About this study
Official title: Effectiveness of Topical Magnetite Zinc Oxide Composite Nanoparticles in the Management of Oral Potentially Malignant Lesions (A Randomized Controlled Clinical Trial)
ZnO nanoparticles are now being widely researched for their anticancer properties. They show relatively high biocompatibility. They also show selective cytotoxicity against cancerous cells in in vitro condition compared with other nanoparticles. They can be further surface engineered to show increased selective cytotoxicity. The synthesis process of ZnO nanoparticles is relatively easy, with a wide variety of methods. Owing to these different methods of synthesis, their size and size distribution can be easily controlled. One of the novel methods of synthesis of ZnO is Magnetite ZnO-Fe3O4 Composite Nanoparticles.Magnetite ZnO-Fe3O4 conjugated NPs retained inherent selective property of ZnO and magnetic property of Fe3O4 NPs and showed preferential cytotoxicity towards breast cancer cell line MDA-MB-231, with no significant cytotoxicity towards noncancerous Mouse Fibroblast NIH 3T3 cell.
Read the detailed description
Two interventions will be used; Magnetite ZnO-Fe3O4 Composite NPs extract and Placebo gel in custom made inert hydrophilic adhesive gel paste will be prepared in Nanotechnology engineering service in Egypt (Nano Gate), to enhance the adhesiveness of the two study interventions to oral mucosa.Group I (Test Group): Will include 15 patients with OPLs that will be treated with 5% topical ZnO-Fe3O4 Magnetic Composite NPs gel applied 3 times per day33 for 6 weeks9.
Group II (Positive Control Group):
Will include 15 patients with oral lichen planus lesions that will be treated with Topical Placebo Gel applied 3 times per day for 6 weeks.
The whole study period will be 18 weeks; 6 weeks as an active treatment period starting 1 week after the biopsy is taken then treatment discontinued for all groups and patients will be followed up for another 12 weeks in a treatment-free period.IV-Treatment efficacy evaluation A) Clinical efficacy assessment The assessment will be carried out at 0, 6 weeks and 18 weeks after starting the treatment protocol.
1-Imaging of the oral marker lesion Standardized photographs of the oral marker lesion for each patient will be taken with the same digital camera and setting, the surface area of the lesion will be outlined and measured using specific image software.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Magnetite ZnO Composite Nanoparticles in people with Oral Potentially Malignant Lesions, run by Ain Shams University at 1 site in Egypt.
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 3 inclusion and 7 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: finished, as of the sponsor's last update on 7 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 Egypt. 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 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Change in the clinical size in Low to Moderate Dysplastic OPLs using Magnetite ZnO-Fe3O4 Composite NPs using standardized photographs of the oral marker lesion for each patient (time frame: 6 weeks). 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 7 Apr 2026.
