Shanghai Cellular Biopharmaceutical Group presents first data from Phase I trial evaluating a novel CAR-T in advanced liver cancer at AACR Annual Meeting

PRNewswire April 18, 2023

Promising anti-tumor activity reported for C-CAR031, a novel Glypican 3 (GPC3)-targeting cell therapy designed by AstraZeneca

SHANGHAI, April 18, 2023 /PRNewswire/ — Shanghai Cellular Biopharmaceutical Group Ltd. (the Company, or Shanghai Cellular Bio), a company engaged in the drug development of immunotherapies for cancer and stem cell therapies for degenerative diseases, today presented data from the First-in-Human (FIH) Phase I trial evaluating C-CAR031 at the 2023 American Association for Cancer Research (AACR) Annual Meeting.

Early results indicate that C-CAR031 is well tolerated with promising anti-tumor activity seen and objective responses in several patients to date, including 3 patients with confirmed partial responses, 2 with stable disease and 1 with progressive disease per both RECIST v1.1 and mRECIST criteria. The clinical responses of the patients who achieved partial responses are ongoing up to the data cutoff date.

C-CAR031 is an autologous GPC3-directed second generation armored CAR-T with affinity-tuned single-chain variable fragment (scFv) to enhance its  safety profile, based on a novel cell therapy designed by AstraZeneca (LSE/STO/Nasdaq:AZN) using their TGFβRII dominant negative armoring discovery platform.

To investigate the feasibility, safety and initial efficacy of C-CAR301 in hepatocellular carcinoma (HCC), Shanghai Cellular Bio is currently conducting a Phase I FIH clinical study (NCT05155189) in advanced HCC in The First Affiliated Hospital, Zhejiang University School of Medicine in Hangzhou, China.

Methods: This FIH, open-label dose escalation trial employs an accelerated dose titration plus i3+3 design. Histologically confirmed GPC3+ advanced HCC patients (pts) who failed systemic treatments received a single-dose i.v. infusion of C-CAR031 following standard lymphodepletion. The primary objective was to assess the safety and tolerability. Adverse events (AEs) were graded using CTCAE 5.0, and cytokine release syndrome (CRS) / immune effector cell-associated neurotoxicity syndrome (ICANS) were graded according to ASTCT 2019 criteria.

Results: As of March 2nd, 2023, seven patients received two dose levels (DL1, n=1; DL2, n=6) of C-CAR031. The median number of prior lines of therapies was 4 (range 1-6). The median follow-up was 77 (67-213) days. Seven patients with ≥28 days’ follow-up were eligible for safety evaluation. Good safety profile was observed at explored dose levels.  86% (6/7) patients experienced Gr1/2 CRS; no Dose Limiting Toxicities (DLT) or ICANS was observed. The ≥Gr3 non-hematologic product-related AE included transient Gr3 AST elevation (2/7, 28%), hypokalemia (1/7, 14%), and abdominal pain (1/7,14%). 5/6 (83%) patients at DL2 showed tumor shrinkage post C-CAR031 treatment (median -41.4% range -3.4%~ – 94.4%).  Best clinical responses at DL2 included 3 confirmed PR, 2 SD and 1 PD per both RECIST v1.1 and mRECIST. The clinical responses of the patients who achieved PR are ongoing up to the cutoff date. C-CAR031 showed a robust cellular kinetic profile. CAR-T cells were detectable in blood of all patients in the last follow-up.

Conclusion: In this FIH study, C-CAR031 is well tolerated and shows promising anti-tumor activity. Enrollment is ongoing to confirm initial results.
