About this study
Official title: Phase I Study of Autologous CD8+ and CD4+ Transgenic T Cells Expressing High Affinity KRASG12V Mutation-Specific T Cell Receptors in Participants With Metastatic Solid Tumors With KRAS G12V Mutations
This phase I trial studies the side effects and best dose of autologous CD8+ and CD4+ transgenic T cells expressing high affinity KRASG12V mutation-specific T cell receptors (FH-A11KRASG12V-TCR) and to see how well they work in treating patients with solid tumor cancers that has spread from where it first started (primary site) to other places in the body (metastatic). T cells are infection fighting blood cells that can kill tumor cells. The T cells given in this study will come from the patient and will have a new gene put in them that makes them able to recognize KRAS G12V, a protein on the surface of tumor cells. These KRAS G12V-specific T cells may help the body's immune system identify and kill KRAS G12V solid cancer tumor cells.
Read the detailed description
OUTLINE: This is a dose-escalation study of FHA11KRASG12V-TCR.
Patients undergo leukapheresis prior to treatment and receive lymphodepletion chemotherapy with either cyclophosphamide intravenously (IV) and fludarabine IV on days -6, -5, and -4, or bendamustine IV on days -4 and -3 at the discretion of the treating clinician and/or principal investigator (PI). Patients then receive FHA11KRASG12V-TCR IV on day 0. Patients may receive an additional FHA11KRASG12V-TCR IV infusion as soon as 28 days or up to 1 year after the first infusion. Patients undergo echocardiography (ECHO) or multigated acquisition scan (MUGA) during screening. Patients also undergo computed tomography (CT), positron emission tomography (PET) or magnetic resonance imaging (MRI) as well as blood sample collection and a tissue biopsy at baseline and throughout the trial.
After completion of study treatment, patients are followed up on day 56, 112, 168, 224, 280 and day 365, then long-term for up to 15 years.

Primary outcome
Incidence of adverse events
Time frame: Within 1 year after 1st infusion of (autologous CD8+ and CD4+ transgenic T cells expressing high affinity KRASG12V mutation-specific T cell receptors (FH-A11KRASG12V-TCR)
Safety and tolerability should be evaluated after each infusion. Will be assessed by National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0 (NCI CTCAE v5.0).
Dose-limiting toxicity rates
Time frame: From the time of lymphodepletion chemotherapy to 28 days after FH-A11KRASG12V-TCR infusion
Will be assessed by treatment-related grade 3 or higher toxicity and assessed by NCI CTCAE v5.0. The treatment will be considered to have an acceptable safety profile if the observed toxicity rate is consistent with a true rate that does not exceed 35%.
Maximum tolerated dose of FH-A11KRASG12V-TCR
Time frame: From the time of lymphodepletion chemotherapy to 28 days after FH-A11KRASG12V-TCR infusion
Will be assessed by NCI CTCAE v5.0.
Recommended phase 2 dose of FH-A11KRASG12V-TCR
Time frame: Within 1 year after 1st infusion of FH-A11KRASG12V-TCR
Will be assessed by NCI CTCAE v5.0.
8 secondary outcomes
Reproducibly generating FHA11KRASG12V- TCR from autologous participant cells (Feasibility)
Time frame: Within 1 year after eligibility determination
Overall response rate (ORR)
Time frame: Within 1 year after 1st infusion of FH-A11KRASG12V-TCR
Stable disease (SD)
Time frame: Within 1 year after 1st infusion of FH-A11KRASG12V-TCR
Clinical benefit rate (CBR)
Time frame: Within 1 year after 1st infusion of FH-A11KRASG12V-TCR
ORR
Time frame: Within 1 year after 1st infusion of FH-A11KRASG12V-TCR
Progression-free survival
Time frame: From study registration to disease progression or death of any cause), assessed up to 1 year after 1st infusion of FH-A11KRASG12V-TCR
Overall survival
Time frame: From study registration to death of any cause, assessed up to 1 year after 1st infusion of FH-A11KRASG12V-TCR
Changes in tumor microenvironment
Time frame: Within 1 year after 1st infusion of FH-A11KRASG12V-TCR

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Bendamustine, Biopsy and Biospecimen Collection in people with Non-small Cell Lung Cancer and Pancreas Cancer, run by Fred Hutchinson Cancer Center at 1 site in United States.
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 40 inclusion and 12 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 20 Oct 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 United States. 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 Fred Hutch Intake (206-606-1024, hutchdoc@fredhutch.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of adverse events (time frame: Within 1 year after 1st infusion of (autologous CD8+ and CD4+ transgenic T cells expressing high affinity KRASG12V mutation-specific T cell receptors (FH-A11KRASG12V-TCR)). The study lists 4 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 20 Oct 2026.
