Phase II Study to Evaluate Modified Folfirinox and Stereotactic Body Radiation Therapy in Non-metastatic Unresectable Pancreatic Adenocarcinoma

December 22, 2025 updated by: Yale University
The purpose of this study is to evaluate the efficacy of modified FOLFIRINOX followed by stereotactic body radiotherapy (SBRT) in patients with borderline resectable pancreatic cancer (BRPC) and locally advanced pancreatic cancer (LAPC). The primary hypothesis will be to determine if modified FOLFIRINOX followed by SBRT improves progression free survival (PFS) compared to historical controls treated with gemcitabine-based chemotherapy with or without standard fractionated radiation.

Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The Primary and Secondary are listed below.

Primary Objective:

- To evaluate progression free survival after modified FOLFIRINOX and SBRT in borderline resectable and locally advanced pancreatic cancer.

Secondary Objective:

  • To evaluate the radiographic response to FOLFIRINOX and SBRT by comparing IV contrast CT scans before and after therapy.
  • To determine rates of recurrence (local only, systemic only, and both local and systemic), and overall survival.
  • To determine rates of grade 3 or greater gastrointestinal toxicity, including acute toxicities occurring within 3 months of treatment, and late toxicities occurring over 3 months after completion of radiation.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Progression Free Survival
Time Frame: 9 months
Progression-free survival (PFS) at will be judged by CT scan and Response evaluation criteria in solid tumors (RECIST).

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
