Can monoclonal antibodies treat Covid-19?įor the past 30 years, monoclonal antibodies have transformed the way we treat various diseases – they proved to be more effective, better tolerated and easier to deliver than other treatments. Two experimental antibody therapies against Ebola are being used to great effect as part of an emergency access programme in the Democratic Republic of the Congo.Īnd several antibodies that can act against different strains of HIV are also in development. Monoclonal antibodies could have a huge impact on the way we treat and prevent infectious diseases. Out of more than 100 licensed monoclonal antibodies, only seven are for treating and preventing infectious diseases – though many more are in development, including candidates for SARS-CoV-2, the virus that causes Covid-19. Monoclonal antibodies have transformed the way we treat multiple cancers, including breast cancer, for which the drug Herceptin has been a game changer. In the past few decades, cancer immunotherapies have saved the lives of millions of people around the world. The majority of the monoclonal antibodies on the market are for noncommunicable diseases, such as autoimmune diseases, like rheumatoid arthritis and cancer. When it comes to COVID-19 vaccines how can governments back a winner?.How to measure the success of a COVID-19 vaccine?.How clinical vaccine trials are speeding up in a pandemic.Manufacturers are looking into ways to reduce production costs, for example through novel technologies and using alternatives to hamster cells (such as algae, yeast and plants) that would change the way these drugs are made. The costs are even higher for start-up companies. Some estimate that the cost of producing one gram of marketed monoclonal antibodies is between $95 and $200 this doesn’t include the costs of research and development, or packaging, delivering and administering the medicine. This whole process takes a long time and uses costly materials. The resulting antibodies are then purified and packaged so they can be easily administered. Most monoclonal antibodies are produced in Chinese hamster ovary cells which are typically grown in large bioreactors for around 10 to 15 days. Then they replicate and manufacture them in large quantities. Making monoclonal antibodies is complex and expensive.įirst, scientists extract the relevant antibodies from human blood. Monoclonal antibodies work by binding to their specific targets – for example viruses, bacteria or cancerous cells – and making them harmless. Antibodies can be designed to attach to different molecules in the body, for example, to turn down the immune response when it overreacts this phenomenon, which also happens with some Covid-19 patients, is called a ‘cytokine storm’.ĭue to their numerous applications, monoclonal antibodies have been safely and effectively used to treat a growing number of diseases, some of which were difficult to treat in the past. This target is not always a ‘foreign intruder’, like a virus. They bind to their specific target, without harming anything else in their way. Monoclonal antibodies work in the same way too. ![]() They block the action of the target, or they flag it as foreign so that other parts of our immune system can clear the ‘invaders’ away. They work by binding to their specific targets – for example viruses, bacteria or cancerous cells – and making them harmless. How do they work?Īntibodies are proteins produced by our immune system and are one of the main ways the body defends itself against diseases. This is one of the fastest-growing fields in biomedical research, and an increasingly important segment of the pharmaceutical market – last year, seven of the top 10 best-selling drugs were monoclonal antibodies. Around 50 of these were brought to market in the past six years alone. Since then, millions of people have benefitted from more than 100 such treatments. The first monoclonal antibody product was licensed more than 30 years ago. This is why they’re sometimes called ‘designer antibodies’ – they are tailor-made to the disease they treat. They are based on natural antibodies – which are proteins that the body produces to defend itself against disease – but are created in the lab and mass-produced in factories. They are not chemical compounds, as most drugs are. Monoclonal antibodies are a class of medicines that have transformed the way we prevent and treat diseases, from cancer and diseases of the immune system, to childhood viral infections.
