Apricoxib is an experimental anticancer drug and nonsteroidal anti-inflammatory drug (NSAID).^[1] It is a COX-2 inhibitor which is intended to improve standard therapy response in molecularly defined models of pancreatic cancer.^[2] It was also studied in clinical trials for non-small-cell lung cancer.^[3] Development was abandoned in 2015 due to poor clinical trial results.^[4]
