BCMA/GPRC5D Trispecific Antibody Treatment for Newly Diagnosed Amyloidosis (AL-004)

Systemic light-chain (AL) amyloidosis is a plasma cell disorder characterized by the production of misfolded immunoglobulin light chains that deposit in organs and lead to progressive organ dysfunction. Although daratumumab-based therapy has improved outcomes, a substantial proportion of patients fail to achieve deep hematologic responses. This is a prospective, single-arm, single-center clinical study evaluating the safety and efficacy of the BCMA/GPRC5D/CD3 trispecific antibody QLS4131 in patients with newly diagnosed systemic AL amyloidosis.
