About this study
Official title: Phase I/II Trail Evaluating Carbon Ion Radiotherapy (3 GyE Per Fraction) for Salvaging Treatment of Locally Recurrent Nasopharyngeal Carcinoma
The purpose of this study is to determine the maximal tolerated dose (MTD) of re-irradiation using carbon ion radiotherapy (CIRT) with the fraction size of 3 gray equivalent (GyE) in the treatment of locally recurrent nasopharyngeal cancer (NPC) and to evaluate the efficacy of such treatment at the MTD. Participants will be treated with CIRT with escalating dose regimens to evaluate the MTD in terms of acute and subacute toxicity observed within 4 months after the completion of CIRT. Once the MTD for locally recurrent NPC is determined, the MTD will be used as the recommended dose to patients fulfilling the inclusion criteria in the Phase II part of the trial.

The purpose of this study is to determine the maximal tolerated dose (MTD) of re-irradiation using carbon ion radiotherapy (CIRT) with the fraction size of 3 GyE in the treatment of locally recurrent nasopharyngeal cancer (NPC) and to evaluate the efficacy of such treatment at the MTD. Participants will be treated with CIRT with escalating dose starting from 54GyE (3GyE/daily fraction) to potentially 63GyE (3GyE/daily fraction) to evaluate the maximal tolerated dose (MTD) in terms of acute and subacute toxicity observed during and within 4 months after the completion of CIRT. The TITE-CRM method is used for the phase I dose escalating part of the trial and approximately 25 patients will be accrued. Once the MTD for locally recurrent NPC is determined, the MTD will be used as the recommended dose to patients fulfilling the inclusion criteria in the Phase II part of the trial. The Phase II part of the trial will be a single stage single arm study.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Carbon ion radiotherapy (CIRT)Radiation
Five dose levels (51GyE, 54GyE, 57GyE, 60GyE, 63GyE) are planned within the Phase I part. And the started dose level will be 54GyE. Daily fraction of 3 GyE will be delivered for all dose levels. After the recommended dose (RD), i.e., maximal tolerated dose, is determined or if the treatments to 63 GyE are safely delivered, the recommended dose (or 63 GyE) will be the prescribed dose in the Phase II part of the study.
| Study group | Role | What they receive |
|---|---|---|
| CIRT Arm (3GyE per fraction) | Experimental | Patients included in this arm were treated with carbon ion radiotherapy with a fraction size of 3GyE. Receives: Radiation: Carbon ion radiotherapy (CIRT) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 (phase 1)
The primary objective of phase 1 is to identify the maximum tolerated dose which is defined as the highest dose associated with a probability of dose limiting toxicity <=25%.
Measured: Within 4 months after the completion of treatment
Phase 2: Overall survival (OS)
Overall survival (OS) was defined as the time frame from enrollment to the date of death from any cause.
Measured: 2 years
Secondary outcomes (1)
Phase 2: Progression-free survival
Progression-free survival (PFS) was defined as the time frame from enrollment to the date of disease progression or death whichever came first.
Measured: 2 years

The purpose of this study is to determine the maximal tolerated dose (MTD) of re-irradiation using carbon ion radiotherapy (CIRT) with the fraction size of 3 gray equivalent (GyE) in the treatment of locally recurrent nasopharyngeal cancer (NPC) and to evaluate the efficacy of such treatment at the MTD. Participants will be treated with CIRT with escalating dose regimens to evaluate the MTD in terms of acute and subacute toxicity observed within 4 months after the completion of CIRT. Once the MTD for locally recurrent NPC is determined, the MTD will be used as the recommended dose to patients fulfilling the inclusion criteria in the Phase II part of the trial.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Carbon ion radiotherapy (CIRT) in people with Nasopharyngeal Carcinoma, run by Shanghai Proton and Heavy Ion Center at 1 site in China.
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 7 inclusion and 5 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: finished, as of the sponsor's last update on 7 Aug 2025. 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 combined 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.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 (phase 1) (time frame: Within 4 months after the completion of treatment). 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?
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 7 Aug 2025.
