NCT02008773

Brief Summary

The primary aim of the study is to determine the efficacy of adjunctive valacyclovir, in comparison to placebo, to improve visual (Brief Visuospatial Memory Test) and working (composite score of the Spatial Span and Letter Number Span tests) memory in individuals who are HSV-1 positive and early in the course of schizophrenia. We hypothesize that individuals who are HSV-1 positive, but not those who are HSV-1 negative, will demonstrate significant valacyclovir efficacy for visual and working memory.

Outcome Measures

Primary Outcomes (2)

  • Visual Memory

    To determine the efficacy of adjunctive valacyclovir, in comparison to placebo, to improve visual memory (Brief Visuospatial Memory Test) in individuals who are HSV-1 positive and early in the course of schizophrenia. The Brief Visuospatial Memory Test is a subscale of the MATRICS Consensus Cognitive Battery (MCCB) and was used to assess visual memory. The BVMT consists of three trials in which participants must recall shapes by drawing figures on a blank page after being given the opportunity to memorize the figures for 10 seconds. Each page consists of six figures. Points are awarded based on the accuracy of the drawn figure and by correct placement on the page. A minimum of 0 to 12 points are awarded per trial, so a participant can score between 0 and 36 points for all three trials. The raw score is then converted to a t-score, normed by age and sex. The min and max t-scores are between 0-100, a higher t-score representing a better outcome.

    Baseline, 8 weeks, and 16 weeks

  • Working Memory

    Determine the efficacy of adjunctive valacyclovir, in comparison to placebo, on working memory (composite score of the Wechsler Memory Scale-III: Spatial Span and Letter Number Span tests). WMS has 2 sections in which a subject recalls increasingly difficult sequences. The total raw score range for both sections is 0-32. The raw score is then converted to a tscore based on normative ranges by age and sex, ranging from 0-100. For both the raw and tscore a higher score reflects better performance. LNS consists of 24 increasingly difficult sequences of letters and numbers that a subject is to recall and repeat back in Numeric-Alpha sequential order. The total raw score range is 0-24. The raw score is then converted to a tscore based on normative ranges by age and sex, ranging from 0-100. For both the raw and tscore a higher score reflects better performance. The Working Memory composite score is calculated by summing the WMS and LNS tscores, a higher tscore reflects better performance.

    Baseline, 8 weeks, and 16 weeks

  • Clinically significant electrocardiogram (ECG) abnormality prior to randomization as defined by: participants with a corrected QT interval (Bazett's; QTcB) \>450 msec (male) or \>470 msec (female) prior to randomization. Repeat ECGs will be conducted at the discretion of the principal investigator or medical designee.
