028300 Company Profile

HLB is a Korean company whose central asset is rivoceranib, a cancer drug it has been pushing toward US approval for liver cancer in combination with a Chinese partner's immunotherapy. The FDA has issued rejections tied to manufacturing and inspection findings, and each resubmission moves the stock sharply. The company also holds a collection of affiliates in diagnostics and other health businesses. It draws unusually heavy attention from American retail investors for a company of its size.
