Olmutinib (INN)[1] is an investigational anti-cancer drug. It acts by covalently bonding to a cysteine residue near the kinase domain of epidermal growth factor receptor (EGFR).[2]

In the US, it was given a breakthrough therapy designation in non-small cell lung cancer (NSCLC) in December 2015, and In South Korea, the drug was approved in May 2016 for the second-line treatment of NSCLC with the T790M mutation of EGFR.[2] Resistance to olmutinib has been reported; a person's cancer started progressing after they developed a C797S mutation in EGFR.[2][3]

Olmutinib was discovered by Hanmi Pharmaceutical and licensed to Boehringer Ingelheim in 2015 in an agreement with a $50 million up front payment and up $680 million in milestones.[4] In November 2015 Hanmi granted an exclusive license to sell olmutinib in China to the Chinese company ZAI Labs.[5]

On September 30, 2016, Korean regulatory authorities issued a safety alert about olmutinib in which it described two cases of toxic epidermal necrolysis, one of which was fatal, and a case of Stevens–Johnson syndrome; Boeheringer announced the termination its deal with Hanmi the same day, citing that the decision came after a review of "all available clinical data" on the drug, and also referring to competing drugs.[6]
