A Brief About The Study Behind this Recent Outbreak ~
Described by researchers as a “largely incurable disease”, acute myeloid leukemia (AML) is a cancer that causes the bone marrow to produce a large number of abnormal blood cells. A study has discovered that blocking an enzyme in the body’s cells which senses changes in oxygen levels could stop the disease from progressing. In the presence of oxygen, these enzymes – known as hypoxia-inducible factor prolyl hydroxylases (PHDs) – become active to target and destroy proteins called hypoxia-inducible factor (HIF). When oxygen levels are low, PHD enzymes are less active, leading to higher HIF levels. The study, co-led by the Institute of Cancer Research, London, and the University of Oxford, explored if boosting HIF levels could prevent the progression of AML. They genetically modified mice and de-activated PHD enzymes, which increased HIF levels and stopped disease progression without impacting the production of normal blood cells. A similar enzyme-blocking process is used in drugs that treat anaemia, according to researchers, and showed the same effect on leukaemia in mouse cells and patient samples. The research team has also created a new compound called IOX5, which inhibits PHDs without impacting other enzymes. Kamil Kranc, a professor of haemato-oncology at The Institute of Cancer Research, London, said: “Therapy for acute myeloid leukaemia has barely changed in several decades."

Added Important Remarks ~ 

• “There is a huge need to discover better treatments for this aggressive disease. “We’ve shown for the first time that targeting the pathways that cells use to respond to oxygen levels could provide a new way to treat leukaemia, without impacting the normal production of blood cells within the bone marrow.” AML is most common in patients over the age of 75. According to the NHS, there are about 3,100 people diagnosed with the disease each year in the UK.
• Prof Kranc added: “Our next challenge is to progress the existing drugs and our new, more selective compound, to clinical trials.“We’re hopeful this research will pave the way towards a new era of AML treatments, and we’d like to explore whether these therapies could also be beneficial for solid tumors.” Professor Kristian Helin, chief executive of The Institute of Cancer Research, London, said: “Cancer exists in a complex ecosystem within the body. “This work provides important insights into that ecosystem and how cancer uses signals within the environment – such as those relating to oxygen levels – to grow and develop. “This study is also an excellent example of cancer researchers and chemists working closely together to develop and test new cancer therapeutics. “It’s exciting to see how a concept develops through a fundamental discovery project and the development of a first-in-class small molecule inhibitor, to potentially benefit patients with this devastating type of cancer, and I look forward to seeing this research progress into clinical trials.”

Concluding Remark: 

Helen Knight, director of medicines evaluation at, the National Institute for Health and Care Excellence (NICE), said: “We are committed to getting the best care to patients fast while ensuring good value for the taxpayer. “Advanced B-cell lymphoma is an aggressive form of blood cancer and can progress quickly. The sooner people can access the best treatment for them, the better chance they have of living for longer and improving their quality of life.“This is why it is such good news that our independent committee has found that glofitamab is clinically proved and cost-effective for treating people with this advanced form of cancer, and we welcome the news that NHS England will make this available to patients quickly.”
