About this study
Official title: Phase 1/2 Trial Integrating Allogeneic NK Cells in High-risk Advanced Stage III-IV Nasopharyngeal Cancer Patients
This clinical trial aims to determine whether Natural Killer (NK) cell therapy administered in combination with concurrent chemoradiotherapy (CRT) can reduce recurrence in patients with advanced nasopharyngeal cancer (NPC), and to identify the highest safe and tolerable dose of allogeneic NK cells. Allogeneic NK cells, derived from healthy donors, have demonstrated good tolerability in cancer patients.
The primary research questions are:
Read more
- What is the maximum tolerated dose (MTD) of allogeneic NK cells when administered with CRT in NPC patients?
- Can the addition of allogeneic NK cells to standard CRT reduce the proportion of NPC patients with detectable plasma EBV-DNA from 30% to 10%?
Phase 1: Participants will receive one of five escalating doses of allogeneic NK cells with CRT to determine the MTD.
Phase 2: Participants will receive the established MTD NK dose together with CRT.
Participants will undergo regular safety monitoring, side-effect assessment, measurement of plasma EBV-DNA levels, and surveillance for disease recurrence.
Read the detailed description
The investigator plans to enrol 31 newly diagnosed NPC patients with Stage III-IVA/B (T1-4, N1-3, M0) disease who are scheduled to receive standard-of-care treatment over an estimated 24-36-month period.
The clinical trial consists of a Phase 1 dose-escalation study followed by a single-arm Phase 2 study. In Phase 1, at least six participants will be treated at the MTD of allogeneic NK cells, after which an additional 25 participants are expected to be enrolled in Phase 2.
Phase 1 will use the Bayesian Model Averaging Continual Reassessment Method (BMA-CRM) to determine the MTD, evaluating five NK-cell dose levels of 0.5×10⁷, 0.8×10⁷, 1.1×10⁷, 1.4×10⁷, and 1.8×10⁷ cells/kg, with the starting dose set at 0.8×10⁷ cells/kg. Dose-limiting toxicity (DLT) is defined as Grade 3 to 5 toxicities per CTCAE criteria, and the target toxicity limit (TTL) is set at a maximum allowable DLT probability of 30%. Toxicity probability will be reassessed whenever a DLT occurs to determine whether it exceeds the TTL. If the cohort completes evaluation at a given dose level and the toxicity probability is within the TTL, dose escalation will proceed; however, if the toxicity probability exceeds the TTL, the dose will be rejected, and de-escalation will occur. When toxicity probability is low, accelerated escalation may be implemented.
Phase 1 will conclude once six participants have been treated at the designated MTD without developing Grade 3 to 5 toxicities; at that point, the MTD will be accepted. All participants in Phase 1 will receive standard NPC treatment combined with the NK-cell dose evaluated at the time of their enrollment.
Phase 2 is a single-arm study based on historical findings that approximately 25% to 30% of locally advanced NPC patients continue to exhibit detectable circulating EBV-DNA following standard CRT. The study hypothesizes that the addition of allogeneic NK cells will reduce this proportion to 10%.
All participants in Phase 2 will receive standard CRT along with NK-cell infusions administered once weekly during weeks 3, 6, 7, 8, 9, and 10. Interleukin-2 (200 IU/mL) will be co-administered with NK cells in Plasma-Lyte 148 supplemented with 2% human serum albumin (HSA). The primary endpoint of Phase 2 is the reduction in the proportion of patients with detectable post-treatment circulating EBV-DNA. At week 9, if the participants' circulating EBV-DNA levels have decreased but remain detectable, would be given an option for an additional four NK-cell infusions during weeks 12 to 15.
The secondary endpoint is the improvement in survival and recurrence rates within 24 to 36 months compared with historical cohorts receiving standard treatment alone. NK cells will be generated from healthy-donor PBMCs.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Allogenic expanded Natural Killer Cells (AlloNK1)Biological
The NK cells would be enriched and expanded ex vivo in a GMP facility from healthy donor PBMCs. Prior to administration, the NK cells would be formulated in an infusion medium based on the corresponding dose level that is required for each participant.
Participants will receive an intravenous infusion of NK cells during and after the standard CRT. Six doses are administered at weeks 3,6,7,8,9, and 10. In Phase 1, NK cell doses range from 0.5x10^7 to 1.8x10^7 cells/kg for the determination of the maximum tolerated dose (MTD). In phase 2, all participants will receive NK cells at the established MTD.
| Study group | Role | What they receive |
|---|---|---|
| Concurrent and adjuvant allogeneic NK cell therapy | Experimental | Participants will receive standard chemoradiotherapy for locally advanced nasopharyngeal carcinoma along with adjuvant therapy of NK cells. Nk cells would be enriched and expanded using PBMCs from healthy donors.
Phase 1 dose escalation study which uses 5 different dosages of 0.5 x 10^7, 0.8x10^7, 1.1x10^7, 1.4 x 10^7, and 1.8x10^7 to determine the Maximum tolerated dose (MTD). If the MTD is determined in phase 1, the study will enter phase 2, where the determined dose level will be used for participants. The participants will receive six intravenous NK cell infusions at weeks 3,6,7,8,9, and 10 during and after CRT. If the participant's EBV level is still detectable, they would be suggested for supplementary NK cell treatments for an additional four weeks.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This clinical trial aims to determine whether Natural Killer (NK) cell therapy administered in combination with concurrent chemoradiotherapy (CRT) can reduce recurrence in patients with advanced nasopharyngeal cancer (NPC), and to identify the highest safe and tolerable dose of allogeneic NK cells. Allogeneic NK cells, derived from healthy donors, have demonstrated good tolerability in cancer patients.
The primary research questions are:
- What is the maximum tolerated dose (MTD) of allogeneic NK cells when administered with CRT in NPC patients?
- Can the addition of allogeneic NK cells to standard CRT reduce the proportion of NPC patients with detectable plasma EBV-DNA from 30% to 10%?
Phase 1: Participants will receive one of five escalating doses of allogeneic NK cells with CRT to determine the MTD.
Phase 2: Participants will receive the established MTD NK dose together with CRT.
Participants will undergo regular safety monitoring, side-effect assessment, measurement of plasma EBV-DNA levels, and surveillance for disease recurrence.

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 combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
