Engineered immune cells take on Hard-to-Treat cancers in early trial
NCT ID NCT06767046
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage trial tests a personalized cell therapy for people with advanced colorectal, pancreatic, or lung cancers that have a specific KRAS G12V mutation. The treatment involves taking a patient's own immune T cells, engineering them to recognize and attack cancer cells, and infusing them back. The study aims to check safety and see if the therapy can shrink tumors in just 8 participants who have run out of standard options.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- KRAS-specific autologous TCR-T cells (CRTKVA11-N04) plus fludarabine, cyclophosphamide, and interleukin-2
- What this could lead to
- If successful, this could point toward a new treatment option for advanced solid tumors with the KRAS G12V mutation, potentially shrinking tumors or slowing disease progression.
- What could go wrong
- This is a very early (Phase 1) and small (8 participants) study focused mainly on safety. The treatment may not shrink tumors, and side effects could be serious, including immune reactions or organ damage.

Inclusion Criteria: * Patients aged 18-70 years. * Histologically or cytologically confirmed advanced solid tumors (e.g., colorectal cancer, pancreatic cancer, NSCLC) with KRAS G12V mutations and HLA-A\*11:01 genotype. * Failed standard therapies or no effective treatment available. * ECOG performance status of 0-1. * Life expectancy of ≥3 months. * Presence of at least one measurable lesion as defined by RECIST 1.1 criteria. * Female patients of childbearing potential must agree to use highly effective contraceptive methods during the study and for at least 6 months after the last dose. A negative pregnancy test within 7 days prior to treatment initiation is required. * Written informed consent provided by the patient, with an expectation of compliance with study procedures. Exclusion Criteria: * 1.Prior treatment with gene-modified T-cell therapies. * Current treatment with T-cell suppressive agents (e.g., cyclophosphamide, FK506, tripterygium glycosides) or T-cell stimulants. * Chemotherapy, targeted therapy, immunotherapy, or investigational drugs administered within 2 weeks, or radiotherapy within 4 weeks prior to enrollment. * Significant organ dysfunction, as evidenced by: * leukocytes\<3.0 x 109/L * absolute neutrophil count \>1.5 x 109/L * hemoglobin\<90g/L * platelets \<100 x 109/L * Creatinine\>1.5×ULN or creatinine clearance \<50mL/min * lymphocytes\<0.5 x 109/L * total bilirubin\>3×ULN; ALT/AST\>3×ULN (or \>5× ULN in patients with liver metastases) * INR/APTT\>1.5×ULN; * SpO2≤93% * Presence of serious diseases and comorbidities, including but not limited to: severe heart disease, cerebrovascular disease, seizures, poorly controlled diabetes (such as Type 1 diabetes or insulin-dependent diabetes), pancreatic dysfunction, severe infections, active gastrointestinal ulcers, gastrointestinal bleeding, mechanical or paralytic bowel obstruction, pulmonary fibrosis, renal failure, respiratory failure, etc. * History of severe cardiovascular diseases within the past 6 months, including but not limited to: myocardial infarction, severe or unstable angina, coronary artery or peripheral artery bypass surgery, New York Heart Association (NYHA) Class III or IV heart failure, etc. * Left ventricular ejection fraction (LVEF) \< 50%. * Symptomatic brain metastases unless stabilized with prior treatment (e.g., surgery or radiotherapy). * Known history of myelodysplastic syndrome, lymphoma, or other malignancies. * Known allergy to albumin, investigational drugs, or their excipients. * Active autoimmune diseases, including but not limited to acquired/congenital immunodeficiency, organ transplantation, autoimmune hepatitis, systemic lupus erythematosus, or inflammatory bowel disease. * Active hepatitis B, hepatitis C, or HIV infection. * Pregnancy or breastfeeding. * Uncontrolled mental or neurological disorders. * Any condition deemed unsuitable for study participation by the investigator.
