简要总结
TGF-β is a cytokine that is found to be upregulated in the bone marrow of patients with myelofibrosis. This cytokine likely plays a dual role in promoting myelofibrosis and myeloproliferation, both of which are the bone marrow morphologic hallmark of MF. The investigators propose that inhibiting the TGF-β signaling pathway in MF will decrease the fibrogenic stimuli leading to myelofibrosis and concomitantly interrupt myeloproliferation. This is a novel approach to the treatment of patients with myelofibrosis.

入选标准
- •Intermediate-1 or higher by IWG-MRT Post PV/ET MF patients OR intermediate-1 or higher JAK2V617F negative PMF
- •Bone marrow MF-2 or higher as assessed by the European consensus grading score AND grade 3 or higher by modified Bauermeister scale.
- •Patients must be able to give written informed consent to participate. Patients may not be consented by a durable power of attorney.
- •Male and female patients of child-producing potential must agree to use effective contraception while enrolled on study and receiving the investigational agent, and for at least 3 months after the last treatment.
- •At the time of enrollment, patients must be >4 weeks since major surgery, radiotherapy, chemotherapy (except hydroxyurea) immunotherapy, or biotherapy/targeted therapies and recovered from the toxicity of prior treatment to < Grade 1, exclusive of alopecia. Concurrent cancer therapy is not permitted for the exception of hydroxyurea if already being used at a stable dose for 3 weeks prior to screening.
- •Patients must have negative tests for human immunodeficiency virus (HIV) and for hepatitis viruses B and C (antibody and/or antigen) unless the result is consistent with prior vaccination or prior infection with full recovery.
- •Marrow: Absolute neutrophil count ≥ 500/mm3, and platelet count ≥50,000/mm3 without the need for platelet transfusion within 4 weeks
- •Hepatic: Serum total bilirubin >1.5 X upper limit of normal (ULN) (Patients with Gilbert's Disease may be included if their total bilirubin is >3.0 mg/dL); alanine aminotransferase (ALT), and aspartate aminotransferase (AST) >2.5 X ULN.
- •Renal: Serum creatinine of < 1.5 x upper limit of normal (ULN) or, if higher, estimated or measured creatinine clearance >45 mL/min.
- •Coagulation:
- •Prothrombin Time (PT) < 1.5 X ULN
- •Partial thromboplastin time (aPTT) < 1.5 X ULN
排除标准
- •Central nervous system (CNS) cancer or metastases, meningeal carcinomatosis, malignant seizures, or a disease that either causes or threatens neurologic compromise (e.g., unstable vertebral metastases).
- •Pregnant or nursing women, due to the unknown effects of GC1008 on the developing fetus or newborn infant.
- •Patients with known bleeding diathesis or signs of uncontrolled active bleeding (hematuria, GI bleeding) other than self-limited causes of benign etiology that have been adequately investigated at the discretion of the investigator.
- •Patients requiring anticoagulation with aspirin > 81mg daily, unfractionated heparin, low molecular weight heparin (LMWH), direct anti-thrombin inhibitors, or vitamin K antagonists (e.g. warfarin). This does not apply to patients actively receiving aspirin at a dose of ≤ 81mg a day.
- •Patients diagnosed with another malignancy - unless following curative intent therapy, the patient has been disease free for at least 5 years and the probability of recurrence of the prior malignancy is >5%. Patients with curatively treated early stage squamous cell carcinoma of the skin, basal cell carcinoma of the skin, or cervical intraepithelial neoplasia (CIN) are eligible for this study.
- •Patients with an organ transplant, including those that have received an allogeneic bone marrow transplant.
- •Use of investigational agents within 4 weeks prior to study enrollment (within 6 weeks if the treatment was with a long-acting agent such as a monoclonal antibody).
- •Significant or uncontrolled medical illness, such as congestive heart failure (CHF), myocardial infarction, symptomatic coronary artery disease, significant ventricular arrhythmias within the last 6 months, or significant pulmonary dysfunction. Patients with a remote history of asthma or active mild asthma may participate.
- •Active autoimmune disorders or concurrent immunosuppressive medications such as prednisone, interferon, cyclosporine, methotrexate or azathioprine.
- •Active infection requiring antibiotics.
- •A known allergy to any component of GC
- •Patients who, in the opinion of the Investigator, have significant medical or psychosocial problems that warrant exclusion. Examples of significant problems include, but are not limited to:
- •Other serious non-malignancy-associated medical conditions that may be expected to limit life expectancy or significantly increase the risk of SAEs.
- •Any condition, psychiatric, substance abuse, or otherwise, that, in the opinion of the Investigator, would preclude informed consent, consistent follow-up, or compliance with any aspect of the study
结局指标

Safety and Tolerability
时间窗: 28 days
To assess the safety and tolerability of GC1008 in patients with primary myelofibrosis (PMF) or post-polycythemia vera/essential thrombocythemia myelofibrosis (Post-PV/ET MF). A total of 9 AEs determined by the investigator to be at least possibly related to GC1008 occurred during the study.
