About this study
Official title: Efficacy and Safety of MRG003 With PD-1 Induction Followed by Capecitabine and PD-1 Maintenance as First-line Treatment in Locally Recurrent Nasopharyngeal Carcinoma
This study enrolls patients who have experienced local recurrence of nasopharyngeal carcinoma (NPC) with or without regional recurrence. The treatment regimen includes an induction phase with MRG003 at 2.0 mg/kg (D1) combined with Tislelizumab 200 mg (D1), administered weekly for 6 cycles. This is followed by maintenance therapy consisting of Capecitabine (650 mg/m², twice daily on days 1-21) in combination with Tislelizumab, continued for up to 1 year or until disease progression.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
MRG003Drug
MRG003 at 2.0 mg/kg (D1) will be administered every three weeks for 6 cycles
TislelizumabDrug
Tislelizumab 200 mg (D1) will be administered every three weeks for 6 cycles. Upon achieving an objective response, maintenance therapy will continue for up to one year or until disease progression is observed.

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

The Objective Response Rate (ORR) is defined as the proportion of patients achieving Complete Response (CR) or Partial Response (PR) by Day 21 after the completion of six cycles of MRG003 treatment, starting from the date of enrollment.
Measured: Day 21 after the completion of six cycles of MRG003 treatment
Secondary outcomes (4)
Progression-Free Survival (PFS)
PFS is defined as the time from enrollment to the date of tumor progression or death from any cause, or to the date of the last follow-up if no progression has occurred.
Measured: 1-year; 3-year
Overall Survival (OS)
OS is defined as the time from enrollment to the date of death from any cause, or to the date of the last follow-up if no death has occurred.
Measured: 1-year; 3-year
Duration of Response (DOR)
DOR is defined as the time from the first assessment of Complete Response (CR) or Partial Response (PR) to the first assessment of Progressive Disease (PD) or death from any cause
Measured: 1-year; 3-year
Disease Control Rate (DCR)
DCR is defined as the proportion of subjects who achieve Complete Response (CR), Partial Response (PR), or Stable Disease (SD) after treatment.
Measured: Day 21 after the completion of six cycles of MRG003 treatment

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing MRG003, Tislelizumab and Capecitabine in people with Nasopharyngeal Carcinoma and Local Recurrence, run by Fujian Cancer Hospital 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 4 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 Oct 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 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?
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 Qiaojuan Guo, PhD (591-83638732, guoqiaojuan@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Objective Response Rate (time frame: Day 21 after the completion of six cycles of MRG003 treatment). 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 19 Oct 2026.
