Study Overview

A Clinical Trial Targeting CEA Chimeric Antigen Receptor T (CAR-T) for CEA Positive Advanced Malignant Solid Tumors

This is a single-arm, open, dose-increasing phase I clinical study to explore the safety, tolerability and pharmacokinetic characteristics of the drug C-13-60 cells, and preliminarily observe the efficacy of the drug in CEA positive late malignant solid tumors, and explore the applicable dose regimen for phase II clinical trials.

According to the sequence principle of low and high dose of C-13-60 cell reinfusion, the dose escalation experiment was carried out successively. Three subjects in each dose group were enrolled first. If DLT did not appear, the decision of whether to enter the next dose group was made according to Safety review committee (SRC) resolution. If there was one case of DLT, then 3 subjects were enrolled one by one, and DLT observation was completed for 28 days after each subject's infusion. If no DLT was found, the next infusion was continued. If DLT was found, the subsequent enrollment of the dose group was terminated, and the experiment was terminated or the dose was reduced according to the dose increasing principle. If > 1 case of DLT occurs, the trial is terminated or the dose is reduced.According to the evaluation of the researchers, the subjects who met the conditions of antisepsis received antisepsis chemotherapy 1-5 to -3 days before the transfusion of C-13-60 cells；

Patients with advanced malignant solid tumors confirmed by histology or pathology, including colorectal cancer, esophageal cancer, gastric cancer, pancreatic cancer, non-small cell lung cancer, breast cancer, and cholangiocarcinoma; 3. Progression or intolerance occurs after receiving systematic standard therapy according to guidelines,(systemic therapy including but not limited to systemic chemotherapy, molecular targeting, etc.) and is not suitable for surgery or local therapy (including ablative therapy, interventional therapy, and radiation therapy), among which colorectal cancer needs to receive at least third-line therapy failure or intolerance or inapplicability. Esophageal, gastric, non-small cell lung, breast, and cholangiocarcinoma require at least second-line treatment failure or intolerance or inadequacy, and pancreatic cancer require at least first-line treatment failure or intolerance or inadequacy:
    1. Advanced colorectal cancer: progression or intolerance or inadequacy after third-line standard therapy including cetuximab ± Irinotecan/regorafenib /fruquintinib/trifluridine； 2. Advanced or metastatic esophageal cancer/esophagogastric junction cancer: patients with esophageal cancer who progress or are intolerant or inapplicable after second-line therapy including PD-1 MAB /PD-L1 mab; Patients with esophagogastric junction cancer progressed or were intolerant or inapplicable after second-line therapy including taxane or irinotecan or PD-1 /PD-L1 monoclonal antibody; For HER-2 positive patients, trastuzumab containing system therapy should fail or be intolerable or not applicable; 3.

Patients with advanced, metastatic, or recurrent non-small cell lung cancer who have received systemic treatment progression or intolerance, including: Patients with positive driver genes (EGFR, ALK, ROS1, BRAF, NTRK, MET, RET) should receive targeted therapy failure or drug resistance (squamous cell carcinoma does not require driver gene testing). In addition, patients with EGFR-positive driver gene who are resistant to first-line EGFR-Tkis and who are positive for EGFR T790M mutations need to be treated with third-generation EGFR-TKI (such as Osimertinib, almonertinib, or furmonertinib) after failure or resistance.
