IMPORTANCE/UNASSIGNED:High-quality evidence regarding suppressive valacyclovir treatment in herpes zoster ophthalmicus (HZO) is necessary to guide care. OBJECTIVE/UNASSIGNED:To determine whether suppressive valacyclovir compared with placebo delays the occurrence of new or worsening stromal keratitis (SK), endothelial keratitis (EK), iritis, or dendriform epithelial keratitis (DEK) during 12 months of treatment and if treatment benefit persisted at 18 months (secondary end point). DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:The Zoster Eye Disease Study (ZEDS) was a randomized clinical trial conducted in 95 sites from November 2017 to June 2024. Immunocompetent, nonpregnant adults with a history of an HZO rash, documented active keratitis or iritis within 1 year, and an estimated glomerular filtration rate of 45 mL/min/1.73 m2 or greater were eligible. After determined to be eligible, participants were randomized in 4 strata: age at onset (<60 years vs ≥60 years) and disease duration (<6 months vs ≥6 months). INTERVENTIONS/UNASSIGNED:A total of 12 months of double-masked daily valacyclovir, 1000 mg, or placebo. MAIN OUTCOMES AND MEASURES/UNASSIGNED:The primary outcome was time to first occurrence within 12 months of new or worsening SK, EK, iritis, or DEK. RESULTS/UNASSIGNED:A total of 527 participants (median [IQR] age, 60 [50-68] years; 266 female [50.5%]; 266 in the valacyclovir group; 261 in the placebo group) were randomized in 4 strata; 481 completed 12 months, and 460 completed 18 months. Data were analyzed by intention to treat. At 12 months, primary end points occurred in 86 participants (33%) assigned to placebo and 74 (28%) assigned to valacyclovir, and at 18 months in 104 participants (40%) assigned to placebo and 86 (32%) assigned to valacyclovir. The hazard ratio (HR) of the primary end point at 12 months was 0.77 for participants taking valacyclovir vs placebo (HR, 0.77; adjusted 95% CI, 0.56-1.05; P = .09) and 0.73 at the secondary end point at 18 months (HR, 0.73; adjusted 95% CI, 0.55-0.97; P = .03). There was a reduction of multiple other secondary end points at 12 months (HR, 0.70; 95% CI, 0.52-0.95; P = .02) and 18 months (HR, 0.72; 95% CI, 0.55-0.95; P = .02). CONCLUSIONS AND RELEVANCE/UNASSIGNED:Although the primary outcome did not show a benefit of suppressive valacyclovir treatment, secondary study outcomes showed treatment superiority at the 18-month end point and reduced number of multiple episodes of keratitis or iritis at both 12 and 18 months. These results support consideration of 1 year of suppressive valacyclovir treatment for HZO. TRIAL REGISTRATION/UNASSIGNED:ClinicalTrials.gov Identifier: NCT03134196.

IMPORTANCE/UNASSIGNED:Evidence regarding suppressive valacyclovir treatment on postherpetic neuralgia is necessary to guide care. OBJECTIVE/UNASSIGNED:To test the hypothesis that suppressive treatment with 1000 mg/d of oral valacyclovir for 12 months reduces the prevalence, severity, and duration of postherpetic neuralgia compared with placebo at 12 and 18 months in participants with herpes zoster ophthalmicus (HZO). DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:Multicenter, placebo-controlled randomized clinical trial including 527 immunocompetent, nonpregnant adults with history of HZO rash, documented keratitis, or iritis within 1 year and an estimated glomerular filtration rate of 45 mL/min/1.73 m2 or greater. The study was conducted at 95 participating sites (in Canada, New Zealand, and the US) from November 2017 to June 2024 and participant visits occurred every 3 months. INTERVENTION/UNASSIGNED:Treatment with 1000 mg/d of valacyclovir or placebo for 12 months. MAIN OUTCOMES AND MEASURES/UNASSIGNED:Prevalence of postherpetic neuralgia, severity as determined by pain score (a score of ≥3 on a scale of 1-10), pain duration (≥3 months after HZO onset), and total daily dose of pain medication. RESULTS/UNASSIGNED:Of the 527 participants (490 completed 12 months of treatment and 460 completed 18 months), 73 (14%) had postherpetic neuralgia and were analyzed by age at HZO onset (<60 years or ≥60 years) and disease duration (recent [<6 months] or chronic [≥6 months]). Of the 73 participants with postherpetic neuralgia (34 in the valacyclovir group and 39 in the placebo group), the mean age was 62.4 years (SD, 13.6 years), 59% were female, 5% were Black or African American, and 10% were Hispanic. The prevalence of postherpetic neuralgia at 12 months was not reduced by valacyclovir (12/32 [38%]) compared with placebo (14/35 [40%]) (between-group difference, 2.5% [95% CI, -20.8% to 25.8%]; P>.99). The participants who were younger than 60 years at HZO onset and had a chronic disease duration had lower pain scores in the valacyclovir group (mean score, 0.3 [SD, 0.9]) vs the placebo group (mean score, 0.8 [SD, 1.9]) at 12 months (P = .045) and at 18 months (mean score, 0.2 [SD, 0.9] vs 1.0 [SD, 2.3], respectively; P = .02). There was a decrease in pain duration in the valacyclovir group at 18 months (mean, 13.6 [SD, 11.4] months) vs the placebo group (mean, 18.7 [SD, 29.5] months) (linear mixed-effects model between-group difference, -3.39 months [95% CI, -6.73 to -0.04 months]; P = .046). The total daily dose of neuropathic pain medication was lower in the valacyclovir group (mean, 271.4 [SD, 593.8] mg/d) vs the placebo group (mean, 363.4 [SD, 592.2] mg/d) at 12 months (linear mixed-effects model P = .006) and at 18 months (mean, 209.0 [SD, 412.8] mg/d vs 286.2 [SD, 577.9] mg/d, respectively; linear mixed-effects model P = .01). CONCLUSIONS AND RELEVANCE/UNASSIGNED:One year of suppressive treatment with valacyclovir was associated with a lower dosage of neuropathic pain medication. Participants in the valacyclovir group, who were younger at HZO onset and had a chronic disease duration, had lower pain scores. These secondary outcomes support consideration of 1 year of suppressive treatment with valacyclovir to reduce dosage of pain medications and pain due to HZO.

PURPOSE/OBJECTIVE:For accelerated 3-year MD (3YMD) pathways to be fully adopted in medical education, a comprehensive analysis of outcome data is needed. This study includes 7 accelerated 3YMD graduating classes at NYU Grossman School of Medicine (NYUGSOM) and reports on outcomes from both medical school and internship compared to their 4-year MD (4YMD) counterparts. METHOD/METHODS:Outcomes across the undergraduate-graduate medical education continuum for the first 7 classes of NYUGSOM graduates (matriculated from 2013-2019) from the accelerated 3YMD (n = 136) and 4YMD pathways (n = 681) were compared. For the internship outcomes, 3YMD interns were compared with 4YMD interns who graduated from NYUGSOM and all 4YMD interns (4YMD graduates from NYUGSOM and any other medical school) at NYUGSOM residencies. RESULTS:Accelerated 3YMD students were approximately 5 months older at admission and had higher multiple mini-interview scores than 4YMD students. Overall, accelerated 3YMD students performed similarly to 4YMD students during medical school and internship. Significant differences included higher performance by 3YMD students on preclerkship exams and lower performance on Steps 1 and 2 (average: 5.6 and 8.3 fewer points, respectively) and the physical examination portion of the NYUGSOM Comprehensive Clinical Skills Exam. Internship data indicated comparable team assessments across all residencies, statistically significant higher performance on Step 3 when compared to all 4YMD interns, and, in internal medicine, comparable clinical reasoning between 3YMD and all 4YMD interns. When comparing 3YMD interns to all 4YMD interns in the internal medicine residency program, 3YMD interns had a statistically significantly higher performance on milestones. CONCLUSIONS:The outcomes from 7 years of graduating accelerated 3YMD students at NYUGSOM show similar performance in medical school and early residency to 4YMD graduates. Long-term study of accelerated 3YMD students from NYUGSOM and other medical schools is needed to further validate the success of this innovative medical education pathway.

In the last decade, there has been tremendous growth in the number of accelerated three-year medical pathway programs. The needs of accelerated pathway students are different from traditional students, and a robust mentoring program should be developed to address specific issues and guarantee student success. We describe a unique approach to the development of a mentoring program for accelerated three-year MD students at New York University Grossman School of Medicine.

PURPOSE/OBJECTIVE:The aim of this study was to identify successful recruitment strategies and obstacles reported by principal investigators (PIs) of the Zoster Eye Disease Study (ZEDS). METHODS:A web-based survey was created by a subset of ZEDS PIs and distributed to ZEDS PIs after study enrollment was closed. The survey queried investigators about recruitment strategies and obstacles, use of prophylactic oral antiviral medication, electronic medical records, telemedicine, COVID-19 effect, turnover of research staff, and recruitment outreach to minority and underserved populations. The survey allowed objective measures and free-text options. Analysis from centers with higher enrollment was compared with centers with lower enrollment to identify successful strategies and common obstacles. RESULTS:The most frequently cited helpful strategies were participation from ophthalmologists within the PI's institution (33/63, 52%), ophthalmology resident referrals (23/63, 37%), and chart review (23/63, 37%). Travel to participating clinical center (42/63, 67%) and ongoing prophylactic use of oral systemic antiviral medication (39/63, 62%) were common obstacles. Research coordinator turnover was identified as a contributor to reduced recruitment success by 49% (31/63) of PIs and made recruitment much harder for 22% (14/63). A small number of investigators used telemedicine (18/63, 29%) and few made efforts to recruit from minority and underserved populations (10/63, 16%). CONCLUSIONS:Our survey highlights the importance of internal ophthalmologist referral, chart review, and research coordinator commitment for successful clinical trial recruitment. We discuss the impact of prophylactic use of oral antiviral medication on recruitment. Future randomized clinical trials should mobilize the helpful recruitment strategies and improve outreach to underserved populations.

PURPOSE/OBJECTIVE:The Zoster Eye Disease Study (ZEDS) is the first randomized clinical trial to study the efficacy of long-term (1 year) suppressive valacyclovir treatment on herpes zoster ophthalmicus (HZO) outcomes. This article details the baseline characteristics of participants. SETTING/METHODS:The study was set at 95 participating clinical centers in 33 states, Canada, and New Zealand. STUDY POPULATION/METHODS:Immunocompetent adults with a history of a characteristic HZO unilateral rash and documentation of an episode of active dendriform epithelial keratitis, stromal keratitis, endothelial keratitis, or iritis within the preceding year, enrolled in ZEDS from November 2017 to January 2023. INTERVENTION/METHODS:Participants were randomized to double-masked oral valacyclovir 1 gm daily versus placebo for 1 year of treatment and followed for 18 months. RESULTS:Five hundred twenty-seven participants were enrolled across 4 strata according to age at HZO onset (younger or older than 60 years) and duration of HZO at enrollment (less or greater than 6 months), with an even distribution of men and women and a median age of 60 years. More participants with recent (57%, 300/527) than chronic HZO and younger than 60 years at HZO onset (54%, 286/527) were enrolled. Most participants were treated acutely with a recommended antiviral regimen (91%, 480/527) and had not been vaccinated against zoster (79%, 418/527). CONCLUSIONS:The broad ZEDS study population enhances the likelihood that ZEDS will provide generalizable high-quality evidence regarding the efficacy and safety of suppressive valacyclovir for HZO immunocompetent adults and whether it should become standard of care.

PURPOSE/OBJECTIVE:The Zoster Eye Disease Study (ZEDS) is a multicenter randomized clinical trial (RCT) funded by the National Eye Institute aiming to determine the efficacy of suppressive valacyclovir treatment in herpes zoster ophthalmicus (HZO) that enrolled fewer participants than planned (527/780, 67.6%). Understanding reasons for nonparticipation of likely eligible prescreened patients provides insights into patient populations that are not represented by ZEDS and barriers in clinical trials. METHODS:In this retrospective cohort study, HZO adults likely eligible for ZEDS with a history of a typical rash and a medical record within the past year of an episode of epithelial or stromal keratitis or iritis were prescreened at activated Participating Clinical Centers from 2017 to 2022 using a standard prescreening log. De-identified data including demographic information, reasons for exclusion because of ineligibility, and patient refusal were retrospectively entered into REDCap and analyzed. RESULTS:Prescreening logs with reasons for nonconsent (1244/1706, 72.9%) were included in the data set. Patients were excluded from the study (915/1244, 73.6%) because they did not meet all inclusion criteria (619/915, 67.7%) or met an exclusion criterion (296/915, 32.3%). Among the 12 exclusion criteria for the ZEDS study, immunocompromise (76/296, 25.7%) and renal insufficiency (50/296, 16.9%) were most frequently reported. Patient refusal to participate (327/1,244, 26.3%) was common. CONCLUSION/CONCLUSIONS:The most common reasons for ineligibility were immunocompromise and renal insufficiency. There may be benefits to long-term antiviral use in these populations not captured in ZEDS. A quarter (26.3%) of prescreened patients refused participation, showing the substantial impact of patient preferences on trial participation.

Purpose/UNASSIGNED:Herpes zoster (HZ) has been identified as a potential association with the BNT162b2 COVID-19 vaccination. This study evaluated this possible association in a cohort of patients receiving the vaccination. Methods/UNASSIGNED:Epic electronic health records of adult patients who received at least one COVID-19 vaccination between January 12, 2020 and 9/30/2021 within the NYU Langone Health were reviewed to analyze a new diagnosis of herpes zoster within 3 months before compared to 3 months after vaccination. Results/UNASSIGNED:Of the 596,111 patients who received at least one COVID-19 vaccination, 716 patients were diagnosed with HZ within three months prior to vaccination, compared to 781 patients diagnosed within 3 months afterwards. Using the chi-square test for independence of proportions, there was not a statistically significant difference in frequency of HZ before (proportion: 0.0012, 95% CI: [0.0011, 0.0013]) vs. after vaccination (proportion: 0.0013, 95% CI: [0.0012, 0.0014]); (p = 0.093). Conclusions and importance/UNASSIGNED:This study did not find evidence of an association between COVID-19 vaccination and a new diagnosis of HZ. We encourage health care professionals to strongly recommend COVID-19 vaccinations per Centers for Disease Control (CDC) recommendations and vaccination against HZ according to Food and Drug Administration (FDA) approval for the recombinant zoster vaccine.

PURPOSE/OBJECTIVE:The purpose of this study was to describe the rationale and design of the Zoster Eye Disease Study (ZEDS). METHODS:ZEDS is a National Eye Institute-supported randomized clinical trial designed to determine whether 1 year of suppressive valacyclovir in patients with herpes zoster ophthalmicus (HZO) reduces complications because there is currently no high-quality evidence to support its use. Eligible patients are 18 years and older, immunocompetent, have a history of a typical rash at disease onset, and have had a record of active epithelial or stromal keratitis or iritis within 1 year before enrollment. Exclusion criteria include estimated glomerular filtration rate less than 45 or pregnancy. The primary endpoint is the time to first occurrence of new or worsening dendriform epithelial keratitis, stromal keratitis without or with ulceration, endothelial keratitis, or iritis due to HZO during 12 months of study treatment requiring prespecified treatment changes. The study has 80% power to detect a 30% difference between treatment groups, with a 30% rate of endpoints by 1 year assumed among controls. Secondary and exploratory questions include whether there is a persistent treatment benefit during the 6 months after treatment, whether development of postherpetic neuralgia varies by treatment group, and whether vaccinations against herpes zoster affect study outcomes and coronavirus disease 19 status. RESULTS:Over approximately 4 years, over 400 study participants have been enrolled. CONCLUSIONS:ZEDS aims to provide scientific evidence on whether suppressive valacyclovir treatment improves outcomes in HZO and should become the standard of care.
