About this trial

This Phase 1 study will evaluate safety and the immune response to pooled mutant-KRAS peptide vaccine with poly-ICLC adjuvant for patients who have been identified to be at risk of developing pancreatic cancer.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

>/=55 years old or 10 years younger than the age of youngest relative with pancreatic cancer, and

Come from a family with 2 or more members with a history of pancreatic cancer (2 of which have a first-degree relationship consistent with familial pancreatic cancer), and

Have a first-degree relationship with at least one of the relatives with pancreatic cancer.

If there are 2 or more affected blood relatives, at least 1 must be a first-degree relative of the individual being screened.

Disqualifiers

If expected to require any other form of systemic or localized antineoplastic therapy while on study.

Within 4 weeks prior to first dose of study drug.

Within 4 weeks prior to first dose of study drug.

Any investigational device.

Trial design

Design model

Sequential

Treatments tested in this trial

  • Cohort A: Patients at high risk of developing pancreatic cancer.

    Drug

    1. KRAS peptide vaccine with poly-ICLC adjuvant will be administered on Prime week 1, 3, and 5. Boost vaccinations with will be administered at week 13. All subjects will return to the study site approximately 28 days (+ 7 days) after the last vaccination for an End of Treatment (EOT) and safety evaluation. 2. Drug: up to 1.8 mg KRAS peptide vaccine + 0.5mg Poly-ICLC

  • Cohort B: Patients must have evidence of a pancreatic cystic neoplasm

    Drug

    Patients will receive KRAS peptide vaccine with poly-ICLC adjuvant as two prime vaccinations on weeks 1 and 2. Surgery is considered standard of care. Surgery will occur at the discretion of the treating hepatobiliary surgeon and is not dictated by this protocol. Subjects will return to the study site approximately at week 4 (+ 7 days) for a safety evaluation prior to surgery. Subjects will have an End of Treatment (EOT) visit at study Week 8 (+ 7 days).
