IX001 TCR-T In the Treatment of Advanced Pancreatic Cancer and Colorectal Cancer Induced by KRAS Mutations

Recruiting now · Phase 1

Conditions studied: Pancreatic Cancer, Colorectal Cancer

In brief

This is a single-arm, single-center, open-label clinical study aimed at evaluating the safety and efficacy of IX001 TCR-T (T cell receptor-engineered T-Cell) injection in patients with advanced pancreatic cancer and colorectal cancer induced by KRAS (Kirsten Rat Sarcoma Viral Oncogene) mutations. A total of 6-18 evaluable patients are planned to be enrolled. The study will include 4 dose groups, using a '3+3' dose escalation design.

Who can join

Age: 18 and older, up to 70. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Voluntary signing of an informed consent form (ICF);
• Males or females, aged 18-70 years (inclusive);
• Pathologically diagnosed with advanced pancreatic cancer or colorectal cancer, having failed or intolerant to at least two lines of standard of care, including metastatic tumors (having received conventional chemotherapy), recurrent tumors (having undergone surgery and adjuvant chemotherapy in the past), or locally advanced tumors with disease progression after neoadjuvant treatment;
• At least one measurable lesion (according to RECIST1.1[The Response Evaluation Criteria In Solid Tumors] criteria);
• Patients with tumor tissue or peripheral blood testing positive for KRAS-G12V or G12D mutations and expression of matching HLA-A*11, C*01:02, or C*08:02 subtypes;
• ECOG (Eastern Cooperative Oncology Group)≤2;
• Life expectancy ≥3 months;
• Absolute neutrophil count ≥1×10E9/L;
• Platelet count ≥50×10E9/L, hemoglobin>90g/dL;
• Absolute lymphocyte count ≥0.5×10E9/L;
• Adequate functional reserve of organs:
• Aspartate aminotransferase ≤2.5×ULN (upper limit of normal);
• Aspartate transaminase ≤2.5×ULN;
• Creatinine clearance ≥60mL/min;
• Total serum bilirubin ≤1.5×UNL;
• The subject has left ventricular ejection fraction (LVEF) ≥ 50% and no clinically significant pericardial effusion diagnosed by echocardiography;
• No clinically significant electrocardiographic abnormality;
• Basic oxygen saturation is >92% under the indoor natural air environment.
• Women of childbearing age must be negative for blood HCG (Human Chorionic Gonadotropin) pregnancy test (by immunofluorescence method) at screening and baseline periods, and agree to use effective contraception for at least 1 year after infusion; and male subjects whose partners are women of childbearing age must agree to use effective barrier contraception methods and avoid sperm donation for at least 1 year after infusion. Contraception must include one highly effective and one additional effective (barrier) method, initiated from screening until at least 1 year after IX001 infusion or until two consecutive flow cytometry tests show the absence of TCR-T cells (whichever occurs later).

You may not qualify if…

• Other malignancies (except non-melanoma skin cancer with the disease-free survival of more than 5 years and cervical carcinoma in situ, bladder cancer, or breast cancer);
• A history of mental disorders, which may affect compliance with this protocol or lead to failure in signing the ICF;
• Poorly controlled hypertension with drug (systolic blood pressure >160 mmHg and/or diastolic blood pressure >90 mmHg) or occurrence of grade III-IV heart failure or myocardial infarction, cardiac angioplasty or stent placement, unstable angina pectoris, or other clinically significant heart diseases within one year prior to signing the ICF; QTc interval >450 ms for males or QTc interval >470 ms for females during screening (QTc interval calculated using the Fridericia formula);
• Presence of any indwelling catheter or drainage tube (e.g., percutaneous nephrostomy tube, indwelling catheter, bile drainage tube or pleural/peritoneal/pericardial catheter), except any dedicated central venous catheter;
• A history of or any central nervous system disorders, such as epileptic seizure, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, or any autoimmune disease involving the central nervous system;
• A positive result obtained in any of the following virological tests:
• Antibody to human immunodeficiency virus (HIV antibody);
• Hepatitis C virus antibody (HCV antibody), with a positive result for hepatitis C virus ribonucleic acid (HCV RNA);
• Positive for hepatitis B surface antigen (HBsAg); or positive for hepatitis B core antibody (HBcAb) and positive for hepatitis B virus deoxyribonucleic acid (HBV DNA) copies;
• Treponema pallidum antibody (TP antibody); patients may be enrolled after additional examinations are performed to exclude active syphilis where necessary;
• Fungal, bacterial, viral or other infections or suspected fungal, bacterial, viral or other infections that cannot be controlled or require intravenous administration;
• Significant tendency for bleeding, such as active gastrointestinal bleeding, coagulation disorders;
• Patients with a history of severe allergy or allergic constitution;
• A history of autoimmune diseases (e.g., Crohn's disease, rheumatoid arthritis and systemic lupus erythematosus) requiring systemic immunosuppressive/systemic disease-modulating drugs in the past 2 years;
• Interstitial lung disease (such as pneumonia, pulmonary fibrosis), or a history of clinically significant respiratory system diseases during screening;
• History of organ transplantation;
• Use of granulocyte colony-stimulating factor (G-CSF) or granulocyte-macrophage colony-stimulating factor (GM-CSF) within 2 weeks prior to leukapheresis;
• Receipt of gene therapy or other cell therapies with the same target within the past 6 months;
• Participation in any other clinical trial within 4 weeks prior to signing the informed consent form, or the date of signing the informed consent form still within 5 half-lives of the drug from the last dose in the last clinical trial (whichever is longer);
• Patients with poor compliance due to physiological, family, social, geographic and other factors, and failure to follow the study protocol and the follow-up plan;
• Patients with contraindications to cyclophosphamide, fludarabine, IL-2, or other drugs related to the study treatment;
• Comorbidities requiring treatment with systemic corticosteroids (dexamethasone at a dose of ≥5 mg/day or other corticosteroids at the equivalent dose) or other immunosuppressive drugs within 12 weeks after the study treatment starts as judged by the investigator;
• Women who are breastfeeding and are unwilling to stop breastfeeding;
• Any other conditions that are, in the opinion of the investigator, not suitable for enrollment.
