Radioactive 'Seeds' take on pancreatic cancer
NCT ID NCT06755359
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new approach for locally advanced pancreatic cancer: tiny radioactive sources placed directly into the tumor to deliver alpha radiation. The treatment is combined with standard chemotherapy. The main goal is to check safety in 40 participants, but researchers will also look at whether it shrinks tumors and improves survival.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Diffusing Alpha Radiation Emitters Therapy (DaRT) - radioactive sources inserted into the tumor
- What this could lead to
- If successful, this could offer a new treatment option for locally advanced pancreatic cancer by combining targeted radiation with chemotherapy to control the disease.
- What could go wrong
- This is an early safety study with only 40 participants, so effectiveness is not yet proven. The procedure involves inserting radioactive sources into the tumor, which carries risks like infection or damage to nearby organs.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Histologically and/or cytologically proven locally advanced pancreatic adenocarcinoma * Target lesion is technically amenable for Alpha DaRT sources implantation. * Measurable lesion per RECIST (version 1.1) criteria * Stable disease or tumor response per RECIST (version 1.1) criteria compared to before initiation of mFOLFIRINOX * Lesion size ≤ 5 cm in the longest diameter * Interstitial radiation indication validated by a multidisciplinary team which includes an oncologist, a radiation oncologist, radiologist, gastroenterologist and a surgeon specialized in pancreatic oncology in the case that a surgical emergency occurs during the procedure * Patients have received 8 - 12 cycles of mFOLFIRINOX * ECOG Performance Status Scale 0 - 1 * Life expectancy is more than 6 months * WBC ≥ 3500/µl, granulocyte ≥ 1500/µl * Platelet count ≥60,000/µl * Creatinine ≤1.9 mg/dL * AST and ALT ≤ 2.5 X upper limit of normal (ULN) * INR \< 1.4 for patients not on Warfarin * Age ≥18 years old * Subjects are willing and able to sign an informed consent form * Women of childbearing potential (WOCBP) will have evidence of negative pregnancy test before the Ra-224 implantation and are required to use an acceptable contraceptive method to prevent pregnancy for 3 months after initiation of Alpha DaRT therapy * Patients must agree to use adequate contraception (vasectomy or barrier method of birth control) prior to study entry, for the duration of study participation and for 3 months after DaRT insertion. Exclusion Criteria: * Concomitant immunotherapy within the past 4 weeks. * Patients with metastatic disease * Borderline unresectable pancreatic cancer, and/or cases fit for surgical exploration unless patient refuses surgery. * Known hypersensitivity to any of the components of the treatment. * Patients undergoing systemic immunosuppressive therapy excepting intermittent, brief use of systemic corticosteroids. * Clinically significant cardiovascular disease, e.g. cardiac failure of New York Heart Association classes III-IV, uncontrolled coronary artery disease, cardiomyopathy, uncontrolled arrhythmia, uncontrolled hypertension, or history of myocardial infarction in the last 12 months. * Patients with uncontrolled intercurrent illnesses including, but not limited to an active infection requiring systemic therapy or a known psychiatric or substance abuse disorder(s) that would interfere with cooperation with the requirements of the trial or interfere with the study endpoints. * Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy, low risk prostate cancer, or in situ cervical cancer. * Patient requires treatment not specified in this protocol which may conflict with the endpoints of this study including evaluation of response or toxicity of DaRT. * Patients do not agree to use adequate contraception (vasectomy or barrier method of birth control) prior to study entry, for the duration of study participation and for 3 months after discontinuing therapy. * Volunteers participating in another interventional study in the past 30 days which might conflict with the endpoints of this study or the evaluation of response or toxicity of DaRT. * High probability of protocol non-compliance (in opinion of investigator). * Breastfeeding women or women of childbearing potential unwilling or unable to use an acceptable contraceptive method to prevent pregnancy for 3 months after RT.
