What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests a new device called DaRT that delivers a special type of radiation directly into pancreatic tumors. It is being combined with standard chemotherapy in 30 people with advanced or metastatic pancreatic cancer. The main goal is to see if the combination is safe, and also to check if it helps control pain and shrink tumors.

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) device
What this could lead to
If it works, this could offer a new way to control pancreatic tumors and improve survival when used with standard chemotherapy.
What could go wrong
This is an early safety study with only 30 participants, so results may not apply to everyone. The procedure is invasive and side effects are unknown.

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 newly diagnosed locally advanced inoperable pancreatic adenocarcinoma (Cohort 1) OR histologically and/or cytologically proven newly diagnosed metastatic pancreatic adenocarcinoma (Cohort 2). * Patients will start treatment with mFOLFIRINOX (up to 4 cycles) before DaRT insertion * Target lesion is technically amenable for Alpha DaRT sources implantation. * Measurable lesion per RECIST (version 1.1) criteria * Lesion size ≤ 5 cm in the longest diameter * Interstitial radiation indication validated by a multidisciplinary team. * ECOG Performance Status Scale 0 -2 * 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: * For Cohort 1 only: Borderline unresectable pancreatic cancer, and/or fit for surgical exploration unless patient refuses surgery. * For Cohort 1 and Cohort 2: Prior treatment for pancreatic cancer, including chemotherapy except for 1 - 4 cycles of mFOLFIRINOX, radiation therapy, immunotherapy, etc. * 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 DaRT insertion. * 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 DaRT insertion * Patients who are at high risk of complications from radiation due to genetic conditions/mutations, inflammatory bowel disease, or connective tissue disease.
