SINGAPORE SCIENTISTS DISCOVER METABOLIC DRUG CAN TREAT TERMINAL WEIGHT LOSS IN CANCER PATIENTS
Finding by researchers from Genome Institute of Singapore, National Cancer Centre Singapore and Duke-NUS Medical School may help cancer patients suffering from terminal weight loss. The Singapore team is now looking at translating the research to benefit cancer patients worldwide
Singapore, 03 May 2016 –
In a world’s first, research investigators in Singapore have discovered a metabolic trick to treat the terminal wasting syndrome, or cachexia, which afflicts millions of patients worldwide who suffer from cancer or other chronic diseases. The team found that muscles were burning fat (fatty acid oxidation) too rapidly during cachexia, resulting in fatal muscle loss. The study was published online on 2 May 2016 in Nature Medicine.
One of the most lethal effects of cancer is cachexia. It affects approximately 80% of advanced cancer patients. Cachexia patients manifest severe involuntary weight loss due to the rapid, irreversible wasting of muscle mass. It severely reduces a patient’s quality of life, diminishes the ability to tolerate cancer treatments like chemotherapy, and increases the risk for secondary illnesses and infections. Cachexia is thought to contribute to approximately 30% of all cancer deaths. However, little is known about how cachexia develops.
Using the latest “Omics” technologies, including genomics and metabolomics, to analyse muscle stem cells afflicted with cachexia, the team identified excessive fatty acid oxidation as the major route by which cachexia develops in patients, thus overturning the long-held assumption that hyper-active fatty acid oxidation is just a by-product of cachexia.
The team has been the first to show that controlling muscle fatty acid oxidation can be used to treat and prevent cancer cachexia. Dr Iain Tan, a medical oncologist at NCCS and a senior author on this study says, “Based on this discovery, we are already planning our first clinical trials into cachexia, which should start this year.” The team had demonstrated the use of a fatty acid oxidation inhibitor drug in treating muscle wasting during cachexia, and is looking towards translating this research to benefit cancer patients worldwide.
This work was spearheaded by Dr Ng Shyh-Chang at A*STAR’s Genome Institute of Singapore (GIS), in close collaboration with Dr Teh Bin Tean and Dr Iain Tan, clinician-scientists at the National Cancer Centre Singapore (NCCS), Duke-NUS Medical School (Duke-NUS) and GIS. Dr Ng Shyh-Chang said, “The strong capabilities built up at GIS and BTI have enabled us to rapidly crack this long-standing, unsolved problem for cancer patients. We are looking forward to treating cancer patients with this drug.”
It was a national effort involving researchers from A*STAR, Duke-NUS, NCCS and cancer surgeons from the National University Hospital and the Singapore General Hospital. Prof Teh Bin Tean, a senior author on the study and Deputy Director (Research) of NCCS emphasised that “This is a great example of how different institutions across the country come together harnessing their expertise and resources to solve an important medical problem. We all look forward to more fruits of such efforts.”
Prof Ng Huck Hui, Executive Director of GIS, said, “Over the past few years, our collaborations with the industry and clinical community have increased greatly in both numbers and impact. These collaborations have proven time and time again that the whole is definitely greater than the sum of its parts – greater outcomes for human health are achieved when we pull our resources and expertise together.”
Prof Soo Khee Chee, Director of NCCS, said, “This finding constitutes a critical step in understanding and treating a major health problem for cancer patients worldwide.”
