About this study
Official title: A Randomized Double-blind Controlled Trial of Valacyclovir Add-on Treatment of HSV Positive Early Course Schizophrenia Patients
The purpose of this study is to examine whether antiviral medication will help improve psychotic symptoms and cognition in individuals early in the course of schizophrenia or schizoaffective disorder who are exposed to herpes simplex virus, type 1 (HSV 1), a virus that causes commonly occurring and recurrent cold sores.
Read the detailed description
The main objective of the study is to evaluate the efficacy of add-on treatment of Valacyclovir (VAV), an antiviral medication, in the treatment of early course schizophrenia/schizoaffective disorder patients. Our main hypothesis is that the VAV add-on treatment will improve positive, negative and cognitive symptoms in herpes simplex virus (HSV) positive schizophrenia or schizoaffective disorder patients. We hypothesize that the grey matter reductions in specific brain regions (such as prefrontal regions) will improve in patients on VAV + antipsychotic compared to those on placebo + antipsychotic and the improvements in positive, negative and cognitive symptoms will be correlated with the grey matter changes.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ValacyclovirDrug
1 g PO BID x 2 weeks after 2 weeks it goes up to 1.5 g PO BID x 16 weeks along with antipsychotic
PlaceboDrug
2 pills twice a day x 2 weeks, after 2 weeks 3 pills twice a day x 16 weeks along with antipsychotic
| Study group | Role | What they receive |
|---|---|---|
| Valacyclovir | Experimental | 1 gram pill taken twice a day for 2 weeks, after 2 weeks it increased to 1.5 gram pill taken twice a day for 16 weeks. Receives: Drug: Valacyclovir |
| Sugar pill | Placebo comparator | 2 placebo pills taken twice a day for 2 weeks, after 2 weeks 3 pills taken twice a day for 16 weeks. Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
PANSS Positive and Negative Syndrome Scale for Schizophrenia
This is a structured measure of severity of psychopathology that includes both positive and negative symptoms. The range is a minimum score of 30 and the maximum is 210. The lower scores suggest milder severity of illness domains.
Measured: Baseline, Weeks 2, 4, 6, 10, 14, 18
Cognitive Function Neuropsychological Battery (Gur Battery)
All results are given as the mean difference between an 18 week follow-up and the baseline battery administrations.This is a computerized test that measures both accuracy and response times. A range for response times is not available because of individual variabilities. Accuracy scores can vary for each test: Working memory accuracy range was 0-16. Verbal memory accuracy range was 0-20. For both, the higher the score the better. No cut offs are available
Measured: Baseline, Week 18
Secondary outcomes (1)
Changes in Grey Matter Deficit
Gray matter volume changes (in cc) were measured using structural MRI. Changes were reported as gray matter volume in cc. Note: Assessment of blood oxygenation level dependent (BOLD) changes using fMRI were erroneously included in the original study record.
Measured: Baseline, Week 18

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 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 9 May 2018). 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?

What does the primary outcome measure?
PANSS Positive and Negative Syndrome Scale for Schizophrenia (time frame: Baseline, Weeks 2, 4, 6, 10, 14, 18). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00514449, which also lists 2 linked publications.
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 14 Jun 2018.
