What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
2% chlorhexidineDrug
Topical 2% chlorhexidine spray
Sterile Water as controlDrug
Topical sterile water spray with identical appearance and administration schedule, plus the same standard skin care and health education.
| Study group | Role | What they receive |
|---|---|---|
| Experimental intervention | Experimental | Topical 2% chlorhexidine spray once daily after showering, sprayed evenly over the entire radiation field from a distance of 15-20 cm, starting 1 day before radiotherapy and continuing until 1 week after radiotherapy; stopped when grade ≥2 acute radiation dermatitis occurs. Standard skin care and health education will also be provided. Receives: Drug: 2% chlorhexidine |
| Control intervention | Placebo comparator | Topical sterile water spray with identical appearance and administration schedule, plus the same standard skin care and health education. Receives: Drug: Sterile Water as control |

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing 2% chlorhexidine in people with Nasopharangeal Cancer, run by Jiangxi Provincial Cancer Hospital 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 2 inclusion and 2 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: looking for participants now, as of the sponsor's last update on 30 Apr 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 Tianzhu Lu, PhD (+8615270186250, lutianzhu2008@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Grade 2 acute radiation dermatitis with moist desquamation (grade 2-MD) or higher acute radiation dermatitis (time frame: Proportion of participants who develop CTCAE v5.0 grade 2-MD or higher grade 2 ARD during radiotherapy through 1 week after radiotherapy). 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 30 Apr 2026; AzTrials last refreshed its copy on 8 Nov 2026.
