Small-cell lung cancer (SCLC), characterized by its aggressive nature has a poor overall 5-year survival rate (5-10%). The immune evasion program in SCLC is mediated by the low expression levels of molecules needed for T-cell receptor (TCR) recognition, major histocompatibility complex (MHC) class I. Chimeric Antigen Receptor T (CAR T) cells offer a promising strategy for SCLC, with the ability to target cancer cells in a TCR-independent manner. However, access to clinical-grade viral vectors to manufacture CAR T cells remains challenging.
In this webinar, Vimal Keerthi, will discuss his work on identifying CD276 (B7-H3) overexpression in primary human SCLC and developing a non-viral CRISPR- Cas9 knock-in (CKI) based platform against B7-H3 to manufacture CAR T cells for the treatment of SCLC. He will demonstrate the feasibility of this non-viral CAR T manufacturing platform, and how this provides a blueprint for immediate clinical translation overcoming the bottleneck of viral vector production.
Key learning objectives will include:
- Learn more about homology directed repair (HDR) based CRISPR knock-in strategies to engineer T cells.
- Explore how CRISPR/Cas9-engineered CAR T cells can target low-antigen SCLC.
- Learn about the method and feasibility of scaling up clinical-grade production of non-viral CAR T cells for immediate clinical translation.
