A trial looking at aspirin and esomeprazole to help prevent cancer of the oesophagus (ASPECT)
This trial was done to find out if aspirin and esomeprazole can help prevent cancer of the food pipe (oesophagus) in people with Barrett's oesophagus. It was supported by Cancer Research UK.
More about this trial
Barrett’s oesophagus is a condition where the cells lining the oesophagus change. It is caused by acid from the stomach coming back up into the oesophagus (acid reflux). People with Barrett’s oesophagus have an increased risk of developing oesophageal cancer. Researchers are keen to find a way to reduce this risk.
Esomeprazole is a type of drug called a proton pump inhibitor or PPI. It reduces the amount of acid produced by the stomach. Doctors hoped that it would help stop Barrett’s oesophagus developing into cancer.
Other clinical trials had already shown that aspirin may help prevent oesophageal cancer. But the research team were not sure how useful it is for people with Barrett’s oesophagus. Aspirin can cause stomach ulcers, but doctors hoped that having esomeprazole with aspirin would stop that happening.
Some people in this trial had high dose esomeprazole and some had low dose esomeprazole. Some also took aspirin.
The aim of this trial was to see if esomeprazole with or without aspirin could help stop Barrett’s oesophagus developing into oesophageal cancer.
