SAN DIEGO and SUZHOU, China and SHANGHAI, China, Aug. 14, 2023 (GLOBE NEWSWIRE) -- 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 second quarter unaudited financial results for the period ended June 30, 2023, and provided corporate updates.

“We are delighted with the significant milestones achieved in the past few months across our reprioritized pipeline. Encouraged by the latest impressive clinical data for GC012F across hematological indications presented at ASCO and EHA, we continue to focus on the development and expansion of this highly-competitive, next-generation CAR-T product candidate. The Phase 1b part of the RRMM US IND trial has commenced as patient screening is underway. We also continue to explore the potential of GC012F in early line, and look forward to presenting longer follow-up data from the ongoing clinical IIT evaluating GC012F in newly diagnosed multiple myeloma (NDMM) at an upcoming international medical conference in September,” said Dr. William (Wei) Cao, founder, Chairman and CEO of Gracell. “The expansion into the autoimmune diseases is also a priority and we are on track to file the US IND in 2023 to conduct a Phase 1 trial for GC012F in rSLE. We have dosed multiple patients in the rSLE IIT and anticipate that topline data from this ongoing study will be available during the first half of 2024.”

Dr. Cao continued, “With the completion of a private placement financing of $100 million upfront and up to $50 million upon warrant exercise led by well-regarded healthcare investors, we strengthened our balance sheet and extended our runway into the second half of 2026.”

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. GC102F 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 US and expects to initiate a Phase 1/2 clinical trial in China. Gracell has also commenced an investigator-initiated trial 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 cell therapy for cancer and autoimmune diseases, and improve outcomes for patients by enhancing CAR-T cell fitness, 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 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.

About Gracell
Gracell Biotechnologies Inc. (“Gracell”) is a global clinical-stage biopharmaceutical company dedicated to discovering and developing breakthrough cell therapies for the treatment of cancers and autoimmune diseases. Leveraging its innovative FasTCAR and TruUCAR technology platforms and SMART CAR™ 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 and autoimmune diseases. The lead candidate BCMA/CD19 dual-targeting FasTCAR-T GC012F is currently being evaluated in the clinical studies for the treatment of multiple myeloma, B-NHL and systemic lupus erythematosus (SLE).
