About this study

Official title: Epstein-Barr Virus DNA to Systemic Therapy for Treatment Adaptation in High Risk Nasopharyngeal Carcinoma (EP-STAR Trial) A Phase II, Multi-center, Biomarker-guided, Umbrella Trial

The investigators aim to investigate whether incorporating on-treatment EBV DNA surveillance for monitoring tumor responses to treatment and for guiding individuliased treatment adaptation can improve prognosis in nasopharyngeal carcinoma patient . For patients with detectable EBV DNA after one cycle of IC, which then drops to undetectable levels during the following IC cycles (intermediate responders/intermediate relapse risk), the investigators aim to investigate whether additional adjuvant metronomic capecitabine would benefit this subgroup. For patients with detectable EBV DNA after three cycles of IC or with EBV DNA bounce during the induction phase (insensitive to IC/high relapse risk), the investigators aim to investigate whether concurrent administration of anti-PD-1 therapy during the following treatment phases (including concurrent phase and adjuvant phase) can benefit this subgroup.

Read the detailed description

Nasopharyngeal carcinoma (NPC) is a unique head and neck cancer characterized by an extremely unbalanced global distribution. The highest incidence is observed in endemic regions, such as southern China and Southeast Asia, with an age-standardized rate of 3.0 per 100,000 in China to 0.4 per 100,000 in Caucasian populations. The fast progress of modern imaging and the application of intensity-modulated radiotherapy (IMRT) has improved the local control rate significantly. Distant metastasis has become the major cause of treatment failure.

The 2018 National Comprehensive Cancer Network (NCCN) guideline recommends concurrent chemoradiotherapy (CCRT) ± induction chemotherapy (IC)/adjuvant chemotherapy (AC) as the standard treatment for stage II-IVa disease (category 2A). While it is worth noting that there is extensive heterogeneity among patients with NPC, and even among patients with the same disease stage, the risk of relapse varies. More importantly, patients can have differing sensitivity to RT and chemotherapy. The abovementioned reasons result in over-treatment in some patients with relatively low relapse risk; intensive treatments lead to unnecessary toxicities, and greatly affect quality of life (QoL). On the other hand, the current treatment strategy may be not optimal for patients with high relapse risk or who are not sensitive to traditional chemoradiotherapy. Therefore, there is an urgent need for identifying and applying promising biomarkers, real-time monitoring of patient responses to treatment, predicting relapse risk, and guiding real-time treatment adaptation for individualized therapy.

The investigators aim to investigate whether incorporating on-treatment EBV DNA surveillance for monitoring tumor responses to treatment and for guiding individuliased treatment adaptation can improve prognosis in nasopharyngeal carcinoma patient . For patients with detectable EBV DNA after one cycle of IC, which then drops to undetectable levels during the following IC cycles (intermediate responders/intermediate relapse risk), the investigators aim to investigate whether additional adjuvant metronomic capecitabine would benefit this subgroup. For patients with detectable EBV DNA after three cycles of IC or with EBV DNA bounce during the induction phase (insensitive to IC/high relapse risk), the investigators aim to investigate whether concurrent administration of anti-PD-1 therapy during the following treatment phases (including concurrent phase and adjuvant phase) can benefit this subgroup.

Study groups in NCT04072107
Study groupRoleWhat they receive
Arm IExperimentalPatients receive GP IC + IMRT concurrent with cisplatin chemotherapy + capecitabine AC. All patients will receive concurrent cisplatin (100 mg/m2) every 3 weeks, in a total of three cycles. All patients will receive low-dose metronomic capecitabine (650 mg/m2 bid, oral, d1-21, q3w) until disease progression, or intolerable toxicity or 6 months.
Receives: Drug: Capecitabine
Arm IIExperimentalPatients receive GP IC + IMRT concurrent with cisplatin chemotherapy and anti-PD-1 therapy (sintilimab) + anti-PD-1 therapy (sintilimab) AC. All patients will receive concurrent cisplatin (100 mg/m2) and sintilimab (200 mg, IV drop 30-60 min) every 3 weeks in a total of three cycles. All patients will receive adjuvant anti-PD-1 therapy (sintilimab, 200 mg, IV drop 30-60 min, q3w) in a total of nine cycles until disease progression, or intolerable toxicity or 6 months.
Receives: Drug: sintilimab

What is being measured

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

  1. Failure-free survival

    FFS will be measured from the day of enrollment until treatment failure, death from any cause, or the last follow-up visit, whichever occurred first.

    Measured: 2 year

Secondary outcomes (6)
  1. overall survival

    measured from the day of enrollment until death due to any cause, or the last follow-up visit.

    Measured: 2 year

  2. Distant metastasis failure-free survival

    measured from the day of enrollment until death until distant metastasis , or the last follow-up visit.

    Measured: 2 year

  3. Locoregional failure-free survival

    measured from the day of enrollment until death until local and/or regional recurrence, or the last follow-up visit.

    Measured: 2 year

  4. Adverse events

    The incidence of immune-related and other adverse events

    Measured: up to 5 years

  5. Patient reported quality-of-life score

    Patient reported quality of life would be evaluated using the Quality of Life Questionnaire-Core 30 module (QLQ-C30)

    Measured: up to 2 years

  6. Biomarker analysis

    Exploratory biomarker analysis that would be able to predict patient treatment benefits, for example PD-L1 expression, tumor mutational burden, etc.

    Measured: Through study completion

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 9 inclusion and 11 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: status not confirmed, as of the sponsor's last update on 18 Jun 2023. 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?

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?

Failure-free survival (time frame: 2 year). It is what the study was designed to measure, not a finding.
