All six patients tolerated a single infusion of TruUCAR GC027. No neurotoxicity events (ICANS) or acute graft-versus-host disease (aGvHD) were observed. Cytokine release syndrome (CRS) occurred in all patients and was managed with standard of care including Tocilizumab. Overall safety findings were consistent with previous observations.
"These data show promising long-term follow-up results in r/r T-ALL patients who have very limited treatment options available," commented Dr.

TruUCAR-enabled GC027 is a first-in-human, off-the-shelf allogeneic CAR-T therapy targeting CD7, currently being developed for the treatment of T-ALL in adults. GC027 is manufactured from T cells of human leukocyte antigen (HLA) unmatched healthy donors. Developed on our proprietary TruUCAR platform, GC027 utilizes dual-function CAR to specifically target a patient's own T cells and natural killer (NK) cells that would otherwise be directed against the foreign, or allogeneic, CAR-T cells resulting in rejection by the patients. This novel design allows this allogeneic cell therapy to survive a patient's immune system without the need for combination treatment with additional potent immunosuppressant and represents a differentiated monotherapy approach.
T cell malignancies are a group of cancers involving T lymphocytes, including acute T cell lymphoblastic leukemia or T-ALL. Standard of care treatment for T-ALL includes chemotherapy, radiation therapy and stem cell transplantation. Standard chemotherapy regimens only result in 30% - 40% response rate with 6 months median Overall Survival among responders. Patients with T cell malignancies usually have high relapse and mortality rates. Relapsed patients have dismal prognosis with very limited treatment options and <10% of patients surviving beyond 5 years. Due to shared common surface antigens and potential contamination by malignant cells, development of CAR-T cell therapies for T-ALL is lagged behind. In addition, no new therapies have been approved for the treatment of T-ALL since the approval of Nelarabine (marketed by GlaxoSmithKline) by the FDA in 2005. Globally, approximately 64,000 patients are diagnosed with ALL every year with over approximately 6,000 expected to be diagnosed in
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 vs host disease (GvHD) without the need of being co-administered with immunosuppressive drugs.
The lead program of TruUCAR platform, GC027, is manufactured using T cells from non-HLA matched healthy donors. The TruUCAR platform utilizes novel designs of a dual-function CAR or dual-CAR to reduce HvG, eliminating the need of combination therapy with additional potent immunosuppressant to induce deeper immune suppression and enabling stand-alone allogeneic CAR-T cell therapy.
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, 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 production quality, high therapy cost and lack of effective CAR-T therapies for solid tumors.
