[5] In March 2015 Hanmi and Lilly signed an exclusive license outside of Asia for Hanmi's small molecule Bruton's tyrosine kinase inhibitor in the field of autoimmune diseases; Lilly paid $50 million upfront and the deal included up to $640 million in milestones and royalties greater than 10%.

[4] In July Hanmi said it intended to invest more heavily in developing candidate substances of promising new drugs at an early stage in new pharmaceutical and biotech related fields, including through a venture capital firm set up by Sung-ki and colleagues.

In May 2016 the Korean regulatory authority approved olmutinib as a second-line treatment for certain kinds of non-small cell lung cancer.

Hanmi's offices were raided by Korean regulatory authorities in mid-October based on evidence that insider knowledge of the Boehringer termination was passed to third parties, who shorted the stock prior to the announcement on the 30th.

[17][18] 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.

[19] In April 2018 Hanmi was found to have violated two laws in Korea by not disclosing adverse effects of olmutinib sooner.
