KRAS G12D-specific Immune Effector Cells Targeting KRAS G12D-positive Solid Tumors

3. november 2026 oppdatert av: Shenzhen Geno-Immune Medical Institute

KRAS G12D-specific Engineered Immune Effectors (EIE) Targeting High-risk Tumors With KRAS G12D Mutation

The purpose of this study is to assess the feasibility, safety and efficacy of KRAS G12D-specific engineered immune effector (EIE) therapy in patients with advanced, KRAS G12D-positive malignancies. Another goal of the study is to characterize the function, expansion and persistence of KRAS G12D-specific effector cells in treated patients.

Important Regulatory Notice:

This trial record is only for global academic information registration on ClinicalTrials.gov. Neither the sponsor Beijing Meikang Jimian Biotechnology Co., Ltd. nor collaborator Shenzhen Geno-Immune Medical Institute has obtained NMPA clinical trial approval or clinical technology filing permission to carry out interventional cell therapy trials in mainland China.

ClinicalTrials.gov registration alone does not represent legal approval by Chinese health and drug regulatory authorities.

KRAS G12D mutation is one of the most frequent oncogenic drivers in human malignancies including pancreatic ductal adenocarcinoma, colorectal cancer, non-small cell lung cancer and other advanced solid tumors. Patients with metastatic KRAS G12D mutated tumors generally have poor prognosis; after failure of standard chemotherapy, targeted therapy and checkpoint immunotherapy, effective salvage treatment options remain very limited, and overall survival is unsatisfactory. Conventional chemotherapy and existing targeted agents cannot achieve durable tumor control for large proportions of these patients.

The somatic KRAS G12D neoantigen is tumor-specific, absent in normal human tissues, and critical for maintaining malignant phenotypes, which makes it an attractive target for adoptive cell immunotherapy. This trial investigates autologous KRAS G12D-specific EIE therapy. Peripheral blood mononuclear cells (PBMCs) will be collected via leukapheresis and stimulated with autologous dendritic cells primed with KRAS G12D-specific immunogenic peptides. Manufactured EIE products will be phenotypically profiled for CD8+, CD4+ and CD56+ lymphocyte subsets together with antigen specific reactivity. This phase 1/2 study aims to evaluate safety, manufacturing feasibility and preliminary anti-tumor efficacy of autologous KRAS G12D-specific EIEs in subjects with KRAS G12D-positive tumors.

Objective response (complete response (CR) + partial response (PR)) will be assessed by the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria. CR is disappearance of all target lesions. Any pathological lesions (whether target or non-target) must have reduction in short axis to <10 mm. Partial response is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.
