Master Protocol of TCR-modified T Cell Therapy Targeting HLA-restricted KRAS Antigen Administered in Adult Patients With Metastatic or Locally Advanced PDAC

Who May Qualify: 1. Adult patient (18 years or older) with newly diagnosed metastatic PDAC or locally advance PDAC disease. 2. HLA genotyping confirmed with a high-resolution method. 3. Confirmed KRAS G12V or KRAS G12D mutation in tumour using biopsy sample. 4. Fertile male and female patients must use a highly effective contraceptive method before, during, and for at least 6 months after the last mutKRAS TCR infusion. Acceptable contraception for women includes implants, injectables, combined oral contraceptives, intrauterine devices (IUDs), sexual abstinence, or a partner who has been vasectomized for at least 6 months. Acceptable contraception for male includes having had a vasectomy for at least 6 months, sexual abstinence, to condoms plus spermicide. Fertile female and male patients must adhere to any treatment-specific pregnancy prevention guidelines for cyclophosphamide (refer to SmPC). 5. Confirmed clinical benefit to SoC treatments and absence of disease progression according to the PI judgement. 6. Measurable disease by RECIST 1.1 criteria at the time of first treatment. Baseline imaging (for example, diagnostic CT chest/abdomen/pelvis and imaging of the affected extremity or brain, as appropriate), magnetic resonance imaging (MRI or CT scan) must be obtained within 8 weeks of the first planned T cell infusion. CT can be substituted for MRI in patients unable to have CT contrast. Who Should NOT Join This Trial: 1. Another malignancy other than PDAC. 2. Current or history of brain metastasis. 3. Patient with known genetic status for whom other treatments are available e.g. BRCA, MSI-H. Always talk to your doctor about whether this trial is right for you.
