Presentation will feature new preclinical data of CPTx's proprietary immune-quiet DNA vector delivered non-virally with targeting lipid nanoparticles
Munich, Germany & San Francisco, California - October 20, 2026 - CPTx, a company developing next-generation non-viral in vivo CAR T therapies, today announced that it will present new findings from its preclinical studies at the 33rd Annual Congress of the European Society of Gene and Cell Therapy (ESGCT), taking place in Hamburg, Germany, from October 27-30, 2026.
The presentations will feature new efficacy data from rodent studies and first safety data from non-human primate (NHP) studies evaluating CPTx's fully non-viral in vivo CAR T platform. The platform combines proprietary immune-quiet hybrid DNA with targeted lipid nanoparticles (tLNPs) to program CAR T cells directly inside the patient.
Together, the new efficacy and safety data represent an important step in the platform's preclinical development toward clinical translation.
"Building on the encouraging preclinical evidence generated to date, we are focused now on translating our DNA-based in vivo CAR T platform toward first-in-human studies." - Hendrik Dietz, PhD, Founder and CEO of CPTx.
