Pacritinib With Aza for Upfront Myelodysplastic Syndrome
25 participantsStarted 2026-07
Plain-language summary
This study will be conducted as a phase 1/2 study of safety and preliminary efficacy of pacritinib in combination with azacitidine for IPSS-M moderate low to very high risk MDS. Phase one will be a 3 + 3 design to assess the dose for the phase two portion. The phase two portion will employ a simon min-max two-stage design whereby fifteen patients will be enrolled in the first stage then ten more if at least two patients in stage one have a response. The dosing of pacritinib for the phase two study will be based on the phase one findings. Standard dosing of azacitidine will be used. A correlative study will be conducted in conjunction with the trial where the investigators will measure whole blood collected pre-treatment and at four days post-treatment to measure intracellular flow and phosflow to detect JAK/STAT, NF-κβ, and AKT/mTOR signaling in patient samples and how treatment affects these pathways.

Inclusion criteria
. Patients must have histologic evidence of intermediate to high-risk myelodysplastic syndrome defined as having an IPSS-M score of moderate low, moderate high, high or very high risk. This will be assessed based on evaluations performed prior to screening for trial. Of note, the most recent evaluation pre-trial may be used which does not have to necessarily be at diagnosis.
. Subjects must have recovered from the toxic effects of any prior chemotherapy to ≤ Grade 1 (except alopecia).
. Required screening visit laboratory values: CrCL ≥45; total bilirubin \<2xULN except for patients with known Gilbert's disease; SGPT (ALT) ≤2xULN, PTT ≤1.5xULN.
. Negative pregnancy test for women with child-bearing potential at screening visit.
. Initial screening baseline QTc ≤480ms.
. Patients must be able to sign consent and be willing and able to comply with scheduled visits, treatment plan and laboratory testing.
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.
What they're measuring
1
Optimal Dose of Pacritinib in Combination with Azacitidine - Phase 1
Timeframe: Baseline through Day 28 (Cycle 1)
2
Rate of Dose Limiting Toxicities (DLTs) - Phase 1
Timeframe: Baseline through Day 28 (Cycle 1)
3
Overall Response Rate (ORR) - Phase 2
Timeframe: Baseline through Week 16 (approximately 4 months)
. Patients must have an absolute neutrophil count of ≥750 to enroll in study, this must be achieved without the addition of growth factor medication.
Exclusion criteria
. Any prior exposure to a hypomethylating agent (azacitidine or decitabine)
. Any prior exposure to JAK2 inhibitor therapy (ie ruxolitinib or prior pacritinib therapy)
. Any exposure within the past seven days of initiation of study treatment to a strong CYP3A inhibitor/inducer.
. Subjects must not be receiving any chemotherapy agents (except hydroxyurea) within the past thirty days.
. Subjects must not be receiving growth factors (erythropoietin mimetics, granulocyte stimulating factor mimetics, thrombopoietin mimetics) for two weeks prior to enrollment bone marrow. Subjects may not receive growth factors for the duration of this study.
. Subjects with a "currently active" second malignancy, other than curatively treated non-melanoma skin cancer, carcinoma in situ of the cervix, resected incidental prostate cancer (staged pT2 with Gleason Score ≤ 6 and postoperative PSA \<0.5 ng/mL), or other adequately treated carcinoma-in-situ are eligible. Patients are not considered to have a "currently active" malignancy if they have completed therapy and are free of disease for ≥ 1 year.
. Subjects with uncontrolled high blood pressure, unstable angina, symptomatic congestive heart failure (NYHA class 2), myocardial infarction within the past 6 months or serious uncontrolled cardiac arrhythmia are not eligible.
. Bleeding event grade \>=2 (CTCAE 5.0) within prior three months unless provoked (e.g., by surgery or trauma)
