Plain-language summary
This is a phase 1/2 trial of pacritinib in combination with azacitidine in patients with Chronic Myelomonocytic Leukemia (CMML). Patients will be newly diagnosed or previously treated but could not have received a prior JAK inhibitor. Patients who have previously been treated with a hypomethylating agent (HMA) must have received ≤ 1 cycle. Pacritinib will be initially tested at a dose of 200mg twice daily (dose level 0) in combination with azacitidine 75mg/m2, which can be administered subcutaneously or intravenously, for 7 days in a 28-day cycle. If there are 2 DLTs in the first 6 patients, there will be a dose escalation to pacritinib 100mg twice daily (dose level -1) and an additional 6 patients will be enrolled. Based on the phase 1, 3+3 dose de-escalation design, 6-12 patients will be enrolled in the phase 1 portion. After the completion of phase 1 and identification of the recommended phase 2 dose (RP2D), the trial will then proceed to phase 2 which will employ a Simon two stage design. This portion will include the 6 patients enrolled during the phase 1 portion at the MTD. An interim analysis for futility will occur. If 3 or fewer patients have had a clinical benefit (CB) or better, as defined by 2015 MDS/MPN IWG criteria, the PI and DSMC will meet to discuss the totality of the evidence and determine if the trial shall proceed. In the second stage, an additional 12 patients will be enrolled.

* Participants must have a pathologically confirmed diagnosis of chronic myelomonocytic leukemia per World Health Organization (WHO) or International Consensus Classification (ICC)
* Participants must be JAK inhibitor naïve.
* Participants may be hypomethylating agent (HMA) naïve or can be treated with up to one prior cycle.
* Participants must have either proliferative CMML (WBC ≥13 x 109/L) or have intermediate-2 or high risk CMML by the clinical/molecular CMML-specific prognostic scoring system (CPSS-Mol).

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
