Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Age ≥ 18 years
- Intermediate-1 or higher risk PMF, post-PV MF, or post-ET MF with evidence of minimum burden of disease based on splenomegaly, and for the monotherapy cohort, participants must have been previously treated with at least 1 JAK inhibitor for ≥ 12 weeks and resistant, refractory, intolerant to, or have lost response to JAK inhibitor treatment.
- For the MF SubOpt R cohort: Therapeutic regimen prior to enrollment as defined in the protocol and unlikely to benefit from further monotherapy in the opinion of the investigator.
- PV: Confirmed diagnosis of PV and previously treated with at least 1 prior standard cytoreductive therapy and are resistant, refractory, intolerant to, or have lost response to treatment.
- ET: Confirmed diagnosis of high-risk ET as defined in the protocol and previously treated with at least 1 prior standard cytoreductive therapy and are resistant, refractory, intolerant to, or have lost response to treatment.
- Life expectancy \> 6 months.
- Willingness to undergo a pretreatment and regular on-study bone marrow biopsies and aspirations (as appropriate to disease).
- Existing documentation of JAK2V617F mutation from a qualified local laboratory.
Exclusion criteria
- Presence of a hematological malignancy requiring treatment, other than PMF, post-PV MF, post-ET MF, PV, or ET.
- Prior history of major bleeding or thrombosis within the 3 months prior to study enrollment.
- Participants with abnormal hematologic, hepatic, or renal function based on laboratory evaluation.
- Has undergone prior allogenic or autologous stem-cell transplantation or allogenic stem-cell transplantation is planned
- Active invasive malignancy.
- Significant concurrent, uncontrolled medical condition.
- Acute or chronic HBV, active HCV or known HIV.
- Any prior MPN-directed therapy within 5 half-lives or 28 days (whichever is shorter) before the first dose of study treatment.
- Participants undergoing treatment with G-CSF or GM-CSF, romiplostim, or eltrombopag at any time within 4 weeks before the first dose of study treatment. Other protocol-defined Inclusion/Exclusion Criteria may apply.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
