Technetium (99mTc) fanolesomab (trade name NeutroSpec, manufactured by Palatin Technologies) is a mouse monoclonal antibody formerly used to aid in the diagnosis of appendicitis. It is labeled with a radioisotope, technetium-99m (99mTc).
NeutroSpec was approved by the U.S. Food and Drug Administration (FDA) in June 2004 for imaging of patients with symptoms of appendicitis. It consisted of an intact murine (mouse) IgM monoclonal antibody against human CD15, labeled with technetium-99m so as to be visible on a gamma camera image. Since anti-CD15 antibodies bind selectively to white blood cells such as neutrophils, it could be used to localize the site of an infection.
The FDA received reports from Palatin of 2 deaths and 15 life-threatening adverse events in patients who had received NeutroSpec.
These events occurred within minutes of administration of NeutroSpec and included shortness of breath, low blood pressure, and cardiopulmonary arrest. Affected patients required resuscitation with intravenous fluids, blood pressure support, and oxygen. Most, but not all, of the patients who experienced these events had existing cardiac and/or pulmonary conditions that may have placed them at higher risk for these adverse events. A review of all post-marketing reports showed an additional 46 patients who experienced adverse events that were similar but less severe. All of the reactions occurred immediately after NeutroSpec was administered. [1]
Marketing of the product was suspended in December 2005.
Infliximab, a chimeric monoclonal antibody, sold under the brand name Remicade among others, is a medication used to treat a number of autoimmune diseases. This includes Crohn's disease, ulcerative colitis, rheumatoid arthritis, ankylosing spondylitis, psoriasis, psoriatic arthritis, and Behçet's disease. It is given by slow injection into a vein, typically at six- to eight-week intervals.
Natalizumab, sold under the brand name Tysabri among others, is a medication used to treat multiple sclerosis and Crohn's disease. It is a humanized monoclonal antibody against the cell adhesion molecule α4-integrin. It is given by intravenous infusion every 28 days. The drug is believed to work by reducing the ability of inflammatory immune cells to attach to and pass through the cell layers lining the intestines and blood–brain barrier. Natalizumab has proven effective in treating the symptoms of both diseases, preventing relapse, vision loss, cognitive decline and significantly improving quality of life in people with multiple sclerosis, as well as increasing rates of remission and preventing relapse in multiple sclerosis.
Pertuzumab, sold under the brand name Perjeta, is a monoclonal antibody used in combination with trastuzumab and docetaxel for the treatment of metastatic HER2-positive breast cancer; it also used in the same combination as a neoadjuvant in early HER2-positive breast cancer.
Technetium (99mTc) sulesomab is a radio-pharmaceutical composed of anti-human mouse monoclonal antibody that targets the granulocyte associated NCA-90 cell antigen and a conjugated technetium-99m radionuclide. After intravenous administration, Leukoscan enables sensitive and specific whole body measurement of granulocyte infiltration and activation by gamma camera imaging of 99mTc-antibody bound cells. Total clearance of LeukoScan from blood samples after administration and imaging has been reported at 48 hour time points indicating limited retention of the agent in circulation
Technetium-99m (99mTc) is a metastable nuclear isomer of technetium-99, symbolized as 99mTc, that is used in tens of millions of medical diagnostic procedures annually, making it the most commonly used medical radioisotope in the world.
Technetium (99mTc) arcitumomab is a drug used for the diagnostic imaging of colorectal cancers, marketed by Immunomedics. It consists of the Fab' fragment of a monoclonal antibody and a radionuclide, technetium-99m.
Bectumomab is a mouse monoclonal antibody labelled with the radioactive isotope technetium-99m. It is used to detect non-Hodgkin's lymphoma.
Ocrelizumab, sold under the brand name Ocrevus, is a medication used for the treatment of multiple sclerosis (MS). It is a humanized anti-CD20 monoclonal antibody. It targets CD20 marker on B lymphocytes and hence is an immunosuppressive drug. Ocrelizumab binds to an epitope that overlaps with the epitope to which rituximab binds.
Inotuzumab ozogamicin, sold under the brand name Besponsa, is an antibody-drug conjugate medication used to treat relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL).
Ofatumumab is a fully human monoclonal antibody to CD20, which appears to provide rapid B-cell depletion. Under the brand name Kesimpta, it is approved for the treatment of multiple sclerosis in the United States as well as in the European Union and other regions. Under the brand name Arzerra, it is approved for the treatment of certain types of chronic lymphocytic leukemia (CLL) in the United States. It is sold by Novartis under license from Genmab.
Technetium (99mTc) pintumomab (INN) is a mouse monoclonal antibody for the imaging of adenocarcinoma. It is labelled with the radioisotope technetium-99m.
Technetium (99mTc) nofetumomab merpentan is a mouse monoclonal antibody derivative used in the diagnosis of lung cancer, gastrointestinal, breast, ovary, pancreas, kidney, cervix, and bladder carcinoma. The antibody part, nofetumomab, is attached to the chelator merpentan, which links it to the radioisotope technetium-99m (99mTc).
Technetium (99mTc) medronic acid is a pharmaceutical product used in nuclear medicine to localize bone metastases as well as other diseases that can alter the natural turn-over in the bone by bone scintigraphy.
Technetium 99mTc albumin aggregated (99mTc-MAA) is an injectable radiopharmaceutical used in nuclear medicine. It consists of a sterile aqueous suspension of Technetium-99m (99mTc) labeled to human albumin aggregate particles. It is commonly used for lung perfusion scanning. It is also less commonly used to visualise a peritoneovenous shunt and for isotope venography.
Scintimammography is a type of breast imaging test that is used to detect cancer cells in the breasts of some women who have had abnormal mammograms, or for those who have dense breast tissue, post-operative scar tissue or breast implants.
Technetium (99mTc) votumumab is a human monoclonal antibody labelled with the radionuclide technetium-99m. It was developed for the detection of colorectal tumors, but has never been marketed.
Secukinumab, sold under the brand name Cosentyx, is a human IgG1κ monoclonal antibody used for the treatment of psoriasis, ankylosing spondylitis, and psoriatic arthritis. It binds to the protein interleukin (IL)-17A and is marketed by Novartis.
Otilimab is a fully human antibody which has been developed by the biotechnology company MorphoSys. It can also be referred to as HuCAL antibody, HuCAL standing for Human Combinatorial Antibody Library and being a technology used to generate monoclonal antibodies. Otilimab is directed against the granulocyte-macrophage colony stimulating factor (GM-CSF), a monomeric glycoprotein functioning as a cytokine promoting both proliferation and activation of macrophages and neutrophils.
