About this study
Official title: A Phase 1, Open-Label, Single-Dose, Randomized, 2-Period, 2-Treatment-Sequence Crossover Study to Assess the Relative Bioavailability of Pacritinib Following Oral Administration as Capsule and Solution Formulations in Healthy Subjects
This was a randomized, 2-period, 2-treatment-sequence crossover study to determine the relative bioavailability of pacritinib following administration as a 400 mg oral dose of four 100 mg pacritinib capsules and an 80 mg dose of an oral solution and to characterize the PK and major human metabolites of pacritinib.
Read the detailed description
Twelve healthy subjects will be enrolled in the study (6 subjects per sequence) at a single clinical site with the intent that 12 subjects complete Periods 1 and 2 in the study. Subjects will be randomly assigned to 2 possible sequences (6 subjects per sequence) on Day 1 of Period 1. Subjects will be randomly assigned to 2 possible sequences. Each subject received 2 treatments (a 400 mg oral dose of four 100 mg pacritinib capsules and an 80 mg oral solution dose of pacritinib) in a 2-period crossover design. Each treatment will be administered as monotherapy during 1 of 2 treatment periods with a 7-day washout period between administrations of each study medication.

What is being measured
The primary outcome is the main question the study is designed to answer.
The maximum plasma concentration (Cmax)
For each subject, the following PK parameters were calculated, whenever possible, based on the plasma concentrations of pacritinib and pacritinib M1 metabolite, using noncompartmental methods.
Measured: Plasma: 0, 1, 2, 4, 6, 8, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 144, and 168 hrs post-dose
The area under the plasma concentration-time curve from time zero to time of the last measured concentration above the limit of quantification (AUC0-t)
For each subject, the following PK parameters were calculated, whenever possible, based on the plasma concentrations of pacritinib and pacritinib M1 metabolite, using noncompartmental methods.
Measured: Plasma: 0, 1, 2, 4, 6, 8, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 144, and 168 hrs post-dose
The time to reach maximum plasma concentration (tmax)
For each subject, the following PK parameters were calculated, whenever possible, based on the plasma concentrations of pacritinib and pacritinib M1 metabolite, using noncompartmental methods.
Measured: Plasma: 0, 1, 2, 4, 6, 8, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 144, and 168 hrs post-dose
The area under the plasma concentration-time curve from zero to infinity (AUC0-∞)
For each subject, the following PK parameters were calculated, whenever possible, based on the plasma concentrations of pacritinib and pacritinib M1 metabolite, using noncompartmental methods.
Measured: Plasma: 0, 1, 2, 4, 6, 8, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 144, and 168 hrs post-dose
Area under the effect-time curve from Hour 0 to the last measurable activity level
For each subject, the following PD parameters were calculated, whenever possible, based on the stimulated pSTAT3/unstimulated Total STAT3 ratio in PBMCs, using noncompartmental methods

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing (Treatment A) and (Treatment B) in people with Healthy Subjects, run by CTI BioPharma at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The maximum plasma concentration (Cmax) (time frame: Plasma: 0, 1, 2, 4, 6, 8, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 144, and 168 hrs post-dose). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Sep 2023.
