About this study
The proposed study will test the safety and efficacy of sodium valproate in the induction of Epstein-Barr virus (EBV) lytic cycle antigen expression in tumor tissue of patients undergoing primary therapy for nasopharyngeal carcinoma. Up to 20 patients will be given valproic acid for 2 weeks. The primary surrogate endpoint for efficacy will be expression of EBV lytic antigens by immunohistochemistry in tumor tissue. Biopsies of primary tumor will be taken after 2 weeks with achievement of a therapeutic concentration of valproate. Expression of immunodominant EBV latency antigens in tumor tissue, EBV viral load by real time PCR, and valproate levels will be measured. Adverse events associated with valproate in NPC patients will be described.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Up to 20 patients will be given valproic acid for 2 weeks. The primary surrogate endpoint for efficacy will be expression of EBV lytic antigens by immunohistochemistry in tumor tissue. Biopsies of primary tumor will be taken after 2 weeks with achievement of a therapeutic concentration of valproate. Expression of immunodominant EBV latency antigens in tumor tissue, EBV viral load by real time PCR, and valproate levels will be measured. Adverse events associated with valproate in NPC patients will be described.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing valproic acid in people with Nasopharyngeal Carcinoma, run by Johns Hopkins University at 1 site in Singapore.
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 9 inclusion and 11 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The record says: withdrawn, as of the sponsor's last update on 18 May 2020. 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 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 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.
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 was withdrawn before enrolling participants, so there are no results.
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?
expression of EBV lytic cycle antigens in NPC tumor tissue. (time frame: 2 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 18 May 2020.
