Nimotuzumab (h-R3,[2]BIOMAb EGFR, Biocon, India;[3]TheraCIM, CIMYM Biosciences, Canada; Theraloc, Oncoscience, Europe, CIMAher, Center of Molecular Immunology, Havana, Cuba) is a humanized monoclonal antibody that as of 2014 had orphan status in the US and EU for glioma, and marketing approval in India, China, and other countries for squamous cell carcinomas of the head and neck, and was undergoing several clinical trials.
Like cetuximab, nimotuzumab binds to the epidermal growth factor receptor (EGFR), a signalling protein that normally controls cell division. In some cancers, this receptor is altered to cause uncontrolled cell division, a hallmark of cancer. These monoclonal antibodies block EGFR and stop the uncontrolled cell division.
Nimotuzumab binds with optimal affinity and high specificity to the extracellular region of EGFR (epidermal growth factor receptor). This results in a blockade of ligand binding and receptor activation. Epidermal growth factor receptor (EGFR) is a key target in the development of cancer therapeutics. EGFR-targeting drugs have been shown to improve response when used with conventional treatments such as radiation therapy and chemotherapy.[2]
Development status
It was developed at the Center of molecular immunology (CIM) in Havana, Cuba.[5] CIM's commercialization arm, CIMAB S.A. formed a joint venture with YM Biosciences called CIMYM BioSciences in 1995 that was 80% owned by YM and 20% owned by CIMAB.[6]
CIMYM BioSciences licensed European rights to nimotuzumab to Oncoscience AG in 2003, the South Korean rights to Kuhnil Pharmaceutical Co., Ltd. in 2005, and in 2006, licensed the Japanese rights to Daiichi Sankyo and rights to certain countries in Asia and Africa to Innogene Kalbiotech Pte Ltd.[6] Other licensees for nimotuzumab include Biocon BioPharmaceuticals Ltd. (BBPL) in India, Biotech Pharmaceutical Co. Ltd. in China, Delta Laboratories in Colombia, European Chemicals SAC, Quality Pharma in Peru, Eurofarma Laboratorios Ltda. in Brazil, Ferozsons Labs in Pakistan, Laboratorio Elea S.A.C.I.F.yA. in Argentina, EL KENDI Pharmaceutical in Algeria and Laboratorios PiSA in Mexico.[citation needed]
In December 2012, CIMYM BioSciences dissolved and sold its assets related to nimotuzumab to InnoKeys PTE Ltd.[7]
According to a 2009 review: "Nimotuzumab was approved for the following indications—For squamous cell carcinoma in head and neck (SCCHN) in India, Cuba, Argentina, Colombia, Ivory Coast, Gabon, Ukraine, Peru and Sri Lanka (expired now); for glioma (pediatric and adult) in Cuba, Argentina, Philippines and Ukraine; for nasopharyngeal cancer in China. It has been granted orphan drug status for glioma in USA and for glioma and pancreatic cancer in Europe."[2]
As of 2014 Nimotuzumab was in additional Phase I and II clinical trials.[8]
In April 2014, Daiichi Sankyo announced that it was halting a multicenter, randomized, double-blind, placebo-controlled Phase III study investigating nimotuzumab for first-line therapy in patients with unresectable and locally advanced squamous cell lung cancer, due to safety issues in certain patients who received a combination of cisplatin, vinorelbine, radiotherapy, and nimotuzumab.[9]
Safety
The toxicity and safety of nimotuzumab have been assessed in several pre-clinical and clinical studies wherein it was noticed that side effects usually caused by EGFR inhibitors, especially rashes and other skin toxicities, were negligible. Scientists have hypothesized that this is because nimotuzumab binds only to cells that express moderate to high EGFR levels.[2]
Nimotuzumab has been found to be very well tolerated in clinical trials. Common adverse reactions seen in patients treated with nimotuzumab include:[10][11]
Cetuximab, sold under the brand name Erbitux, is an epidermal growth factor receptor (EGFR) inhibitor medication used for the treatment of metastatic colorectal cancer and head and neck cancer. Cetuximab is a chimeric (mouse/human) monoclonal antibody given by intravenous infusion.
Biocon Limited is an Indian biopharmaceutical company based in Bangalore. It was founded by Kiran Mazumdar-Shaw in 1978. The company manufactures generic active pharmaceutical ingredients (APIs) that are sold in approximately 120 countries, including the United States and Europe. It also manufactures novel biologics as well as biosimilar insulins and antibodies, which are sold in India as branded formulations. Biocon's biosimilar products are also sold in both bulk and formulation forms in several emerging markets.
The epidermal growth factor receptor is a transmembrane protein that is a receptor for members of the epidermal growth factor family of extracellular protein ligands.
Targeted therapy or molecularly targeted therapy is one of the major modalities of medical treatment (pharmacotherapy) for cancer, others being hormonal therapy and cytotoxic chemotherapy. As a form of molecular medicine, targeted therapy blocks the growth of cancer cells by interfering with specific targeted molecules needed for carcinogenesis and tumor growth, rather than by simply interfering with all rapidly dividing cells. Because most agents for targeted therapy are biopharmaceuticals, the term biologic therapy is sometimes synonymous with targeted therapy when used in the context of cancer therapy. However, the modalities can be combined; antibody-drug conjugates combine biologic and cytotoxic mechanisms into one targeted therapy.

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 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. Laboratoires Servier acquired Symphogen in 2020.

Trastuzumab deruxtecan, sold under the brand name Enhertu, is an antibody-drug conjugate consisting of the humanized monoclonal antibody trastuzumab (Herceptin) covalently linked to the topoisomerase I inhibitor deruxtecan.

Trastuzumab binds to and blocks signaling through epidermal growth factor receptor 2 (HER2/neu) on cancers that rely on it for growth. Additionally, once bound to HER2 receptors, the antibody is internalized by the cell, carrying the bound deruxtecan along with it, where it interferes with the cell's ability to make DNA structural changes and replicate its DNA during cell division, leading to DNA damage when the cell attempts to replicate itself, destroying the cell.

It is the first treatment for adults with non-small cell lung cancer whose tumors have specific types of genetic mutations: epidermal growth factor receptor (EGFR) exon 20 insertion mutations.
