TL;DR: ChAMPION-NMOSD (NCT04201262) as mentioned in this paper is a phase 3, open-label, externally controlled interventional study evaluating the efficacy and safety of the terminal complement inhibitor ravulizumab in adult patients with anti-aquaporin-4 antibody-positive (AQP4+) neuromyelitis optica spectrum disorder.
Abstract: CHAMPION‐NMOSD (NCT04201262) is a phase 3, open‐label, externally controlled interventional study evaluating the efficacy and safety of the terminal complement inhibitor ravulizumab in adult patients with anti–aquaporin‐4 antibody–positive (AQP4+) neuromyelitis optica spectrum disorder (NMOSD). Ravulizumab binds the same complement component 5 epitope as the approved therapeutic eculizumab but has a longer half‐life, enabling an extended dosing interval (8 vs 2 weeks).

TL;DR: The inverse relationship between levels of these cells (particularly the CD20-expressing CD4+ and CD8+ T cells) in the circulation of MS patients, with active and impending CNS inflammation, suggests that these cells participate early on in the cellular immune responses involved in relapse development as discussed by the authors .
Abstract: Significance CD20-expressing CD4+ and CD8+ T cells harbor proinflammatory and central nervous system (CNS)-homing attributes. The inverse relationship between levels of these cells (particularly the CD20dimCD8+ T cells) in the circulation of MS patients, with active and impending CNS inflammation, suggests that these cells participate early on in the cellular immune responses involved in relapse development. The differential effects of anti-CD20 treatment on CD4+ and CD8+ T cell subsets point to different contributions of direct removal of CD20-expressing T cells, as well as indirect effects likely reflecting the removal of B cells that alters in vivo T cell:B cell interactions.

TL;DR: In this article , an evidence-based Delphi consensus process was used to develop validated statements for the management of aquaporin-4 immunoglobulin G (AQP4-IgG)-seropositive NMOSD.
Abstract: Background and Objectives Neuromyelitis optica spectrum disorder (NMOSD) is a rare debilitating autoimmune disease of the CNS. Three monoclonal antibodies were recently approved as maintenance therapies for aquaporin-4 immunoglobulin G (AQP4-IgG)–seropositive NMOSD (eculizumab, inebilizumab, and satralizumab), prompting the need to consider best practice therapeutic decision-making for this indication. Our objective was to develop validated statements for the management of AQP4-IgG–seropositive NMOSD, through an evidence-based Delphi consensus process, with a focus on recommendations for eculizumab, inebilizumab, and satralizumab. Methods We recruited an international panel of clinical experts in NMOSD and asked them to complete a questionnaire on NMOSD management. Panel members received a summary of evidence identified through a targeted literature review and provided free-text responses to the questionnaire based on both the data provided and their clinical experience. Responses were used to generate draft statements on NMOSD-related themes. Statements were voted on over a maximum of 3 rounds; participation in at least 1 of the first 2 rounds was mandatory. Panel members anonymously provided their level of agreement (6-point Likert scale) on each statement. Statements that failed to reach a predefined consensus threshold (≥67%) were revised based on feedback and then voted on in the next round. Final statements were those that met the consensus threshold (≥67%). Results The Delphi panel comprised 24 experts, who completed the Delphi process in November 2021 after 2 voting rounds. In round 1, 23/25 statements reached consensus and were accepted as final. The 2 statements that failed to reach consensus were revised. In round 2, both revised statements reached consensus. Twenty-five statements were agreed in total: 11 on initiation of or switching between eculizumab, inebilizumab, and satralizumab; 3 on monotherapy/combination therapy; 7 on safety and patient population considerations; 3 on biomarkers/patient-reported outcomes; and 1 on research gaps. Discussion An established consensus method was used to develop statements relevant to the management of AQP4-IgG–seropositive NMOSD. These international statements will be valuable for informing individualized therapeutic decision-making and could form the basis for standardized practice guidelines.
TL;DR: In this article , the authors investigated the effect of time to high-dose corticosteroid treatment on 6-month visual outcomes in acute optic neuritis (ON) presenting within 30 days of the inaugural ON.
Abstract: Optic neuritis (ON) often occurs at the presentation of multiple sclerosis (MS), neuromyelitis optica spectrum disorders (NMOSD), and myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease (MOGAD). The recommended treatment of high-dose corticosteroids for ON is based on a North American study population, which did not address treatment timing or antibody serostatus. The Acute Optic Neuritis Network (ACON) presents a global, prospective, observational study protocol primarily designed to investigate the effect of time to high-dose corticosteroid treatment on 6-month visual outcomes in ON. Patients presenting within 30 days of the inaugural ON will be enrolled. For the primary analysis, patients will subsequently be assigned into the MS-ON group, the aquapotin-4-IgG positive ON (AQP4-IgG+ON) group or the MOG-IgG positive ON (MOG-IgG+ON) group and then further sub-stratified according to the number of days from the onset of visual loss to high-dose corticosteroids (days-to-Rx). The primary outcome measure will be high-contrast best-corrected visual acuity (HC-BCVA) at 6 months. In addition, multimodal data will be collected in subjects with any ON (CIS-ON, MS-ON, AQP4-IgG+ON or MOG-IgG+ON, and seronegative non-MS-ON), excluding infectious and granulomatous ON. Secondary outcomes include low-contrast best-corrected visual acuity (LC-BCVA), optical coherence tomography (OCT), magnetic resonance imaging (MRI) measurements, serum and cerebrospinal fluid (CSF) biomarkers (AQP4-IgG and MOG-IgG levels, neurofilament, and glial fibrillary protein), and patient reported outcome measures (headache, visual function in daily routine, depression, and quality of life questionnaires) at presentation at 6-month and 12-month follow-up visits. Data will be collected from 28 academic hospitals from Africa, Asia, the Middle East, Europe, North America, South America, and Australia. Planned recruitment consists of 100 MS-ON, 50 AQP4-IgG+ON, and 50 MOG-IgG+ON. This prospective, multimodal data collection will assess the potential value of early high-dose corticosteroid treatment, investigate the interrelations between functional impairments and structural changes, and evaluate the diagnostic yield of laboratory biomarkers. This analysis has the ability to substantially improve treatment strategies and the accuracy of diagnostic stratification in acute demyelinating ON. Trial registration ClinicalTrials.gov, identifier: NCT05605951.
TL;DR: In this paper , the authors explored fluid and imaging biomarkers to better understand the mechanism of action of satralizumab and the neuronal and immunological changes following treatment in AQP4-IgG+ NMOSD.
Abstract: Background Neuromyelitis optica spectrum disorder (NMOSD) is a rare, autoimmune disease of the central nervous system that produces acute, unpredictable relapses causing cumulative neurological disability. Satralizumab, a humanized, monoclonal recycling antibody that targets the interleukin-6 receptor, reduced NMOSD relapse risk vs. placebo in two Phase 3 trials: SAkuraSky (satralizumab ± immunosuppressive therapy; NCT02028884) and SAkuraStar (satralizumab monotherapy; NCT02073279). Satralizumab is approved to treat aquaporin-4 IgG-seropositive (AQP4-IgG+) NMOSD. SAkuraBONSAI (NCT05269667) will explore fluid and imaging biomarkers to better understand the mechanism of action of satralizumab and the neuronal and immunological changes following treatment in AQP4-IgG+ NMOSD. Objectives SAkuraBONSAI will evaluate clinical disease activity measures, patient-reported outcomes (PROs), pharmacokinetics, and safety of satralizumab in AQP4-IgG+ NMOSD. Correlations between imaging markers (magnetic resonance imaging [MRI] and optical coherence tomography [OCT]) and blood and cerebrospinal fluid (CSF) biomarkers will be investigated. Study design SAkuraBONSAI is a prospective, open-label, multicenter, international, Phase 4 study that will enroll approximately 100 adults (18–74 years) with AQP4-IgG+ NMOSD. This study includes two patient cohorts: newly diagnosed, treatment-naïve patients (Cohort 1; n = 60); and inadequate responders to recent (<6 months) rituximab infusion (Cohort 2; n = 40). Satralizumab monotherapy (120 mg) will be administered subcutaneously at Weeks 0, 2, 4, and Q4W thereafter for a total of 92 weeks. Endpoints Disease activity related to relapses (proportion relapse-free, annualized relapse rate, time to relapse, and relapse severity), disability progression (Expanded Disability Status Scale), cognition (Symbol Digit Modalities Test), and ophthalmological changes (visual acuity; National Eye Institute Visual Function Questionnaire-25) will all be assessed. Peri-papillary retinal nerve fiber layer and ganglion cell complex thickness will be monitored using advanced OCT (retinal nerve fiber layer and ganglion cell plus inner plexiform layer thickness). Lesion activity and atrophy will be monitored by MRI. Pharmacokinetics, PROs, and blood and CSF mechanistic biomarkers will be assessed regularly. Safety outcomes include the incidence and severity of adverse events. Conclusions SAkuraBONSAI will incorporate comprehensive imaging, fluid biomarker, and clinical assessments in patients with AQP4-IgG+ NMOSD. SAkuraBONSAI will provide new insights into the mechanism of action of satralizumab in NMOSD, while offering the opportunity to identify clinically relevant neurological, immunological, and imaging markers.
TL;DR: In this paper , the authors evaluated the effect of corticotrophin injection (RCI) and intravenous methylprednisolone (IVMP) on the extent of visual recovery following acute optic neuritis.
Abstract: BACKGROUND
Repository corticotrophin injection (RCI, Acthar Gel) and intravenous methylprednisolone (IVMP) improve the rate but not the extent of visual recovery following acute optic neuritis. RCI has adrenal-stimulating and melanocortin receptor-stimulating properties that may endow it with unique anti-inflammatory properties relative to IVMP.
METHODS
Individuals with acute optic neuritis of less than 2 weeks duration were prospectively enrolled and randomized 1:1 to receive either RCI or IVMP. Peripapillary retinal nerve fiber layer (pRNFL) and ganglion cell plus inner plexiform layer thickness (GC + IPL) were serially evaluated by OCT. In addition, patient-reported outcomes (PROs) for changes in fatigue, mood, visual function, depression, and quality of life (QOL) were measured, and high and low contrast visual acuity were recorded.
RESULTS
Thirty-seven subjects were enrolled (19 RCI; 18 IVMP); the average time from symptom to treatment was 8.8 days. At 6 months, there was no difference in the primary outcome: loss of average pRNFL thickness in the affected eye (RCI vs IVMP: -13.1 vs -11.7 µm, P = 0.88) 6 months after randomization. Additional outcomes also showed no difference between treatment groups: 6-month attenuation of GC + IPL thickness (RCI vs IVMP: -13.8 vs -12.0 µm, P = 0.58) and frequency of pRNFL swelling at 1 month (RCI vs IVMP: 63% vs 72%, P = 0.73) and 3 months (RCI vs IVMP: 26% vs 31%, P = 0.99). Both treatments resulted in improvement in visual function and PROs.
CONCLUSION
Treatment of acute optic neuritis with RCI or IVMP produced no clinically meaningful differences in optic nerve structure or visual function.

TL;DR: In this article , the authors investigated the effect of retinal atrophy in AQP4-IgG-associated encephalomyelitis (EAE) and myelin oligodendrocyte glycoprotein antibody-associated disorder (MOGAD) in mice.
Abstract: BACKGROUND AND OBJECTIVES
Mechanisms of visual impairment in aquaporin 4 antibody (AQP4-IgG) seropositive neuromyelitis optica spectrum disorder (NMOSD) and myelin oligodendrocyte glycoprotein antibody (MOG-IgG)-associated disorder (MOGAD) are incompletely understood. The respective impact of optic nerve demyelination and primary and secondary retinal neurodegeneration are yet to be investigated in animal models.
METHODS
Active MOG35-55 experimental autoimmune encephalomyelitis (EAE) was induced in C57BL/6Jrj mice, and monoclonal MOG-IgG (8-18C5, murine), recombinant AQP4-IgG (rAb-53, human), or isotype-matched control IgG (Iso-IgG, human) was administered 10 days postimmunization. Mobility impairment was scored daily. Visual acuity by optomotor reflex and ganglion cell complex thickness (GCC, 3 innermost retinal layers) by optical coherence tomography (OCT) were longitudinally assessed. Histopathology of optic nerve and retina was investigated during presymptomatic, acute, and chronic disease phases for immune cells, demyelination, complement deposition, natural killer (NK) cell, AQP4, and astrocyte involvement, retinal ganglion cells (RGCs), and Müller cell activation. Groups were compared by nonparametric tests with a p value <0.05 indicating statistical significance.
RESULTS
Visual acuity decreased from baseline to chronic phase in MOG-IgG (mean ± standard error of the mean: 0.54 ± 0.01 to 0.46 ± 0.02 cycles/degree, p < 0.05) and AQP4-IgG EAE (0.54 ± 0.01 to 0.43 ± 0.02, cycles/degree, p < 0.05). Immune cell infiltration of optic nerves started in presymptomatic AQP4-IgG, but not in MOG-IgG EAE (5.85 ± 2.26 vs 0.13 ± 0.10 macrophages/region of interest [ROI] and 1.88 ± 0.63 vs 0.15 ± 0.06 T cells/ROI, both p < 0.05). Few NK cells, no complement deposition, and stable glial fibrillary acid protein and AQP4 fluorescence intensity characterized all EAE optic nerves. Lower GCC thickness (Spearman correlation coefficient r = -0.44, p < 0.05) and RGC counts (r = -0.47, p < 0.05) correlated with higher mobility impairment. RGCs decreased from presymptomatic to chronic disease phase in MOG-IgG (1,705 ± 51 vs 1,412 ± 45, p < 0.05) and AQP4-IgG EAE (1,758 ± 14 vs 1,526 ± 48, p < 0.01). Müller cell activation was not observed in either model.
DISCUSSION
In a multimodal longitudinal characterization of visual outcome in animal models of MOGAD and NMOSD, differential retinal injury and optic nerve involvement were not conclusively clarified. Yet optic nerve inflammation was earlier in AQP4-IgG-associated pathophysiology. Retinal atrophy determined by GCC thickness (OCT) and RGC counts correlating with mobility impairment in the chronic phase of MOG-IgG and AQP4-IgG EAE may serve as a generalizable marker of neurodegeneration.

TL;DR: In this article , the authors performed a prespecified analysis of the CHAMPION-NMOSD global, open-label, multicenter, phase 3, externally controlled study aimed to evaluate the efficacy of ravulizumab in clinically relevant patient subgroups.
Abstract:
Objective:
This prespecified analysis of the CHAMPION-NMOSD global, open-label, multicenter, phase 3, externally controlled study aimed to evaluate the efficacy of ravulizumab in clinically relevant patient subgroups.Background:
CHAMPION-NMOSD (NCT04201262) is a study of ravulizumab in adults with anti-aquaporin-4 antibody-positive neuromyelitis optica spectrum disorder. Ravulizumab binds to the same complement component 5 epitope as eculizumab; however, its longer elimination half-life extends the dosing interval (every 8 versus 2 weeks).Design/Methods:
Patients (≥18 years) received a weight-based intravenous loading dose of ravulizumab (2400–3000 mg) on day 1, followed by maintenance doses (3000–3600 mg) on day 15 and once every 8 weeks thereafter. Concurrent placebo treatment was precluded owing to the availability of eculizumab and other treatments; the placebo arm from PREVENT (NCT01892345) was the external comparator. Prespecified efficacy subgroup analyses of time to first adjudicated on-trial relapse (primary endpoint) were conducted and safety outcomes were analyzed across subgroups.Results:
At baseline, 30/58 ravulizumab-treated patients were receiving monotherapy and 28/58 concomitant immunosuppressive therapy (IST): steroids (n=12), azathioprine (n=7), mycophenolate mofetil (n=6) or other (n=3). No ravulizumab-treated patient experienced a positively adjudicated on-trial relapse. Based on time to first adjudicated on-trial relapse, ravulizumab was superior to placebo in preventing on-trial relapse in monotherapy (HR, 0.021; 95% CI: 0–0.176; relapse risk reduction [RRR], 97.9%; p<0.0001) and IST groups (HR, 0.031; 95% CI: 0–0.234; RRR, 96.9%; p<0.0001). Significant differences versus placebo were seen in patients who had previously received rituximab (n=20; RRR, 93.7%; p=0.0078) or not (n=38; RRR, 98.1%; p<0.0001). Ravulizumab was superior to placebo in prespecified subgroups by age, sex, race and geographic region. Overall safety profile was consistent with that of ravulizumab across other approved indications.Conclusions:
The robust effect of ravulizumab on RRR was observed across all prespecified subgroups, including ravulizumab monotherapy, concomitant IST use, age, sex, geographic region, and prior rituximab use.

TL;DR: In this article , the authors reported the efficacy and safety of ravulizumab in anti-aquaporin-4 antibody-positive neuromyelitis optica spectrum disorder AQP4+ NMOSD.
Abstract:
Objective:
To report efficacy and safety of ravulizumab in anti-aquaporin-4 antibody-positive neuromyelitis optica spectrum disorder AQP4+ NMOSD.Background:
Ravulizumab binds the same complement component 5 epitope as eculizumab; its longer half-life enables an extended dosing interval (8 versus 2 weeks). CHAMPION-NMOSD (NCT04201262) is a global, open-label, phase 3 study.Design/Methods:
Adult patients received a weight-based intravenous loading dose of ravulizumab, then a maintenance dose on day 15 and every 8 weeks thereafter. Eculizumab availability precluded concurrent placebo control; the PREVENT (NCT01892345) placebo arm was an external comparator. Propensity scores were used to account for potential differences in patient characteristics between arms. Primary endpoint: time to first adjudicated on-trial relapse and relapse risk reduction (RRR). Secondary efficacy endpoints: adjudicated on-trial annualized relapse rate (ARR); clinically important worsening from baseline in Hauser Ambulation Index (HAI) score.Results:
Median (range) follow-up: 73.5 (11.0, 117.7) weeks for ravulizumab (n=58); 36.0 (1.9, 117.7) weeks for placebo (n=47). The primary endpoint was met; no patients had adjudicated relapses with ravulizumab versus 20 with placebo (RRR, 98.6%; p<0.0001). The ARR (upper 95% CI) was 0.00 (0.04) with ravulizumab: superior to a predefined comparator ARR (0.25; p<0.0001). Fewer patients experienced clinically important HAI score worsening with ravulizumab (2/58; 3.4%) than placebo (11/47; 23.4%; p=0.023); OR, 0.16 (95% CI, 0.03–0.77). Treatment-emergent AEs were reported in 93.1% (ravulizumab) and serious AEs in 13.8%: two vaccinated patients experienced meningococcal infection (2.4/100 patient-years). Both recovered with no sequelae; one continued the trial. No deaths were reported. Despite a longer follow-up (median treatment duration: 90.9 weeks), efficacy and safety data remain consistent with the primary treatment period. No relapses were observed (RRR: 98.7%).Conclusions:
Ravulizumab significantly lowered risk of relapse and HAI score worsening versus placebo in AQP4+ NMOSD, an effect unaffected by baseline characteristics differences. No changes to the known ravulizumab safety profile were identified.

TL;DR: Weinshenker et al. as discussed by the authors found that the F allele of the F176V polymorphism is associated with decreased IgG binding affinity and reduced efficacy of rituximab in NMOSD.
Abstract:
Objective:
To characterize the relationship between the rs396991 polymorphism and the treatment response in N-MOmentum trial participants.Background:
Inebilizumab, a humanized, afucosylated IgG1 monoclonal antibody that targets CD19 for B-cell depletion, is approved to treat aquaporin 4 (AQP4) immunoglobulin G positive (IgG+) neuromyelitis optica spectrum disorder (NMOSD). Afucosylated antibodies are engineered to enhance affinity for Fc receptor III-A (FCGR3A) receptors and maximize antibody-dependent cellular cytotoxicity. The F allele of the F176V polymorphism (rs396991) is associated with decreased IgG binding affinity and reduced efficacy of rituximab in NMOSD. Data from participants with different FCGR3A genotypes were compared for disease severity and response to inebilizumab at timepoints up to ≥4 years.Design/Methods:
N-MOmentum (NCT02200770) was a double-blind, phase 2/3 trial of inebilizumab in adults with NMOSD, with a 28-week randomized controlled period (RCP); (inebilizumab 300 mg or placebo on days 1 and 15) and an optional open-label period (OLP) of ≥2 years. A total of 142 participants (inebilizumab, n=104; placebo, n=38) consented for genotyping via TaqMan qPCR assay.Results:
V-allele carriers (V-allele genotype [V/V or V/F], n=74) and F/F–allele homozygotes (n=68) did not demonstrate a significant difference in baseline demographics or disease duration. Depletion of CD20+ B-cells was similar in V allele vs F/F allele participants (0.6 (0.1–3.2) vs 1.3 (0.5–4.2) cells/μL at end of RCP) and was sustained in both groups throughout the duration of the study. We did not find any difference in risk of relapse (OR 0.94 (0.39, 2.24)) or Expanded Disability Status Scale worsening (OR: 1.55 (0.54, 4.70)) in V vs F/F allele participants. Annualized attack rates (Standard Error of the Mean [SEM]) for patients on inebilizumab treatment were V/V 0.00 (0.00), V/F 0.10 (0.04), and F/F 0.06 (0.03).Conclusions:
Inebilizumab treated participants in the N-MOmentum trial did not demonstrate differences in clinical outcomes between those with F and V allele genotypes.

Abstract: Objective To increase compliance with Abnormal Involuntary Movement Score (AIMS) documentation for patients taking antipsychotics to recognize and treat tardive dyskinesia in the psychiatry outpatient clinic. Methods The Lean Six Sigma quality improvement (QI) model, utilizing DMAIC steps of define, measure, analyze, improve, control, was followed. Psychiatry attendings and residents were surveyed to assess reasons for AIMS non-documentation, and they ranked their preferred solutions to increase compliance. A random sample of patient charts for individuals on antipsychotic medications was obtained to determine AIMS documentation compliance prior to and following the implementation of improvements. Results The most highly ranked solution was implementing a one-hour AIMS training session. Three months post-intervention, a random sample of 60 patient charts showed that 87% (52/60) of patients had AIMS documented which was a significant increase compared to 3% (1/30) pre-intervention (p<0.001). Conclusion An annual, one-hour AIMS training session for residents improved rates of AIMS documentation.
TL;DR: In this paper , the psilocybin extract was administered to 14 healthy individuals to assess the physiological effects of 25 mg of the drug on their daily life, including their blood pressure and heart rate.
Abstract: This Phase I trial aims to inform the development of safety protocols for psilocybin-assisted therapy. Psychedelics, including psilocybin, are increasingly being recognized as a successful treatment option for many mental health concerns. In order to decrease the risks associated with its clinical use, more data is required regarding its physiological effects in healthy individuals. Safety assessments (heart rate, blood pressure, temperature, and ECG data), as well as adverse event evaluations were the primary outcome measures used to assess the physiological effects of 25 mg of psilocybin extract administered to 14 healthy individuals. We hypothesized that there would be a transient, clinically insignificant rise in both blood pressure and heart rate that would not result in any long-term adverse effects. No unexpected effects were observed, blood pressure and heart rate returned to normal as drug effects waned, and all participants had normal two-month follow-ups. Mean peak systolic and diastolic blood pressures during the psilocybin session were 145.93 (SD = 19.01) and 93.93 (SD = 9.75), respectively. While this represents a significant increase from baseline (p < 0.0001), a healthy cardiovascular system is capable of tolerating such levels for a longer time period than the brief duration of drug effects. Therefore, we suggest implementing focused and limited screening protocols to balance patient safety and accessibility. Secondary outcomes of this trial centered on the subjective effects of psilocybin, assessed via the QIDS-SR16 and the MEQ-30. There was a statistically significant decrease in QIDS-SR16 scores from baseline scores (M = 3.50, SD = 2.35) to eight-week follow-up scores (M = 1.86, SD = 0.86), p = 0.018. Mean MEQ-30 scores, assessed on day two and seven after the psilocybin session, indicate participants had full mystical experiences.
TL;DR: The N-MOmentum trial as discussed by the authors evaluated the attack identification process and adjudication committee (AC) performance in NMOSD patients with inebilizumab 300 mg or placebo.
Abstract: Background: The N-MOmentum trial investigated safety and efficacy of inebilizumab in participants with neuromyelitis optica spectrum disorder (NMOSD). Objective: Evaluate the attack identification process and adjudication committee (AC) performance in N-MOmentum. Methods: Adults (n = 230) with NMOSD and Expanded Disability Status Scale score ⩽8 were randomized (3:1) to inebilizumab 300 mg or placebo. The randomized controlled period was 28 weeks or until adjudicated attack. Attacks were adjudicated according to 18 predefined criteria. Magnetic resonance imaging (MRI) and biomarker (serum glial fibrillary acidic protein [sGFAP]) analyses were performed. Results: A total of 64 participant-reported neurological events occurred; 51 (80%) were investigator-determined to be attacks. The AC confirmed 43 of the investigator-determined attacks (84%). There was high inter- and intra-AC-member agreement. In 25/64 events (39%) and 14/43 AC-adjudicated attacks (33%), MRI was reviewed during adjudication. Retrospective analysis revealed new domain-specific T1 and T2 MRI lesions in 90% of adjudicated attacks. Increased mean sGFAP concentrations (>2-fold change) from baseline were observed in 56% of adjudicated attacks versus 14% of investigator-determined attacks rejected by the AC and 31% of participant-reported events determined not to be attacks. Conclusion: AC adjudication of NMOSD attacks according to predefined criteria appears robust. MRI lesion correlates and sGFAP elevations were found in most adjudicated attacks.
