SAN DIEGO, Calif. and SUZHOU and SHANGHAI, China, November 13, 2023 – Gracell Biotechnologies Inc. (NASDAQ: GRCL) (“Gracell” or the “Company”), a global clinical-stage biopharmaceutical company dedicated to developing innovative and highly efficacious cell therapies for the treatment of cancer and autoimmune diseases, today reported third quarter unaudited financial results for the period ended September 30, 2023, and provided corporate updates.


“We are encouraged to see the continued advancement of FasTCAR-T GC012F, our highly differentiated lead candidate. Currently, patient dosing is underway for the company-sponsored Phase 1b/2 trial in the U.S., with more sites to be activated in the near term. It was an honor to present our updated findings from the ongoing IIT trial on NDMM at the 20th International Myeloma Society Annual Meeting as we highlighted the 100% MRD- sCR rate among the 19 NDMM patients treated with GC012F, combined with a highly favorable safety profile. We look forward to presenting an update with more details at ASH 2023,” commented Dr. William (Wei) Cao, founder, Chairman and CEO of Gracell.


“We are highly optimistic about CAR-T's transformative potential in treating autoimmune diseases. GC012F is ideally positioned as a game-changing candidate combining its CD19/BCMA dual-targeting capability, faster and consistent product delivery, and safety track record from 60 patients treated in several IITs. Today, we are delighted to share compelling data from translational research on the IIT patient samples, supporting the strong scientific rational of using GC012F to treat SLE. Our team is diligently focused on advancing the clinical development in rSLE, including furthering the IIT study and submitting the IND filings in the US and China this year. "

About GC012F


GC012F is Gracell’s FasTCAR-enabled BCMA/CD19 dual-targeting autologous CAR-T cell therapy, which aims to transform cancer and autoimmune disease treatment by driving fast, deep and durable responses with improved safety profile. GC012F is currently being evaluated in clinical studies in multiple hematological cancers as well as autoimmune diseases, and has demonstrated a consistently strong efficacy and safety profile. Gracell has initiated a Phase 1b/2 trial evaluating GC012F for the treatment of relapsed/refractory multiple myeloma in the United States and a Phase 1/2 clinical trial in China is to be commenced imminently. Gracell has also launched an IIT evaluating GC012F for the treatment of refractory systemic lupus erythematosus (rSLE).


About FasTCAR


Introduced in 2017, FasTCAR is Gracell’s revolutionary next-day autologous CAR-T cell manufacturing platform. FasTCAR is designed to lead the next generation of therapy for cancer and autoimmune diseases, and improve outcomes for patients by enhancing effect, reducing costs, and enabling more patients to access critical CAR-T treatment. FasTCAR drastically shortens cell production from weeks to overnight, potentially reducing patient wait times and probability for their disease to progress. Furthermore, FasTCAR T-cells appear younger and are more robust than traditional CAR-T cells, making them more proliferative and effective at killing cancer cells. In November 2022, FasTCAR was named the winner of the Biotech Innovation category of the 2022 Fierce Life Sciences Innovation Awards for its ability to address major industry obstacles.







Suppressive Molecule Activated and Rejuvenated T cells (SMART CART™) is Gracell’s proprietary technology module designed to further strengthen the functionality of CAR-T cells and aims to overcome tumor microenvironment (TME). SMART CART™ includes altered expression of the receptor and signaling mechanism of an inhibitory TME molecule, transforming growth factor-β (TGF-β), to enhance expansion and persistence and to reduce the exhaustion of CAR-T cells. This design reverses and turns immunosuppressive signals of TME into stimulatory reactions of CAR-T cells. SMART CART™ technology can be applied to many targets for the treatment of solid tumors.
