Momelotinib targets JAK1/JAK2 and ACVR1, improving anemia and splenomegaly. However, a proportion of patients fail to achieve adequate spleen, symptom, or hematologic improvement.\n\nBomedemstat, an irreversible LSD1 inhibitor, may:\n\n* Modify megakaryocyte function\n* Reduce fibrosis\n* Improve cytokine dysregulation\n* Impact stem/progenitor dynamics Sequential introduction of Bomedemstat at Week 12 allows assessment of Momelotinib's initial stabilizing effect and evaluates whether LSD1 inhibition can rescue suboptimal responders without compromising hematologic tolerability.\n\nSTUDY DURATION\n\n* Screening: Up to 28 days\n* Momelotinib monotherapy: Weeks 0-12\n* Bomedemstat + Momelotinib combination: Weeks 12-24\n* Primary endpoint assessment: Week 24\n* Safety follow-up: 30 days post last dose\n* Long-term follow-up: Every 12 weeks for up to 12 months Total participation duration per patient: Approximately 14-16 months\n\nNUMBER OF PARTICIPANTS Approximately 40 participants will be enrolled across multiple international sites. This sample size provides adequate precision for estimation of the primary endpoint (SVR35) and is consistent with exploratory Phase 2 combination studies.\n\nINVESTIGATIONAL PLAN OVERVIEW\n\n1. Screening Procedures\n\n o Informed consent\n\n o Medical history, physical exam\n * Hematology, chemistry, thyroid function\n * Bone marrow biopsy (if unavailable within 6 months)\n * Spleen volume imaging (MRI or CT)\n * MPN-SAF Total Symptom Score\n * ECG, urinalysis\n * Eligibility confirmation\n2. Intervention Procedures Weeks 0-12\n\n o Momelotinib 200 mg QD alone\n\n o Hematologic monitoring\n * Week 12 response assessment Weeks 12-24\n * Bomedemstat 50 mg QD added\n * Titration per MF-specific rules (standard tables retained verbatim)\n * Weekly CBCs during first 4 weeks of combination\n * MRI/CT at Week 24\n3. Follow-Up Procedures o 30-day safety follow-up\n\n o Every 12-week long-term survival and disease progression follow-up\n\n STUDY SCHEMA (REQUIRED BY THE FIRST FILE) Screening (≤ 28 days)\n\n ↓ Momelotinib Alone (Weeks 0-12)\n * Week 12 Response Assessment If Suboptimal → Add Bomedemstat 50 mg QD\n\n Combination Phase (Weeks 12-24) ↓ Week 24 Primary Endpoint Assessment ↓ Safety Follow-Up (30 days post last dose)\n\n ↓ Long-Term Follow-Up (q12 weeks for 12 months)"}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '99 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* 1\\.
