Description:
A Phase 3, randomized, blinded study comparing CPI-0610 and ruxolitinib with placebo and
ruxolitinib in myelofibrosis (MF) patients that have not been exposed previously to Janus
kinase inhibitors (JAKi). CPI-0610 is a small molecule inhibitor of bromodomain and
extra-terminal (BET) proteins. Evidence suggests that inhibition of both BET and JAK pathways
can result in synergistic reduction of disease and overall improvement in the prognosis of
MF.

Eligibility Criteria
Inclusion Criteria:
- Aged ≥ 18 years
- Confirmed diagnosis of myelofibrosis (primary, post-polycythemia vera, or post
essential thrombocythemia)
- Adequate hematologic, renal, and hepatic function
- Have at least 2 symptoms with an average score ≥ 3 or an average total score of ≥ 10
over the 7-day period prior to randomization using the MFSAF v4.0
- Prognostic risk-factor score of Intermediate-1 or higher per Dynamic International
Prognostic Scoring System (DIPSS) scoring system
- Spleen volume of ≥ 450 cm^3
- Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2
Exclusion Criteria:
- Splenectomy or splenic irradiation in the previous 6 months
- Chronic or active conditions and/or concomitant medication use that would prohibit
treatment
- Had prior treatment with any JAKi or BET inhibitor for treatment of a
myeloproliferative neoplasm
Maximum Eligible Age: | N/A |
Minimum Eligible Age: | 18 Years |
Eligible Gender: | All |
Healthy Volunteers: | No |
Primary Outcome Measures
Measure: | Splenic response at Week 24 |
Time Frame: | 24 weeks of treatment |
Safety Issue: | |
Description: | The primary endpoint of the study is splenic response, defined as a ≥35% reduction from baseline in spleen volume as measured by magnetic resonance imaging (MRI) or computerized tomography (CT), at Week 24. |
Secondary Outcome Measures
Measure: | Total Symptom Score response at Week 24 |
Time Frame: | 24 weeks of treatment |
Safety Issue: | |
Description: | The key secondary endpoint of the study is Total Symptom Score response, defined as a ≥50% decrease from baseline in Total Symptom Score as measured by the Myelofibrosis Symptom Assessment Form v4.0, at Week 24. A higher Total Symptom Score indicates a higher disease burden and thus a worse outcome. |
