Clinical Trial Summary

This is an open-label, parallel-group, single-dose study of the PK and safety of 400 mg pacritinib administered orally to patients with stable chronic liver disease and healthy control subjects.


Description:

All study participants will undergo screening evaluations to determine eligibility for the study. All screening evaluations must be performed within 28 days of pacritinib dosing (Day 1). Assignment of patients to each hepatic impairment group will be defined by Child-Pugh Clinical Assessment Score at the time of Screening. Group 3 patients will not be dosed until at least 2 patients combined from Groups 1 and 2 have completed the study (Day 8). Healthy subjects will be enrolled after hepatic impairment accrual is complete to allow for age-, gender- and body mass index- (BMI) matching with the hepatic impairment population. Participants will be admitted to the study site on Day -1 (i.e., Check-in). On Day 1, upon receipt of all baseline safety evaluation results and confirmation of eligibility, study participants will be administered a single dose of 400 mg pacritinib orally under fasting conditions. Fasting will start 10 hours prior to pacritinib administration and continue for an additional 4 hours after administration. Following administration of pacritinib, participants will remain confined to the study site for 168 hours (8 days) after pacritinib dosing for collection of blood for PK and safety assessments.

Outcome

Type Measure Description Time frame Safety issue
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
