Stereotactic Body Radiation and Tumor Treating Fields for Locally Advanced Pancreas Cancer
- Conditions
- Pancreas CancerLocally AdvancedLocally Advanced Pancreatic Adenocarcinoma
- Interventions
- Radiation: Stereotactic Ablative Body Radiation (SABR)Device: Tumor Treating Fields (TTF)
- Registration Number
- NCT05679674
- Lead Sponsor
- Baptist Health South Florida
- Brief Summary
The purpose of this clinical trial is to determine whether using chemotherapy followed by stereotactic ablative body radiation therapy (SABR) and tumor treating fields (TTF) will slow tumor growth in people with locally advanced pancreas cancer. All participants will receive SABR therapy once per day for five days and use the TTF system for at least 18 hours per day starting on the first day of SABR until the tumor progresses or severe toxicity develops.

-
People of childbearing potential must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry and for the duration of study participation. Should a participant become pregnant or suspect they are pregnant while participating in this study, they must inform the treating physician immediately.
-
Able to operate the tumor treating field (NovoTTF-100L) system independently or with assistance.
-
All participants must sign written informed consent.
-
Distant metastasis from pancreas cancer.
-
Contraindication to having a magnetic resonance imaging (MRI) scan.
-
Prior abdominal radiation therapy.
-
History of any primary malignancy with the exception of:
- Malignancy treated with curative intent and with no known active disease for at least 3 years before enrollment on this study.
- Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease.
- Adequately treated carcinoma in situ without evidence of disease (i.e., cervical carcinoma in situ; superficial bladder cancer).
-
Any unresolved toxicity (Common Terminology Criteria for Adverse Events version 5.0 > grade 2) from previous anti-cancer therapy. Participants with irreversible toxicity that is not reasonably expected to worsen by treatment on this study are permitted to enroll on this study.
-
History of inflammatory bowel disease (i.e., Crohn's disease, ulcerative colitis).
-
Any condition in the opinion of the investigator that would interfere with evaluation of study treatment or interpretation of patient safety or study results.
-
Participants who are pregnant or breastfeeding. Patients with an electrical implantable device in the torso. Examples of electrical implanted medical devices include spinal cord stimulators, vagus nerve stimulators, pacemakers, and defibrillators.
-
History of significant uncontrolled cardiovascular disease. Significant cardiac disease includes second/third degree heart block; significant ischemic heart disease; poorly controlled hypertension; congestive heart failure of the New York Heart Association (NYHA) Class II or worse.
-
History of arrhythmia that is symptomatic or requires treatment. Patients with atrial fibrillation or flutter controlled by medication are not excluded from participation in the trial.
-
Known allergy to medical adhesives or conductive hydrogel [gel used on electrocardiogram (ECG) stickers or transcutaneous electrical nerve stimulation (TENS) electrodes].

Group Intervention Description Stereotactic Ablative Body Radiation (SABR) and Tumor Treating Fields (TTF) Tumor Treating Fields (TTF) 50 Gy in five fractions SABR (once per day for 5 days) and use of the TTF system for 18 hours per day starting on the first day of SABR and continuing until abdominal disease progression Stereotactic Ablative Body Radiation (SABR) and Tumor Treating Fields (TTF) Stereotactic Ablative Body Radiation (SABR) 50 Gy in five fractions SABR (once per day for 5 days) and use of the TTF system for 18 hours per day starting on the first day of SABR and continuing until abdominal disease progression
- Primary Outcome Measures
Name Time Method Median Progression Free Survival (PFS) 2 years PFS is defined as the time from the initiation of study therapy to the first documented disease progression or death due to any cause, whichever occurs first
- Secondary Outcome Measures
Name Time Method Change in Local Control (LC) 1 and 2 years LC is defined as a response within the radiation target volume according to RECIST) v1.1 criteria (i.e., percentage of participants with stable disease, partial response, or complete response).
Change in Overall Survival (OS) 1 and 2 years OS is defined as the time from the initiation of study therapy to death due to any cause or date of last follow-up, whichever occurs first.
Median Local Control (LC) 2 years LC is defined as a response within the radiation target volume according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 criteria (i.e., percentage of participants with stable disease, partial response, or complete response).
Change in Incidence of Grade 3+ Toxicities Baseline, during radiation therapy, every 3 months for 2 years All participants will be evaluable for toxicity from the time of their first treatment. All Grade 3+ toxicities \[according to Common Terminology Criteria for Adverse Events (CTCAE) version 5.0\] will be tracked, regardless of attribution to study treatment.
Location of Recurrence 2 years Location of recurrence is defined as the site(s) at the time of any first tumor recurrence: local only \[centroid of the recurrence within the planning target volume (PTV)\], distant only (centroid of the recurrence outside of the PTV), or local and distant.
Median Distant Metastasis Free Survival (DMFS) 2 years DMFS is defined as the time from initiation of study therapy to the first radiographic confirmation of distant metastasis
Change in Distant Metastasis Free Survival (DMFS) 1 and 2 years DMFS is defined as the time from initiation of study therapy to the first radiographic confirmation of distant metastasis
Median Overall Survival (OS) 2 years OS is defined as the time from the initiation of study therapy to death due to any cause or date of last follow-up, whichever occurs first.
Change in Quality of Life (QOL) Baseline, during radiation therapy, every 3 months for 2 years Quality of Life will be assessed using the Functional Assessment of Cancer Therapy - General (FACT-G), a 27-item questionnaire designed to measure four domains of QOL in cancer patients: physical, social, emotional, and functional well-being. Each domain has a scoring range of 0-28, for a combined total score of 0-108, where higher scores indicate better QOL.
Change in Progression Free Survival (PFS) 1 and 2 years PFS is defined as the time from the initiation of study therapy to the first documented disease progression or death due to any cause, whichever occurs first
Chemotherapy-Free Interval 2 years The chemotherapy-free interval is defined as the duration of time from the initiation of study therapy to the date any chemotherapy is subsequently administered.
