Brief Summary:

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.


Condition or disease Intervention/treatment Phase
Primary Myelofibrosis Post-essential Thrombocythemia Myelofibrosis Post-polycythemia Vera Myelofibrosis Post ET MF Post PV MF Drug: AVID200 Phase 1

Detailed Description:
This is a first in human, open-label, multicenter, Phase I/Ib trial of AVID200. To date, there is no therapy for MF evaluated in the clinic that clearly demonstrates the ability to target the malignant HSC and result in effective and reproducible bone marrow morphologic, cytogenetic and molecular responses. Medicinal therapies that result in disease course modification are urgently needed in this chronic and progressive myeloid malignancy. TGF-β likely plays a dual role in promoting myelofibrosis and myeloproliferation, both of which are the bone marrow morphologic hallmark of MF. The study team proposes 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. AVID200 is a fusion protein containing TGF-β receptor ectodomains fused to a human Fc IgG domain. AVID200 is a potent TGFβ trap with antibody-like properties which has pM potency against two of the three TGFβ ligands, TGFβ1 and β3.

Primary Outcome Measures :
  1. 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.

  2. 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.


Secondary Outcome Measures :
  1. 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

  2. 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.

  3. 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.

  4. 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

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Subjects must be ≥18 years of age at the time of signing the Informed Consent Form (ICF)
  • Subjects must voluntarily sign an ICF
  • Subjects must have a pathologically confirmed diagnosis of PMF as per the WHO diagnostic criteria or post ET/PV MF (note that all diagnoses must include the presence of at least Grade 2 marrow fibrosis according to the European Consensus on Grading of Bone Marrow Fibrosis (see Table 6) with intermediate -2 or high risk disease according to the IWG-MRT Dynamic International Prognostic Scoring System (DIPSS) (see Table 7)
  • A bone marrow biopsy must be performed within the 30 day screening period, however, a bone marrow biopsy obtained within 90 days of screening without intervening treatments and approved by the study chair may suffice.
  • Subjects must have an Eastern Cooperative Oncology Group (ECOG) Performance Status of 0-2.
