SAN DIEGO--(BUSINESS WIRE)--Capstan Therapeutics, Inc. (“Capstan”), a biotechnology company dedicated to advancing in vivo reprogramming of cells through RNA delivery utilizing targeted lipid nanoparticles (tLNP), today announced it will present preclinical data showing rapid and robust anti-tumor and anti-primary B cell activity in humanized mice by tLNP administration delivering an mRNA encoding an anti-CD19 chimeric antigen receptor (CAR), at the Society for Immunotherapy of Cancer (SITC) 38th Annual Meeting in San Diego, California.
“These data highlight the potential for Capstan’s targeted LNP-mRNA platform to provide a truly disruptive, off-the-shelf, cell-free, scalable and tunable solution for patients without the need for harsh lymphodepletion conditioning or viral vectors that are required for conventional ex vivo cell therapies,” said Adrian Bot, M.D., Ph.D., Capstan’s Chief Scientific Officer, and Executive Vice President of R&D. “We have demonstrated efficient and therapeutically relevant delivery of mRNA CAR payloads to human T cells. This resulted in rapid and profound pharmacodynamic effect in two mouse models, comprising eradication of human primary B cells or Nalm6 leukemic cells, respectively. These data provide a springboard for developing novel, in vivo CAR therapies that may overcome access and clinical performance issues with currently available ex vivo CAR therapies, with broad applicability in autoimmune and oncology indications.”
