It will continue with the ongoing clinical trial through completion as Eli Lilly plans to carry out additional clinical studies based on existing preclinical and clinical data.“It is very meaningful that Lilly — one of the most closely watched innovators globally — has recognized the development potential for sonefpeglutide” said Lim Ju-hyun, vice chair at Hanmi Pharmaceutical. “Guided by our mission of ‘Respect for People and Value Creation,’ we will continue to advance innovative drug development.”Hanmi Pharmaceutical stock, listed on Korea’s main bourse Kospi, jumped on the back of the outlicensing deal, trading at 523,000 won ($345) per share as of 2 p.m., up 6.52 percent from the previous day’s closing price.
