Table 3. Pharmacokinetic parameters of [14C]almonertinib and its metabolites in mixed plasma of participants.
Metabolite No. | T1/2 (h) | tmax (h) | Cmax (ng Eq/g) | AUC0–48 h (h ng Eq/g) | MRT0–48 h (h) | %AUCa (%) |
---|---|---|---|---|---|---|
Total plasma | 105 | 4 | 464 | 15,513 | 22.9 | 100.00 |
[14C]almonertinib | 167 | 4 | 286 | 10,854 | 23.7 | 69.97 |
M440 | 1.95* | 4 | 101 | 788 | 10.7 | 5.08 |
The half-life (T1/2) of M440 was calculated using the data at 4, 6, and 10 h. %AUC = the plasma exposure of the parent drug or metabolite within 0–48 h (AUC0-48 h) (ng×h/mL) ÷ the total plasma exposure within 0–48 h (AUC0-48 h) (ng×h/mL). MRT, mean residence time.
