Monoclonal antibodies

Definition

Monoclonal antibodies are laboratory produced antibodies designed to recognise and bind to specific receptors found on the surface of cells. They are derived from natural antibodies, complex proteins derived from a single B cell made by the body's immunological defence system to recognise and fight foreign invaders such as bacteria and viruses.

Importance

It is difficult to overstate the extent to which monoclonal antibodies have transformed healthcare since their introduction in 1975. One of their key advantages is that they are very precise in their target and have a very high degree of sensitivity. This has makes them highly versatile tools for basic research, diagnostics and therapeutics. In 2010 the combined global monoclonal antibody diagnostics and therapeutics market was valued at US$55 billion. In 2012 there were more than 30 monoclonal antibody drugs on the worldwide market. Of these ten were blockbuster drugs, each of them generating more than US$1 billion per year. Today monoclonal antibody drugs account for a third of all new treatments introduced.

Discovery

For many centuries keen observers of epidemic diseases, such as smallpox and plague, noted that individuals who suffered and survived one disease outbreak remained unscathed the next time the same disease passed their way. The knowledge that individuals could acquire immunity to a disease underpinned some of the earliest interventions against smallpox. This involved taking material from the pustules of infected individuals and injecting it into healthy individuals so as to confer immunity. Such measures were taken with very little understanding of how the immune system worked.

In the 1890s Emil von Behring and Kitasato Shibasaburo observed that blood taken from animals infected with diphtheria or tetanus could give immunity to other animals not previously exposed to such diseases. Following this Paul Ehrlich identified that the source of protection in blood came from antibodies and hypothesised that antibodies could be used one day as magic bullets for medicine.

Thereafter, scientists began hunting for a means to isolate and purify individual antibodies from the billions produced by the body's defence system. This was finally achieved in 1975 by Georges Kohler and Cesar Milstein, based at the Laboratory of Molecular Biology in Cambridge, UK, with their development of a technique to produce monoclonal antibodies.

Application

The production of monoclonal antibodies involves several steps. In the first instance a laboratory animal is injected with a desired target to stimulate their immune system. Following this, antibody producing cells, B lymphocytes, are harvested from the animal's spleen and fused with an immortal myeloma cell line to create hybrid cells, or hybridomas. The hybrid cells are then screened to find those that secrete antibodies with the desired specificity for a particular target. Once identified the hybrid cell is cloned to establish a hybridoma colony. This colony is then maintained in a culture medium to provide a continual supply of monoclonal antibodies. Each of the antibodies secreted by the hybrid cell is identical (monoclonal) and has the capacity to bind to a specific receptor found on the surface of a cell.

One of the major advantages of monoclonal antibodies is that they can be produced very cheaply and on a large-scale. They are now routinely used as probes in laboratories to unravel the pathways of numerous diseases, whether it be cancer, Alzheimer’s disease or autoimmune disorders. Monoclonal antibodies are also vital to the typing of tissue for organ transplants and blood for transplants. Everyday they are also used to analyse bodily fluids for diagnosis and to monitor hospital infections. They are also instrumental in the detection of heart attacks. Beyond the clinic, monoclonal antibodies are important components in home-testing kits for determining ovulation, pregnancy, menopause and many other conditions.

In addition to their use in diagnostics, monoclonal antibodies have proven useful as drugs. Since their emergence, monoclonal antibodies have helped improve the treatment of over 50 major diseases. They are used, for example, to prevent the rejection of organ transplants and for the treatment of cancer, inflammatory and autoimmune disorders, cardiovascular disease, infectious diseases, allergies, osteoporosis and ophthalmic problems. They have also been shown to help with migraines and reduce high cholesterol.

Governments are also reliant on monoclonal antibodies for protecting public health. The antibodies are used, for example, in tests to detect and monitor infectious agents like HIV, the cause of AIDS, or the influenza virus causing pandemic flu and for identifying diseases released by biological weapons such as smallpox and anthrax. In addition, monoclonal antibodies help in checks for salmonella and bacteria that cause food poisoning. They are also instrumental in detecting viruses in animal livestock or plants and monitoring environmental pollution.

Monoclonal antibodies: timeline of key events

Antiserum preparted against human oesteogenic sarcoma in an ass and 2 dogs. Reported successful in treating 50 patients suffering from cancer of the stomach and chest wall. J Hericourt, C Richet, 'Traitement d'un cas de sarcome par la sarcome par la serotherapie', Seances Acad Sci, 120 (1895), 948-50.1895-01-01T00:00:00+0000A virologist and physician, Burnet is best known for his discovery of acquired immunological tolerance and demonstrating how the body recognises the difference between self and non-self. Burnet shared the Nobel Prize in Physiology or Medicine in 1960 for this work. His research helped advance the development of vaccines, tissue transplantation, monoclonal antibodies and associated therapies. In addition, Burnett made significant contributions to the development of techniques to grow and study the influenza virus, including hemagglutination assays. Based on his study of the genetics of the virus he showed that the influenza virus recombined at a high frequency. 1899-09-03T00:00:00+0000Jerne shared the 1984 Nobel Prize for Medicine for 'theories concerning the specificity in development and control of the immune system'. He developed three important theories for immunology. Firstly, that antibodies are formed during fetal development and are present in the body from birth. Secondly, that white blood cells, lymphocytes, teach themselves to recognise the body's own substances in the thymus gland. Thirdly, he proposed the network theory which depicts the immune system as a complex self-regulating network that can turn itself on and off when needed. Jerne's work paved the way to development of monoclonal antibodies. He was the founder and director of the Basel Institute of Immunology.1911-12-23T00:00:00+0000A virologist, Koprowski invented the world's first effective live polio vaccine while at Lederle Laboratories. He developed the vaccine by attenuating the virus in brain cells of a cotton rat. In January 1948 he injected the vaccine into himself. The vaccine had the advantage that it directly entered the intestinal tract and provided long-lasting immunity. Within a decade the vaccine had been adopted on four continents. Koprowski went on to become the director of the Wistar Institute where in the 1960s he led efforts to improve the rabies vaccine. He subsequently became the first scientist, together with colleagues, to hold a patent for monoclonal antibodies. Born to Jewish parents, Koprowski was forced to flee Poland in 1939 after Germany invaded the country. 1916-12-05T00:00:00+0000Porter was a biochemist who won the Nobel Prize in Physiology or Medicine in 1972 for helping to determine the chemical structure of antibodies. This was based on some experiments he carried out between 1949 and 1960 while based at St Mary's Medical School in London. He showed that antibodies have a Y-shaped structure, consisting of a large component that has no antigen-combining capacity, at the bottom, and two smaller fragments at the top which have active sites that bind to the antigen. Porter's understanding of the antibody structure and its implications for function opened up the way to the potential use of antibodies as therapeutics and vaccines.1917-10-08T00:00:00+0000Askonas was a leading figure in immunology whose work helped to establish the basic mechanisms and components of immune system. Together with colleagues she developed one of the first systems for the cloning of antibody-forming B cells in vivo, some of the earliest monoclonal antibodies. She was also one of the first scientists to isolate and clone virus specific T lymphocytes, laying the foundation for defining different influenza sub-sets and improving vaccines.1923-04-01T00:00:00+0000Milstein was an Argentinian biochemist. Together with Georges Kohler, Milstein developed the first unlimited supply of long-lasting monoclonal antibodies. Their technique now underpins the development and application of many diagnostics and therapeutics. Kohler and Milstein devised the method as part of their search for a tool to investigate how the immune system can make so many different kinds antibodies, each able to bind to a highly specific receptor on foreign substances that invade the body. 1927-10-08T00:00:00+0000E Witebsky, 'Disponibilitiit und Spezifitat alkoholloslicher Strukturen von Organen und bosartigen Geschwulsten', Zeitschrift fur Imrnunitaetsforschung, Allergie und Klinische Immunologie' 62 (1929), 35-73. 1929-01-01T00:00:00+0000Michael Smith shared the 1993 Nobel Prize for Chemistry for a technique that enables researchers to introduce specific mutations into genes and, thus, to the proteins that they encode. He developed the method, known as site-directed mutagenesis, in the 1970s, in collaboration with Fred Sanger and Clyde A Hutchinson III. The advantage of the technique was that it allowed comparisons to be made of different protein molecules and provided a means to deliberately alter a specific gene thereby making it possible to modify the characteristics of an organism. His work opened up a new chapter for studying and treating genetic diseases. Site-directed mutagenesis is a pivotal tool today in genetic and protein research and engineering and at the forefront of the development of monoclonal antibody drugs. 1932-04-26T00:00:00+0000Klinman was an immunologist who developed the splenic focus assay, a tool that allowed analysis of antibody production derived from single clones of B cells. He used the tool to analyse immune tolerance and immune responses to influenza. In addition he invented the splenic fragment system, a technique that helped generate some of earliest monoclonal antibodies against viral antigens and cancer. 1937-03-23T00:00:00+0000Levy is an oncologist who in 1981 made history by successfully using monoclonal antibodies to treat the first patient with lymphoma. This work laid the foundation for the development of Rituxan, the first monoclonal antibody drug approved by the FDA for the treatment of cancer. Levy is now focused on the development of cancer vaccines. 1941-12-06T00:00:00+0000Feldmann is an immunologist who in the early 1980s developed the hypothesis that cytokines like the tumour necrosis factor (TNF) played an important role in the induction of autoimmune disease like rheumatoid arthritis. Together with Ravinder Maini, he demonstrated that an antibody targeting TNF could block inflammation in the joints of rheumatoid arthritis patients. Feldmann's pioneering work on cytokines also laid the foundation for the successful treatment of other autoimmune disorders like Crohn's disease and anklosing spondylitis. Feldmann left Ukraine with his Jewish parents for France immediately after World War II and then went to Australia at the age of eight. 1944-12-02T00:00:00+0000An oncologist, researcher and venture capitalist, Royston, together with Howard Birndorf and Ted Greene co-founded Hybritech, America's first monoclonal antibody biotechnology company. Hybritech helped kick-start the biotechnology industry in San Diego. Royston also co-founded Idec Pharmaceuticals,the company that developed Rituxan, the first monoclonal antibody drug approved by the FDA for cancer. 1944-11-30T00:00:00+0000Waldmann is an immunologist who demonstrated how monoclonal antibodies could induce tolerance to foreign proteins and transplanted tissues. He and his team developed the first humanised monoclonal antibody (alemtuzumab) which is now used for combating leukaemia, preventing transplant rejection and treating autoimmune disorders such as multiple sclerosis and vasculitis. 1945-02-27T00:00:00+0000Together with Cesar Milstein, Kohler developed the first unlimited supply of long-lasting monoclonal antibodies. Their technique now underpins the development and application of many diagnostics and therapeutics. Kohler and Milstein devised the method as part of their search for a tool to investigate how the immune system can make so many different kinds antibodies, each able to bind to a highly specific receptor on foreign substances that invade the body. 1946-04-17T00:00:00+0000In 1978 Birndorf, along with Ivor Royston, helped found Hybritech, America's first biotechnology company dedicated to monoclonal antibodies. Birndorf went on to found other companies including: Gen-Probe, IDEC Pharmaceuticals (which merged with Biogen to form Biogen-Idec), Ligand, Gensia (Sicor), Neurocrine Biosciences, FastTraQ and Nanogen. 1950-02-21T00:00:00+0000Schoemaker was co-founder and first Chief Executive Officer of Centocor, an American biotechnology company that pioneered the commercialisation of monoclonal antibody diagnostics and therapeutics. After Centocor was sold to Johnson & Johnson for $5.2 billion in 1999, Schoemaker founded Neuronyx to develop cellular therapies. One of the treatments pioneered by Neuronyx was the use of stem cells from bone marrow to help regenerate heart tissue damaged by heart attacks. 1950-03-23T00:00:00+0000A pioneer of protein engineering, Winter invented techniques to both humanise and later to make fully human antibodies for therapeutic uses. Today his technology is used in over two-thirds of antibody drugs on the market, including Humira, a treatment for rheumatoid arthritis and other autoimmune conditions, which in 2012 was listed as the top selling drug in the world. He is also the founder of three biotechnology companies: Cambridge Antibody Technology, Domantis and Bicycle Therapeutics. 1951-03-31T00:00:00+0000A pioneer of antibody engineering, Neuberger developed some of the first techniques for the generation of chimeric and humanised antibodies. He also helped create the first transgenic mice for the production of human monoclonal antibodies. His work paved the way for the generation of safer and more effective monoclonal antibody drugs. 1953-11-02T00:00:00+0000Georges Barski, Serge Sorieul and Francine Cornefert, French scientists at the Institut Gustave Roussy, spot cellular fusion occurs when two different tumour cell lines, taken from two different inbred strains of mice, are grown as a cell mixture in tissue cultures. This observation lays the basis for the development of new techniques for cellular fusion. 1960-01-01T00:00:00+0000Milstein is awarded a three-year MRC contract, arranged by Fred Sanger, to work at the Laboratory of Molecular Biology.1963-01-01T00:00:00+0000The medium was first described by John Littlefield in work he did to characterise four cell lines. He published this in JW Littlefield, 'Selection of hybrids from matings of fibroblasts in vitro and their presumed recombinants,' Science 145 (1964), 709–10.The HAT meidum has the advantage that it can inhibit unfused myeloma cell proliferation. This is particularly important for the growth of monoclonal antibodies. 1964-08-14T00:00:00+0000Norman Klinman, an American immunologist, devises a splenic fragments culture technique for growing antibodies.1969-01-01T00:00:00+0000Brigette Askonas, a Canadian biochemist, Alan Williamson, a British immunologist, and Brian Wright cloned B cells in vivo using spleen cells from mice immunised with haptenated carrier antigen.

Milstein, 'Continuous cultures of fused cells secreting antibody of predefined specificity', Nature 256 (1975), 495-7. Article highlighted that monoclonal antibodies could be invaluable for medical and industrial purposes. By 1993 the paper had been cited in more than 6,905 publications.1975-08-07T00:00:00+0000EA Carswell, LJ Old, RL Kassel, S Green, N Fiore, B Williamson, 'An endotoxin-induced serum factor that causes necrosis of tumors', Proc Natl Acad Sci USA, 72/9 (1975), 3666-70.1975-09-01T00:00:00+0000Koprowski uses myeloma cells from Milstein's laboratory to generate monoclonal antibodies against tumour antigens. This work forms the basis of the first patent later awarded for monoclonal antibodies.1976-09-01T00:00:00+0000The British National Research Development Corporation executives indicate that they will not pursue a patent the technique for producing monoclonal antibodies because they cannot see what diagnostic application it can be used for or any industrial end-products.1976-10-01T00:00:00+0000American geneticist and biochemist, Leonard Herzenberg and Argentinian biochemist, Cesar Milstein, devise monoclonal antibodies for use on an automatic fluorescence-activated cell sorter, FACS.

This would free them up from a dependence on rodents for producing monoclonal antibodies. He publishes the idea in C. Milstein, 'Monoclonal antibodies from hybrid myelomas: Wellcome Foundation Lecture 1980', Proceedings Royal Society of London, 211 (1981), 393-412.1980-01-01T00:00:00+0000Referred to as Campath-1 (CAMbridge Pathology) family of antibodies, these are the first set of monoclonal antibodies against human lymphocytes derived from a rat. 1980-01-01T00:00:00+0000Chaired by Alfred Spinks, the report which examined Britain's state of biotechnology, unfairly singled out Cesar Milstein and his colleagues for the failure. Milstein, however, had approached the National Research Development Corporation to patent the monoclonal antibody technology, but the Corporation failed to take the appropriate action. 1980-02-07T00:00:00+0000Tests begin with 17-1A, also known as edrecolomab, a monoclonal antibody developed at the Wistar Institute. 1980-12-01T00:00:00+0000Argentinian scientists Cesar Milstein and Claudio Cuello demonstrate the feasibility of monoclonal antibodies for use in radioimmunoassay.1981-01-01T00:00:00+0000Philip Karr, a patient with lymphoma, is treated by Ron Levy at Stanford University with a customised monoclonal antibody.

It is a mouse-derived (murine) monoclonal antibody (Muromonab-CD3) that targets a membrane protein on the surface of T cells. OKT3 was first developed in 1979 by Patrick Kung at Ortho Diagnostics as tool to identify different T-cell subsets in humans. It took Kung time to persuade his company to develop the monoclonal antibody as a drug. 1986-06-19T00:00:00+0000Campath-1G is humanised, resulting in Campath-1H.

The technique is published in R Olandi, DH, Gussow, PT Jones and G Winter, 'Cloning immunoglobulin variable domains for expression by polymerase chain reaction', Proc Natl Acad Sci USA, 86 (May 1989), 3833-7. 1988-11-01T00:00:00+0000Gregory Winter together with David Chiswell set up CAT to develop phage display technology for monoclonal antibodies1989-01-01T00:00:00+0000Gregory Winter together with CAT create the first phage monoclonal antibodies, laying the foundation for the generation of diverse libraries of randomly shaped human antibodies. With this scientists are no longer dependent on the natural immune system of animals or humans and the limitations this poses for the production of monoclonal antibodies. 1990-01-01T00:00:00+0000This is achieved by Richard Lerner and Carlos Barbas at the Scripps Research Institute with the backing of Stratagene, an American biotechnology specialising in antibody engineering.1991-01-01T00:00:00+0000European Committee for Proprietary Medicinal Products recommends the approval of Centoxin (Nebacumab) , a drug originally developed by Henry Kaplan and Nelson Tang at Stanford University and prepared for market by Centocor. Based on this recommendation the drug was subsequently approved for market in The Netherlands, Britain, Germany and France between March and December 1991.1991-03-01T00:00:00+0000Developed to treat Gram-negative sepsis, Centoxin originated from research conducted by Henry Kaplan and Nelson Teng based at Stanford University. It was licensed to Centocor, a small biotechnology company in Philadelphia. Following the FDA's request for more information, Centocor watched US$1.5 billion of its market capitalisation disappear. The news also had a devastating impact on other companies developing monoclonal antibody drugs. 1992-02-20T00:00:00+0000Interim trial data from trials show unexpectedly high mortality from Centoxin, leading to withdrawal of the drug from the European market. Reinforces general pessimism about the future for monoclonal antibody drugs. 1993-02-01T00:00:00+0000Three groups of scientists separately report the successful generation of different strains of transgenic mice for the generation of human monoclonal antibodies. Two of the teams are based in biotechnology companies: GenPharm (led by Nils Lonsberg), Cell Gensys (led by Larry Green) , and the other involved a collaboration (led by Marian Bruggemann and Michael Neuberger) between scientists at the Laboratory of Molecular Biology, Braham Institute and the University of Cologne.1994-01-01T00:00:00+0000Jerne shared the 1984 Nobel Prize for Medicine for 'theories concerning the specificity in development and control of the immune system'. He developed three important theories for immunology. Firstly, that antibodies are formed during fetal development and are present in the body from birth. Secondly, that white blood cells, lymphocytes, teach themselves to recognise the body's own substances in the thymus gland. Thirdly, he proposed the network theory which depicts the immune system as a complex self-regulating network that can turn itself on and off when needed. Jerne's work paved the way to development of monoclonal antibodies. He was the founder and director of the Basel Institute of Immunology.1994-10-07T00:00:00+0000Abciximab (ReoPro) approved by the FDA and European regulatory authorities to prevent blot clots during coronary artery procedures like angioplasty. The monoclonal antibody was originally developed by Barry Coller at State University of New York and commercially developed by Centocor. The drug showed for the first time that monoclonal antibodies could be used for the treatment of acute disease conditions. 1994-12-22T00:00:00+0000German regulatory authorities approve Panorex as an adjuvant therapy, that is a drug given in addition to primary or main treatment, for postoperative colorectal cancer. The drug originated from resesearch undertaken by Hilary Koprowski and his colleagues at the Wistar Institute. 1995-01-01T00:00:00+0000German regulatory authorities approve edrecolomab (Panorex) as an adjuvant treatment for post-operative colorectal cancer. The monoclonal antibody, originally known as 17-1A, was developed at the Wistar Institute and commercially developed for market by Centocor. 1995-01-01T00:00:00+0000Together with Cesar Milstein, Kohler developed the first unlimited supply of long-lasting monoclonal antibodies. Their technique now underpins the development and application of many diagnostics and therapeutics. Kohler and Milstein devised the method as part of their search for a tool to investigate how the immune system can make so many different kinds antibodies, each able to bind to a highly specific receptor on foreign substances that invade the body. 1995-03-01T00:00:00+0000Ritxuan (rituiximab) is approved for the treatment of non-Hodgkin Lymphoma. The drug arose out of Ronald Levy's research for three decades to find a way of harnessing the power of the body's own immune system to fight cancer. 1997-01-01T00:00:00+0000Daclizumab was approved by the FDA for the prevention of acute rejection of kidney transplants. The monoclonal antibody was developed by Protein Design Labs using a humanising method devised by Cary Queen and marketed together with F. Hoffmann-La Roche. 1997-12-01T00:00:00+0000The drug is a monoclonal antibody that targets cancer cells that overproduce the HER2/neu oncoprotein1998-01-01T00:00:00+0000The company was set up by Perry Fell and Clay Siegall. The two scientists founded Seattle Genetics after their former employer, Bristol-Myers Squibb cuts its antibody cancer research programme.1998-01-01T00:00:00+00001998-01-01T00:00:00+0000Remicade (infliximab) is approved for the treatment of Crohn's disease. Soon after Remicade wins approval for other autoimmune and inflammatory conditions including rheumatoid arthritis and ulcerative colitis. The drug, a monoclonal antibody against TNF alpha, a powerful promoter of inflammation, was developed in 1989 by Jan Vilcek and Jumning Le and developed in collaboration with Centocor, Marc Feldmann and Maini1998-08-01T00:00:00+0000Genentech agreed to help Seattle Genetics develop SGN-40, one of its drugs for CD40 positive cancers. Under the deal Genentech made an upfront payment of $60 million to Seattle Genetics and agreed to make milestone payments in excess of $800 million and double-digit royalties on any sales.1999-01-01T00:00:00+0000Launched by the biotechnology company Medarex in collaboration with Jim Allison. 2000-01-01T00:00:00+0000Michael Smith shared the 1993 Nobel Prize for Chemistry for a technique that enables researchers to introduce specific mutations into genes and, thus, to the proteins that they encode. He developed the method, known as site-directed mutagenesis, in the 1970s, in collaboration with Fred Sanger and Clyde A Hutchinson III. The advantage of the technique was that it allowed comparisons to be made of different protein molecules and provide a means to deliberately alter a specific gene thereby making it possible to modify the characteristics of an organism. His work opened up a new chapter for studying and treating genetic diseases. Site-directed mutagenesis is a pivotal tool today in genetic and protein research and engineering and at the forefront of the development of monoclonal antibody drugs. 2000-10-04T00:00:00+0000The technology allowed for the development of antibody drug conjugates.2001-01-01T00:00:00+00002001-03-01T00:00:00+0000Milstein was an Argentinian biochemist. Together with Georges Kohler, Milstein developed the first unlimited supply of long-lasting monoclonal antibodies. Their technique now underpins the development and application of many diagnostics and therapeutics. Kohler and Milstein devised the method as part of their search for a tool to investigate how the immune system can make so many different kinds antibodies, each able to bind to a highly specific receptor on foreign substances that invade the body. 2002-03-24T00:00:00+0000The drug, adalimumab (Humira), was approved by the FDA for the treatment of rheumatoid arthritis. It was created using phage display, a technique first invented by Greg Winter in 1990. Cambridge Antibody Technology, BASF Bioresearch Corporation and Abbott Laboratories partnered to develop and market the drug. 2002-12-31T00:00:00+0000The diagnostic, called NeutroSpectT, uses a monoclonal antibody, SSEA1, discovered at the Wistar Institute and developed by Palatin Technologies.2004-04-05T00:00:00+0000Murray was the founder of Sera-Lab, the first biotechnology company to commercialise monoclonal antibodies. His entrepreneurial efforts paved the way to the wide-scale adoption of monoclonal antibodies in research and their clinical application. 2004-10-11T00:00:00+0000The two companies agreed to share the costs and responsibilities of research and product development up to the completion of a Phase 2 clinical study in each party's territory.2005-05-01T00:00:00+0000Schoemaker was a Dutch biochemist who was co-founder and first Chief Executive Officer of Centocor, an American biotechnology company that pioneered the commercialisation of monoclonal antibody diagnostics and therapeutics. After Centocor was sold to Johnson & Johnson for $5.2 billion in 1999, Schoemaker founded Neuronyx to develop cellular therapies. One of the treatments pioneered by Neuronyx was the use of stem cells from bone marrow to help regenerate heart tissue damaged by heart attacks. 2006-01-01T00:00:00+0000Panitumumab (Vectibix) was approved by the FDA for the treatment of patients with EGFR-expressing metatastic colorectal cancer. The drug is a fully human monoclonal antibody created with transgenic mice. It was developed by Agensys with Amgen. 2006-09-27T00:00:00+0000Drug, MSX-1106, to be assessed for malignant melanoma, renal cell cancer, castrate-resistant prostate cancer and non-small cell lung carcinoma2008-11-24T00:00:00+0000Seattle genetics had been developing the drug with Genentech. 2009-01-01T00:00:00+0000The partnership ended because of lack of progress with the drug SGN-40.2009-10-01T00:00:00+0000The partnership allowed for Takeda to obtain overseas approvals for brentuximab vedotin.2009-12-01T00:00:00+0000Klinman was an American immunologist who developed the splenic focus assay, a tool that allowed analysis of antibody production derived from single clones of B cells. He used the tool to analyse immune tolerance and immune responses to influenza. In addition he invented the splenic fragment system, a technique that helped generate some of earliest monoclonal antibodies against viral antigens and cancer.2010-05-04T00:00:00+00002011-02-01T00:00:00+0000The drug was approved for the treatment of unresectable or metastatic melanoma. The drug uses a monoclonal that blocks CTLA-4 so as to activate an immune response against the cancer.2011-03-25T00:00:00+00002011-07-01T00:00:00+00002011-08-01T00:00:00+0000Askonas was a leading figure in immunology whose work helped to establish the basic mechanisms and components of immune system. Together with colleagues she developed one of the first systems for the cloning of antibody-forming B cells in vivo, some of the earliest monoclonal antibodies. She was also one of the first scientists to isolate and clone virus specific T lymphocytes, laying the foundation for defining different influenza sub-sets and improving vaccines. 2013-01-09T00:00:00+0000A Polish-born virologist, Koprowski invented the world's first effective live polio vaccine while at Lederle Laboratories. He developed the vaccine by attenuating the virus in brain cells of a cotton rat. In January 1948 he injected the vaccine into himself. The vaccine had the advantage that it directly entered the intestinal tract and provided long-lasting immunity. Within a decade the vaccine had been adopted on four continents. Koprowski went on to become the director of the Wistar Institute where in the 1960s he led efforts to improve the rabies vaccine. He subsequently became the first scientist, together with colleagues, to hold a patent for monoclonal antibodies. Born to Jewish parents, Koprowski was forced to flee Poland in 1939 after Germany invaded the country. 2013-04-11T00:00:00+0000Alemtuzumab was originally developed by Herman Waldmann as a laboratory tool to investigate immune tolerance. It soon became the first humanised monoclonal antibody drug. Initially alemtuzumab proved effective for helping prevent graft-versus host disease in transplant patients. It subsequently went on to be approved as a treatment for leukaemia and then many years later it was shown to be effective against multiple sclerosis. 2013-09-17T00:00:00+0000A pioneer of antibody engineering, Neuberger developed some of the first techniques for the generation of chimeric and humanised antibodies. He also helped create the first transgenic mice for the production of human monoclonal antibodies. His work paved the way for the generation of safer and more effective monoclonal antibody drugs. 2013-10-26T00:00:00+0000Marketed as Lemtrada, the drug was the first ever ever humanised monoclonal antibody produced. It started life as a laboratory tool for investigating immune tolerance and was subsequently approved for the treatment of leukaemia. The drug has also proven useful for treating a number of other auto-immune conditions including vasculitis. 2014-04-04T00:00:00+0000The drug was developed by scientists at Medarex2014-09-01T00:00:00+0000The drug (nivolumab, Opdivo®), a monoclonal antibody, was approved by the FDA for the treatment of patients with melanoma. The foundation for the drug was laid by the discovery by of the PD-1 protein in 1992 and the work of Gordon Freeman and his team at Dana-Faber Institute which showed that cancer cells can hijack the protein to evade attack by the immune system. 2014-12-22T00:00:00+0000The drugs use a monoclonal antibody to block a protein known as PD-1, which functions as an immune checkpoint, being responsible for preventing the activation of T-cells. Promising results were presented to American Society for Clinical Conference from trials directed towards treating lung and skin cancer. 2015-06-05T00:00:00+0000The drug was developed by Genetech/Roche2016-05-01T00:00:00+0000J.

The trial is being led by Oliver Howe. 2017-11-03T00:00:00+0000The drug was developed by Seattle Genetics with Astellas Pharma. 2018-03-01T00:00:00+00002018-07-01T00:00:00+00002019-06-01T00:00:00+00002019-07-01T00:00:00+0000Developed by Biogen, the drug, aducanumab, targets a protein called amyloid that forms abnormal deposits in the brains of people with Alzheimer's. The company originally discontinued work on the drug in March 2019 after disappointing trial results. 2019-10-22T00:00:00+0000The drug, crizanlizumab, specifically inhibits selectin, a substance that contributes to cells sticking together and causes vaso-occlusive crisis, an extremely painful condition that is frequently a reason for patients to visit emergency departments. 2019-11-15T00:00:00+0000The drug is enfortumab vedotin-ejfv, an antibody drug conjugate. It was given accelerated approval for adult patients with locally advanced or metastatic urothelial cancer who failed to respond to PD1 immune checkpoint therapy or platinum-containing chemotherapy. 2019-12-18T00:00:00+0000The treatment, developed by Regeneron Pharmaceuticals, contains two monoclonal antibodies: casirivimab and imdevimab. The treatment had been trialled in a a randomised, double-blind, placebo-controlled clinical trial in 799 non-hospitalised adults. 2020-11-21T00:00:00+0000The treatment contains tixagevimab with cilgavimab and is intended for individuals with moderate to severely compromised immune systems or severe adverse reactions to a COVID-19 vaccine. 2021-12-08T00:00:00+0000The drug, bebtelovimab, is a neturalising IgG1 monoclonal antibody that binds to the SARS-CoV-2 spike protein. It was developed by AbCellera and Eli Lilly using a high throughput B-cell screening pipeline. . 2022-02-11T00:00:00+0000The results were announced to the Clinical Trials on Alzheimer's Disease in San Francisco by Eisai which is developing the monoclonal antibody, lecanemab) with Biogen. The trial showed lecanemab slowed down the speed at which memory and thinking skills got worse by 27% in people taking the drug compared to those given a placebo. 2022-11-29T00:00:00+0000The drug, lecanemab, was approved under the FDA's Accelerated Approval pathway based on the results from a phase 3 trial. Developed by Eisai and Biogen, the drug targets amyloid beta, a toxic protein that builds up in the brains of Alzheimer's patients. It was evaluated in a double-blind, placebo-controlled, parallel group dose finding study of 856 patients with mild cognitive impairment or mild dementia stage of disease and confirmed presence of amyloid beta. 2023-01-26T00:00:00+00002023-08-30T00:00:00+0000Experiments in rhesus macaques demonstrated that inhaled anti-SARS-CoV-2 antibodies helped decrease virus load in lung tissue, inflammation and disease even when delivered after infection.
