About this study
Official title: NEO-SPACE Trial: Neoadjuvant Pembrolizumab-Gemcitabine-Cisplatin Followed by Concurrent Pembrolizumab-Chemoradiation and Maintenance Pembrolizumab for Stage IVA Nasopharyngeal Cancer
This is an open label, single arm, non-randomized, multi-site, phase 2 clinical trial of neoadjuvant pembrolizumab in combination with gemcitabine-cisplatin for 2 cycles,followed by concurrent pembrolizumab-cisplain-radiation, and then maintainence pembrolizumab monotherpy given every 3 weeks for a total treatment duration of 12 months, in previously untreated stage IVA ( UICC 8 th Edition ) nasopharyngeal cancer(NPC).
Read the detailed description
Nasopharyngeal cancer (NPC) is a predominantly Asian disease, with approximately 80% of the world's 86000 cases occurring in Asian countries (12). With advances in radiation technology such as intensity modulation radiotherapy (IMRT), local and nodal control exceeds 85-90% in most reported series. Distant metastasis remains the main mode of failure, particularly in locally advanced NPC. As an example, in a study by Pan et al (13), 5 years local and nodal control of 86% and 89% was achieved with concurrent chemo-IMRT respectively, but distant failure free survival of 77% and 72% was reported for patients with T4 and N3 disease respectively (AJCC 8th edition).
Current strategies to reduce distant metastasis, including the use of adjuvant chemotherapy have been inconclusive. One major disadvantage of adjuvant chemotherapy following the completion of chemoradiation is that approximately half of patients are unable to complete the full 3 cycles of adjuvant chemotherapy, due to treatment related toxicities. The use of induction chemotherapy has two potential benefits: the first is to downsize the tumour, making radiotherapy more tolerable; the second, it allows for patients to be able to complete the chemotherapy before the onset of chemoradiation associated toxicities.
There are at least two studies now supporting the use of induction chemotherapy. A recent publication by Ma et al (14), showed the addition of induction docetaxel, cisplatin and fluorouracil prior to concurrent chemoradiation resulted in 8% improvement (80% vs 72%) in 3-year failure-free survival. Similarly, Cao et al showed that 2 cycles of cisplatin and fluorouracil prior to chemoradiation improved the 3 years disease free survival in patients (15).
Gemcitabine and cisplatin has been shown to be more effective than 5-FU plus cisplatin as first-line treatment for recurrent or metastatic nasopharyngeal carcinoma (16). There are currently no studies looking at the addition of anti-PD-1 monoclonal antibody such as pembrolizumab either in the in the induction or maintenance setting. Hence, we are proposing the use of pembrolizumab in combination with 2 cycles of gemcitabine and cisplatin chemotherapy followed by concurrent chemoradiation. Following completion of chemoradiation, patients will receive maintenance pembrolizumab for total treatment duration of one year. The main objective of this Phase II study is to test the safety, efficacy and tolerability of this combination in the setting of locally advanced NPC (limited to T4 or N3, stage IVA by UICC 8th edition), as this group has the greatest risk of recurrence after the current standard treatment.
Preliminary evidence supporting the clinical efficacy of pembrolizumab monotherapy in NPC came from the KEYNOTE-028 trial, which was a global, nonrandomized, multi-cohort, phase Ib trial of pembrolizumab in patients with PD-L1-positive advanced solid tumors (17). Key eligibility criteria for the NPC cohort included unresectable or metastatic disease, failure on prior standard therapy, and PD-L1 expression in 1% or more of tumor cells or tumor-infiltrating lymphocytes. Patients received pembrolizumab 10 mg/kg every 2 weeks up to 2 years or until disease progression or unacceptable toxicity. In the initial report, twenty-seven NPC patients was evaluated. Median age was 52.0 years (range, 18 to 68 years); 92.6% received prior therapies for recurrent or metastatic NPC; 70.4% had received three or more therapies. Partial response and stable disease were observed in seven and 14 patients, respectively, for an ORR of 25.9% (95% CI, 11.1 to 46.3) over a median follow-up of 20 months. Drug-related adverse events that occurred in 15% or more of patients included rash (25.9%), pruritus (25.9%), pain (22.2%), hypothyroidism (18.5%), and fatigue (18.5%). Grade ≥ 3 drug-related adverse events occurred in eight patients (29.6%), and there was one drug-related death (sepsis). It was concluded that pembrolizumab demonstrated antitumor activity and a manageable safety profile in patients with recurrent or metastatic NPC.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Pembrolizumab in people with NPC, run by Chinese University of Hong Kong at 2 sites in 2 countries.
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 15 inclusion and 20 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: under way, not looking for participants, as of the sponsor's last update on 24 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Hong Kong, Singapore. 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?
Yes. Results are posted in the registry (first posted 24 Dec 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Two-year Progression Free Survival (time frame: 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 24 Dec 2025.
