Rozrolimupab
Rozrolimupab is a Recombinant antibodies, recombinant antibody mixture, specifically containing 25 Rhesus D, or RhD, human antibodies, and is currently under development by Symphogen for the treatment of immune thrombocytopenic purpura (ITP) and for the prevention of hemolytic disease of the newborn (HDN). Clinical trials Phase two trials have proved to be promising. Utilizing a single intravenous infusion dosing, this phase was held in 41 centers across the United States, Europe, and Asia in order to evaluate an effective dose. The 61 patient study was assessing rozrolimupab's ability to effectively treat ITP and HDN as well as how safe and tolerable the drug is. Common adverse effects included mild to moderate headache, pyrexia, chills, and fatique. The study showed that administration of the drug did effect platelet responses in the blood, with a median time of response of roughly two and a half days, and on average lasting a total of 14 days. Current ITP and HDN treatme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Symphogen
Symphogen is a biotechnology company located in Copenhagen, Denmark that develops protein drugs based on recombinant monoclonal antibody mixtures. These drugs are different from the polyclonal antibody, polyclonal antibodies, as each antibody in the mixture is produced from one carefully selected clone. Their three main areas of therapeutic research are immunoglobulin replacement, cancer, and infectious diseases. The company was founded in 2000 and has patents on a drug discovery platform called Symplex and a drug manufacturing platform called Sympress. By 2009, ten drugs were being developed with rozrolimupab (Sym001) being the lead product.Symphogen. Copenhagen 2008 [cited 2009 15 April 2009]; Available from: http://www.symphogen.com/web/guest. Laboratoires Servier acquired Symphogen in 2020. Partner collaborations Genentech, Inc.: Collaboration pact with Genentech which enables both companies to utilize Symplex technology to help discover new antibodies against three undisclosed ...

Recombinant Antibodies
Recombinant antibodies are antibody fragments produced by using recombinant antibody coding genes. They mostly consist of a heavy and light chain of the variable region of immunoglobulin. Recombinant antibodies have many advantages in both medical and research applications, which make them a popular subject of exploration and new production against specific targets. The most commonly used form is the single chain variable fragment (scFv), which has shown the most promising traits exploitable in human medicine and research. In contrast to monoclonal antibodies produced by hybridoma technology, which may lose the capacity to produce the desired antibody over time or the antibody may undergo unwanted changes, which affect its functionality, recombinant antibodies produced in phage display maintain high standard of specificity and low immunogenicity. Structure and characterization Formats There are several known formats of recombinant antibodies which are commonly produced. ...

Immune Thrombocytopenic Purpura
Immune thrombocytopenic purpura (ITP), also known as idiopathic thrombocytopenic purpura or immune thrombocytopenia, is a type of thrombocytopenic purpura defined as an isolated low platelet count with a normal bone marrow in the absence of other causes of low platelets. It causes a characteristic red or purple bruise-like rash and an increased tendency to bleed. Two distinct clinical syndromes manifest as an acute condition in children and a chronic condition in adults. The acute form often follows an infection and spontaneously resolves within two months. Chronic immune thrombocytopenia persists longer than six months with a specific cause being unknown. ITP is an autoimmune disease with antibodies detectable against several platelet surface structures. ITP is diagnosed by identifying a low platelet count on a complete blood count (a common blood test). However, since the diagnosis depends on the exclusion of other causes of a low platelet count, additional investigations (su ...

Hemolytic Disease Of The Newborn
Hemolytic disease of the newborn, also known as hemolytic disease of the fetus and newborn, HDN, HDFN, or erythroblastosis foetalis, is an alloimmune condition that develops in a fetus at or around birth, when the IgG molecules (one of the five main types of antibodies) produced by the mother pass through the placenta. Among these antibodies are some which attack antigens on the red blood cells in the fetal circulation, breaking down and destroying the cells. The fetus can develop reticulocytosis and anemia. The intensity of this fetal disease ranges from mild to very severe, and fetal death from heart failure (hydrops fetalis) can occur. When the disease is moderate or severe, many erythroblasts (immature red blood cells) are present in the fetal blood, earning these forms of the disease the name ''erythroblastosis fetalis'' (). HDFN represents a breach of immune privilege for the fetus or some other form of impairment of the immune tolerance in pregnancy. Various types of HD ...

Intravenous
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein. The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth. It may also be used to administer medications or other medical therapy such as blood products or electrolytes to correct electrolyte imbalances. Attempts at providing intravenous therapy have been recorded as early as the 1400s, but the practice did not become widespread until the 1900s after the development of techniques for safe, effective use. The intravenous route is the fastest way to deliver medications and fluid replacement throughout the body as they are introduced directly into the circulatory system and thus quickly distributed. For this reason, the intravenous route of administration is also used for the consumpti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrexia
Fever, also referred to as pyrexia, is defined as having a temperature above the normal range due to an increase in the body's temperature set point. There is not a single agreed-upon upper limit for normal temperature with sources using values between in humans. The increase in set point triggers increased muscle contractions and causes a feeling of cold or chills. This results in greater heat production and efforts to conserve heat. When the set point temperature returns to normal, a person feels hot, becomes flushed, and may begin to sweat. Rarely a fever may trigger a febrile seizure, with this being more common in young children. Fevers do not typically go higher than . A fever can be caused by many medical conditions ranging from non-serious to life-threatening. This includes viral, bacterial, and parasitic infections—such as influenza, the common cold, meningitis, urinary tract infections, appendicitis, Lassa, COVID-19, and malaria. Non-infectious causes include ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
