T cell therapies are only as good as the cells that reach the patient, yet ex vivo manufacturing itself drives exhaustion and erodes the stem-like memory phenotypes that underpin durable response. We have built an AI-driven discovery platform that predicts novel intracellular targets and designs small molecules to address this at its source. Added during ex vivo expansion and washed out before infusion, these compounds act as manufacturing reagents rather than systemic drugs, allowing integration under a sponsor's existing IND without a standalone regulatory filing. In primary human T cells, our lead compound drives a roughly 16-fold increase in polyfunctionality, a twofold enrichment of stem-like memory cells, elevated TCF-1, and reduced exhaustion. Because the approach is target-driven and platform-based, it is modality-agnostic across CAR-T and next-generation cell therapies.
Summary:
Discover new data demonstrating a streamlined approach to gene-modified T cell manufacturing that integrates multiple critical unit operations into a single, closed workflow. This webinar will present the first demonstration of incorporating T cell isolation upstream of Quantum Flex™ processing, extending automation and process integration from cell selection through expansion.
Starting with Leukopak material collected on the Spectra Optia®, CD3+ T cells were isolated using a buoyancy-based microbubble separation method. Fewer than 10 million isolated and activated T cells were then directly introduced into the Quantum Flex system, where they underwent lentiviral transduction and expansion to a therapeutically relevant dose.
Key Takeaways:
Join us to explore how an integrated, closed-system workflow could help advance cell therapy manufacturing through greater efficiency, flexibility, and process consistency.
Abstract: Serum is a major source of variability in T cell manufacturing, driving lot-to-lot inconsistency, sourcing constraints, and contamination risk. This data-led session shows you how a chemically defined, serum-free workflow removes that dependency, so you can build more reproducible processes from early development through clinical scale.
This presentation examines experimental data on the impact of serum removal at each stage of manufacturing: improved lentiviral vector transduction efficiency, robust T cell expansion in serum-free culture, and clinical-scale performance across multiple platforms. You will see cross-platform results spanning T-flasks, G-Rex, Xuri, and Cocoon systems, plus practical evidence on how oxygen transfer and media exchange strategies shape expansion outcomes. Key points takeaways include:
In vivo CAR therapy is emerging as a transformative approach that enables direct immune cell engineering within patients using delivery platforms such as lentiviral vectors (LVVs) and lipid nanoparticles (LNPs). While recent clinical advances have validated the potential of this modality, significant challenges remain in achieving efficient cell-specific delivery, characterizing delivery vehicles, and monitoring CAR expression. To address these needs, ACROBiosystems has developed an integrated platform to support the development and evaluation of targeted in vivo CAR therapeutics. The platform combines immune cell-targeting binder discovery, quantitative characterization of antibody-decorated LNPs, assessment of cellular uptake and intracellular trafficking, and sensitive CAR detection using fluorescently labeled recombinant proteins, anti-idiotypic antibodies, and universal CAR detection reagents. Our studies demonstrate that functional ligand accessibility, rather than total ligand density alone, is a key determinant of targeting performance, highlighting the importance of robust analytical characterization during nanoparticle development. These tools further enable sensitive detection of CAR-expressing cells in both engineered cell populations and whole blood samples. Together, this integrated workflow provides critical solutions for evaluating targeting efficiency, delivery performance, and CAR expression, helping accelerate the development and clinical translation of next-generation in vivo CAR therapies.
