The Application of mRNA Immunotherapy Technology in Refractory Malignancies Associated With Epstein-Barr Virus (EBV)
40 participantsStarted 2025-08-01
Plain-language summary
Epstein-Barr virus (EBV) is an important tumor-associated virus. In 1997, the World Health Organization (WHO) officially classified EBV as a Group 1 carcinogen, as it is implicated in the pathogenesis of various epithelial malignancies and multiple types of lymphomas. Epithelial malignancies associated with EBV infection include nasopharyngeal carcinoma (NPC), gastric cancer, colorectal cancer, breast cancer, cervical cancer, prostate cancer, and oral cancer, among others. Currently, optimal therapeutic strategies for EBV-associated tumors remain lacking, particularly in patients with recurrent, metastatic, or refractory disease. Furthermore, although EBV infection plays a significant role in the development and progression of EBV-positive tumors and may influence patient prognosis, there are currently no precision therapeutic approaches specifically targeting EBV-positive lymphomas. Thus, treatment options for this patient population warrant further attention.
EBV mRNA vaccine is a therapeutic vaccine based on messenger RNA (mRNA) targeting antigens related to EBV. This clinical trial aims to evaluate the safety, tolerability, immunogenicity, and preliminary antitumor activity of EBV mRNA vaccine in patients with advanced EBV-positive malignant tumors, thereby providing a scientific basis for subsequent clinical development.

Inclusion Criteria:
Phase 1: Monotherapy Study of mRNA Vaccine
* Male or female patients aged ≥18 years;
* Patients with advanced Epstein-Barr virus (EBV)-positive tumors (e.g., nasopharyngeal carcinoma, NK/T-cell lymphoma, or gastric cancer) who have failed at least two lines of standard therapy;

Phase 2: Combination Therapy Study of mRNA Vaccine
* Male or female patients aged ≥18 years at screening;
* Histopathologically confirmed recurrent or metastatic nasopharyngeal carcinoma (NPC) not amenable to local therapy, with documented failure of at least one prior platinum-containing chemotherapy regimen and PD-1/L1 immunotherapy;

* Additional inclusion criteria may be supplemented.
Exclusion Criteria:
Phase 1: Monotherapy Study of mRNA Vaccine
* Participation in another clinical drug trial within the past 4 weeks;
* History of other malignancies, unless it is cervical carcinoma in situ, treated cutaneous squamous cell carcinoma or urothelial tumors, or other malignancies that have undergone curative treatment (at least 5 years prior to enrollment);
* Uncontrolled cardiac symptoms …
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
