Can fasting lower pancreatic cancer risk? small study aims to find out
NCT ID NCT07513116
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study will test whether intermittent fasting (eating only during an 8-hour window each day) is safe and doable for 20 people at high risk for pancreatic cancer. Researchers will also check if this eating pattern changes certain markers in the body linked to cancer risk. The goal is to gather early information, not to prove that fasting prevents cancer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- intermittent fasting
- What this could lead to
- If successful, this could point toward a lifestyle approach to reduce pancreatic cancer risk in high-risk individuals.
- What could go wrong
- This is a very small, early feasibility study with only 20 participants. It is not designed to prove that fasting prevents cancer, and results may not apply to everyone.

Inclusion Criteria * Participants ≥ 18 years old. Participants under 18 are excluded due to their potential inability to understand and consent independently to the methods required for the study drug use and its potential risks and benefits. * Participants evaluated and classified as high risk for pancreatic cancer through a High-Risk Pancreatic Cancer Clinic or High-Risk Pancreatic Cyst Clinic, based on established clinical assessment and risk stratification. * High-risk status may include one or more of the following: * Hereditary cancer syndromes or known pathogenic germline mutations associated with pancreatic cancer risk * Family history of pancreatic ductal adenocarcinoma (PDAC) * Presence of pancreatic cysts or precursor lesions (e.g., IPMN, MCN) * New-onset diabetes mellitus is considered suspicious for pancreatic cancer * History of recurrent or chronic pancreatitis * Eligibility and surveillance risk assessment must be consistent with NCCN (National Comprehensive Cancer Network) Guidelines for Pancreatic Cancer Screening in High- Risk Individuals. * Participants are able to understand and are willing to sign a written informed consent document. * Both English-speaking and non-English-speaking participants are eligible for participation * Participants are willing to make a change in eating time patterns. * Participants are willing to provide App-tracked fasting time data over the course of the study. Exclusion Criteria * BMI \< 18.5 Kg/m2 * Documented history of symptomatic hypoglycemia * Pregnant or breastfeeding women * Cognitively impaired individuals
