Primary | To characterize the pharmacokinetic profile of a single 400-mg dose of pacritinib and its major metabolites in patients with hepatic impairment as compared to gender-, age-, and body mass index -matched healthy subjects with normal liver function | Plasma concentrations of pacritinib and any major metabolites were determined by a validated, sensitive, and specific high performance liquid chromatography/tandem mass spectrometric assay. The lower limit of quantitation of the assay is 20 ng/mL for pacritinib and 4 ng/mL for PAC-M1 metabolite in plasma | Plasma: 0, 1, 2, 4, 6, 8, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 144, and 168 hrs post-dose | |
Secondary | To evaluate the safety of pacritinib and tolerability of a single 400-mg dose of pacritinib in patients with hepatic impairment and healthy subjects; | Adverse events, vital signs, physical examinations, clinical laboratory valuations, and ECGs | 00:00 of ICF signature until 1 min before IP admin and from the date-time of IP administration until 23:59 of the day of last contact |
