NCT06456346

Brief Summary

The purpose of this study is to evaluate the efficacy and safety of bomedemstat compared with hydroxyurea in cytoreductive therapy naïve essential thrombocythemia (ET) participants for whom cytoreductive therapy is indicated. Its primary objective is to compare bomedemstat to hydroxyurea with respect to durable clinicohematologic response (DCHR). The primary hypothesis is that bomedemstat is superior to hydroxyurea with respect to DCHR.

Outcome Measures

Primary Outcomes (1)

  • Durable Clinicohematologic Response (DCHR) Rate

    DCHR rate is the percentage of participants with DCHR, defined as a confirmed reduction of platelet count to ≤400 × 10\^9/L, absence of white blood cell (WBC) count elevation to \>10 × 10\^9/L locally assessed to be due to ET, starting by Week 24 and maintained for at least 24 weeks, and the absence of any thrombotic or major hemorrhagic events or disease progression to myelofibrosis (MF), myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) by Week 52.

    Up to Week 52

Secondary Outcomes (9)

  • Change From Baseline in Myelofibrosis Symptom Assessment Form version 4.0 (MFSAF v4.0) Individual Fatigue Symptom Item Score

    Baseline and pre-specified timepoints up to Week 52

  • Change From Baseline in Patient-reported Outcomes Measurement Information System (PROMIS) Fatigue SF-7a Total Fatigue Score

    Baseline and pre-specified timepoints up to Week 52

  • Change From Baseline in MFSAF v4.0 Total Symptom Score

    Baseline and Week 52

  • Duration of Hematologic Remission (DOHR)

    Up to Week 52

  • Number of Participants Who Experience Thrombotic Events

    Up to approximately 52 weeks

  • +4 more secondary outcomes

Study Arms (2)

Bomedemstat

EXPERIMENTAL

Participants will receive active bomedemstat and hydroxyurea placebo daily for up to approximately 52 weeks. Dosage will be adjusted either up or down within specified time parameters for each participant to the dose that provides sufficient exposure to safely inhibit thrombopoiesis to decrease platelet counts to the target range. Participants who complete treatment at Week 52 will be eligible to continue treatment in the extended treatment phase. Unblinding will occur and placebo discontinued once all participants have completed at least 52 weeks of therapy or otherwise discontinued.

Drug: BomedemstatDrug: Hydroxyurea placebo

Hydroxyurea

ACTIVE COMPARATOR

Dosage will be adjusted either up or down within specified time parameters for each participant to the dose that provides sufficient exposure to safely inhibit thrombopoiesis to decrease platelet counts to the target range. Participants who complete treatment at Week 52 will be eligible to continue treatment in the extended treatment phase. Unblinding will occur and placebo discontinued once all participants have completed at least 52 weeks of therapy or otherwise discontinued.
