About this study
This is a single-arm, open-label clinical study to evaluate the safety, tolerability and preliminary efficacy of IX001 TCR-T injection in advanced pancreatic cancer patients with KRAS G12V mutation.
Read the detailed description
This study will enroll participants with advanced pancreatic cancer patients with KRAS G12V mutation. The study consists of screening period, leukapheresis period, lymphodepletion period, treatment period, observation period and follow-up period. A total of 9-12 evaluable patients are planned to be recruited. The study is planned to be conducted using the "3 + 3" dose escalation design in two dose groups, and a single dose of the study drug will be administered at the dose levels of 3 × 10^9 ± 30% cells and 1 × 10^10 ± 30% cells. Subjects will be enrolled sequentially and treated by IX001 TCR-T injection at the corresponding planned dose level. All subjects who have received IX001 TCR-T injection will be followed for safety and efficacy up to 2 years.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing IX001 TCR-T injection, Fludarabine and Cyclophosphamide in people with Pancreatic Cancer, run by Sun Yat-sen University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 8 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Yuhong Li (87342487 ext. 020, liyh@sysucc.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Dose-limiting Toxicity (DLT) (time frame: 4 weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jan 2026; AzTrials last refreshed its copy on 26 Oct 2026.
