Summary
Brief summary (as posted)
AL amyloidosis begins in the bone marrow where abnormal proteins misfold and create free light chains that cannot be broken down. These free light chains bind together to form amyloid fibrils that build up in the extracellular space of organs, affecting the kidneys, heart, liver, spleen, nervous system and digestive tract. The primary purpose of this study is to determine the recommended dose of CAEL-101 to facilitate progression of further clinical trials and evaluate safety and tolerability of CAEL-101 in combination with the standard of care (SoC) cyclophosphamide-bortezomib-dexamethasone (CyBorD) chemotherapy and daratumumab .

- label
- Part A: CAEL-101 combined with SoC CyBorD
- description
- CAEL-101 is administered as an intravenous (IV) infusion over approximately 2 hours. The initial cohort dose assignments of CAEL-101 will be: Cohort 1 - 500 mg/m\^2 Cohort 2 - 750 mg/m\^2 Cohort 3 - 1000 mg/m\^2. CAEL-101 will be administered weekly for the first 4 weeks, and then every other week until end of study, in combination with the SoC CyBorD chemotherapy. Patients will be treated until death, unacceptable toxicity, symptomatic deterioration, Investigator decision, patient decision or Sponsor decision to terminate the study. Patients from Part A who are in the Continued Treatment Period and who, in the Investigator's judgment, should have their SoC treatment complemented with daratumumab may do so (Part B).

- Part B: CAEL-101 combined with SoC CyBorD and daratumumab
- description
- CAEL-101 is administered as an intravenous (IV) infusion at the RP3D dose level. CAEL-101 will be administered weekly for the first 4 weeks, and then every other week until end of study, in combination with the SoC CyBorD chemotherapy and daratumumab. After completing approximately 50 weeks of treatment, participants may switch to an alternative maintenance dosing regimen of every four weeks (q4wk), if agreed upon by the Investigator and the Sponsor Medical Monitor. Patients will be treated until death, unacceptable toxicity, symptomatic deterioration, Investigator decision, patient decision or Sponsor decision to terminate the study.

Key Inclusion Criteria: Each patient must meet the following criteria to be enrolled in this study. 1. AL amyloidosis Mayo stage I, II or IIIa 2. For Part A only, measurable hematologic disease defined by at least one of the following: 1. involved/uninvolved free light chain difference (dFLC) \> 5mg/dL or 2. free light chain (FLC) \> 5mg/dL with abnormal Kappa/Lambda ratio or 3. serum protein electrophoresis (SPEP) m- spike \> 0.5 g/dL Patients with confirmed AL amyloid diagnosis without measurable disease may be enrolled with consultation and approval by the Sponsor Medical Monitor or their designee. 3. a. For Part A, currently on and continuing OR planned to start concurrent chemotherapy with CyBorD administered weekly as SoC. b. For Part B, currently on and continuing OR planned to start concurrent chemotherapy with CyBorD and daratumumab administered as SoC. Key Exclusion Criteria: Patients who meet any of the following criteria will not be permitted entry to the study. 1. Any form of secondary, hereditary, senile, localized, dialysis-related or leukocyte chemotactic factor 2-related (ALECT2) amyloidosis 2.

Receiving dialysis 5. Myocardial infarction, uncontrolled angina, severe uncontrolled ventricular arrhythmias, or percutaneous cardiac intervention with recent stent, coronary artery bypass grafting or major cerebrovascular accident within 6 months prior to screening 6. Left ventricular ejection fraction (LVEF) \< 45 percent by echocardiogram or multigated acquisition scan (MUGA)
