5. Lung cancer, trachea and bronchus: Lung disease, particularly lung cancer, is number 5 of the top 10 killers. It is responsible for over 1.6 million deaths worldwide. Lung cancer is a particularly aggressive and serious form of cancer that is very common in smokers, accounting for 85% of cases. Countries such as Spain and Hungary are highly affected by the disease, and in China, it is the most common type of cancer. Leading the research into lung cancer are prominent pharmaceutical companies such as AstraZeneca, Merck and Roche. In early 2017, AstraZeneca had their drug Tagrisso approved after demonstrating that it reduces many lung cancer symptoms including appetite loss, fatigue, breathlessness and chest pain. In October 2016, the FDA approved KEYTRUDA, an immunotherapy treatment developed by Merck. Immunotherapy, which involves stimulating the body’s natural immune capabilities to fight cancer, is currently a focus for many pharmaceutical companies as it has proved quite effective in treating various types of the disease. However, a lot of research is still needed to find out the full capabilities of this kind of treatment. 4. Chronic obstructive pulmonary disease (COPD): The fourth leading cause of death globally is a cluster of airway conditions that fall under the term chronic obstructive pulmonary disease. These include chronic bronchitis and emphysema, which are conditions that make the lungs inflamed and damaged. The main cause is smoking, although COPD can affect non-smokers, particularly asthma patients and those who live in very polluted areas. Asian populations are most affected because of high levels of pollution in countries such as Nepal, North Korea and India. COPD is estimated to be the cause of 3.17 million deaths every year. Front-runners in research include AstraZeneca and GlaxoSmithKline (GSK). AstraZeneca has several early and late stage COPD drugs in their pipeline, including benralizumab which has been effective so far in improving lung function. GSK also has several COPD drugs in various stages, including many in phase II and III such as mepolizumab, which has been seen as a breakthrough for patients suffering with severe asthma. top-10-causes-of-death. 3. Lower respiratory infections COPD.: Lower respiratory infections are the deadliest communicable diseases in the world, which are triggered by viruses and bacteria. These diseases affect the patient’s lungs and airways. Examples include influenza (the flu), bronchitis and pneumonia. Global flu epidemics and pneumonia are known to cause devastation in elderly and infant populations every year. In 2015, pneumonia killed 920,136 children under the age of 5, mostly in South Asia and sub-Saharan Africa. The introduction of vaccines has been incredibly effective in lowering mortality rates over the past 20-30 years, particularly in developing countries. Polypher, a Swiss pharmaceutical company, is currently trialling the drug Murepavadin, which has proved successful in treating 9 out of 10 patients with antibiotic resistant pneumonia. As the flu virus is constantly changing, the flu vaccine composition is adapted each year to make it as effective as possible. 2. Stroke :The second leading cause of death worldwide is stroke. A stroke occurs when the blood supply to the brain is disrupted, causing brain cells to die. This can lead to brain injury, disability and in some cases, death. The main causes of a stroke are from a blockage/blood clot (ischaemic) or a ruptured blood vessel (haemorrhagic). Most prevalent in developing countries in South East Asia and the Caribbean, strokes account for 6.24 million deaths per year. There has been a recent breakthrough in clinical research with PCSK9 inhibitors, which are injectable drugs that dramatically lower cholesterol levels when combined with a statin. This has been seen to lower the risk of stroke and heart attacks in patients. The first PCSK9 drugs to be approved were Sanofi and Regeneron’s alirocumab and Amgen’s evolocumab in the summer of 2015. In early 2017 it was announced that a promising treatment for strokes is being made more widely available to patients: the mechanical thrombectomy. This is a device that can remove a stroke-causing clot with the help of clot-busting drugs, and has shown to significantly improve quality of life in the months following the stroke. 1. Ischaemic heart disease (coronary artery disease): heart disease.Topping the list of the world’s most deadly diseases is Ischaemic heart disease, more commonly known as coronary artery disease. Responsible for nearly 9 million deaths every year, heart disease is caused by a build-up of fatty deposits on the wall of the arteries, usually attributed to lifestyle choices or other conditions such as high blood pressure or diabetes. This disease is deadly as the patient’s arteries become narrowed, restricting blood and oxygen flow to the heart, potentially leading to a fatal heart attack. Non-deadly attacks cause chest pain known as angina, which can proceed a heart attack. Eastern European countries such as Ukraine, Uzbekistan and Kyrgyzstan suffer the highest number of casualties, most likely due to the heavy drinking culture and high levels of pollution. As the number one cause of death, it’s a major point of focus for several pharmaceutical companies, many of which are currently developing better treatments to help patients with heart disease. A global leader in cardiovascular disease is Pfizer, which has drug PF-06282999 in early clinical phase development and is continuously seeking ways to treat the causes behind cardiovascular disease. Similarly, AstraZeneca boasts a strong cardiovascular pipeline with promising drugs across all clinical phases.
