Brief Title: Study of Chimeric Fibril-Reactive Monoclonal Antibody 11-1F4 in Patients With AL Amyloidosis
Official Title: Phase Ia/Ib Study of Chimeric Fibril-Reactive Monoclonal Antibody 11-1F4 in Patients With AL Amyloidosis
Study ID: NCT02245867
Brief Summary: The purpose of this study is to examine the tolerance, safety, pharmakinetics, and possible clinical benefit of the good manufacturing practice (GMP)-grade amyloid fibril-reactive chimeric (Ch) IgG1 mAb 11-1F4 in patients with amyloid light-chain (AL) amyloidosis. The phase 1a part will involve at least 3 patients and a maximum of 18 patients. The first patient will receive the starting dose of the antibody and, if tolerated, the following patients will each receive (if tolerated) progressively higher doses of the antibody. Patients in part 1a of the trial will receive only one infusion of the drug. Patients treated in the phase 1a part receive lower dosage which might not be effective. Once the maximal tolerated dosage is established during the phase 1a part, the investigators will accrue patients to the phase 1b part of the trial. Patients will receive 4 infusions, once each week for 4 weeks. Patients who were treated in the part 1a of the trial and showed no toxicity can be also treated in the part 1b of the trial. The first patient will receive the starting dose of the antibody and, if tolerated, the following patients will each receive (if tolerated) progressively higher doses of the antibody. When the investigators reach the maximum tolerated dose without toxicity, the investigators e will enroll another 4 patients to receive the same dose. If there are no toxicities, another 4 patients will be treated at the next dose level, and so forth. Patients treated in Phase 1b may receive lower dosages which might not be effective. The goal of Phase 1b is to establish the tolerance and possible beneficial effects of 11-1F4. If successful, treatment with this antibody would represent a novel approach in the care of individuals with AL amyloidosis.
Detailed Description: Presently, treatment of patients with amyloid light chain (AL) amyloidosis is limited to reducing production of the amyloid-forming light-chain protein by giving conventional or high-dose (with stem cell transplant) anti-plasma cell chemotherapy, as used for patients with multiple myeloma. Although this approach has extended survival, the prognosis remains poor due to the persistence or progression of the amyloid deposits in vital organs, such as the heart or kidney. A different treatment strategy would be to attempt to reduce and/or eliminate these deposits. This study evaluates this by administering an anti-amyloid monoclonal antibody, 11-1F4. This compound has been shown to reduce/destroy this material in an experimental animal model of amyloidosis.
