Gracell Biotechnologies to Present Preclinical Results of TruUCAR-enabled CD19/CD7 Dual-Directed Allogeneic CAR-T Cell Therapy (GC502) for B-Cell Malignancies at the 63rd ASH Annual Meeting
Gracell Biotechnologies (NASDAQ: GRCL) announced preclinical data for GC502, an allogeneic CAR-T cell therapy targeting B-cell malignancies. This data will be presented at the 63rd American Society of Hematology Annual Meeting on December 11, 2021. GC502 utilizes Gracell's TruUCAR technology, showing strong anti-tumor efficacy and potential to suppress host versus graft rejection without the need for additional immunosuppressive drugs. The company is optimistic about further clinical development for this therapy aimed at improving treatment options for patients with B-cell malignancies.
- GC502 demonstrates robust anti-tumor efficacy in preclinical studies.
- Potential to suppress host versus graft rejection without additional immunosuppressive therapy.
- Utilizes proprietary TruUCAR technology, allowing for off-the-shelf CAR-T therapies.
- None.
SUZHOU and SHANGHAI, China, and PALO ALTO, California, Nov. 4, 2021 /PRNewswire/ -- Gracell Biotechnologies Inc. (NASDAQ: GRCL) ("Gracell"), a global clinical-stage biopharmaceutical company dedicated to developing highly efficacious and affordable cell therapies for the treatment of cancer, today announced preclinical data for GC502, an allogeneic chimeric antigen receptor (CAR) T cell therapy for the treatment of B-cell malignancies, will be presented as a virtual poster at the 63rd American Society of Hematology (ASH) Annual Meeting and Exposition as part of the "Cellular Immunotherapies: Basic and Translational" session on December 11, 2021 from 5:30 p.m.-7:30 p.m.(EST).
GC502 is a CD19/CD7 dual-directed, stand-alone off-the-shelf allogeneic CAR-T therapy for the treatment of B-cell malignancies developed on Gracell's proprietary TruUCAR technology platform. The novel dual CAR design allows the CD19 CAR moiety to target malignant cells, while the CD7 CAR moiety is designed to suppress host versus graft (HvG) (rejection) response, enabling GC502 to be a stand-alone therapy. Preclinical results demonstrate robust anti-tumor efficacy and promising potential to suppress HvG disease without the need for additional immunosuppressive therapeutics.
TruUCAR is Gracell's proprietary technology platform designed to generate high-quality allogeneic CAR-T therapies using T cells from non-HLA matched healthy donors, manufactured in large quantities as "off-the-shelf" products at a lower cost.
"Encouraging preclinical data with GC502 validates the functionality of dual CAR developed on our TruUCAR platform and highlights the potential of our proprietary off-the-shelf, stand-alone allogeneic therapies for a broad range of patients." Said Dr. Xinxin Wang, Vice President, Research and Development at Gracell.
"GC502 displays strong anti-tumor potency and suppression of HvG response in the preclinical study. We look forward to further clinical development of GC502 and expanding our early-stage pipeline with more safe, effective and accessible cell therapies for tough to treat hematological malignancies." Commented Dr. Lianjun Shen, Senior Vice President, Head of Research and Development at Gracell.

About GC502
GC502 is a TruUCAR-enabled CD19/CD7 dual-directed, off-the-shelf allogeneic CAR-T product candidate that is being studied for the treatment of B-cell malignancies, including B-ALL and B-NHL. GC502 is manufactured using T cells from non-HLA matched healthy donors. An enhancer molecule is embedded in the basic construct of TruUCAR to enhance proliferation of TruUCAR T cells. Optimized for CD19/CD7 dual CAR functionality and in vivo durability, GC502 has demonstrated robust anti-tumor efficacy with promising potential to suppress host vs graft (HvG) rejection in preclinical models.
About B-ALL and B-NHL
Acute lymphoblastic leukemia (ALL) is a type of blood cancer characterized by proliferation of immature lymphocytes in the bone marrow, which can involve either T lymphocytes (T-ALL), or B lymphocytes (B-ALL). Globally, approximately 64,000 patients are diagnosed with ALL every year with approximately 6,000 diagnosed in the United States, and approximately 7,400 diagnosed in China in 2020[1]. B-ALL accounts for
Non-Hodgkin's lymphoma (NHL) is a group of blood cancers that developed from lymphocytes, most commonly derived from B cells (B-NHL). Globally, approximately 510,000 patients are diagnosed with NHL every year with over 77,000 patients diagnosed in the United States, and approximately 68,000 diagnosed in China in 2020[2]. B-NHL accounts for approximately
About TruUCAR
TruUCAR is Gracell's proprietary technology platform and is designed to generate high-quality allogeneic CAR-T cell therapies that can be administered "off-the-shelf" at lower cost and with greater convenience. With differentiated design enabled by gene editing, TruUCAR is designed to control host vs graft rejection (HvG) as well as graft versus host disease (GvHD) without the need for being co-administered with immunosuppressive drugs. The novel dual CAR design allows tumor antigen-CAR moiety to target malignant cells, while the CD7 CAR moiety is designed to suppress host versus graft (HvG) response, enabling TruUCAR T cell to be a stand-alone therapy.
