Features of primary and adaptive immunotherapy resistance in microsatellite instable cancers

What is the Purpose of this Study?

If you choose to join this study, you will:
- Go through a screening period to see if you're eligible for the study
- Start participating before, during, or after treatment with standard of care immunotherapy for your cancer

If you're eligible to join, you will:
- Be monitored until you complete your immunotherapy treatment and the final blood and/or tissue samples are collected
- Provide the following depending on when you enroll in the study (before, during, or after immunotherapy):
-- Blood samples
-- Stool samples
-- Tumor tissue samples
What is the Condition Being Studied?
Stage III unresectable colorectal cancer or stage IV endometrial, prostate, or gastrointestinal cancer

Who Can Participate in this Study?

Adults ages 18 and older who:

- Are diagnosed with stage III or IV endometrial, prostate, hepatobiliary, pancreatic, and gastrointestinal cancers with certain tumor mutations

- Do not have prostate tumors with small cell component

- Are not pregnant or breastfeeding

Age Group
Adults
Participating Institutions

What is Involved?

We are doing this study to examine genetic changes in your tumor that may contribute to resistance to immunotherapy. With this information, we hope to be able to identify new treatment methods as well as improve our ability to identify patients more likely to respond to immunotherapy.
