About this study

This is a single-arm, phase I clinical study designed to evaluate the safety and feasibility of SCART (Stereotactic Centralized Ablative Radiation Therapy) dose escalation in patients with locally advanced pancreatic cancer. Pancreatic cancer carries a dismal prognosis, and the majority of patients are not surgical candidates at diagnosis. Radiotherapy is an important local treatment modality, but conventional approaches have shown limited efficacy. SCART is intended to deliver higher ablative doses to the tumor core while minimizing toxicity to surrounding normal tissues. In this trial, eligible patients will receive SCART with escalating dose levels using a standard 3+3 design. The primary endpoints are to determine the dose-limiting toxicity (DLT) and the maximum tolerated dose (MTD). Secondary endpoints include overall survival (OS), local control rate (LCR), and objective response rate (ORR).

Read the detailed description

Pancreatic cancer is among the most aggressive malignancies and is associated with poor prognosis. The 5-year survival rate remains below 10%, and most patients present with unresectable disease at diagnosis. Radiotherapy plays a pivotal role in local disease control, yet conventional fractionated radiotherapy (CFRT) has demonstrated limited survival benefits. Stereotactic body radiotherapy (SBRT) allows delivery of higher biologically effective doses with improved local control, but further dose escalation is restricted by normal tissue tolerance.

SCART (Stereotactic Centralized Ablative Radiation Therapy) is an innovative technique that delivers ablative radiation doses to selected intratumoral sub-volumes while maintaining lower doses at the tumor periphery. This spatial dose distribution has the potential to induce bystander effects and enhance biological efficacy beyond that achievable with uniform SBRT.

This phase I study is designed to evaluate the safety and feasibility of SCART dose escalation in patients with locally advanced pancreatic cancer. Patients will be enrolled into sequential dose cohorts (10 Gy, 13 Gy, 16 Gy, and 19 Gy per fraction within the SCART region) using a standard 3+3 dose-escalation design. All patients will also receive background SBRT (25 Gy in 5 fractions) covering the gross tumor volume and margin.

The primary objective is to determine dose-limiting toxicities (DLTs) and establish the maximum tolerated dose (MTD) of SCART. Secondary objectives include overall survival (OS), local control rate (LCR), objective response rate (ORR), and treatment-related adverse events (AEs). Exploratory analyses will investigate potential biomarkers and immune response modulation associated with SCART.

The estimated enrollment is 12-24 patients, with an accrual period of 24 months and a minimum follow-up of 12 months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximum Tolerated Dose (MTD)

    The maximum tolerated dose (MTD) of SCART (Stereotactic Centralized Ablative Radiation Therapy) will be determined using a standard 3+3 dose-escalation design. MTD is defined as the highest dose level at which the incidence of dose-limiting toxicities (DLTs), graded according to CTCAE v5.0, does not exceed 33% of patients in that cohort.

    Measured: Within 90 days after completion of radiotherapy

  2. Dose-Limiting Toxicities (DLTs)

    Incidence of dose-limiting toxicities (DLTs) graded according to the National Cancer Institute Common Terminology CTCAE v5.0. DLTs will be evaluated during the dose-escalation phase to assess the safety of SCART (Stereotactic Centralized Ablative Radiation Therapy).

    Measured: Within 90 days after completion of radiotherapy

Secondary outcomes (4)
  1. Overall Survival (OS)

    Overall survival will be defined as the time from the start of SCART treatment to death from any cause. Patients still alive at the time of analysis will be censored at the date of last follow-up.

    Measured: Up to 12 months after enrollment

  2. Local Control Rate (LCR)

    Local tumor control will be assessed according to RECIST v1.1 criteria based on radiographic imaging (CT/MRI). Local control rate will be calculated as the proportion of patients without local progression.

    Measured: Up to 12 months after enrollment

  3. Objective Response Rate (ORR)

    Objective tumor response will be evaluated using RECIST v1.1 criteria by imaging assessment.

    Measured: Up to 12 months after enrollment

  4. Adverse Events (AEs)

    Incidence and severity of treatment-related adverse events (AEs) will be graded according to CTCAE v5.0 during and after radiotherapy.

    Measured: Up to 12 months after enrollment

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted15 Sep 2025
  2. Study start10 Sep 2025
  3. Primary completion1 Sep 2028 (estimated)

Why it stopped: The study was terminated early due to slow patient accrual. Enrollment was substantially lower than anticipated, making it unlikely to achieve the planned sample size within a reasonable timeframe.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 3 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: paused, as of the sponsor's last update on 1 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 China. 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?

Results are not available in the source record.

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?

Maximum Tolerated Dose (MTD) (time frame: Within 90 days after completion of radiotherapy). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07173374, which also lists 20 linked publications.

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 1 May 2026.
