satricabtagene autoleucel (CT041)

However, GI toxicities are reported from clinical use of both Zolbetuximab and CT041...We also demonstrate and characterize on-target/off-tumor gastric toxicity targeting CLDN18.2 in a preclinical mouse model of CT041-scFv derived CAR T cell therapy. By developing CLDN18.2 fully-human VH-only single domain CARs, we demonstrate that on-target/off-tumor toxicity inversely correlates with affinity of the binder, and that a lower affinity CAR may widen the therapeutic window for CLDN18.2 by decreasing on-target/off-tumor toxicity while preserving efficacy.

In patients with resectable and borderline resectable pancreatic cancer, both neoadjuvant/perioperative mFOLFIRINOX and gemcitabine-nab-paclitaxel (GEM-Abraxane) have shown comparable median overall survival (~23-25 months) and R0 resection rates (~64-80%) in the SWOG S1505 trial...The efficacy of novel agents targeting specific molecular pathways, including CLDN18.2 and PDGFRα, is currently being evaluated in early-phase trials (e.g., CT041, IMAB362)...While pancreatic cancer remains a formidable adversary, recent advancements in therapeutic strategies offer hope for improving patient outcomes by leveraging cutting-edge technologies and fostering collaborative research endeavors. This literature review focuses on the latest clinical trial results of novel therapies that have emerged for the management of pancreatic cancer.

This is the first randomised controlled trial of CAR T-cell therapy in solid tumours globally. Satri-cel treatment resulted in a significant improvement in progression-free survival, with a manageable safety profile. These results support satri-cel as a new third-line treatment for advanced gastric or gastro-oesophageal junction cancer patients.

We found that high expression of CLDN18 in ascites epithelial cells correlated with a favorable prognosis, whereas ascites epithelial cells with high MYC expression and strong interactions between tumor cells and T cells were adverse prognostic factors for CT041 treatment. These findings may provide theoretical evidence for the screening of populations that can benefit from CAR T therapy and improve the efficacy of CAR T therapy.

At the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting, the final results of the phase 3 SPOTLIGHT trial were presented, demonstrating a significant survival benefit from the addition of the CLDN18.2-specific antibody zolbetuximab to chemotherapy in the first-line treatment of advanced gastroesophageal adenocarcinomas with ≥ 75% CLDN18.2 expression...In addition, several early-phase trials presented at ASCO 2024 investigate other CLDN18.2-targeting approaches in CLDN18.2-positive refractory advanced solid tumors, including the CLDN18.2-targeting antibody-drug conjugates LM-302 and IBI343, the bispecific anti-CLDN18.2/CD3 antibody IBI38, and the chimeric antigen receptor T cell therapy satricabtagene autoleucel. These novel approaches could potentially expand the benefit of CLDN18.2-targeting therapies to a broader range of tumor types and to tumors expressing lower levels of CLDN18.2.

Satri-cel demonstrates therapeutic potential with a manageable safety profile in patients with CLDN18.2-positive advanced gastrointestinal cancer. ClinicalTrials.gov identifier: NCT03874897 .

In patients with metastatic PC after progression on previous therapy, CT041 demonstrated a tolerable safety profile and encouraging anticancer efficacy signals. Response benefit observed here needs to be ascertained in the future.
