About this study

Official title: Efficacy and Safety of Scipibaimab Combined With Tislelizumab in the Treatment of Patients With Recurrent and Metastatic Nasopharyngeal Carcinoma Who Have Failed First-line Treatment: a Multicenter, Single-arm, Non-randomized, Open-label Phase II Clinical Study

This study aims to explore the efficacy and safety of scipibaimab combined with tislelizumab in patients with recurrent or metastatic nasopharyngeal carcinoma who have progressed after first-line therapy.

Read the detailed description

In the immunotherapy era, patients with recurrent/metastatic nasopharyngeal carcinoma who progress after both platinum-based chemotherapy and PD-1 blockade lack further standard options. IL-4Rα inhibition can overcome PD-1 resistance by re-activating CD8+ T cells; combining scipibaimab (anti-IL-4Rα) with tislelizumab (anti-PD-1) has shown additive activity without overlapping toxicity. This trial will assess the efficacy and safety of the combination in patients who have failed prior platinum and PD-1 therapy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TislelizumabDrug

    Anti-PD-1 targeted immunotherapy

  • ScipibaimabDrug

    Scipibaimab (CM310) is a humanized IgG4 monoclonal antibody that selectively binds to a unique epitope on human IL-4Rα, thereby simultaneously blocking IL-4 and IL-13 signaling without competing with dupilumab's binding site; it exhibits cross-species reactivity (human, cynomolgus monkey, rat), displays linear pharmacokinetics with an estimated terminal half-life of ~300 h in monkeys, and has shown favorable safety and dose-proportional exposure in multiple Phase 1-3 trials for type-2 inflammatory diseases .

Scipibaimab combined with TislelizumabExperimentalPatients with recurrent or metastatic nasopharyngeal carcinoma who have progressed after first-line platinum-based chemotherapy plus PD-1 inhibition will receive scipibaimab 300 mg subcutaneous and tislelizumab 200 mg intravenous every 3 weeks until disease progression, unacceptable toxicity, or completion of 2-year treatment window.

    Measured: 2 years

  2. Duration of response

    Defined from date of first confirmed CR or a PR to date of first documentation of progression or death due to any cause, as determined by the investigator using Response Evaluation Criteria in Solid Tumors (RECIST1.1) from the National Cancer Institute (NCI).

    Measured: 2 years

  3. Progression-free survival rate

    Defined from date of registration to date of first documentation of progression or death due to any cause.

    Measured: 2 years

  4. Overall survival rate

    Defined from date of registration to date of first documentation of death from any cause or censored at the date of the last follow-up.

    Measured: 2 years

  5. Incidence rate of adverse events (AEs)

    Analysis of acute and late adverse events (AEs) are evaluated. Numbers of patients of treatment-related adverse events (acute toxicity) as assessed by CTCAE v5.0.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Tislelizumab and Scipibaimab in people with Nasopharyngeal Carcinoma (NPC), 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 10 inclusion and 19 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 5 Feb 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 Haiqiang Mai (86-20-87343380, maihq@sysucc.org.cn), 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: 2 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 NCT07388758, which also lists 5 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 5 Feb 2026; AzTrials last refreshed its copy on 8 Nov 2026.
