This is an open-label, single dose, mass balance and biotransformation study conducted at 1 study center in China. This study will evaluate the absorption, distribution, metabolism, and elimination (ADME), mass balance, safety, and tolerability of a single dose of intravenously administered \[14C\]Iruplinalkib (WX-0593) in Chinese healthy male volunteers.
