Medical experts launch crowd funding project to investigate effect of malaria drug on colorectal cancer

In continuation of my update on Artesunate


Medical experts investigating whether a common malaria drug could have a significant impact on colorectal cancer have launched a crowd funding project to fund their work.

Scientists at St George's, University of London, and St George's Hospital, are in the second phase of research into whether the malaria drug artesunate, can have a positive effect on colorectal cancer patients by reducing the multiplication of tumour cells and decreasing the risk of cancer spreading or recurring after surgery. If it does the drug could be used to provide a cheap adjunct to current expensive chemotherapy.

Artesunate is derived from the plant Artemisia Annua also known as Sweet Wormwood. The Chinese scientist Tu Youyou whose research in the 1960s led to the development of artesunate from a plant used in Chinese traditional medicine, was recently awarded the Nobel Prize 2015.


Over one million patients are diagnosed with colorectal cancer globally each year. Colorectal cancer is the third most common cancer in men and the second most common cancer in women and is a leading cause of mortality. In the UK,110 new cases are diagnosed daily, with older patients particularly at risk of death (Ferlay et al 2014). Current treatments involve complex combinations of surgery, chemotherapy and radiotherapy.

Unfortunately all these measures have not increased overall survival rates beyond 60% at the 5 year stage after patients receive a diagnosis. New treatments are urgently needed to improve survival rates. Developing new, effective drugs however can take many years and sometimes even decades. Repurposing safe and established existing drugs for cancer treatment is therefore gaining interest amongst the scientific community.

New malaria drug Artesunate, can save millions of lives....


A landmark trial (AQUAMAT trial) showed that the replacement of the standard malaria drug Quinine with the newer drug Artesunate (Artesunate contains artemisinin, which was discovered by a Chinese researcher in 1972 in a project to follow up advice found in ancient Chinese medicine : see structure) for children with severe malaria could save 100,000 lives a year. The World Health Organisation (WHO) recommended that artesunate derived from a Chinese plant called sweet wormwood, replace the four-century-old remedy of quinine for treating severe malaria in adults in 2006. Similar recommendations were not made for children with further trial results pending.
The trial shows that using artesunate reduced death from severe falciparum malaria among African children by 22.5 per cent compared to quinine. The trial spanned over nine African countries, in which 5,425 badly-infected children aged under 15 were given either artesunate or quinine. There were 230 deaths (8.5 percent) in the artesunate group and 297 deaths (11 percent) in the quinine group, the study authors reported. Artesunate was better tolerated than quinine. There was a lower risk of coma or convulsion or serious dropping of blood sugar as occurred with quinine. Hope this trial (a change in treatment policy from quinine to artesunate) will lead to a solution for severe malaria (most common admission diagnosis in febrile children) and can save thousands of children's lives…...
