Increased levels of TGF-β1 were detected in serum, plasma and BM and positively correlated with both grade of BMF and extent of leukemic cell infiltration in the marrow. TGF-β likely plays a dual role in promoting myelofibrosis and myeloproliferation, both of which are the bone marrow morphologic hallmark of MF. AVID200 is a drug that targets TGF-β1 and TGF-β3. The study team hypothesizes that inhibiting the TGF-β signaling pathway in MF will decrease the fibrogenic stimuli leading to myelofibrosis and concomitantly interrupt myeloproliferation and restore normal hematopoiesis.
This is a first in human, open-label, multicenter, Phase I/Ib trial of AVID200. Patients must have intermediate-2 or higher primary myelofibrosis (PMF), post-essential thrombocythemia or polycythemia-vera related MF (Post ET/PV MF). This study will enroll up to 24 patients. AVID200 is delivered by IV infusion on day 1 of each 3 week cycle.

intravenous in dose cohorts of 70mg/m2 or 180 mg/m2
dose cohorts of 21-day cycles
- Maximally tolerated dose (MTD) of AVID200 [ Time Frame: After 6 cycles (Each cycle is 21 days) ]Cohorts of 3 patients with a maximum evaluable sample size of 12 patients and a target toxicity rate of 30% to estimate the MTD. Each cycle is 21 days.
- Number of patients with response eligibility for Phase 1b [ Time Frame: After 6 cycles ]Subjects attaining at least a CI (clinical improvement) by IWG/ELN criteria, or a decrease in bone marrow fibrosis by ≥1 grade with otherwise stable disease, will be allowed to continue AVID200 in the extension phase of the trial.
- IWG/ELN criteria [ Time Frame: After 6 cycles and after 12 cycles (Each cycle is 21 days) ]response by IWG/ELN criteria at the end of Cycle 6 and Cycle 12. The IWG/ELN criteria: CR (complete remission), PR (partial remission), Clinical improvement, Anemia response, Spleen response, Symptoms response, PD (progressive disease), SD (stable disease), Relapse, Cytogenetic remission, and Molecular remission
- Bone marrow fibrosis grade [ Time Frame: up to 37 days after 13 cycles (Each cycle is 21 days) ]bone marrow fibrosis grade at the end of Cycle 6 and 12. Bone marrow fibrosis (MF) is graded as MF-0 to MF-3, with higher number indicating more disease.
- Myelofibrosis Symptom Assessment Form (MFSAF) [ Time Frame: up to 37 days after 13 cycles (Each cycle is 21 days) ]MF-SAFv4.0,each of the items are scored 0 to 10, with total summation from 0 to 100, with higher score indicating more symptoms.
- EORTC QLQ-C30 [ Time Frame: up to 37 days after 13 cycles (Each cycle is 21 days) ]EORTC QLQ-C30, 28 item scored from 1 (not at all) to 4 (very much), and 2 items scored 1 (very poor) to 7 (excellent). Total score from 28 - 126, with higher score indicating poorer health
