Dendreon
Dendreon is a biotechnology company. Its lead product, Provenge (known generically as sipuleucel-T), is an immunotherapy for prostate cancer. It consists of a mixture of the patient's own blood cells (autologous, with dendritic cells thought to be the most important) that have been incubated with the Dendreon PAP-GM-CSF fusion protein. Phase III clinical trial results demonstrating a survival benefit for prostate cancer patients receiving the drug were presented at the AUA meeting on April 28, 2009. After going through the approval process, Provenge was given full approval by the FDA on April 29, 2010. Dendreon's stock value fell 66% on August 4, 2011, after abandoning its forecast for its debut drug Provenge. In November 2014, Dendreon filed for Chapter 11 bankruptcy protection and shortly afterwards announced that it had reached agreements on the terms of a financial restructuring with certain bond holders. On February 20, 2015, Valeant Pharmaceuticals received approval to pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Immunotherapy
Immunotherapy or biological therapy is the treatment of disease by activating or suppressing the immune system. Immunotherapies designed to elicit or amplify an immune response are classified as ''activation immunotherapies,'' while immunotherapies that reduce or suppress are classified as '' suppression immunotherapies''. Immunotherapy is under preliminary research for its potential to treat various forms of cancer. Cell-based immunotherapies are effective for some cancers. Immune effector cells such as lymphocytes, macrophages, dendritic cells, natural killer cells, and cytotoxic T lymphocytes work together to defend the body against cancer by targeting abnormal antigens expressed on the surface of tumor cells. Vaccine-induced immunity to COVID-19 relies mostly on an immunomodulatory T cell response. Therapies such as granulocyte colony-stimulating factor (G-CSF), interferons, imiquimod and cellular membrane fractions from bacteria are licensed for medical use. Others includin ...

Cancer Vaccines
A cancer vaccine 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 (Cancer immunoediting, 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 (Carcinogenic bacteria, oncobacteria) are not further ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Food And Drug Administration (United States)
The United States Food and Drug Administration (FDA or US FDA) is a federal agency of the Department of Health and Human Services. The FDA is responsible for protecting and promoting public health through the control and supervision of food safety, tobacco products, caffeine products, dietary supplements, prescription and over-the-counter pharmaceutical drugs (medications), vaccines, biopharmaceuticals, blood transfusions, medical devices, electromagnetic radiation emitting devices (ERED), cosmetics, animal foods & feed and veterinary products. The FDA's primary focus is enforcement of the Federal Food, Drug, and Cosmetic Act (FD&C), but the agency also enforces other laws, notably Section 361 of the Public Health Service Act, as well as associated regulations. Much of this regulatory-enforcement work is not directly related to food or drugs, but involves such things as regulating lasers, cellular phones, and condoms, as well as control of disease in contexts varying fro ...

Prostatic Acid Phosphatase
Prostatic acid phosphatase (PAP), also prostatic specific acid phosphatase (PSAP), is an enzyme produced by the prostate. It may be found in increased amounts in men who have prostate cancer or other diseases. The highest levels of acid phosphatase are found in metastasized prostate cancer. Diseases of the bone, such as Paget's disease or hyperparathyroidism, diseases of blood cells, such as sickle-cell disease or multiple myeloma or lysosomal storage diseases, such as Gaucher's disease, will show moderately increased levels. Certain medications can cause temporary increases or decreases in acid phosphatase levels. Manipulation of the prostate gland through massage, biopsy or rectal exam before a test may increase the level. Its physiological function may be associated with the liquefaction process of semen.Page 1135-1136 in: Use in prostatic cancer prognosis Serum marker PSAP was used to monitor and assess progression of prostate cancer until the introduction of prostate sp ...

Private Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''.

Epitope
An epitope, also known as antigenic determinant, is the part of an antigen that is recognized by the immune system, specifically by antibodies, B cells, or T cells. The epitope is the specific piece of the antigen to which an antibody binds. The part of an antibody that binds to the epitope is called a paratope. Although epitopes are usually non-self proteins, sequences derived from the host that can be recognized (as in the case of autoimmune diseases) are also epitopes. The epitopes of protein antigens are divided into two categories, conformational epitopes and linear epitopes, based on their structure and interaction with the paratope. Conformational and linear epitopes interact with the paratope based on the 3-D conformation adopted by the epitope, which is determined by the surface features of the involved epitope residues and the shape or tertiary structure of other segments of the antigen. A conformational epitope is formed by the 3-D conformation adopted by the interac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
