About the Arcellx ddBCMA Cell Therapy Phase 1 Trial
CART-ddBCMA is a Phase 1 study of Arcellx’s BCMA-specific CAR-modified T-cell therapy utilizing the company’s novel BCMA-targeting binding domain for the treatment of patients with relapsed and refractory multiple myeloma. Arcellx’s proprietary binding domains—a central component of Arcellx’s ARC-sparX platform—are novel synthetic proteins engineered for reduced immunogenicity and designed to bind specific therapeutic targets. The Arcellx ddBCMA cell therapy has been granted Fast Track Designation and Orphan Drug Designation by the U.S. Food and Drug Administration. The Phase 1 study is currently enrolling patients. Additional information about the trial can be found at https://www.clinicaltrials.gov/ct2/show/NCT04155749.
About Arcellx’s ARC-sparX Platform Technology
The two-part ARC-sparX platform separates the disease recognition and killing functions of conventional cell therapies, enabling a controllable cell therapy that can be adapted to the patient’s disease. First, sparX proteins bind to specific antigens on diseased cells using a novel synthetic binding domain, then flag those cells for destruction by ARC-T cells. Next, ARC-T cells, which cannot recognize diseased cells on their own, bind to sparX proteins and kill the flagged cells. Arcellx has developed a collection of sparX proteins with unique binding domains directed at a number of therapeutic targets. Administration of alternate sparX proteins can redirect ARC-T cells to different disease antigens to potentially address relapsed and refractory disease due to tumor heterogeneity or antigen escape. ARC-T cell activity can be curbed as needed by controlling the dose and frequency of sparX administration, which has the potential to improve patient safety.
