Management to host conference call at 8:00 a.m. ET today

SAN DIEGO, Calif. and SUZHOU and SHANGHAI, China, August 15, 2022 – Gracell Biotechnologies Inc. (NASDAQ: GRCL) (“Gracell” or “Company”), a global clinical-stage biopharmaceutical company dedicated to discovering and developing highly efficacious and affordable cell therapies for the treatment of cancer, today reported second quarter unaudited financial results for the period ended June 30, 2022, and provided corporate updates.

“In recent months, we have made significant clinical progress for our lead candidate, the BCMA/CD19 dual-targeting FasTCAR GC012F. The updated clinical data from the fully enrolled r/r MM study showcased the deep response achieved, favorable safety profile and the differentiated next-day manufacturing at both ASCO and EHA. We are encouraged by the consistently positive data and are on track to complete the IND submissions for GC012F in r/r MM in both the U.S. and China before year end,” said Dr. William (Wei) Cao, founder, Chairman, and CEO of Gracell. “We have also reported at EHA the first-in-human data for GC012F in r/r B-NHL and the updated data for the allogeneic GC502 in r/r B-ALL. Our frontline NDMM study of GC012F is actively enrolling patients. I am very pleased with the depth of our differentiated CAR-T pipeline and looking forward to reporting clinical data from a few ongoing clinical studies at major medical meeting later this year. We strengthened our leadership team in recent weeks and the entire Gracell team is committed to achieving our vision of making CAR-T therapy more effective, safer and more broadly accessible to patients.”

Pipeline Highlights     

FasTCAR Platform: Next-day manufacturing for autologous CAR-T cell therapy

GC012F: Autologous CAR-T therapeutic candidate dual-targeting B cell maturation antigen (BCMA) and CD19, currently being evaluated for the treatment of r/r MM, NDMM and r/r B-NHL.



Dataset from an investigator-initiated trial (IIT) evaluating GC012F for the treatment of r/r MM presented as oral presentations at American Society of Clinical Oncology Annual Meeting (ASCO 2022) and European Hematology Association 2022 Congress (EHA 2022)



Underscored the deep responses achieved, including a 100% MRD negativity rate in all patients treated, as of the June 8, 2022 cutoff date following enrollment completion with 29 patients, of which 90% were classified as high risk



Demonstrated consistently favorable safety profile and promising mDOR of 15.7 months in mostly high risk and heavily pretreated patients



Enrollment progressing in an IIT in China evaluating GC012F in NDMM



Presented initial data from an ongoing IIT evaluating GC012F for the treatment of r/r B-NHL at EHA 2022



Demonstrated potent and fast activity with 100% CR rate at one-month observed in all three patients with r/r B-NHL (3/3 DLBCL) including patients with bulky disease, as of the February 22, 2022 cutoff date



On track to submit the U.S. and China IND filings for r/r MM in the second half of 2022

TruUCAR Platform: Novel designs enabling “off-the-shelf” allogeneic CAR-T therapy

GC502: TruUCAR-enabled CD19/CD7 dual-directed allogeneic CAR-T cell therapy being studied in an ongoing Phase 1 IIT in China for the treatment of B-cell malignancies. GC502 is manufactured from T cells of non-HLA (non-human leukocyte antigen) matched healthy donors.



Updated data from single-arm, open-label IIT with longer follow-up of GC502 in r/r B-ALL presented at EHA 2022.



As of the February 22, 2022 cutoff date, data from four patients across two formulations demonstrated very promising response rates at their one-month assessments, manageable and reversible adverse events, and robust expansion of GC502

GC027: TruUCAR-enabled CD7-targeted allogenic CAR-T cell therapy for the treatment of relapsed/refractory T cell acute lymphoblastic leukemia (r/r T-ALL).



Target to have regulatory interactions globally and in China in the next 12 months.

SMART CARTTM Platform: With unique construct to take advantage of the suppressive tumor microenvironment (TME) and effectively combat solid tumors, SMART CARTTM is designed to enhance CAR-T cell proliferation and duration of killing, and to resist exhaustion with improved persistence of CAR-T cells.



On track to commence patient enrollment in a China IIT for GC503 in mesothelin-positive solid tumors in 2022.



Plan to commence a China IIT for GC506 in CLDN18.2-positive solid tumors.

GC007g for the treatment of r/r B-ALL: GC007g is an allogeneic CD19-targeted CAR-T cell therapy, derived from HLA-matched donor, for the treatment of r/r B-ALL patients who failed transplant and may not be eligible for autologous CAR-T therapy.



Completed the Phase 1 portion of the registrational Phase 1/2 clinical trial underway under a China IND for the treatment of r/r B-ALL. On track to commence Phase 2 portion in the third quarter 2022.

Research and Development Expenses

Research and development expenses for the three months ended June 30, 2022 were RMB117.1 million (US$17.5 million), compared to RMB65.3 million in the corresponding prior year period. The increase was primarily due to the increased spending on research, development, and clinical trials, as well as higher payroll and personnel expenses attributable to increased headcount, and higher facility-related costs.

Administrative Expenses

Administrative expenses for the three months ended June 30, 2022 were RMB28.8 million (US$4.3 million), compared to RMB30.4 million for the corresponding prior year period. The decrease was primarily driven by a decrease in professional service and a decrease in share-based compensation expenses.

About FasTCAR

CAR-T cells manufactured on Gracell’s proprietary FasTCAR platform appear younger, less exhausted, and show enhanced proliferation, persistence, bone marrow migration, and tumor cell clearance activities as demonstrated in preclinical studies. With next-day manufacturing, FasTCAR is able to significantly improve cell production efficiency, which may result in meaningful cost savings, increasing the accessibility of cell therapies for cancer patients.

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 of unique genes, TruUCAR is designed to control host vs graft rejection (HvG) as well as graft vs host disease (GvHD) without the need of being co-administered with additional immunosuppressive drugs.


SMART CARTTM is Gracell’s proprietary technology module designed to strengthen the functionality of CAR-T cells further, and aims to overcome tumor microenvironment (TME). SMART CARTTM includes altered expression of the receptor and signaling mechanism of an inhibitory TME molecule 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 CARTTM technology can be applied to many targets for the treatment of solid tumors.

About Gracell

Gracell Biotechnologies Inc. (“Gracell”) is a global clinical-stage biopharmaceutical company dedicated to discovering and developing breakthrough cell therapies. Leveraging its pioneering FasTCAR and TruUCAR technology platforms and SMART CARTTM technology module, Gracell is developing a rich clinical-stage pipeline of multiple autologous and allogeneic product candidates with the potential to overcome major industry challenges that persist with conventional CAR-T therapies, including lengthy manufacturing time, suboptimal cell quality, high therapy cost and lack of effective CAR-T therapies for solid tumors.
