Gracell Announces Presentation at the Annual Meeting of American Society of Clinical Oncology (ASCO)
SUZHOU and SHANGHAI, China, May. 29, 2020 — Gracell Biotechnologies Co., Ltd. ("Gracell"), a clinical-stage immune cell and gene therapy company, today announced that one presentation was accepted at the 2020 American Society of Clinical Oncology (ASCO) Virtual Scientific Program. 

The presentation can be found in the Development Therapeutics – Immunotherapy session, central on Gracell’s EnhancedCAR GC008t in patients with advanced mesothelin-positive solid tumors. 

“We are delighted to report on EnhancedCAR GC008t in solid tumors” said Dr. Martina Sersch, CMO of Gracell. “and glad to share safety and preliminary efficacy data on two of our exciting new CAR-T platform therapies with the scientific community at the ASCO annual meeting.” Dr. William CAO, CEO of Gracell, added “Thanks to our highly efficient gene editing capability, CAR-T cells with PD-1 gene edited are generated to have enhanced capability of tumor control in inhibitory tumor microenvironment. We believe this strategy will improve CAR-T/TCR-T’s potency against solid tumors.  Gracell carried out this strategy as early as 2017, upon our foundation. With two years’ preclinical and clinical investigations, we are very glad to see it showing first encouraging results in an effort to enhance CAR-T cells to combat solid tumors”. 

Session type: poster
Abstract Title: Phase I study of CRISPR-engineered CAR-T cells with PD-1 inactivation in treating mesothelin-positive solid tumors
Abstract ID: 3038

About EnhancedCAR
EnhancedCAR is Gracell’s proprietary and patented platform technology, with selected genes edited to enhance immune cell performance in terms of killing efficiency, in vivo persistence, including selected PD-1 and TCR mediations. The technology can be implemented to many other targets with high editing precision and efficiency. 

About GC008t
GC008t is an investigational, autologous CAR-T cell therapy, redirected to mesothelin with PD-1 disruption for the treatment of mesothelin-positive solid tumors. With PD-1 knocking out, GC008t is expected improve persistence and clinical efficacy. 

About Mesothelin-positive Solid Tumors 
Mesothelin, a cell surface antigen, has high expression to a broad spectrum of solid tumors while express low levels on normal cells. Mesothelin is believed as a good target for multiple solid tumors. The GC008t study enrolled patients with advanced solid tumors, including pancreatic cancer, ovarian cancer, and colorectal cancer, of which clinical outcome of standard of care remains poor.

About Gracell
Gracell Biotechnologies Co., Ltd. ("Gracell") is a clinical-stage biotech company, committed to developing highly reliable and affordable cell gene therapies for cancer. Gracell is dedicated to resolving the remaining challenges in CAR-T, such as high production costs, lengthy manufacturing process, lack of off-the-shelf products, and inefficacy against solid tumors. Led by a group of world-class scientists, Gracell is advancing FasTCAR™, TruUCAR™ (off-the-shelf CAR), DualCAR and EnhancedCAR-T cell therapies for leukemia, lymphoma, myeloma, and solid tumors.
