Whilst working at Beecham, Wesley Miner and Gareth Sanger discovered that 5-HT3 serotonin receptor antagonists were extremely efficacious pharmacological agents for preventing and treating anti-cancer therapy-induced nausea and vomiting.

Their seminal experimental work translated extremely well to the clinic where Kytril (granisetron) was shown to be highly efficacious in patients.4
