About this study
Official title: Phase I Study of NBTXR3 Activated by Radiotherapy for Locally Advanced or Borderline Resectable Pancreatic Ductal Adenocarcinoma
To find the recommended dose of NBTXR3 that can be given in combination with radiation therapy to patients with pancreatic cancer. To learn if the dose NBTXR3 found in Part 1 can help to control the disease.
Read the detailed description
PRIMARY OBJECTIVE:
- To determine the recommended phase II dose (RP2D) of NBTXR3 activated by radiotherapy in subjects with locally advanced or borderline-resectable pancreatic ductal adenocarcinoma.
SECONDARY OBJECTIVES:
- To evaluate the safety and feasibility of NBTXR3 intratumoral injection activated by radiotherapy in locally advanced or borderline-resectable pancreatic ductal adenocarcinoma
- To evaluate the anti-tumor response of NBTXR3 intratumoral injection activated by radiotherapy in subjects with locally advanced or borderline-resectable pancreatic ductal adenocarcinoma
- To evaluate time-to-event outcomes in subjects with locally advanced or borderline-resectable pancreatic ductal adenocarcinoma
EXPLORATORY OBJECTIVES:
- To evaluate the body kinetic profile of intratumorally injected NBTXR3.
- To evaluate time to event outcomes for subjects with clinical staging of locally advanced, unresectable disease.
- To evaluate resectability conversion rates.
- To evaluate surgical outcomes in subjects who undergo surgery after radiation therapy.
- To associate radiomic measurements with outcomes.
- To evaluate biomarkers of response in subjects treated with NBTXR3/RT.
OUTLINE: This is a dose-escalation study of NBTXR3.
Patients receive NBTXR3 intratumorally (IT) on day 1. Patients then undergo 15 fractions of intensity modulated radiation therapy (IMRT) between days 15-43 in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 1 month and then every 3 months for up to 1 year.

What is being measured
The primary outcome is the main question the study is designed to answer.
Dose-limiting toxicities
Any grade >= 3 adverse event related to NBTXR3 and/or radiation therapy. Any toxicity (grade >= 3) that is at least possibly related to study drug (NBTXR3) is a DLT. Adverse events will be scored based on National Cancer Institute - Common Terminology Criteria for Adverse Events (NCI-CTCAE v 5.0).
Measured: 4 weeks after last radiation dose
Maximum tolerated dose (MTD)
MTD will be determined as the dose for which the isotonic estimate of the toxicity rate is closest to the target toxicity rate 30%.
Measured: Up to 1 year
Recommended phase II dose (RP2D)
Measured: Up to 1 year
Secondary outcomes (3)
Determination of the feasibility of NBTXR3 injection in pancreas
Feasibility refers to the ability to do intratumoral injection of NBTXR3. The outcome for each patient would be "feasible" or "not feasible."
Measured: Up to 1 year
Progression free survival (PFS)
Measured: From NBTXR3 injection to local recurrence, local progression, distant progression, or death from any cause, whichever occurs first, assessed up to 1 year
Overall survival (OS)
Measured: From NBTXR3 injection to death from any cause or EoS, whichever occurs first, assessed up to 1 year

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Hafnium Oxide-containing Nanoparticles NBTXR3 and Radiation Therapy in people with Borderline Resectable Pancreatic Adenocarcinoma and Locally Advanced Pancreatic Ductal Adenocarcinoma, run by M.D. Anderson Cancer Center at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 27 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 22 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Dose-limiting toxicities (time frame: 4 weeks after last radiation dose). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 May 2026.
