About this study
In the IMRT era, patients with stage II-III (AJCC8th) nasopharyngeal carcinoma achieve high local control. However, survivors are increasingly experiencing late radiation-induced toxicities. A previous study found that reducing the radiation dose to the primary site to 60Gy for patients who achieved partial or complete response to induction chemotherapy resulted in a lower rate of late toxicities and an inferior local control rate. The investigators aim to reduce the radiation dose to the primary site for patients after immunochemotherapy, given the potential of neoadjuvant chemotherapy and immunotherapy to increase response rates and long-term survival. The protocol includes participants with stage II-III (AJCC8th), except T2N0M0, to receive three courses of neoadjuvant gemcitabine plus cisplatin and Toripalimab. If the primary tumour regresses by over 75%, de-escalated radiotherapy with 60Gy will be administered, and participants will receive two cycles of cisplatin and three cycles of Toripalimab during the radiotherapy course. Otherwise, participants will receive conventional radiotherapy and concurrent chemotherapy with cisplatin for two cycles as usual. The aim of this study is to investigate the 3-year local control rate and toxicities of de-escalated radiotherapy.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
de-escalated radiotherapyRadiation
Enrolled patients receive three courses of induction therapy with gemcitabine and cisplatin, along with Toripalimab. After induction therapy, patients with a tumor volume regression of 75% or more and no detectable EBV DNA will receive de-escalated radiotherapy for the primary tumor with 60 Gy. During radiotherapy, patients will receive Cisplatin 100 mg/m2 every three weeks for two courses and Toripalimab 240 mg every three weeks for three courses. If patients do not achieve complete remission at the end of radiotherapy, 6 Gy will be added to the residual lesions.
conventional radiotherapyRadiation
Enrolled patients receive three courses of induction therapy with gemcitabine and cisplatin, along with Toripalimab. After induction therapy, patients with tumor volume regression less than 75% or EBV DNA copy number higher than 0 receive conventional radiotherapy for the primary tumor with 70 Gy. Patients will receive Cisplatin 100 mg/m2, every three weeks for two courses during radiotherapy.
| Study group | Role | What they receive |
|---|---|---|
| de-escalated radiotherapy | Experimental | If the primary tumour regresses by over 75% and the level of EBV DNA reduces to zero, a radiation dose of 60Gy will be administered. Additionally, three cycles of Toripalimab (240mg, every three weeks) and two cycles of cisplatin (100mg/m2, every three weeks) will be given during radiotherapy. Receives: Radiation: de-escalated radiotherapy |
| conventional radiotherapy | Other | If the primary tumour regresses by less than 75% or if EBV DNA remains above zero, a conventional radiation dose of 70Gy to the primary tumor and two cycles of cisplatin (100mg/m2, every three weeks) will be administered during radiotherapy. Receives: Radiation: conventional radiotherapy |

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
In the IMRT era, patients with stage II-III (AJCC8th) nasopharyngeal carcinoma achieve high local control. However, survivors are increasingly experiencing late radiation-induced toxicities. A previous study found that reducing the radiation dose to the primary site to 60Gy for patients who achieved partial or complete response to induction chemotherapy resulted in a lower rate of late toxicities and an inferior local control rate. The investigators aim to reduce the radiation dose to the primary site for patients after immunochemotherapy, given the potential of neoadjuvant chemotherapy and immunotherapy to increase response rates and long-term survival. The protocol includes participants with stage II-III (AJCC8th), except T2N0M0, to receive three courses of neoadjuvant gemcitabine plus cisplatin and Toripalimab. If the primary tumour regresses by over 75%, de-escalated radiotherapy with 60Gy will be administered, and participants will receive two cycles of cisplatin and three cycles of Toripalimab during the radiotherapy course. Otherwise, participants will receive conventional radiotherapy and concurrent chemotherapy with cisplatin for two cycles as usual. The aim of this study is to investigate the 3-year local control rate and toxicities of de-escalated radiotherapy.

Questions about this trial
What is this clinical trial studying?
A study testing de-escalated radiotherapy and conventional radiotherapy in people with Nasopharyngeal Carcinoma and Radiotherapy; Complications, run by Sun Yat-sen University 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 13 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: looking for participants now, as of the sponsor's last update on 19 Mar 2024. 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.
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?
Contact Puyun Ouyang (+8602087342926, ouyangpy@sysucc.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
local recurrence rate(LRR) (time frame: 3 years). 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 NCT06313450, which also lists 9 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 19 Mar 2024.
