The purpose of this study is to characterize the pharmacokinetics (PK) and safety profile of asciminib following a single oral dose in adult subjects with renal impairment compared to a matched group of healthy subjects with normal renal function. The results will determine whether or not a dose adjustment should be recommended when treating patients with asciminib who have impaired renal function.

Pharmacokinetics: Plasma concentration of asciminib by AUClast
The AUC from time zero to the last measurable concentration sampling time (tlast) (ng\*h/mL)
Time frame: pre-dose (0 hour) and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 36, 48 and 72 hours post-dose
Pharmacokinetics: Plasma concentration of asciminib by AUCinf
The AUC from time zero to infinity (ng\*h/mL)
Time frame: pre-dose (0 hour) and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 36, 48 and 72 hours post-dose
Pharmacokinetics: Plasma concentration of asciminib by Cmax
The maximum (peak) observed plasma, blood, serum, or other body fluid drug concentration after single dose administration (ng/mL)
Time frame: pre-dose (0 hour) and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 36, 48 and 72 hours post-dose
Pharmacokinetics: Clearance of asciminib from plasma by CL/F
The total body clearance of drug from the plasma (L/h)
Time frame: pre-dose (0 hour) and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 36, 48 and 72 hours post-dose
Asciminib PK parameters unbound AUClast (AUClast)u and unbound AUCinf (AUCinf)u based on unbound fraction in plasma
including but not limited to: (AUClast)u: area under the unbound plasma concentration-time curve calculated to the last quantifiable concentration point (ng\*h/mL)), \- (AUCinf)u: unbound plasma concentration-time curve extrapolated to infinity. It is calculated as AUCinf ,u= AUClast ,u+ Clast,u/Lambda\_z. (ng\*h/mL)
Time frame: pre-dose (0 hour) and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 36, 48 and 72 hours post-dose
