Descriptive Information
Brief Title  ICMJE MPN-RC 118 AVID200 in Myelofibrosis
Official Title  ICMJE Phase I Study of AVID200 in Patients With Myelofibrosis (Myeloproliferative Neoplasms Research Consortium [MPN-RC] 118)
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.

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.

Eligibility Criteria  ICMJE

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.
  • Life expectancy of at least six months
  • At least two weeks must have elapsed between the last dose of any MF-directed drug treatments (including investigational therapies and excluding hydroxyurea) and study enrollment
  • Not eligible for ruxolitinib therapy due to a platelet count <50 x 109/L, previously treated and lack/loss of response as defined by at least one of the following:

    1. Treatment for ≥3 months with inadequate efficacy response defined as <10% spleen volume reduction by MRI or <30% decrease from baseline in spleen length by physical examination or regrowth to these parameters following an initial response; and/or
    2. Treatment for ≥28 days complicated by either

    i. Development of a red blood cell transfusion requirement (at least 2 units/month for 2 months) ii. National Cancer Institute (NCI) CTCAE grade ≥ 3 AEs of thrombocytopenia, anemia, hematoma, and/or hemorrhage while being treated with a dosage of < 20 mg BID

  • Recovery to ≤ Grade 1 or baseline of any toxicities due to prior systemic treatments, excluding alopecia

  • Must have adequate organ function as demonstrated by the following:

    1. ALT (SGPT) and/or AST (SGOT) ≤ 3x upper limit of normal (ULN), or ≤ 4 x ULN (if upon judgment of the treating physician, it is believed to be due to extramedullary hematopoiesis [EMH] related to MF);

  • Presence of active serious infection;
  • Any serious, unstable medical or psychiatric condition that would prevent, (as judged by the Investigator) the subject from signing the informed consent form or any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study

  • Organ transplant recipients other than bone marrow transplant
