SAN DIEGO, Calif. and SUZHOU and SHANGHAI, China, May 16, 2022 (GLOBE NEWSWIRE) -- 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 first quarter unaudited financial results for the three months ended March 31, 2022, and provided corporate updates.

“We were very encouraged about our early results from a first-in-human IIT study of our allogeneic TruUCAR candidate GC502 in patients with relapsed/refractory B-ALL, which we presented at AACR in early April. After a single infusion of the CD19/CD7 dual-directed off-the-shelf allogeneic CAR-T therapy GC502, three out of four patients achieved MRD- CR/CRi, and patients continue to be followed for ongoing response assessment,” said Dr. William (Wei) Cao, founder, Chairman, and CEO of Gracell. “We are dedicated to advancing our rich clinical pipeline with multiple IIT proof-of-concept trials as well as two IND-approved studies underway. We look forward to the upcoming oral and poster presentations at ASCO 2022 and EHA 2022, highlighting the clinical data for our BCMA/CD19 dual-targeting CAR-T candidate GC012F in two indications of RRMM and B-NHL, and allogeneic CAR-T candidate GC502 in B-ALL.”

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 RRMM and B-NHL.

• Updated clinical data from an IIT evaluating GC012F for the treatment of RRMM selected for oral abstract presentation on June 5 at 2022 American Society of Clinical Oncology Annual Meeting (ASCO 2022) and on June 12 at European Hematology Association 2022 Congress (EHA 2022).
• Plan to present Initial data from an ongoing IIT evaluating GC012F for the treatment of r/r B-NHL as a poster presentation on June 10 at EHA 2022.
• Plan to submit the U.S. and China IND filings for RRMM 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 (human leukocyte antigen) matched healthy donors.

• First-in-human data from China IIT study in B-ALL patients were presented at AACR on April 12, 2022. As of the January 28, 2022 data cutoff date, four patients enrolled had received a single dose of GC502, including one patient at dose level 1 (DL1) 1.0x10⁷ cells/kg and three patients at dose level 2 (DL2) 1.5x10⁷ cells/kg. Three out of four patients achieved minimal residual disease negative complete response or complete response with incomplete count recovery (MRD- CR/CRi), and one patient achieved a partial response at month one and subsequently received allogeneic hematopoietic stem-cell transplantation (allo-HSCT) on day 39. In two different formulation groups, safety profile appeared to be manageable and feasible.
• Plan to present updated data with longer follow-up of GC502 in B-ALL on June 10 at EHA 2022.

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

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

SMART CART^TM Technology: With unique construct to take advantage of the suppressive tumor microenvironment (TME) and effectively combat solid tumors, SMART CART^TM 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 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.

• Registrational Phase 1/2 clinical trial under a China IND is ongoing for the treatment of r/r B-ALL. Enrolling patients in the second dosing cohort prior to entering the Phase 2 part of the seamless-design study.
  

Corporate Highlights

• Opened the Company’s R&D Center in San Diego, Calif., during the first quarter of 2022.
  

Financial Results for the First Quarter Ended March 31, 2022

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, and, together with fast turnaround time, it enables enhanced accessibility of cell therapies for cancer patients.

About TruUCAR
TruUCAR is Gracell’s proprietary technology platform and is designed to generate CAR-T cell therapies from high quality allogeneic T cells that can be administered “off-the-shelf” at lower cost and with improved accessibility of cell therapies for cancer patients. 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 strong immunosuppressant after conventional lymphodepletion. The novel dual-CAR design allows tumor antigen-CAR moiety to target malignant cells, while the CD7 CAR moiety is designed to suppress rejection of allogeneic CAR-T cells by host T and NK cells (HvG).

About SMART CART^TM
SMART CART^TM is Gracell’s proprietary technology module designed to strengthen the functionality of CAR-T cells further, and aims to overcome tumor microenvironment (TME). SMART CART^TM 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 CART^TM 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 CART^TM 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.
