入选标准

  • Key Inclusion Criteria:
  • 1. AL amyloidosis stage IIIb based on the European Modification of the 2004 Standard Mayo Clinic Staging at the time of Screening
  • 2. Measurable hematologic disease at Screening as defined by at least one of the following:
  • a . Involved/uninvolved free light chain difference (dFLC) > 4 mg/dL or
  • b. Involved free light chain (iFLC) > 4 mg/dL with abnormal Kappa/Lambda ratio or
  • c. Serum protein electrophoresis (SPEP) > 0.5 g/dL
  • 3. Histopathological diagnosis of amyloidosis based on polarizing light microscopy of green bi-refringent material in Congo red
  • stained tissue specimens AND confirmation of AL derived amyloid deposits by at least one of the following:
  • a. Immunohistochemistry/Immunofluorescence or
  • b. Mass spectrometry or
  • c. Characteristic electron microscopy appearance/Immunoelectron microscopy
  • 4. Cardiac involvement as defined by:
  • a. Documented clinical signs and symptoms supportive of a diagnosis of heart failure in the setting of a confirmed diagnosis of AL
  • amyloidosis in the absence of an alternative explanation for heart failure
  • b. At least one of the following:
  • I. Endomyocardial biopsy demonstrating AL cardiac amyloidosis or
  • ii. Echocardiogram demonstrating a mean left ventricular wall thickness (calculated as [IVSd+LPWd]/2) of > 12 mm at diastole in the absence of other causes
  • (e.g., severe hypertension, aortic stenosis), which would adequately explain the degree of wall thickening or
  • iii. Cardiac magnetic resonance imaging (MRI) with gadolinium contrast agent diagnostic of cardiac amyloidosis
  • 5. Planned first-line treatment for plasma cell dyscrasia is cyclophosphamide-bortezomib-dexamethasone (CyBorD)-based regimen administered
  • 6. Women of childbearing potential (WOCBP) must have a negative pregnancy test during Screening and must agree to use highly effective contraception
  • (Section 6.9) from Screening to at least 5 months following the last study drug administration or 12 months following the last dose of her anti-PCD therapy, whichever is longer
  • 7. Men must be surgically sterile or must agree to use highly effective contraception (Section 6.9) and refrain from donating sperm
  • from Screening to at least 5 months following the last study drug administration or 12 months following the last dose of their PCD
  • therapy, whichever is longer
  • Are the trial subjects under 18? no
  • Number of subjects for this age range:
  • F.1.2 Adults (18-64 years) yes
  • F.1.2.1 Number of subjects for this age range 74
  • F.1.3 Elderly (>=65 years) yes
  • F.1.3.1 Number of subjects for this age range 50

排除标准

  • Key Exclusion Criteria:
  • 1. Have any other form of amyloidosis other than AL amyloidosis
  • 2. Received prior therapy for AL amyloidosis or multiple myeloma. A maximum exposure of 2 weeks of a CyBorD-based PCD treatment after Screening laboratory samples are obtained and prior to randomization is allowed.
  • 3. Has POEMS syndrome or multiple myeloma defined as clonal bone marrow plasma cells > 10% from a bone marrow biopsy (performed = 3 months prior to signing the ICF or during screening) or biopsy-proven (performed = 3 months prior to signing the ICF or during screening) bony or extramedullary plasmacytoma AND any one or more of the following CRAB features:
  • a. Evidence of end organ damage that can be attributed to the underlying plasma cell proliferative disorder, specifically:
  • i. Hypercalcemia: serum calcium > 0.25 mmol/L (> 1mg/dL) higher than the upper limit of normal (ULN) or > 2.75 mmol/L (> 11mg/dL) OR
  • ii. Renal insufficiency: creatinine clearance < 40 mL per minute or serum creatinine > 177mol/L (> 2mg/dL) OR
  • iii. Anemia: hemoglobin value of > 20g/L below the lowest limit of normal, or a hemoglobin value < 100g/L OR
  • iv. Bone lesions: one or more osteolytic lesion on imaging tests (performed = 3 months prior to signing the ICF or during screening): skeletal radiography, CT, or PET/CT, or MRI. If bone marrow has < 10% clonal plasma cells, more than one bone lesion is required to distinguish from solitary plasmacytoma with minimal marrow involvement OR
  • b. Any one of the following biomarkers of malignancy:
  • i. 60% or greater clonal plasma cells on bone marrow examination OR
  • ii. More than one focal lesion on MRI that is at least 5mm or greater in size
  • 4. Have supine systolic blood pressure < 90 mmHg or symptomatic orthostatic hypotension, defined as a decrease in systolic blood pressure upon
  • standing of > 30 mmHg despite medical management (e.g., midodrine, fludrocortisones) in the absence of volume depletion
