Study of the mass balance, biotransformation, and safety of [ ¹⁴C]IBI351 in healthy Chinese subjects.

ABSTRACT: IBI351, a synthetic compound, exerts its anti-tumor effects by specifically, covalently, and irreversibly modifying the 12th cysteine residue of KRAS G12C. However, the pharmacokinetic profile of IBI351 in humans has not yet been reported. The current study aimed to investigate the pharmacokinetics and safety of IBI351 in healthy Chinese male subjects. A single oral dose of 600 mg combined with 150 μCi [ ¹⁴C]IBI351 was administered to six healthy male volunteers. Blood, urine, and fecal samples were collected at multiple time points to quantify the parent drug and its metabolites. IBI351 showed favorable pharmacokinetic characteristics and was well tolerated by all participants. Seventeen major metabolites were identified in plasma, urine, and feces.
