A double-blind study to evaluate the effectiveness and safety of CAEL-101 in patients with AL amyloidosis.
EU CTIS ID: 2022-503072-84-00
What this study is testing
The primary objectives are: - To determine if CAEL-101 and treatment for plasma cell dyscrasia (PCD) improves overall survival and/or decreases the frequency of cardiovascular hospitalizations in Mayo stage IIIa AL amyloidosis patients who are treatment naïve compared to treatment for PCD and placebo; - To evaluate the safety and tolerability of CAEL-101 in combination with treatment for PCD and placebo
- Therapeutic confirmatory (Phase III)

Who can take part
You may be able to join if
- AL amyloidosis stage IIIa based on the European Modification of the 2004 Standard Mayo Clinic Staging who also have NT-proBNP ≥ 650 ng/L at the time of Screening
- 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) m-spike > 0.5 g/dL
- 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
- 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 AND 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
- Planned first-line treatment for plasma cell dyscrasia is cyclophosphamide-bortezomib-dexamethasone (CyBorD)-based regimen administered as SoC.
- Women of childbearing potential must have a negative pregnancy test during Screening and must agree to use highly effective contraception from Screening to at least 5 months following the last study drug administration or 12 months following the last dose of her PCD therapy, whichever is longer
You likely can't join if
- Have any other form of amyloidosis other than AL amyloidosis
- 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.
- 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, (eg, multiple myeloma and POEMS syndrome), specifically: i. Hypercalcemia: serum calcium > 0.25 mmol/L (> 1 mg/dL) higher than the ULN or > 2.75 mmol/L (> 11 mg/dL) OR ii. Renal insufficiency: creatinine clearance < 40 mL per minute or serum creatinine > 177 μmol/L (> 2 mg/dL) OR iii. Anemia: hemoglobin value of > 20 g/L below the lowest limit of normal, or a hemoglobin value < 100 g/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
- 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
