GRECO-2: GC4711 + SBRT for pancreatic cancer - Clinical Trial

We are doing this study to find out how the experimental drug (GC4711) works in your body and against your cancer when combined with radiation therapy.

People with localized pancreatic cancer

Adults ages 18+ who:
- Have pancreatic cancer that has not spread (nonmetastatic) but cannot be treated with surgery
- Plan to have chemotherapy and radiation treatment for your cancer
- Have normal organ function
- Have not had radiation to the same area before
- Agree to use contraception (birth control) while in the study if you are able to have children

For more information about who can be in this study, please contact the study team.

The study has three parts: a screening period, a study dosing period, and a follow-up period.

If you choose to join the study, you will:
- Go through a screening period that includes a review of your medical record, test results, and one clinic visit
- Have radiation therapy called stereotactic body radiation therapy (SBRT) and chemotherapy, which are standard of care for your disease

During the dosing period of this study, you will:
- Be randomized (like flipping a coin) to one of two groups:
-- Group 1: Get the study drug (GC4711) in your vein and radiation for 5 days
-- Group 2: Get a placebo (harmless sugar water) in your vein and radiation for 5 days

During the follow-up time you will:
- Have regular study visits for 5 years.
- Have a physical exam, vital signs assessed, be asked about your side effects and any medications you are taking at each visit.
- Have blood samples taken, a CT and/or MRI scan, an electrocardiogram (ECG) and complete surveys questionnaires about how you are feeling
