A Phase I Clinical Study of IX001 TCR-T Injection in the Treatment of Advanced Pancreatic Cancer Patients With KRAS G12V Mutation
Bu çalışma, KRAS geninde G12V mutasyonu ve uyumlu HLA-A*11:01 tipi bulunan ileri evre pankreas kanseri (pancreatic cancer) hastalarında IX001 TCR-T hücre tedavisini (fludarabin ve siklofosfamid ile birlikte) incelemektedir. Çalışmaya; 18-75 yaş arası, standart tedavisi başarısız olmuş, ameliyat edilemeyen lokal ileri veya metastatik pankreas duktal adenokarsinomu tanılı hastalar alınmaktadır. Sun Yat-sen University tarafından yürütülen çalışma Faz 1 aşamasında yürütülmekte ve halen katılımcı almaktadır.

Inclusion Criteria: * 1\. Voluntary signing of an informed consent form (for Human Leukocyte Antigen (HLA) typing and tumor gene mutation test, and main screening) * 2\.

Asymptomatic participants with a small amount of pleural effusion or ascites on imaging are allowed * 8\. Subjects who have experienced tumor-related intestinal or bowel obstruction within 6 months. including incomplete obstruction related to underlying disease or symptoms of intestinal obstruction requiring treatment * 9\.
