About this study

Official title: A Phase II Prospective, Single-Arm, Multicenter Clinical Study of Iparomlimab and Tuvonralimab Injection in the Treatment of Patients With Previously Untreated Locally Advanced Nasopharyngeal Carcinoma

This is a prospective, multicenter phase II clinical study. The subjects are patients with previously untreated locally advanced nasopharyngeal carcinoma, with clinical staging of IVA, T1-4, N3, M0. The study aims to preliminarily evaluate the efficacy and safety of Iparomlimab and Tuvonralimab Injectionin the treatment of these patients.

Read the detailed description

Research Objective: To preliminarily evaluate the efficacy and safety of Iparomlimab and Tuvonralimab Injection in the treatment of previously untreated locally advanced nasopharyngeal carcinoma patients.

Study Design: Prospective, multicenter phase II clinical study. Study Subjects: Previously untreated locally advanced nasopharyngeal carcinoma patients with clinical stage: IVA, T1-4, N3, M0.

Sample Size: It is assumed that the 3-year distant metastasis free survival (DMFS) rate of T1-4N3M0 nasopharyngeal carcinoma patients after standard treatment is 74%, and the 3-year DMFS rate after combining with Iparomlimab and Tuvonralimab Injection in the induction and adjuvant stages for T1-4N3M0 nasopharyngeal carcinoma patients is 90%. With a two-sided α=0.05 and power of 80%, and considering a 10% dropout rate, the total sample size is calculated to be 45 cases.

Inclusion Criteria: Refer to the corresponding section. Exclusion Criteria: Refer to the corresponding section. Treatment Plan: Eligible subjects are selected according to the inclusion and exclusion criteria. They will receive 3 courses of Iparomlimab and Tuvonralimab Injection during the induction chemotherapy period, undergo standard concurrent chemoradiotherapy as scheduled, and receive 9 cycles of Iparomlimab and Tuvonralimab Injection (5mg/kg, Q3W) in the adjuvant stage. This will continue until the researcher judges that the subject can no longer benefit, the disease progresses, intolerable toxicity occurs, the researcher decides to stop, the subject withdraws informed consent, or death occurs.

Study Endpoints:

Primary Study Endpoint: 3-year distant metastasis-free survival (DMFS). Secondary Study Endpoints: Objective response rate (ORR), disease control rate (DCR), duration of response (DoR), progression-free survival (PFS), overall survival (OS), safety and tolerability (according to CTCAE 5.0 criteria).

Exploratory Endpoints: Analysis of the correlation between PD-L1 expression and CTLA-4 expression in tumor tissues and the anti-tumor activity of Iparomlimab and Tuvonralimab Injection, and the correlation between EBV-DNA quantification and prognosis.

Statistical Analysis Methods: The chi-square test will be used for comparing rates. Time-event data will be used to estimate the survival function by the Kaplan-Meier method, draw survival curves, and estimate the median time and its 95% confidence interval.

What is being measured

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

  1. 3-year distant metastasis-free survival (DMFS) as assessed by imaging examinations (including CT, MRI, PET-CT) and clinical evaluations to determine the time from randomization to the first occurrence of distant metastasis or death from any cause

    DMFS will be calculated as the time from the date of enrollment to the date of first documented distant metastasis (confirmed by imaging modalities such as CT, MRI, or PET-CT) or death from any cause, whichever occurs earlier. Patients who are lost to follow-up or withdraw from the study will be censored at the last date they were known to be free of distant metastasis and alive. The 3-year DMFS rate will be estimated using the Kaplan-Meier method, with the 95% confidence interval reported.

    Measured: Up to 3 years after enrollment (each follow-up cycle is 3 months for the first two years, 6 months for the third year)

  2. Objective response rate (ORR) of the tumor as assessed by RECIST 1.1 criteria, including complete response (CR) and partial response (PR) confirmed by imaging examinations (CT, MRI)

    ORR is defined as the proportion of participants with best overall response of complete response (CR) or partial response (PR) according to RECIST 1.1. CR is defined as the disappearance of all target lesions and no new lesions, with normalization of tumor marker levels if applicable. PR is defined as at least a 30% decrease in the sum of the longest diameters of target lesions, taking as reference the baseline sum of longest diameters. Responses must be confirmed by a subsequent assessment at least 4 weeks after the initial documentation of CR or PR

    Measured: Every 9 weeks during treatment (each treatment cycle is 3 weeks) and at the end of treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Iparomlimab and Tuvonralimab Injection in people with Locally Advanced Nasopharyngeal Squamous Cell Carcinoma, run by Second Affiliated Hospital of Nanchang University.

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 21 inclusion and 27 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: opening soon, as of the sponsor's last update on 22 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

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?

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?

3-year distant metastasis-free survival (DMFS) as assessed by imaging examinations (including CT, MRI, PET-CT) and clinical evaluations to determine the time from randomization to the first occurrence of distant metastasis or death from any cause (time frame: Up to 3 years after enrollment (each follow-up cycle is 3 months for the first two years, 6 months for the third year)). 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 NCT07135804.

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 Aug 2025.
