By itself, "alum" often refers to potassium alum, with the formula . Other alums are named after the monovalent ion, such as sodium alum and ammonium alum. The name "alum" is also used, more generally, for salts with the same formula and structure, except that aluminium is replaced by another Valence (chemistry), trivalent metal ion like chromium#Chromium(III), chromium, or sulfur is replaced by another chalcogen like selenium. The most common of these analogs is chrome alum . In most industries, the name "alum" (or "papermaker's alum") is used to refer to aluminium sulfate, , which is used for most industrial flocculation (the variable is an integer whose size depends on the amount of water absorbed into the alum). For medi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ganglioside
A ganglioside is a molecule composed of a glycosphingolipid (ceramide and oligosaccharide) with one or more sialic acids (e.g. N-acetylneuraminic acid, ''N''-acetylneuraminic acid, NANA) linked on the sugar chain. NeuNAc, an acetylated derivative of the carbohydrate sialic acid, makes the head groups of gangliosides anionic at pH 7, which distinguishes them from globosides. The name ''ganglioside'' was first applied by the German scientist Ernst Klenk in 1942 to lipids newly isolated from ganglion, ganglion cells of the brain. More than 60 gangliosides are known, which differ from each other mainly in the position and number of N-Acetylneuraminic acid, NANA residue (chemistry), residues. It is a component of the cell plasma membrane that modulates cell signal transduction events, and appears to concentrate in lipid rafts. Recently, gangliosides have been found to be highly important molecules in immunology. Natural and semisynthetic gangliosides are considered possible therape ...

Cancer Vaccine
A cancer vaccine, or oncovaccine, is a vaccine that either treats existing cancer or prevents development of cancer. Vaccines that treat existing cancer are known as ''therapeutic'' cancer vaccines or tumor antigen vaccines. Some of the vaccines are "autologous", being prepared from samples taken from the patient, and are specific to that patient. Some researchers claim that cancerous cells routinely arise and are destroyed by the immune system ( immunosurveillance); and that tumors form when the immune system fails to destroy them. Some types of cancer, such as cervical cancer and liver cancer, are caused by viruses ( oncoviruses). Traditional vaccines against those viruses, such as the HPV vaccine and the hepatitis B vaccine, prevent those types of cancer. Other cancers are to some extent caused by bacterial infections (e.g. stomach cancer and ''Helicobacter pylori''). Traditional vaccines against cancer-causing bacteria ( oncobacteria) are not further discussed in this artic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
